Abstract

The utility model relates to a multifunctional impurity removing machine for grain. The utility model is characterized in that a conical screen drum is supported and clamped at the middle of the upper part of a frame of the multifunctional impurity removing machine for grain by a liquid wheel, wherein, one end of the screen drum is provided with a belt slot which is driven to rotate by an electric machine, a belt wheel and a rubber tape; a material feeding hopper is fixedly arranged on a frame at the inlet point of the screen drum; a conical material collecting hopper is fixed on a frame below the screen drum; the outlet point of the material collecting hopper is provided with a control valve plate; a blower is fixed at the side face at the lower part of the frame, and a wind chamber is fixed in a frame at the outlet point of the blower; an oblique flat screen is fixed on a frame below the wind chamber, and both sides of the oblique flat screen and the upper side of the oblique flat screen are respectively provided with a sealing plate; the upper end of the oblique flat screen is connected with an impurity collecting box.

Description

Multifunctional impurity removing machine for grain

The utility model belongs to the agricultural machinery class.

Cereal is carried out assorted clearly, what generally use at present is screening machine of flatness and reciprocator, and it is that horizontal screen is formed by framework, motor toggle; Reciprocating motion by horizontal screen makes less foreign material of particle and dust leak down from the sieve end, and bigger foreign material and cereal are discharged from the horizontal screen rear end, and bigger foreign material are searched out by artificial hand.The separate mode of this reciprocating screen is to separate by screening with varying in size of a cereal grain according to foreign material substantially, and this separate mode but can not be separated the foreign material identical with a cereal grain.This separate mode can not cereal identical to a grain, that quality is different carries out classification and grades.The poor-performing that this reciprocating type screening machine is worked continuously, the efficient of removal of impurities is lower.

The purpose of this utility model is: the multi-functional impurity eliminating machine of cereal that provide a kind of and can work continuously, assorted clearly efficient is high, cereal can classification be graded.

The technical solution of the utility model is: stick a taper screen drum middle the propping up by roller of the framework upper of impurity eliminating machine; Screen drum one end has the belt grooves by motor and belt pulley and adhesive tape driving rotation; Be fixed with feed hopper on the framework of screen drum porch; There is a control valve plate in the exit of fixing a taper aggregate bin, aggregate bin on the framework below screen drum; Fix a blower fan in the framework lower side, fix an air compartment in the framework at fan outlet place; Fix an oblique plansifter on the framework below air compartment, tiltedly plansifter both sides and top a shrouding arranged respectively; Tiltedly connecting a waste-collecting box on the plansifter.

Impurity eliminating machine of the present utility model, adopt the screen drum can be earlier with separating in the cereal than bigger material, utilize an oblique plansifter the bigger foreign material of the less proportion of a grain can be separated, utilize the foreign material that blower fan can be less with the less proportion of a grain to separate from oblique plansifter upper end; Utilizing blower fan also can carry out classification to it according to the proportion difference of a cereal grain grades.So having, this impurity eliminating machine separates the good effect thorough, that the efficient of working continuously is high.

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

The framework of this impurity eliminating machine can adopt upper frame 1 and underframe 15 connections form, and can conveniently transport and deposit like this; Also can adopt a general frame.Middle propping up by roller sticks a taper screen drum 6 on the top of framework, and screen drum 6 two ends outer rims have slideway, has the roller that is fixed on the framework, roller to prop up in the slideway outside and is stuck on the slideway, limited the axial of screen drum 6 and moved radially; Screen drum one end has belt grooves, by being fixed on motor on the framework and belt pulley 3 and adhesive tape 4 screen drum 6 is rotated.Be fixed with feed hopper 5 on the framework outside screen drum 6 inlets.Fix a taper aggregate bin 7 on the framework below screen drum 6, a control valve plate 8 is arranged in the exit of aggregate bin 7, valve plate 8 can adopt board plug type, and also can adopt rotating plate type, the effect of valve plate 8 is control what of discharge capacity down.Fix a blower fan 13 in the framework lower side, be fixed with air compartment 12 on the framework in blower fan exit, be fixed with the split-wind plate 11 that distributes air quantity in the outlet of air compartment 12; Be fixed with an oblique plansifter 14 on the framework below air compartment 12, the oblique both sides of plansifter 14 and top a shrouding 10 arranged respectively, shrouding 10 and air compartment 12 and the framework selection by winnowing chamber of solid formation that links.Upper end at oblique plansifter 14 connects a waste-collecting box 16; Locate a hinged adjustable plate 9 in oblique plansifter upper edge, its effect is to regulate wind-force, increases the selection by winnowing effect.In order to increase the selection by winnowing effect, an air quantity plate can be set at the air inlet place of blower fan 13.

The course of work of this impurity eliminating machine is, the cereal that will contain foreign material adds from feed hopper 5, screen drum 6 screenings through rotation, the foreign material of big grain go through the outlet sieve of screen drum 6, the foreign material of cereal and little grain fall through screen drum, outlet through aggregate bin 7 enters the selection by winnowing chamber, and the light foreign material that are clipped in the cereal are blown under the effect of wind-force in the waste-collecting box 16, finally are collected from exporting 17; Be clipped in foreign material heavier in the cereal and sifted out through oblique plansifter 14, cereal tumbles to the lower end through oblique plansifter 14, can carry out classification in a manner described for clean cereal and grade, and need adjust the angle of adjustable plate 9 and the air quantity of blower fan 13 when classification grades.
