Abstract

The utility model provides a corn straw smashing and returning integrated device, which relates to the technical field of straw smashing and comprises a device body. The device body is provided with a bearing protection shell in the front-back direction, bearing holes penetrating front and back are formed in the bottoms of the left ends of the front wall and the rear wall of the bearing protection shell correspondingly, and semicircular head blocks with threaded holes penetrating up and down are arranged in the middles of the right ends of the front end face and the rear end face of the bearing protection shell correspondingly. A bearing lifting rod in the vertical direction is installed in a cup head block of a bearing protection shell through threads, the bearing lifting rod is conveniently installed on the bearing protection shell through threads to bear a roller bearing block, and the roller bearing block conveniently carries a lifting moving wheel to descend to make contact with the ground to achieve pushing movement. The problems that the device is difficult to move after being separated from mobile mechanical equipment due to the fact that the device is moved through the external mobile mechanical equipment, and moving measures are inconvenient to add on the device so that the device can be pushed to move are solved.
