Husking and separating integrated machine for unhusked rice

Abstract

The invention discloses a husking and separating integrated machine for unhusked rice. The machine is characterized in that a rotating plate is coaxially arranged below a fixed plate, and a rolling milling space is formed between the rotating plate and the fixed plate; a feeding channel is arranged in a rotating shaft of the rotating plate; a tapered rolling surface of which the outside diameter gradually decreases is arranged at the bottom part of the fixed plate; a tapered supporting surface which fits the tapered rolling surface is arranged on the top part of the rotating plate; a pluralityof rolling bumps and a plurality of sweeping brushes are arranged on the tapered rolling surface; a plurality of guide grooves which extend from the middle part of the rotating plate to the side edgeare formed in the top part of the tapered supporting surface; an air blower is used for blowing air below the rolling milling space through an air blowing chamber in the rotating plate. According tothe machine, the unhusked rice entering through a feeding pipe is twisted in the rolling milling space as the rotating plate rotates; and moreover, the unhusked rice is extruded toward the outer edgethrough the tapered shape of the rolling milling space; then the rolled and milled unhusked rice can be subjected to rice and husk separation through the sweeping brushes; and the husked rice is discharged through centrifugal force. With the adoption of the machine, the husking and separating is achieved; and the product processing accuracy is high.

Description

technical field [0001] The invention relates to the technical field of paddy shelling, in particular to a high-efficiency and thorough shelling equipment for paddy processing. Background technique [0002] Existing common paddy hulling machines have rubber roller type, sand disc type and centrifugal type etc. The rubber roller type uses the extrusion of two rubber rollers and the rubbing and tearing effect caused by the speed difference between the two rollers, so that the paddy can achieve the purpose of husking. The husking rate of the rubber roller type is high, the surface of the brown rice is smooth, and the broken rice is less, but the rubber roller wears quickly when the temperature is high, and the brown rice is more broken, and the production cost is higher. The sand disc type uses the upper and lower circular emery discs to hustle the rice through end pressure, rubbing and tearing. The advantage is that brown rice has less broken waist, the sand plate is more wea...
