Multi-stage grain drying system of combine harvester

Abstract

A multi-stage grain drying system of a combine harvester comprises an air blower, a heat exchanger, a starting and generation all-in-one machine, a vehicle-mounted battery, a lifting auger, far infrared heaters and a grain collecting box, wherein the heat exchanger is installed on an exhaust pipe of an internal combustion engine, an air inlet end of the heat exchanger is connected with the air blower, an air outlet end of the heat exchanger is connected with a hot air pipeline, one branch of the hot air pipeline is connected with the lifting auger, the other branch of the hot air pipeline is connected with the grain collecting box, the lifting auger is provided with a first-stage far infrared heater, the middle of the grain collecting box is designed to be of a throat shape, a second-stage far infrared heater is installed in the center of the throat, and the first-stage far infrared heater and the second-stage far infrared heater are connected with a front inverter, a rear inverter, the vehicle-mounted power battery and the starting and generation all-in-one machine through connecting lines. The multi-stage grain drying system of the combine harvester is directly embedded into a work component of the combine harvester, directly dries grains in the combine harvester, and has the advantages of being simple in structure, being low in cost and saving energy.

Description

technical field [0001] The invention relates to a multi-stage grain drying system of a combine harvester. Background technique [0002] At present, the main methods of grain drying in my country are natural drying and centralized drying of large grain drying equipment. The traditional natural drying method for grain drying is labor-intensive, time-consuming, takes up space, and even affects traffic. The centralized drying method of grain drying equipment requires centralized processing by farmers, which is difficult to meet the actual requirements of farmers, and due to the large scale of production, it leads to expensive equipment, high energy consumption and high cost. [0003] According to statistics, the loss of my country's grain in the process of threshing, drying, storage, transportation, processing, consumption, etc. is as high as about 18%. Among them, due to climate reasons, about 5% of these losses are due to the lack of time to dry the grain or the lack of safe...

AI Technical Summary

Problems solved by technology

Studies have shown that if grains are not dried quickly 10 hours after harvesting, 10% of them may become moldy, and 18 hours may have 30% moldy loss
