Since the vertical position on the conveyance end side hardly changes, the left and right first alignment conveyance conveyors 48, 48 to the left and right second alignment conveyance conveyors 56, 56 regardless of the vertical position on the conveyance start end side of the left and right first alignment conveyance conveyors 48, 48. Since the carrot can be taken over smoothly, the work efficiency is improved.

  Then, the width of the left and right second alignment transport belts 55, 55 is made narrower than the width of the left and right first alignment transport belts 47, 47, so that a plurality of carrots on the left and right first alignment transport belts 47, 47 are taken over. In this case, the carrots can be transported while being surely aligned one by one because they can be dropped into the left and right inner openings 33a and 33a or the left and right outer openings 33b and 33b.

  Furthermore, by providing left and right front correction guides 59 and 59 at the front end portions of the left and right inner openings 33a and 33a and the left and right outer openings 33b and 33b, the left and right first alignment and conveyance conveyors 48 and 48 are changed to the right and left second alignment and conveyance conveyors. Even if the transport posture of the carrots taken over by 56, 56 is disturbed, the left and right front correction guides 59, 59 adjust the transport posture. Since it is prevented that the space | interval with the inside carrot opens too much, work efficiency improves. Further, by providing left and right rear correction guides 60 and 60 at the rear end portions of the left and right inner openings 33a and 33a and the left and right outer openings 33b and 33b, the right and left second aligned transfer conveyors 56 and 56 convey the carrot. Even if it is disturbed, the transport posture is corrected and discharged, so all the carrots fall before the discharge and the distance between the carrots that have been aligned and transported and the carrots that are being aligned and transported may be too wide. As a result, work efficiency is improved.

  Further, by attaching left and right projecting members 61 and 61 projecting on the left and right inner openings 33 a and 33 a between the left and right ends of the rear portion of the first left and right first distribution plate 30 and the left and right front side correction guides 59 and 59, Carrots moving from the vicinity of the terminal end of the first distribution plate 30 to the left and right second aligned transport conveyors 56 and 56 enter the space between the terminal end of the first distribution plate 30 and the left and right front correction guides 59 and 59. Therefore, the work efficiency is improved without being interrupted, and the carrot is prevented from being damaged when it enters the space, thereby improving the commercial value of the carrot.

  Then, the left and right side walls 75, 75 are bent in the direction from the rear end of the left and right inner openings 33a, 33a to the end of the second sorting member 31 in the direction toward the inner end of the left and right second aligned transport conveyors 56, 56. By doing so, the end of the left and right side walls 75, 75 stabilizes the posture of the carrot that is transported through the transport end portions of the left and right second aligned transport conveyors 56, 56, thereby preventing disturbance of the posture of the carrot during discharge. .

  Although not shown, the alignment conveyance unit C can be arranged not only in the same conveyance direction with respect to the pumping conveyance unit B but also in a posture perpendicular to the conveyance direction of the pumping conveyance unit B. At that time, a takeover shooter is attached between the scooping conveyer 17 and the aligning and conveying unit 58 on the side separated from the scooping conveyer 17, and the carrots are put into both the left and right aligning and conveying devices 58 and 58. If it does in this way, the layout of the uplift conveyance part B and the alignment conveyance part C of a crop aligning apparatus can be changed freely, without reducing work efficiency, and arrangement | positioning according to the space of a work place is attained.

In addition, when the inclination angle of the takeover shooter is slow and the carrot movement is delayed, the hydraulic jack 2 of the storage section A is raised to change the vertical height of the pumping conveyance section B so that the inclination angle becomes steep. .
Further, depending on the work conditions such as a small number of carrots, the alignment conveyance may be performed only by the alignment conveyance device 58 in the vicinity of the scooping conveyance conveyor 17.

FIG. 7 shows a perspective view from the upper right of the aligning and conveying apparatus, FIG. 8 shows a perspective view from the upper left of the aligning and conveying apparatus, and FIG. 9 shows an enlarged partial left side view of the pumping and conveying apparatus B.
A pressing member 71 that presses the carrot N from above is disposed on the conveyance end side (upper side) of the pumping conveyance device B.
The conveyance end portion of the uplift conveyance device B is a portion where the carrot N is changed in the conveyance direction toward the pair of alignment conveyance conveyors 48 of the next left and right alignment conveyance device C, and the carrot N is changed in the conveyance direction. Sometimes it falls easily. Therefore, a pressing member 71 is disposed between the left and right pumping frames 7 and 7 at the transport terminal end of the pumping and transporting apparatus B from above the carrot N with a pressing force that does not interfere with the transport. A torque spring (not shown) is attached to the upper end side of the pressing member 71 so that the lower part can be freely opened and closed.

  The pressing member 71 is made of a thin plastic plate (for example, a PET plate having a thickness of 0.5 mm) to prevent the carrot N from falling, and at the same time, even if pressed by the carrot N, it will bend and will not damage the carrot N. . Moreover, the carrot N can be stably pressed by attaching the pressing member 71 so that the carrot N sequentially pumped up to the conveyance end portion of the pumping conveyance device B can be lightly pressed from the upstream side in the conveyance direction. Further, the pressing member 71 is in a forwardly raised position (an attitude in which the conveyance upstream side is floating) in order to prevent the carrot N from being clogged or caught.

  By providing a pressing member 71 that presses the carrot N from above on the conveyance end side of the pumping conveyance device B, it is possible to prevent the carrot N pumped and conveyed to the vicinity of the conveyance termination of the pumping conveyance device B from falling. The carrot N is not damaged by the impact, the commercial value of the carrot N is not impaired, the carrot N is not pumped up again from the storage hopper 4 or the receiving portion 74, and the work efficiency is improved as compared with the conventional case. .

  Further, drop-preventing string bodies 72 and 73 for preventing the carrot N from dropping from the pumping and conveying apparatus B are provided above the pumping and conveying apparatus B below the pressing member 71. The string bodies 72 and 73 are preferably made of a stretchable material such as rubber, and the carrot N fall prevention function is further enhanced by arranging the string bodies in two upper and lower stages.

  Further, by providing two fall prevention string bodies 72 and 73, it is possible to prevent the carrot N being pumped and conveyed from being lifted from the pumping and conveying apparatus B and to prevent the carrot N from being damaged by the impact of the drop. The product distance of the carrot N can be shortened without impairing the commercial value of the product, and the transport work efficiency can be improved as compared with the conventional one.

  Of the two string bodies 72, 73 for fall prevention, the lower second string body 73 is at a position where the height in the direction perpendicular to the conveyance plane is higher than the upper first string body 72 (for example, a position 20 mm higher). By arranging it, the carrot N falling over the first string body 72 and falling can be received by the second string body 73 and returned to the pumping conveyance device B. The distance between the first string body 72 and the second string body 73 is about 100 to 200 mm corresponding to the length of one carrot N, and the carrot N can pass between the two string bodies 72 and 73. The intervals are as follows.

  A receiving portion 74 is disposed below the second string body 73 so that the receiving portion 74 can receive the carrot N falling over the second string body 73. A buffer member 76 made of a soft plate material such as vinyl chloride resin or rubber is provided on the upper surface of the receiving portion 74. When the carrot N falling on the buffer member 76 is received, the buffer member 76 is folded, so that the impact of the drop is relieved and the carrot N can be prevented from being damaged. In addition, if a plurality of cuts are made in the buffer member 76, the carrot N is easily bent and the dropped carrot N does not remain on the buffer member 76.

  Further, the height of the buffer member 76 in the vertical direction with respect to the conveyance plane of the pumping conveyance device B is higher than the height of the second string body 73, so that the falling carrot N can be reliably received. N has the effect of preventing damage and reducing the distance of falling movement.

  A buffer plate 77 made of a soft plate material such as vinyl chloride resin or rubber that can open and close the internal space of the receiving portion 74 is desirably attached to the lower side of the receiving portion 74. The buffer plate 77 makes it easier for the carrot N that has fallen between the receiving portion 74 and the conveying roller 15 to move, and the work efficiency is further improved.

  The buffer plate 77 is configured to swing in conjunction with the transport speed of the transport roller 15 of the draw-up transport device B. An oscillating device Y that oscillates the buffer plate 77 of the receiving portion 74 is provided in conjunction with the driving of the lifting and conveying device B. Thereby, the buffer plate 77 of the receiving portion 74 can be swung in conjunction with the driving of the draw-up conveyance device B.

  As shown in FIG. 9, the swing device Y is provided with a cam roller 81 on a drive shaft 79 a of a drive device (motor) 79, a base portion of a crank rod 82 is provided on the cam roller 81, and a tip roller 84 is provided at an end portion of the crank rod 82. Is provided and configured. Further, the base portion of the link cam 85 is attached to either the left or right pumping frame 7, and the end portion thereof is attached to the crank rod 82, and the end portion side of the link cam 85 rotates as the crank rod 82 rotates. That is, the crank rod 82 has a cam roller 81 attached to the base side, a tip roller 84 attached to the tip side, and the end side of the link cam 85 attached between the cam roller 81 and the tip roller 84. The crank rod 82 is rotated by a motor 79. The tip roller 84 is configured to periodically contact the inner surface of the receiving portion 74 with a buffer plate 77 biased by a spring 86.

By providing the oscillating device Y, when the carrot N falling vertically is received by the buffer plate 77, the posture can be changed by tilting it horizontally, making it difficult for the carrot N to fall from the pumping conveyance device B. Efficiency is improved than before.
When the carrot N is conveyed sideways, the carrot N is positioned between the front and rear of the conveyance roller 15 of the pumping conveyance device B. Therefore, even if the carrot N is dropped, the conveyance roller 15 is received, so that it is difficult to fall.

  Thus, by providing the receiving portion 74 for receiving the carrot N that has fallen on the conveyance start end side of the pumping conveyance device B, the carrot N can be received before dropping to the hopper 4, and the carrot N is It can be prevented from being damaged, the commercial value of the carrot N is not impaired, the distance that the carrot N is transported can be shortened, and the transport work efficiency is improved as compared with the prior art.

  A detection member (photoelectric sensor) 90 for detecting the retention of the carrot N at the conveyance start end of the pumping conveyance device B is provided on the inner surface of the plate member 90 a provided on one side wall of the conveyance start end side end of the receiving portion 74. A light receiving plate 90b provided on the other side wall of the conveying start end of the pumping conveying device B receives a signal from the detecting member 90 and moves the carrot N into the conveyor S for a predetermined time (basic 1 second, 0 to 7 seconds). A control device (not shown) for stopping is provided.

A protective member 91 is disposed above the sensor 90 so that the detection member (photoelectric sensor) 90 is not affected by the falling carrot N. Further, by passing the cord 90d of the detection member (photoelectric sensor) 90 through the long hole 90c provided in the plate member 90a, the detection member (photoelectric sensor) 90 is perpendicular to the inclined surface of the pumping conveyance device B along the long hole 90c. It is attached as a configuration in which the vertical position can be changed in the direction so that it can be detected even for carrots N having different sizes depending on the harvest season.
Further, if the detection member (photoelectric sensor) 90, the detection member (photoelectric sensor) cord 90d, and the outlet (not shown) are integrated, the present invention can be applied to different carrot aligning apparatuses.

  When the detection member 90 does not detect the carrot N, the pumping and conveying apparatus B is not operated, and energy waste is suppressed. Further, even if the detection member 90 starts to detect the carrot N, the pumping conveyance device B is not operated unless a certain time (˜7 seconds) elapses thereafter. Moreover, the stop time of the draw-up conveyance device B is variable according to the degree of the carrot N staying.

  By providing the detection member 90 at the conveyance start end side end portion of the receiving portion 74, the carrot N is excessively supplied from the input conveyor S (FIG. 1), and when the carrot N stays on the conveyance start end side of the pumping conveyance device B, The detection member 90 detects the stay of the carrot N, sends a signal to the control device, and stops the input conveyor S for the time set by the control device, so that the carrot N stays at the transport start end side of the pumping transport device B. Therefore, it is possible to prevent the pumping from being carried up and the work efficiency is improved as compared with the conventional method.

  By forming the photoelectric sensor 90 and the power supply device (outlet tap) (not shown) as an integral unit, even if the input device S is a different manufacturer, the outlet of the input device can be plugged into the power supply device. Since it operates, if it already has a dedicated charging device S, a stop / operation switching mechanism for preventing staying can be used without introducing a new charging device S.

FIG. 10 shows a perspective view (FIG. 10 (a)) from the upper right and a perspective view (FIG. 10 (b)) from the upper left of an alignment transport apparatus of another embodiment. In addition to the receiving portion 74, a second receiving portion 92 may be provided on the downstream side in the conveying direction of the receiving portion 74 and immediately below the pressing member 71.
The second receiving portion 92 can prevent the carrot N from being damaged when dropped from the vicinity of the pressing member 71, and can prevent the carrot N from falling along with other carrots N.
In addition, the pressing member 71 can be slid up and down so that the pressing member 71 can cover the upper end portion of the second receiving portion 92.

Further, a cover 93 may be provided between the receiving portion 74 and the second receiving portion 92 so that the carrot N does not jump out. If the cover 93 is made of a transparent and flexible material, the state of conveyance of the carrot N can be visually confirmed, and even if the carrot N falling on contact with the string members 72 and 73 hits the inner surface of the cover, it is not damaged. Because it is configured, the carrot's commercial value is improved.
Maintenance is maintained by making the cover 93 detachable or openable.

FIG. 11 shows a plan view (FIG. 11A) and side views (FIGS. 11B and 11C) of the bottom floor body 96 of the storage hopper 4.
A plurality of plates 97 are connected by a hinge 98 and arranged in a bent shape in a longitudinal section, and the bent bottom floor body 96 can be swung by a cam 99 as shown in FIG. To do. When the cam body 99 touches the bent plate 97 below the bent bottom floor body 96, the plate 97 of the bottom floor body 96 bent downward is bent upward as shown in FIG. 11 (c). The plate 97 bent upward is bent downward.
In this way, the bottom floor body 96 can reliably convey the carrot N from the storage hopper 4 to the pumping and conveying apparatus B.

  As shown in FIGS. 7 and 8, when the return amount of the carrot N is detected by a certain amount (for example, 3 lines / second) or more by the infrared sensors 67, 67 arranged on the inlet side of the pair of feedback shooters 64, 64. Then, it is determined that the transport speed of the pumping transport device B is too fast, and the transport speed is decreased. For the adjustment of the conveyance speed, it is desirable to decelerate by an inverter in multiple stages, for example, at a constant speed (0.005 m / sec). This is because if the transport speed is suddenly reduced, the carrot N being transported may be braked and fall. After that, when the detected amount of carrot N on the inlet side of the feedback shooter 64 returns to less than a certain amount (for example, 3 / second), the transport speed of the pumping transport device B returns to the normal speed.

  Further, a side plate 64a that is the same height as the upper end portion of the storage portion A or longer in the vertical direction than the upper end portion of the storage portion A is provided on the moving end portion side (front side of the machine body) on the outlet side (storage hopper 4 side) of the feedback shooter 64. By doing so, when the carrot N that has moved the feedback shooter 64 (return member) is taken over by the reservoir A, it can be prevented from jumping out of the machine with the momentum of movement, and the crop can be damaged by the impact of falling. The work of picking up the dropped carrot N can be omitted without impairing the commercial value of the crop, and the work efficiency is improved.

  The alignment apparatus of the present invention can be used not only for transporting crops such as root vegetables but also for transporting other crops.
