Description

Technical Field

[0001] The utility model relates to the technical field of rice processing, in particular to a vibration selection device for rice processing. Background Art

[0002] Rice, also known as paddy rice, is a food made from rice grains after processes such as cleaning, husking, milling, and finished product sorting. In the process of rice production and processing, it is necessary to select grains and broken rice with a smaller diameter than standard rice, so as to leave high-quality rice. A selection machine is needed in the process of rice selection. Most of the existing rice selection machines use a motor to drive the screen to vibrate during the processing process, so as to screen out grains and broken rice with a smaller diameter than standard rice. This method of rice selection results in a lot of rice and broken rice with small diameters that cannot be accurately selected.

[0003] For example, Chinese patent publication number CN219129847U discloses a rice processing selection machine. When in use, the user first adds rice to a feed port, and then sends the rice to a broken rice selection drum through the feed port, and then starts the motor. The output end of the motor drives the first pulley to rotate, and the first pulley drives the second pulley to rotate through a belt, and the second pulley drives the rotating rod to rotate, and the rotating rod drives the broken rice selection drum to rotate. The rotating broken rice selection drum screens out particles smaller than the diameter of standard rice and broken rice through a broken rice filter and drops them into a collection box, and high-quality rice falls from the broken rice selection drum into a rectangular box and is discharged through a discharge port, thereby achieving the effect of selecting high-quality rice.

[0004] However, in the rice processing concentrator in the above application, the concentrator drum is not provided with a turning mechanism when rotating and concentrating, which may cause broken rice to be entrapped in the rice pile, thereby affecting the concentrating effect. Therefore, there are certain limitations.

[0005] For this reason, we urgently need to provide a kind of vibration selection device for rice processing. Utility Model Content

[0006] The utility model aims to provide a vibration selection device for rice processing, so as to solve the problem that the selection drum of the rice processing selection machine proposed in the above background technology is not provided with a turning mechanism when rotating and selecting, which may cause broken rice to be trapped in the rice pile, thereby affecting the selection effect.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a vibration selection device for rice processing, comprising a base and a selection box, wherein the selection box is obliquely installed on the base through supporting legs, and a screening device is arranged inside the selection box.

[0008] The cleaning device comprises a rotary screening unit, a turning unit and a cleaning unit.

[0009] The rotary screening unit includes a fixed bearing, a rotating motor, a rotating shaft, and a screening drum. The fixed bearing is installed above the left outer surface of the selection box, the rotating motor is installed on the left side of the selection box, the rotating shaft is connected to the output end of the rotating motor, and is rotatably connected to the inside of the fixed bearing. The screening drum is fixedly connected to the right end of the rotating shaft. Starting the rotating motor drives the rotating shaft to rotate inside the fixed bearing, thereby driving the screening drum to rotate inside the selection box, so as to perform rolling screening on the rice inside the screening drum.

[0010] A further improvement is that the turning unit includes a turning motor, a rotating bearing, a rotating shaft, and a turning auger. The turning motor is installed on the right inner wall of the selection box, the rotating bearing is installed on the right outer surface of the screening drum, the rotating shaft is connected to the output end of the turning motor, and is rotatably connected to the inside of the rotating bearing, and the turning auger is fixedly connected to the outer surface of the rotating shaft. While the screening drum rotates to screen the rice, the turning motor is started to drive the rotating shaft to rotate inside the rotating bearing, thereby driving the turning auger on the outer surface of the rotating shaft to rotate in the opposite direction inside the screening drum, thereby twisting the rice from the right side to the left side of the screening drum, turning the rice inside and outside, making it easier for broken rice and impurities inside the rice pile to roll out and be screened out, thereby improving the screening effect.

[0011] A further improvement is that a feed pipe is fixedly connected above the left outer surface of the screening drum, and a discharge pipe is fixedly connected below the right outer surface of the screening drum. Electric sealing valves are installed on the outside of the feed pipe and the discharge pipe. An external feed hopper is inserted into the feed pipe to add rice to the screening drum, and the screened full rice is discharged through the discharge pipe.

[0012] A further improvement is that a drainage block is fixedly connected to the inner right side of the selection box, and a discharge port is opened on the right outer surface of the selection box, and the discharged full rice falls onto the drainage block and is then discharged through the discharge port.

[0013] A further improvement is that the selection unit includes a screening plate, a vibration motor, and a tension spring. The screening plate is obliquely installed at the lower part of the selection box, and the vibration motor is installed on the bottom right side of the screening plate. The four tension springs are respectively fixedly connected to the four corners of the lower surface of the screening plate, and a bearing seat is installed at the bottom.

[0014] A further improvement is that screening holes are provided on the outer surfaces of the screening drum and the screening plate, and the diameter of the screening holes on the screening drum is larger than the diameter of the screening holes on the screening plate. The broken rice and impurities screened by the screening drum fall onto the screening plate, and then the vibration motor is started to drive the screening plate to vibrate up and down on the tension spring, thereby shaking off the impurities in the broken rice and completing the secondary selection.

[0015] A further improvement is that a discharge port is provided below the left outer surface of the selection box, drainage plates are fixedly connected to the left and right sides of the bottom of the selection box respectively, and a debris discharge port is provided at the bottom of the selection box, the broken rice after the secondary selection is discharged through the discharge port, and the impurities screened out from the broken rice are collected to the debris discharge port through the drainage plate for discharge.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] 1. The vibration selection device for rice processing starts the rotary motor to drive the rotary shaft to rotate inside the fixed bearing, thereby driving the screening drum to rotate inside the selection box, so as to roll and screen the rice inside the screening drum.

[0018] 2. The vibration selection device for rice processing starts a turning motor while the screening drum rotates to screen the rice, driving the rotating shaft to rotate inside the rotating bearing, thereby driving the turning auger on the outer surface of the rotating shaft to rotate in the opposite direction inside the screening drum, thereby twisting and sending the rice from the right side of the screening drum to the left side, stirring the rice inside and outside, making it easier for broken rice and impurities inside the rice pile to roll off and be screened out, thereby improving the screening effect.

[0019] 3. The vibrating selection device for rice processing, after being screened by the screening drum, the broken rice and impurities fall onto the screening plate, and then the vibration motor is started to drive the screening plate to vibrate up and down on the tension spring, thereby shaking off the impurities in the broken rice and completing the secondary selection.
