A grain unloading device for a combine harvester

Abstract

The invention relates to a grain unloading device for a combine harvester, which comprises a harvester body, a speed-controlling grain unloading cylinder and a speed-controlling inner cylinder. The left end of the harvester body is equipped with a speed-controlling grain unloading cylinder. A speed control inner cylinder is installed. The invention can solve the problem that when the existing combine harvester unloads grain, the grains of the crops are transported at a uniform speed. When the bag is full, some grains of the crops are often spilled, and the personnel usually lay a layer of plastic bags on the ground to collect the spilled grains of the crops. , when the grain unloading is completed, there are still a small part of the grains of the crops remaining in the existing grain unloading equipment, causing waste and other problems. It has the ability to control the conveying speed of the grains of the crops, slow down the conveying speed before the bag is full, and avoid some of the grains of the crops. The grains are spilled, and the grains of the crops remaining in the equipment are shaken out to avoid waste.

Description

technical field [0001] The invention relates to the field of agriculture, in particular to a grain unloading device for a combine harvester. Background technique [0002] A combine harvester is a combined machine for harvesting crops. The combine harvester combines harvesting and thresher in one piece, so that farmers can complete harvesting and threshing with a single operation, thus saving manpower and material resources, and greatly reducing the burden on farmers. burden in agricultural production. [0003] However, the existing combine harvesters have the following defects when unloading grain: 1. The existing harvesters transport the grains of the crops at a uniform speed. When the bag is full, some grains of the crops are often spilled, and the personnel usually lay a layer of plastic bags on the ground. Collect the spilled grains of crops; 2. When the grain unloading is completed, there are still a small number of grains of crops remaining in the existing grain unloa...

AI Technical Summary

Problems solved by technology

[0006] In order to solve the above problems, the present invention provides a combine harvester grain unloading device, which can solve the problem that when the existing combine harvester unloads grain, the ears and grains of the crops are transported at a uniform speed. Lay a layer of plastic bags on the ground to collect the spilled grains of the crops. When the unloading is completed, a small part of the grains of the crops will still remain in the existing grain unloading equipment, causing waste and other problems.
