Description

Equal-angular-speed conical hulling Gu Gun

Technical Field

The utility model relates to an equiangular speed conical hulling Gu Gun, which is applied to the field of grain processing, in particular to rice hulling.

Background

In the rice processing process, the rice husking process is called a rice husking process; the existing mainstream technology utilizes two or more pairs of compressed rubber rollers moving in the same direction to provide different rotating speeds for each rubber roller, so that the rubber rollers form a speed difference on the left and right sides of a milling line, and the two sides of the rice passing through the milling line are stressed differently, so that rice hulls are peeled; in the prior art, the rubber rolls are cylindrical, the diameters of each pair of rubber rolls are the same, and in order to realize the speed difference of the rubber rolls on the left side and the right side of a rolling line, the rubber rolls are driven by a complex mechanical structure (such as a gearbox, belt wheel sprockets with different sizes and the like), and are limited by the driving of the mechanical structure, the speed difference between the two rubber rolls cannot be regulated to the optimal speed, so that the shelling rate is limited, the shelling loss is larger, and the use and the regulation are difficult; meanwhile, in order to avoid the rice from bursting to the waist and being damaged due to the large pressure, the rubber roller with proper flexibility is also required to be adopted for manufacturing, and the rubber coated on the rubber roller is a consumable product, so that the rice and byproducts thereof can be polluted, and the production cost is increased to a great extent.

Disclosure of Invention

The utility model aims to overcome the defects in the prior art and provide an equiangular speed conical huller Gu Gun, wherein roller bodies are made into mutually meshed cones, and the section diameters of the roller bodies on two sides of a rolling line are different under the condition of equiangular speed, so that the linear speed difference is naturally generated, and the rice husking is realized; the roller bodies with the same width are inclined to the rolling line by the conical hulling Gu Gun, and are longer than the common straight roller, so that the length of a processing path is effectively increased, and the processing yield is increased.

The utility model is realized by the following modes:

the utility model provides an equiangular velocity conical hulling Gu Gun, which comprises the following components: a driving roller 1 and a driven roller 2; the method is characterized in that: the driving roller 1 and the driven roller 2 are conical, and the driving roller 1 and the driven roller 2 are meshed with each other to form a bevel line type opposite rolling line 3; the driving angular speed of the driving roller 1 is equal to that of the driven roller 2; the conical angle alpha between the driving roller 1 and the driven roller 2 is 30-65 degrees.

Preferably, the conical angle alpha between the driving roller 1 and the driven roller 2 is 5-30 degrees.

Preferably, the conical angle alpha between the driving roller 1 and the driven roller 2 is 65-90 degrees.

Preferably, since the pair of rolling lines 3 in which the driving roller 1 and the driven roller 2 are engaged are beveled lines, when the angular velocities of the two rollers are the same, the right and left sides of each engagement point 31 on the pair of rolling lines 3 except for the intermediate engagement point 4 are different in diameter, and thus the linear velocities are different, and thus the shells passing through the pair of rolling lines rice can be peeled off.

Preferably, since the opposite rolling line 3 of the conical hulling roll Gu Gun is a bevel line, which is longer than a straight line opposite rolling line of a common cylindrical roll, when the roll widths are the same, the conical hulling roll passes through more rice of the opposite rolling line 3 per unit time, the processing amount is larger, and the yield is also larger.

Preferably, the opposite rolling line 3 of the conical hulling machine Gu Gun is a bevel line, on the opposite rolling line 3, the closer to the edge of the roller, the larger the linear speed difference is, the linear speed difference is increased from the middle meshing point 4 to the outer line, and the characteristic is that the passing rice can be automatically classified along with the linear speed difference, the amount of the rice passing through the point with small speed difference is small, and the amount of the rice passing through the point with large speed difference is large; and automatically regulated different granularity rice's motion path, the less corn of granule passes through to the little point of speed difference, and the great corn of granule passes through to the big point of speed difference, produces the characteristic of classifying rice hulling grain, improves rice hulling efficiency.

Preferably, the conical huller Gu Gun adopts the same angular velocity, so that the mechanical driving structure is simple, and the two rollers can be meshed by adopting elastic structures such as springs, gas springs and the like; therefore, the material for manufacturing the conical rice hulling roller does not need to have elasticity, but can be a wear-resistant rigid material; therefore, the use of colloid hulling Gu Gun can be avoided, the use of consumable materials is reduced, and the abrasion of colloid rollers and pollution to rice are avoided.

Preferably, since the linear velocity difference near the middle engagement point 4 of the conical hulling roll is substantially the same or close, the hulling effect is hardly generated, and thus the conical hulling Gu Gun is not fed near the middle engagement point 4.

In summary, the present utility model provides an equiangular velocity conical hulling Gu Gun, which is characterized in that the hulling Gu Gun is made into a conical shape, so that the pair of milling lines 3 formed by each pair of conical hulling rollers are of a bevel line shape, and the natural linear velocity difference of two sides of the pair of milling lines 3 except for the middle meshing point 4 can be realized under the condition of equiangular velocity, so as to realize hulling of rice; the roll body with the same width and the conical hulling Gu Gun effectively prolong the pair of rolling lines 3, so that the treatment capacity is effectively increased.

Description of the embodiments

Specific embodiments of the present utility model will now be described in detail with reference to the accompanying drawings:

as shown in fig. 1 and 2, the present utility model proposes an equiangular velocity conical hulling machine Gu Gun, which comprises: a driving roller 1 and a driven roller 2; the method is characterized in that: the driving roller 1 and the driven roller 2 are conical, and the driving roller 1 and the driven roller 2 are meshed with each other to form a bevel line type opposite rolling line 3; the driving angular speed of the driving roller 1 is equal to that of the driven roller 2; the conical included angle alpha between the driving roller 1 and the driven roller 2 is 30-65 degrees, the linear velocity difference value of the conical roller in the included angle range is moderate, the comprehensive performance is good, and the application range is wide.

Preferably, the conical angle alpha between the driving roller 1 and the driven roller 2 is 5-30 degrees, and the linear velocity difference of the conical roller in the range of the angle is smaller, so that the method is suitable for treating long grain varieties or rice with easy shelling, fragile and explosive waists, and the like.

Preferably, the included angle alpha between the driving roller 1 and the driven roller 2 is 65-90 degrees, the linear velocity difference of the conical roller in the included angle range is large, the shelling capability is strong, and the shelling device is suitable for round grain varieties or raw grains with hard rice quality and uneasy breakage, and can also be used for processing the shelling of some coarse cereals, such as the shelling of coix seeds.

As shown in fig. 2 and 3, since the pair of rolling lines 3 in which the driving roller 1 and the driven roller 2 are engaged with each other are beveled lines, when the angular velocities of the two rollers are the same, the right and left sides of each engagement point 31 on the pair of rolling lines 3 except for the intermediate engagement point 4 are different in diameter, and thus the linear velocities are different, and thus the shells of the pair of rolling lines rice can be peeled off.

Example calculation: assuming that the radius of the drive roll 1 is R for a certain section on the mill line 3 ₁ The radius of the driven roller 2 is R ₂ The angular speeds of the driving roller 1 and the driven roller 2 are omega; the linear velocities on both sides of the engagement point 31 are respectively:

(line speed of drive roll 1) V ₁ =ω×R ₁

(driven roller 2 linear velocity) V ₂ =ω×R ₂

Due to R ₁ ≠R _2， Thus V ₁ ≠V _2， There is a linear velocity difference across the engagement point 31.

The roll width refers to the length of the roll body in the direction parallel to the axis.

As shown in fig. 2, the conical hulling Gu Gun breaks through the idea of a conventional cylindrical roller, and makes the cylindrical roller into a conical roller, and a more severe and difficult roller body making process is accompanied; the components including the matched mounting components need more precise dimensions; meanwhile, as the linear speed difference between the two ends of the conical roller and the linear speed difference between the two ends of the conical roller are different, the determination of the conical included angle alpha needs repeated trial and error, and the expected function of the utility model can be achieved; thus, the present utility model is not readily conceived or pursued by those skilled in the art, and the methods and principles have been developed by the inventors to ultimately summarize.

As shown in fig. 4, since the linear velocity difference near the middle engagement point 4 of the conical hulling roll is substantially the same or close, the hulling effect is hardly generated, and thus the conical hulling Gu Gun is not fed near the middle engagement point 4; the feeding device is designed to be bifurcated left and right.

In summary, the present utility model provides an equiangular velocity conical hulling machine Gu Gun, which is characterized in that hulling Gu Gun is made into a conical shape, so that a pair of rolling lines 3 formed by each pair of hulling rollers are formed into a bevel line shape, and a linear velocity difference can be naturally generated on two sides of the pair of rolling lines 3 except for a middle meshing point 4 under the condition of equiangular velocity, so as to hull rice; the roller body with the same width is effectively prolonged by the conical hulling Gu Gun, so that the treatment capacity is effectively increased; the feeder of the conical huller Gu Gun is designed to be split left and right.
