Abstract

The invention provides a cleaning and drying device and method and a harvester. The cleaning and drying device comprises an energy conversion device, an electric energy collecting and processing system, an electric energy flow direction control system, a storage battery, a vibrating screen heating device, a supporting device and a vibrating screen bearing rolling guide rail. The energy conversiondevice is used for converting pressure energy generated by reciprocating motion of a vibrating screen body into electric energy. The electric energy collecting and processing system is used for collecting the electric energy generated by the energy conversion device. The electric energy flow direction control system is used for judging whether the electric energy is used for charging the storage battery or for working of the vibrating screen heating device or not according to the SOC value of the storage battery and the actual working current of the vibrating screen heating device and whetherthe storage battery is used for providing electric energy for the vibrating screen heating device or not. Recycling and utilization of reciprocating motion energy of the vibrating screen are achieved,the collected energy is used for rice drying during cleaning of the cleaning device and charging of a vehicle-mounted storage battery, unnecessary energy waste in the cleaning process is reduced, andthe energy utilization and conversion efficiency is effectively improved.

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...
