The controller is designed to be electrically connected to a remote control handle. The controller is activated by the remote control handle, and the two walking components are activated by the controller, thereby realizing automatic driving of the device. Compared with the existing technology, the operator only needs to stand on the side of the vegetation and does not need to push the device forward, which saves time and effort. At the same time, it prevents pesticides from being contaminated on the surface of the operator's clothes, reduces the harm caused by large amounts of pesticides inhaled into the human body, and improves the flexibility of the device. However, when the device is spraying pesticides, the range of the pesticide spraying is small, making it difficult to spray pesticides over a large range, and the spraying efficiency is low. Summary of the Invention

[0027] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show components related to the present invention.

[0028] like Figure 1 As shown, a novel orchard pesticide spraying crawler robot includes a bracket 1, an eccentric wheel mechanism 2 is fixed on the bracket 1, a pesticide spraying module 3 is movably connected to the bracket 1, and one end of the eccentric wheel mechanism 2 is connected to the bottom wall of the pesticide spraying module 3;

[0029] like Figure 3 As shown, the eccentric wheel mechanism 2 includes an eccentric wheel 21 and a motor 22. The motor 22 is fixed to the bracket 1. The output end of the motor 22 is connected to the eccentric wheel 21. The other end of the eccentric wheel 21 is connected to the bottom wall of the pesticide spraying module 3.

[0030] like Figure 2 As shown, the pesticide spraying module 3 includes a cylinder 31, a fan, turbine blades 33 and an atomizing nozzle 34. The bracket 1 is movably connected to the outer wall of the cylinder 31. The bottom end of the cylinder 31 is connected to the fan, and the top of the fan is rotatably connected to the turbine blades 33. Several atomizing nozzles 34 are centrally symmetrically installed on the inner wall of the cylinder 31, and the nozzles of the atomizing nozzles 34 are located above the turbine blades 33.

[0031] The cavity of the atomizing nozzle 34 is connected to the output end of the pump, and the input end of the pump is connected to the water tank 6;

[0032] The bracket 1 , the water tank 6 and the pump are mounted on a movable crawler chassis 4 .

[0033] It should be noted that when in use, the pesticide in the water tank 6 is pumped to the atomizing nozzle 34 for atomization treatment, and the turbine blades 33 are driven to rotate by the fan. Then, the atomized water mist is transmitted from the cylinder 31 by the air volume and pressure of the turbine blades 33. At the same time, the bottom wall of the pesticide spraying module 3 is connected to the eccentric wheel mechanism 2, which rotates the cylinder 31 connected thereto through eccentric motion, thereby achieving coverage of a larger area.

[0034] At the same time, in order to further increase the pesticide application area, the bracket 1, the water tank 6 and the crawler chassis 4 connected to the bottom of the pump are movable. By driving the crawler chassis 4 to move, the pesticide spraying module 3 can be moved to a farther place, so that the pesticide coverage area is wider and the application efficiency is higher.

[0035] Furthermore, Figure 4 As shown, a ring 5 is movably connected between the bracket 1 and the pesticide spraying module 3. Specifically, the bracket 1 is rotatably connected to the outer wall of the ring 5. A slide groove 51 is opened in the inner circumference direction of the ring 5, and the pesticide spraying module 3 is slidably connected in the slide groove 51.

[0036] It should be noted that the ring 5 can rotate on the bracket 1, and the outer surface of the pesticide spraying module 3 is connected to a limit rod, which slides in the slide groove 51 of the ring 5, so that the pesticide spraying module 3 can rotate in the circumferential direction of the ring 5. The eccentric wheel mechanism 2 drives the pesticide spraying module 3 to rotate in the ring 5. At the same time, the pesticide spraying module 3 rotates on the bracket 1 together with the ring 5, so that the opening of the cylinder 31 can be directed to a larger angle, thereby achieving a wider range of spraying of the atomized pesticide.

[0037] In the present invention, the angle between the eccentric mechanism 2 and the bottom wall of the bracket 1 is 45°-60°.

[0038] It should be noted that setting the angle between the eccentric wheel mechanism 2 and the bracket 1 to 45°-60° can make the pesticide spraying area wider. If the angle is too large, it is easy to cause the pesticide to be lost, resulting in pesticide waste. If the angle is too small, the pesticide spraying range will be too small.

[0039] In the present invention, the turbine blades 33 are spiral-shaped. The spiral-shaped turbine blades 33 can create a larger wind pressure, which can achieve a wider range of spraying effects when blowing towards the atomized pesticide.

[0040] In the present invention, the turbine blades 33 are made of stainless steel, which can reduce the damage to the turbine blades 33 caused by the atomized liquid during use.

[0041] like Figure 2 As shown, the nozzle of the atomizing nozzle 34 is bent, and the virtual extensions of the nozzles of several atomizing nozzles 34 intersect at one point.

[0042] It should be noted that the nozzle part of the atomizing nozzle 34 is curved, and the nozzle direction of the atomizing nozzle 34 virtually extends to intersect at one point, which makes it easier for the atomizing nozzle to atomize and spray the pesticide, and then the mist is gathered together, and then the gathered mist is blown out through the turbine fan blades 33, so that the atomized pesticide can be blown a longer distance.

[0043] The crawler chassis 4 includes a chassis body, left and right motors installed inside the chassis body, and a driver for driving the left and right motors to move. A crawler structure is movably connected to the chassis body, and the left and right motor output shafts are movably connected to the crawler structure.

[0044] It should be noted that when the pesticide spraying module 3 is working, the crawler chassis 4 can move. After the crawler chassis 4 moves, the pesticide sprayed through the pesticide spraying module 3 can cover a larger area, and the efficiency will be higher.

[0045] Furthermore, a remote control module is installed on the crawler chassis 4 to control the start and stop rotation of the left and right motors and the switch of the pump.

[0046] It should be noted that the remote control module consists of two parts: a handheld transmitter and a receiving terminal. The operator issues control commands by pressing buttons on the transmitter. The MCU (Microcontroller Unit) collects the corresponding control signals, encapsulates them into data packets, and then transmits the data packets to the receiving terminal via wireless radio frequency communication. At the receiving terminal, the microcontroller parses the data packets and outputs the corresponding control signals to the motor controller. This process enables remote wireless control, allowing the operator to control the device without direct contact. The control system receives the signals and then controls the operation of other modules.

[0047] Specifically, the control system uses an STM microcontroller, which controls the start and stop of the motor and the direction of rotation, allowing the crawler robot to flexibly move forward and backward. Furthermore, by controlling the pump on and off, the control system also operates the pesticide spraying module, enabling the robot to precisely spray pesticides in the orchard.

[0048] It should be added that a battery conditioning module is also provided in the crawler chassis 4. The battery conditioning module provides power support for other modules. It is mainly composed of a battery pack and a pressure reducing and voltage stabilizing module. The purpose of the pressure reducing and voltage stabilizing module is that the voltage provided by the battery pack is relatively large and cannot directly power the STM control system. It needs to be reduced in voltage before powering. After the voltage reduction process, the STM control system can obtain the appropriate voltage from the battery conditioning module and thus work normally.

[0049] When the utility model is used, the eccentric wheel mechanism performs eccentric movement to make the connected cylinder 31 slide in the slide groove 51 of the ring 5. At the same time, the ring 5 rotates on the bracket, so that the opening of the cylinder 31 can be oriented to more and larger angles. The pesticide is then atomized through the atomizing nozzles. Multiple atomizing nozzles spray water mist. The wind pressure generated by the fan and turbine blades 33 below the atomizing nozzles sprays the water mist from the opening of the cylinder 31, and the pesticide water mist is sprayed out through the opening of the cylinder 31.

[0050] The above description is based on the ideal embodiment of the present invention. Based on the above description, relevant personnel can make various changes and modifications without departing from the technical scope of the present invention. The technical scope of the present invention is not limited to the content of the specification, but must be determined according to the scope of the claims.
