Description

Technical Field

[0001] This utility model relates to the field of automatic rice grading machines, specifically a multi-screen type automatic rice grading machine. Background Technology

[0002] Rice, also known as paddy rice, is one of the main sources of human food. After production, rice needs to be separated from broken grains and screened, which requires the use of screening equipment.

[0003] Currently, after rice is milled and hulled, it may contain some broken rice and impurities. Most existing methods separate the rice from the broken rice by setting a filter plate at the rice outlet. However, the filtered broken rice and impurities are collected together, which does not separate the broken rice from the impurities. Therefore, a multi-screen type automatic rice grading machine is designed. Utility Model Content

[0004] In order to solve the above problems, the purpose of this utility model is to provide a multi-screen type automatic rice grading machine to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model proposes a multi-screen type automatic rice grading machine, including a support frame, a screening box on the top of the support frame, and a feed hopper fixedly installed on the top of the screening box;

[0006] The top of the support frame is equipped with a screening mechanism, which includes a motor, a rotating shaft, a rotating plate, a fixed shaft, a horizontal plate, a fixed rod, and a fixed plate. A motor is fixedly installed on one side of the top of the support frame. A rotating shaft that passes through and extends into the support frame is fixedly installed on the output shaft of the motor. A rotating plate is fixedly installed at the bottom end of the rotating shaft. A fixed shaft is fixedly installed at the bottom of the rotating plate. A horizontal plate is rotatably connected to the bottom end of the fixed shaft. A fixed rod is fixedly installed on one side of the top of the horizontal plate. A fixed plate that is fixed to the screening box is fixedly installed at the top end of the fixed rod.

[0007] In one example, a plurality of screening screens are slidably connected to one side of the screening box, and a handle is fixedly installed on one side of the front of each of the screening screens.

[0008] In one example, a discharge hopper is fixedly installed on one side and the back side of a plurality of the screening boxes, and the plurality of discharge hoppers are fixed to the screening boxes by bolts.

[0009] In one example, four mounting plates are fixedly mounted on the top of the support frame, and a support rod is rotatably connected to the top of each of the four mounting plates.

[0010] In one example, the top ends of the four support rods are rotatably connected to support plates, and the top ends of the four support plates are rotatably connected to mounting rods.

[0011] In one example, the tops of the four mounting rods are fixedly connected to the four corners of the bottom of the screening box.

[0012] The multi-screen automatic rice grading machine proposed in this utility model can bring the following beneficial effects:

[0013] 1. This multi-screen type automatic rice grading machine uses the movement of a horizontal plate in the sieving mechanism to drive the movement of a fixed rod, which in turn causes the sieving box to shake, thus causing the sieving mesh box inside to shake and automatically sieving the rice in the sieving box. It can sieving rice and distinguish broken rice and mixed rice after sieving for classified collection.

[0014] 2. This multi-screen type automatic rice grading machine can sieve the rice by shaking the screening box, which in turn drives the screening mesh box to shake. The sieved rice is discharged through the discharge hopper. When the screening box shakes, the mounting rod drives the support plate to move and rotate around the support rod, thereby limiting and stabilizing the shaking. Attached Figure Description

[0021] To more clearly illustrate the overall concept of this utility model, a detailed description will be provided below with reference to the accompanying drawings.

[0022] like Figures 1-4As shown, an embodiment of this utility model proposes a multi-screen type automatic rice grading machine, including a support frame 1, a screening box 8 on the top of the support frame 1, and a feed hopper 9 fixedly installed on the top of the screening box 8.

[0023] The top of the support frame 1 is equipped with a screening mechanism, which includes a motor 2, a rotating shaft 3, a rotating plate 4, a fixed shaft 5, a horizontal plate 6, a fixed rod 7, and a fixed plate 15. The motor 2 is fixedly installed on one side of the top of the support frame 1. The output shaft of the motor 2 is fixedly installed with a rotating shaft 3 that passes through and extends into the support frame 1. The bottom end of the rotating shaft 3 is fixedly installed with a rotating plate 4. The bottom of the rotating plate 4 is fixedly installed with a fixed shaft 5. The bottom end of the fixed shaft 5 is rotatably connected to the horizontal plate 6. The top side of the horizontal plate 6 is fixedly installed with a fixed rod 7. The top end of the fixed rod 7 is fixedly installed with a fixed plate 15 that is fixed to the screening box 8.

[0024] Specifically, a plurality of screening boxes 10 are slidably connected to one side of the screening box 8. Each screening box 10 has a handle 17 fixedly installed on one side of its front. The rice is screened through the screening boxes 10. The aperture of the screening boxes 10 decreases in sequence. The screening box 8 fixes the screening boxes 10.

[0025] Specifically, a discharge hopper 16 is fixedly installed on one side and the back side of multiple screening boxes 10. The multiple discharge hoppers 16 are fixed to the screening boxes 10 by bolts, and the screened rice is discharged through the discharge hoppers 16.

[0026] Specifically, four mounting plates 13 are fixedly installed on the top of the support frame 1, and support rods 14 are rotatably connected to the top of each of the four mounting plates 13. The support rods 14 are fixed by the mounting plates 13, and the support rods 14 are fixed to the support plate 12.

[0027] Specifically, the top of each of the four support rods 14 is rotatably connected to a support plate 12, and the top of each of the four support plates 12 is rotatably connected to an installation rod 11. The installation rod 11 is fixed by the support plate 12, and the installation rod 11 provides fixed support for the screening box 8.

[0028] Specifically, the tops of the four mounting rods 11 are fixedly connected to the four corners of the bottom of the screening box 8, and the rice is screened through the screening box 8.

[0029] Working principle: Rice is fed into the screening box 8 through the feed hopper 9. Then, the motor 2 is started to drive the rotating shaft 3 to rotate, which in turn drives the rotating plate 4 to rotate. This causes the fixed shaft 5 to rotate, which in turn drives the horizontal plate 6 to move. This, in turn, drives the fixed plate 15 to move through the fixed rod 7, which in turn causes the screening box 8 to shake. This causes the screening screen box 10 to shake, thus screening the rice. The screened rice is discharged through the discharge hopper 16. When the screening box 8 shakes, the mounting rod 11 drives the support plate 12 to move and rotate around the support rod 14, thereby limiting and stabilizing the shaking.
