Abstract

A rice milling machine roller consists of a feeding spiral propeller, a roller body, rice milling toothed bars, rice outlet spiral discharger and the like. The rice milling machine roller is characterized in that on the basis of a common rice milling machine roller, a rice outlet of a roller is additionally equipped with a rice outlet spiral discharger with spiral-structured toothed bars. A rice milling machine utilizing the roller reduces discharge resistance of rice and timely sucks and discharge the rice during a rice milling process, thereby reducing broken rice and increasing production rate. Compared with a rice milling machine without the rice outlet spiral discharger, the rice milling machine utilizing the roller reduces broken rice rate by 50% and increases production rate by more than 80%. The rice milling machine utilizing the roller is simple in structure, light in load, safe and reliable in operation and convenient in repair and maintenance, and is a novel machine which has low energy consumption, high production rate and fine rice quality and is extremely suitable for vast rural areas.

Description

The rice mill roller

Affiliated technical field

The utility model relates to a kind of rice milling roller barrel structure of rice mill.

Background technology

According to present domestic documents and materials and market, the structure of the husk rice roller of existing rice mill generally is that the position that the front charging is carried is the conveying tooth muscle of spiral line type, is line style in upright arrangement and the rear end that extends to rice milling roller at the white gluten of carrying the tooth muscle to engage later.During husk rice, paddy enters into the helical feed tooth muscle of roller front portion from charging aperture, under the effect that roller rotates, helical feed tooth muscle just carries out fragmentation and pearling to the crowded white gluten to the roller rear portion of paddy, discharges from the rear end of roller at last and finishes whole husk rice work.Yet, it all is that forward screw type carries the extruding of tooth rigidity of soft tissues system to move backward that paddy moves axially process from the whole husk rice that is fed to outlet, owing to the resistance that runs into is squeezed greatly, the grain of rice translational speed of advancing is formed slowly piles up, and the phase mutual friction is easily broken and produce and crack rice, cause rice mill to yield poorly, crack rice many, directly have influence on the quality and the use of rice mill.

Summary of the invention

In order to solve the technological deficiency of above-mentioned rice mill, the rice mill roller that the utility model provides a kind of and loaded gently, productivity ratio is high, crack rice few.

The rice mill roller of the utility model design is on the basis of at present general rice mill roller, has increased meter spiral displacer that goes out that the tooth muscle is a spiral-shaped structure behind the milled rice end of roller.Go out meter lead angle β of spiral displacer=12～85 °.Utilize this helical structure rice suction and smooth and easy discharge in time, make the resistance of the whole process rice discharge of rice mill husk rice reduce to minimum, use Mi Sudu and greatly improve, improved productivity ratio, and reduced the generation of cracking rice through pearling.Facts have proved that broken rice rate of the present utility model reduces 50% than the rice mill that does not increase the spiral displacer, its productivity ratio improves more than 80%.

Use the rice mill of such rice mill roller simple in structure, load is light, and is safe and reliable, and maintenance is convenient, is to be suitable for the good type that a kind of energy consumption is low, productivity ratio is high that use in vast rural area.

Among the figure: A. feed auger, B. go out a meter spiral displacer, 01. feed auger tooth muscle, and 02. feed hopper, 03. roller body, 04. husk rice tooth muscle, 05. goes out a meter spiral displacer tooth muscle, 06. rice-supplying slot.

The specific embodiment

Learn that from figure meter bar number of spiral displacer tooth muscle (05) that goes out that goes out meter spiral displacer (B) of the present utility model can be 2,3,4,5 and 6.Bar number with the feed auger tooth muscle (01) of the utility model feed auger (A) is 4 below, and meter bar number of spiral displacer tooth muscle (05) that goes out that goes out meter spiral displacer (B) is that 4 embodiment further specifies:

Among the figure, paddy enters the feed auger (A) at position, rice mill roller front through feed hopper (02), roller body (03) is cast feed auger (A) together with its and is gone out meter spiral displacer (B) rotation under the driving of power, feed auger (A) is undertaken fragmentation and pearling to husk rice tooth muscle (04) position that paddy is advanced to the roller middle part by feed auger tooth muscle (01), rice after pearling enters out a meter spiral displacer (B) at the rear portion of husk rice tooth muscle (04), aspirate out and be transported to rice-supplying slot (06) and finish whole rice milling process by going out a meter spiral displacer tooth muscle (05).

Through facts have proved, to use its broken rice rate of rice mill of the present utility model than not increasing the rice mill that meter spiral displacer (B) and reduce 52%, productivity ratio improves 86%.
