Detailed ways

The utility model will be further described below in conjunction with the examples, but not as a limitation to the utility model.

Please refer to Fig. 1 and Fig. 2, the green belt pruning machine involved in the present embodiment includes a trolley 1, a top pruning mechanism and a side pruning mechanism. Dolly 1 is a four-wheel cart, which is convenient for the advancement of green belt pruning operations. The trolley 1 is fixedly connected with a bracket 2. The bracket 2 can be used as a suspension frame for the four wheels of the trolley 1, and also as a main operating handrail for the staff. There is no fixed requirement for the specific form of the bracket 2. In the drawings of this embodiment, only the The most basic is a tubular member. The bracket 2 is provided with a longitudinal guide rail 3, the longitudinal guide rail 3 is fixed with a forearm cover 4, and the forearm cover 4 is provided with a front transverse arm 5. The rear arm cover 6 that can slide along the longitudinal guide rail 3 is also provided on the longitudinal guide rail 3 . The rear arm cover 6 is fixedly provided with a vertical arm 7, the vertical arm 7 is provided with a slidable lower arm cover 8, and the lower arm cover 8 is provided with a rear transverse arm 9. Both the front transverse arm 5 and the rear transverse arm 9 are hydraulic telescopic rods, that is, the front transverse arm 5 and the rear transverse arm 9 can adjust their own lengths. The head end of the front transverse arm 5 is provided with a vertical shaft 10, and the vertical shaft 10 is sleeved with an eccentric shaft 11 parallel to the vertical shaft 10, and the eccentric shaft 11 can perform circular motion with the vertical shaft 10 as a rotating shaft. A torsion spring 12 is provided between the vertical shaft 10 and the eccentric shaft 11. When the eccentric shaft 11 is subjected to external force and performs circular motion with the vertical shaft 10 as the rotating shaft, the torsion spring 12 is compressed. When the external force is removed, the eccentric shaft 11 is reset. to the original position. The bottom of the eccentric shaft 11 is fixedly connected with the top trimming mechanism, and the head end of the rear transverse arm 9 is fixedly connected with the side trimming mechanism. Top trimming mechanism comprises the cuboid cover 13 of bottom surface opening, and front trimming motor 14 and front trimming knife 15 are provided with in the cuboid cover 13, and front trimming motor 14 is used to drive front trimming knife 15 to rotate, and the trimming face of front trimming knife 15 is arranged downwards . The connecting point of the eccentric shaft 11 and the top surface trimming mechanism deviates from the center of gravity of the top surface of the cuboid cover 13. In the present embodiment, the front trimming motor 14 is provided with two side by side, and the eccentric shaft 11 is positioned at one of the front trimming motors 14. above. The side pruning mechanism comprises an 8-shaped side plate 16, and a baffle plate 17 is arranged on the rear side of the 8-shaped side plate 16, and the baffle plate 17 mainly blocks residual branches under pruning from flying to the operator.
