Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery and equipment technology, and in particular to a small orchard branch picking machine. Background Technology

[0002] my country is a major fruit producer. During fruit cultivation, orchards prune fruit trees at certain times each year, generating a large amount of pruning residue. Currently, the disposal of this residue is often a problem rather than an opportunity to increase fruit farmers' income. Common methods include collecting and burning the branches, piling them up in fields or roadsides, or burying them on-site. These methods damage the environment and pose safety hazards. To solve the environmental problems caused by pruning, specialized machinery needs to be developed to process the pruned branches. After being chopped, the pruned branches are easier to transport, and they themselves are a good source of biomass energy. Collecting and processing them can bring economic benefits to fruit farmers.

[0003] An existing patent (publication number: CN218353331U) discloses a small orchard branch picking machine, which includes at least a collection box, a transmission system, a frame, a gathering device, a picking and feeding device, a chopping device, a throwing device, and a scraper conveying device. In the process of implementing this solution, the inventors discovered the following problems in the existing technology that have not been adequately addressed: 1. Some branches fall under the trunk, and the device is difficult to move to the underside of the branches for picking, thus requiring manual removal of the branches beforehand, which is quite troublesome.

[0020] In one embodiment, such as Figure 1-4 As shown, a small orchard branch picking machine includes a picking machine body 1. A connecting box 2 is fixedly connected to the right side of the outer wall of the picking machine body 1. Threaded rods 3 are symmetrically connected to the front side of the inner wall of the connecting box 2 via bearings. The threads on the surfaces of the two threaded rods 3 are in opposite directions. Movable blocks 4 are threadedly connected to the middle of the surfaces of both threaded rods 3. Connecting plates 5 are fixedly connected to the bottom surfaces of both movable blocks 4. First electric telescopic rods 6 are symmetrically fixedly connected to the opposite sides of the bottom surfaces of the two connecting plates 5. Mounting blocks 7 are fixedly connected to the lower ends of the two symmetrical first electric telescopic rods 6. Several gripping teeth 8 are fixedly connected to the bottom surface of the mounting block 7. The gripping teeth 8 extend from the left... The components are arranged linearly from right to left. The rear side of the connecting box 2 has symmetrical through holes. The rear ends of the two threaded rods 3 are respectively bearing connected in the adjacent through holes and extend to the outside of the rear side of the connecting box 2. A support plate 9 is fixedly connected to the rear side of the outer wall of the connecting box 2 near the front side. A motor 10 is fixedly connected to the top surface of the support plate 9. The rear end face of the front threaded rod 3 is fixedly connected to the shaft of the motor 10. The upper ends of several gripping teeth 8 on the same side are movably sleeved with a cleaning plate 11. A second electric telescopic rod 12 is fixedly sleeved in the middle of the connecting plate 5. A connecting block 13 is fixedly connected to the lower end of the second electric telescopic rod 12. The connecting block 13 is fixedly connected to the cleaning plate 11.

[0021] To improve the stability between the connecting plate 5 and the movable block 4 and to prevent breakage between them, fixing blocks 14 are fixedly connected to the front and rear sides of the bottom surface of the connecting box 2. A reinforcing rod 15 is movably sleeved in the middle of each fixing block 14. A fixing plate 16 is fixedly connected to the side of the top surface of the connecting plate 5 away from the movable block 4. The end faces of the two sides of the reinforcing rod 15 are fixedly connected to the adjacent fixing plate 16 and the facing surfaces of the movable block 4, respectively.

[0022] In order to allow the lower side of the movable block 4 to extend to the outside of the connecting box 2 and to restrict the movable block 4 so that it does not rotate with the threaded rod 3, movable openings 17 are provided on the left and right sides of the bottom of the connecting box 2. The bottoms of the two movable blocks 4 are slidably connected in the adjacent movable openings 17 and extend to the outside of the bottom of the connecting box 2.

[0023] In order to connect the device to the tractor, a frame 18 is fixedly connected to the middle of the right side of the outer wall of the connecting box 2, and a traction frame 19 is hinged on the frame 18.

[0024] In order to enable the two threaded rods 3 to rotate synchronously, sprockets 20 are fixedly sleeved on the rear ends of the surfaces of the two threaded rods 3, and chains 21 are sleeved on the two sprockets 20.

[0025] To facilitate the control of the operation of the first electric telescopic pole 6, the motor 10, and the second electric telescopic pole 12, an electrical control system is installed on the connecting box 2. The electrical control system is electrically connected to the first electric telescopic pole 6, the motor 10, and the second electric telescopic pole 12.

[0026] Working Principle: When using this utility model, the device is first attached to the corresponding agricultural tractor via the towing frame 19, and the electronic control system is connected to the controller on the tractor. Then, the tractor drags the pickup body 1. When the tractor is driving next to a tree and finds fallen branches under the tree, the motor 10 is started. The motor 10 drives the right threaded rod 3 to rotate. The right threaded rod 3, through the cooperation of the sprocket 20 and the chain 21, drives the threaded rods 3 on both sides to rotate synchronously. The rotation of the threaded rod 3 causes the two movable blocks 4 to move apart. The movable blocks 4 drive the connecting plate 5 to move, the connecting plate 5 drives the first electric telescopic rod 6 to move, and the first electric telescopic rod 6 drives the mounting block 7 to move away from the connecting box 2, thereby moving the gripping teeth 8 to the top of the branches under the tree. Then, the first electric telescopic rod 6 pushes the mounting block 7 down, and the mounting block 7 drives the gripping teeth 8 down, so that the gripping teeth 8 cover the branches inside. When the motor shaft of motor 10 reverses, the mounting block 7 moves closer to the connecting box 2. The gripping teeth 8 scrape the branches on the ground, moving them to the lower side of the connecting box 2. Then, the tractor pulls the pickup machine body 1 to move, allowing the pickup machine body 1 to process the branches. In this way, the device can automatically clear the branches under the tree to the lower side of the connecting box 2, placing the branches in front of the pickup machine body 1 for easy processing. There is no need for manual clearing of branches under the tree trunk in advance, reducing the workload of workers and improving the practicality of the device. After the gripping teeth 8 scrapes the branches to the lower side of the connecting box 2, the second electric telescopic rod 12 can be activated. The second electric telescopic rod 12 pushes the connecting block 13 down, and the connecting block 13 pushes the cleaning plate 11 down. The descent of the cleaning plate 11 can scrape off the branches stuck on the gripping teeth 8, thus preventing the branches from getting stuck on the gripping teeth 8 and being unable to be processed by the pickup machine body 1.

[0027] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0028] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
