[0004] The existing filtering mechanism for rice processing mentioned above realizes efficient filtration of rice through two steps of air screening and mesh screening.

The impurities separated in the two steps cannot be effectively collected, which is not conducive to the subsequent centralized treatment of impurities. Therefore, it is urgent to propose a corresponding high-efficiency filtering mechanism for rice processing to solve the above problems. Utility Model Content

[0008] Preferably, the blowing assembly includes a fan fixedly connected to the outer wall of the wind screen bin, and the output end of the fan is connected to multiple groups of air outlets in parallel, and the multiple groups of air outlets are connected to the interior of the wind screen bin.

[0009] Preferably, a plurality of groups of cross-distributed guide plates are fixedly connected to the inner surface wall of the air screen bin, and the plurality of groups of air outlets are staggered with the plurality of groups of guide plates.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0014] 1. In the present application, rice is introduced from the top of the wind screen bin. When the rice falls into the introduction section, the fan output end provides horizontal airflow for the rice through multiple groups of air outlets. Lighter impurities are separated into the guide bin, and then the impurities fall and are transferred to the bottom of the outer bin through a conduit. The driving member drives the spiral rod to rotate, and the spiral rod stirs and pushes the rice that falls into the discharge section. When the rice passes through the mesh drum, the remaining impurities inside the rice will fall to the bottom of the outer bin through the mesh holes on the mesh drum until the rice is discharged through the rice outlet. In this way, efficient filtration of the rice is achieved while centralized collection of impurities is achieved, which facilitates subsequent centralized treatment of impurities, thereby improving the convenience of using the high-efficiency filtration mechanism for rice processing.

In the present application, multiple groups of staggered guide plates are fixed inside the wind screen bin, and multiple groups of air outlets are staggered and distributed between the multiple groups of guide plates, thereby delaying the falling time of the rice while ensuring the time for the airflow to contact the rice material. At the same time, the collision between the rice material and the guide plates can effectively avoid the condensation of impurities and rice material, further ensuring the filtering effect of the rice material.

[0024] A high-efficiency filtering mechanism for rice processing includes a conveying assembly 1, which includes a fixedly connected inlet section 101, a mesh drum 102, a discharge section 103, and a pushing portion for pushing rice. An outer bin 2 is fixedly connected between the discharge section 103 and the inlet section 101. An impurity outlet 4 and a rice outlet 3 are respectively provided at the bottom of the outer bin 2 and the discharge section 103. A wind screen bin 5 is fixedly connected to the top of the outer bin 2. A material guide bin 6 is fixedly connected to the outer wall of the wind screen bin 5. The material guide bin 6 is connected to the interior of the outer bin 2 through a conduit 10. A blowing assembly for providing a wind source is provided on the outer wall of the wind screen bin 5.

[0025] The rice material is introduced from the top of the wind screen bin 5. In the process of the rice material falling into the introduction section 101, the output end of the fan 7 provides a horizontal airflow for the rice material through multiple groups of air outlets 8. The lighter impurities will be separated into the guide bin 6. Then the impurities fall and are transferred to the bottom of the outer bin 2 through the conduit 10. The driving member 12 drives the screw rod 13 to rotate. The screw rod 13 stirs and pushes the rice material falling into the introduction section 101. When the rice material passes through the mesh cylinder 102, the remaining impurities inside the rice material will fall to the bottom of the outer bin 2 through the mesh holes on the mesh cylinder 102 until the rice material is discharged through the rice material outlet 3. In this way, the rice material is efficiently filtered and the impurities are collected in a centralized manner, which facilitates the subsequent centralized treatment of the impurities, thereby improving the convenience of using the high-efficiency filtering mechanism for rice processing.

[0026] Specifically, such as Figure 2 and Figure 4 As shown, the blowing component includes a fan 7 fixedly connected to the outer wall of the wind screen bin 5, and a plurality of groups of air outlets 8 are connected in parallel at the output end of the fan 7, and the plurality of groups of air outlets 8 are connected to the inside of the wind screen bin 5. The output end of the fan 7 provides horizontal airflow for the rice material through the plurality of groups of air outlets 8, and the inner surface wall of the wind screen bin 5 is fixedly connected to a plurality of groups of cross-distributed guide plates 11, and the plurality of groups of air outlets 8 are staggered with the plurality of groups of guide plates 11. A plurality of groups of staggered guide plates 11 are fixed inside the wind screen bin 5, and the plurality of groups of air outlets 8 are staggered between the plurality of groups of guide plates 11, thereby delaying the falling time of rice and ensuring the time for the airflow to contact the rice material. At the same time, the collision between the rice material and the guide plate 11 can effectively avoid the condensation of impurities and rice material, further ensuring the filtering effect of the rice material.

[0027] Specifically, such as Figure 2 and Figure 3 As shown, the top of the outer bin 2 is fixedly connected to a support plate 14 through a connecting frame 9, and the connecting frame 9 and the support plate 14 are respectively fixedly connected to the wind screen bin 5 and the fan 7, so as to ensure the stability of the wind screen bin 5, the outer bin 2 and the fan 7. The horizontal end of the connecting frame 9 is fixedly connected to the top of the outer bin 2 through a locking rod 15, so as to ensure the convenience of disassembly and assembly of the connecting frame 9. The pushing part includes a driving member 12 fixedly connected to the outer wall of the unloading section 103, and the output end of the driving member 12 is fixedly connected to a screw rod 13, which stirs and pushes the rice material falling into the inlet section 101.

[0028] Working principle: Rice is introduced from the top of the wind screen bin 5. When the rice falls into the inlet section 101, the output end of the fan 7 provides horizontal airflow for the rice through multiple sets of air outlets 8. Lighter impurities will be separated into the inside of the guide bin 6. Then the impurities fall and are transferred to the bottom of the outer bin 2 through the conduit 10. The driving member 12 drives the screw rod 13 to rotate. The screw rod 13 stirs and pushes the rice that falls into the inlet section 101. When the rice passes through the mesh cylinder 102, the remaining impurities inside the rice will fall to the bottom of the outer bin 2 through the mesh holes on the mesh cylinder 102 until the rice passes through. The rice material outlet 3 is derived, thereby achieving efficient filtration of the rice material and centralized collection of impurities, which facilitates subsequent centralized treatment of impurities, thereby improving the convenience of using the efficient filtration mechanism for rice processing. Multiple groups of staggered guide plates 11 are fixed inside the wind screen bin 5, and multiple groups of air outlets 8 are staggered and distributed between the multiple groups of guide plates 11, thereby delaying the falling time of rice and ensuring the time for the airflow to contact the rice material. At the same time, the collision between the rice material and the guide plate 11 can effectively avoid the condensation of impurities and rice material, further ensuring the filtering effect of the rice material.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
