[0001] This utility model relates to the field of rice processing technology, and in particular to a rice processing device with a screening function. Background Technology

[0002] Rice is a finished product made from paddy through cleaning, hulling, milling, and finishing processes. The process of removing various impurities mixed in with paddy through appropriate technological processes and proper operating methods to ensure the quality of rice is an essential part of rice processing. Rice screening is an indispensable step in the rice processing process.

[0003] Traditional rice processing equipment is prone to clogging of the sieve cylinder during the screening process, which affects the screening effect and requires disassembly and maintenance of the sieve cylinder. The existing sieve cylinder fixing method is relatively complicated, making disassembly difficult and requiring specific tools. This not only increases the labor intensity of the operator but also affects the processing efficiency of the equipment. Summary of the Invention

[0015] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0016] Reference Figures 1-5 As shown, this utility model provides a technical solution: a rice processing device with screening function, including a base plate 1, two support plates 2 installed on the top of the base plate 1, a drive motor 3 installed on the side of one of the support plates 2, and a shaft rotatably connected inside the other support plate 2. The output end of the drive motor 3 passes through the support plate 2 and is provided with a motor shaft 4. A fixing frame 5 is fixed to one end of the motor shaft 4 and the shaft body. A guide frame 6 is provided on the top of the fixing frame 5. A sieve cylinder 7 is installed on the opposite side of the fixing frame 5. The sieve cylinder 7 is located inside the guide frame 6. Two first housings 8 are fixed to both ends of the sieve cylinder 7. Second housings 9 are fixed to both sides of the fixing frame 5. A knob 10 is threadedly connected to the side wall of the second housing 9. A limit block 11 is fixed to one end of the knob 10 inside the second housing 9. Two moving plates 12 are slidably connected inside the second housing 9. The two moving plates 12 are located on both sides of the limit block 11. A locking block 13 is fixed to one end of the moving plate 12. A locking block 13 is provided at both ends of the first housing 8 to cooperate with the locking block 13. The groove 14 has two fixing holes 15 at one end of the top of the base plate 1. The support plate 2 is inserted into the fixing holes 15 through its own insertion hole by a pin. Through the structure of the fixing holes 15, the fixing frame 5, the first housing 8, the second housing 9, the knob 10, the limiting block 11, the moving plate 12, the locking block 13, and the locking groove 14, in use, rice is first put into the sieve cylinder 7, then the support plate 2 is moved so that the sieve cylinder 7 is connected to the fixing frame 5, and then the pin is inserted into the fixing hole 15 through the support plate 2 to provide stable support. In the first step, during docking, the movable plate 12 and the locking block 13 are inserted into the first housing 8. During use, by turning the knob 10, the limiting block 11 fixed to it is rotated and squeezed, so that the movable plate 12 pushes the locking block 13 into the slot 14, so that the fixed frame 5 and the screen cylinder 7 are firmly connected. Conversely, the two can be quickly separated so that the screen cylinder 7 can be cleaned and maintained after disassembly, so as to avoid the mesh on the screen cylinder 7 from being blocked and affecting the screening effect. The operation process is simple and convenient and does not require specific tools.

[0017] Reference Figure 4 As shown in this embodiment: Springs 16 are fixed on both sides inside the second housing 9. The other end of the springs 16 is fixed to the moving plate 12. Through the structure of the springs 16, when it is necessary to separate the fixing frame 5 and the screen cylinder 7, the limit block 11 is rotated and moved away from the moving plate 12 by turning the knob 10 in the opposite direction. At this time, the moving plate 12 will be pushed by the rebound force of the springs 16, which will cause the locking block 13 to disengage from the inside of the locking groove 14, thereby releasing the fixing of the screen cylinder 7. Then the user only needs to pull out the pin, move the support plate 2, and remove the screen cylinder 7.

[0018] Reference Figure 4As shown in this embodiment, the limiting block 11 is elliptical in shape. With the elliptical design of the limiting block 11, the elliptical limiting block 11 can more evenly squeeze the moving plates 12 on both sides during use, ensuring that the card block 13 is firmly inserted into the card slot 14. At the same time, the elliptical structure can also provide a smoother transition during rotation, reduce wear, and extend service life.

[0019] Reference Figure 4 As shown in this embodiment: Limiting rods 17 are fixed on both sides inside the second housing 9, and through holes 18 are provided on the surface of the moving plate 12 to cooperate with the limiting rods 17. Through the structure of the limiting rods 17 and the through holes 18, the movement of the moving plate 12 can be guided, ensuring the stability of the moving plate 12 during the movement process and avoiding deviation or shaking.

[0020] Reference Figure 4 As shown in this embodiment, the surface of the knob 10 is provided with multiple strip grooves arranged in a circle. These strip grooves make it easier to hold and rotate the knob 10, increasing the comfort and convenience of operation. At the same time, the design of the strip grooves can also increase the friction of the knob 10 surface, preventing slippage during rotation and ensuring the accuracy of operation.

[0021] Reference Figures 3-4 As shown in this embodiment: both ends of the screen cylinder 7 are fixed with sealing gaskets 19, and the fixing frame 5 has a sealing groove 20 on the side near the screen cylinder 7 that works with the sealing gaskets 19. Through the structure of the sealing gaskets 19 and the sealing groove 20, the installation position of the screen cylinder 7 can be further limited, the stability of the connection between the screen cylinder 7 and the fixing frame 5 can be improved, and at the same time, it can also provide stable support during disassembly.

[0022] Reference Figure 1 and Figure 5 As shown in this embodiment: a collection box 21 is provided at the bottom of the guide frame 6, and sliders 22 are fixed at both ends of the bottom of the collection box 21. Slide grooves 23 that cooperate with the sliders 22 are provided at both ends of the top of the base plate 1. Through the structure of the collection box 21, sliders 22 and slide grooves 23, the screened rice can be collected. At the same time, it is also convenient to transfer and process the collected rice, thereby improving the overall processing efficiency.

[0023] Working principle: The user utilizes the structure of the fixing hole 15, fixing frame 5, first housing 8, second housing 9, knob 10, limiting block 11, moving plate 12, locking block 13, and locking groove 14. During use, first, rice is placed into the sieve cylinder 7. Then, the support plate 2 is moved to align the sieve cylinder 7 with the fixing frame 5. Next, a pin is inserted through the support plate 2 into the fixing hole 15 to provide stable support. Further, during alignment, the moving plate 12 and locking block 13 are inserted into the first housing 8. During use, turning the knob 10 rotates the limiting block 11, which is fixed to it. The moving plate 12 is squeezed, causing it to push the card block 13 into the slot 14, thus securing the fixed frame 5 and the screen cylinder 7. Conversely, the two can be quickly separated to facilitate cleaning and maintenance of the screen cylinder 7 after disassembly, preventing the mesh on the screen cylinder 7 from becoming clogged and affecting the screening effect. The operation is simple and convenient, requiring no special tools. At the same time, the structure of the collection box 21, slider 22, and chute 23 allows for the collection of screened rice, and also facilitates the transfer and processing of the collected rice, improving the overall processing efficiency.
