Melon seed winnowing device

Abstract

The invention discloses a melon seed winnowing device, and belongs to the technical field of melon seed production and processing. The device comprises a bottom plate, wherein a box body is fixedly connected to the upper end surface of the bottom plate; a feed port and a motor are arranged on the upper end surface of the box body; the motor is located at the right side of the feed port; the outputend of the motor penetrates through the upper end surface of the box body and extends into the box body; a stirring rod drives stirring blades to stir melon seeds in the box body, so that dust and small-particle impurities mixed in the melon seeds are in a floating state, meanwhile, a fan is started, the fan blows air into the box body through an air inlet, and the fan blows the dust and the impurities into a dust receiving bag through an air outlet in the left side to be collected, so that the fine dust and the small-particle impurities in the melon seeds can be filtered out conveniently, the filtering effect is greatly improved, and the problems that an existing melon seed winnowing device cannot well screen out the fine dust and the impurities in the melon seeds, the screening effect is poor, the structure is complex, the production cost is high, and popularization is not facilitated are solved.

Description

technical field [0001] The invention relates to the technical field of production and processing of melon seeds, in particular to a melon seed winnowing device. Background technique [0002] Wind separation, as the name suggests, uses wind power to sort materials to achieve the purpose of removing impurities. The scientific point is to use the difference in aerodynamic properties between materials and impurities to remove impurities through the action of airflow. Depending on the direction of the wind, the air selection method can be divided into three types: vertical air flow air selection, horizontal air flow air selection and oblique air flow air selection. The idea of ​​this method is very simple. For example, after the wheat has been harvested, the grains and husks have been separated after being rolled, and then people will carry out the raising field, that is, when the weather is windy and the wind is suitable, the wheat is raised with a wooden shovel. Wind separatio...
