Description

Vertical stone roller is cut rice mill

The utility model relates to a kind of roller and even part thereof of utilizing the vertical stone roller that brown rice cortex stone roller goes is cut rice mill.

Existing vertical rice whitening machine, cut rice mill as Chinese patent 932353703 disclosed vertical jet-air rice polishers, Chinese patent 942308689 disclosed vertical double roll rice polishers, Chinese patent 950258448 disclosed vertical rice whitening machines, Chinese patent 952373955 disclosed vertical stone rollers, though have advantages such as broken rice rate is lower, but still there is following deficiency: the one, whitening chamber rice cutter negligible amounts (being generally 2), rice cutter overall width is less, the grain of rice is wiped relatively poor from the effect of pearling, grain of rice tumbling motion degree a little less than, rough white irregular phenomenon is more obvious; The 2nd, compare with the utility model, under the condition of same product throughput rate, its whitening chamber primary structure (as roller diameter and length) is huge, complete machine production cost height.

The purpose of this utility model is to overcome the deficiency of existing vertical rice whitening machine at above-mentioned technical elements, provides new principle and structure at whitening chamber, feed arrangement, discharge mechanism and row's chaff device of rice mill, to improve the processing performance of rice mill.

Realize that the utility model purpose technical scheme is: form by base, lower shell and bearing block, middle cylinder body, whitening chamber, feed arrangement, discharge mechanism, motor and machine driven system and suction chaff device etc.On lower shell, lower shell and motor cloth are placed on the base top surface by the main shaft supporting of motor through being with transmission, and middle cylinder body cloth is placed on lower shell and bearing block upper end, and multi-head spiral is wherein built-in; The whitening chamber cloth of being made up of vertical hollow spindle, roller, stone roller sharpener, polygonal screen frame, trapezoidal rice huller screen, bar shaped rice cutter and waveform rice poking wheel etc. is placed on the middle cylinder body upper end; By hopper, flashboard and operating mechanism (this mechanism again by handle knob, nut, screw rod, back-up ring, screw bolt seat and pin form) the feed arrangement cloth formed is placed on the intermediate cylinder body side surface; The discharge mechanism cloth of being made up of cylindrical shell and discharging mouth, visor, top board, pressure door, balanced weight, transverse axis, chuck, lever, counterweight etc. is placed on the whitening chamber upper end; Row's chaff device that machine internal channel, machine Outer Tube and the blower fan (not shown) that the annular space of the annular space that is formed by rice huller screen and outer cover, the annular space in the middle cylinder body and lower shell is formed formed, its machine internal channel outlet is arranged on the sidewall of lower shell bottom.

During work, starter motor, through the band transmission, main shaft and roller run up, operation knob and screw rod, and clockwise rotate around pin, nut and flashboard are thrown off, flashboard is opened, when treating that gatage is suitable, adjusting screw(rod) combines nut again with flashboard, material in the hopper enters in the multi-head spiral of middle cylindrical shell, send effect to enter whitening chamber down at " pump " of spiral, the stone roller sharpener sword wedging grain of rice cortex of high-speed motion is cut the rice stone roller that moves, the grain of rice of acquisition speed and pressure collides mutually, produce impulsive force and frictional force, make the cortex fracture and peel off, the grain of rice after this and bull rice cutter and multiaspect rice huller screen collide, further make cortex wipe from, under the suction function of row's chaff device, discharge rice huller screen.Grain of rice fluid is in whitening chamber motion process from lower to upper, and the grain of rice, backs down pressure door under the promotion fast at rice poking wheel at last and flows out from the discharging mouth with tumbling motion and by pearling through for several times collision.

The utlity model has following advantage:

1, it is strong to grind the ability of cutting, and processing performance is good.Because the roller of whitening chamber is made of roll body and the power of cutting of grinding more, the periphery of whitening chamber is made up of many rice cuttves and multi-disc rice huller screen, quickens the collision effect and the tumbling motion of the grain of rice like this, significantly strengthens the pearling effect of the grain of rice.

2, productivity ratio height.Owing to adopted benefit wind mode in the feed arrangement, made the automatic feed of material fluidised form; Owing to adopt multi-head spiral, and principle is sent in " pump " suction that makes itself and lining constitute the fluid conveying; Since the arc pressure door aperture spaciousness of discharge mechanism, mechanism's sensitivity; Because the whitening chamber axial length is short, the area of passage on the cross section is big; Again because the fluid effect of row's chaff device negative pressure, the utility model with compare the big 20-40% of its production capacity with the rice mill of the same structural dimensions of power (roller diameter).

Below in conjunction with accompanying drawing example of the present utility model is described further.
