Abstract

The invention discloses a processing method for reducing tillage resistance of a furrow opener of a seeder, and relates to the technical field of agricultural machines. The processing method specifically comprises the following processes: 1, utilizing polyether-ether-ketone and sodium chloride particles for preparing porous polyether-ether-ketone; 2) adding the porous polyether-ether-ketone into asilicon nitride suspension, and calcining to obtain pretreated porous polyether-ether-ketone; 3) preparing pretreated zinc oxide powder; and 4) spraying a prepared powder coating on the surface of the cleaned furrow opener, and baking and curing to finish the treatment process. According to the processing method, the prepared powder coating is sprayed on the surface of the furrow opener, and theformed coating can reduce the sliding resistance of clay particles on the surface, so that the clay particles can easily slide off from the surface of the furrow opener, it is beneficial to realizingthe effect of reducing the viscosity and the resistance of the furrow opener during tillage, and thus the tillage efficiency of the furrow opener is further improved.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a processing method for reducing the tillage resistance of a seeder opener. Background technique [0002] During the mechanical interaction between soil and ground, the phenomenon of soil adhesion to the surface of soil-contacting parts is common. Soil adhesion will not only affect the working performance and quality of ground machinery, but even affect the normal operation and operation of machinery. In the field of agricultural engineering, soil adhesion increases the energy consumption of tillage parts by 30-50% during operation, increases the working resistance by more than 30%, and reduces the emergence of crops by 5-12%. With the modernization and development of agricultural machinery, the performance requirements for soil-contacting parts are getting higher and higher, and a new method of reducing viscosity and drag has become the development di...
