Abstract

The invention relates to a paddy pounder with a rice sieve provided with multiple arrayed ventilating slots. The paddy pounder is characterized in that the arris of a rice sieve sheet folded into a regular polygon cylinder are provided with the ventilating slots which are perpendicular and symmetrical to bending lines and are arrayed according to a certain spacing, the material inlet of the rice sieve sheet is provided with protrusions and ventilating slots which form an included angle alpha with a shaft axis of the rice sieve and are arrayed according to a certain spacing, and the material outlet of the rice sieve sheet is also provided with protrusions and ventilating slots which form an included angle beta with a shaft axis of the rice sieve and are arrayed according to a certain spacing; only the ventilating slots but not the protrusions are arranged within a certain length of the outlet end of the rice sieve sheet, a baffle is fixed to the material outlet of the rice sieve sheet approximating to the middle of the rice sieve through a sunk screw, a flat washer, a spring washer and a nut, and one side of the arris bending line is provided with baffle plates spaced by the arris at intervals. By adopting the ventilating slots which form multiple included angles with the shaft axis of the rice sieve on the rice sieve, the invention enlarges the ventilating area of the whole rice sieve, is beneficial to the discharge of rice bran, changes the surface shape of the rice sieve, and enhances the quality, the output and the efficiency of a rice sheller.

Description

The rice mill of sieve having ventilation slots in various arrangements

Technical field

The present invention relates to the paddy processing equipment, especially the rice mill of sieve having ventilation slots in various arrangements.

Background technology

Rice mill is the key equipment of paddy process equipment, in complete set of rice milling equipment, brown rice is ground into rice, and at present the maximum of usefulness are the iron roll jet-air rice polishers.Brown rice is got in the husk rice body by hopper; Under the effect of spiral propeller, get into the husk rice chamber that rice milling roller, rice huller screen and pressure door are formed vertically; Receive the influence of outlet pressure door resistance, make between the brown rice grain and produce pressure, under the effect of rice milling roller muscle and rice huller screen surface configuration, grind each other and wipe peeling.Simultaneously; The high-pressure blast of spray wind blower fan ejection is sprayed onto by the jet-air slot of rice milling roller through the main shaft endoporus and grinds the grain of rice of wiping peeling, has both strengthened the pearling of rice, has taken away the heat that part produces in the pearling process again; Rice bran is discharged through rice huller screen with high-pressure blast, grinds good rice and flows out from pressure door.The quality of husk rice and output comprise degree of crushing (broken rice rate), the energy consumption (ton-grain power consumption) of rice, regulate relevant with the rice huller screen structure with the pressure of pressure door.The draught capacity of rice huller screen and surface configuration are bigger to the quality of husk rice and output and effectiveness affects; The rice huller screen of present iron roll jet-air rice polisher is generally just many prismatics tube; What have is contained in just many prismatics tube of rice sieve support with multi-disc sieve sheet; The two rice huller screen sheets with foldable type that also have are installed in respectively on two half-open rice sieve supports, are assembled into whole rice sieve support again.The ventilation slot of existing rice huller screen is consistent with the angle of rice huller screen axial line.

Summary of the invention

The rice mill that the purpose of this invention is to provide a kind of sieve having ventilation slots in various arrangements, it adopts the rice huller screen that multiple arrangement ventilation slot is arranged.Increase the draught capacity of husk rice chamber, improved the surface property of rice huller screen sheet.

The objective of the invention is to realize as follows: two measure-alike rice huller screen sheets are separately fixed at pressing plate and then are combined into just many ribs tubular rice huller screen on the rice sieve support of splitting.The rice huller screen sheet is by the sheet metal bending and molding, the rice huller screen sheet just be converted into the rib place of many ribs tube have vertical with bending line and symmetrical, the ventilation slot of arranging by a determining deviation; The material inlet of rice huller screen sheet partly have with rice huller screen axial line angle be α, the ventilation slot and the convexity of arranging by a determining deviation; The material outlet of rice huller screen sheet partly have with rice huller screen axial line angle be β; Ventilation slot and convexity by determining deviation arrangement; In the certain-length of the material outlet end of rice huller screen sheet, have only ventilation slot not have convexity; The material outlet part that baffle plate is fixed on the rice huller screen sheet with sunk screw, plain washer, spring washer and nut is near the rice huller screen medium position, and a side of rib bending line has a baffle plate at a distance from a rib.

Ventilation slot and rice huller screen axial line angle are α=69 degree～71 degree, β=19 degree～21 degree.

Rice huller screen sheet surface heat is handled HV >=1700.

The advantage of the rice mill of this sieve having ventilation slots in various arrangements is: because rice huller screen adopts and the ventilation slot of its multiple angle of axial line; Increased the draught area of whole rice huller screen; Help the discharge of rice bran, changed the shape on rice huller screen surface, improved quality and the output and the efficient of husk rice.

The specific embodiment

In accompanying drawing 1; The hole of rice huller screen sheet (1) through its both sides is contained on the rice sieve support of splitting (4) with pressing plate (6) and a plurality of sunk screw second (5) and corresponding plain washer, spring washer and nut; A plurality of bolts (7) and corresponding spring washer thereof are assembled together 2 identical rice sieve supports (4) with nut, and the combination back is the positive 12 rib tubular rice huller screens of the rice mill of sieve having ventilation slots in various arrangements.Rice huller screen sheet (1) is by 2 millimeters sheet metal bending and moldings.

Accompanying drawing 2 is views that rice huller screen sheet (1) launches, and before rice huller screen sheet (1) moulding, on sheet metal, goes out the ventilation slot (9) and protruding (10) of elongated strip shaped, and the ventilation slot (9) of general rice mill rice huller screen all is 69 degree～71 degree with the angle of rice huller screen axial line.Newly-designed rice mill rice huller screen has the ventilation slot of arranging by 3 kinds of angles with the rice huller screen axial line (9).1, rice huller screen sheet (1) just be converted into the rib place of many ribs tube have vertical and symmetrical with bending line (8), by the ventilation slot (9) that a determining deviation is arranged, bending line (8) and rice huller screen axis parallel, just ventilation slot (9) is 90 degree with the angle of rice huller screen axial line.This is that common rice huller screen does not have, and it has thoroughly changed the ventilation condition at rice huller screen rib place, has increased the draught capacity of whole rice huller screen.2, the material inlet of rice huller screen sheet (1) part also is the first half of rice huller screen, have with rice huller screen axial line angle be (α)=69 degree～71 degree, by ventilation slot (9) and convexity (10) that a determining deviation is arranged, this is identical with common rice huller screen.3, the material outlet of rice huller screen sheet (1) part also is the latter half of rice huller screen; Have with rice huller screen axial line angle be (β)=19 degree～21 degree; The ventilation slot (9) and convexity (10) arranged by a determining deviation have only ventilation slot (9) that convexity (10) is not arranged in 1/7 rice huller screen sheet (1) length of the material outlet end of rice huller screen sheet (1).The material outlet part that baffle plate (2) is fixed on rice huller screen sheet (1) with sunk screw (3) and corresponding plain washer, spring washer and nut is near the rice huller screen medium position, and a side of rib bending line (8) has a baffle plate at a distance from a rib, and effect is rolling of the quickening grain of rice.

The arrangement and the shape of ventilation slot (9) and protruding (10) are seen accompanying
