A storage and unloading grain box and a combine harvester

Abstract

The invention provides a grain storage and unloading box and a combine harvester, comprising a grain box shell, a grain outlet control device and a surplus grain collection device, the bottom of the grain box shell is provided with a grain outlet; the grain outlet control device controls the grain box The opening and closing of the grain outlet of the shell; the surplus grain collecting device is located under the bottom of the grain tank shell, and is used to collect different types of surplus grain in the grain tank shell and store them separately. The invention collects the surplus grain through the surplus grain collecting device, and can temporarily store the surplus grain in the grain box, so that the grain combine harvester can continue to harvest other different kinds of grains. The sorting device is used to distribute different kinds of crops into the designated grain storage room of the grain box. The invention solves the problems of unclean grain unloading, mixed species of grain and the like.

Description

technical field [0001] The invention belongs to the technical field of combine harvester grain boxes, and in particular relates to a storage and unloading grain box and a combine harvester. Background technique [0002] With the continuous development and popularization of harvesting machinery in agriculture, people have higher and higher requirements for the comprehensive performance of harvesting machinery. The grain boxes of existing harvesting machinery on the market are not clean when unloading grain, which wastes A large amount of grain reduces the economic income of farmers. In addition, when the grain combine harvester harvests different types of grain seeds, the phenomenon of mixed species often occurs, which leads to a great reduction in harvesting efficiency and overall machine reliability. It is of great significance to reduce the loss rate of grain and the phenomenon of mixed planting when unloading grain in the grain tank to improve the economic benefit of cro...

AI Technical Summary

Problems solved by technology

[0004] The above invention patents can complete the unloading of grain tanks, but still do not consider the problems of unclean unloading and mixed species of grain, and the structure is complex, the cost is high, and the reliability is often low in harsh working environments.
