Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
Referring to fig. 1 to 11, the utility model comprises a rotary tillage box 1, a rotary tillage shaft 2, a rotary blade 3, a frame 4, a blade fixing frame 5 behind the rotary blade 3, and a grass cutting blade 6 fixed on the blade fixing frame 5.
The fixed blade frame 5 is composed of a fixed blade beam 7, a connecting sheet 8 and a stabilizing sheet 9, the connecting sheet 8 is fixed on two sides of the joint of the frame 4 and the rotary tillage box 1 by screws, one side of the fixed blade beam 7 is connected with the connecting sheet 8, the other side is connected with one side of the stabilizing sheet 9 by screws, and the other side of the stabilizing sheet 9 is fixed on the left side and the right side of the front of the frame 4 by screws.
The grass cutting knife 6 comprises a strip-shaped left blade knife 10, a strip-shaped right blade knife 11, a narrow-end left blade knife 12, a narrow-end right blade knife 13, a strip-shaped middle blade knife 14, an inner blade bent knife 15, a strip-shaped left blade right bent knife 16, a strip-shaped right blade left bent knife 17, a strip-shaped middle blade right bent knife 18 and a strip-shaped middle blade left bent knife 19.
The left strip-shaped blades 10, the left narrow-end blades 12, the right strip-shaped blades 14, the bent inner blades 15, the right strip-shaped blades 16, the right strip-shaped blades 18 are fixed on the blade fixing cross beam 7 on the left side of the frame 4 and have downward blades, the blade surfaces of the left strip-shaped blades are parallel to and close to but do not contact with the blade surfaces of the corresponding rotary blades 3, the right strip-shaped blades 11, the right narrow-end blades 13, the right strip-shaped blades 14, the bent inner blades 15, the left strip-shaped blades 17, the left strip-shaped blades 19 are fixed on the blade fixing cross beam 7 on the right side of the frame 4 and have downward blades, and the blade surfaces of the right strip-shaped blades 3 are parallel to and close to but do not contact with the blade surfaces of the corresponding rotary blades 3.
