A hand-tightening bolt is inserted into the interior of each group of the slots, and the hand-tightening bolt passes through the slots to form a threaded connection with the threaded hole.

[0013] Compared with the prior art, the advantages and positive effects of the utility model are:

[0014] 1.

It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0023] Embodiment 1, as Figure 1-Figure 4As shown, the utility model provides an intelligent obstacle avoidance system for a rotary tiller for orchard land preparation, including a rotary tiller body 1, a surface of the rotary tiller body 1 is provided with an intelligent obstacle avoidance component 2, the intelligent obstacle avoidance component 2 includes an operation box 201 and a notch 202, the operation box 201 is arranged on a side of the rotary tiller body 1 close to a seat, a notch 202 is provided inside one side of the operation box 201, a motor 208 is arranged inside the notch 202, an output end of the motor 208 is connected to a first gear 203, a surface of the first gear 203 is connected to a second gear 204, a steering wheel 205 is connected inside the second gear 204, and the rotary tiller body 1 is provided with an intelligent obstacle avoidance component 2. An infrared sensor 207 is connected to the center position of the front surface of the tiller body 1, and a PLC controller 206 is connected to the outer surface of one side of the rotary tiller body 1. The motor 208 and the infrared sensor 207 are electrically connected to the PLC controller 206. The output end of the motor 208 passes through the operating box 201 and is fixedly connected to the first gear 203. The position and size of the first gear 203 match the position and size of the second gear 204. The first gear 203 and the second gear 204 are meshed. The PLC controller 206 is electrically connected to an external power supply through a control switch.

[0024] The effect achieved by the entire embodiment 1 is that when the rotary tiller body 1 is tilling the land in the orchard and approaches an obstacle, the infrared sensor 207 will be sensed by infrared rays, and then the PLC controller 206 will automatically start the rotation function of the motor 208, thereby turning on the motor 208 and driving the first gear 203 to rotate through the output end. While the first gear 203 is rotating, it will also mesh and rotate with the second gear 204, and drive the steering wheel 205 to rotate, thereby allowing the rotary tiller body 1 to perform intelligent avoidance, thereby avoiding obstacles and avoiding the problems of mechanical damage or operation interruption caused by the lack of obstacle avoidance function when the existing rotary tiller body 1 is tilling the land in the orchard, thereby improving the safety of the rotary tiller body 1 during operation.

[0025] Embodiment 2, as Figure 2 and Figure 4 As shown, a dustproof heat dissipation component 3 is connected to one side of the slot 202, and the dustproof heat dissipation component 3 includes a threaded hole 301 and a fan 302. Four groups of threaded holes 301 are respectively opened at the four corners of the operation box 201 near the slot 202, and the fan 302 is connected to the inner wall of one side of the slot 202. A dustproof net 303 is connected to one side of the fan 302. Slots 304 are opened at the four corners of the dustproof net 303, and a hand-tightening bolt 305 is inserted into the interior of each group of slots 304. After the hand-tightening bolt 305 passes through the slot 304, it forms a threaded connection with the threaded hole 301.

[0026] The effect achieved by the entire embodiment 2 is that when the motor 208 is working, the fan 302 can be turned on to dissipate the heat of the motor 208, and the dustproof net 303 can isolate mosquitoes and dust in the orchard to prevent debris from adhering to the surface of the motor 208 and causing difficulty in dissipating the heat of the motor 208. When the dustproof net 303 needs to be disassembled and cleaned after long-term use, the hand-tightening bolts 305 can be rotated in the opposite direction, and all four groups of hand-tightening bolts 305 can be removed, and then the dustproof net 303 can be disassembled and cleaned. When installing the dustproof net 303, the hand-tightening bolts 305 can be passed through the slot 304 and then threadedly connected and fixed with the threaded hole 301. This can avoid high temperature when the motor 208 is used, thereby improving the service life of the motor 208.

[0027] Working principle: When the tiller body 1 approaches an obstacle, the infrared sensor 207 will be sensed, and then the PLC controller 206 will start the rotation function of the motor 208, so that the motor 208 drives the steering wheel 205 to rotate through the first gear 203 and the second gear 204 and drives the tiller body 1 to avoid the obstacle, thereby avoiding the obstacle and avoiding the problem that the existing tiller body 1 does not have the obstacle avoidance function and thus causes mechanical damage or operation interruption, thereby improving the safety of the tiller body 1 during operation. When the motor 208 is working, the fan 302 can be used to dissipate the heat, and the dust in the orchard can be isolated through the dustproof net 303 to prevent debris from adhering to the surface of the motor 208 and causing difficulty in heat dissipation of the motor 208.

[0028] The above are only preferred embodiments of the present invention and are not intended to limit the present invention in other forms. Any technician familiar with the profession may use the technical contents disclosed above to change or modify them into equivalent embodiments with equivalent changes and apply them to other fields. However, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention without departing from the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
