Description

Rice milling roller

Technical field

The utility model belongs to paddy processing field of mechanical technique, especially a kind of rice milling roller.

Background technology

Rice milling roller is the key equipment of paddy processing, and at present, the kind of rice mill is a lot, has horizontal rice whitening machine, vertical rice whitening machine, household small-size rice mill.General principle is all similar, all that brown rice enters in husk rice body by feed hopper, under the effect of spiral propeller, enter the husk rice room be made up of rice milling roller, rice huller screen and pressure door vertically, by the impact of outlet pressure door resistance, produce pressure between the grain of rice and the grain of rice, under the effect of rice milling roller and rice huller screen, peeling is rubbed in collision mutually; The high-pressure blast simultaneously spraying the ejection of wind blower fan to be sprayed onto on the grain of rice of milling by the jet-air slot of rice milling roller through inner hole of spindle, namely the rolling strengthening rice is white, take away again part and roll over the heat produced in white process, rice bran is also discharged through rice huller screen with high-pressure blast, the grain of rice of having rolled over flows out from pressure door, thus completes husk rice operation.

The kind of existing rice milling roller is also many, and the quality of different structure to the grain of rice of rice milling roller has a great impact, rice milling roller project organization unreasonable, or the grain of rice is ground or exfoliant effect bad.

Utility model content

Technical problem to be solved in the utility model is to provide a kind of rice milling roller, can improve the walnut hulling rate of brown rice, reduces broken rice rate, improves the crudy of brown rice.

For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of rice milling roller, comprise roll body, the excircle of roll body is provided with the spiral convex rib of more than a section and bar shaped convex tendon more than two along its length, described spiral convex rib and two groups of bar shaped convex tendon intervals are laid, one group of described bar shaped convex tendon is some, and the excircle along roll body is uniform, and the height of described spiral convex rib is identical with the height of bar shaped convex tendon.

Further, described spiral convex rib is 3 sections, and the two ends of roll body are spiral convex rib, and and described two groups of bar shaped convex tendon intervals lay.

Further, the top of described spiral convex rib is arc transition, and spiral convex rib and roll body intersection are provided with fillet.

Further, the two ends of described bar shaped convex tendon are cambered surface transition, and the top of bar shaped convex tendon is cambered surface transition.

Further, between the pitch of described spiral convex rib, be also provided with some auxiliary convex tendons uniform along roll body excircle, assist the height of height lower than spiral convex rib of convex tendon.

Further, the excircle of described roll body is provided with the air nozzle with the channel connection in roll body.

The beneficial effect adopting technique scheme to produce is: the utility model adopts bar shaped convex tendon to coordinate with spiral convex rib, can make fully to collide between brown rice mixing, and owing to adopting cambered surface transition structure, the grain of rice can not be made to pulverize, adopting structure and the reverse acting spiral convex tendon of auxiliary convex tendon, is also ensure the abundant collision between the grain of rice.The utility model can improve the walnut hulling rate of brown rice, reduces broken rice rate, improves the crudy of brown rice.

Detailed description of the invention

Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.

Embodiment one

The utility model is see Fig. 1, comprise roll body 3, spiral convex rib 2 and bar shaped more than two that the excircle of roll body 3 is provided with more than one section are along its length convex, 1, described spiral convex rib 2 and two groups of bar shaped convex tendon 1 intervals are laid, described one group of bar shaped convex tendon 1 is some, and the excircle along roll body 3 is uniform, and the height of described spiral convex rib 2 is identical with the height of bar shaped convex tendon 1.Described spiral convex rib 2 is two sections, and described two groups of bar shaped convex tendon 1 intervals are laid.Wherein, spiral convex rib 2 pairs of grain of rices also play propelling.

Further, the top of described spiral convex rib 2 is arc transition, and spiral convex rib 2 and roll body 3 intersection are provided with fillet.The damage to the grain of rice can be reduced.

Preferably, the two ends of described bar shaped convex tendon 1 are cambered surface transition, and the top of bar shaped convex tendon 1 is cambered surface transition, reduces the injury to the grain of rice.

Wherein, the excircle of described roll body 3 is provided with the air nozzle 4 with the channel connection in roll body 3.

Embodiment two

Embodiment two is with the difference of embodiment one, and see Fig. 2, described spiral convex rib 2 is 3 sections, and the two ends of roll body are spiral convex rib 2, and and described two groups of bar shaped convex tendon 1 intervals lay.Wherein, the spiral convex rib 2 of left end advances the grain of rice just entered, and the spiral convex rib of right-hand member, to the grain of rice one power, makes the grain of rice release and enters discharging opening, discharging.

Embodiment three

The difference of this embodiment and embodiment one is, see Fig. 3, is also provided with some auxiliary convex tendons 5 uniform along roll body 3 excircle between the pitch of described spiral convex rib 2, assists the height of height lower than spiral convex rib 2 of convex tendon 5.Auxiliary convex tendon 5 further makes the grain of rice mixed and disorderly, is beneficial to abundant mixing.

The utility model adopts bar shaped convex tendon 1 to coordinate with spiral convex rib 2, can make fully to collide between brown rice mixing, and owing to adopting cambered surface transition structure, the grain of rice can not be made to pulverize, adopting structure and the reverse acting spiral convex tendon 2 of auxiliary convex tendon 5, is also ensure the abundant collision between the grain of rice.The utility model can improve the walnut hulling rate of brown rice, reduces broken rice rate, improves the crudy of brown rice.
