It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0044] like Figures 1 to 7 As shown, a corn combined operation machine with straw and soil crushing comprises: an operation machine body; a film covering device 9, which is arranged at the rear of the operation machine body; a grass cutting device 8, which is arranged in the film covering device 9, and is used to crush the straw and soil in the soil picked up by the film covering device 9; the film covering device 9 comprises: a soil retaining box; an upper soil chain plate 5, the bottom of which corresponds to the land, and the top is arranged in the soil retaining box, and the upper soil chain plate drive shaft 10 is connected to the power transmission part of the operation machine body; a plurality of soil chutes 7, which are arranged on the rear outlet of the soil retaining box, and the outlet ends thereof correspond to the two sides of the ground film; wherein the soil retaining box comprises: an upper connecting plate 92, the rear end of the upper connecting plate 92 is an arc plate, the arc radius of the arc plate is 70 mm, and the angle between the rear edge of the arc plate and the upper connecting plate 92 is 80 degrees; two side plates 93, which are respectively arranged on both sides of the upper connecting plate 92; and a front baffle plate 91, which is arranged in front of the upper connecting plate 92.

[0045] like Figure 7 As shown, the grass cutting device 8 includes: a knife shaft 81, which is horizontally arranged in the soil retaining box, and its power input end is connected to the power transmission part of the working machine body; a plurality of blade fixing plates 82, which are evenly distributed on the knife shaft 81; and a plurality of blades 83, which are fixedly installed on the blade fixing plate 82.

[0046] like Figures 1 to 4 As shown, the working machine body includes: a frame 16; a gearbox 2, which is arranged at the front end of the frame 16, and its power input end is connected to the power source; a rotary tillage part 3, which is arranged at the lower side of the front end of the frame 16; a fertilizer box 11, which is arranged on the frame 16, and its bottom discharge port is connected to the feed end of the fertilizer plow 4 arranged at the bottom of the frame 16; a film laying device 6, which is arranged at the lower side of the rear end of the frame 16; wherein, the power input parts of the rotary tillage part 3 and the fertilizer box 11 are connected to the power transmission part of the working machine body.

[0047] like Figures 1 to 4 As shown, the utility model further comprises a traction part 1, which is arranged at the front end of the frame 16 and is used for connecting with the traction equipment.

[0048] like Figures 1 to 4 As shown, the power transmission part includes: a first sprocket transmission assembly 12, one end of which is connected to the first output shaft of the gearbox 2, and the other end is connected to the power input shaft of the rotary tillage part 3; a fourth sprocket transmission assembly 15, one end of which is connected to the second output shaft of the gearbox 2, and the other end is connected to one end of the upper soil chain plate drive shaft 10; a second sprocket transmission assembly 13, one end of which is connected to the input shaft of the fertilizer box 11, and the other end is connected to the other end of the upper soil chain plate drive shaft 10, and the upper soil chain plate drive shaft 10 is connected to the knife shaft 81 through the third sprocket transmission assembly 14.

[0049] When the utility model is in use, the traction equipment pulls the utility model to the working area through the traction part 1.
