Description

Full-automatic adjustable double roll rice polisher

Technical field

The utility model relates to a kind of rice mill, and especially a kind of full-automatic adjustable double roll rice polisher belongs to the Cereals Processing Machines technical field.

Background technology

Rice mill is the rice finish machining equipment of using always.Application number is called " iron rod strong punkah rice mill " for the 01263106.X name and application number discloses this kind equipment respectively for the Chinese patent application that the 200820033646.X name is called " two air channels rice mill ".These rice mills all have only a rice milling roller, in order to guarantee the husk rice quality, usually need two machine secondaries to roll processing, and are not only time-consuming, and waste energy.For this reason, application number is that 200920256592.8 Chinese patent application discloses a kind of further improved " double roll rice polisher ".

Yet the rice mill screen frame of above-mentioned prior art and the gap of iron roll are all unadjustable, therefore can't make the different rice of moisture content reach consistent crudy, the result is for the bigger rice of water content, usually need two machine secondaries to roll processing, not only time-consuming, and waste energy.

Summary of the invention

The purpose of this utility model is: the problem that exists at above-mentioned prior art, by architecture advances, proposes a kind of can be by regulating, make the different water cut rate rice process the full-automatic adjustable double roll rice polisher that all can reach the basically identical desirable quality.

In order to reach above purpose, full-automatic adjustable double roll rice polisher of the present utility model comprises axle and lower shaft on the level that is supported on the frame, described upward axle and lower shaft are installed motor-driven horizontally-arranged lift respectively according to the order of sequence, the spiral propeller of circumferential constraint, (iron roll is industry generic term to have the iron roll of tapering, and non-limiting material) and withstand on the back-moving spring of iron roll end face, the harness of described iron roll overcoat has the fixedly screen frame of the tapering that matches with it, be equipped with respectively and the relatively-stationary charging seat of frame and feed hopper described top of going up axle and lower shaft auger conveyor, described go up be equipped with respectively below axle and the lower shaft back-moving spring relatively-stationary with frame on, following rice output mouth, described feeding-in and-out mouth is facing to feed hopper.

During work, what enter the charging seat treats that husk rice is by being transported to the ring-type husk rice chamber between iron roll and the screen frame by the outer helicla flute of spiral propeller, under the spiral husk rice groove effect outside iron roll, with the screen frame friction propelling movement of milling, until from the output of feeding-in and-out mouth, enter auger conveyor on the lower shaft by feed hopper afterwards, finishing second road mills, thereby disposable two road husk rice processing, the desirable crudy of acquisition when significantly improving work efficiency, the saving energy and the work-yard of finishing.In rice milling process, can be according to the particle diameter for the treatment of husk rice and moisture content, the regulation and control lift, order about the iron roll move left and right by spiral propeller, because iron roll and screen frame all have tapering, so after relative position changed, its ring-type husk rice gap each other can become big as required or diminish, thereby adapt to the rice processing of different regions, make the husk rice quality that has basically identical after the rice processing of different qualities.

The utility model further improves, and described lift moves horizontally the end face that secondary sliding seat withstands on spiral propeller by constituting with holder, and the husk rice running is reliable and stable.

The utility model further improves, and described upward axle and lower shaft are has the hollow shaft that is communicated with husk rice chamber radial hole by the iron roll slit, and last axle and lower shaft screen frame have the chamber that is communicated with chaff suction tube outward respectively, has good water conservancy diversion row chaff effect.

The specific embodiment

Embodiment one

The full-automatic adjustable double roll rice polisher basic structure of present embodiment is shown in Fig. 1,2, comprise on the level that is supported on the frame 30 axle 12 and lower shaft, horizontally-arranged lift 8, the spiral propeller 4 that circumferentially retrains that 0.75KW motor 27 drives by reductor are installed respectively on last axle 12 and the lower shaft according to the order of sequence, have the iron roll 16 of tapering and are withstood on the back-moving spring of iron roll 16 end faces.Iron roll 16 overcoat harness have the fixedly screen frame 15 of the tapering that matches with it.Be equipped with respectively and frame 30 relatively-stationary charging seat 1 and feed hoppers 22 top of last axle and lower shaft auger conveyor, and be equipped with respectively and frame 30 relatively-stationary upper and lower rice output mouths 21 last axle and lower shaft back-moving spring below, and the feeding-in and-out mouth is facing to feed hopper 22.In addition, the rice mill of present embodiment also has following design feature:

1) lift 8 moves horizontally the end face that secondary sliding seat 6 withstands on spiral propeller 4 by constituting with holder 5, so plays simultaneously axially and radially maintenance effect with back-moving spring during the husk rice running, avoids beating and play, and is reliable and stable.

2) go up axle 12 and lower shaft and be the hollow shaft that has by connection husk rice chamber, iron roll 16 slits radial hole, last axle 12 and lower shaft screen frame have the chamber that is communicated with chaff suction tube 29 outward respectively, therefore can pass through the hollow shaft air intake, again by the chaff suction tube air draft, bran is in time discharged.

Present embodiment is not difficult to understand in conjunction with prior art according to foregoing description by the husk rice operation principle of iron roll screen frame, does not give unnecessary details in addition.Conclusion is got up, and its remarkable advantage has:

Therefore 1. iron roll has certain taper, can regulate the indoor gap length of husk rice, and no matter whether the place of production, grain of rice size, water content be different, all can carry out normal process, obtains high-quality husk rice effect, reduces broken rice rate.

2. two roads roll on a machine once property and finish, so work efficiency significantly improves, and have saved the energy and work-yard.

3. husk rice ability is strong, output is big, and on-the-spot installation and maintenance dismounting are more convenient, appearance looks elegant.
