Abstract

The invention relates to a cereal screening and dust raising all-in-one machine. The cereal screening and dust raising all-in-one machine comprises a rack, a spring mechanism, a screening box, a vibration motor, a discharging device and a winnowing device. The machine is simple in structure and convenient to use, only one vibration motor is applied, the energy consumption of work is low, and the high practicability is achieved. Through application of two layers of screens, large impurities and micro impurities can be cleaned away at the same time at a time, impurities and dust of materials which are cleaned are cleaned away again through the winnowing device, and the content of the impurities in the materials is greatly reduced. Application of the discharging device enables the impurities and the materials to be completely separated, and meanwhile the impurities are effectively recycled. Compared with a traditional device, the machine greatly reduces dust pollution of the environment and labor intensity, and improves the work economical efficiency.

Description

A kind of grain screening airborne dust all-in-one

Technical field

The invention belongs to grain-production process equipment field, be specifically related to a kind of grain screening airborne dust all-in-one.

Background technology

Grain screening due to screening and the main object of gravity separation be cereal, with regard to its character, bulk solid is called as between solid and liquid, bulk solid has mobility and automatic classification performance, health powder content in grain screening device inspection grains, the percentage of impurity of oil plant sample and cereal, determines a kind of testing instruments of its quality grade.

The principle of grain screening: be separated according to material width, thickness or shape difference: be 1. separated by grain thickness difference: rectangle sieve aperture is separated according to material thickness difference.2. be separated by grain width difference: round sieve mainly carries out being separated according to material width difference.3. the shape difference of pressing grain is separated: triangle sieve aperture is mainly separated according to the shape of material.

On market, cereal screening washer is all generally the equipment that automaticity is higher, and cost is high on the one hand, and on the other hand, can utilize the sands are running out in 1 year, effective rate of utilization is low.

Summary of the invention

The invention provides a kind of grain screening airborne dust all-in-one, can effectively solve the problem.

The present invention is achieved through the following technical solutions:

A kind of grain screening airborne dust all-in-one, comprise frame, spring mechanism, screen box, vibrating motor, discharger and pneumatic separation device, described screen box is arranged on frame upper surface, and screen box is overall parallel with frame upper surface, multiple spring mechanism is equiped with between screen box and support, described frame is for tilting forward and back, frame at the height of conveying end higher than the height of output, the upper end of described screen box is equiped with feeding groove, the middle of screen box is equiped with vibrating motor, screen box box house is equiped with two layer screen network selection, foreign material outlet is offered in side, screen box lower end, described discharger is connected with screen box lower end, and inside communicates, the upper end of discharger is connected with pneumatic separation device, and pneumatic separation device and material are discharged layer and are connected and communicate.

Further, the bottom of described frame is equiped with four rolling.

Further, in described screen box, upper strata screen cloth and the space between lower screen and the material of discharger are discharged layer and are connected and communicate, the lower end spaces of described lower screen and the chip of discharger are discharged layer and are connected and communicate, and the upper end space of upper strata screen cloth is connected with foreign material outlet and communicates.

Further, the angle of inclination in described pedestal upper end face is 30 °.

Further, described vibrating motor is fixedly mounted on screen box by crossbeam.

Further, described discharger outlet is also provided with hook.

Cereal enters screen box from feeding groove, upper and lower two-layer screen cloth is had in screen box, upper strata screen cloth mesh is larger, lower screen mesh is less, lower screen mesh is less than the cereal of screening, ensure that cereal is not by lower screen, when cereal falls into screen box, under the effect of vibrating motor, cereal moves along the incline direction of screen box, cereal is made to drop down onto on lower screen by upper strata screen cloth because upper strata screen cloth mesh is greater than cereal, larger impurity is selected by upper strata screen cloth, discharge finally by foreign material outlet, cereal filters out tiny particulate and dust by lower screen network selection, cereal is discharged layer by discharger from material and is discharged, by pneumatic separation device removal of contamination and dust further while discharging, discharge layer by the chip impurity of lower screen by the chip of discharger to discharge.

Beneficial effect of the present invention: structure of the present invention is simple, easy to use, an only application vibrating motor, operating power consumption is low, there is stronger practicality, by the application of two-layer screen cloth, can once by comparatively bigger material and micro-impurities are removed simultaneously, the material removed is through pneumatic separation device removal of contamination and dust again, greatly reduce the content of impurity in material, impurity can be separated with material by the application of discharger completely, effectively reclaim impurity simultaneously, to compare traditional equipment, this equipment greatly reduces the dust pollution of environment, reduce labour intensity and the economy that improve operation.
