[Industrial applications]

 The present invention relates to an onion root cutting soil sieving device for cutting onions cultivated in a field and at the same time shaking off soil attached to the onions and returning them to the ground.

[0002]

[Prior art]

 The onions planted in a line along the ground of the field are root-cut and dug up on the ground, then the soil attached to the onions is scraped off and left on the ground, and the surface of the onion turns brown. Dry until complete. Conventionally, root cutting work has been performed for root cutting work of onions planted in fields. A conventional root-cutting device is configured by horizontally and vertically moving a root-cutting blade that is inserted into the ground on a tow truck that is pulled after an agricultural tow truck such as a tractor. The root cutting blade that moves inside cuts off the root of the onion in the ground while digging up the ground, and at the same time digs the cut onion on the ground.

[0003]

[Problems to be solved by the device]

 However, the above root cutting device only cuts the root of the onion planted in the ground with the root cutting blade and floats it on the ground, so the onion dug up on the ground had a lot of soil on the surface. It is as it is. Therefore, if the onions are left to dry on the ground as they are, the onions will not be sufficiently dried due to the soil that has adhered to them, and they will grow secondarily even after dug up, resulting in poor color luster. is there. Therefore, in the past, it was necessary to manually shake off the soil adhering to the surface of the onion that had been root-cut and dug up on the ground.

An object of the present invention is to provide the conventional root cutting device as described above with a function of removing soil adhering to the cut onion.

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, an onion root cutting soil sieving apparatus of the present invention comprises a bogie towed by an agricultural towing vehicle, a root cutting blade which is horizontally attached to the bogie and vertically supported. It is provided immediately after the root cutting blade, and is provided with a soil-raising conveyor that picks up the onion rooted by the root cutting blade from the ground, conveys it backward, and discharges it again on the ground. .

It is preferable that the soil-conveying conveyor of the above-mentioned apparatus is constituted by a belt conveyor, and a large number of rods are laid horizontally at intervals slightly smaller than the diameter of the onion to constitute the belt of the belt conveyor.

Further, in the above apparatus, on both sides of the rear portion of the soil sieving conveyor, standing plates extending rearward along the ground are erected, and the mounting angles of these standing plates in a plan view are adjusted by an angle adjusting mechanism. It may be adjustable by.

[0008]

[Action]

 According to the above means, the root cutting blade is attached horizontally to the trolley towed by the agricultural towing vehicle, is supported so as to be able to move up and down with respect to the ground, and dives into the ground in the lowered position to Aligned with the height of the onion roots planted in. Immediately after the root cutting blade, a soil sieving conveyor is provided. When the root cutting blade moves under the ground as the towing vehicle travels, the root of the onion is cut, and the cut onion is dug up on the ground and picked up by the front end of the soil sifting conveyor. The onions placed on the soil sieving conveyor are discharged onto the ground again after the soil adhering to the surface is shaken off when being transported on the conveyor.

In addition, in the case where the belt of the belt conveyor is constructed by horizontally laying a large number of rods, the rods constituting the conveying surface are swayed in small steps due to the vibration generated at the time of driving. On the uneven surface of the body, the rooted onion rolls with a small bounce, rolling and moving, and the soil adhering to the surface is removed. In addition, the soil removed from the onion falls from the gap between the rods and returns to the ground. In the case where standing plates are erected on both sides of the rear part of the soil sieving conveyor, when the sewage plates move along the ground and the onions transported on the soil sieving conveyor are discharged onto the ground, By pushing the onion back toward the center of the conveyor with the shifting plate, it is possible to prevent the onions from spilling outward from the width of the conveyor and to arrange the onions discharged on the ground in a line. Further, when the angle of attachment of the both moving plates is adjusted by the angle adjusting mechanism, the manner in which the onions are pushed back and the width of the rows of other onions placed on the ground are adjusted.

[0010]

[Effect of device]

 As described above, the present invention is provided with the soil sieving conveyer for picking up the rooted onion from the ground and discharging it again onto the ground after the root cutting blade. By simply pulling the device, the root cutting of the onion planted in the field and the soil removal can be finished at the same time, and the onion can be placed on the ground with well soiled soil. Therefore, it is not necessary to manually shave off the soil adhering to the onion that has been cut and excavated as in the conventional case, and it is possible to reduce the excavation work.

In the case where the soil sieving conveyer is constituted by a belt conveyer and the belt of the belt conveyer is constructed by horizontally arranging a large number of rods, in the case where the rooted onion is vibrated, Since it can be rolled so that it rolls on the uneven transport surface created by, the soil attached to the surface can be effectively shaken off.

Further, in the case where standing plates extending rearward along the ground are erected on both sides of the rear portion of the soil sieving conveyor, the onions discharged from the soil sieving conveyor are sewn on both sides by the gathering plates. Since the rows of onions pressed down from the ground and discharged onto the ground can be neatly arranged with a predetermined width, collection work after drying can be easily performed.

Embodiment An embodiment of the present invention will be described below with reference to the drawings. The root cutting soil sieving device shown in FIGS. 1 to 3 is a bogie 1 which is connected to a rear part of an agricultural towing vehicle such as a tractor and is towed, and a root cutting horizontally attached to and supported by the bogie 1. The blade 2 comprises a soil sieving conveyor 3 which is arranged immediately after the root cutting blade 2 and an offset plate 4 which is attached to both sides of the rear portion of the conveyor 3.

The trolley 1 is connected to the rear part of an agricultural towing vehicle such as a tractor and runs on the ground while being pulled by the tractor. It has two horizontal frames 11 and 17 assembled in parallel, Wheels 12 are attached to both left and right ends of the horizontal frame 11. Both ends of the horizontal frames 11 and 17 are connected by a support frame 15 bent in a substantially side view shape, and a root cutting blade 2 to be described later is horizontally attached and supported across the lower ends of these support frames 15. I am doing it. A connecting piece 13 is provided at two intermediate portions of the front side horizontal frame 11, and a link plate a1 extending from the rear portion of the tractor is bent up and down on the connecting piece 13 via a connecting pin 13a serving as a pivot. It is rotatably connected. In addition, three pillars 14 are erected at the center of the horizontal frames 11 and 17 so as to form a triangular pyramid, and a ring extending from the rear portion of the tractor is provided at a connecting portion 14a provided at the apex thereof. The tip of the rod a2 is connected via a connecting pin 14a serving as a pivot.

As shown in FIG. 6, the wheels 12 provided at both ends of the horizontal frame 11 are pivotally supported on the lower ends of the leg members 12 a. The leg members 12a are vertically fitted and supported by supporting members 12a fixed to both ends of the horizontal frame 11 so as to be vertically movable. An adjusting screw 12d is vertically slidably inserted into the upper end of the support member 12a, and the lower end of the adjusting screw 12d is screwed into a screw tube 12c vertically attached and fixed to the leg member 12a. I am doing it. The height between the wheel 12 and the horizontal frame 11 can be increased or decreased by adjusting the handle 12e at the upper end of the adjusting screw 12d. The trolley 1 configured as described above is pivotally supported by the connecting pin 13a located coaxially and the connecting pin 14a in the high position (FIG. 1), and the trolley 1a is rotated by rotating both link plates a1 up and down. 1 moves up and down while maintaining a substantially constant angle.

The root cutting blade 2 cuts the root of the onion that extends into the ground, and digs the root of the onion on the ground. The root cutting blade 2 is formed by sharply cutting the side edges of a horizontally long steel plate, and is horizontally installed between the lower ends of the support frames 15 on both sides of the bogie 1, and is extended in the traveling direction as shown in FIG. It is attached and supported by inclining it so that the edge of the blade is facing downward. Immediately after the root cutting blade 2, a conveyor 3 for soil sieving is provided. The soil sieving conveyor 3 picks up the onions dug up by the root cutting blade 2 and shakes off the soil adhering to the onions while transporting them on the transport path. It is installed between the side plates 16. A drive shaft 31 is installed between the rear portions of the both side plates 16 and rotatably supported by the both side plates 16.

As shown in FIGS. 4 and 5, a cruciform sprocket 32 for receiving one end of a belt body 35 described later is attached to a portion of the drive shaft 31 located inside the side plate 16, and the drive shaft 31 is driven by the sprocket 32. It rotates with the shaft 31. On the other hand, a roller 33 that receives the other end of the belt body 35 is pivotally supported in a cantilever state at the front end portions of the side plates 16. The belt body 35 that is stretched between the sprocket 32 and the roller 33 is a chain 36 that is attached along the left and right side edges of the belt, and a large number of rod bodies that are stretched between these two chains 36. 37. Two rods 37 are arranged in parallel at a predetermined interval, and two rods 37 are integrally connected to each other through a pair of rods 37 connecting rod 37a.

Both ends of the pair of rods 37 are fixed to the elements 36 a of the chain 36, and a large number of rods 37 are installed between the chains 36. As a result, the belt body 35 becomes an endless wide belt. The belt body 35 is mounted on the outer side of the drive shaft 31, and both side portions thereof are wound around the outer circumferences of the sprocket 32 and the roller 33. The teeth of the sprocket 32 mesh with a gap between a pair of rods 37, and the belt 35 rotates as the sprocket 32 is driven. Further, both ends of each rod 37 are bent in a crank shape as shown in FIG. 4, so that the movement difference in the upward and downward directions generated when the rod 37 rotates at the front end of the conveyor 3 is caused. It takes a large amount to improve the effect of removing the soil, and the dug onion can be quickly picked up on the conveyor 3.

Both rollers 33 are rotatably supported by a shaft support plate 41 slidably attached to the side surface of the side plate 16. By rotating the shaft support plate 41 by adjusting the rotation of an adjusting screw 42, the sprocket 32 and the rollers are rotated. It is configured so that the axial distance between the belt body 35 and 33 is adjusted and the tension of the belt body 35 is appropriately maintained.

A pulley 51 is attached to one end of the drive shaft 31, and an endless belt 52 is stretched between the pulley 51 and a pulley 53 provided in front of the carriage 1. The pulley 53 is pivotally supported at one end of a shaft 54 extending from a mission box 55 installed at the center of the horizontal frames 11 and 17. The mission box 55 has an input shaft 56 protruding forward, and a driving natural joint a3 extending from the rear part of the tractor is detachably connected to the input shaft 56. As a result, the drive force from the drive universal joint a3 is transmitted to the drive shaft 31 of the conveyor 3 via the gear box 55 and the pulleys 53 and 51.

The soil sieving conveyor 3 having the above-described structure constitutes a conveying surface 35a having a wide width and a relatively short overall length, and the conveying surface 35a is positioned on the extension of the inclination of the root cutting blade 2. (Fig. 5). The distance between the rods 37 is set to be slightly smaller than the diameter of the onion, and the onions are rolled and transported backward on the transport surface 35a as the belt 35 is driven and rotated. When the belt body 35 is rotationally driven, each rod body 37 vibrates appropriately due to its own elasticity. The vibration causes the onion to roll while bouncing on the belt body 35.

A shifting plate 4 is attached to both sides of the rear end of the soil sieving conveyor 3. The displacement plate 4 is for preventing the rooted onion from rolling out from the width range of the conveyor 3 when the onion conveyed by the soil sieving conveyor 3 is discharged from the end of the conveyor. is there. As shown in FIGS. 1 and 2, the both-side shifting plate 4 extends rearward from an intermediate portion on both sides of the conveyor 3, and a rear end portion thereof extends rearward from an end portion of the conveyor 3. The lower part of the shifting plate 4 is cut out according to the side shape of the conveyor 3 to prevent interference with the conveyor chain 36. Further, a rubber plate 4a is attached to the inner surface of the shifting plate 4 so as to partially project from the lower edge portion of the shifting plate 4 located behind the conveyor 3.

The pulling plate 4 fixes the bolts 43 penetrating the front end thereof to the side plate 16, and the angle adjusting plate 44 provided above the middle part is slid against the fixing plate 45 fixed to the side plate 16. Support by fixing the id adjustable. The angle adjusting plate 44 is provided with a long hole 44a extending in the width direction of the conveyor 3, and a bolt 46a protruding from the fixing plate 45 is inserted into the long hole 44a and is fixed by a nut 46b. The plate 4 itself is constructed so that the angle can be adjusted within the range of the elongated hole 44a.

Further, as shown in FIG. 3, the both-side shifting plate 4 is supported in a state in which the extended end is slightly inclined so that the extending end faces the center of the conveyor 3. This is because the onion discharged from the rear end of the conveyor 3 is positively moved toward the center of the conveyor 3 by the inclination of the moving plate 4, and the delicate angle adjustment is performed by the angle adjusting mechanism described above. By.

Next, a description will be given of the onion digging work performed using the soil sieving apparatus for an onion constructed as described above. The device of the present application is connected to an agricultural tow vehicle such as a tractor, and connects both link plates a1 and link rods a2 protruding from the rear part of the tow vehicle to the connection piece 13 and the connection part 14a, respectively, and further, The drive universal joint a3 is connected to the input shaft 56 of the mission box 55. In addition, it is preferable to install a conical onion leaf wiping device in front of the front wheels of the towing vehicle, so that the onion plant the leaves lying next to the ridge on which the towing vehicle is traveling. It can be avoided by spilling over the ridges that are torn, and the wheels of the towing vehicle can prevent trampling the onion leaves lying beside the ridges.

When the link plate a1 is driven to lower the device, both wheels 12 are installed, and at the same time, the root cutting blade 2 is inserted into the ground. The depth of insertion of the root cutting blade 2 is set by the positional relationship between the wheels 12 and the root cutting blade 2, but the root cutting blade 2 is adjusted by turning the adjusting screw 12d to adjust the height of the wheel 12. Adjust the edge of blade 2 so that it passes slightly below the onion planted in the field.

When the towing vehicle is run along the ridge on which the onion is planted while the device is lowered, the root cutting blade 2 inserted into the ground moves horizontally in the ground and is planted in a line. The roots of the onions are cut one after another, and the above onions are dug up on the ground as the root cutting blade 2 passes through the ground (Fig. 5). The onion dug up on the ground is scooped up by the belt body 35 that rotates from the bottom to the top at the front end of the soil sifting conveyor 3, and is transported while rolling on the transport surface 35a. The onion conveyed on the conveying surface 35a rolls while slightly bouncing on the unevenness of the rod body 37 which vibrates appropriately during driving, whereby the soil adhering to the surface is effectively shaken off. The soil dropped from the onion passes through the gap between the rods 37 and falls to the ground.

The onion conveyed to the rear end of the conveyor 3 is discharged to the ground. When the conveyed onion is discharged onto the ground, both shifting plates 4 push back the onions that are about to spill out to both sides and drop them on the ground. As a result, the onions discharged onto the ground are aligned in a line according to the width of the conveyor 3. The onions dug up as described above are collected after being dried for a predetermined number of days, but they are neatly arranged along the ridge of the field with a certain width, so that the collection device can smoothly collect them.

In the above embodiment, the conveyor 3 is a belt conveyor in which a large number of rods 37 are arranged in parallel to form the belt body 35 that serves as the transport surface 35 a. The present invention is not limited to the one in which the rod bodies 37 are arranged side by side to form the belt body 35, and any material that can shake off the soil adhering to the onion may be used. Further, in the above-described embodiment, the onion board discharged from the conveyor 3 is arranged with a constant width by providing the moving board 4 at the rear part of the conveyor 3, but the moving board 4 must be attached. It is not something that cannot be achieved.
