CN2533945Y - Double-rolled rice miller - Google Patents

Abstract

The utility model provides a novel rice miller with double rollers, wherein, a rice milling roller with double rollers is arranged on a principal axis of a rice miller frame, rice bran mixture is conveyed into a separator after the rice is milled and uncoated, and an exhaust fan arranged on the frame uses the airflow produced by fan rotation to operate winnowing on the rice bran mixture in the separator. The utility model can realize milling and uncoating rice, removing bran by winnowing, separation and classification continuously for once. The utility model has the advantages of avoiding excessively high temperature of rice and reducing the rate of broken rice, greatly improving the comprehensive technical and economic targets of the rice miller.

Description

Novel pair of roller rice mill

The utility model belongs to the Cereals Processing Machines class, the novel roller of particularly a kind of rice mill.

We know: rice is processed in the paddy pearling must uses rice mill.China's widely used jet-air rice polisher in rural area mainly is made up of cabinet, cover, main shaft, roller, rice cutter, rice huller screen and spray wind system at present.Wherein roller is the rice mill critical piece, though roller commonly used can make present rice mill possess preferable performance, because its structure is not too reasonable, has influenced the further improvement of rice mill performance.Paddy in the shelling whitening chamber that the roller and the cabinet inner chamber of band shelling white gluten forms, under the acting in conjunction of shelling white gluten, rice cutter and rice huller screen through rolling, extruding, collision, friction etc. and the shelling pearling is processed to rice.It is smooth inadequately that material is advanced, and this just makes the cereal or the brown rice that diminish gradually reduce gradually in the suffered power of bran removal part, and unused power influences the crudy of rice.This traditional operating type work efficiency is low, labour intensity is big, the requirement of incompatibility agricultural production far away.Therefore, this roller affects the further raising of complete machine overall target.

The purpose of this utility model is developed exactly and a kind ofly can effectively be improved the rice crudy, satisfies the novel pair roller rice mills of people to two rollers of the more and more higher demand of rice quality requirement, four blade, four sieves.

The purpose of this utility model is achieved by following technical proposals: a kind of novel pair of roller rice mill, it mainly constitutes the coaxial double roll rice polisher roller of being made up of propeller and bran removal part by the rice milling chamber seat that coaxial pair of rice milling roller is installed in the motor, belt drive unit and the cabinet that are installed on the frame, rice milling chamber lid, the pearling process that will shell is divided into shelling and pearling polishing two procedures, and this two procedures is finished in the shelling chamber and the pearling polishing room of coaxial series connection respectively.Promptly device has the coaxial husk rice roller that is cascaded in same cabinet, makes it form shelling chamber and pearling polishing room with rice huller screen separately.Simultaneously, separator is installed on frame, the carrier pipe that is fixedly installed on the cabinet is inserted in the charging aperture of separator, the roller that drives when motor rotates on the main shaft rotates, also drive the air exhauster fan rotation that is installed on the frame simultaneously, the air-flow that fan is produced inserts in the air inlet of separator, and separator is separated into superior rice outlet, half-fine rice outlet and fine rice bran discharging opening by the multiple filtration net.

The two roller rice mills of the utility model have novel structure, and are easy and simple to handle, working stability, and dependability can be good, nominal power output height, processing advantages such as amount paddy is energy-conservation more than 30% together, and noise is little.Because the utility model adopts two rollers to finish paddy husking work, and roller is finished brown rice pearling work, sharing of load is even when making its work done simultaneously, improve the stressed of material widely, reduced the resistance of rice, broken rice rate is low, improved rice output, made selection by winnowing of chaff rice clean.Therefore make the rice that processes fair and clear bright and clean, broken rice rate is low, and temperature is low, anti-storage.

Below in conjunction with accompanying drawing the technical solution of the utility model is further elaborated:

Fig. 1 is a front view of the present utility model;

Fig. 2 is an A-A cutaway view of the present utility model;

Fig. 3 is a rice bran cyclone separator arrangement schematic diagram.

With reference to Fig. 1, above cabinet 3, be provided with hopper 1, the coaxial rice milling roller 4 and 5 that is in series is installed in the cabinet 3, two ends, the left and right sides are provided with respectively and advance muscle 6 and shelling muscle 7, white gluten 18 on rice milling roller 4 and 5, make its part and two rollers 4,5 rice huller screen 9 and 10 separately with cabinet 3 inner chambers form shell chamber and pearling polishing room respectively.Be provided with up and down two group of four rice huller screen 9,10 and four husk rice cuttves 11,13 on two rollers on the main shaft 8 simultaneously, Fig. 2 shell the top, chamber be provided with before rice huller screen 9 and below be provided with before rice cutter 11, the top is provided with back rice huller screen 10 and the below is provided with back meter cutter 13 polishing room in.It is work like this: paddy is poured in the hopper, starter motor, driven by motor main shaft 1 rotates beginning husk rice work, belt pulley on the main shaft 1 drives extractor fan work again by belt drive unit simultaneously, the rice bran mixture that stone roller is made is sent in the rice bran separator (Fig. 3) by carrier pipe, at this moment, the exhausting separator that is fixed on the frame is separated into superior rice discharging opening 14, half-fine rice discharging opening 16, thin rice discharging opening 17 with the rice bran mixture, realizes the purpose that rice bran separates selected rice.The utility model is novel, design ingenious, scientific structure, good separation effect.
