Air guides, sieve panels with air guides and cleaners

Abstract

The invention discloses an air guide device, a sieve plate with an air guide device and a cleaning machine, relates to the field of agricultural machinery, and its main purpose is to solve the problem that the wind blown by the fan in the prior art cannot be evenly blown to the vibrating table surface Every corner leads to the problem that the seed stratification is not obvious and affects the cleaning quality of the seed. The main technical solution of the present invention is: the air guide device includes a body, a plurality of air guide grooves, and a plurality of air guide plates; a plurality of air guide grooves are arranged on the body; a plurality of air guide grooves include four parts The slots are the air guide slots at the feed inlet, the air guide slots at the discharge port, the light miscellaneous air guide slots and the heavy miscellaneous air guide slots; multiple air guide plates are arranged on the body, respectively located at the feed inlet air guide slots, In the light miscellaneous air duct and the heavy miscellaneous air duct; the air guide plate and the air duct form a certain angle according to the upwind direction. The invention is mainly used in the process of cleaning seeds by a seed cleaning machine.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to an air guide device, a sieve plate with the air guide device and a cleaning machine. Background technique [0002] Seed cleaning mainly removes foreign crop seeds, silt, stems, leaves, ears, stones, unfulfilled, insect-eaten, and fissioned seeds mixed in seeds, so as to improve seed purity, germination rate, and seed vitality. Therefore, seed cleaning is an important part of the seed work, an important means to realize the commercialization and standardization of seeds, and an important measure to improve the quality and technological content of seeds and increase agricultural production and income. [0003] At present, the cleaning of seeds is generally realized by a seed cleaning machine, which is usually designed to process wheat as a standard. The seeds are cleaned under the combined action of the reciprocating motion of the vibrating table and the airflow of the fan. T...

Problems solved by technology

[0004] But when the inventor implemented the above-mentioned technical scheme, he found that when the current seed cleaning machine was working, based on its existing structure, the fan could not evenly blow to every corner of the vibrating table, causing the seeds on the vibrating table to be unstable, The force is not uniform, so that the seed stratification is not obvious, which affects the cleaning quality of the seed
