Abstract

The utility model relates to a sieve, in particular to a movable cleaning sieve for grain and oil raw material, which is designed aiming at the technical problem that the commonly used cleaning sieves are mostly complicated in structure easy in error and inconvenient in maintenance and do not have ideal dust removing effect and so on. The utility model has the technical proposal that one side at the upward side of a machine rack[2] is provided with a feed hopper[1]; a wind absorption machine[11] corresponding to the feed hopper is arranged on the machine rack[2]; the machine rack[2] at the downward side of the feed hopper[1] is hinged with a sieve body[4] through a double-rocking rod mechanism[3]; the downward side of the sieve body[4] is connected with a brace rocking rod mechanism; the wind absorption machine[11] and the brace rocking rod mechanism are connected with a power device[12] through transmission belts. The utility model adopts wind absorption selecting and double-layer sieving manners, and utilizes the wind absorption machine to absorb the dust and utilizes a cyclone dust collector to collect dust and land, which has good food cleaning effect and low power consumption and improves the sanitation environment of labor work. The utility model is simple and compact in structure, low in error rate, convenient in use and maintenance, convenient in move and low in cost so as to be convenient for being popularized and used in vast food purchasing station points and countries.

Description

The portable cleaning sieve of grain and oil raw material

Technical field

The utility model relates to a kind of sieve, and particularly a kind of movable type cleaning that is used for grain and oil cereal is cleared up is sieved.

Technical background

The cleaning sieve that has had at present multiple structure and kind as screening type, winnowing type or the like, is used it for shrivelled kernel shell, straw rope, dust, the sand of cleaning particle grain and oil crop.But it is comparatively complicated that structure is sieved mostly in these cleanings, easy break-down, it is convenient that maintenance is also owed, the dedusting impurity-eliminating effect is also desirable not to the utmost, and to around environment certain pollution is arranged.

Summary of the invention

The purpose of this utility model is to provide a kind of safe, low in energy consumption effective grain and oil raw material simple and compact for structure, simple to operate portable cleaning sieve.The purpose of this utility model is achieved through the following technical solutions: a side is equipped with hopper 1 above frame 2, the exit of 2 relative hoppers 1 is installed on induced-draught fan 11 on frame, on the frame below the hopper 1, be hinged with sieve nest 4 by double-lever mechanism 3, the below of sieve nest 4 links to each other with crank and rocker mechanism, and induced-draught fan 11 and crank and rocker mechanism join by driving belt and power set 12.

In order to clear up big impurity, can clear up small impurities again, sieve nest adopts double-deck sieve nest, and the upper strata is for removing big impurity crude mesh sieve body 4, and lower floor is that all the side neck to the mouth of putting out cereal is oblique for detailed catalogue sieve nest 5, two sieve nests.Lower end at clean grain detailed catalogue sieve nest 5 sets out grain mouth 15, is holding the impurity mouth 16 that is provided with to lopsidedness except that having a down dip of big impurity crude dusting cover body 14.

Regulate the air draught air quantity of induced-draught fan for convenience, but the air intake place of induced-draught fan 11 is provided with air register.

For fear of dust polluting environment, the Asta-3746 17 that joins with induced-draught fan 11 is installed in a side of frame 2.

For conveniently moving, roller 9 is installed below frame 2.

As shown from the above technical solution, the utility model is to adopt air draught selection by winnowing and double-deck screening mode, utilizes blower fan dust suction, the landing of Asta-3746 control of dust, and clear grain is effective, low in energy consumption, and improves the labour health environment.It is simple and compact for structure, and fault rate is low, easy to use and maintenance, and conveniently moving, cost is low, thereby is convenient to vast grain purchases website and rural area and promotes the use of.

Description of drawings

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

The specific embodiment

By Fig. 1 to Fig. 2 as can be known, frame 2 of the present utility model is a frame shape, a side is equipped with hopper 1 above frame 2, exit, lower end at hopper is equipped with hopper switch 10, can be used to regulate the flow that raw material enters, exit corresponding to hopper on frame 2 is equipped with induced-draught fan 11, but the inlet scoop that is provided with the induced-draught fan of air register faces toward the outlet below of hopper, but regulate air quantity by air register and control fan delivery, the isoparametric variation of blast, to reach the grain of cleaning different cultivars, a side of induced-draught fan 11 is equipped with the belt pulley 14 that links with blade shaft, links by belt 13 and motor 12.Below hopper and blower fan, be hinged by double-lever mechanism 3 and double-deck sieve nest up and down, it can clear up big impurity, can clear up small impurities again, it is at the middle and upper levels for removing big impurity crude mesh sieve body 4, lower floor is clean grain detailed catalogue sieve nest 5, sieve nest connects firmly mutually up and down, and all longitudinally tilt to the grain mouth, and the angle of inclination of the clean grain micro mesh sieve of lower floor and entire length are greater than the gradient and the entire length of removing big impurity crude mesh sieve body on upper strata, the end that has a down dip of clean grain detailed catalogue sieve nest is the mouth 15 of putting out cereal, in addition, also be provided with at the end that has a down dip that removes big impurity crude mesh sieve body 4 and go out impurity mouth 16 to lopsidedness, a side is equipped with by crank axle 7 and rocking bar 6 and the crank and rocker mechanism formed with the belt pulley 8 that crank axle links below sieve nest, crank and rocker mechanism is hinged by rocking bar 6 and sieve nest, belt pulley 8 links by belt 18 and motor 12, for ease of moving, also is equipped with roller 9 below frame 2.

The utility model also purifies by utilizing Asta-3746 17 to carry out essence, so that remove dusts very tiny as below 10 microns, it can make the residue dustiness in the cleaned air passes reach the minimum degree of (1-2) milligram/rice 3, thereby can not pollute surrounding environment.

In sum, working mechanism of the present utility model and process are for adopting the double action of selection by winnowing and screening, when by the grain cleared up when the exit of hopper falls, clean through the wind-force of induced-draught fan 11 earlier, fall within except that on the big assorted coarse meshed sieve body 4 after removing frivolous impurity, because sieve nest constantly swings back and forth under the effect of crank and rocker mechanism, make grain and small impurities from the grid of sieve nest, fall to the clean grain detailed catalogue sieve nest of lower floor, big impurity is then screened out by the sieve nest on upper strata, and grain flows when swinging back and forth from top to bottom on clean grain detailed catalogue sieve nest.Less than the small impurities of the sieve aperture of clean grain detailed catalogue sieve nest 5 or crack rice to be removed by shake and land, thereby evenly neat clean grain then mouthful flows out from putting out cereal and reaches the purpose of grain clearly.Shrivelled kernel that is cleared and clever base are commonly called as useful materials such as rice sprout point and also can be used as the raw material of making feed.

Simultaneously, the utility model only need be changed corresponding compass screen surface and can clear up granulated crops such as wheat, paddy, corn, beans, rapeseed.
