[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This invention utilizes a rotating shaft to drive the sleeve and rotating ring to rotate synchronously, enabling the rotary tiller blades to till the soil. When the rotary tiller blades encounter stones, they will encounter significant resistance and be unable to rotate. The rotating ring will then rotate relative to the sleeve, causing the first and second magnetic plates to demagnetize and gradually compress the telescopic rod. If the stone is small, the counterforce provided by the telescopic rod during compression will gradually increase, eventually causing the rotary tiller blades to turn the stone out of the soil. If the stone is large, even after the telescopic rod is fully compressed, the rotary tiller blades may still be unable to turn the stone out. In this case, the rotating ring will drive the sleeve to rotate synchronously relative to the rotating shaft, causing the sleeve to slide along the rotating ring and the rotary tiller blades on the rotating shaft. This allows the rotary tiller blades to avoid the stone and prevents them from becoming stuck on the stone, which could damage the machine. Attached Figure Description

After the stones are turned out, the elasticity of the telescopic rod 13 will push the first magnetic plate 8 and the second magnetic plate 10 back into the magnetically attractive state, so that the sleeve 9 drives the rotary ring 5 to rotate synchronously again. If the stones are large, the rotary tiller 7 cannot turn the stones out after the telescopic rod 13 is fully compressed, so the rotary ring 5 will drive the sleeve 9 to rotate synchronously with the rotating shaft 4. Through the cooperation of the threaded strips 14 and the threaded grooves 15, the corresponding sleeve 9 drives the rotary ring 5 and the rotary tiller 7 to slide on the rotating shaft 4, the corresponding torsional spring 16 also rotates to store energy and stretch and compress correspondingly, so that the rotary tiller 7 can avoid the stones and prevent the rotary tiller 7 from being stuck in the stones, causing damage to the machine. After the rotary tiller 7 passes through the stones, the elasticity of the torsional spring 16 will push the corresponding sleeve 9, rotary ring 5 and rotary tiller 7 back to their original positions. The elasticity of the telescopic rod 13 can also push the rotary ring 5 back to its original position, so that the sleeve 9 drives the rotary ring 5 and the rotary tiller 7 to return to normal soil turning. A protective sleeve 17 is arranged between the two adjacent rotary rings 5 to protect the torsional spring 16 and the rotating shaft 4. The two ends of each protective sleeve 17 are fixedly connected to the corresponding fixed plate 11, and each protective sleeve 17 is made of elastic material. During the sliding and rotating of the sleeve 9, the protective sleeve 17 can be stretched correspondingly to prevent the soil from being stuck in the torsional spring 16 or falling onto the rotating shaft 4 to hinder the sliding of the sleeve 9.

[0021] A fixed frame 19 is fixedly installed on the frame 1, and a plurality of connecting rods 20 are fixedly installed at the lower end of the fixed frame 19. Each connecting rod 20 is fixedly installed with a ploughshare 21 for soil turning at the lower end. The lower end of each connecting rod 20 is arranged in an arc shape, and each ploughshare 21 is arranged in a conical shape for easy soil turning. After the rotary tiller 7 rotates to turn the soil, the ploughshare 21 will pass through the turned soil again to turn the soil again, improving the soil turning effect of the soil turning machine and having a certain effect on soil arrangement. At the same time, when the ploughshare 21 encounters stones, since the end of the ploughshare 21 is wedge-shaped and the lower end of the connecting rod 20 is also arranged in an arc shape, the ploughshare 21 can shovel the stones in the soil and make the stones move upward along the lower end of the connecting rod 20, which is convenient for picking out the stones in the soil.

[0022] Specifically, in the initial state, the first magnetic plate 8 is in a magnetic attraction state with the corresponding second magnetic plate 10, and the telescopic rod 13 is also in an elongated state. After starting the engine 2, the transmission belt of the transmission mechanism 3 drives the rotation of the rotating shaft 4. During the rotation of the rotating shaft 4, the screw groove 15 limits the screw strip 14, and the elastic force of the torsional spring 16 prevents the sleeve 9 from sliding. The rotating shaft 4 drives the sleeve 9 to rotate synchronously, and the elastic force of the telescopic rod 13 and the magnetic attraction force between the first magnetic plate 8 and the second magnetic plate 10 make the sleeve 9 drive the rotating ring 5 to rotate synchronously, and the rotary tiller 7 performs a circular motion around the rotating shaft 4 to plow the soil. At the same time, the limiting groove 12 limits the limiting ring 6, which can make the rotating ring 5 stably installed between the two fixed plates 11, so that the rotating ring 5, the sleeve 9, and the central axis of the rotating shaft 4 always remain consistent. When the rotary tiller 7 does not encounter stones, the resistance of the soil to the rotary tiller 7 is small, and the first magnetic plate 8 and the second magnetic plate 10 do not release the magnetic attraction state. When the rotary tiller 7 encounters stones, it will be subjected to a larger resistance and cannot rotate, the rotating ring 5 will rotate relative to the sleeve 9, the first magnetic plate 8 and the second magnetic plate 10 will release the magnetic attraction state, and the telescopic rod 13 will be gradually compressed to buffer the rotary tiller 7 and prevent the rotary tiller 7 from continuously rubbing against the stones, reducing the wear of the rotary tiller 7. Since the elastic force of the torsional spring 16 is greater than the elastic force of the telescopic rod 13, the torsional spring 16 will not rotate and store energy during the gradual compression of the telescopic rod 13, and the sleeve 9 always rotates synchronously with the rotating shaft 4. The rotating ring 5 corresponding to the rotary tiller 7 that does not contact the stones still rotates synchronously with the rotating shaft 4. If the stones are small, the counterforce provided by the telescopic rod 13 during the continuous compression process will gradually increase, and finally the rotary tiller 7 will turn the stones out of the soil. After the stones are turned out, the elastic force of the telescopic rod 13 will push the first magnetic plate 8 and the second magnetic plate 10 back to the magnetic attraction state, making the sleeve 9 drive the rotating ring 5 to rotate synchronously again. If the stones are large, the telescopic rod 13 is fully compressed, and the rotary tiller 7 still cannot turn the stones out, the rotating ring 5 will drive the sleeve 9 to rotate synchronously relative to the rotating shaft 4. Through the cooperation of the screw strip 14 and the screw groove 15, the corresponding sleeve 9 drives the rotating ring 5 and the rotary tiller 7 to slide on the rotating shaft 4, the corresponding torsional spring 16 also rotates and stores energy, and performs corresponding stretching and compression, so that the rotary tiller 7 can avoid the stones and prevent the rotary tiller 7 from being continuously stuck in the stones, causing damage to the machine. After the rotary tiller 7 passes through the stones, the elastic force of the torsional spring 16 will push the corresponding sleeve 9 and the rotating ring 5 to drive the rotary tiller 7 to reset, and the elastic force of the telescopic rod 13 can also reset the rotating ring 5, so that the sleeve 9 drives the rotating ring 5 and the rotary tiller 7 to return to normal plowing. During the sliding and rotating of the sleeve 9, the protective sleeve 17 can be stretched correspondingly to prevent mud from getting stuck in the torsional spring 16 or falling onto the rotating shaft 4 to hinder the sliding of the sleeve 9. After the rotary tiller 7 rotates to plow the soil, the plowshare 21 will pass through the plowed land again to plow the soil again, improving the plowing effect of the plow.And can play a certain effect to the soil, at the same time when the ploughshare 21 encounter stone, because the ploughshare 21 end is wedge-shaped, and the lower end of connecting rod 20 is also set to arc, ploughshare 21 can shovel up the stone in the soil, and make the stone be limited by connecting rod 20 along the lower end of connecting rod 20 upward movement, facilitate the stone in the soil out.
