[0002] In the process of modern forestry maintenance and management, tree pruning is an important and indispensable task. Traditional tree pruning methods mainly rely on manual operation using scissors, saws and other tools. This method is not only inefficient and labor-intensive, but also has great safety hazards. Especially when pruning forestry trees, workers often need to climb up the trees to work, which not only increases the difficulty of work, but also easily causes safety accidents.

[0021] like Figures 1 to 4 As shown, a protective cover 105 is fixedly installed on one side of the support frame 107, and the protective cover 105 is provided to protect the main tire 104 and the engine 102. Side brackets 201 are symmetrically installed on both sides of the support frame 107, and a rotating frame 202 is rotatably installed on the side bracket 201. A clamping torsion spring 200 is fixedly installed on the rotating frame 202, and the other end of the clamping torsion spring 200 is fixedly installed on the side bracket 201. A clamping sub-wheel 203 is rotatably installed on the rotating frame 202, and the clamping sub-wheel 203 and the main tire 104 are distributed in a triangle. The symmetrically arranged clamping sub-wheel 203 can cooperate with the main tire 104 to clamp the tree trunk 101.

[0022] like Figures 1 to 5As shown, a side cutting plate 208 is slidably installed on the side of the side bracket 201 close to the tree trunk 101, and the side cutting plate 208 is arc-shaped. One end of the side cutting plate 208 is provided with a cutting edge, and a plurality of side springs 209 are fixedly installed on the side cutting plate 208. The other end of the side spring 209 is fixedly connected to the side bracket 201. A handle bracket 204 is fixedly installed on the rotating frame 202, and a handle ring 205 is fixedly installed on the end of the handle bracket 204 away from the side bracket 201. A rotating cutting plate 207 is slidably installed on the handle bracket 204, and an outer spring 206 is fixedly installed on the rotating cutting plate 207. The other end of the outer spring 206 is fixedly installed on the handle bracket 204. The rotating cutting plate 207 is arc-shaped, and one end of the rotating cutting plate 207 is provided with a Cutting edge, a main cutting plate 210 is slidably installed on the support frame 107, a main spring 211 is fixedly installed on the main cutting plate 210, and the other end of the main spring 211 is fixedly installed on the support frame 107, the main cutting plate 210 is arc-shaped, and a cutting knife is provided at one end of the main cutting plate 210, the side cutting plate 208 and the rotating cutting plate 207 are symmetrically arranged, the main cutting plate 210 and multiple side cutting plates 208 and the rotating cutting plate 207 form a ring, the main cutting plate 210 and multiple side cutting plates 208 and the rotating cutting plate 207 are provided with overlapping margins to prepare for increased diameter, the main cutting plate 210 and multiple side cutting plates 208 and the rotating cutting plate 207 are in use together with the outer wall of the tree trunk 101 to remove branches on the outer wall of the tree trunk 101.

[0023] Working principle: The device is manually moved and then placed next to the tree trunk 101. When in use, the worker uses his knees or thighs to support the protective cover 105, and then holds the handle ring 205 with both hands at the same time. Then, the handle ring 205 is manually driven to rotate outward, so that the device can be close to the tree trunk 101. After the main tire 104 of the device contacts the outer wall of the tree trunk 101, the handle ring 205 can be released. In this way, the main tire 104 and the symmetrically arranged clamping sub-wheels 203 can clamp the tree trunk 101, thereby restricting the device to the outside of the tree trunk 101.

[0024] When the main tire 104 and the clamping pair wheel 203 are Figure 1In the state, the main cutting plate 210 and the multiple side cutting plates 208 and the rotating cutting plate 207 will fit the outer wall of the tree trunk 101. If the diameter of the tree trunk 101 is too large, the main cutting plate 210 and the multiple side cutting plates 208 and the rotating cutting plate 207 will be moved outward by compressing the outer spring 206, the side spring 209 and the main spring 211 to adapt to the diameter of the tree trunk 101. The working limit of this device is the overlap of the main cutting plate 210 and the multiple side cutting plates 208 and the rotating cutting plate 207. When the diameter of the tree trunk 101 is small, the outer spring 206, the side spring 209 and the main spring 211 will drive the main cutting plate 210, the multiple side cutting plates 208 and the rotating cutting plate 207 to move inward, so that the main cutting plate 210, the multiple side cutting plates 208 and the rotating cutting plate 207 are in contact with the outer wall of the tree trunk 101, and the limit of the main cutting plate 210, the multiple side cutting plates 208 and the rotating cutting plate 207 is the natural state of the outer spring 206, the side spring 209 and the main spring 211.

[0025] When the main tire 104 and the clamping pair wheel 203 are Figure 1 When cleaning after the state, it is necessary to align the cutting edges of the main cutting board 210, the multiple side cutting boards 208, and the rotating cutting board 207 with the branches on the outer wall of the tree trunk 101, and then start the engine 102, so that the engine 102 drives the main tire 104 to rotate through the belt 103, and then the main tire 104 moves the device away from the ground. During the movement, if a branch on the outer wall of the tree trunk 101 is encountered, the cutting edges on the main cutting board 210, the multiple side cutting boards 208, and the rotating cutting board 207 will cut off the branch, and the movement of the tree trunk 101 can be controlled by the remote control device to control the rotation of the engine 102, so that the engine 102 can be controlled to move up or down. The above description is only a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
