detailed description

The present invention will be further described below in conjunction with accompanying drawing.

As shown in Fig. 1-Fig. 5, a combination soil preparation machine for removing stubble and crushing soil, including a frame 1, a gear box 6 is installed in the middle of the front and lower part of the frame 1, and a power output device 8 is connected in front of the gear box 6 , a stubble cutter shaft 11 with a stubble cutter 10 is installed under the gear box 6;

The front disc assembly 12 is set at the middle front lower part of the frame 1, and the lifting oil cylinder 5 is arranged at the middle position of the frame 1. One end of the lifting oil cylinder 5 is connected with the support frame arranged on the top of the frame 1, and the connecting rod body 4 Hinged on the bracket 1, one end of the connecting rod body 4 is connected to the ground wheel 13, and the other end of the connecting rod body 4 is connected to the telescopic end of the lifting cylinder 5;

The middle rear of the frame 1 is provided with a rear disc assembly 14 , and the rear bottom of the frame 1 is provided with a connecting device 3 , and a deep loosening shovel 15 with a loosening board 16 is installed below the connecting device 3 .

In order to improve the loosening effect of the subsoiler shovel, the lower part of the subsoiler shovel 15 is set as an arc, and the angle d of the tip of the subsoiler shovel 15 is set at 12°-16°.

In order to further improve the loosening effect, two arc-shaped loosening plates 16 are symmetrically welded on both sides of the subsoiling shovel 15, and the angle b at the bottom of the two loosening plates 16 is 85°-95°.
