Combine harvester grain unloading device

Abstract

The invention relates to a combine harvester grain unloading device which comprises a harvester body, a speed-controlled grain unloading barrel and a speed-controlled inner barrel. The speed-controlled grain unloading barrel is mounted at the left end of the harvester body, and the speed-controlled inner barrel is mounted in the speed-controlled grain unloading barrel. By the device, the problem that people generally need to lay a plastic bag on the ground to collect spilled crop grains as part of the crop grains spill in most cases when the bag is full caused by the fact that the crop grainsare conveyed at a constant speed when existing combine harvesters unload grains and the problem of waste caused by the fact that there is still a small part of the crop grains left in existing grain unloading equipment when grain unloading is completed can be solved. The device has the advantages of being capable of controlling conveying speed of the crop grains, slowing down the conveying speed before the bag is full to avoid spilling of part of the crop grains and shaking out the crop grains left in the equipment 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

[0007] 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.
