DETAILED DESCRIPTION

[0018] like Figure 1 and Figure 2 As shown, a screening machine for rice processing includes a chassis 101, and base brackets are installed on both sides of the chassis 101 to support the device. A material inlet 102 is fixedly installed on one side of the chassis 101, and a finished product outlet 104 is fixedly installed at one end of the chassis 101 close to the ground. A defective product outlet 105 is also fixedly installed at one end of the chassis 101, and the defective product outlet 105 is fixedly connected to the finished product outlet 104. The device sends materials into the device from the material inlet 102, and after the parts in the chassis 101 are processed, the materials are classified and flow out of the device from the finished product outlet 104 and the defective product outlet 105. A dust outlet is provided on the end of the chassis 101 close to the material inlet 102, and a fan 106 is provided in the dust outlet to take the dust and rising debris in the chassis 101 out of the device.

[0019] like Figures 2 to 4 As shown, an angle motor 103 is fixedly mounted on the outer wall of the chassis 101, a main shaft 201 is fixedly mounted on the output shaft of the angle motor 103, a plurality of main shaft rings 202 are fixedly mounted on the main shaft 201, a shock absorber 203 is rotatably mounted on the main shaft ring 202, and a limiting plate 211 is also fixedly mounted on the main shaft ring 202, the limiting plate 211 is used to limit the rotation direction of the shock absorber 203, so that the shock absorber 203 can only rotate in Figure 2The damper 203 rotates counterclockwise in the middle, and the inner arc plate 204 is fixedly installed on the movable end, and the outer arc plate 205 is slidably installed on the inner arc plate 204. The inner arc plate 204 is provided with a screening hole, and the outer arc plate 205 is provided with a closed hole. The screening hole has the same diameter as the closed hole. Both sides of the inner arc plate 204 are in close contact with the inner wall of the chassis 101, and both sides of the outer arc plate 205 are in close contact with the inner wall of the chassis 101. The outer arc plate 205 is fixedly installed with a leak-proof bracket 209 at one end away from the material inlet 102, and a protruding frame 210 is provided on the other end of the outer arc plate 205 away from the leak-proof bracket 209. The protruding frame 210 is in contact with the inner wall of the chassis 101 in the initial state, and the main shaft 20 When the inner arc plate 204 rotates counterclockwise, the shock absorber 203 can drive the inner arc plate 204 to rotate counterclockwise around the axis of the main shaft 201. After the inner arc plate 204 rotates for a certain distance, the end of the inner arc plate 204 close to the leak-proof bracket 209 will contact the leak-proof bracket 209. In this state, the inner arc plate 204 and the outer arc plate 205 form a closed surface. Then, the inner arc plate 204 drives the outer arc plate 205 and the leak-proof bracket 209 to rotate together. The purpose is to allow the materials in the inner arc plate 204 and the outer arc plate 205 to start falling out from the shock absorber 203 after the inner arc plate 204 and the outer arc plate 205 rotate forty-five degrees, until the logistics are dumped after the inner arc plate 204 and the outer arc plate 205 rotate ninety degrees.

[0020] like Figures 2 to 4 As shown, the defective product outlet 105 is arranged at one end in the chassis 101 and is fixedly installed with a fixed bracket 208, the fixed bracket 208 is fixedly connected to the inner wall of the chassis 101, a plurality of arc plate springs 207 are fixedly installed on the fixed bracket 208, and a closed arc plate 206 is fixedly installed on the other end of the arc plate spring 207, the closed arc plate 206 is slidably connected to the inner wall of the chassis 101, the closed arc plate 206 is slidably connected to the finished product outlet 104, the closed arc plate 206 completely closes the finished product outlet 104 in the initial state, and the closed arc plate 206 can also completely close the defective product outlet 105 after sliding, the closed arc The end of plate 206 away from the arc plate spring 207 can contact the protruding frame 210. After the protruding frame 210 moves a certain distance, it can contact the closed arc plate 206. Then the outer arc plate 205 will drive the closed arc plate 206 to slide in the chassis 101, allowing the closed arc plate 206 to gradually open the closed finished product outlet 104, and the closed arc plate 206 will gradually close the connection between the defective product outlet 105 and the inside of the chassis 101 during the movement. When the outer arc plate 205 rotates ninety degrees around the axis of the main shaft 201, the closed arc plate 206 will completely break away from the contact with the finished product outlet 104, and the closed arc plate 206 will completely close the defective product outlet 105.

[0021] like Figure 2As shown, a shaking motor 107 is fixedly mounted on the outer wall of the chassis 101, and a cam 108 is fixedly mounted on the output shaft of the shaking motor 107. A shaking plate 109 is also slidably mounted on the side of the chassis 101 on which the shaking motor 107 is arranged, and the cam 108 is in contact with the shaking plate 109, and the shaking plate 109 is in contact with the outer arc plate 205. A shaking spring 110 is fixedly mounted on the cam 108, and the other end of the shaking spring 110 is fixedly mounted on the inner wall of the chassis 101. When the shaking plate 109 slides on the chassis 101, it can drive the outer arc plate 205 to swing together, and the shock absorber 203 will contract during the swinging process of the outer arc plate 205, so that the outer arc plate 205 can produce a vibration effect, thereby accelerating the screening process of the materials in the inner arc plate 204.

[0022] Working principle: This device pours unhulled rice into the chassis 101 from the material inlet 102, and then the fan 106 can be started to allow the fan 106 to take the dust and debris in the chassis 101 that can be driven by the airflow out of the chassis 101. When the rice gradually enters the outer arc plate 205 and fills the arc surface of the outer arc plate 205, the feeding can be stopped, and then the shaking motor 107 can be started for screening. After the shaking motor 107 is started, the cam 108 rotates, and the cam 108 will drive the shaking plate 109 to slide on the chassis 101, and the shaking plate 109 will drive the outer arc plate 205 to shake, so that the rice in the outer arc plate 205 can be screened, and the rice that is smaller than the screening hole and the closed hole will fall into the defective product outlet 105, so that the defective rice can be screened out, and after the defective product screening is completed, the angle motor 103 can be started to allow the angle motor 103 to drive the main shaft 201 to Figure 2 The inner arc plate 204 rotates counterclockwise, so that the inner arc plate 204 closes the outer arc plate 205 and drives the outer arc plate 205 to rotate together. The rotation of the outer arc plate 205 drives the closed arc plate 206 to slide on the finished product outlet 104, allowing the closed arc plate 206 to open the finished product outlet 104, and allowing the closed arc plate 206 to close the defective product outlet 105, thus completing the switching of the outlets. During the rotation of the inner arc plate 204 and the outer arc plate 205, the rice on the outer arc plate 205 will fall into the finished product outlet 104 from the end of the outer arc plate 205 where the protruding frame 210 is provided.
