Abstract

The invention provides a cleaning and drying device and method and a harvester, including an energy conversion device, an electric energy collection and processing system, an electric energy flow control system, a storage battery, a vibrating screen heating device, a supporting device and a vibrating screen bearing rolling guide; To convert the pressure energy generated by the reciprocating motion of the vibrating screen body into electrical energy, the electrical energy collection and processing system is used to collect the electrical energy generated by the energy conversion device, and the electrical energy flow control system is used to control the energy according to the SOC value of the battery and the heating device of the vibrating screen. The actual working current determines whether the electric energy is used for charging the battery or for the operation of the vibrating screen heating device, and whether to use the battery to provide electric energy for the vibrating screen heating device. The reciprocating motion energy of the vibrating screen is recovered and utilized, and the collected energy is used for rice drying during cleaning by the cleaning device and charging of the on-board battery, reducing unnecessary energy waste during the cleaning process and effectively improving energy utilization and conversion efficiency.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a cleaning and drying device and method and a harvester. Background technique [0002] When the crawler rice combine harvester is working, the vibrating screen screens the threshing grains through reciprocating motion. During the reciprocating motion, the rolling bearing on the vibrating screen will generate a lot of pressure on the guide rail, but the energy of this part is in the form of friction. The form of heat generation is dissipated, which also leads to low energy utilization efficiency of the combine harvester cleaning device, which causes a lot of waste to the combine harvester. Since the rice extraction mixture often has a high grain moisture content during cleaning, resulting in a decrease in subsequent cleaning efficiency, the cleaned grains can be cleaned by on-line drying. However, the online drying of grains in the cleaning process requ...
