After the adjustment, the first gear 1801 is driven to rotate through the operation of the motor 1805, and the second gear 1802 is synchronously driven to rotate through the toothed belt 1803, thereby driving the connecting column 1804 fixed at both ends of the second gear 1802 to rotate, driving the two blocks 6 connected by the two connecting columns 1804 to rotate, thereby driving the two rotary tillage rollers 7 clamped by the two blocks 6 to rotate, and performing rotary tillage processing, so that the vehicle body 1 is moved, and the top plate 2004 is driven to move downward through the thrust of the spring 2005, thereby driving the two sliding columns 2002 to descend, so that the smoothing plate 2004 fixed at the bottom ends of the two sliding columns 2002 is fixed together. 03 is lowered to make it close to the ground. When the front end of the vehicle body is rotary tilled, the smoothing plate 2003 at its rear end will automatically press and smooth the rotary tilled soil. By unscrewing the bolt 16, the two movable plates 9 can be directly slid in opposite directions, so that the clamping column 10 fixed at one end of the two movable plates 9 is disengaged from the second clamping groove 11 opened at the opposite end of the two rotary tilling rollers 7. At this time, the user can directly slide out the two rotary tilling rollers 7 and replace them separately. During installation, the two rotary tilling rollers 7 are guided to be installed through the setting of the clamping block 6 and the first clamping groove 8. After installation, the two movable plates 9 are moved toward each other, so that the two clamping columns 10 are clamped in the second clamping groove 11 opened in the rotary tilling roller 7, and both ends of the rotary tilling roller 7 are limited. Finally, the bolt 16 is screwed on to fix the position of the two movable plates 9 to achieve the installation effect.
