Abstract

[Problem] A dairy cow raised in a cowshed sits on a cowbed with manure falling on it, so that the breast is not hygienic and may cause mastitis. The dirt on the cow bed was cleaned by human hands, but the cleaning work was heavy labor, and both the dairy cow and the person felt great stress due to the bad smell caused by manure.
An excrement collection tool for receiving excrement is provided below the anus of a dairy cow, and the excrement is collected at the excrement collection point reliably and without odor spreading. This keeps the cow bed clean and the workers feel no stress.

Description

  The present invention relates to a livestock excrement collection tool, and in particular, to a cattle excrement collection tool that prevents the generation of malodor caused by excreta trapped in a barn when dairy cattle are raised in a tethered manner. Further, the present invention relates to an odorless barn that eliminates the generation of malodors.

  In recent years, in dairy farming, feeding and breeding methods for dairy cows have been studied in order to increase milking amount. In particular, it has been found that by managing dairy cows cleanly, it is possible to suppress the occurrence of epidemics such as mastitis and increase milk productivity.

  There are several ways of dairying. If the land is large, and there are a large number of animals, a free-burn system will be used. However, in the case of the freeburn method, cows excrete everywhere, and there is a problem that dairy cows lie on manure and cannot be kept clean. In order to solve this problem, a free stall type barn was introduced.

  In the free stall method, a passage for dairy cows to move between feeding areas, milking rooms, etc., and a cow bed (stall) that faces each of the dairy cows and can be individually dedicated to each cow are secured. That is, the cows that have entered the stall are controlled in position and posture, and manure is mainly discharged to the passage side. Thus, manure on the passage side only has to be processed, and there is a merit that the labor of cleaning can be greatly saved compared with the case of the free burn method. Further, if a so-called burn cleaner (for example, Patent Document 1) that collects and transports manure is disposed on the passage side, the operation becomes easier.

  However, even in the free stall system, there remains a problem that manure falls during the stall due to the size and movement of each cow and the cow becomes dirty with manure.

  In order to solve this problem, Patent Document 2 discloses an invention that aims to determine a place where a cow will excrete and excrete at that place, while a free-burn breeding method. Here, an excretion place (toilet-type device) that should be called a dairy cow's toilet is provided in a free-burn cowshed. In this toilet-type device, the direction of the dairy cow is controlled, and a feces and urine collection device using “snow” is provided in the vicinity where the manure falls. Further, a cleaning device for cleaning the vicinity of the dairy cow's breast is provided on the side surface of the toilet-type device.

  Then, when a detection device is placed on the tail of the cow and the cow tries to excrete in a place other than this toilet-type device, an unpleasant sound is heard from the speaker placed near the cow's ear and the cow is excreted. It is to learn the place.

  Further, Patent Document 3 discloses an excrement guidance device that is moored to a rear body of a dairy cow and transfers manure to a predetermined place. This is like dairy cow pants, and the dairy cow wearing this looks like a bag on the tail.

  The free burn method and free stall method are suitable for dairy farming in a relatively large area. However, when dairy farming is performed on a small area of land, a so-called tethering method is adopted in which the cows are bred and milked while being connected to the stall. In the case of such a tethered cowshed, it is not easy to determine an excretion place as in Patent Document 2. It is preferable to rear the facility by arranging a facility such as a burn cleaner on the side of the passage that is also outside the stall.

  It can be said that the excrement guide tool disclosed in Patent Document 3 is an excretion processing apparatus suitable for such a connection type cowshed. However, the excreta treatment leads not only to the problem of dairy cow health management but also to the problems of worker stress and the location of the barn. That is, malodorous components such as hydrogen sulfide and methyl mercaptan that are generated when manure from dairy cows is subjected to anaerobic fermentation cause stress to workers, and it is difficult to install a cowshed near the house.

  Conventionally, such malodorous components are naturally diffused in the atmosphere, and therefore a barn requires a large space. In other words, there was a problem that it was not easy to make a small barn. From this point of view, Patent Document 3 seems to avoid the situation where manure is sprayed around the cow, but there is no mention of malodor treatment.

  The present invention has been conceived in view of such problems, and cattle excrement collection tool and excrement collection device for rearing dairy cows cleanly and constructing an environment free of stress for workers and the like are disclosed. The odorless barn used is provided.

In order to solve the above problems, the present invention first provides a livestock excrement collection tool. More specifically, the livestock excrement recovery tool of the present invention is an excrement recovery tool for recovering excrement from livestock moored near the excrement recovery point and transferring it to the excrement recovery point,
Fixing means to be placed on the livestock body,
A body part to be placed below the anus of the livestock,
A cylindrical extension connected to the lower opening of the main body with a bending angle with the main body,
A connection band connecting the opening of the extension and the excretion collection point;
Covering the upper opening of the main body and having a tail hole for penetrating the tail of livestock,
A cover anchoring string connecting the upper end of the cover part and the fixing means;
An upper locking string for connecting the upper end of the main body to the fixing means;
A lower anchoring string for connecting a lower end of the main body to the fixing means is included.

  The excrement collection | recovery tool of this invention is a connection channel | path arrange | positioned under the anus of livestock (dairy cow) and connecting to an excretion collection point. In particular, pay attention to raising the tail when cows excrete, when the tail rises, the cover part is pulled up, and the upper opening of the main body part for collecting excrement is located just below the anus or vulva Thus, the excreta can be suitably collected.

In addition, the livestock excrement collection apparatus of the present invention,
The above excrement collection tool,
A waste collection point connected to the waste collection tool;
A collection path disposed below the excrement collection point, for collecting and transferring excreta sent from the excrement collection tool;
An excrement processing apparatus disposed at a transfer destination of the recovery path and processing the manure;
A suction means connected to the excrement collection tool and a sensor for detecting that excretion has been performed;
It includes a control device that operates the suction means in response to a signal from the sensor.

  If it is the excrement collection apparatus of this invention, since the excrement of livestock is transferred from an excrement collection point to an excrement disposal apparatus, a dairy cow will not be in a prone position with the stall covered with own excrement. Therefore, the breast is not contaminated with bacteria. Moreover, when excretion is performed, the excrement collection tool is cleaned while exhausting, so that it is possible to suppress the generation of malodor due to excretion of livestock.

The odorless barn of the present invention is
A semi-enclosed building provided with the waste collection device and the waste collection device;
An air conditioner for introducing outside air into the semi-sealed building through a filter;
It has a fan which exhausts the air of the semi-sealed building outside in the state where the inside of the semi-sealed building was made into a positive pressure.

  Since the odorless barn of the present invention has the excrement recovery apparatus of the present invention, malodor associated with urination is eliminated from the barn. Therefore, since the inside of the barn can be in a semi-sealed state with a positive pressure, it is possible to prevent the entry of pests and viruses from the outside.

  Since the excrement collection device of the present invention collects not only the excrement but also the odor related to the excrement at the same time, there is an effect that the malodor related to the excrement can be eliminated from the environment where the cow is raised. .

  In addition, the barn equipped with the excrement collection apparatus of the present invention can be managed in a semi-sealed state where no pests can enter from the outside, and even the entry and exit of humans can prevent the invasion of viruses. .

  Furthermore, in the open type barn, the odor of the excrement is released to the atmosphere, so the height of the building is increased, and thus the temperature control is difficult, but the barn equipped with the excrement recovery apparatus of the present invention has a bad odor. Because it does not come out, ventilation of the cow's body odor and air conditioning control of the barn are possible. In addition, since cooling is possible, the tendency of the milking amount of dairy cows to be reduced can be improved, particularly in summer.

  Although the excrement collection | recovery apparatus of this invention is demonstrated using figures, the following description shows an example of embodiment of this invention, and can be changed unless it deviates from the meaning of this invention.

(Embodiment 1)
FIG. 1 shows a schematic view of the excrement collection apparatus 10 of the present invention. The excrement collection apparatus 10 of the present invention is used as a follower for at least one stall 12 for connecting individual cows, a collection path 14 provided behind the stall 12, and a cow for cows connected to the stall 12. The excrement collection tool 16 attached and connected to the recovery path 14, the suction pipe 31 connected to the excretion recovery tool 16, the cleaning liquid pipe 32, the hot air pipe 34, the sensor 33, and one end of the recovery path 14. A waste disposal device 18.

  Further, a suction device that sucks the suction pipe 31 with a negative pressure, a cleaning liquid supply device that supplies the cleaning liquid to the cleaning liquid pipe 32, a hot air device that sends warm air to the hot air pipe 34, and a control device 19 that controls the whole are provided. Have. The suction device, the cleaning liquid supply device, and the hot air device are not shown. Further, the cleaning liquid cleans and cleans the excretion part (not shown) of the dairy cow, the excrement collection tool 16 and the recovery path 14, and in order to prevent the growth of microorganisms, for example, ethanol or ozone water. The temperature is preferably 30 ° C. to 40 ° C.

  The stall 12 is a space in which individual dairy cows provided in the barn are arranged. Usually, a space surrounded by a U-shaped fence is suitable, but it is not limited to this. In order to separate between adjacent cows, it is preferable that there is a fence between adjacent cows. Dairy cows are moored from their heads into a fence with their buttocks facing the aisle.

  When viewed from the excrement collection apparatus 10 of the present invention, the stall 12 can be said to be a means for mooring the excreted dairy cow in the vicinity of the collection path 14. Even if it is a connection method, if there is not a certain degree of freedom of action, dairy cows will be stressed and milking will be reduced. Therefore, here, the vicinity means the distance within which the excrement collection tool 16 is not detached from the cow or the collection path 14.

  In the free stall method, feces and urine may fall into the stall and contaminate the stall due to the positional relationship between the anal position in the standing position of each cow and the excrement collection groove provided on the passage side. However, in the excrement recovery apparatus 10 of the present invention, the excrement recovery tool 16 attached to the cow transfers the excrement to the recovery path 14, so that the excrement does not fall into the stall 12. Moreover, since the excrement collection | recovery tool 16 is made into a negative pressure (suction), the odor at the time of excretion does not leak outside. Therefore, the worker is not stressed with a bad smell.

  The collection path 14 is a excrement transfer path provided on the path side 9 of the stall 12. The recovery path 14 has a sealed structure except for the connecting portion with the excrement recovery tool 16. This is to prevent odors from leaking outside. Moreover, the conveyor 40 (it demonstrates in FIG. 6 mentioned later) which conveys the droppings in the collection path 14 is provided. That is, the manure that has entered the collection path 14 from the excrement collection tool 16 is transported on the conveyor 40.

  An excrement disposal apparatus 18 is disposed at the tip of the collection path 14. The excrement disposal apparatus 18 may be provided outside the barn. This is because it is not necessary to keep a large amount of manure in the barn. Feces are composted. Urine is also purified. In purification treatment, it is divided into disinfectant, deodorant and regenerated water, sludge and waste water. The waste water is a solution containing an irreproducible ammonia component, and may be discarded or regenerated as a chemical product. Sludge is a solid matter in urine and a small amount. This is combined during composting and becomes compost. Water is used again as a cleaning solution, and those that can also use bactericides and deodorants are used again.

  On the other hand, the odor collected by the excrement collecting tool 16 may be directly released outside the barn. The bad odor is caused by the fact that urea, which is the main component of urine, touches the air and changes to ammonia, or hydrogen sulfide produced by fermentation of feces, so the odor immediately after defecation is not so strong. Rather, the elimination of malodor must be focused on the disposal of excreted excreta. That is, it is important not to retain manure in the barn. The excrement recovery apparatus 10 of the present invention quickly transfers excreted excreta outside the barn without retaining it in the barn.

  As described above, the excrement collection apparatus 10 according to the present invention is configured to discharge the excrement and odor excreted freely by a cow raised in a space called a stall 12 to the outside of the barn in a sealed state. Has almost no odor. In addition, manure, which is the source of malodor, is collected in one place in a sealed state, and fertilized and purified. Therefore, the dairy cow's breast in the stall is not contaminated, and the worker is not subjected to stress due to odor.

  Next, each component will be described in more detail.

  The external appearance of the excrement collection | recovery tool 16 which concerns on FIG. 2 at this invention is shown. Referring to FIG. 2 (a), the excrement collection tool 16 of the present invention has a cylindrical main body 20 applied between the thighs of the cow, and the main body 20 and the bending angle at the lower opening of the main body 20. A cylindrical extension 21 that is connected, a cover 22 that covers the upper opening of the main body 20, locking strings 24, 25, 26 connected to the upper and lower ends of the main body 20, and locking It has a fixing wire 28 for fixing the strings 24, 25, 26 and a fixing tool 29 for fixing the fixing wire 28 to the neck of the cow.

  The main body 20 has a cylindrical shape with one surface having a vertical surface 20a that is substantially flat or has a slight curvature. The vertical surface 20a is a portion applied between the thighs of the cow, and is located just on the body side from the anus and the vulva. That is, manure falls inside the cylindrical main body 20. The extension part 21 is a cylindrical body connected to the main body part 20 with a bending angle. Although the shape of the connection part of the main-body part 20 and the extension part 21 is not specifically limited, It is necessary to connect without a gap. This is because manure flows here. Moreover, it is desirable that the inside of the joint between the main body 20 and the extension 21 is formed smoothly. This is because if there are irregularities on the inside of the seam, feces and urine will accumulate there, causing odors.

  The inner surfaces of the main body 20 and the extension 21 are preferably subjected to a treatment that makes it difficult for manure to adhere, such as a peeling treatment. The excrement collection tool 16 of the present invention is connected to the cleaning liquid pipe 32, and after excretion, the cleaning liquid can be flowed into the excrement collection tool 16. However, it is more preferable that the inner surface is very slippery and the urine falls in the excrement collecting tool without flowing the cleaning liquid.

  A connection band 27 that is connected to the excrement collection point 35 is disposed at the opening of the extension portion 21. Although the connecting band 27 is moored to the stall 12 and its movement is restricted, the cow 27 moving freely to some extent and the excrement collection point 35 provided at a predetermined position of the collection path 14 are hermetically connected. It is a telescopic cylinder. It is preferable that the rubber is stretched to some extent, such as rubber, and the inside is smoothly formed. This is because feces and urine pass inside, and they are caught and do not remain.

  The cover portion 22 covers the upper opening 20 b portion of the main body portion 20. Also, a tail hole 23 is formed for keeping the tail out. The cover portion 22 closes the upper opening 20b of the main body portion 20 so that the odor after excretion does not leak. Further, when the cow excretes, if the tail is passed through the tail hole 23 in order to raise the tail, the cover portion 22 is pulled up by the raised tail, and as a result, the upper opening 20b of the main body portion 20 is opened to the anus. It becomes easy to be located just below. Therefore, the cover part 22 does not need to have so much elasticity.

  The locking string includes an upper locking string 25 that connects both ends of the upper end of the vertical surface 20 a of the main body 20, a lower locking string 26 that connects both ends of the lower end of the vertical surface 20 a of the main body 20, and the cover unit 22. It consists of the cover securing string 24 which connects two places of the upper part of. These are used when the excrement collection tool 16 is attached to the cow drive. In particular, the lower strap 26 greatly stretches when the cow collects the excrement collection tool 16 backward when the cow takes a posture such as lying down, so that at least the portions 26a and 26b close to the main body 20 are stretchable. A high one is desirable.

  Moreover, it has the fixing wire 28 which fixes these fixing straps to the cow, and the fixing tool 29 which fixes the fixing wire 28 to the neck of a cow. The fixing tool 29 is fixed to the neck of the cow by turning, and may have a collar shape. The fixed wire 28 is, for example, a wire that extends from the upper end of the neck portion through the shoulder to the back and back. The fixing wire 28 may be made of a resin having elasticity, and is not necessarily made of metal. Note that the fixing means 30 is constituted by the fixing tool 29 and the fixing wire 28.

  The lower locking string 26, the upper locking string 25, and the cover locking string 24 are fixed in this order at the position of the fixing wire 28 close to the fixing tool 29.

  Referring also to FIG. 2 (b), a suction pipe attachment port 31 i is formed on the upper surface of the extension portion 21. A suction pipe 31 for sucking the odor of manure is attached here. Further, a cleaning liquid injection port is provided inside the boundary between the upper end of the main body portion 20 and the cover portion 22, and a cleaning liquid pipe mounting port 32i is formed outside. A cleaning liquid pipe 32 is attached here.

  Further, a hot air outlet may be formed adjacent to the cleaning liquid outlet. Accordingly, the hot air pipe attachment port 34i is also provided on the outside of the main body 20 adjacent to the cleaning liquid pipe attachment port 32i. The hot air pipe 34 is attached to the hot air pipe attachment port 34i. A suction device (not shown) and a suction pipe 31 constitute suction means, a cleaning liquid supply device (not shown) and a cleaning liquid pipe 32 constitute cleaning means, and a hot air device (not shown) and the hot air pipe 34 show hot air drying means (for example, , Electric heater warm air, boiler warm air, etc.).

  A sensor 33 is disposed on the upper side surface of the main body 20. This is a detector that detects that the cow has excreted and notifies the control device 19 of it. What is detected may be an action taken when the cow excretes, such as infrared rays, odor, and tail movement, or may detect the excrement directly. Wireless communication is preferable with the control device 19. This is because the cow moves to some extent, so there is a risk that the wire will get tangled.

  FIG. 3 shows a state in which the excrement collection tool 16 of the present invention is attached to the rearing cow in the standing posture. First, the fixing tool 29 is fitted to the neck of the cow. At this time, the fixing wire 28 is fixed so as to turn to the back side. The fixing wire 28 is arranged along the back and waist from the shoulder. Next, the vertical surface 20a of the main body 20 is placed between the thighs of the cow, and the upper locking string 25 is turned from both sides of the tail and locked at a predetermined position 28b of the fixing wire 28. It is more preferable that locking wires 28a to 28c and the like are formed on the fixing wire 28 in advance.

  Then, the lower strap 26 is passed from between the thighs to the hind limbs and the breasts, is extended from the front of the thighs to the back and waist, and is locked at a predetermined position 28 a of the fixing wire 28. The main body 20 is fixed to the lower part of the anus of the cow by the lower locking string 26. Finally, the tail is passed through the tail hole 23, the tip of the cover portion 22 is applied to the anus and the base of the tail, and the cover fastening straps 24 at both ends are turned from both sides of the tail to engage the fixing wire 28 at a predetermined position 28c. Stop.

  Next, the suction pipe 31 is connected to the suction pipe attachment port 31i, and the cleaning liquid pipe 32 is further connected to the cleaning liquid pipe attachment port 32i. Further, the hot air pipe 34 is connected to the hot air pipe attachment port 34i.

  When the cow excretes in the state as described above, excretion is detected by the sensor 33 disposed at the upper end of the main body 20, and air is sucked by the suction pipe 31. The suction does not need to be performed with such a strong negative pressure, and may be such that air flows from the periphery to the gap of the cover portion. This is because if the odor does not leak outside, it will not smell. Note that suction may be performed not only during excretion but also throughout.

  Then, the cleaning liquid may be ejected from the cleaning liquid ejection port formed on the inner surface of the main body 20 through the cleaning liquid pipe. The cleaning liquid may be water, but is preferably water mixed with a deodorizing liquid.

  Furthermore, in order to clean or disinfect the cow's anus and vulva, ozone water or ethanol-containing water at a temperature about 5 ° C. higher than the body temperature of the cow is good, and the cleaning liquid may be finely sprayed from the cleaning liquid spout. The best. This is because, by spraying the cleaning liquid finely in a mist, it is possible to wrap and remove the dirt, and to prevent stress from being applied to the cow as much as possible. In addition, the amount of wastewater treatment can be reduced, and a large wastewater treatment facility is not required.

  Further, after washing the cow's anus and vulva for a predetermined time, the local part may be dried by applying warm air. By cleaning and cleaning the local area, the generation of bad odor is further suppressed. Note that the inside of the main body 20 may be sucked by the suction means while the hot air is being applied.

  The excreted excreta flows along the extension 21 bent from the bottom of the main body 20 together with the cleaning liquid, passes through the connection band 27 from the end of the extension 21, and is discharged from the excrement collection point 35 to the collection path 14. These operations are performed by the control device 19 receiving a signal from the sensor 33 instructing the suction device, the cleaning liquid supply device, and the hot air device. In addition, in FIG. 1, although the control apparatus 19 was arrange | positioned on the side surface of the excrement disposal apparatus 18, the arrangement | positioning location of the control apparatus 19 is not limited here.

  FIG. 4 shows the movement of the tail when the cow excretes and the movement of the excrement collection tool 16 of the present invention. Note that the suction pipe 31, the cleaning liquid pipe 32, and the hot air pipe 34 are not shown. With reference to Fig.4 (a), a normal cow rocks a tail to the right or left in a standing posture, or shakes it up. At this time, the main body 20 is brought into close contact with the body part of the cow, just behind the breast, by the highly elastic parts 26a and 26b (not visible behind the cow in this figure) of the lower strap 26. It has been.

  When a cow excretes, be sure to raise the tail until it is almost horizontal (see FIG. 4B). At this time, in the excrement collecting tool 16, the tail hole 23 of the cover part 22 is pulled up together with the tail. And the upper opening 20b of the main-body part 20 just shifts under the anus and the vulva part. Due to this movement, the upper opening 20b of the main body 20 does not fail to collect feces and urine.

  FIG. 5 shows a state of the excrement collection tool 16 in a prone position where the limbs are folded and a so-called sitting posture is obtained. Cows sit with their hind limbs folded and lie down when sleeping. When the cow sits, lower his buttocks while folding his hind legs. At this time, the excrement collection tool 16 is connected to the main body portion 20 at an angle at which the extension portion 21 is bent. Therefore, the excrement collection tool 16 touches the ground from the tip of the extension portion 21 along the bent angle. The lower part leaves the cow's body. The upper end of the vertical surface 20a is fixed below the anus. And when the cow sat down completely, as shown in FIG. 5, it is in the state which escaped to the back of the cow.

  When the cow stands up again, the highly stretchable portions 26a and 26b of the lower locking portion 26 contract, and the excrement collection tool 16 returns to its original position. As described above, the excrement collection tool 16 according to the present invention can collect the excrement of a standing cow, and even when the cow is in a sitting position or lying down, it does not disturb the behavior of the cow and is crushed by the cow. There is nothing. Further, although it is normally in close contact with the cow's body, when the tail is raised, the position of the upper opening 20b of the main body 20 is raised and located just below the anus, so that the excretion cannot be recovered.

  Next, the collection path 14 will be described.

  FIG. 6 shows a perspective view of the recovery path 14. The collection path 14 is installed in a groove excavated in the ground of the barn. At this time, the excrement disposal apparatus 18 is installed at one end of the collection path 14. The collection path 14 is preferably formed of a lightweight material such as plastic and excellent in airtightness.

  The shape of the cross section of the recovery path 14 is not particularly limited, but is preferably U-shaped. This is because the conveyor 40 is disposed in the collection path 14 as will be described later. The upper end of the U-shaped collection path 14 is open. A collection road cover 41 with high airtightness is fitted into the opening. This is because the recovery path 14 is a transfer path for transferring excrement, so that the odor of excrement is filled. Moreover, in order to clean the inside of the collection path 14, it is because cleaning cannot be performed unless the upper part is opened.

  An excrement collection point 35 for dropping manure from the connection band 27 of the excrement collection tool 16 into the collection path 14 is formed at a predetermined location of the collection path lid 41.

  A conveyor 40 is disposed in the collection path 14. This is because the urine dropped in the collection path 14 is transferred to the excrement disposal apparatus 18. The conveyor 40 is arranged at one end of a frame (not shown), an annular carrier belt 42 arranged between the frames, a head pulley 43 that drives the carrier belt 42, and at the other end. A tail pulley 44 is included. Carrier rolls 45 that support the carrier belt 42 are disposed at a plurality of locations on the frame.

  In addition, a V-shaped roll 46 is disposed below the carrier belt 42 in the transport direction so that the center of the carrier belt 42 is recessed while the carrier belt 42 is running. The carrier belt 42 may be any flexible material such as rubber. Feces and urine are held in the concave shape of the carrier belt 42 and transferred to the excrement disposal apparatus 18.

  The carrier belt 42 is hung on the head pulley 43, arranged in the shape of a carrier roll 45 and a V-shaped roll 46 arranged above and below the frame, and is also hung on the other tail pulley 44. The head pulley 43 that drives the carrier belt 42 is installed on the opposite side of the excrement disposal device 18 and is driven by a signal from the control device 19. When the head pulley 43 is rotated by a motor (not shown) connected to the drive shaft, the carrier belt 42 moves from the head pulley 43 side to the tail pulley 44 side.

  The head pulley 43 has a large outer diameter at both ends and a thin central portion. This is because the middle of the traveling carrier belt 42 is recessed. Since the V-shaped roll 46 is provided in the transfer direction of the carrier belt 42, the carrier belt 42 travels in a state where the middle is recessed during traveling.

  On the other hand, the tail pulley 44 is a pulley whose both ends and the middle are substantially flat. The center of the carrier belt 42 has a recessed shape up to the holding pulley 47 just before the tail pulley 44. However, after passing through the holding pulley 47, both ends of the carrier belt 42 are gradually flattened so that the transported manure is easily dropped into the collection tank.

  The excrement dropped from the excrement collection tool 16 into the collection path 14 moves on the carrier belt 42. At this time, the carrier belt 42 is transferred without spilling sideways because the center is recessed as described above. The feces transferred to the excrement disposal apparatus 18 is dropped from the carrier belt 42 into the treatment tank. The carrier belt 42 is cleaned with the cleaning liquid when the surface on which the manure is placed is turned down around the tail pulley 44. After that, it moves on the lower carrier roll 45 and moves to the tail pulley 44.

  FIG. 6B shows a cross-sectional view of the entrance portion of the excrement disposal apparatus 18. A cleaning nozzle 48 is provided at the lower end 49 of the entrance for receiving the conveyor 40 of the excrement disposal apparatus 18. Then, after the conveyor 40 transports the manure and drops it into the processing tank, the surface of the carrier belt 42 is cleaned with the cleaning liquid from the cleaning nozzle 48.

  Further, a deodorant injection port may be provided in the recovery path 14. When manure falls from the respective excrement collection tools 16 onto the carrier belt 42, the splashes fly to the inner wall surface of the collection path 14 and cause bad odors.

  Next, the excrement disposal apparatus 18 will be described. In FIG. 7, the structure of the excrement disposal apparatus 18 is shown. The excrement disposal apparatus 18 may be disposed outside the barn. This is because a large amount of manure is excreted from the barn every day, and a certain processing area is required. The excrement disposal apparatus 18 must collect manure from the conveyor 40 in the collection path 14 excreted into the ground. Therefore, a space is required below the conveyor 40. Therefore, the excrement disposal apparatus 18 is buried in the ground.

  Moreover, since manure is collected here, it becomes a part with the most bad smell. Therefore, sealing is necessary. A receiving port 54 for the conveyor 40 is also provided. As described above, the cleaning nozzle 48 is disposed at the lower end 49 of the receiving port 54. The upper end 55 of the receiving port 54 may be above or below the ground. However, it is not easy to make the space between the recovery path 14 airtight. Therefore, it is preferable to keep the inside of the excrement processing apparatus 18 at a negative pressure so that a bad odor does not leak from the inside of the excrement processing apparatus 18.

  Therefore, an exhaust device 56 is installed in the excrement disposal device 18. A filter 57 is provided at the exhaust port of the exhaust device 56, and adsorbs malodor in the excrement disposal device 18 before releasing air into the atmosphere.

  The manure carried by the conveyor 40 in the collection path 14 is first separated into feces and urine by “Sunoko” 50. “Sunoko” 50 may be a roller moving path in which rollers are arranged at narrow intervals. This is because feces with moisture can be reliably transferred. Urine falls into the urine storage tank 51, and feces fall into the fecal storage tank 52.

  The feces and urine stored in each storage tank are subjected to a decomposition process. Feces are composted along with dehydrated and aerobic bacteria. Urine is separated into wastewater such as moisture and ammonia and some solids by purification treatment. The solid content is composted together with feces as surplus sludge.

  As described above, the excrement collecting apparatus 10 of the present invention collects manure in the excrement processing apparatus 18 without diffusing malodor through the excrement collecting tool 16, and then performs a decomposition process. Can be reared. Moreover, it replaces with the conveyor 40 in the collection path 14, and you may use the commercially available burn cleaner.

(Embodiment 2)
The excrement collection apparatus 10 disclosed in the first embodiment is a relatively large scale as an excrement collection apparatus. However, the excrement collecting apparatus 10 has an effect of not causing malodor due to cattle manure to the barn. This effect has the effect that it is possible to seal a barn that has been mainly used to replace air in order to avoid bad odors.

  Sealing the barn is very desirable from the standpoint of protecting dairy cows from pests and viruses. For example, it is said that there is only a method of identifying a source and removing or spraying an insecticide as a countermeasure against a fly that is said to have a great influence on dairy cattle. Although measures to prevent the fly from entering the barn with a windbreak net with small eyes are also effective, the obstruction of air permeability immediately leads to the filling of bad odors. In addition, foot-and-mouth disease virus that causes livestock to be devastated cannot be prevented by conventional barns.

  On the other hand, if there is the excrement collection apparatus 10 of the present invention that does not emit bad odor, an odorless and sealed cowshed becomes possible. Therefore, the degree of sealing inside the barn can be made very high, and dairy cows can also be raised in a clean room by way of an air shower room that sterilizes the people who enter.

  FIG. 8 shows the configuration of the odorless barn 60 of the present invention. Since it is not necessary to worry about bad odor in the odorless barn 60 of the present invention, the building can be made smaller as long as there is no stress on the dairy cow. Also, the seam of the building is sealed. This is to prevent the entry of pests. On the other hand, since oxygen necessary for the cows in the barn 60 must be supplied, air from outside is introduced into the barn 60 through the air conditioner 61.

  Therefore, a fan 62 may be provided on a part of the wall of the barn, and the air in the barn 60 may be discharged to the outside while keeping the inside of the barn 60 at a positive pressure with respect to the outside. This is because the inside is a positive pressure, so there is no risk of pests and viruses entering the inside. Although not completely sealed as described above, a state in which the inside of the interior is kept at a positive pressure to substantially prevent pests from entering is called a “quasi-sealed state”. In addition, an air shower room may be provided in order to clean a normal barn. In the barn 60, the stall shown in the first embodiment and the collection path are provided, and each cow is attached to the excrement collection tool 16 described in the first embodiment and tied to each stall.

  Outside the barn 60, an air conditioner 61, a milking device 63, a waste processing device 18 of the waste collection device 10, and an overall control room 65 are arranged. In the odorless barn 60 of the present invention, the air conditioner 61 is an important element together with the excrement collecting apparatus 10. This is because it is necessary to maintain the air necessary for the sealed space and the interior of the barn 60 at an appropriate temperature. Adult dairy cows have fever and are relatively resistant to cold because food is processed by microorganisms in the body. However, it is vulnerable to heat and milking decreases during the hot summer months. Since the odorless barn of the present invention is a sealed space, dairy cows get tired unless the inside of the barn is kept at an appropriate temperature by air conditioning especially in summer. Conversely, milking does not decrease by temperature control even in summer.

  The air conditioner 61 uses a type that not only circulates internal air and controls temperature and humidity, but also introduces outside air into the barn. This is because the odor of manure does not occur, but the supply of oxygen is necessary. In this way, it is preferable to make a semi-sealed state especially in summer.

  Moreover, since the odorless barn of the present invention is a tethered type of barn, it is easy to manage individual dairy cows electronically. More specifically, the amount of work is further reduced in conjunction with the health management of each dairy cow and the automatic feeding device that supplies food and water according to the milking amount of each dairy cow.

  The present invention can be suitably used for a barn where dairy cows are raised.
