Abstract

The invention provides an automatic rice screener and a rice screening method. The automatic rice screener comprises a side plate, a hopper, a blow mechanism and a screening mechanism, wherein the hopper, the blow mechanism and the screening mechanism are disposed on the side plate sequentially from top to bottom. The blow mechanism comprises a motor and fan blades, wherein the motor is disposed on the side plate and the fan blades are driven to rotate by the motor. The screening mechanism comprises a screen holder reciprocating below the hopper and a screen which is nested in the screen holder and which moves with the screen holder. One end of the screen holder is provided with a rectangular guide groove. A guide post driven by a drive device to do circular motion constantly is disposed inside the guide groove. When the guide post does circular motion, the guide post contacts with two long sides of the guide groove, perpendicular to a slide, by turns, and the screen holder is pushed to reciprocate along the slide; the fan blades disposed on the side of grains falling from the hopper to the screen blow air towards the grains. The grains are automatically screened twice by the mechanical device, so that impurities inside can be screened and clean grains are obtained; the whole process is efficient and saves energy.

The accompanying drawing explanation

Fig. 1 is Automatic sieve rice apparatus structure schematic diagram.

The specific embodiment

Below in conjunction with accompanying drawing and example, the present invention is further described.

Automatic sieve rice device of the present invention, as shown in Figure 1, comprise side plate 13, by sleeve 2, be fixed on funnel 1, inflatable body, rice screening mechanism and the refuse collecting case 12 on side plate 13.

Sleeve 2 is fixed on side plate 13 topmosts, and funnel 1 is fixed in sleeve 2, sets gradually inflatable body, rice screening mechanism downwards, and refuse collecting case 12 is fixed on side plate 13 foots.

Inflatable body comprises motor 3 and the flabellum 4 rotated by motor 3 drivings, and motor 3 is fixed on side plate 13.Flabellum 4 is arranged on the side direction between funnel 1 and sieve 6.The cereal leaked towards sieve 6 from funnel 1 is in dropping process, and the air-flow produced by the flabellum 4 rotated drives, and the foreign material of a part of lighter weight are separated with the cereal of lower leakage as weeds etc., realizes screening for the first time.

Rice screening mechanism comprises and is positioned at the sieve 6 that funnel 1 time can side-to-side movement, and the cereal leaked down from funnel 1 falls into the sieve 6 of motion.Sieve 6 removably is nested on sieve seat 5, and sieve seat 5 is placed on two parallel slide rails 7 and can horizontally slips along slide rail 7.

The side-to-side movement of sieve seat 5 promotes to realize by the circular motion of guide pillar 8.The guide groove 51 that one end of sieve seat 5 is a rectangle, the long limit 511 of guide groove 51 is vertical with slide rail 7, and the minor face 512 of guide groove 51 is parallel with slide rail 7, and guide pillar 8 is arranged in guide groove 51, by the long limit 511 of guide groove 51, the rectangle frame that minor face 512 surrounds, is enclosed in wherein.Guide rod 9 is horizontally disposed shaft, the driving shaft of one end and electric rotating machine 10 is hinged, its other end is fixedly connected with the guide pillar 8 of a cylindrical shape, electric rotating machine 10 drives guide rod 9 and is rotated centered by motor driving shaft, simultaneously, drive guide pillar 8 circles around the driving shaft of electric rotating machine 10; Guide pillar 8 is when circular motion, and wheel touches the long limit 511 of guide groove 51 with staying, longer because growing limit 511, and touch less than minor face 512, therefore, wheel stays ground respectively to left and right two that touch guide groove 51 long limits 511, thus promote sieve seat 5 along slide rail 7 to left and right moving.Electric rotating machine 10 is fixed on the side plate 13 between two one slide rails 7 by motor fixing plate 11.

Sieve seat 5 lower surfaces have been made the circular hole that diameter is less than general cereal, can be through the foreign material that fallen by sieve 6 eyelets, but the particle diameter less cereal fallen through sieve 6 eyelets is caught by sieve seat 5 lower surfaces, avoids the cereal that particle diameter is less to be sifted out disappearance.

In other embodiments, sieve seat 5 can be also frame structure, nested sieve 6 on framework, and the foreign material that fallen by sieve 6 eyelets directly fall into refuse collecting case 12.

When sieve 6 is carrying cereal and ceaselessly moves, wherein the size foreign material little than cereal of carrying spill from sieve 6, and the circular hole of the foreign material that sieve out on sieve seat 5 lower surfaces falls into refuse collecting case 12, thereby realize screening for the second time.Sieve 6 can be taken out from sieve seat 5 after the screening through after a while, the purer cereal obtained after screening on sieve 6 is collected.

For collect better the foreign material that sieve out from sieve 6, it is longer that refuse collecting case 12 arranges, and can comprise the whole range of movement of sieve 6 side-to-side movements.

The method that adopts Automatic sieve rice device to sieve rice comprises the following steps:

Step 1, cereal or other grain that airing is good are poured in funnel 1 in right amount;

In step 2, the process of leaking under by funnel 1 lower end at cereal, under the air-flow that the flabellum 4 rotated in inflatable body produces drives, the foreign material of a part of lighter weight are separated with cereal as weeds etc., realize screening for the first time;

Step 3, electric rotating machine 10 constantly rotate and make the guide pillar 8 be connected with electric rotating machine 10 by guide rod 9 carry out circular motion, guide pillar 8 is taken turns promotion sieve seat 5 with staying and is continued to left and right moving along slide rail 7, thereby drive the cereal relative motion in sieve 6 nested on sieve seat 5, the little foreign material of size just spill from the eyelet of sieve 6 and the circular hole sieve seat 5 lower surfaces, thereby realize screening for the second time;

Step 4, the foreign material that sieve out fall into the convenient cleaning of refuse collecting case 12, after the screening of a period of time, sieve 6 can be taken out from sieve seat 5, and the purer cereal obtained after screening on sieve 6 is collected simultaneously.

Above-mentioned steps 2 and step 3 are committed step of the present invention, the foreign material sieve in cereal can be removed by 2 screenings, thereby obtain clean cereal, have the characteristics such as efficient, energy-conservation, that cost is low.
