Abstract
Description
Technical Field
[0001] This utility model relates to the field of walnut harvesting equipment technology, and in particular to an integrated walnut picking and collecting device. Background Technology
[0002] Currently, the traditional method for harvesting walnuts after they mature is to knock the branches to let the walnuts fall naturally. Then, the walnuts on the ground are picked up. This traditional method relies heavily on manual labor, which is time-consuming, labor-intensive, and inefficient. Currently, cage-like rolling walnut-collecting tools have appeared on the market. By pushing the harvesting cage on the ground, the walnuts are compressed and deformed by the cage walls and then squeezed into the cage. However, once the cage is full, the walnuts must be manually removed. These walnut-collecting cages generally have a small capacity, allowing only a small number of walnuts to be collected at a time. When collecting larger quantities of walnuts, the process needs to be repeated, resulting in a slow collection speed. Therefore, an integrated walnut-collecting device needs to be developed. Utility Model Content
[0003] The purpose of this utility model is to provide an integrated walnut picking and collecting device to solve the technical problems mentioned in the background art.
[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0005] This utility model discloses an integrated walnut picking and collecting device, comprising a frame with two sets of wheels symmetrically arranged on both sides of the frame, and a drive motor for rotating each wheel is installed inside the frame. A picking roller, a conveyor belt, a transfer drum, and a collection box are sequentially arranged on the frame. Multiple sets of clamping claws are evenly spaced along the axial direction of the picking roller, with each set of clamping claws evenly arranged circumferentially around the picking roller. The conveyor belt is inclined upwards away from the picking roller, with its lower end close to the picking roller. A drive mechanism for the conveyor belt is located on the outer side of the frame. The first motor is driven; one end of the transfer cylinder is located below the upper end of the conveyor belt and has an inlet hopper connected to its interior at the upper part; the other end of the transfer cylinder is located above the collection box and has an outlet hopper connected to its interior at the bottom; a rotating shaft is rotatably arranged in the middle of the transfer cylinder and a spiral blade is fixedly wound on the rotating shaft; a second motor for driving the rotating shaft to rotate is arranged on the outer side of the end of the transfer cylinder near the collection box; an elongated dust leakage hole is opened at the bottom of the part of the transfer cylinder located between the conveyor belt and the collection box, and a screen is fixedly arranged on the dust leakage hole.
[0006] Furthermore, the outer peripheral wall of the pickup roller is provided with a sliding groove at a position corresponding to each of the clamping claws, and each of the clamping claws is slidably disposed in the corresponding sliding groove.
[0007] Furthermore, the pickup roller has an annular cavity inside, which is connected to each of the slide grooves. The outer peripheral wall of the annular cavity is fixedly provided with mounting plates at the two ends of each slide groove. A slide rod is fixedly provided between each pair of opposite mounting plates. Each gripping claw extends into the interior of the annular cavity and is fixedly provided with a sliding sleeve that slides in cooperation with the corresponding slide rod. A spring is sleeved on each slide rod at the two ends of the sliding sleeve between the two mounting plates.
[0008] Furthermore, a shield is fixedly installed inside the vehicle frame above the lower end of the conveyor belt.
[0009] Furthermore, a plurality of levers are fixedly arranged at even intervals on the upper end of the barrier plate, and each lever is located in the middle of two adjacent sets of clamping claws.
[0010] Furthermore, the transfer cylinder is inclined upward in a direction away from the conveyor belt, and the outer wall of the transfer cylinder is fixedly connected to the inner wall of the frame through two pairs of support plates.
[0011] Compared with the prior art, the beneficial technical effects of this utility model are as follows:
[0012] When the frame of this invention moves, the picking roller rolls on the ground and clamps the walnuts on the ground with adjacent gripping claws, thus completing the picking operation. The gripping claws holding the walnuts move with the picking roller and pass the positions of the levers. The levers then dislodge the walnuts from the gripping claws, and they fall onto the conveyor belt under gravity. The conveyor belt and transfer drum successively transport and transfer the walnuts, and they fall from the outlet hopper into the collection box, thus completing the collection operation. This invention can automatically pick up and collect walnuts on the ground, reducing manual labor in the walnut harvesting process and effectively improving work efficiency.
[0013] Furthermore, during the transport of walnuts inside the transfer cylinder, the rotating spiral blades will tumble them, and the dust and other impurities mixed inside the walnuts will fall through the screen at the bottom of the transfer cylinder, thus completing automatic dust removal.

[0020] like Figures 1-4 As shown, an integrated walnut picking and collecting device includes a frame 1. Two sets of wheels 2 are symmetrically and rotatably mounted on both sides of the frame 1, and a drive motor (not shown in the figure) for driving the wheels to rotate is installed inside the frame 1. Picking rollers 4, conveyor belts 5, transfer cylinders 6, and collection boxes 7 are sequentially mounted on the frame 1.
[0021] The pickup roller 4 is equipped with multiple sets of clamping claws 8 evenly spaced along the axial direction, and the multiple clamping claws 8 of each set are evenly arranged along the circumference of the pickup roller 4. The outer peripheral wall of the pickup roller 4 is provided with a sliding groove 9 at a position corresponding to each clamping claw 8, and each clamping claw 8 is slidably installed in the corresponding sliding groove 9.
[0022] In this embodiment, the pickup roller 4 has an annular cavity 10 inside, which is connected to each of the sliding grooves 9. Mounting plates 11 are fixedly installed on the outer peripheral wall of the annular cavity 10 at both ends of each sliding groove 9. Sliding rods 12 are fixedly installed between each pair of opposite mounting plates 11. Each gripping claw 8 extends into the annular cavity 10 and is fixedly fitted with a sliding sleeve 13 that slides in cooperation with the corresponding sliding rod 12. Springs 14 are fitted onto the ends of each sliding rod 12 between the sliding sleeve 13 and the two mounting plates 11. Through this arrangement, each gripping claw can slide freely in the axial direction of the pickup roller 4, thereby facilitating the gripping of walnuts on the ground by adjacent gripping claws.
[0023] The conveyor belt 5 is inclined upward in a direction away from the pickup roller 4, and the lower end of the conveyor belt 5 is close to the pickup roller 4. A first motor 15 for driving the conveyor belt 5 is installed on the outside of the frame 1.
[0024] Inside the frame 1, a shielding plate 16 is fixedly installed above the lower end of the conveyor belt 5. Multiple levers 17 are fixedly arranged at even intervals on the upper end of the shielding plate 16, and each lever 17 is located in the middle of two adjacent sets of clamping claws 8.
[0025] The transfer cylinder 6 is inclined upward in a direction away from the conveyor belt 5, and the outer wall of the transfer cylinder 6 is fixedly connected to the inner wall of the frame 1 through two pairs of support plates 18.
[0026] One end of the transfer cylinder 6 is located below the upper end of the conveyor belt 5, and an inlet hopper 19 communicating with its interior is installed on its upper part. The other end of the transfer cylinder 6 is located above the collection box 7, and an outlet hopper 20 communicating with its interior is installed at its bottom. A rotating shaft 21 is rotatably installed in the middle of the interior of the transfer cylinder 6, and a spiral blade 22 is fixedly wound on the rotating shaft 21. A second motor 23 for driving the rotating shaft 21 to rotate is installed on the outer side of the end of the transfer cylinder 6 near the collection box 7. An elongated dust leakage hole is opened at the bottom of the part of the transfer cylinder 6 located between the conveyor belt 5 and the collection box 7, and a screen 24 is fixedly installed on the dust leakage hole.
[0027] The operation process of this utility model is as follows:
[0028] As the wheels rotate, the frame moves across the ground. The pickup roller at the front of the frame rolls along the ground, gripping walnuts with adjacent clamping claws. These claws move with the pickup roller and pass the levers. When the levers reach the positions of the levers, they actuate the walnuts held by their corresponding adjacent claws, causing the walnuts to detach and fall onto the conveyor belt under gravity. Once the walnuts reach the top of the conveyor belt, they fall into the feed hopper under gravity and enter the transfer drum. A second motor drives a rotating shaft, and the rotating spiral blades convey the walnuts to the output hopper in a spiral manner, from where they fall into the collection box. Furthermore, during the transfer process, the spiral blades tumble the walnuts, causing dust and other impurities mixed inside to fall through the screen at the bottom of the transfer drum, thus achieving automatic dust removal.
[0029] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
