[0002] Rice is the main food crop in China. Rice production is an important part of food production. After years of practice and promotion, the mechanized transplanting of rice has been widely recognized in terms of increasing rice yield and operation efficiency. The demand for paddy field pulping machines used for paddy field leveling is increasing year by year. The paddy field pulping machine is used in conjunction with a tractor to solve the problem of full straw return to the field at one time and avoid the problem of environmental pollution caused by burning straw. Early tillage mainly realizes the function of deep plowing and burying stubble. During wet tillage, deep plowing and burying stubble, stirring slurry, and leveling operations are carried out to meet the requirements of transplanting. The leveling function is mainly realized by a leveling plate. However, due to historical and geographical reasons, the arable land in many parts of China is very uneven, and the roads of these arable lands are narrow. Therefore, it is difficult for the leveling plate of a large paddy field pulping machine with a large length to enter the operation, while the leveling efficiency of the leveling plate of a small paddy field pulping machine is relatively low.
