Part number description in the drawings:
1. the machine frame comprises a frame body, a deep rotary soil crushing shaft assembly, a 3-deep buried straw shaft assembly, a 4-transmission mechanism, a 5-power transmission box, a 6-deep rotary soil crushing shaft and a 7-deep buried straw shaft assembly the rotary tillage soil-crushing cutter comprises an arc-shaped cutter handle, an 8, a cutter holder, a 9, a rotary tillage soil-crushing cutter, a 10, a deeply buried straw shaft, an 11, spring teeth, a 12, a buried operation section, a 13 and a fixed section.
Detailed Description
The following describes the inventive embodiments in detail with reference to the drawings. The deep rotary soil crushing and deep straw burying soil preparation machine comprises a frame 1 and a power transmission box 5 assembled at the upper part of the frame 1, wherein a deep rotary soil crushing shaft assembly 2 and a deep straw burying shaft assembly 3 are rotatably assembled on the lower side part of the frame 1 from front to back in sequence, the deep rotary soil crushing shaft assembly 2 is connected with the deep straw burying shaft assembly 3 by a transmission mechanism 4, and the deep rotary soil crushing shaft assembly 2 is connected with the power transmission box 5; the deep rotary soil crushing shaft assembly 2 consists of a deep rotary soil crushing shaft 6, a cutter holder 8, arc cutter handles 7 and rotary tillage soil crushing cutters 9, wherein the cutter holder 8 is fixedly arranged on the deep rotary soil crushing shaft 6, an even number of arc cutter handles 7 are symmetrically and fixedly arranged on the same plane position outside the circumference direction of the cutter holder 8, the rotary tillage soil crushing cutters 9 are fixedly arranged on the outer end parts of the arc cutter handles 7, and the axial inclination directions of the rotary tillage soil crushing cutters 9 on the adjacent arc cutter handles 7 are opposite; the structure of the deeply buried straw shaft assembly 3 is as follows: n elastic teeth 11 are uniformly distributed on the deeply buried straw shaft 10 in a double-head spiral linear arrangement along the axial direction, the elastic teeth 11 are formed by connecting a fixed mounting section 13 with a buried operation section 12, the whole fixed mounting section 13 is in an arc surface shape, the radius size of the inner surface of the arc surface is matched with the radius size of the outer surface of the deeply buried straw shaft 10, the whole buried operation section 12 is in an involute surface shape, and the cross section of the buried operation section 12 is rectangular.
