[0023] The present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0024] A rotary tiller Figure 1 As shown, it includes a shell 1 and a power shaft 2 rotating in the shell 1. The power shaft 2 is rotated by being connected to a motor. A rotating shaft 3 is rotatably connected in the shell 1 in the opposite direction of rotation to the power shaft 2. A plurality of blades 1 4 are detachably provided on the power shaft 2, and a plurality of blades 2 5 are detachably provided on the rotating shaft 3. The blades 2 5 are located between adjacent blades 1 4. The rotating shaft 3 can be close to or away from the power shaft 2. By setting the rotating shaft 3 in the opposite direction of rotation to the power shaft 2, a blade 1 4 is provided on the power shaft 2, and a blade 2 5 is provided on the rotating shaft 3, so that the blade 1 4 and the blade 2 5 rotate in opposite directions, and the blade 2 5 is located between adjacent blades 1 4. Therefore, during the soil turning process, the blade 1 4 and the blade 2 5 can shear the rhizomes, reducing the possibility of the rhizomes being entangled with the power shaft 2 and the rotating shaft 3. After the rotating shaft 3 is away from the power shaft 2, the blade 2 5 can perform a second soil turning, thereby improving the soil turning effect.

[0025] like Figure 2 and Figure 5 As shown, blade 2 5 is Y-shaped, and the width of blade 2 5 is smaller than the distance between adjacent blades 1 4. By setting blade 2 5 into a Y shape, the shearing effect between blade 1 4 and blade 2 5 is improved. The width of blade 2 5 is smaller than the distance between adjacent blades 1 4, so that blade 2 5 can move away from blade 1 4 for secondary turning of the soil. Rotating columns 6 are integrally formed at both ends of the power shaft 2, and rotating columns 7 are integrally formed at both ends of the rotating shaft 3. Two sliding grooves 8 are provided on the shell 1 for accommodating the rotating columns 6 and the rotating columns 7 respectively. By fixing the two ends of the power shaft 2 with the rotating columns 6, rotating columns 7 are provided at both ends of the rotating shaft 3, and several sliding grooves 8 are provided on the shell 1 for accommodating the rotating columns 6 and the rotating columns 7. When the rotating columns 6 and the rotating columns 7 rotate in the corresponding sliding grooves respectively, the rotation of the power shaft 2 and the rotating shaft 3 is realized. When the rotating columns 6 and the rotating columns 7 slide in the corresponding sliding grooves respectively, the rotating shaft 3 is realized to move away from or approach the power shaft 2.

[0026] like Figure 3 and Figure 4 As shown, the rotating column 6 is connected to a gear 1 9 by a key, the rotating column 7 is connected to a gear 2 10 by a key, and a gear 3 11 and a gear 4 12 that mesh with each other are provided between the gear 1 9 and the gear 2 10, the gear 1 9 meshes with the gear 3 11, and the gear 2 10 meshes with the gear 4 12. By setting the rotating column 6 with a gear 1 9 fixedly connected, the rotating column 7 is fixedly connected, the gear 1 9 and the gear 2 10 are provided with a gear 3 11 and a gear 4 12 that mesh with each other, the gear 1 9 meshes with the gear 3 11, and the gear 2 10 meshes with the gear 4 12, the power shaft 2 rotates while driving the rotating shaft 3 to rotate, and the rotation direction of the rotating shaft 3 is opposite to that of the power shaft 2, a connecting rod 13 is provided between the gear 1 9 and the gear 3 11, and the two ends of the connecting rod 13 are respectively connected to the gear 1 9 and the gear 3 11 for rotation, a connecting rod 2 14 is provided between the gear 2 10 and the gear 4 12, and the two ends of the connecting rod 2 14 The two ends of the rotating rod 15 are respectively connected to the gear 2 10 and the gear 4 12, and the two ends of the rotating rod 15 are respectively connected to the connecting rod 13 and the connecting rod 2 14. By arranging the connecting rod 13 between the gear 1 9 and the gear 3 11, the connecting rod 2 14 is provided between the gear 2 10 and the gear 4 12, and the rotating rod 15 is provided between the gear 3 11 and the gear 4 12, the positions of the gear 3 11 and the gear 4 12 can be fixed. At the same time, the two ends of the connecting rod 13 are respectively connected to the gear 1 9 and the gear 3 11, and the two ends of the connecting rod 2 14 are respectively connected to the gear 2 10 and the gear 4 12. The two ends of the rotating rod 15 are respectively connected to the connecting rod 13 and the connecting rod 2 14. When the rotating rod 15 rotates, the connecting rod 13 and the connecting rod 2 14 are driven to rotate. At the same time, the connecting rod 13 and the connecting rod 2 14 are displaced, thereby realizing that the rotating shaft 3 is close to or away from the power shaft 2.

[0027] like Figure 1 and Figure 6 As shown, protective covers 16 are provided on both sides of the shell 1, and the protective covers 16 cover gear 1 9, gear 2 10, gear 3 11, gear 4 12, connecting rod 13, connecting rod 2 14 and rotating rod 15. By providing the protective cover 16, the protective cover 16 covers gear 1 9, gear 2 10, gear 3 11, gear 4 12, connecting rod 13, connecting rod 2 14 and rotating rod 15, and the protective cover 16 has a sealing effect, which increases the durability of the rotary tiller. A rotating shaft 17 is fixedly connected to the rotating rod 15, and a through hole is opened on the protective cover 16 for the rotating shaft 17 to pass through. A rotating disk 18 is provided at one end of the rotating shaft 17 extending out of the shell 1. By fixing the rotating shaft 17 on the rotating rod 15, a through hole is opened on the protective cover 16 for the rotating shaft 17 to pass through. A rotating disk 18 is provided at one end of the rotating shaft 17 extending out of the shell 1. By rotating the rotating disk 18, the rotating rod 15 is facilitated to rotate.

[0028] like Figure 6As shown, the cross-section of the portion of the rotating shaft 17 extending from the protective cover 16 is square, and the rotating disk 18 is slidably connected to the portion of the rotating shaft 17 extending from the protective cover 16. A fixing column 19 is integrally formed on the protective cover 16, and eight fixing holes 20 are opened on the rotating disk 18 through which the fixing columns 19 pass. By setting the cross-section of the portion of the rotating shaft 17 extending from the protective cover 16 to be square, the rotating disk 18 is slidably connected to the portion of the rotating shaft 17 extending from the protective cover 16, so that the rotating disk 18 can drive the rotating shaft 17 to rotate while sliding, and after the rotating disk 18 slides, the fixing holes 20 on the rotating disk 18 are passed through by the fixing columns 19 on the protective cover 16, thereby limiting the rotation of the rotating disk 18.

[0029] Working process: When it is necessary to cut the roots in the soil, the operator pulls the rotating disk 18 away from the rotating shaft 17. During this process, the rotating disk 18 slides on the part of the rotating shaft 17 extending out of the protective cover 16, and the fixing column 19 is separated from the fixing hole 20, so that the rotating disk 18 can rotate. Then the operator rotates the rotating disk 18. At this time, the rotating shaft 17 rotates under the drive of the rotating disk 18. The rotating shaft 17 rotates in the through hole. At the same time, the rotating rod 15 also rotates under the drive of the rotating shaft 17. Since the two ends of the rotating rod 15 are respectively connected to the connecting rod 1 13 and the connecting rod 2 14, the connecting rod 1 13 and the connecting rod 2 14 are driven to rotate. At the same time, the centers of the connecting rod 13 and the connecting rod 2 14 gradually approach the rotating rod 15. Since the two ends of the connecting rod 13 are respectively connected to the gear 1 9 and the gear 3 1 1 is rotationally connected, and the two ends of the connecting rod 2 14 are rotationally connected with the gear 2 10 and the gear 4 12 respectively, so that the power shaft 2 and the rotating shaft 3 are close to each other. When the blade 2 5 is displaced between the adjacent blades 1 4, the operator applies a force to the rotating disk 18, so that the rotating disk 18 slides toward the rotating shaft 17. At the same time, the fixing column 19 passes through the fixing hole 20 on the rotating disk 18 to complete the fixation of the rotating disk 18. Then the operator starts the motor, and the motor drives the power shaft 2 to rotate. The gears 1 9 at both ends of the power shaft 2 drive the gear 3 11 to rotate, the gear 3 11 drives the gear 4 12 to rotate, and the gear 4 12 drives the gear 2 10 to rotate, so that the rotating shaft 3 rotates. At this time, the rotation direction of the rotating shaft 3 is opposite to that of the power shaft 2. The blade 1 4 and the blade 2 5 can shear the roots while turning the soil.

[0030] When improving the soil turning effect, the operator also pulls out the rotary disk 18, and the rotary disk 18 can rotate at this time. Then the operator rotates the rotary disk 18 in the opposite direction. At this time, the rotating shaft 3 and the power shaft 2 move away from each other. Then the operator slides the rotary disk 18 again to fix the rotary disk 18, so that when turning the soil, after the blade 1 4 turns the soil, the blade 2 5 can turn the soil for the second time.

All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, certain improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
