Description

Rice sieving mechanism

Technical Field

The invention relates to the technical field of grain processing, in particular to a rice screening device.

Background

Rice is the staple food for southern people. The rice is obtained in a very simple process, and the dried rice can be directly hulled to obtain white rice. The husking of rice is usually performed by mechanical equipment, commonly called "rice husking", which is usually performed by crushing or breaking rice. Therefore, according to different qualities, rice is divided into high-quality rice and poor-quality rice, the high-quality rice with good appearance and no breakage is high-quality rice, and the poor-quality rice with breakage is poor-quality rice.

In rural areas, ground rice cannot be distinguished, but a rice processing factory can distinguish high-quality rice from low-quality rice in order to increase the sales volume of the rice. To obtain high quality rice, the milled rice needs to be screened, and the existing screening method generally uses a screen to screen.

Because the mode of screening is through the screen cloth screening, and rice husk can both pass through the screen cloth during the screening process, consequently can have the problem of entering rice of poor quality with the shell sieve of corn, still need carry out the screening to rice of poor quality for the second time in order to sift out the rice husk once more, so that rice of poor quality can be sold. The double screening of the rice undoubtedly increases the workload of processing, thereby reducing the working efficiency.

Detailed Description

The invention is further explained with reference to the drawings and the embodiments.

Referring to fig. 1: the utility model provides a rice sieving mechanism, is equipped with the air-blower including the spout 1 that the slope set up, one side of spout, is equipped with in the below of spout and carries the platform, carry the conveyer belt that the platform includes the motor at both ends and locates the axle outside of motor, be equipped with small opening 31 on the conveyer belt, the below of conveyer belt is equipped with vibrating arm 5, vibrating arm 5 is connected with cylinder 7.

In this embodiment, support spout 1 through the support, spout 1 slope sets up, and inclination is 45, and this angle is favorable to the rice to flow downwards under the action of gravity, and is unlikely to again that flow velocity is too fast, and leads to the rice husk to blow unclean. The inner surface of the chute 1 is made into a smooth surface, which is beneficial to the flow of rice; the two sides of the sliding chute 1 are provided with first flanges 11, and one side of the sliding chute 1 is provided with an air blower for blowing air into the sliding chute 1, so that the air speed is controlled, rice hulls can be blown, and rice is prevented from being blown away; the height of first flange 11 is 2cm, and first flange 11 can weld on spout 1, and the setting of this height can avoid the both sides of rice spout 1 to flow out, is unlikely to block the rice husk that is blown away again. One side of 1 keeping away from the air-blower at spout is equipped with the rice husk and collects the cover, and the rice husk that should collect the cover can be collected the certain region in with being blown away, has reduced the degree of difficulty of follow-up cleaning.

In this embodiment, the upper end of the chute 1 is defined as an inlet end, and rice to be screened can be manually poured into the chute 1; the lower extreme of spout 1 is defined as exit end 12, and exit end 12 is the horn mouth, and the rice flows out from the exit end 12 of horn mouth and enters into on locating the conveyer belt 3 of spout 1 below, and this conveyer belt 3's mode of setting is similar with ordinary production line, utilizes two motors to make conveyer belt 3 cycle rotate. The horn mouth is arranged to enable the rice to enter the conveying belt 3 in a concentrated mode, so that the width of the conveying belt 3 can be reduced, and cost is reduced. The chute 1 is wide, so that the rice husk can be blown away conveniently by spreading a rice layer in the chute 1.

In this embodiment, exit end 12 of spout 1 is 5cm with the difference in height of conveyer belt 3, because if the difference in height is big, when the rice entered into conveyer belt 3, drops to the conveyer belt 3 outside easily, if the difference in height undersize, then can hinder the second flange that 3 both sides of conveyer belt set up, and the height of second flange is 2cm, in order to prevent that the rice from flowing out from the side, the second flange can glue on conveyer belt 3.

The vibrating rod 5 is arranged below the upper conveying belt, round rods can be selected from the vibrating rods, the vibrating rods are multiple and are arranged below the upper conveying belt at intervals, the vibrating rods are welded together through the cross beam 6, one end of the cross beam 6 is connected with the shaft of the air cylinder, and the shaft of the air cylinder 7 can move up and down under the action of the air cylinder, so that the vibrating rods can be driven to move up and down. When the vibrating arm was located the top, can be with conveyer belt jack-up 1cm, the range is little, can not let the rice on the conveyer belt fly away, can also realize the effect of artifical screen cloth with the rice vibration on the conveyer belt for rice can be followed the small opening on the conveyer belt and flowed down and enter into first containing box inferior.

In another embodiment, each vibrating rod is connected with one air cylinder, so that the independent ascending or descending of each vibrating rod can be realized, and the vibration efficiency is higher.

Be equipped with a plurality of small openings 31 on the conveyer belt 3, the diameter of small opening 31 is 5mm, makes things convenient for the size to be less than 5 mm's poor quality rice and falls down from small opening 31, enters into and locates in the first containing box 2 between the upper and lower conveyer belt 3. The first containing box 2 can be arranged by arranging upright columns at two sides or one side of the conveying belt 3, the upright columns are provided with hooks at the positions corresponding to the heights of the first containing box 2, and the first containing box 2 can be hung on the hooks; or a storage plate is directly welded on the upright column, and the first storage box 2 is placed on the storage plate. The high-quality rice falls from the end into the second storage box 4 provided therein along with the transportation of the conveyor belt 3.

Through the screening of above-mentioned process to blow away the rice husk, the rice husk enters into the rice husk and collects the cover in, and the rice of poor quality enters into first containing box 2, and high-quality rice enters into second containing box 4.

The present invention is not limited to the above embodiments, and various combinations and modifications of the above technical features may be provided for those skilled in the art, and modifications, variations, equivalents, or uses of the structure or method of the present invention in other fields without departing from the spirit and scope of the present invention are included in the protection scope of the present invention.
