Forestry engineering includes forest area planning, forest cultivation, forest protection, forest exploitation, wood product design and processing, design and manufacture of exploitation equipment, design and manufacture of wood product processing equipment, forest area fire prevention technology and equipment, etc. During the growth process of trees, it is necessary to prune redundant branches;

[0003] When the existing tree pruning device prunes the upper branches of a tree, generally, the pruner controls the pruning machine to prune. For some trees with thicker main branches, the pruner needs to repeatedly surround the main branch for pruning, resulting in very cumbersome operations during pruning. Moreover, since the tree pruning machine has a certain weight, when moving in the forest, it needs to be manually held. It is laborious and there are also great safety hazards due to the exposure of the blades on the pruning machine. In view of the above defects, the present utility model is proposed.

[0023] The following further elaborates the present utility model in combination with the accompanying drawings and embodiments on the above and other technical features and advantages of the present utility model. However, the following embodiments are only the preferred embodiments of the present utility model and not all of them. Embodiment

[0024] As Figures 1-4 shown, the present utility model provides a tree pruning device that is easy to use, including a pruning body 1 and pruning blades 2. Pruning blades 2 are fixed on the top surfaces of both pruning bodies 1. Driving crawlers 3 are arranged inside the pruning bodies 1 below the two pruning blades 2. Support plates 4 are fixed at both ends of the pruning body 1, and servo cylinders 5 are arranged on the pruning body 1 outside the support plates 4. One end of the support plate 4 far from the pruning body 1 is rotatably connected to a rotating connecting plate 6, and one end of the rotating connecting plate 6 far from the support plate 4 is rotatably connected to a moving roller 7. The output ends of the servo cylinders 5 are rotatably connected to the rotating connecting plates 6 and are used to push the rotating connecting plates 6 and the moving rollers 7 to hold the tree tightly;

[0025] On opposite sides of the two pruning bodies 1, a first connecting plate 9 and a second connecting plate 10 are respectively rotatably connected, and the first connecting plate 9 and the second connecting plate 10 are connected by an adjusting assembly. In the middle of the outer side of the second connecting plate 10, a fixing plate 11 is fixed, and a pulling rope 15 is arranged on the fixing plate 11 for pulling the pruning body 1. On the side of the pruning body 1 away from the driving track 3, handles 8 are fixed. The first connecting plate 9 and the second connecting plate 10 are arranged as mutually matching arcs. On the opposite sides of the first connecting plate 9 and the second connecting plate 10, chutes for mutual cooperation are provided. The innermost surfaces of the first connecting plate 9 and the second connecting plate 10 are flush. By adjusting the distance between the two pruning bodies 1 through the first connecting plate 9 and the second connecting plate 10, it is more convenient to adapt to trees with different diameters.

[0026] Both of the two pruning blades 2 are arranged as arcs, which is convenient for the pruning blades 2 to prune the trees. The two support plates 4 are respectively located at the upper and lower parts on the outer sides of the two pruning bodies 1, and the distance between the two support plates 4 is greater than the height of the moving rollers 7. The two moving rollers 7 are both located on the outer sides of the pruning blades 2 and the driving track 3. It is convenient for the two moving rollers 7 to have flush outer sides under the push of the servo cylinder 5. Thus, after the pruning body 1 is placed horizontally, it can be supported by the moving rollers 7 for subsequent movement of the pruning body 1.

[0027] The adjusting assembly includes a moving screw 18, an adjusting groove 19 and a second nut 21. On the side of the first connecting plate 9 close to the second connecting plate 10, the moving screws 18 are symmetrically fixed. The moving screws 18 are slidably inserted into the adjusting grooves 19 opened in the second connecting plate 10. At one end of each moving screw 18 extending to the outside of the second connecting plate 10, a second nut 21 is threadedly sleeved. When the second nut 21 is screwed to release the clamping and fixing with the second connecting plate 10, after the release, the first connecting plate 9 can be pulled to drive the moving screw 18 to slide in the adjusting groove 19, and then the distance between the two pruning bodies 1 can be adjusted. After the adjustment is completed, the second nut 21 can be screwed to clamp and fix the second connecting plate 10 again.

[0028] On the moving screw 18 between each second nut 21 and the second connecting plate 10, a cushion plate 20 is slidably sleeved, and the side of the cushion plate 20 away from the second nut 21 is arranged as an arc matching the fixing plate 11. When the second connecting plate 10 is fixed by the second nut 21, by pushing the cushion plate 20 to abut against the outer surface of the second connecting plate 10, the contact area during clamping can be increased. Each moving screw 18 is arranged as a horizontally placed "T" shape.

[0029] In the middle of the outer side of the fixing plate 11, a fixing screw rod 12 is fixed, and a winding roller 13 is rotatably sleeved on the fixing screw rod 12. When pulling the trimming machine body 1, pull the first nut 14 to drive the winding roller 13 to rotate for wire release. The end of the pulling rope 15 is fixed on the outer surface of the winding roller 13. A first nut 14 is threadedly sleeved on the fixing screw rod 12 on the side of the winding roller 13. After the wire release is completed, turn the first nut 14 to clamp and fix the winding roller 13, so that wire release cannot be carried out by rotating the winding roller 13. Pull the pulling rope 15, and the trimming machine body 1 can be driven to move through the winding roller 13 and the fixing screw rod 12. The wire release length of the pulling rope 15 can be adjusted according to the height of the trimming personnel.

[0030] The fixing screw rod 12 is arranged in a horizontal "T" shape, which is convenient for winding and storing the pulling rope 15. The length of the threaded section of the fixing screw rod 12 is greater than the sum of the lengths of the first nut 14 and the winding roller 13. The inner diameter of the winding roller 13 is greater than the diameter of the threaded section of the fixing screw rod 12 to ensure that the winding roller 13 can rotate normally.

[0031] One end of the pulling rope 15 away from the winding roller 13 is fixed with a pull ring 16, which is convenient for pulling the pulling rope 15. A hanging rod 17 is fixed on the outer surface of the fixing plate 11 on the side of the fixing screw rod 12 for hanging the pull ring 16. That is, when winding the pulling rope 15, wind the pulling rope 15 around the winding roller 13, hang the pull ring 16 on the hanging rod 17, rotate the winding roller 13 so that the pull ring 16 abuts against the hanging rod 17, and then turn the first nut 14 to clamp and fix the winding roller 13, and the pulling rope 15 can be wound around the winding roller 13. The winding roller 13 is arranged in a horizontal hollow "T" shape.

[0032] The above is only the preferred embodiment of the present invention, which is illustrative rather than restrictive to the present invention. Those skilled in the art understand that many changes, modifications, and even equivalents can be made within the spirit and scope defined by the claims of the present invention, but all will fall within the protection scope of the present invention.
