Grain storing and unloading box and combine harvester

Abstract

The invention provides a grain storing and unloading box and a combine harvester. The grain storing and unloading box comprises a grain box shell, a grain outlet controller and a surplus grain collector. A grain outlet is arranged at the bottom of the grain box shell, and the grain outlet controller controls opening and closing of the grain outlet of the grain box shell. The surplus grain collector below the bottom of the grain box shell is used for collecting different types of surplus grain of the grain box shell and separately storing the surplus grain. The surplus grain is collected by thesurplus grain collector, the surplus grain in the grain box can be stored temporally, the combine harvester continues to harvest other types of cereals conveniently, and a sorting device is used fordistributing different types of crops into a specific grain storage chamber of the grain box. The problems of non-thorough unloading, mixing of grain and the like are solved.

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.
