Abstract

The utility model provides a vibrating screen for grain and rapeseed with crushing clod and removing dust functions, chiefly comprising a machine frame, a feed funnel, an electric motor, an air blower, a driving belt, a screen cloth body and a crushing mud machine, which is characterized in that a drum air box is arranged on the upper part of the machine frame which can blow off the weeds and dust in the grain and the rapeseed; coarse and fine stuff vibrating screen case bodies between which the crushing mud machine is provided are respectively installed on the middle and the lower part of the machine frame. The electric motor, which is installed at the bottom of the machine frame, drives the air blower and the crushing mud machine rotate by the belt to blow away the weeds and to crush the clods and the pebbles, and meanwhile drives the bent axle and the swivel rotate installed on the machine frame. The bent axle drives the coarse and fine stuff vibrating screen do back and forth movement by the connecting rod to screen the mud and dust in the grain and the rapeseed, and makes the mud and dust move from the higher end to the lower end and export from the outlet. The vibrating screen has the function of wind blowing, grinding and sieving, and it is suitable for the farmers to harvest grain, rapeseed and other seeds.

Description

A kind of hack removal of impurities vibratory sieve that is used for grain, rapeseed

[technical field]

The utility model relates to a kind of farm implements, is a kind of hack removal of impurities vibratory sieve that cleans grain, rapeseed or seed specifically.

[background technology]

As everyone knows, after the peasant gathers in the crops grain or seed, dried before this, and used " windmill " and " screen cloth " that the weeds in grain, rapeseed or the seed, soil block, stone, dust etc. are removed besides, last just that pneumatic jig is clean grain, rapeseed or seed are sold or the storage of putting in storage.Pneumatic jig grain, rapeseed or seed were to carry out respectively with different equipment in the past, blew weeds, dust off with windmill before this, fell soil block, stone with mesh screen again, and device therefor is many, and operation is many, wastes time and energy, and the more important thing is and can not ensure the quality of products; Area that has and peasant in order to save trouble or to be subjected to the restriction of condition, are often saved windmill or screen cloth, just raise with hand to allow natural wind blow some weeds and dust off, and the purity of grain, rapeseed is had a greatly reduced quality, and have a strong impact on the quality of grain, rapeseed or seed.

[summary of the invention]

To carry out respectively with distinct device in order to overcome existing wind, sieve grain, rapeseed or seed, cause equipment needed thereby many, operation is many, the defective that wastes time and energy, the utility model provides a kind of collection wind, and soil crushing, stone, dedusting are stored up grain in the hack removal of impurities vibratory sieve of one to make things convenient for the peasant, sell rapeseed, guarantee that the purity and the quality of article meets GB.

The utility model is that the technical scheme that its technical problem of solution is adopted is: the cavity of or triangle body horn-like one of the upper design of frame, cavity is provided with an air blast near an end of feed hopper outlet, the other end of cavity is provided with the outlet that blows out weeds and dust, top in frame is provided with feed hopper, the feed hopper bottom has a through hole, this through hole communicates with the cavity that triangle body is equipped with air blast one end, so that the material via through holes of feed hopper is dropped in the triangle body cavity, allow air blast blow away wherein weeds and dust.Be provided with the coarse fodder vibratory sieve at the middle part of frame, the bottom of frame is provided with the fines vibratory sieve, these two vibratory sieves connect by four forks and movable being suspended on the crossbeam of frame, slightly, the fines vibratory sieve is the box body that the middle level is equipped with screen cloth, one end of coarse fodder sieve box body is connected with the bent axle that is located at frame one side by connecting rod, when motor makes crankshaft rotating by belt, bent axle makes thick vibratory sieve and drives the fines vibratory sieve reciprocating by connecting rod, the other end of coarse fodder sieve nest is provided with soil block stone discharge opening and foodstuff seed discharge opening, and wherein soil block stone discharge opening stretches in the soil block stone outlet that is located at frame weeds dust export bottom; The below of foodstuff seed discharge opening is provided with mud smash machine, and mud smash machine is a machine that resembles electronic mill, after the soil block bigger than volume of material, stone are fallen into mud smash machine, will be pulverized, and discharges from the outlet of mud smash machine bottom then; Be provided with fines vibratory sieve box body in the bottom of mud smash machine, one end of this box body is located under the mud smash machine outlet, the screen cloth of the other end is provided with the material discharge opening, and the box plate under the screen cloth is provided with earth, fine sand dust discharge opening, and corresponding site is provided with discharging opening under each discharge opening.

During work, motor is by the rotation of belt drives air blast, simultaneously by belt drives bent axle and mud smash machine rotation, it is reciprocating that crankshaft rotating drives the coarse fodder vibratory sieve, grain in the feed hopper, rapeseed or other seeds drop after wind blows away the weeds dust into the coarse fodder vibratory sieve, soil block, outside the portalling discharge body of stone on screen cloth, grain, rapeseed or seed drop on bottom screening plate through sieve aperture, drop into pulverizer through portalling, soil block wherein, stone is after pulverizing, clean grain, rapeseed or seed outside discharging opening is discharged body, earth, dust is discharged outside the body through the outlet of bottom screening plate one end.

The beneficial effects of the utility model are: 1. the utility model integrates wind, sieves, rolls, and a tractor serves several purposes is time saving and energy saving, can make things convenient for the peasant to gather in the crops grain, rapeseed or seed; 2. grain, rapeseed or the seed of the utility model processing do not have weeds, silt particle, dust, can guarantee the purity and the quality of grain, rapeseed or seed, improve the grade of grain, rapeseed or seed.3. the utility model is simple in structure, makes easily, and cost is low, and is easy to utilize.
