Abstract

The utility model discloses a grain cleaning machine, which comprises a frame body, wherein the lower end of the frame body is provided with a steering wheel and a traveling wheel; oblique screen drums are rotatablely arranged in the frame body; a screen drum motor is in transmission connection on the outer side of each screen drum; a vibrating screen is arranged below the screen drums; a vibrating motor is fixedly arranged on the vibrating screen; the lower end of the vibrating screen is communicated with a dust collection air duct; the lower end of the dust collection air duct is provided with a grain outlet; the other end of the dust collection air duct is connected with a cyclone dust collector; the lower end of the cyclone dust collector is provided with a light impurity auger; the upper end of the screen drum is communicated with a feed hopper; a large impurity outlet is formed below the screen drum respectively; and the lower end of the vibrating screen is provided with a small impurity outlet.Since two single-layer screen drum bodies are combined for use, the filtering area and the processing capacity are greatly increased, and large impurities in grain are removed.The vibrating screen on the lower layer is used for performing secondary cleaning to remove small impurities and dust in the grain. Light impurities and dust in the grain, which is subjected to secondary cleaning, are removed at the outlet through the cyclone dust collector.

Description

The grain descaling machine

Technical field

The utility model technology relates generally to grain cleaning mechanical field, is that drum sieve, vibratory sieve, cyclone dust collectors comprehensively are the concentrated cleaning center of one.

Background technology

China's grain need carry out removal of impurities dedusting operation when purchase stores at present.In the face of the successive increasing both production and income of grain in recent years, storage department also must improve and stores up efficient, with quick qualified the putting in storage of assurance grain, provides safeguard for guaranteeing grain security.And existing cleaning equipment exists treating capacity little, and shortcomings such as cleaning effect difference do not satisfy the grain storage requirement of putting in storage.Must have and a kind ofly can remove big small impurities, dust and light assorted, the cleaning machinery that can raise the efficiency is again finished the prune job that puts in storage of present stage.Satisfying above-mentioned requirements, is current urgent problem.

The utility model content

The utility model provides a kind of grain descaling machine, is the synthesis of having gathered cylinder sieve nest, vibratory sieve and Asta-3746 cyclone dust collectors group.Cereal is carried out the cleaning of multiple fractionation science, reach the national standard limit value of grain storage.Being used in combination of two individual layer screen cloth cylinders increased filter area and treating capacity greatly, removes big the mixing in the cereal.Lower floor's vibration sieve nest carries out the secondary cleaning to cereal, removes the little assorted and dust in the cereal.The cereal that secondary was cleared up is removed wherein light assorted and dust in the exit through the cyclone dust collectors group.

The utility model technical solution is in order to achieve the above object:

The grain descaling machine, include Rack Body, the Rack Body lower end is equipped with deflecting roller, road wheel, rotate the screen drum that is provided with inclination in the Rack Body, the screen drum screen drum motor that has been in transmission connection outward, the screen drum below is provided with vibratory sieve, be installed with vibrating motor on the vibratory sieve, the lower end of vibratory sieve is connected dust absorbing air passage, and the lower end of dust absorbing air passage is the mouth of putting out cereal, and the dust absorbing air passage other end connects cyclone dust collectors, the lower end of cyclone dust collectors is provided with light assorted auger, screen drum upper end is connected to be had feed hopper, the below of screen drum to connect respectively to be equipped with big assorted outlet, and the lower end of vibratory sieve has little assorted outlet.

In the described dust absorbing air passage induced-draught electric motor is installed.

The clear grain of the utility model technology center is made up of cylinder sieve nest, vibratory sieve and Asta-3746 cyclone dust collectors.Two cylinder sieve nests are placed side by side in the housing of being made up of support body and upper top cover, and the cylinder sieve nest tilts to place, and drive part is at the low side of screen drum, and material is sent in the screen drum respectively from high-end hopper.Tilted-putted shaker screen surface vibration sieve is installed under the cylinder sieve nest, clears up once more through vibratory sieve by the cereal that flows out in the screen drum.Cereal is removed wherein light assorted and dust through vibratory sieve low side exit by uniform negative-pressure air-flow, has reached the purpose of orderly cleaning.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is a vertical view of the present utility model.

Number in the figure is: dust absorption fan 1, dust absorbing air passage 2, cyclone dust collectors 3, gently assorted auger 4, deflecting roller 5, the mouth 6 of putting out cereal, little assorted outlet 7, screen drum motor 8, vibratory sieve 9, screen drum 10, vibrating motor 11, Rack Body 12, road wheel 13, feed hopper 14, big assorted outlet 15.

The specific embodiment

Referring to accompanying drawing, the grain descaling machine, include Rack Body 12, Rack Body 12 lower ends are equipped with deflecting roller 5, road wheel 13, rotate the screen drum 10 that is provided with inclination in the Rack Body 12, the screen drum 10 outer screen drum motors that have been in transmission connection, screen drum 10 belows are provided with vibratory sieve 9, be installed with vibrating motor 11 on the vibratory sieve 9, the lower end of vibratory sieve 9 is connected dust absorbing air passage 2, the lower end of dust absorbing air passage 2 connects cyclone dust collectors 3 for the mouth 6 of putting out cereal, dust absorbing air passage 2 other ends, and the lower end of cyclone dust collectors 3 is provided with light assorted auger 4, screen drum 10 upper ends are connected feed hopper 14, the below of screen drum 10 connects respectively and is equipped with big assorted outlet 15, and the lower end of vibratory sieve 9 has little assorted outlet 7, and induced-draught electric motor 1 is installed in the dust absorbing air passage 2.

Power path:

Cyclone dust collectors: blower motor → dust absorption fan 1

Drum sieve: screen drum motor 8 → chain → screen drum 10

Vibratory sieve: vibrating motor 11 → vibratory sieve 9

Operation principle:

Cereal is from feed hopper, and warp is the sub-material mouth evenly, enters two drum sieve height ends respectively, and the cylinder sieve nest is a wide-meshed screen, and cereal is under the effect of angle of crater, Yi Bian pass screen cloth, Yi Bian trickle to low side, the big outlet 15 of mixing of the big assorted warp that sifts out is discharged.The cereal that drops on the vibratory sieve passes through vibratory cleaning once more, and to outlet, discharge through little assorted outlet 7 by screenings such as little assorted particle from the dusting cover surface current for cereal.The flow through cereal in vibratory sieve exit is cleared up wherein light miscellaneous material once more by cyclone dust collectors, light assortedly discharge through light assorted auger 4, and clean grain mouthfuls 6 is discharged by putting out cereal.
