Abstract

The utility model discloses a vertical paddy pounder, which comprises a machine, a feeding device, a discharging device, a motor, a spiral conveyor driven by the motor through a transmission mechanism, and a whitening cylinder, wherein, a rice sieve and a chaff collection barrel are orderly arranged on the outside of the whitening cylinder. The utility model is characterized in that a cover is arranged in an elastic pressure door on the upper end of a whitening chamber; the pressure door is enclosed in a diversion storage with a discharging port. The utility model has the advantages of easy discharging and stable pressure of the whitening chamber. Besides, the pressure of the whitening chamber can be adjusted; the utility model can reduce broken rice rate by 10%.

Description

Vertical rice whitening machine

The utility model relates to a kind of vertical rice whitening machine, especially by means of roller processing watchcase brown rice is refined into the vertical rice whitening machine of commodity.

Chinese patent 93235370.3 discloses a kind of vertical rice whitening machine, the common prior art of it and the utility model comprises: frame charging/discharging device, motor and the auger conveyor and the roller that are driven through transmission mechanism by motor, roller are provided with rice huller screen and collection chaff tube outward successively.During work, cereal is from being positioned at the charging aperture input of whitening chamber bottom, and the grain of rice of completion of processing is discharged from the discharging opening on top.Problem is structurally, owing to adopt a hinged door in upper end outside in to cover discharging opening, and make door be in normally off with a lever with addition of ram, and and only depend on centrifugal force to back down the normal closed gate discharging from a direction, area of passage is little.Because discharging is not smooth, often causes the fluctuation of motor load electric current and whitening chamber internal pressure, even cause vexed car.

The purpose of this utility model is to provide a kind of vertical rice whitening machine, and it can guarantee to make discharging more unobstructed under the metastable situation of whitening chamber pressure.

The technical scheme that realizes the utility model purpose is: a kind of vertical rice whitening machine, and it is when comprising aforementioned formation, its distinctive feature is: have a lid to be loaded on the elastic pressure door of whitening chamber upper end, the water conservancy diversion storehouse with discharging opening is surrounded on pressure door in it.

And, pressure door can be in the form of annular discs, its lower limb is the inclined-plane, a vertical shaft is being interted in the center of pressure door, between vertical shaft and the pressure door every rolling element or bearing are housed, the outer suit of vertical shaft a spring, the nut of vertical shaft upper end through plane bearing with pressure mounting of the spring on pressure door, the bottom in water conservancy diversion storehouse tilts to the discharging opening direction down.

And, inhale the chaff blower fan and be connected with collection chaff tube through airduct, spray wind blower fan through airduct, main shaft axially in the radial hole of sky, main shaft and roller be connected with whitening chamber.

And, be provided with spiral between feed hopper and the auger conveyor and stir cage.

In the formation of this machine and since pressure door directly lid be loaded on the top of whitening chamber upper end, thereby all can discharging in the whole circumference of the two, promptly the area of passage of discharge is big, grain of rice stream is not turned back, so mobile smooth and easy; Again owing to can come regulating spring to act on the pretightning force of pressure door by nut, just can regulate whitening pressure and outlet pressure in the whitening chamber, avoid the motor load current fluctuation, so just the precision and the quality of grinding manufactured goods can be controlled accurately, stably and make broken rice rate reduce by 10% approximately.

The utility model is described in further detail below with reference to accompanying drawing.

Fig. 1 is the external form view of this machine.

Fig. 2 is the complete machine structure schematic diagram.

Fig. 3 is the partial enlarged drawing of pressure door.

With reference to Fig. 1～Fig. 3, this vertical rice whitening machine comprises frame 5, charging and discharging device 1,4, motor 21 and the auger conveyor 22 and the roller 20 that are driven through transmission mechanism 26 by motor 21, roller 20 outer rice huller screen 18 and the collection chaff tubes 7 of being provided with successively.Annular space between described roller 20 and the rice huller screen 18 is a whitening chamber 19.

Described motor 21 can be vertical or horizontal machine, when horizontal machine stands dressing, need add support 23.Like this, mainly be to consider when the client upgrades original meter machine, can keep original horizontal machine.

In order to finish task of the present utility model, be provided with the elastic pressure door 16 that a lid is loaded on whitening chamber 19 upper ends, the water conservancy diversion storehouse with discharging opening 17 is surrounded on pressure door 16 in it, and the bottom in water conservancy diversion storehouse 3 tilts to discharging opening 17 directions down.

Further constitute and be, pressure door 16 is in the form of annular discs, its lower limb is inclined-plane 10, a vertical shaft 13 is being interted in the center of pressure door 16, between vertical shaft 13 and the pressure door 16 every rolling element 11 or bearing are housed, vertical shaft 13 outer suits a spring 12, and the nut 14 of vertical shaft 13 upper ends is fitted in spring 12 on the pressure door 16 through plane bearing 15.At roller 20 depended on pressure doors 16 1 ends a smart roller 9 is set also preferably, has spiral bar 8 on the cylindrical of this essence roller 9, this will help the polishing processing of rice and rice can be discharged as early as possible, to prevent stone roller.During work, the rice stream that is the swirling flow attitude backs down and is pressure door 16 that elasticity presses down after the discharging opening 17 in water conservancy diversion storehouse 3 is discharged.

Can also be provided with and inhale chaff blower fan 29, this blower fan is connected with collection chaff tube 7 through airduct 6, spray wind blower fan 28 through airduct 27, main shaft 24 axially in the radial hole of sky, main shaft 24 and roller 20 be connected with whitening chamber 19.In order to help balanced charging, can between feed hopper 2 and auger conveyor 22, be provided with spiral and stir cage 25.Because these features itself all belong to prior art, so do not give unnecessary details.
