Description
Technical field
The utility model relates to a kind of agricultural rice mill, relates in particular to a kind of self-checking device of rice mill rice milling roller.
Background technology
More crude fibre is contained in the cortical tissue of brown rice, directly edible husked rice will hinder the normal stool of human body, water imbibition and the dilatancy of brown rice are all poor simultaneously, edible quality is not good, and as cooked with brown rice, digestion time is long, ripe rice rate is low, color is dark, less sticky, mouthfeel is poor, therefore must be by the method for physics or chemistry, divest some or all of the cortex on brown rice surface, just can make it have excellent edible quality, and can improve its commodity value.Rice mill is exactly the machine of by mechanicals efforts, brown rice being removed the peel pearling.
Brown rice by feed hopper after flow control device enters whitening chamber, delivered to rice milling roller by spiral head and advance along rice milling roller surface spiral, stone roller is cut brown rice cortex, and make the grain of rice and the grain of rice, the mutual frictional impact of the grain of rice and rice huller screen, makes it open rough and pearling, simultaneously by the effect of spray wind, force rice bran to depart from the grain of rice, discharge sieve aperture.
Rice mill is mainly made up of feed arrangement, whitening chamber, discharge device, transmission device and spray wind system.Affecting rice mill husk rice effect has a variety of factors, for example, gap between the percent cracked rice of the kind of brown rice, the water content of brown rice, brown rice, rice cutter and cylinder, imports and exports coordinating of plug-in strip etc.
Drive greatly, export plug-in strip when import plug-in strip and close hour, whitening chamber grain increases, and its pressure increases, and grind cream-coloured white, but it is many to crack rice; Otherwise if import plug-in strip turns down, outlet plug-in strip is opened greatly, it is less that whitening chamber is deposited rice, and pressure decreased grinds the grain of rice just more coarse, and therefore the feed arrangement of rice mill is to husk rice quality important role.
Granted publication number is CN2271928, and Granted publication day is that the Chinese utility model patent on January 7th, 1998 discloses a kind of box rice minimill for grain of rice shelling, is especially convenient to peasant household and provides use for oneself.This machine by frame, cylindrical shell on it, cylindrical shell by the spiral propeller of arranging successively on motor-driven main shaft, main shaft and gear hobbing and blow chaff blower fan, high pressure positive blower forms, and has that volume is little, lightweight, easy to use, peasant household provides for oneself, do not go out door can push away the features such as new rice.
Granted publication number is CN03251087.X, Granted publication day is that the Chinese utility model patent on May 9th, 2003 discloses a kind of vertical household rice mill, comprise storage bin hopper, box-type casing, feeding whitening chamber, single-phase motor, rice output outlet, blow chaff air-blast device and chaff powder collector, above-mentioned feeding whitening chamber and single-phase motor are erect and are arranged in casing, in whitening chamber, there is husk rice iron roll, rice cutter, cylindrical shape rice huller screen, husk rice iron roll is positioned at the cylinder of cylindrical shape rice huller screen, its diameter is 44 ~ 120mm, there is feeding screw husk rice iron roll one end, rice cutter is welded on the inner periphery of cylindrical shape rice huller screen, the other end of iron roll is directly connected with the main shaft of single-phase motor, described chaff powder collector is to be provided with a cyclone at rice output outlet place, the side of above-mentioned box-type casing is provided with to open and stops button.This utility model volume is little, lightweight, adopts 220 volts of monophase machines to drive, and does not benefit from electric line restriction, is suitable for wide farmers and town and country grain shop and uses.
Above-mentioned utility model patent is in the time of husk rice, and paddy is sent into whitening chamber from feed hopper through spiral propeller and ground the shell and the surface fibre tissue that go to paddy surface.Paddy, due to the factor such as kind and growing environment, makes paddy granular size differ larger, and in order to reach good pearling effect, rice mill is according to the size of paddy particle, need to adjust the gap between rice huller screen and rice milling roller, the pressure that ensures whitening chamber with this, grinds the good grain of rice.And in the actual course of work, staff first regulates the gap between rice huller screen and rice milling roller according to husk rice effect, once after adjusting, just no longer regulate, and due to the reason of paddy granular size, may cause that paddy that particle diameter is large becomes cracks rice, and the less paddy pearling of particle diameter is not thorough, does not reach pearling requirement.
Utility model content
In order to overcome the defect of above-mentioned rice mill, the utility model provides a kind of rice mill rice milling roller self-checking device, this rice mill rice milling roller self-checking device can be according to the pressure in whitening chamber, automatically regulate the gap of rice milling roller and rice huller screen, ensure the pressure stability in whitening chamber, thereby make stone roller grain of rice broken rice amount out few, pearling is thorough, and pearling is effective.
In order to reach above-mentioned technical purpose, the technical solution adopted in the utility model is:
Rice mill rice milling roller self-checking device, it is characterized in that: comprise rice milling roller, pressure sensor, guide rail, controller and drive unit, described pressure sensor is arranged on rice milling roller, described rice milling roller is arranged on guide rail, described drive unit is used for driving rice milling roller to slide on guide rail, the signal input part of described controller is connected with pressure sensor, and the signal output part of described controller is connected with drive unit.
