The main shaft 1 can rotate to drive the spiral tilling blade 2 to till the soil, and turn the lower layer of soil to the upper layer. Shaft sleeves 3 are sleeved on both sides of the main shaft 1 and are rotatably connected thereto. Brackets 4 are fixedly provided on the periphery of the shaft sleeve 3 and are fixedly connected thereto. Connecting rods 5 are provided at the ends of the brackets 4 on both sides to fix the two together, and are used to fix the main shaft 1 and the device thereon. A traction frame 6 is fixedly provided on the upper side of the connecting rod 5, and is used to use a tractor to tow the tilling device.

[0021] A shaft sleeve 2 7 is fixedly provided on the bracket 4 and is fixedly connected to it, and a screw 8 is provided inside the shaft sleeve 2 7 and is rotatably connected to it. The screw 8 can rotate, and a threaded sleeve 11 is sleeved on the screw 8 and is threadedly connected to it. When the screw 8 rotates, the threaded sleeve 11 can move on the screw 8 due to the threaded connection with the screw 8. A connecting rod 12 is fixedly provided on the lower surface of the threaded sleeve 11, and positioning rods 9 are fixedly provided in the middle of the brackets 4 on both sides. A positioning groove 10 is opened through the positioning rod 9, and the connecting rod 12 can slide with the positioning groove 10. The positioning groove 10 is used to position the connecting rod 12. A scraper 13 is provided at the bottom of the connecting rod 12. The scraper 13 is designed to be in a torsion shape, which can cut the soil on the tillage device, and can also better fit the shape of the spiral tillage piece 2 to scrape off the soil stuck on the main shaft 1 and the spiral tillage piece 2 thereon.

[0022] A transmission box 14 is provided at the front of the connecting rod 5, and a transmission rod 15 is provided on the upper side and the right side of the transmission box 14 and is rotatably connected to the transmission box 14. The two ends of the transmission rod 15 are connected by right-angle gear transmission. A large pulley rod 16 is fixedly connected to the end of the transmission rod 15 on the right side. A support sleeve 17 is sleeved on the large pulley rod 16, and the support sleeve 17 is fixedly connected to the bracket 4. The support sleeve 17 is used to support the large pulley rod 16. A large pulley 18 is provided at the end of the large pulley rod 16. A transmission belt 19 is provided on the large pulley 18 to be transmission-connected to the main shaft 1. The large pulley 18 rotates and drives the main shaft 1 to rotate through the transmission belt 19. It is connected to the rotating device provided at the rear of the tractor, and finally drives the main shaft 1 and the spiral tillage blade 2 thereon to rotate through a series of transmissions such as the small pulley 20.

[0023] A servo motor 21 is fixedly provided on the side surface of the bracket 4 at one side, and the output end of the servo motor 21 is fixedly connected to one end of the screw rod 8 for driving the screw rod 8 to rotate.

A connecting seat 23 is fixedly provided on the upper part of the protective cover 22 to connect to a hydraulic lifting device on the tractor to control the lifting and lowering of the plowing device.

[0025] Working principle:

[0026] When the device is in use, the device is fixed to the rear of the tractor through the traction frame 6, and the end of the transmission rod 15 provided on the upper part of the transmission box 14 is connected to the rotating device provided at the rear of the tractor for rotation, thereby driving the transmission rod 15 provided on the side of the transmission box 14 to rotate, and further driving the large pulley 18 to drive the main shaft 1 to rotate through the transmission belt 19 provided thereon, thereby driving the spiral tilling blade 2 thereon to till the land. After the tilling work is completed, the device is lifted, and the servo motor 21 is turned on to rotate the screw rod 8, so that the threaded sleeve 11 provided thereon moves, driving the connecting rod 12 to slide in the positioning groove 10, and then driving the scraper 13 to translate to scrape the soil on the main shaft 1. In combination with the slow rotation of the main shaft 1 and the shape of the scraper 13, the inner and outer sides of the spiral tilling blade 2 and the surface of the main shaft 1 can be scraped, completing a more comprehensive scraping, so that the tilling work can be carried out more smoothly.
