[0028] Two sealing strips 43 are fixedly provided at one end of each boss 22 facing the drum core 37, a channel 50 is opened inside the boss between the two sealing strips 43 on the side away from the drum core 37, a connecting rod 45 is slidingly sealed inside the channel 50, a piston 44 is fixedly provided at one end of the connecting rod 45 close to the sealing strip 43, a long cutting knife 23 is rotatably provided at the end of the connecting rod 45 away from the sealing strip 43, an arc-shaped tail 48 is provided at the connecting portion of the long cutting knife 23 and the connecting rod 45, a circular boss 49 is provided inside the channel 50 close to the arc-shaped tail 48, and the outer surface of the boss 49 fits the concave surface of the arc-shaped tail 48.

[0029] The projection 22 on each cutting drum corresponds to the recess 24 on the other cutting drum.

[0030] A first baffle 19 is provided on the lower side of the end of the fuselage 10 away from the storage bin 12, and a plurality of support legs 20 are fixedly provided at the bottom of the fuselage 10. A roller 21 is rotatably provided on the end of each support leg 20 away from the fuselage.

[0031] A second baffle 18 is fixedly disposed at a position near the opening 13 on the top of the body 10 , and a hand push assembly 17 is disposed on a side of the second baffle 18 away from the feed shell 11 .

[0032] An operating box 15 for controlling the rotation and elevation of the feed shell 11 is fixedly arranged on the top of the body 10 near the hand-pushing assembly 17 , and an operating rod 16 is arranged inside the operating box 15 .

[0033] Two conveying rollers 34 are rotatably arranged inside the fuselage 10 between the feed shell 11 and the crushing assembly 14. One end of each conveying roller 34 extends out of the fuselage 10. A conveyor belt motor 51 is fixedly arranged on the end of the conveying roller 34 extending out of the fuselage 10. The output end of the conveyor belt motor 51 is fixedly connected to the conveying roller 34. A conveyor belt 35 for delivering the broken branches to the crushing assembly 14 is provided on the surface of the conveying roller 34.

[0034] Working principle: When branches need to be crushed, the body 10 is directly pushed by the pushing assembly 17, and is directly moved to the position of branches that need to be crushed through the roller 21, so that the entrance of the feed shell 11 faces the branches.

[0035] After the position is adjusted, the drive motor 30 and the conveyor belt motor 51 are started. The output end of the drive motor 30 drives the driving gear 28 to rotate, and the driving gear 28 drives the two driven gears 26 to mesh and drive, thereby driving the two cutting rollers to rotate inward. The fuselage 10 is pushed to the position where there are branches. Under the guidance of the first baffle 19, the branches will enter the feed bin 11 and be cut by the two rotating cutting rollers. The cut branches fall onto the transmission belt 35 behind the feed bin 11. Driven by the conveyor belt, the cut branches will be sent to the crushing assembly 14 at the rear for crushing, and the crushed branch residues will be collected in the storage bin 12. The small branches remaining on the ground can be collected and poured directly into the opening 13 for direct crushing. When the storage bin 12 is full, the storage bin 12 can be disassembled from the fuselage 10, and the branch residues can be processed and then reinstalled back into the fuselage.

[0036] When the cutting drum cuts the branch, the long cutting knife 23 in the convex platform 22 on the surface of the cutting drum will press the branch into the concave platform 24 and push against the short cutting knife 25 inside the concave platform 24. Under the action of pressure, the branch will be bent, and the bent branch will be more easily cut by the long cutting knife 23 and the short cutting knife 25. When a branch with strong toughness is encountered and cannot be cut by the long cutting knife 23 and the short cutting knife 25, the long cutting knife 23 will be pressed back to the inside of the cutting drum for a distance. When the long cutting knife 23 is pushed back to the inside of the cutting drum, the arc-shaped tail 48 at the end of the long cutting knife 23 will push against the table surface in the channel 50. Under the action of the arc-shaped tail 48, the long cutting knife 23 will be folded inwards, and part of the bark fiber on the surface of the branch will be scraped off during the folding process. The toughness of the branch with the bark fiber scraped off will be relatively reduced, and the rear crushing component 14 can also crush the branch better.

[0037] When encountering some branches that have been broken off from high places but are still hanging on the tree, the fuselage 10 can be pushed under the branches that need to be broken, and the operating box 15 can be controlled by the operating lever 16 to control the rotating shaft 31 to rotate the feed shell 11 to the entrance facing the branches above. Continue to operate the operating lever 16 to control the telescopic rod 32 to extend until it can reach the branches at high places and then start to process the branches. The cut branches will directly fall onto the conveyor belt 35 under the feed shell 11. Since the cutting drum adopts the method of cutting branches, it can reduce the damage to the trees when breaking the branches at high places. After the upper branches are cleared, operate the operating lever 16 to return the feed shell 11 to its original position.

Any equivalent structure or equivalent process transformation made using the contents of the present invention's specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
