Description

Under feed vertical whitener for rice with germ

The utility model relates to the Cereals Processing Machines field.Be mainly used in processing plumule polished rice, also can be used for processing the rice polisher of long-grained nonglutinous rice or polished rice.

At present, the horizontal rice polisher of domestic main employing.Can be divided into the pressure wiping by operation principle and grind the formula of cutting two big classes from formula and speed.Pressure is wiped and is used for process japonica rice from formula more; Speed is ground the formula of cutting and is used for processing long-grained nonglutinous rice or long-grained rice more.The horizontal rice polisher of above-mentioned two classes adopts flat feeding to clear, and cracks rice easily.

The purpose of this utility model provides a kind of generation less vertical down feeding that can keep plumule of cracking rice and goes up and discharge rice polisher.

The purpose of this utility model is achieved in that

Adopt to rely on the deadweight feeding manner, brown rice enters auger conveyor, forces feeding from lower to upper by auger conveyor again.That is: brown rice relies on gravity to enter auger conveyor 14 through hopper 5, and motor 1 drives auger conveyor 14 and sand roller 6 through V belt, makes the brown rice of injection, carries from lower to upper, cut and pure white by grinding of sand roller.Discharge the hole of the screen cloth of rice bran on being fixed on screen frames 13, and be drawn to cyclone separator and collect by inhaling chaff blower fan 22.The top of sand roller 6 is rice distributing rollers 7, and it can strengthen the friction between the grain of rice, makes a meter any surface finish, has helped the discharge of rice simultaneously again.One pressure door 11 is arranged on the rice outlet seat, and it is made of pressure door-plate 21, counterweight and weight linear meter, regulates the position of counterweight on weight linear meter, can be used to control out the speed of rice and the pure white degree of rice.In order to keep the stable of main shaft, reduce the vibration of machine, except that 3,4 supportings of two bearings are housed, also install an aiding support bearing 8 additional at the main shaft top below main shaft.Because the rice machine adopts feeding down to go up and discharges the vertical working mode, so it is little to bear pressure, and evenly, the plumule of rice is difficult for broken, is difficult for dropping.

Below in conjunction with accompanying drawing concrete structure of the present utility model is described in further detail.

Accompanying drawing 1 is the utility model structure chart.

Accompanying drawing 2 is the utility model component diagram.

Accompanying drawing 3 the utility model pressure door schematic diagrames.

Concrete structure of the present utility model is described below:

As shown in Figure 1, 2, 3, the utility model is mainly by the aiding support bearing 8 at motor 1, main shaft 2, hopper 5, sand roller 6, auger conveyor 14, screen frames 13 and inner semicircle sieve thereof, rice distributing roller 7, rice outlet seat 10, pressure door 11, rice-supplying slot 12, main shaft below two block bearings 3 and 4, main shaft top with inhale chaff blower fan 22 etc. and form.

Motor 1 is connected the belt pulley of main shaft 2 lower ends by belt; Bearing spider 15 is fixed on the support 16; Block bearing 3,4 is set in main shaft 2 bottoms, makes main shaft be in plumbness.Recessed seam 17 is arranged on the ring flange of its underpart, and the location of matching with the protrusion seam 18 of bearing 4 bearing upper flange is to guarantee the concentricity of its centre bore; Auger conveyor 14 is keyed on the main shaft 2.Auger conveyor 14 is provided with hopper 5, and sand roller 6 is installed in its top, and the periphery outside of sand roller 6 is screen frames 13, and screen frames inside is two semicircle sieves, and its outside is close on the inner peripheral surface of screen frames.The top of the bottom of screen frames and auger conveyor housing equally also is located by connecting with concavo-convex seam; The ring flange of screen frames 13 upper flange dishes and rice outlet seat 10 also is located by connecting with concavo-convex seam; Rice distributing roller 7 is installed in the top of sand roller 6; Locking nut 9 is equipped with in rice distributing roller 7 tops, makes the rotation that tightly is fixed as one together of rice distributing roller, sand roller and auger conveyor, and the top of locking nut 9 is a main shaft top auxiliary bearing 8, more than all parts all be sleeved on the main shaft 2.The outer ring of auxiliary bearing 8 is fixed on the rice outlet seat 10, one side of rice outlet seat has an opening to be connected with rice output outlet groove 12, and be provided with pressure door 11 at this place, it is by slip counterweight 19, weight linear meter 20 and door-plate 21 are formed, slip counterweight 19 is sleeved on the weight linear meter 20, and weight linear meter 20 is packed on the door-plate 21, and door-plate 21 is hinged on the rice outlet seat 10.Suction chaff blower fan 22, pipeline and cyclone separator that the rice bran gathering system is installed by the belt pulley top of main shaft 2 are formed (not drawing among the figure).

The utility model has the advantages that in the lower feeding and discharge that during work, more horizontal pressure is little, and all Even, the grain of rice in the pure white process of limit, has certain shaping operation at Bian Shangsheng, and plumule is not vulnerable to sand The collision of roller, just the outer surface of rice is subjected to grinding of sand roller and cuts, so the grain of rice is difficult for brokenly, and plumule is also Be difficult for dropping; The stressed equalization of grain of rice colony of any direction of rice roller during the husk rice of this machine, and horizontal rice whitening machine Stressed big, the easy generation of the grain of rice colony of rice roller below cracked rice; Because the grain of rice is carried from lower to upper to produce and is rubbed The wiping effect has promoted any surface finish of rice, has improved the outward appearance grade of rice; In the husk rice of multimachine base connected type The time (rice germ must 4～6 machine seateds processing) because charging aperture is lower, rice output outlet is upper, Just in time the import of rear one machine is aimed in the outlet of last machine, needn't be again with elevator or human assistance, Province's equipment can save labor; If unit work can be aimed at hopper to rice output outlet, realize the automatic cycle work Already. Rice bran can not piled up at screen cloth, has overcome the shortcoming that rice bran is easily piled up in horizontal rice whitening machine sieve top; This machine general structure is simply compact, easy accessibility, convenient maintenance.
