Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery and equipment technology, specifically to a pruning device for thin-skinned hickory planting. Background Technology

[0002] Thin-shelled pecan trees often develop a tangled and chaotic canopy, blocking direct sunlight and preventing the fruit from receiving sufficient light for proper development and ripening. Therefore, pruning is necessary. Pruning removes excess and unhealthy branches, improving air circulation and light penetration within the canopy, reducing canopy density, and lessening the load on the branches. This promotes normal photosynthesis, increases the rate of nutrient synthesis, and ultimately fosters healthy fruit development.

[0003] Pruning equipment includes electric pruning shears and mechanical pruning shears, both of which are equipped with pruning blades. When installing the blades, tools such as screwdrivers or wrenches are typically used to secure them to the equipment. Screws are usually required to tighten the blades onto the mounting posts or slots of the equipment. This forces growers to spend more time and effort replacing the blades when they wear out or become damaged. This not only increases the difficulty of operation but may also affect work efficiency. Therefore, those skilled in the art provide a pruning device for thin-shelled pecan cultivation to solve the problems mentioned in the background art. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-4 This utility model provides a technical solution:

[0026] A pruning device for thin-shelled pecan cultivation includes:

[0027] Electric telescopic pole 1, with a grab bar 2 at one end of the electric telescopic pole 1, a switch button 3 installed on the grab bar 2, and a support frame 4 installed at the end of the electric telescopic pole 1 away from the grab bar 2;

[0028] The pruning shears include a first handle 5, a second handle 6, a guillotine 7, and a blade 8. The guillotine 7 has a through groove 16, and the blade 8 is engaged in the through groove 16. The first handle 5 and the second handle 6 are rotatably connected at one end. The guillotine 7 is connected to one end of the first handle 5. The second handle 6 has a connecting groove 17 at one end, and one end of the blade 8 is engaged in the connecting groove 17. The end of the first handle 5 away from the guillotine 7 is connected to a support frame 4. The second handle 6 and the blade 8 are connected by a locking mechanism.

[0029] Specifically, the locking mechanism includes a square locking rod 18, a return spring 19, and a connecting block 20. The connecting block 20 is fixedly connected to one end of the second handle 6. The connecting block 20 has an installation groove 21 for the return spring 19 to be installed. The return spring 19 is sleeved on the square locking rod 18. The square locking rod 18 has a limiting plate 22. One end of the return spring 19 is connected to the limiting plate 22. The blade 8 has a locking groove 23. The square locking rod 18 passes through the installation groove 21 and is locked in the locking groove 23. One end of the square locking rod 18 has a pull handle 24.

[0030] When disassembling the blade 8, pull the handle 24 to pull one end of the square locking rod 18 out of the locking groove 23, and then remove one end of the blade 8 from the connecting groove 17.

[0031] When installing the blade 8, pull the handle 24 to engage one end of the blade 8 in the connecting groove 17. Then release the handle 24, and the return spring 19 releases its elastic potential energy. The return spring 19 pushes the limiting plate 22 on the square engaging rod 18, which can engage one end of the square engaging rod 18 in the engaging groove 23 on the blade 8, thus fixing the blade 8 in the connecting groove 17 and fixing the blade 8 to the second handle 6.

[0032] In summary, when it is necessary to disassemble blade 8, operators no longer need to use traditional tools such as wrenches. Operators can easily disassemble and replace blade 8 with simple operations. This not only greatly facilitates the disassembly and replacement of blade 8, but also effectively shortens equipment maintenance time, thereby significantly improving overall work efficiency.

[0033] The electric push rod 9 has its two ends connected to the support frame 4 and one end of the second handle 6 via the first connecting component and the second connecting component, respectively.

[0034] Furthermore, one end of the electric telescopic rod 1 is provided with a first connecting plate 10, and the first connecting plate 10 is connected to the support frame 4 by mounting bolts 11.

[0035] When disassembling the pruning shears from the electric telescopic pole 1, remove the mounting bolts 11, and then separate the support frame 4 from the first connecting plate 10.

[0036] Specifically, the first connecting assembly includes two first side blocks 12 and a rotating block 13. The rotating block 13 is connected to one end of the electric push rod 9. The two first side blocks 12 are fixedly connected to the support frame 4. The rotating block 13 is rotatably connected between the two first side blocks 12. The second connecting assembly includes two second side blocks 14 and a second connecting plate 15. The second connecting plate 15 is connected to the end of the electric push rod 9 away from the rotating block 13. The two second side blocks 14 are fixedly connected to the second connecting plate 15. The end of the second handle 6 away from the blade 8 is rotatably connected between the two second side blocks 14.

[0037] When pruning the branches of the planted thin-skinned hickory trees, the electric telescopic rod 1 is adjusted according to the height of the branches. After adjusting to the appropriate position, the switch button 3 is pressed to control the extension and retraction of the electric push rod 9. The extension and retraction of the electric push rod 9 can drive one end of the second handle 6 to move. The movement of one end of the second handle 6 can drive the blade 8 to move, so that the branch is between the blade 8 and the guillotine 7. The blade 8 moves to prune the branch. When the blade 8 moves into the through groove 16 on the guillotine 7, the pruning of the branch is completed. Compared with the traditional manual pruning method, it not only greatly reduces the labor intensity of the operator, but also significantly improves the convenience of pruning.

[0038] When the electric push rod 9 extends or retracts, one end of the second handle 6 rotates between the two second side blocks 14, and the rotating block 13 rotates between the two first side blocks 12, so that the electric push rod 9 can drive one end of the second handle 6 to move and adjust.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
