Grain selecting device

Abstract

The invention discloses a grain selection device, comprising a device body, a feed inlet and an ash outlet are respectively provided on the top and side walls of the device body, a feed channel is provided on the top inner wall of the device body, and The feed channel is located directly below the feed inlet, and a drive motor is fixedly installed in the side wall of the device body away from the ash outlet, and the output shaft of the drive motor is connected to one end of the first rotating shaft, and the other end of the first rotating shaft is One end is connected with a fan blade, a first gear is installed in the middle of the first rotating shaft, a bearing is fixedly installed on the inner wall of the bottom plate of the device body, a second rotating shaft is fixedly installed on the inner ring of the bearing, and the top of the second rotating shaft A second gear is installed. In the present invention, the dust and larger grain stones in the grain are removed through mechanical automation, which saves manpower and material resources, effectively improves the cleanliness of the grain, and facilitates the next step of processing. The device has a simple structure and novel design, and is worth popularizing.

Description

technical field [0001] The invention relates to the technical field of selection devices, in particular to a grain selection device. Background technique [0002] China is the world's largest grain producer and consumer, and with the improvement of species and yield increase, my country's grain output is gradually increasing. With the advancement of science and technology, agricultural mechanization has become popular. Traditional manual harvesting, mechanical harvesting of grain, and post-drying of grain are likely to cause dirt on the grain. Grain must go through various cleaning processes before storage or use. Such as dust removal, demagnetization, screening, drying and other cleaning work. [0003] In the process of harvesting, transportation and processing, grain will inevitably be mixed with some sundries, including soil dust, stones, rice husks and other grain core straws, etc. It is necessary to clean the sundries before processing to obtain clean Grain is traditi...
