[0002] Rice is a food made from paddy through processes such as cleaning, hulling, milling, and finishing. During the initial processing of rice, it is often necessary to screen it to remove small impurities such as pebbles. However, most screening methods involve manual sieving using bamboo sieves, which is inefficient, labor-intensive, and not suitable for large-scale rice screening. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a screening device for the initial processing of rice.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A screening device for primary processing of rice includes a placement platform with a box body on the upper surface of the platform. The box body has an inner cavity with an opening in the middle. Bearings are symmetrically and rotatably mounted on the two side walls of the box body at the opening. A screening plate mechanism is mounted between the two bearings and rotates around the bearings. The screening plate mechanism is located at the opening.

[0006] The screening plate mechanism includes a screening plate, a rotating shaft is provided on one side of the screening plate, both ends of the rotating shaft are located at the inner ring of the bearing, and a baffle is fixedly connected to the other side of the rotating shaft away from the screening plate.

[0007] The screening plate is provided with a screen, and an outlet is provided on the other side of the screen away from the rotating shaft.

[0008] In addition, a preferred structure is that the bottom of the box body is provided with a first discharge port below the screening plate, and the top of the box body is provided with a feed port above the first discharge port.

[0009] In addition, a preferred structure is that a second discharge port is provided on the upper surface of the placement platform, the first discharge port is located above the second discharge port, and a collection box is placed on one side of the box body on the upper surface of the placement platform.

[0010] In addition, a preferred structure is that a waste outlet is provided on one side of the box, which is located above the collection box, and viewing windows are symmetrically provided on both side walls of the box.

[0011] In addition, a preferred structure is that a support plate is vertically arranged on the bottom wall of the inner cavity of the box on the side away from the first discharge port, one end of the screening plate abuts against the support plate, and a discharge plate is arranged on the side of the support plate away from the first discharge port.

[0012] In addition, a preferred structure is that a discharge port is provided on one side wall of the box at the discharge plate.

[0013] In addition, a preferred structure is that a pulse valve body is provided on one side wall of the box and on the side of the feed inlet. The pulse valve body includes an air blowing port, which is located on the side wall of the box and communicates with the inner cavity of the box. The air blowing port opens to one side.

[0014] In addition, a preferred structure is that a motor is installed on one side wall of the housing and at the bearing, and the output end of the motor is assembled and connected to the rotating shaft.

[0015] The beneficial effects of this utility model are as follows: This utility model sets a rotating sieve plate mechanism inside the box to sieve out impurities in rice. After the sieve plate mechanism rotates, the pulse valve body can blow down the impurities that are blocked on the screen and let them fall into the collection box from the waste outlet, ensuring that the screen will not be blocked and thus reducing the screening efficiency. In this way, the screening efficiency can be improved while ensuring that the screen will not be blocked and ensuring its service life. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figure 1-6 A screening device for primary processing of rice includes a placement platform 4, a box 1 on the upper surface of the placement platform 4, an inner cavity inside the box 1, an opening 17 in the middle of the inner cavity, bearings 18 symmetrically rotatably mounted on the two side walls of the box 1 at the opening 17, a screening plate mechanism 6 between the two bearings 18, the screening plate mechanism 6 rotating around the bearings 18 as the axis, the screening plate mechanism 6 located at the opening 17, the screening plate mechanism 6 includes a screening plate 63, a rotating shaft 61 mounted on one side of the screening plate 63, the two ends of the rotating shaft 61 being mounted on the inner ring of the bearings 18, and a baffle 62 fixedly connected to the other side of the rotating shaft 61 away from the screening plate 63, the baffle 62 facilitating the prevention of rice from splashing out from the opening 17.

[0025] The sieve plate 63 is provided with a screen 631, and an outlet 632 is provided on the other side of the screen 631 away from the rotating shaft 61, so that small stones can pass through the screen 631.

[0026] Furthermore, a first discharge port 11 is provided at the bottom of the box body 1 below the screening plate 63, and a feed port 14 is provided at the top of the box body 1 above the first discharge port 11, which facilitates the discharge of rice.

[0027] In addition, a second discharge port 41 is provided on the upper surface of the placement platform 4, and a first discharge port 11 is located above the second discharge port 41. A collection box 3 is placed on one side of the box body 1 on the upper surface of the placement platform 4. The collection box 3 is used to collect impurities that fall from the waste port 12.

[0028] Meanwhile, a waste outlet 12 is provided on one side of the box 1, which is located above the collection box 3. Viewing windows 13 are symmetrically provided on the side walls of both sides of the box 1, and the viewing windows 13 are used to observe the interior of the box 1.

[0029] In this case, a support plate 15 is vertically arranged on the bottom wall of the inner cavity of the box 1 on the side away from the first discharge port 11 and the opening 17. One end of the screening plate 63 abuts against the support plate 15. A discharge plate 16 is arranged on the other side of the support plate 15 away from the first discharge port 11. A discharge port 19 is opened on one side wall of the box 1 at the discharge plate 16. The discharge plate 16 is used to discharge the screened rice.

[0030] Meanwhile, a pulse valve body 5 is provided on one side wall of the housing 1 and on the side of the feed inlet 14. The pulse valve body 5 includes an air blowing port 51, which is located on the side wall of the housing 1 and communicates with the inner cavity of the housing 1. The air blowing port 51 faces the opening 17 on one side and is used to blow out compressed air from the pulse valve body 5.

[0031] In addition, a motor 2 is installed on one side wall of the housing 1 and at the bearing 18. The output end of the motor 2 is connected to the rotating shaft 61, and the motor 2 is used to rotate the rotating shaft 61.

[0032] In this embodiment, the operator pours rice into the feed inlet 14. The rice falls onto the sieve plate 63. Under the action of gravity, small impurities such as pebbles in the rice will pass through the sieve 631 and fall into the first discharge port 11, and be discharged from the second discharge port 41. The operator can collect the rice below the second discharge port 41. Rice that cannot pass through the sieve 631 will roll from the inclined sieve plate 63 onto the discharge plate 16 and be discharged from the discharge port 19.

[0033] After screening for a period of time, small impurities will clog the screen 631, requiring cleaning. At this time, the motor 2 drives the shaft 61 to rotate on the bearing 18, causing the screening plate 63 to rotate to the opening 17, while the baffle 62 rotates from the opening towards the waste port 12. At this time, the pulse valve body 5 sprays compressed air from the air blowing port 51, blowing the compressed air towards the screen 631, thereby blowing off the impurities clogging the screen 631 and letting them fall into the collection box 3 from the waste port 12, ensuring that the screening efficiency of the screen 631 will not be reduced due to clogging.

[0034] In this invention, a rotating sieving plate mechanism 6 is installed inside the housing 1. The sieving plate 63 is used to sieve out impurities from the rice. The pulse valve body 5, after the sieving plate mechanism 6 rotates, can blow off the impurities clogging the screen 631 and let them fall into the collection box 3 from the waste outlet 12. This ensures that the screen 631 will not be clogged, thus reducing the screening efficiency. In this way, the screening efficiency can be improved while ensuring that the screen 631 will not be clogged, thus ensuring its service life.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
