The utility model relates to a kind of meter cutter abrasive roll rice polishing machine.

At present, traditional rice cutter abrasive roll rice polishing machine, has drive, bearing block, power transmission shaft, the helical feed head, rice milling roller, bar shaped husk rice cutter, the chaff of cracking rice sieve, upper encloser and support, upper encloser is provided with grain inlet and grain of rice outlet, upper encloser and support are fixedly connected, support is provided with cracks rice the chaff sieve and bar shaped husk rice cutter is housed, bearing block and support are fixedly connected, power transmission shaft is installed on the bearing block, one end of power transmission shaft is equipped with drive, and helical feed head and rice milling roller adjacent to each other are equipped with in the power transmission shaft middle part, have vertical convex tendon, rice milling roller on the cylindrical of rice milling roller main body, it also is the husk rice chamber that bar shaped husk rice cutter and upper encloser and the chaff of cracking rice sieve form the husk rice space with certain cross-sectional constriction.When this rice mill was worked, motor drove drive by belt, made power transmission shaft rotate; thereby make the helical feed head send into the husk rice chamber from the grain that grain inlet enters; like this, the vertical convex tendon on the rice milling roller main body cylindrical drives the grain revolution, in the radial section contraction place; grain is owing to extruding, friction between the vertical convex tendon that is subjected on bar shaped husk rice cutter and the rice milling roller main body cylindrical; thereby peel off husk and chaff skin, this rice mill, simple in structure; volume is little, and energy consumption is little.But; when grain is transported to rice milling roller from the helical feed head; when doing gyration with vertical convex tendon drive; because bar shaped husk rice cutter is the vertical bar shape, several convex tendons that have on the corresponding rice milling roller main body cylindrical also are longitudinally, make the place, convex tendon root dead angle of rice milling roller always have a small amount of grain; these grain are owing to be subjected to the protection at dead angle; though be squeezed,, cause the rice containing amount height because of the little not shelling of the amount of friction of rolling.For reducing rice containing amount, in practical operation, often pass through to regulate the gap between bar shaped husk rice cutter and the rice milling roller, i.e. the method for enlarging section amount of contraction, improve extruding and friction to grain, like this, though reduced rice containing amount, but cause broken rice rate to rise because of the cross-sectional constriction amount is excessive.

The grain of rice that the purpose of this utility model provides a kind of compact conformation production does not contain paddy and the low rice cutter abrasive roll rice polishing machine of broken rice rate.

The technical solution of the utility model is: a kind of have a drive, bearing block, power transmission shaft, the helical feed head, rice milling roller, bar shaped husk rice cutter, the chaff of cracking rice sieve, the rice cutter abrasive roll rice polishing machine of upper encloser and support, upper encloser and support are fixedly connected, support is provided with cracks rice the chaff sieve and bar shaped husk rice cutter is housed, bearing block and support are fixedly connected, power transmission shaft is installed on the bearing block, one end of power transmission shaft is equipped with drive, and helical feed head and rice milling roller adjacent to each other are equipped with in the power transmission shaft middle part, have vertical convex tendon on the cylindrical of rice milling roller main body, has convex shoulder on the bar shaped husk rice cutter, has and the corresponding circumferential slot of convex shoulder perhaps rice milling roller and helical feed head common formation and the corresponding circumferential slot of convex shoulder on the rice milling roller in the junction.

The utility model has the advantages that: (1) is simple in structure, compact, only on former rice mill rice milling roller and bar shaped husk rice cutter has been done suitable improvement; (2) grain that enters from grain inlet, after being input into the husk rice chamber by the helical feed head, because the convex shoulder of bar shaped husk rice cutter and the existence of corresponding circumferential slot, make the shelling of grain mainly carry out at the convex shoulder of bar shaped husk rice cutter and the annular shelling district of corresponding with it circumferential slot formation, at this moment the vertical convex tendon root dead angle on the rice milling roller main body cylindrical has not influenced to grain husking, so the shelling of grain relatively fully, evenly, the grain of rice of producing does not contain paddy; (3) because the rice mill after improving, annular region in bar shaped husk rice cutter convex shoulder and corresponding circumferential slot formation has made grain husking fully, evenly, and bar shaped husk rice cutter flat segments can make brown rice roll, rub again, and become polished rice, therefore, the gap that just do not need undue enlarging section amount of contraction in practical operation, promptly dwindles between rice milling roller and the bar shaped husk rice cutter reduces rice containing amount, and like this, broken rice rate just can be controlled on the lower level.
