Detailed Description

The present invention will be further described with reference to the following examples and accompanying drawings, it being understood that the following detailed description is illustrative of the invention only and is not intended to limit the scope of the invention. It should be noted that the terms "front," "back," "left," "right," "upper" and "lower" used in the following description refer to directions in the drawings, and the terms "inner" and "outer" refer to directions toward and away from, respectively, the geometric center of a particular component.

As shown in figure 1, the feeding and filtering device for rice processing comprises an auger conveyor 1 and a filtering box 2; the auger conveyor 1 comprises a motor 3 and a machine groove 4, the upper end of the machine groove 4 is provided with a feed inlet 5 and a dust removing port 6, an exhaust fan 7 is arranged at the dust removing port 6, the motor 3 is positioned at one side of the machine groove 4 and is connected with a helical blade in the machine groove 4, the end face at the other side of the machine groove 4 is provided with a discharge port 8, the discharge port 8 extends into the filter box 2, a vibrating screen 9 is arranged in the filter box 2, the vibrating screen 9 is positioned below the discharge port 8, one end of the vibrating screen 9 is fixed on the side wall of the filter box 2 through a bolt, the other end of the vibrating screen 9 extends out of the filter box 2 and is connected with a vibrator 10 fixed on the outer side of the filter box 2, the vibrating screen 9 is provided with an upper screen 901 and a lower screen 902, the upper screen 901 is connected on the vibrating screen 9 in a telescopic manner, the lower screen 902 is fixedly connected on the vibrating screen 9, the upper screen 901 is divided into a small screen, the aperture of the small net a903 is 0.5-1.5mm, the screen of the lower sieve 902 is divided into two types, namely a small net b905 and a large net 906, the aperture of the small net b905 is 0.5-1.5mm, the aperture of the large net 906 is 2-4mm, the small net a903 and the small net b905 are overlapped, the solid plate 904 and the large net 906 are overlapped, a soft material guide pipe 11 is further arranged below the lower sieve 902, the part below the vibrating sieve 9 in the filter box 2 is divided into two bins by a partition plate, one of the two bins is a rice bin 13, the other of the two bins is an impurity bin 12, the soft material guide pipe 11 connected with the small net b905 of the lower sieve 902 stretches into the impurity bin 12, the soft material guide pipe 11 connected with the large net 906 of the lower sieve 902 stretches into the large rice bin 13, a rice outlet 14 is arranged at the bottom of the large rice bin 13, and a conveying belt 15 is arranged below the rice outlet 14.

The principle of the invention is as follows: the rice to be filtered can remove dust through the action of an exhaust fan in the process of conveying the rice to a filter box in an auger conveyor, the rice enters a vibrating screen for screening after entering the filter box, an upper screen is not drawn out, only a superposed small net a and a superposed small net b on the vibrating screen have a channel, and a superposed solid plate and the superposed large net have no channel, so that impurities such as sand and stones with smaller diameters than the rice enter an impurity bin through a soft material guide pipe, the impurities with smaller diameters are filtered after vibrating for a period of time and are drawn out of the upper screen, only a lower screen exists at the moment, the rice can enter a large rice bin through the soft material guide pipe only through the channel of the large net, the impurities with larger diameters are directly left on the vibrating screen for accumulation in a certain amount and are subjected to centralized treatment, and thus the impurities with smaller diameters are removed, and the impurities with. The filtered rice is poured out from the rice outlet and conveyed to the next procedure by a conveyer belt.

As an embodiment of the present invention, there are nine screen meshes of the upper screen 901 and the lower screen 902, and the small net a903 and the solid plate 904, and the small net b905 and the large net 906 are arranged at intervals. The interval arrangement can ensure that filtration everywhere is carried out simultaneously, prevents to lead to some places to filter because of the filtration passageway is too concentrated.

In one embodiment of the present invention, the volume ratio of the trash bin 12 to the rice bin 13 is 1: 3. Because the impurity proportion in the rice is not large, the impurity bin does not need overlarge volume.

As an embodiment of the invention, the rice outlet 14 at the bottom of the rice bin 13 is in a conical funnel shape. The rice outlet can ensure that the rice is completely poured out of the rice bin under the action of gravity.

The feeding and filtering device for rice processing provided by the invention can automatically feed and remove dust for rice, can filter the rice, can automatically disperse and collect the rice and impurities, is high in production efficiency, and can greatly improve the quality of the rice.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way, but any modifications or equivalent variations made according to the technical spirit of the present invention are within the scope of the present invention as claimed.
