Description

Technical Field

[0001] This utility model belongs to the field of forestry logging technology, specifically relating to a high-altitude pruning shears. Background Technology

[0002] During the growth of trees, proper pruning can not only shape a beautiful tree shape, but also promote healthy growth, increase fruit yield (for fruit trees), and enhance the tree's resistance to wind and disease.

[0003] However, when it comes to pruning branches at height, traditional pruning methods often rely on manual operation with extended shears or saws. It is difficult to accurately position the pruning location when using manual tools, especially when it is necessary to precisely control the pruning at a specific distance above the bud (such as 2-3 cm above the bud). During the pruning process, the pruning shears are often moved accidentally, resulting in pruning in the wrong position on the outside of the branch, leading to incorrect pruning. Utility Model Content

[0004] The purpose of this invention is to provide a high-altitude pruning shear that can stably prune at a position 2-3 cm above the bud, reducing pruning errors during the branch pruning process.

[0005] The specific technical solution adopted by this utility model is as follows:

[0006] A type of high-altitude pruning shears includes a handle, a connecting bracket, a branch clamping and positioning mechanism, branch pruning shears, and a controller, wherein the branch clamping and positioning mechanism and the branch pruning shears are electrically connected to the controller;

[0007] The connecting bracket is fixedly connected to the upper end of the handle, and the branch clamping and positioning mechanism and the branch pruning shears are both fixedly connected to the connecting bracket.

[0008] Furthermore, the branch clamping and positioning mechanism includes a C-shaped plate fixedly connected to the connecting bracket, a pressure plate vertically slidably connected inside the C-shaped plate, and an electric vertical moving mechanism fixedly connected to the upper end of the C-shaped plate, the electric vertical moving mechanism and the pressure plate being fixedly connected.

[0009] Furthermore, the compression plate is a V-shaped plate.

[0010] Furthermore, the electric vertical moving mechanism includes a storage shell fixedly connected to the upper side of the C-shaped plate. An electromagnet is fixedly connected to the upper end of the storage shell. A slider is slidably connected to the storage shell and located below the electromagnet. The lower end of the slider is fixedly connected to a pressure plate. A magnet is fixedly connected to the upper end of the slider. When the electromagnet is energized, it and the magnet repel each other magnetically. A tension spring is also fixedly connected to the upper end of the slider. The upper end of the tension spring is fixedly connected to the inner wall of the upper side of the pressure plate.

[0011] Furthermore, the pruning shears include a mounting plate fixedly connected to a connecting bracket. The mounting plate has two sliding grooves, and a movable block is slidably connected inside each of the two sliding grooves. A shear body is fixedly connected to each of the two movable blocks. A screw threadedly connected to the movable block is rotatably connected inside each of the two sliding grooves. Two drive motors are fixedly connected to the end of the mounting plate, and the two drive motors are respectively fixedly connected to the two screws.

[0012] Furthermore, the included angle between the groove axis and the slider axis is 45°.

[0013] Furthermore, a sleeve is fixedly connected to the upper end of the grip, and a rotating rod is rotatably connected inside the sleeve. One end of the rotating rod is fixedly connected to a connecting bracket. A spiral spring is sleeved on the outside of the sleeve and the rotating rod. One end of the spiral spring is fixedly connected to the sleeve, and the other end of the spiral spring is fixedly connected to the connecting bracket.

[0014] The technical effects achieved by this utility model are as follows:

Detailed Implementation

[0022] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0023] like Figures 1-4 As shown, a high-altitude pruning shears includes a handle 1, a connecting bracket 2, a branch clamping and positioning mechanism 3, branch pruning shears 4, and a controller;

[0024] The controller includes a control button fixedly connected to the lower end of the handle 1. The control button is electrically connected to the control host, and the control host is electrically connected to the battery. At this time, the branch clamping and positioning mechanism 3 and the branch pruning shears 4 are both electrically connected to the control host. At this time, the branch clamping and positioning mechanism 3 and the branch pruning shears 4 can be controlled by the control button.

[0025] The connecting bracket 2 is fixedly connected to the upper end of the handle 1. The branch clamping and positioning mechanism 3 and the branch pruning shears 4 are both fixedly connected to the connecting bracket 2. At this time, holding the handle 1 can drive the branch clamping and positioning mechanism 3 and the branch pruning shears 4 to move between branches in the air. When the branch clamping and positioning mechanism 3 is clamped on the outside of the branch, the branch pruning shears 4 can be positioned by the branch clamping and positioning mechanism 3 clamped on the outside of the branch. Then, the branch pruning shears 4 can be started to cut the branch and complete the pruning of the branch.

[0026] Furthermore, during the pruning process, since the distance between the branch clamping and positioning mechanism 3 and the branch pruning shears 4 is fixed, the branch clamping and positioning mechanism 3 is positioned at a specific position outside the bud of the branch cut. Then, the branch pruning shears 4 can be used to prune at a position 2-3 cm above the bud. This allows the branch to be pruned after the branch pruning shears 4 are stably positioned, thus ensuring that the pruning is carried out stably at a position 2-3 cm above the bud and reducing the occurrence of incorrect pruning during the branch pruning process.

[0027] like Figure 1 and Figure 3As shown, the branch clamping and positioning mechanism 3 includes a C-shaped plate 8 fixedly connected to the connecting bracket 2. A pressure plate 9 is vertically slidably connected inside the C-shaped plate 8. An electric vertical moving mechanism is fixedly connected to the upper end of the C-shaped plate 8. The electric vertical moving mechanism and the pressure plate 9 are fixedly connected. At this time, by starting the electric vertical moving mechanism, the pressure plate 9 can be moved, so that the C-shaped plate 8 and the pressure plate 9 clamp the outside of the branch, thus completing the positioning of the branch clamping and positioning mechanism 3.

[0028] Here, the tablet press 9 can be a flat plate. In this technical solution, in order to accurately position the middle position of the tablet press 9 and the branches, the tablet press 9 is selected as a V-shaped plate.

[0029] like Figure 3 As shown, the electric vertical moving mechanism includes a storage shell 10 fixedly connected to the upper side of the C-shaped plate 8. An electromagnet 12 is fixedly connected to the upper end of the storage shell 10. The electromagnet 12 is electrically connected to the control host. A slider 11 is slidably connected inside the storage shell 10 and below the electromagnet 12. The lower end of the slider 11 is fixedly connected to the pressure plate 9. A magnet 13 is fixedly connected to the upper end of the slider 11. When the electromagnet 12 is energized, it and the magnet 13 repel each other magnetically. A tension spring 14 is also fixedly connected to the upper end of the slider 11. The upper end of the tension spring 14 is fixedly connected to the inner wall of the upper side of the pressure plate 9. At this time, the tension of the tension spring 14 can pull the slider 11 upward, thereby adjusting the movement of the clamping plate slide groove 19 in a relatively simple way.

[0030] like Figure 1 and Figure 4 As shown, the tree branch pruning shears 4 include a mounting plate 15 fixedly connected to the connecting bracket 2. The mounting plate 15 has two sliding grooves 19. The interior of each sliding groove 19 is slidably connected to a moving block 16. Each moving block 16 is fixedly connected to a shear body 17. The opposite side of the two shear bodies 17 is the blade. At this time, the tree branch between the two shear bodies 17 can be cut by the shearing force between the two shear bodies 17.

[0031] In order to move the scissor body 17, the interior of each of the two slides 19 is rotatably connected with a screw threaded to the moving block 16. The end of the mounting plate 15 is fixedly connected to two drive motors 18, which are respectively fixedly connected to the two screws. The drive motors 18 are electrically connected to the control host. At this time, the scissor body 17 can be moved by starting the drive motors 18.

[0032] The included angle between the axis of the slide groove 19 and the axis of the slider 11 is 45°, so that when the branch clamping and positioning mechanism 3 is clamped on the outside of the branch, the scissor body 17 and the branch can maintain an included angle of 45°.

[0033] like Figures 1-2As shown, a sleeve 5 can be fixedly connected to the upper end of the grip 1. A rotating rod 6 is rotatably connected inside the sleeve 5. One end of the rotating rod 6 is fixedly connected to the connecting bracket 2. At this time, the tree branch clamping and positioning mechanism 3 can be adapted to the tree branch after being fixed through the rotatable connecting bracket 2.

[0034] To maintain the initial angle of the connecting bracket 2, a spiral spring 7 is sleeved on the outside of the sleeve 5 and the rotating rod 6. One end of the spiral spring 7 is fixedly connected to the sleeve 5, and the other end of the spiral spring 7 is fixedly connected to the connecting bracket 2. At this time, the connecting bracket 2 can be initially positioned by the rotating rod 6.

[0035] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
