Description

A bucket lift type grain selection machine

technical field

The utility model relates to the field of agricultural machinery, in particular to a bucket lift type grain sorting machine.

Background technique

With the continuous innovation and development of agricultural technology, the popularity of agricultural machinery has become more and more extensive. The use of agricultural machinery for grain planting and harvesting has become more and more popular among farmers, especially in recent years. Cleaning greatly reduces the labor load of farmers, improves labor efficiency, and enables the grain to be stored as soon as possible after harvest to ensure the quality of the grain. The post-harvest cleaning machine mainly adopts four cleaning principles: wind selection, screening, pocket selection and specific gravity selection, which can make the seeds achieve the selection effect. At present, the grain concentrators on the market still have the following deficiencies: (1) Since the grains are mainly fed by manual feeding or transported by conveyor belts before entering the concentrator, the labor intensity of manual feeding is relatively large, and the feeding is not constant, while When the material is loaded on the conveyor belt, the sundries will enter the selection machine with the grain, affecting the grain clarity; (2) Since the dust suction fan of the grain selection machine on the market is covered above the specific gravity screen, the vibration process of the specific gravity screen is sucked away by the dust suction fan When there is dust, it is not easy to suck away the dust and impurities mixed in the grain, and the impurities will enter the vibrating sieve with the specific gravity sieve, which makes the effect of grain removal and dust removal poor; (3) Due to the different types of grain, the required mesh screen The size of the holes is different. A single type of grain sorting machine on the market can only sort grains of similar size, and the screen cannot be replaced according to the size of the grains. Moreover, long-term sorting work will block the grains in the mesh screen holes, which is not convenient for screening. The sieve is cleaned in time, resulting in poor sorting effect of the grain concentrator.
