Description

Rotary-sifting watermill polishing machine for rice

Technical field

The utility model relates to the rice polishing machine, especially a kind of rotary-sifting watermill polishing machine for rice.

Background technology

The watermill polishing machine for rice of producing mainly contains horizontal and vertical two big classes both at home and abroad, they all are to adopt traditional gravity flow screen polishing technology, sieve sheet and screen frame (unit) composition polishing room are fixed in the casing, polishing roll is in polishing room's high speed rotation, after rice enters polishing room from hopper, polishing roll drives rice and rolls, below polishing room, then stay a slice " dead band ", the minimum part of rice that enters " dead band " can obtain friction polishing or semipolish, the most grain of rice is forward impelling under the effect of conveyer, linearly extrude and can't polish, the whole polishing rate of using the machine rice reduces.Rice is when driving with polishing roll, form static friction in fixing polishing room, polishing roll direct collision rice makes broken rice rate height, secondly, depend merely on the running effect of polishing roll in gravity flow screen, rice can not get fully rolling in polishing room, makes the heat of rice friction heating not enough, rice water not really even, the part rice surface is difficult to form the gelatinization layer, and fineness and poor transparency have had a strong impact on the quality of finish of rice.For this reason, a lot of rice processing factories all adopt two or three watermill polishing machine for rice to link to improve quality of finish, so just increased production cost greatly, increased broken rice rate, also reduced rice milling yield.

Summary of the invention

The purpose of this utility model just provides a kind of polishing rate, rice milling yield height, less energy consumption, rotary-sifting watermill polishing machine for rice that broken rice rate is low.

Rotary-sifting watermill polishing machine for rice of the present utility model comprises frame, bran-collecting bucket, discharging opening, main shaft, polishing roll, helical feed roller and rice huller screen, be characterized in: the inside of main shaft is cavity, atomizing water pipe one end is inserted in the cavity, the other end joins with the atomizing water source outside main shaft, main shaft is by the feed shaft bearing, discharging bearing block and bearing fixing are on frame, rice huller screen carriage and rice huller screen all are nested with on main shaft, rice huller screen carriage and rice huller screen are affixed, one end of rice huller screen carriage is connected with driven gear, the other end links to each other with the charging lining, the charging lining, driven gear is enclosed within main shaft feed shaft bearing respectively, on the bearing in the discharging bearing block, have the through hole that communicates with cavities wherein on the main shaft in the rice huller screen, also be connected with polishing roll simultaneously, also have the through hole of water outlet on the polishing roll, polishing roll is the helical teeth polishing roll by feed end, is the straight-tooth polishing roll by discharge end; Hopper joins by the material mouth on feed pipe and the feed shaft bearing, is connected with the helical feed roller on the main shaft of charging lining and feed shaft bearing material mouth section; One end end of main shaft links to each other with the main transmission belt wheel, belt wheel is equipped with in other end end, and link to each other with decelerator by conveyer belt, on the output shaft of decelerator driving gear is housed, driving gear is meshed with driven gear on the rice huller screen carriage, the rice huller screen carriage is driven with main shaft by driving gear, driven gear and does rotatablely moving of different speed in the same way, and the sidewall of rice huller screen carriage is by supporting pulley support, and bran-collecting bucket is arranged on the below of rice huller screen.

When rotary-sifting watermill polishing machine for rice of the present utility model is worked, motor is by belt-driven main transmission belt wheel, polishing roll and conveying roller on main shaft and the main shaft are rotated at a high speed, belt wheel by rear-end of spindle simultaneously, change decelerator and drive driving gear, driving gear drives rice huller screen carriage and rice huller screen by driven gear, make it to do the rotation of different speed in the same way with polishing roll, the polishing roll high speed rotating, rice huller screen slowly rotates, like this, and after rice enters rice huller screen, because the slow rotation of rice huller screen, rice gently turning over again and again in rice huller screen, polishing roll be in the rice high speed motion that does not stop to roll, and thoroughly eliminated the conventional fixed sieve can stay " dead band " in polishing room drawback.Exactly because rice huller screen and polishing roll move in the same way, the row of rice has been carried out to dynamic friction, reduced flow resistance, reduced power consumption, meanwhile, rice has obtained rolling fully in rice huller screen, the also relative increase of contact friction frequency of the grain of rice and the grain of rice, enter the rice from the through hole of atomized water on main shaft and polishing roll of atomizing water pipe ejection, it is also even especially to make rice surface water, has improved the polishing effect of rice greatly.

Rotary-sifting watermill polishing machine for rice of the present utility model also has polishing rate, rice milling yield height and the low characteristics of broken rice rate simultaneously.
