[0025] The protective mechanism also includes an L-shaped protective plate 13 arranged on the left side of the housing 1. The upper end of the housing 1 is fixedly connected to a U-shaped connecting frame 9. The U-shaped connecting frame 9 is equipped with a lifting mechanism for moving the L-shaped protective plate 13 up and down. The lifting mechanism includes a lifting bar 12 arranged between two vertical parts of the U-shaped connecting frame 9. The rear side of the L-shaped protective plate 13 is fixedly connected to the front side of the lifting bar 12. The lifting bar 12 is rotatably connected to a threaded rod 11. The upper end of the threaded rod 11 passes through the horizontal part of the U-shaped connecting frame 9 and is threadedly connected.

[0026] The upper end of the lifting bar 12 is symmetrically fixedly connected to two guide rods 10, and the upper ends of the two guide rods 10 both penetrate the horizontal part of the U-shaped connecting frame 9 and are slidably connected;

[0027] Among them, it also includes a disassembly mechanism, which is used to disassemble the blade body 6. The disassembly mechanism includes two connecting columns 7 fixedly connected to the front and rear inner walls of the collecting tank 4, each connecting column 7 is provided with a rectangular cavity, each rectangular cavity is provided with a sliding block 16 that can slide up and down, the upper end of each sliding block 16 is elastically connected to the inner top of the rectangular cavity through a spring 15, the upper end of each sliding block 16 is fixedly connected to a pull rod 14, the upper end of each pull rod 14 passes through the corresponding rectangular cavity top, and is fixedly connected to a pulling block 8, two rectangular grooves 18 are symmetrically arranged in the collecting tank 4, the lower ends of the two sliding blocks 16 are fixedly connected to a rectangular rod 17, two rectangular openings are symmetrically penetrated on the blade body 6, the lower end of each rectangular rod 17 passes through the corresponding rectangular cavity bottom and the rectangular opening in turn, and extends into the rectangular groove 18, the lower end face of the blade body 6 contacts the inner bottom of the collecting tank 4, and the upper end face of the blade body 6 contacts the upper end face of the connecting column 7, and in this way, the blade body 6 can be limited in the vertical direction.
