Rice hulling linkage and adjustment mechanism of household small grain processing machinery

Abstract

The invention discloses a rice hulling linkage and adjustment mechanism of household small grain processing machinery. The rice hulling linkage and adjustment mechanism comprises a main rubber roll, a subsidiary rubber roll and a tensioning wheel, and the design of the rice hulling linkage and adjustment mechanism is characterized in that a tensioning wheel shaft is pivoted onto the swinging end of a swinging arm of the tensioning wheel; the swinging arm of the tensioning wheel sleeves the main rubber roll; the subsidiary rubber roll is pivoted onto the swinging end of the swinging arm of the subsidiary rubber roll; the pivot of the swinging arm of the subsidiary rubber roll is movably hinged to the machine base of a rice hulling machine head; the swinging end of the swinging arm of the subsidiary rubber roll is further provided with a boss; the boss is pressed against the power arm of an adjustment lever; the middle pivot of the adjustment lever is movably hinged to the bottom of the shell of the rice hulling machine head; and the tail end of the resistance arm of the adjustment lever is elastically connected with the swinging end of the swinging arm of the tensioning wheel through a connection spring. The invention aims to provide the rice hulling linkage and adjustment mechanism of the household small grain processing machinery, so that the technical problems existing in a current rice huller that adjustment for a clearance between the rubber rolls is inconvenient; and the a grain guide-out passage in the material feeding hopper of the rice huller cannot be adjusted according to the change of the clearance between the rubber rolls are solved.

Description

technical field [0001] The invention relates to a grain processing technology equipment, in particular to a household small-scale grain processing machinery husking linkage adjustment mechanism. Background technique [0002] After the rice is purchased, it cannot be eaten directly by the user. It must first go through the process of hulling the rice to remove the chaff and make it into brown rice, and then through the process of rice milling to make the brown rice into polished rice before it can be eaten by the user. Therefore Husking is a very important process in rice processing. The rubber roller husker is the most commonly used husking machine at present. The gap between the two rubber rollers of the rubber roller husker directly affects the quality of the husking. If the gap is too large, the husking will not be possible. If the gap is too small, it will cause broken rice, and when the rubber rollers are used for a long time, the gap will change due to wear and the qua...
