[0069] Please refer to Figure 3, the drive module 30 includes four wheels 31, two motors 32, two speed reducers 33, four sprockets 34 and two chains 35. The motors 32, speed reducers 33, sprockets 34 and chains 35 are installed inside the chassis 61. The wheels 31 are connected to the speed reducers 33 through wheel shafts provided on the chassis 61 and the beam 611. Bearings are fixed at the corresponding positions on the inner and outer sides of the beam 611 to fix the wheels 31. The wheels 31 include two driving wheels 311 and two driven wheels 312. Each motor 32 drives a driving wheel 311 to rotate through a speed reducer 33 to drive the hybrid agricultural unmanned vehicle 100 to travel. The sprockets 34 and chains 35 are arranged inside the beam 611. Each sprocket 34 is sleeved on the shaft of a wheel 31. The two chains 35 are respectively installed on the left and right sprockets 34 for transmission, so that the driving wheels 311 drive the driven wheels 312 to rotate. The wheels 31 are driven by two independent motors 32 respectively, and the speed, turning, reversing and in-situ steering of the hybrid agricultural unmanned vehicle 100 are controlled by controlling the rotation speed and direction of the motors 32.

[0070] Please refer to Figure 2 , the control module 50 is responsible for receiving remote control signals and aggregating and transmitting various sensor data, and at the same time controlling the coordination and precise operation of each part of the hybrid agricultural unmanned vehicle 100. The control module 50 includes a main control computer 51, a power distribution box 52, a motor driver 53, a remote controller (not shown in the figure) and a camera (not shown in the figure).

[0071] Please refer to Figure 4, the power module 40 includes a generator 41 and a battery 42. The generator 41 includes an internal combustion engine 411 and a power generation disc 412. The internal combustion engine 411 and the power generation disc 412 are installed on the frame 62 and below the rear hood 632; the battery 42 is installed below the frame 62 and inside the chassis 61.

When the hybrid agricultural unmanned vehicle 100 is operating at low power, the surplus electric energy of the generator 41 can charge the battery 42; when the hybrid agricultural unmanned vehicle 100 needs to output high power, the battery 42 can also output electric energy at the same time to meet the power demand of the whole vehicle, achieving the purpose of continuous strong power and high control accuracy. In addition, when the fuel in the generator 41 stops working, the battery 42 can still directly provide electric energy for each module to maintain operation, and the space of the generator 41 can be replaced with an additional battery 42 to increase the electric energy storage capacity of the hybrid agricultural unmanned vehicle 100, so that the hybrid agricultural unmanned vehicle 100 becomes an agricultural unmanned vehicle driven by pure electricity.

[0072] Please refer to Figure 1 , it should be noted that a ventilation hole 6311 is provided at the front end of the front hood 631. Since the air inlet of the fan 21 is installed inside the hybrid agricultural unmanned vehicle 100 (inside the chassis 61 and below the frame 62), the air inlet sucks in external air from the ventilation hole 6311, which can simultaneously dissipate heat and cool down the internal structures such as the main control computer 51, the motor 32, the reducer 33, the motor driver 53, the water pump 12 and the generator 41 inside the hybrid agricultural unmanned vehicle 100.

[0076] It can be understood that when the hybrid agricultural unmanned vehicle 100 is used in agriculture, the spraying substances in the water tank 11 can be water, pesticides, leaf fertilizers, etc. The hybrid agricultural unmanned vehicle can also be used for spraying in other scenarios. In other embodiments, the hybrid agricultural unmanned vehicle 100 can have other numbers of air outlets 22, and the positions of the air outlets 22 can be set around the hybrid agricultural unmanned vehicle 100; the hybrid agricultural unmanned vehicle 100 can also change the four-wheel drive to six-wheel drive or eight-wheel drive by increasing the numbers of the driven wheels 312, sprockets 34 and chains 35, as well as the lengths of the chassis 61, beams 611 and cover plates 612, so as to achieve a higher load-carrying capacity; and the sprockets 34 and chains 35 can also be changed to belt pulleys and crawlers; the control system 50 can also add various other sensors to improve the accuracy of the hybrid agricultural unmanned vehicle 100 and expand other functions of the hybrid agricultural unmanned vehicle 100.

[0077] The hybrid agricultural unmanned vehicle 100 realizes the purpose of efficient agricultural spraying operation without a driver through the mutual cooperation among the spraying module 10, the air supply module 20, the driving module 30, the power module 40, the control module 50 and the vehicle body module 60, achieves the purpose of strong expandability of agricultural functions through the function expansion mechanism and the agricultural function expansion module 70, and realizes the purposes of sufficient power, high control accuracy, small volume, strong field entry performance and flexible expansion through the hybrid power of the internal combustion engine 411 and the power generation disk 412 and the pure electric drive of each module, so as to achieve the operation purpose of multi-purpose use of one machine in existing farmlands.
