Problems solved by technology

[0002] At present, the modern plant protection operation of rice is usually carried out by self-propelled boom sprayer to improve labor efficiency and reduce labor intensity. When a larger sprayer works on this type of paddy field, the wheels are prone to subsidence and slippage. Insufficient friction and excessive rolling resistance from the paddy field mud become the main factors affecting the stability of the sprayer.
When a certain wheel of the sprayer sinks too deep in the paddy field, the forward resistance of the sprayer is too large, and the power of the driving wheel is not enough to overcome the rolling resistance from the muddy soil of the paddy field, and the sprayer will not be able to move forward even It is to increase the output power of the engine to overcome the rolling resistance of the mud, but it cannot solve the problem of insufficient friction. The wheels continue to slip in the depression, and the power distribution of the transmission system is affected when the wheels slip, resulting in deeper and deeper sinking.

Embodiment 1

[0064] The paddy field sprayer is moving forward in the farmland and spraying chemicals on the crops. Due to the complex road conditions such as mud puddles, deep footprints, and ridges on the ground, it is easy to cause inconsistent speeds of the four wheels of the sprayer. The soft clay in the paddy field has a high moisture content and adhesion Poor performance, high walking resistance, and rheological properties, the wheels are easy to slip or get stuck in the mud, which makes the sprayer unable to move forward stably.

[0065] To solve the above problems, such as Figure 3 to Figure 7 As shown, this embodiment provides a power adaptive adjustment device suitable for paddy field sprayers. The power adaptive adjustment device includes a power adjustment device 2, a subsidence detachment device 3, and an electronic control module. There are four power adjustment devices 2, The power adjustment device 2 is provided in one-to-one correspondence with the wheels 300. The output ...

Embodiment 2

[0085] This embodiment provides a paddy field sprayer, including the power adaptive adjustment device as described in the first embodiment, so as to ensure that the paddy field sprayer can move forward stably on the road.

[0086] Such as Figure 1 to Figure 4 As shown, the paddy field sprayer comprises a vehicle frame 100, a half axle 1, a spraying device 200 arranged on the vehicle frame 100 and four wheels 300 arranged at the bottom of the vehicle frame 100, wherein two wheels 300 are front wheels, and the other two The wheels 300 are rear wheels, and each wheel 300 is connected to the vehicle frame 100 through the half axle 1 .

[0087] The paddy field sprayer also includes engine 400, gearbox 4, differential 5, transmission shaft 6, speed reducer 7, electromagnetic clutch 8, half axle 1 connected with the front wheel is the front axle, and engine 400 can pass through gearbox 4 successively. , the differential 5 and the front axle transmit power to the front wheels, the h...

Embodiment 3

[0093] Such as Figure 8 As shown, this embodiment also provides a control method, the control method is used to control the paddy field sprayer as in the second embodiment, the paddy field sprayer includes the power adaptive adjustment device in the first embodiment, and the control method includes the following steps:

[0094] Step S100: the sensor detection system collects road condition data and sends the road condition data to the support vector machine through the industrial computer, and the support vector machine obtains the road condition classification result and the allowable range of the slip ratio according to the analysis of the road condition data.

[0095] Step S200: Obtain the slip ratio and torque ratio of the four wheels 300 through the sensor detection system, and determine whether the slip ratio of the wheels 300 exceeds the allowable range and whether the torque ratio of the wheels 300 exceeds the allowable range.

[0096] Step S300: If the slip ratio and...
