Description

A screening device for rice production and processing Technical Field

[0001] This utility model relates to the field of screening device technology, specifically a screening device for rice production and processing. Background Technology

[0002] Raw rice grains may contain impurities such as stones and sand, which can affect the taste and safety of the rice. These impurities can be removed by sieving during processing.

[0003] When using screening equipment for rice production and processing, traditional screening methods generally use vibrating screens, which often result in spillage or inaccurate screening due to excessive material input at one time. This requires manual cleaning afterward, thus reducing the efficiency of the equipment. Summary of the Invention

[0004] The purpose of this utility model is to provide a screening device for rice production and processing, in order to solve the problems mentioned in the background art. Traditional screening methods generally use vibrating screens for screening, which often result in spillage or inaccurate screening due to too much material being fed at once, requiring manual cleaning afterwards, thus reducing the efficiency of the equipment.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sieving device for rice production and processing, comprising a device body, a motor fixedly connected to the inner wall of one side of the device body, a first spiral feeder fixedly welded to the output shaft of the motor, a feeder fixedly connected between the inner walls of the front and rear sides of the device body via a fixed rod, and the feeder being rotatably connected to the first spiral feeder, a fixed short rod fixedly welded to one end of the first spiral feeder, a second spiral feeder fixedly welded to one end of the fixed short rod, a first screen cylinder sleeved on the outer surface of the second spiral feeder, and the first screen cylinder being rotatably connected to the second spiral feeder and fixedly connected to the device body, and a plurality of first filter holes being opened near the bottom on the outer surface of the first screen cylinder.

[0006] In a preferred embodiment, two fixed transmission blocks are fixedly welded to the outer surface of the fixed short rod, and a second screen cylinder is fixedly sleeved between the opposite ends of the two fixed transmission blocks.

[0007] In a preferred embodiment, the outer surface of the second screen cylinder is provided with a plurality of second filter holes, and the inner wall of the second screen cylinder is fixedly welded with a third spiral feeder, which is rotatably connected to the first screen cylinder.

[0008] In a preferred embodiment, the device body is provided with a dust collection tank inside.

[0009] In a preferred embodiment, a first discharge port is provided on one outer surface of the device body, and the first discharge port is connected to the first screen cylinder.

[0010] In a preferred embodiment, a second discharge port is provided on one side of the outer surface of the device body near the edge of the first discharge port, and the second discharge port is connected to the second screen cylinder.

[0011] In a preferred embodiment, a dust discharge port is provided on one side of the outer surface of the device body near the bottom edge, and the dust discharge port is connected to the dust collection tank.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention first involves starting a motor and pouring unscreened rice into the feeder. The motor's operation drives the first screw feeder to rotate, evenly guiding the unscreened rice into the first sieve cylinder. A fixed short rod is used so that the rotation of the first screw feeder, driven by the motor, simultaneously rotates both the fixed short rod and the second screw feeder. The rotation of the second screw feeder further evenly transfers the rice layer by layer within the first sieve cylinder. Through the design of the first sieve cylinder and the first filter holes, combined with the rotation of the second screw feeder, whole grains, broken grains, and dust are sieved out through the first filter holes into the second sieve cylinder, leaving only the unhulled rice in the first sieve cylinder. Inside, unhulled rice grains can be discharged from the first screen cylinder through the first discharge port. With the fixed transmission block, the rotation of the fixed short rod can drive the second screen cylinder to rotate synchronously. When the second screen cylinder and the third screw feeder rotate, broken rice and dust inside the second screen cylinder can be screened out through the second filter holes into the dust collection trough, leaving only whole rice grains inside the second screen cylinder. The whole rice grains inside the second screen cylinder can be discharged through the second discharge port, while broken particles and dust inside the dust collection trough can be discharged through the dust discharge port. Compared with vibrating screen screening, the screening process is uniform, simple, and efficient, and is relatively sealed to prevent spillage, thus improving the working efficiency of the equipment.

[0019] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0020] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0021] Please refer to Figures 1-4. This utility model provides a technical solution: a sieving device for rice production and processing, including a device body 1. A motor 2 is fixedly connected to the inner wall of one side of the device body 1. By starting the motor 2, a first screw feeder 3 can be driven to rotate. The output shaft of the motor 2 is fixedly welded to the first screw feeder 3. The rotation of the first screw feeder 3 allows the rice inside the feeder 4 to be evenly introduced into the interior of the first sieve cylinder 7. The feeder 4 is fixedly connected between the inner walls of the front and rear sides of the device body 1 by a fixing rod, and the feeder 4 is rotatably connected to the first screw feeder 3. The feeder 4 allows rice to be poured in. A fixing short rod 5 is fixedly welded to one end of the first screw feeder 3. By fixing the short rod 5, when the motor 2 drives the first screw feeder 3 to rotate, the feeder 4 can be evenly introduced into the interior of the first sieve cylinder 7. While the screw feeder 3 rotates, it can drive the fixed short rod 5 and the second screw feeder 6 to rotate. The second screw feeder 6 is fixedly welded to one end of the fixed short rod 5. The rotation of the second screw feeder 6 can evenly transfer the rice inside the first screen cylinder 7 layer by layer. The outer surface of the second screw feeder 6 is fitted with the first screen cylinder 7, and the first screen cylinder 7 and the second screw feeder 6 are rotatably connected and fixedly connected to the device body 1. The outer surface of the first screen cylinder 7 is provided with a plurality of first filter holes 8 near the bottom. Through the arrangement of the first screen cylinder 7 and the first filter holes 8, in conjunction with the rotation of the second screw feeder 6, whole grains, broken grains and dust in the rice can be screened out from the first filter holes 8 into the second screen cylinder 10, leaving only the unhulled rice inside the first screen cylinder 7.

[0022] Two fixed transmission blocks 9 are fixedly welded to the outer surface of the fixed short rod 5. With the fixed transmission blocks 9, when the fixed short rod 5 rotates, the fixed transmission blocks 9 can drive the second screen cylinder 10 to rotate synchronously. The second screen cylinder 10 is fixedly sleeved between the opposite ends of the two fixed transmission blocks 9. The rotation of the second screen cylinder 10 can drive the third screw feeder 12 to rotate. The outer surface of the second screen cylinder 10 is provided with multiple second filter holes 11. Since the diameter of the second filter holes 11 is smaller than that of the first filter holes 8, when the second screen cylinder 10 and the third screw feeder 12 rotate, the broken rice and dust in the second screen cylinder 10 can be screened out from the second filter holes 11 into the dust collection tank 13, leaving only the whole rice inside the second screen cylinder 10. The third screw feeder 12 is fixedly welded to the inner wall of the second screen cylinder 10, and the third screw feeder 12 is rotatably connected to the first screen cylinder 7.

[0023] The device body 1 has a dust collection tank 13 inside, which can collect the broken rice and dust sifted out by the second sieve cylinder 10. A first discharge port 14 is opened on one side of the outer surface of the device body 1 and is connected to the first sieve cylinder 7. Unhulled rice grains inside the first sieve cylinder 7 can be discharged through the first discharge port 14. A second discharge port 15 is opened on one side of the outer surface of the device body 1 near the edge of the first discharge port 14 and is connected to the second sieve cylinder 10. Whole rice grains inside the second sieve cylinder 10 can be discharged through the second discharge port 15. A dust discharge port 16 is opened on one side of the outer surface of the device body 1 near the bottom edge and is connected to the dust collection tank 13. Broken particles and dust inside the dust collection tank 13 can be discharged through the dust discharge port 16.

[0024] Working Principle: When using the rice processing screening device, firstly, by starting the motor 2, unscreened rice is poured in through the feeder 4. The starting of the motor 2 drives the first screw feeder 3 to rotate, thus evenly guiding the unscreened rice into the interior of the first screen cylinder 7. Due to the fixed short rod 5, when the motor 2 drives the first screw feeder 3 to rotate, it also drives the fixed short rod 5 and the second screw feeder 6 to rotate. The rotation of the second screw feeder 6 evenly transfers the rice layer by layer inside the first screen cylinder 7. Through the arrangement of the first screen cylinder 7 and the first filter holes 8, combined with the rotation of the second screw feeder 6, whole grains, broken grains, and dust in the rice are screened out through the first filter holes 8 and into the second screen cylinder 10, retaining only the unhulled paddy rice. Inside the sieve cylinder 7, unhulled rice grains can be discharged through the first discharge port 14. With the fixed transmission block 9, when the fixed short rod 5 rotates, the fixed transmission block 9 can drive the second sieve cylinder 10 to rotate synchronously. When the second sieve cylinder 10 and the third screw feeder 12 rotate, the broken rice and dust inside the second sieve cylinder 10 can be screened out through the second filter hole 11 into the dust collection trough 13, leaving only whole rice inside the second sieve cylinder 10. The whole rice grains inside the second sieve cylinder 10 can be discharged through the second discharge port 15, while the broken particles and dust inside the dust collection trough 13 can be discharged through the dust discharge port 16. Compared with vibrating screen screening, the screening process is uniform, simple and efficient, and relatively sealed to prevent spillage, thus improving the working efficiency of the equipment.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
