Problems solved by technology

[0002] At present, agricultural plant protection machinery is usually driven by people, and the body is heavy, and the supporting driving wheels are wide. It has the following problems: first, the body is heavy, and the passability of crop fields is poor; second, driving by people not only increases In addition to the weight, the pesticides applied often cause harm to people
Hefei Duojia Agricultural Technology Co., Ltd. disclosed a paddy field plant protection robot (patent number CN201420462253.6) and a new type of agricultural plant protection vehicle (patent number CN201420480907.8). They have good performance and will not cause harm to people, but they still have such problems in practical applications: 1. They all use ordinary hub motors as drive motors, but the torque of ordinary hub motors is not enough, and they can be used in muddy or uneven It is difficult to operate in the farmland, and it is difficult to drive the plant protection vehicle forward smoothly; second, they all need a steering device, and the steering gear or steering motor is used to drive the steering gear. Such a structure is more complicated, and the steering gear configured on a lightweight machine Or the torque of the motor is generally not large, but in muddy or uneven farmland, a large torque is needed to drive the steering, overloading the steering gear or the motor is easy to cause failure; third, the control method is complicated, not only to control the driving part , but also to control the steering servo (or motor) and brakes

Embodiment 1

[0035] Such as figure 1 , figure 2 , image 3 As shown, this embodiment adopts a brushless toothed motor 25 for driving. Wheel bracket 2 is installed on the bottom of vehicle frame 1; Left front wheel 3, right front wheel 4, left rear wheel 5, right rear wheel 6 are respectively installed on respective wheel bracket 2; On the four wheels of front wheel 3, right front wheel 4, left rear wheel 5, right rear wheel 6; Motor battery 7 is installed on four wheel supports 2 respectively, and motor battery 7 is respectively connected with the four wheels by wire The toothed brush motor 25 is connected to provide power for the operation of the brushless toothed motor 25; the pump battery 8, the medicine box 9, the pump 10, the spray rod bracket 11, and the main controller 17 are all installed on the top of the vehicle frame 1; the pump battery 8 is connected with the pump 10 by wires; the spray bar bracket 11 is installed on the rear of the vehicle frame 1; the spray bar 13 is inst...

Embodiment 2

[0038] Such as Figure 4 As shown, the difference from Embodiment 1 is that the drive mode is driven by a central motor 15, and the transmission mechanism uses a chain 19 to drive the wheels to rotate. Each middle motor 15 is equipped with one and the middle motor driver 16 and the two are connected with wires, and both are installed on the motor mount in the middle of each wheel support 2; On the rotating shaft, the large sprocket 20 is connected with each driving wheel by the shaft, and the small sprocket 18 is connected with the large sprocket 20 with a chain 19; each middle motor 15 is equipped with an independent motor battery 17, and the motor battery 17 is installed on Each wheel bracket 2 is directly above the vehicle frame 1 .

[0039] When the middle motor 15 rotates, the chain 19 is driven by the small sprocket 18, and the chain 19 drives the large sprocket 20 to rotate, and the large sprocket 20 drives each wheel to run. For other specific implementation manners,...

Embodiment 3

[0041] Such as Figure 5 As shown, the difference of this embodiment is that the chain transmission mechanism in the second embodiment is a shaft transmission mechanism. The transmission gearbox is fixed on the front wheel bracket 2, the middle motor 15 is fixed on the transmission gearbox, the first gear of the transmission gear 21 is fixed on the rotating shaft of the middle motor 15, and the gear at the end of the transmission gear 21 is Fixed transmission shaft 22, transmission shaft 22 runs through front wheel support 2, and the bottom end is fixed with transmission bevel gear 23, and driven bevel gear 24 is installed on each wheel by rotating shaft, and transmission bevel gear 23 meshes.

[0042] When the center motor 15 rotates, the transmission gear 21 drives the transmission shaft 22 to rotate. When the transmission shaft 22 rotates, the transmission bevel gear 23 at the bottom drives the driven bevel gear 24 to rotate, thereby driving the wheel to rotate. For other ...
