[0002] The straw return machine is a protective tillage machine that cuts and crushes the straw stubble in the field and then spreads or buries it in the soil. It consists of cutting, stubble breaking, crushing, spreading, crushing degree and stubble breaking depth adjustment, power transmission and other mechanisms. During operation, the high-speed rotating cutter, hammer claw or swing knife cuts the straw, picks up the stubble, and inputs it into the machine casing. After repeated shearing, rubbing, tearing and crushing by the fixed and moving knives, it is evenly scattered in the field.

[0003] When the straw returner is in use, the internal cutter constantly comes into contact with the ground soil and dry and wet straw to cut them.

[0035] During actual operation, when this device is used, when the cutting disk 4 needs to be cleaned, the staff first rotates the bolt 2203, and the bolt 2203 rotates inside the clamping rod 2201 and moves outward to disengage from the connection relationship between the bolt 2203 and the second set frame 2103. Then the staff holds the handle 1203 and flips it downward. The handle 1203 flips downward and drives the fixed plate 1104 to flip upward through the rocker 1201 and the rotating drum 1103. The fixed plate 1104 flips upward and drives the cleaning block 1105 to flip upward, so that the cleaning block 1105 flips upward to the left and right sides of the cutting disk 4 to complete the contact with the left and right sides of the cutting disk 4. Then the staff starts the equipment again to drive the cutting disk 4 to rotate, so that the cleaning block 1105 contacts with the left and right sides of the cutting disk 4 to complete the cleaning of the left and right sides of the cutting disk 4. At this time, the cleaning work of the cutting disk 4 is completed.
