Description

Technical Field

[0001] This utility model relates to the field of walnut cultivation, and in particular to a pruning device for walnut cultivation. Background Technology

[0002] To control the growth of trees, activate the growth of main branches, and ensure higher fruit quality and greater yield, walnut trees need to be pruned during planting. Smaller branches are pruned with pruning shears, while thicker branches require tools such as saws.

[0003] A search revealed Chinese Patent Publication No. CN220830908U, which discloses a pruning device for walnut cultivation, belonging to the field of walnut planting technology. This pruning device includes a sleeve, a telescopic rod, a pruning assembly, and a limiting assembly. The telescopic rod is slidably installed inside the sleeve. The pruning assembly includes a connecting seat and pruning shears. The connecting seat is fixedly installed at one end of the telescopic rod, and the pruning shears are symmetrically slidably installed on the side wall of the connecting seat. A positioning groove is formed on the surface of the pruning shears. The limiting assembly includes a fixed seat, an eccentric wheel, and a limiting block. The fixed seat is fixedly installed at one end of the sleeve, and the eccentric wheel is rotatably installed inside the fixed seat. This invention, by setting up the pruning assembly, inserts the walnut branch to be pruned between two pruning shears and places it in the positioning groove. A motor drives a bidirectional lead screw to rotate, thereby driving two threaded blocks to move closer together, which in turn moves the two pruning shears closer together to prune the walnut branch. This effectively prevents the walnut branch from slipping off the pruning shears during pruning, improving pruning efficiency.

[0004] Although the above-mentioned device can adjust its length by setting a limiting component, its stability is not high due to the cooperation between components such as tension spring limiting blocks. Moreover, its adjustment position is set in the middle, so when adjustment is needed, the user can only retract the device to make the adjustment. However, after retracting, the user cannot intuitively understand the actual length adjustment needs, which is inconvenient and impractical. Therefore, a pruning device for walnut planting is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a pruning device for walnut planting, which aims to improve the stability of the existing technology where the adjustment components are not very stable due to the cooperation between components such as tension spring limit blocks. Furthermore, the adjustment position is set in the middle, and when adjustment is needed, the user can only retract the device to make the adjustment. However, after retraction, it is not possible to intuitively understand the actual length adjustment requirements, which is inconvenient for adjustment.

[0014] The adjustment assembly also includes a mounting block, the control rod is connected to the mounting block through and rotatably, the mounting block is fixedly connected to the saw, and the upper and lower parts of the mounting block are fixedly connected to fixing blocks.

[0015] As a further description of the above technical solution:

[0031] 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.

[0032] Reference Figure 1 - Figure 3 This utility model provides an embodiment of a pruning device for walnut planting, comprising a hollow rod 1 for connecting various components. An extension rod 2 is slidably connected to the middle of the hollow rod 1 for cooperating with the hollow rod 1 to adjust the height of a saw 5. A control sleeve 4 is rotatably connected to the rear end of the hollow rod 1 for controlling the rotation of a screw 41. An adjustment component 3 is provided at the front end of the extension rod 2 for cooperating with adjusting the angle of the saw 5. The saw 5, which can be an electric saw, is provided at the front of the adjustment component 3, and a switch is provided at the top. Slide grooves 11 are provided on both the left and right sides of the inner wall of the hollow rod 1 for cooperating with the connection and movement of sliders 21. Slides 21 are fixedly connected to the left and right sides of the rear of the extension rod 2 for cooperating with the slide grooves 11 to control the movement direction of the extension rod 2, so that it can only move back and forth. The sliders 21 are slidably connected to the slide grooves 11. A screw 41 is fixedly connected to the middle of the control sleeve 4 for cooperating with adjusting the position of the extension rod 2. The screw 41 passes through and is threadedly connected to the extension rod 2.

[0033] Furthermore, a limit ring 42 is fixedly connected to the inner wall of the control sleeve 4, and a limit groove 12 is opened on the rear outer wall of the empty rod 1. The limit ring 42 is rotatably connected to the limit groove 12, which is used to prevent the control sleeve 4 from separating from the empty rod 1.

[0034] like Figure 4 - Figure 5 As shown, the adjustment assembly 3 includes a mounting bracket 31, which is used to connect various components. The mounting bracket 31 is fixedly connected to the extension rod 2. A control rod 32 is rotatably connected through the middle of the mounting bracket 31. The upper and lower parts of its outer wall are respectively provided with threads in opposite directions. The upper and lower parts of the control rod 32 are both threadedly connected to limit blocks 33, which are used to cooperate with the fixing block 35 to adjust and fix the angle of the mounting block 34, thereby adjusting the angle of the saw 5. The adjustment assembly 3 also includes a mounting block 34, which is used to connect the saw 5. The control rod 32 is rotatably connected to the mounting block 34. The mounting block 34 is fixedly connected to the saw 5. The upper and lower parts of the mounting block 34 are fixedly connected to the fixing blocks 35, which are used to adjust the angle of the mounting block 34.

[0035] Furthermore, each of the two limiting blocks 33 has a first protruding tooth 331 fixedly connected to one side close to each other, and there are multiple such teeth. These teeth are used to engage with the fixing block 35. Each of the two fixing blocks 35 has a second protruding tooth 351 fixedly connected to one side far from each other, and there are multiple such teeth. These teeth are used to engage with the limiting blocks 33 to achieve the purpose of angle fixation. The fixing blocks 35 and the limiting blocks 33 are engaged. The inner wall of the mounting bracket 31 is fixedly connected with a limiting rod 311, and there are multiple such rods. These rods are used to restrict the movement direction of the limiting blocks 33, so that they can only move up and down. The limiting rods 311 and the limiting blocks 33 are connected through and slidably.

[0036] Working principle: When it is necessary to adjust the height of saw 5, rotate control sleeve 4. Control sleeve 4 will drive screw 41 fixed to it to rotate. Extension rod 2 connected to screw 41 will be driven accordingly. Since slider 21 is provided on extension rod 2, and slider 21 only slides in limit groove 12, when screw 41 rotates, extension rod 2 will slide in empty rod 1 according to the rotation direction of screw 41, thereby adjusting the height of saw 5. When the height of saw 5 is adjusted appropriately, simply stop rotating control sleeve 4.

[0037] When the angle of saw 5 needs to be adjusted, first rotate the control lever 32. The control lever 32 will then drive the two limit blocks 33 to move away from the fixed block 35. At this time, the mounting block 34 can rotate. After the mounting block 34 drives saw 5 to the appropriate position, the control lever 32 can be rotated in the opposite direction to control the two limit blocks 33 to fix the fixed blocks 35 on both sides of the mounting block 34, so that the limit blocks 33 and the fixed blocks 35 mesh, thereby fixing the position of the mounting block 34.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
