Equipment for carrying out husked rice separation for rice by virtue of gas convection force

Abstract

The invention relates to the technical field of rice processing, and discloses equipment for carrying out husked rice separation for rice by virtue of a gas convection force. The equipment for carrying out husked rice separation for rice by virtue of the gas convection force comprises a shell body, wherein sliding rails are arranged on the two side walls in the shell body separately; inclined plates are movably connected to the surfaces of the sliding rails; rotating shafts are movably connected to the surfaces of the inclined plates; pull ropes are movably connected to the surfaces of the rotating shafts; reciprocating springs are movably connected to the ends, away from the rotating shafts, of the pull ropes; force storage teeth are movably connected to the ends, away from the pull ropes, of the reciprocating springs; meshing rods are movably connected to the bottoms of the force storage teeth; fan blades are movably connected to the bottoms of the meshing rods; supporting channels are movably connected to the bottoms of the inclined plates and located in the surfaces of the fan blades; buffering springs are movably connected into the supporting channels; and a screening groove is formed in the separating plate. Along with continuous shortening of the moving strokes of the reciprocating springs, the rotating speeds of the fan blades are in direct proportion to the amount of rice falling into the shell body, and therefore the effect that convection gas is generated through a shaking force to promote impurities to be separated from the rice is achieved.

Description

technical field [0001] The invention relates to the technical field of rice processing, in particular to a device for separating rice paddy by gas convection force. Background technique [0002] Rice is an indispensable staple food in people's daily diet. After rice grows and matures, it needs to go through multiple steps of processing. The general process is raw grain cleaning, husking, separation of rice and brown mixture, rice milling, white rice grading, etc., in which the rice and rice mixture is separated The steps determine the type of rice in the later stage and the technical level of the main processing process. [0003] Vibration and screening equipment is often used for the separation of existing rice-grass mixture. Although the technology of this type of equipment is relatively mature, the vibration and screening equipment will destroy the formed and good-looking rice grains during the shaking process, and rely solely on the shaking force It can only shake the p...

Problems solved by technology

[0003] Vibration and screening equipment is often used for the separation of existing rice-grass mixture. Although the technology of this type of equipment is relatively mature, the vibration and screening equipment will destroy the formed and good-looking rice grains during the shaking process, and rely solely on the shaking force It can only loosen other plants except rice, but it can’t really separate the two completely, so it needs to repeat multiple subsequent processes. Therefore, a device that uses gas convection force to separate rice paddy came into being.
