Description

A kind of rice polishing roller

Technical field

The utility model relates to Cereals Processing Machines field, the polishing roll that particularly in a kind of grain polishing machine, rice surface is carried out burnishing.

Background technology

Widely used polishing rice machine in present China grain processing plant, no matter horizontal or vertical: single roller or two roller, mainly comprise: main shaft 1, roller body 2, polishing room 3, rice huller screen 4, screen frame (unit) 5, support 6 and be positioned at charging aperture 7 and the discharging opening 8 at two ends, polishing room 3 wherein is made of the isometrical annulus that roller body 2 and peripheral rice huller screen 4 parts such as grade form, as shown in Figure 1, its polishing room 3 gap value in the longitudinal direction is all consistent.And the pressure in polishing room 3 is to be formed by grain of rice high velocity impact, friction that the whole material toggling convex body 21 on roller body 2 is stirred in it, therefore the pattern of polishing roll and the structural parameters of material toggling convex body 21 directly affect the movement locus of the grain of rice in polishing room 3, and then are determining the effect of rice polishing and the power consumption of polishing machine.

In domestic all polishing machines, the material toggling convex body 21 of polishing roll is all straight muscle or the diagonal bar of axial integral projection at present, rice polishing roller as disclosed in patent documentation CN202173949U, CN201124098Y, only different on the parameter such as or angle of inclination high at muscle, as shown in Figure 2 and Figure 3, the polishing roll that straight muscle and diagonal bar are combined is also arranged.Material toggling convex body in polishing room 3 is axially continuous to these polishing rolls due to it, thus it stirs the grain of rice diligent be also concentrate together, make the driving of polishing machine need larger power.

In order to reduce the required power of polishing machine, also there is recently producer to attempt replacing continuous material toggling convex body with the spherical material toggling convex body that disperses, as disclosing a kind of rice polishing roller in Chinese patent literature CN101786030A, CN102029204A, it is laid with material toggling convex body 21 by certain way on roller body, material toggling convex body 21 wherein is 1/4 sphere-like, be fixed on roller body 2 with welding manner, be the point-like arranged distribution.The polishing roll of this kind material toggling convex body has played dispersion whitening chamber internal pressure really, strengthen the effect of phase mutual friction between the grain of rice, but because its material toggling face is too round and smooth, the ability of stirring grain of rice displacement also declines to a great extent, and the grain of rice is after colliding with the sphere convex body, therefore produced as shown in Figure 4 manyly perpendicular to sphere and the resistance opposite with the correct flow direction of the grain of rice, although strengthened phase mutual friction between the grain of rice, reduced the effect of polishing machine power consumption and not obvious.

The utility model content

In order to solve the large technical problem of polishing machine power consumption, reduce polishing room's internal pressure, the utility model provides a kind of rice polishing roller.Described technical scheme is as follows:

A kind of rice polishing roller, the roller body that comprises hollow, the periphery of described roller body is provided with a plurality of material toggling convex bodys that are a distribution, on the periphery of described roller body, the back of each material toggling convex body forms a plurality of air nozzles that are connected with the cavity of described roller body, described material toggling convex body is 1/4 spheroid structure, the axis of its major axis and described roller body be arranged in parallel, and the ellipsoid of described material toggling convex body is consistent towards the rotating direction with described roller body.

Described material toggling convex body interlocks along axially being of described roller body and evenly arranges.

Described air nozzle is obround opening, and it is arranged at the rear of each described material toggling convex body, and the major axis of the length direction of described air nozzle and described material toggling convex body be arranged in parallel.

The length of described air nozzle equates with the long axis length of described material toggling convex body, and both ends both flush.

The beneficial effect that the technical scheme that the utility model provides is brought is:

A. the utility model is improved to the spheroid structure by the material toggling convex body with existing sphere structure, because the material after the collision of all and spheroid all will be along moving with the direction of spheroid Surface Vertical, so polished rice has been stirred on the surface of ellipsoid long axis direction, all disperse spin friction along circumferencial direction in polishing room, and the surface of ellipsoid short-axis direction, stir polished rice, and under the acting in conjunction of follow-up supplied materials extruding, all advance along the axial direction collision in polishing room.The material toggling bulge-structure pattern of spheroid structure provided by the utility model, make polishing machine can adapt to less material toggling pressure in polishing room under the driving of smaller power, strengthened simultaneously the mutual burnishing of storeroom, be created in the rice surface polishing under the ultralow pressure duty, reduce greatly that polishing machine power in the traditional grain process equipment is too large, the too many present situation of power consumption.

B. adopt evenly staggered some distribution material toggling convex body, make material polishing room in by the stressed rotation of integral body, be decomposed into the stressed dispersed material of segmentation and rotate, reduced the pressure in the polishing room, strengthened the phase mutual friction between the grain of rice, improved the polishing effect of rice; After the salient point of the material toggling projection of the grain of rice and spheroid structure collides simultaneously, its direction of motion trends towards its correct logistics direction, minimum inverted running resistance only can produce the friction between the grain of rice, and does not hinder the overall flow direction of logistics, has reduced driving force.

C. dispose by the long axis direction back at the material toggling convex body of each spheroid structure the spray wind hole that equates with long axis length, help rolling and row's chaff of the grain of rice in whitening chamber, and the material toggling convex body blocked the grain of rice, it is entered in air nozzle.
