Small seed wind separator

Abstract

The invention discloses a small seed wind separator and belongs to the field of agricultural machinery. A settling chamber is assembled on a rack in a vertically adjusted mode; a separation chamber and a fan are fixedly mounted on the settling chamber in sequence; an airflow guiding plate is fixedly mounted inside the settling chamber; an adjusting air door is rotatably mounted in the position, located at a fan air inlet, inside the settling chamber; an impurity collection box is rotatably mounted on the lower side of the settling chamber; a feeding hopper is fixedly mounted on the upper middle portion of the separation chamber; a feeding screen is assembled on the upper portion of the feeding hopper; a fan outlet is sleeved with a dust removal cloth bag; the separation chamber, the settling chamber, the fan and the impurity collection box form a closed airflow channel; four seed guiding strips are fixedly mounted inside the separation chamber horizontally in a mode of being staggeredsequentially from left to right; and the spacing distance ratio from top to bottom is 4:3:2; and the airflow guiding plate and the inner wall of the settling chamber have the inclined angle alpha of 50-70 degrees. The small seed wind separator is simple in structure, low in cost, small, light, free from seed mixing and rapid in separation, and the situation that seeds are damaged in separation isavoided.

Description

Technical field [0001] The invention belongs to the field of agricultural machinery, and relates to a seed cleaning machine, in particular to a small-sized seed wind cleaning machine. Background technique [0002] A small wind-powered seed cleaning machine is based on the different aerodynamic characteristics of the material, and uses the difference in resistance generated by the seed material and debris relative to the airflow to separate the debris mixed into the seed to improve the quality of the seeds. Seed cleanliness. [0003] At present, the domestic seed cleaning machinery is basically self-sufficient, but since most of the market is a complete set of seed processing equipment, its price is high, energy consumption is large, and there is a phenomenon of seed mixing, which cannot fully meet the requirements of small-scale seed production, especially It cannot adapt to the requirement of cleaning the seed quantity of a single plant and not mixing seeds. Therefore, th...
