Description

Technical Field

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

[0002] Rice, also known as paddy rice, is a food made from paddy through processes such as cleaning, hulling, milling, and finishing. It is widely used in various foods and dishes. During the production and processing of rice, it is necessary to screen the rice to separate impurities, broken rice, and other grains that do not meet quality requirements, thereby improving the quality and purity of the rice.

[0003] Chinese utility model patent application number CN202420758353.7 discloses a rice screening device for rice production. The utility model describes that "the utility model sets up a screening component, specifically by turning on the motor to drive cam one and cam two to rotate, causing the screening plate to move upward. After the protruding part separates from the bottom of the screening plate, spring one and spring two will pull the screening plate downward due to the tension, so that the screening device can quickly screen and completely screen out broken rice in the rice, thereby improving the overall quality of the rice."

[0004] This rice screening device for rice production uses a screening assembly to drive a screening plate to vibrate, and then pours the rice into a feeding hopper. The screening plate screens the rice. However, when the rice has a high moisture content, the surface becomes sticky. When poured into the inverted funnel-shaped feeding hopper, it easily adheres to the inner wall. Some impurities are inherently sticky, such as impurities containing sugar or sticky impurities produced by fermentation. When these impurities are mixed with the rice and poured into the feeding hopper, they also easily adhere to the inner wall, requiring cleaning, which is time-consuming and labor-intensive, affecting the performance. Therefore, a rice screening device for production is proposed to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a screening device for rice production, which has advantages such as good performance. It solves the problem that rice or impurities easily adhere to the inner wall, requiring cleaning, which is time-consuming and laborious, thus affecting the performance.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a screening device for rice production, comprising a screening mechanism, a vibration mechanism connected to the bottom of the screening mechanism, a cover detachably installed on the top of the screening mechanism, a feed hopper connected to the top of the cover, and an impact mechanism extending into the feed hopper connected to the top of the cover.

[0007] Furthermore, the screening mechanism includes a chamber, an annular plate is fixedly installed inside the chamber, a filter plate is detachably installed on the top of the annular plate, an mounting plate is detachably installed on the top of the filter plate, and a first discharge pipe and a second discharge pipe are connected to the bottom of the chamber.

[0008] Furthermore, the mounting plate is L-shaped, and the mounting plate is threadedly connected to the inner wall of the chamber by a first bolt, and the mounting plate is threadedly connected to the inside of the filter plate and the inside of the annular plate by a second bolt.

[0009] Furthermore, the vibration mechanism includes a connecting seat, which is fixedly connected to the bottom of the chamber body. A spring is fixedly installed at the bottom of the connecting seat, and a base is fixedly installed at the bottom of the spring. A vibration chamber is fixedly installed at the bottom of the chamber body, and a vibration motor is fixedly installed on the outside of the vibration chamber.

[0010] Furthermore, a hook is fixedly installed on the outer wall of the compartment, and a ring is fixedly installed on the outer wall of the cover, with the hook and the ring matching.

[0011] Furthermore, the top of the feed hopper is inverted funnel shape, and the bottom of the feed hopper is cylindrical shape.

[0012] Furthermore, the impact mechanism includes an electric push rod, which is fixedly connected to the top of the cover. A movable plate is fixedly installed at the output end of the electric push rod. A movable rod is fixedly installed on the side of the movable plate away from the output end of the electric push rod through the feed hopper. A connecting rod is fixedly installed on the outside of the movable rod, and an impact block is fixedly installed on the side wall of the connecting rod.

[0013] Furthermore, there are multiple connecting rods and multiple impact blocks. The multiple connecting rods and impact blocks are divided into two groups, and the two groups of impact blocks are used to impact the two inner walls of the feed hopper.

[0014] Furthermore, a dispersing mechanism is connected to the impact mechanism.

[0015] Compared with the prior art, the technical solution of this application has the following beneficial effects: This rice production screening device consists of a screening mechanism, a vibration mechanism, a cover, a feeding hopper, and an impact mechanism. The vibration mechanism drives the screening mechanism, cover, feeding hopper, and impact mechanism to vibrate, while the impact mechanism strikes the inner wall of the feeding hopper.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1 Please see Figure 1This embodiment of a rice production screening device includes a screening mechanism 1, a vibration mechanism 2 connected to the bottom of the screening mechanism 1, a cover 3 detachably installed on the top of the screening mechanism 1, a hook fixedly installed on the outer wall of the hopper 11, and a ring fixedly installed on the outer wall of the cover 3. The hook and the ring match to form a latch. The top of the cover 3 is connected to a feed hopper 4. The top of the feed hopper 4 is inverted funnel-shaped, and the bottom of the feed hopper 4 is cylindrical. The top of the cover 3 is connected to an impact mechanism 5 extending into the feed hopper 4.

[0020] Specifically, the staff first uses the vibration mechanism 2 to drive the screening mechanism 1, the cover 3, the feeding hopper 4 and the impact mechanism 5 to vibrate, and then uses the impact mechanism 5 to impact the inner wall of the feeding hopper 4. Then, the rice is poured into the inside of the feeding hopper 4, and the screening mechanism 1 screens the rice and impurities. The rice or impurities are not easy to adhere to the inner wall of the feeding hopper 4, which reduces the difficulty of cleaning, saves time and effort, and improves the use effect.

[0021] Please see Figure 2 In this embodiment, the screening mechanism 1 includes a chamber 11. An annular plate 12 is fixedly installed inside the chamber 11. A filter plate 13 is detachably installed on the top of the annular plate 12. An mounting plate 14 is detachably installed on the top of the filter plate 13. The mounting plate 14 is L-shaped. The mounting plate 14 is threadedly connected to the inner wall of the chamber 11 by a first bolt. The mounting plate 14 is threadedly connected to the inside of the filter plate 13 and the inside of the annular plate 12 by a second bolt. The bottom of the chamber 11 is connected to a first discharge pipe 15 and a second discharge pipe 16.

[0022] Specifically, rice is poured onto the top of the filter plate 13, which filters the rice. The rice is discharged through the first discharge pipe 15, while impurities pass through the filter plate 13 and are discharged through the second discharge pipe 16.

[0023] Please see Figure 3 In this embodiment, the vibration mechanism 2 includes four connecting seats 21, all four connecting seats 21 are fixedly connected to the bottom of the chamber 11, and springs 22 are fixedly installed at the bottom of each of the four connecting seats 21. The bottom of the four springs 22 is fixedly installed with a base 23. A vibration chamber 24 is fixedly installed at the bottom of the chamber 11, and two vibration motors 25 are fixedly installed on the outside of the vibration chamber 24.

[0024] Specifically, by turning on the two vibration motors 25, the two vibration motors 25 drive the vibration chamber 24 and the chamber body 11 to vibrate, and the four springs 22 are deformed by the force.

[0025] Please see Figure 4-5In this embodiment, the impact mechanism 5 includes an electric push rod 51, which is fixedly connected to the top of the cover 3. A movable plate 52 is fixedly installed at the output end of the electric push rod 51. A movable rod 53 is fixedly installed on the side of the movable plate 52 away from the output end of the electric push rod 51 through the feed hopper 4. Multiple connecting rods 54 are fixedly installed on the outside of the movable rod 53. The multiple connecting rods 54 are L-shaped. Impact blocks 55 are fixedly installed on the side walls of the multiple connecting rods 54. The multiple impact blocks 55 are all made of rubber. The multiple connecting rods 54 and impact blocks 55 are divided into two groups. The two groups of impact blocks 55 are used to impact the two inner side walls of the feed hopper 4 respectively.

[0026] Specifically, by activating the electric push rod 51, the electric push rod 51 drives the moving plate 52, the moving rod 53, the connecting rod 54 and the impact block 55 to move, so that the impact block 55 impacts the two inner walls of the feed hopper 4, causing the feed hopper 4 to vibrate, making it difficult for rice or impurities to adhere to the inner walls of the feed hopper 4.

[0027] The working principle of the above embodiments is as follows: The staff first turns on two vibration motors 25, which drive the vibration chamber 24, chamber body 11, cover 3 and feed hopper 4 to vibrate. The four springs 22 deform under force and activate the electric push rod 51. The electric push rod 51 drives the moving plate 52, moving rod 53, connecting rod 54 and impact block 55 to move, so that the impact block 55 impacts the two inner walls of the feed hopper 4, and the feed hopper 4 vibrates further. Then the rice is poured into the inside of the feed hopper 4. The filter plate 13 filters the rice and discharges it through the first discharge pipe 15. Impurities pass through the filter plate 13 and are discharged through the second discharge pipe 16. Rice or impurities are less likely to adhere to the inner wall of the feed hopper 4, reducing the difficulty of cleaning, saving time and effort, and improving the use effect.

[0028] Example 2 Please see Figure 4-5 The difference between Embodiment 2 and Embodiment 1 is that a dispersing mechanism 6 is connected to the impact mechanism 5. The dispersing mechanism 6 includes multiple vertical rods 61, which are all fixedly connected to the side wall of the moving rod 53. Multiple dispersing rods 62 are fixedly installed on the side of the multiple vertical rods 61 away from the moving rod 53. Multiple horizontal plates 63 are fixedly installed on the side wall of the multiple dispersing rods 62. The side of the multiple horizontal plates 63 away from the multiple dispersing rods 62 is in contact with the inner side wall of the feed hopper 4.

[0029] Specifically, when the moving rod 53 moves the vertical rod 61, the dispersing rod 62 and the horizontal plate 63, the dispersing rod 62 disperses the rice, making it less likely for the rice to pile up.

[0030] The working principle of the above embodiments is as follows: The operator first turns on two vibration motors 25, which drive the vibration chamber 24, chamber body 11, cover 3, and feed hopper 4 to vibrate. The four springs 22 deform under the force, and the electric push rod 51 is activated. The electric push rod 51 drives the moving plate 52, moving rod 53, connecting rod 54, impact block 55, vertical rod 61, dispersing rod 62, and horizontal plate 63 to move, so that the impact block 55 impacts the two inner walls of the feed hopper 4, and the feed hopper 4 vibrates further. Then, rice is poured into the interior of the feed hopper 4. The dispersing rod 62 disperses the rice, making it less likely to accumulate. The filter plate 13 filters the rice, and the rice is discharged through the first discharge pipe 15. Impurities pass through the filter plate 13 and are discharged through the second discharge pipe 16. Rice or impurities are less likely to adhere to the inner wall of the feed hopper 4, reducing the difficulty of cleaning, saving time and effort, and improving the use effect.
