The hollow ring is fixedly connected to the inner wall of the feeding box. The temperature sensor is fixedly connected to the right side of the bottom of the feeding box. The through groove is located on the left side of the bottom of the feeding box. This invention achieves automatic control of rice feeding, preventing rice from falling directly from the feeding box into the main body before it is fully cooled, and speeds up the cooling process of the rice, thus improving the efficiency of rice dust removal and cooling.

[0003] In the aforementioned prior art, a feeding box is used to store rice, and the rice can be stirred by controlling the rotation of a lever. In conjunction with a blower, airflow is blown into the rice to achieve the cooling operation. However, since the rice is stored in the feeding box for cooling, if too much is piled up, the blown airflow may not be able to penetrate the entire rice pile evenly, resulting in insufficient cooling of the rice inside and affecting the cooling efficiency. Furthermore, it is not convenient to separate dust or small broken rice from the rice. Therefore, a rice grading sieve dust removal and cooling control device is needed to meet people's needs.

Detailed Implementation

[0020] 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.

[0021] Example 1: Please refer to Figure 1-4 This utility model provides a technical solution: a rice grading sieve dust removal and cooling control device, including a support frame 100; two mounting frames 200 are symmetrically installed above the support frame 100, and the same feeding structure is installed on the two mounting frames 200; a sieving structure is installed inside the support frame 100; a cooling structure is installed on the support frame 100, and the cooling structure is located above the sieving structure; a turntable 500 is installed on the feeding structure, and a swinging structure is installed on the turntable 500. In use, rice can be placed in the feeding structure, and the rice can continuously fall onto the sieving structure through the operation of the feeding structure. The rice is sieved using the sieving structure, and during the process, the cooling structure can separate dust or small broken rice from the rice while cooling the rice. The swinging structure can disperse the rice as it falls into the sieving structure.

[0022] Furthermore, the feeding structure includes a hopper 201, which is installed between two mounting brackets 200. A discharge pipe 202 is installed on the hopper 201, and a connecting sleeve 203 is rotatably sleeved on the discharge pipe 202. A guide plate 204 is installed on the connecting sleeve 203, and the guide plate 204 is connected to the connecting sleeve 203. Rice can be stored in the hopper 201. When the rice is discharged, it can fall onto the guide plate 204 through the discharge pipe 202 and the connecting sleeve 203, and then slide down the inclined surface of the guide plate 204.

[0023] Furthermore, a fixed frame 205 is installed above the hopper 201, and an auxiliary motor 206 is installed above the fixed frame 205. The output end of the auxiliary motor 206 passes through the fixed frame 205 and is connected to a connecting shaft 207. A spiral feeding blade 208 is fixedly sleeved on the connecting shaft 207. The spiral feeding blade 208 contacts the inner wall of the discharge pipe 202. By turning on the auxiliary motor 206, the connecting shaft 207 is driven to rotate. The rotating connecting shaft 207 can drive the spiral feeding blade 208 to rotate inside the discharge pipe 202. When the spiral feeding blade 208 rotates, it can continuously convey the material in the hopper 201 out of the discharge pipe 202.

[0024] Furthermore, the screening structure includes two screen plates 300, both of which are located inside the support frame 100 and below the guide plate 204. A vibration motor 301 is installed below each of the two screen plates 300. The falling rice will fall onto the screen plate 300. By turning on the vibration motor 301, the corresponding screen plate 300 can be driven to vibrate, promoting the vibration of the rice on it and causing it to slide down. By setting two sets of screen plates 300 with different mesh sizes, broken rice and rice can be screened.

[0025] Furthermore, the cooling structure includes multiple cooling fans 400, which are installed on one side of the support frame 100. Air ducts 401 are installed at the air blowing ends of the cooling fans 400, and the air ducts 401 are installed inside the support frame 100. The air outlets of the air ducts 401 face the screen plate 300. A guide tube 402 is installed inside the support frame 100, and multiple dust removal fans 403 are installed on one side of the guide tube 402. The air blowing ends of the dust removal fans 403 are connected to the guide tube 402, and the air outlets of the guide tube 402 are located below the material guide plate 204. The support frame 100 has a removable recycling bin 404 installed inside. As the rice slides down, the dust removal fan 403 can be turned on to blow air into the guide tube 402. Under the guidance of the guide tube 402, the airflow can pass under the guide plate 204. As the rice falls from the guide plate 204, the airflow can blow away the dust or small broken rice in the rice and blow it into the recycling bin 404 for collection. When the rice is being sieved, the cooling fan 400 can be turned on to blow air into the rice on the sieve plate 300 through the air duct 401 to cool the rice.

[0026] Example 2: As Figure 3-4 To ensure the rice is dispersed onto the sieve plate 300, a swing structure is arranged on the turntable 500. This swing structure includes a linkage shaft 501, which is installed below the turntable 500. The turntable 500 is mounted on one end of the connecting shaft 207. A linkage rod 502 is installed on the guide plate 204. A linkage sliding hole 503 is provided inside the linkage rod 502, and the linkage shaft 501 is movably installed within the linkage sliding hole 503. An annular limiting groove 5 is provided inside the connecting sleeve 203. 04. A limiting ring 505 is rotatably installed in the annular limiting groove 504. The limiting ring 505 is fixedly sleeved on the discharge pipe 202. Under the continuous rotation of the connecting shaft 207, it can drive the turntable 500 to rotate. The rotating turntable 500 can drive the linkage rod 502 to swing back and forth through the cooperation of the linkage shaft 501 and the linkage sliding hole 503, thereby driving the guide plate 204 to swing back and forth. Under the continuous swing of the guide plate 204, the position of the rice falling can be changed. The other features are the same as in Example 1.

[0027] The working principle is as follows: Rice can be stored in the hopper 201. By turning on the auxiliary motor 206, the connecting shaft 207 rotates. The rotating connecting shaft 207 drives the spiral feeder 208 to rotate inside the discharge pipe 202. When the spiral feeder 208 rotates, it continuously conveys the material in the hopper 201 out of the discharge pipe 202, causing the rice to fall onto the guide plate 204 through the connecting sleeve 203. The rice then slides continuously down the inclined surface of the guide plate 204. During this process... Turn on the dust removal fan 403 to blow air towards the guide tube 402. Guided by the guide tube 402, the airflow passes under the material guide plate 204. As the rice falls from the material guide plate 204, the airflow blows away dust or small broken rice particles, which are then blown into the collection box 404 for collection. The continuously falling rice will land on the sieve plate 300. By turning on the vibration motor 301, the corresponding sieve plate 300 will vibrate, promoting the vibration of the rice on it and causing it to slide down. Two sets of sieve plates 300 with different mesh sizes can be used to sieve broken rice and regular rice. Simultaneously, a cooling fan 400 can be turned on, blowing air onto the rice on the sieve plates 300 through the air duct 401 to cool the rice. Furthermore, the continuous rotation of the connecting shaft 207 drives the turntable 500 to rotate. The rotating turntable 500 drives the linkage shaft 501 to rotate in a circular motion. The rotating linkage shaft 501 moves within the linkage sliding hole 503, causing the linkage shaft 501 to drive the linkage through the linkage sliding hole 503. The rod 502 swings back and forth, which in turn causes the linkage rod 502 to drive the guide plate 204 to swing back and forth. When the guide plate 204 swings, it can drive the connecting sleeve 203 to rotate, so that the connecting sleeve 203 rotates on the limiting ring 505 through the annular limiting groove 504. This allows the connecting sleeve 203 and the guide plate 204 to achieve the effect of rotation. Under the continuous swing of the guide plate 204, the position of the rice falling can be changed, so that the rice can fall evenly onto the sieve plate 300, which is beneficial for subsequent cooling.
