[0030] In the prior art, negative pressure is generated by a centrifugal fan to pick up red dates. However, due to the large suction force of the fan, it is easy for the red dates to violently contact with the screen plate, causing the surface of the red dates to break. At the same time, the existing screen plate is usually fixed, so some red dates are not easy to roll off the screen plate, resulting in the red dates being in contact with the screen plate for too long. The friction between the red dates and the screen plate easily causes the red dates to break, affecting the quality of the red dates. Therefore, after research, a pneumatic red date picking device that can reduce the rate of date skin damage is provided. When in use, the red dates and impurities are sorted by the sorting plate, so that the impurities fall on the inclined plate, and the cam is rotated by the rotating rod, so that the cam strikes the sorting plate, which not only accelerates the separation of the red dates and impurities, but also allows the red dates to quickly enter the box, reducing the friction between the red dates and the sorting plate, reducing the rate of red dates breaking, and combining the elastic buffer of the spring and the buffer of the buffer plate to reduce the contact force between the red dates and the sorting plate, thereby solving the above defects.
[0031] In conjunction with the accompanying drawings, some embodiments of the present invention are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.
[0032] Please refer to Figures 1 to 8 The embodiment of the utility model provides an air-suction red date picking device which can reduce the damage rate of the date skin, including a picking machine 1, a box body 2 is arranged on the upper side of the picking machine 1, a fan 5 is installed on the upper side of the box body 2, an air inlet of the fan 5 is connected with a suction pipe 4, the suction pipe 4 runs through a sorting box 3 on one side of the box body 2, an air shut-off device 43 is installed at the discharge port of the suction pipe 4, a collecting cover 41 is arranged at the suction port of the suction pipe 4, the negative pressure generated after the fan 5 is started makes the suction pipe 4 pick up the red dates on the ground, and the collecting cover 41 expands the area for sucking the dates, and a slag discharge pipe 51 is connected to one side of the fan 5 for discharging tiny impurities that enter.
[0033] Among them, one end of the picking machine 1 is hinged to the third cylinder 42, and when the third cylinder 42 pushes the straw 4, the date sucking position of the straw 4 can be changed.
[0034] A chute 31 is symmetrically provided on one side of the sorting box 3, and a slider 451 is slidably arranged in the chute 31. One side of the slider 451 is connected to a sorting plate 45, which is arranged at an angle and is used to separate red dates from impurities. One end of the sorting plate 45 is hinged inside the box body 2, and springs 32 connected to the sorting plate 45 are arranged at the upper and lower ends of the chute 31. When the red dates fall from the air lock 43, they are buffered by a buffer plate 44 arranged on one side of the discharge port of the air lock 43 to reduce the falling speed of the red dates, so that the red dates are not easily broken when they contact the sorting plate 45. The gravity of the red dates causes the sorting plate 45 to squeeze the lower spring 32 and stretch the upper spring 32. Through the elastic action of the spring 32, the falling force of the red dates is further buffered to ensure the integrity of the red dates.
[0035] Furthermore, a rotating rod 46 is rotatably arranged in the sorting box 3, and a cam 47 is connected to the rotating rod 46. The cam 47 is located on the lower side of the sorting plate 45. The rotating rod 46 is driven by a motor. When the rotating rod 46 rotates with the cam 47, the cam 47 strikes the sorting plate 45, which not only accelerates the separation of the red dates from impurities, but also promotes the red dates to quickly enter the box body 2, reduces the friction between the red dates and the sorting plate 45, and prevents the red dates from breaking.
[0036] An inclined plate 33 is provided at the bottom of the sorting box 3 , one end of which extends into the impurity discharge port 23 opened at one side of the box body 2 , and impurities filtered by the sorting plate 45 enter the box body 2 through the inclined inclined plate 33 .
[0037] In order to discharge impurities, a partition plate 21 is provided in the box body 2, and a date opening 22 is provided on the upper side of the partition plate 21. One end of the sorting plate 45 extends into the date opening 22, so that the red dates dropped from the sorting plate 45 enter the box body 2 from the date opening 22. At the same time, an impurity discharge channel is formed between the partition plate 21 and the side wall of the box body 2, and a material discharge port 24 is provided at the bottom of the impurity discharge channel. After the impurities enter the impurity discharge channel, they are discharged from the box body 2 through the material discharge port 24.
[0038] In addition, in order to reduce the breakage of the sorted red dates during collection, a placement plate 28 is provided inside the box body 2 to form a material receiving channel between the placement plate 28 and the partition plate 21. A plurality of storage boxes 6 are arranged in sequence on the upper side of the placement plate 28 to store the sorted red dates. A through hole 283 is provided on one side of the placement plate 28 to allow the storage boxes 6 to enter the material receiving channel through the through hole 283.
[0039] Adjustment grooves 26 are provided on both sides of the partition plate 21, and a moving block 291 is slidably set in the adjustment groove 26. One side of the moving block 291 is connected to a receiving plate 29. The receiving plate 29 is located in the material receiving channel to support the storage box 6 and assist the storage box 6 in receiving red dates. A screw rod 27 is rotatably set in one of the adjustment grooves 26, and the moving block 291 is threadedly connected to the screw rod 27. The screw rod 27 is driven by a motor installed at the bottom of the picking machine 1, so that the moving block 291 automatically moves with the receiving plate 29, so that the receiving plate 29 supports the storage box 6 without red dates, shortens the falling distance of the red dates, reduces the collision force between the red dates, and prevents the red dates from breaking. At the same time, the receiving plate 29 can bring the storage box 6 full of red dates down and stably deliver the storage box 6 to the bottom of the box body 2.
[0040] In order to allow the storage boxes 6 to enter the receiving plate 29 in sequence, a first cylinder 281 is installed on one side of the placement plate 28, and the piston end of the first cylinder 281 is connected to the U-shaped plate 282. The storage box 6 is located in the U-shaped plate 282. The first cylinder 281 moves with the U-shaped plate 282 to push the storage box 6 onto the receiving plate 29.
[0041] Secondly, a second cylinder 292 is installed on one side of the receiving plate 29, and the piston end of the second cylinder 292 is connected to the push plate 293. The second cylinder 292 is located in the opening 25 opened in the partition plate 21. When the receiving plate 29 is lowered, the second cylinder 292 moves with the push plate 293, and the push plate 293 pushes the storage box 6 out of the receiving plate 29.
[0042] In summary, the air-suction red dates picking device which can reduce the breakage rate of the date skin of the utility model embodiment has the following working principle: after the picking machine 1 moves, the fan 5 starts to generate negative pressure, so that the suction tube 4 picks up the red dates on the ground, and the red dates fall onto the sorting plate 45 through the buffer plate 44, and the rotating rod 46 rotates with the cam 47 to knock the sorting plate 45, so that the red dates are separated and quickly enter the lower date opening 22. At this time, the impurities are guided to the lower material opening 24 through the inclined plate 33 for removal, and the red dates enter the storage box 6 supported by the receiving plate 29. As the moving block 291 slides in the adjusting groove 26, the receiving plate 29 descends with the storage box 6, and the storage box 6 is pushed to the bottom of the box body 2 by the pushing plate 293. When the receiving plate 29 is reset, the U-shaped plate 282 pushes the new storage box 6 into the receiving plate 29 for receiving.
[0043] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
