The screening and impurity-removing combined machine for raw grain is characterized in that the screening and impurity-removing combined machine for raw grain combines the functions of five devices-a circular drum primary cleaning screen, a high-speed vibrating screen, a stone removing machine and two elevators which are desired by an original technique together. A sealed box body 17 is formed into a three-point support by a damper 13 and a lifting/lowering rod 12; the upper end of the box body 17 is provided with a feeding tube 1, and the lower end of the box body 17 is provided with cleaned material outlet 14; a conical drum screen 2, a hopper 19, a middle impurity screen 6, a little impurity screen 7 and a stone screen 10 are lined from top to bottom; the lower part of a wind channel 16 is used for feeding, the upper part of the wind channel is used for discharge, and the wind channel is communicated with a guiding port 21; a motor 15 which is used for driving the whole machine to vibrate is positioned at the lower part of the box body 17. The utility model keeps the screening and impurity-removing effects of an original device, but saves cost by 70 percents, reduces energy consumption by 60 percents, shrinks occupation area by 80 percents, and lowers noise greatly. The utility model is simple in installation, convenient in operation, and favorable in maintenance.

Description

Raw grain screening impurity elimination unit mahine

The utility model relates to a kind of raw grain (paddy, wheat) cleaning screening impurity elimination machinery, specifically is a kind of raw grain screening impurity elimination unit mahine.

At present, original technology generally needs 5 equipment to raw grain (paddy, wheat) screening impurity elimination, i.e. respectively 1 of cylinder receiving sieve, high-speed oscillating sieve, stone remover, 2 of elevators and 5 supporting with it motor.Adopt above equipment investment cost big, floor space is big, installs and operates, keeps in repair complexity, and power consumption is big, the noise height.

The purpose of this utility model is to overcome above defective, a kind of original equipment function that integrates is provided, its technological effect is constant, but significantly reduce cost of investment and noise, reduce floor space and power consumption, simplify installation and operational sequence, convenient maintenance, the raw grain screening impurity elimination unit mahine of remarkable in economical benefits.

The purpose of this utility model is achieved in that a kind of raw grain screening impurity elimination unit mahine, it comprises: support, drum sieve, vibratory sieve, remove stone device and motor, be characterized in: this machine with drum sieve, vibratory sieve, go stone device three machines to be combined in one, describedly go the stone device to adopt to remove the stone sieve, to save original 2 elevators.The supported at three point that the elevating lever that the casing of sealing goes stone to sieve gradient by damper and adjusting constitutes is on the support of elastic construction.Feed pipe is located in the circular cone shaft screen on casing top, circular cone shaft screen left side axle head is fastened on casing top by bearing and bearing block, be positioned at the outer belt pulley of casing and be contained on the circular cone shaft screen axle, the big assorted outlet that communicates with circular cone shaft screen mouth is positioned on the casing of circular cone shaft screen mouth below.The hopper of band gradient is positioned at the below of circular cone shaft screen, opposite with the hopper incline direction in assorted sieve be positioned at the below of hopper, with in assorted sieve be arranged in assorted sieve below with the little assorted sieve of incline direction, the dividing plate that little assorted sieve below is provided with a band gradient constitutes little assorted passage.With in assorted sieve lower end, slope communicate in assorted outlet and the little assorted outlet that is communicated with little assorted passage all be located at casing one side and stretch out outside the casing.Lower end, little assorted sieve slope is a material guide port, with in assorted sieve the go stone sieve opposite with little assorted sieve incline direction be positioned at two sieve belows, box plate and go stone to sieve equidirectional inclination.Be divided into the air channel with steel plate in the casing, the air channel that goes out on advancing down is with material guide port and go stone sieve superjacent air space to communicate, and blower fan is located at a side of lower box.Stone outlet hole is positioned at the material guide port below, goes on the casing of top, stone sieve inclined plane, and clean material outlet is located on the anterior casing of stone sieve lower end, inclined-plane.The motor mounting that drives complete machine oscillation is on the position above the clean material outlet in the preceding casing outside.

Material flows into the circular cone shaft screen of rotation from feed pipe, big assorted being left in the sieve discharged from the assorted greatly outlet of side, material sifts out from the cylinder sieve aperture by hopper and makes material along sieving wide even cloth at the removal of impurities vibrating screen surface, high-frequency, low amplitude vibrations sieve nest that vibrating motor produces are reciprocating, make material jumping equably, through in assorted screen out paddy (wheat) the thing fully screening on little assorted sieve after assorted in clean, in assorted, little assorted therefrom assorted separately outlet and little assorted outlet discharge.The oversize material enters on the stone sieve from material guide port.Under the directed reciprocating comprehensive function of uprush and sieve nest, material and shoulder to shoulder stone (being equal to big or small stone) with paddy and wheat on crimped wire woven mess, carry out layering by proportion is different.Wherein light rice husk, dust etc. are siphoned away by the air channel.Contact with compass screen surface below the sandstone that proportion is bigger sinks to, upwards slip a line outside removing stone mouth discharge machine, the less and surperficial comparatively coarse grain grain of proportion is suspended state, keeps falling under self gravitation and compass screen surface directed movement effect, flows out from discharging opening.

Owing to adopt above structure, the function and the one of 5 equipment of the utility model raw grain screening impurity elimination former design of unit mahine collection, accomplish one-machine-multi-function, its technological effect is constant, but cost of manufacture saves 70%, power consumption reduces 60%, floor space dwindles 80%, noise reduces significantly, be a kind of novel raw grain cleaning equipment of efficient low energy, and simplified installation and operational sequence, convenient maintenance, its remarkable in economical benefits is widely used in the supporting of the transformation of middle-size and small-size grain processing plant cleaning equipment and complete set of equipments.
