[0030] As Figures 5-7 shown, the rotary tillage working part 4 includes a motor 401 fixed on the motor mounting plate 411 by bolts, the output end of the motor 401 is provided with a belt pulley, the spiral rotary tillage blade shaft 406 is clamped on the fixed plate 409 through two angular contact bearings 403, the two angular contact bearings 403 are locked by bolts, the bottom end of the spiral rotary tillage blade shaft 406 is provided with a U-shaped clamping groove, the top end of the spiral rotary tillage blade shaft 406 is provided with a sprocket 404, the sprocket 404 is locked with the spiral rotary tillage blade shaft 406 through a top pin, the blade shaft of the spiral rotary tillage blade 407 is welded with a cross-shaped buckle, the buckle on the spiral rotary tillage blade 407 is embedded in the U-shaped clamping groove at the bottom end of the spiral rotary tillage blade shaft 406, the top end of the spiral rotary tillage blade 407 is provided with a thread, which is fixed by a round nut 408, the number of the spiral rotary tillage blade shaft 406 and the spiral rotary tillage blade 407 is 9 groups, the top end of the 9 groups of spiral rotary tillage blade shaft 406 is provided with a sprocket 404, which is connected with each other through a chain 405, the chain 405 is tensioned by a tension pulley 414, one group of the 9 groups of blade shafts is a lengthened spiral rotary tillage blade shaft, the top end of the lengthened spiral rotary tillage blade shaft is provided with a belt pulley, which is locked by a top pin, the motor 401 is connected with the lengthened spiral rotary tillage blade shaft through a belt, the motor 401 works to drive the lengthened spiral rotary tillage blade shaft to work, the spiral rotary tillage blade 407 is driven to work through chain transmission, the left and right ends of the fixed plate 409 are provided with two angle adjusting bearings 410 fixed by bolts, the horizontal shaft 402 is fixed with the angle adjusting bearing 410 by a top pin.

[0031] When the rotary tillage operation is not performed, the rotary tillage working part 4 is in a retracted state. When it is necessary to transfer the position, the depth adjusting electric push rod 6 is controlled through the depth adjusting mechanism to retract the four-bar linkage 7, so as to drive the rotary tillage working part 4 to be off the ground, so that the rotary tillage blade 407 is separated from the ground, and the rotary tillage blade is prevented from being scraped with the ground during the transfer process.

[0032] When the rotary tillage operation is to be performed, the hub motor 3 is controlled through the remote controller, and the rotary tiller is remotely controlled to the front of the working land.

[0033] The motor 401 is inputted with a signal through the remote controller, the motor 401 rotates to drive the sprocket 404 and the chain 405 to rotate, the sprocket 404 is connected with the spiral rotary tillage blade shaft 406, so as to drive the spiral rotary tillage blade shaft 406 to rotate, the spiral rotary tillage blade shaft 406 and the spiral rotary tillage blade 407 are limited by the buckle and the round nut 408, the rotation of the spiral rotary tillage blade shaft drives the rotation of the spiral rotary tillage blade.

[0034] A forward signal is transmitted to the hub motor through the remote controller. The depth adjusting electric push rod 6 is inputted with a signal to drive it to extend, the extension of the depth adjusting electric push rod 6 drives the downward movement of the four-bar linkage 7, the downward movement of the four-bar linkage drives the rotary tillage working part 4 to move downward to approach the working land.

[0035] As the rotary tiller moves forward, the four-link linkage drives the rotary tillage working component 4 downwards. (Reference) Figure 6 The rotary tiller blade 407 gradually moves towards the soil. The working depth range of the rotary tiller blade 407 is 0-15cm, and the working depth range can be adjusted by controlling the tillage depth adjustment electric push rod 6, thereby adapting to the tillage requirements of different crops.

[0036] The resistance encountered by the rotary tiller blade 407 varies depending on the soil hardness. If the soil is hard, the rotary tiller blade 407 will experience greater resistance when moving vertically downwards and horizontally, making it difficult to work effectively. In this case, the angle of entry of the rotary tiller blade 407 into the soil can be changed by adjusting the electric push rod 8 to adjust the tillage angle.

[0037] The rotary tillage angle is adjusted by controlling the extension and retraction of the angle adjustment electric push rod 8, which in turn adjusts the angle of the rotary tillage working component 4. Controlling the extension and retraction of the angle adjustment electric push rod 8 causes the rotary tillage working component 4 to rotate around the horizontal axis 402. (Reference) Figure 7 This allows for angle adjustment of the rotary tillage working component 4.

[0038] For soils of varying hardness, the angle of the working component is adjusted by adjusting the electric actuator 8 to determine the appropriate entry angle of the rotary tiller blades 407 into the soil. The hub motor drives the rotary tiller forward, and the rotary tillage working component 4 performs the rotary tillage operation.

[0039] When a rotary tiller completes a row of rotary tillage, due to the limited space inside the greenhouse, it may not be able to perform row-changing operations by turning around. For a self-propelled small spiral rotary tiller with adjustable tillage depth and angle, the hub motor 3 can be adjusted from 0 to 90° by controlling the steering mechanism 2 to perform translation row-changing operations.

[0040] Perform translation and line wrapping operations, refer to Figure 11 When the rotary tiller moves from position ① to position ②, the rotary tiller has completed one row of work. At this time, it is necessary to switch to another row. First, disconnect the motor power, adjust the tillage depth adjustment electric push rod, and then drive the working parts to retract through the four-link.

[0041] By controlling the steering actuator 204, a signal is input to the steering actuator 204, causing it to rotate from 0 to 90°. The rotation of the steering actuator 204 drives the hub motor 3 to rotate. Figure 10 When the hub motor 3 rotates from ② to ③, the hub motor 3 is controlled to drive the rotary tiller to move. The position of the rotary tiller moves from ③ to ④. Then, the steering actuator 204 is controlled to input a signal to the steering actuator 204, so that it rotates from 90° to 0°. When the hub motor 3 rotates from ④ to ⑤, the rotary tiller completes the row change operation.

[0042] The direction of the wheel hub motor 3 is changed from ④ to ⑤, and the rotary cultivator completes the row changing operation, and the rotary cultivator is moved from ⑤ to ⑥, at this time, the rotary cultivator completes the rotary cultivation operation of another row, and so on, the working land is divided into rows for rotary cultivation, and the rotary cultivation operation is completed.

[0043] After the rotary cultivation operation is completed, the motor power is turned off through the remote controller, so that the rotary cultivator stops working, the depth adjusting electric push rod 6 is controlled to input a signal, so that the depth adjusting electric push rod 6 is driven to be retracted, the working part is driven to be retracted upward and away from the ground, the extension of the angle adjusting electric push rod 8 is controlled, so that the angle of the working part of the rotary cultivator is adjusted, and the angle is adjusted to be horizontal.

[0044] The specific embodiments of the application are described in detail above with reference to the drawings, but the application is not limited to the above-mentioned embodiments, various changes and improvements can be made to the application without departing from the spirit and scope of the application, and these changes and improvements all fall within the scope of the application. The scope of protection of the application is defined by the appended claims and their equivalents.
