Technical Field

[0001] The utility model relates to the technical field of rice production, in particular to a dregs auxiliary screening device for rice production and processing. Background Art

[0002] Rice is a finished product made from paddy rice after processes such as cleaning, husking, milling, and finished product sorting. The cleaning process is to use suitable equipment, appropriate process flow and proper operation methods to remove various impurities mixed in the rice to improve the quality of the finished rice product. At the same time, magnets are used to remove iron nails, iron filings, etc. in the rice to ensure production safety. After the rice husking process, a certain amount of broken rice will be produced. At this time, a screening device is needed to screen the broken rice in the rice.

[0003] Most of the existing rice screening is done manually to separate the impurities in the rice. The screening speed is slow, the workload is large, it is time-consuming and labor-intensive, and the production cost is high. The traditional screening equipment is driven by a cam, which causes large equipment wear, high failure rate, and troublesome maintenance, which can easily affect the production speed and cause economic losses. Utility Model Content

[0005] The technical effect of adopting the above-mentioned further scheme is: pour the rice into the interior of the screening box, and then start the motor through an external power supply. At this time, the motor drives the reciprocating screw to rotate. At this time, the slide plate slides back and forth on the outer surface of the reciprocating screw under the limit of the limit rod, and drives the rollers on both sides to roll inside the rolling groove when sliding. When rolling, because the rolling groove is in an inclined state, the angle is 30 degrees. At this time, the screening box moves back and forth up and down under the limit of the spring and the damper, and the roller rolls on the surface of the protrusion, causing the screening box to vibrate.

[0006] As a preferred embodiment, rolling grooves are provided inside the two triangular blocks, and a plurality of protrusions are fixedly connected to the outer surfaces of the two rolling grooves. The outer surface of the support frame is fixedly connected to an L-bar, and the outer surface of the support frame is fixedly connected to a support plate. The outer surface of the L-bar is fixedly connected to a motor, and the output end of the motor is fixedly connected to a reciprocating screw.

[0007] The technical effect of adopting the above further solution is: the motor is started by an external power supply, and the motor drives the reciprocating screw to rotate. At this time, the slide slides back and forth on the outer surface of the reciprocating screw when the limit rod is limited.

[0008] As a preferred embodiment, the end of the reciprocating screw away from the motor is rotatably connected to the outer surface of the support plate through a bearing, the outer surface of the support plate on the side opposite to the L-bar is fixedly connected to a limit rod, and the limit rod and the outer surface of the reciprocating screw are movably sleeved with a slide, and the outer surface of the slide close to both sides is fixedly connected to rollers.

[0009] The technical effect of adopting the above further solution is that the slide slides back and forth on the outer surface of the reciprocating screw rod when the limit rod is limited, so as to limit the position of the slide.

[0010] As a preferred embodiment, the two rollers roll inside the two rolling grooves, and the outer surface of the support plate is fixedly connected with a V-shaped baffle, which is located directly above the limit rod and the reciprocating screw rod, and the V-shaped baffle is located directly below the screening box and does not contact the screening box.

[0011] The technical effect of adopting the above-mentioned further solution is: the V-shaped baffle is fixed on the surface of the support plate and is located directly above the reciprocating screw and the limit rod, which can block the rice falling from the screening box and prevent the rice from getting stuck on the surface of the reciprocating screw when the slide slides.

[0012] As a preferred embodiment, the outer surface of the support frame near its four sides are fixedly connected with support feet, and a material receiving box is provided directly below the support frame.

[0013] The technical effect of adopting the above further solution is: to support the entire device.

[0014] Compared with the prior art, the advantages and positive effects of the present invention are:

[0015] 1. When the utility model is in use, rice is poured into the interior of the screening box, and then the motor is started by an external power supply. At this time, the motor drives the reciprocating screw to rotate. At this time, the slide plate slides back and forth on the outer surface of the reciprocating screw rod when it is limited by the limit rod, and drives the rollers on both sides to roll inside the rolling groove when sliding. When rolling, because the rolling groove is in an inclined state with an angle of 30 degrees, the screening box is limited by the spring and the damper to move back and forth up and down, and the roller rolls on the surface of the protrusion, so that the screening box vibrates. The rice inside the screening box is screened by the vibration of the screening box and enters the interior of the receiving box from the small hole inside for collection.

[0016] 2. When the utility model is in use, the V-shaped baffle is fixed to the surface of the support plate and is located directly above the reciprocating screw and the limit rod, which can block the rice falling from the screening box and prevent the rice from getting stuck on the surface of the reciprocating screw when the slide plate slides.
