Description

Technical Field

[0001] This utility model relates to the field of rice processing, and in particular to a rice grain grading device for rice processing. Background Technology

[0002] Before processing rice, it is necessary to grade the rice grains to meet different processing scenarios. When grading rice grains, rice grains are usually placed on multi-level screens and vibrated. Rice grains of different sizes will be screened to achieve the purpose of rapid screening.

[0003] Existing rice grain grading devices are not suitable for repeatedly vibrating the mesh frame when grading and screening rice grains. This results in incomplete screening of the rice grains by the mesh frame, and the rice grains may contain moisture, causing them to stick together. Furthermore, existing rice grain grading devices are not suitable for dispersing and combing the rice grains, resulting in insufficient screening of the rice grains and thus poor grading effect. Utility Model Content

[0004] To overcome the above-mentioned shortcomings, this utility model provides a rice grain grading device for rice processing, which can repeatedly vibrate the mesh frame to make the rice grain screening more thorough, and can disperse and comb the rice grains to make the rice grain screening more complete, thereby enhancing the grading effect.

[0005] The technical solution of this utility model is: a rice grain grading device for rice processing, including a grading box, two support frames fixedly connected to the grading box, an inclined plate slidably connected to the grading box, three mesh frames slidably connected to the grading box, two first screens, a second screen and a third screen respectively provided on the three mesh frames, three discharge hoppers fixedly connected to the grading box, a vibration component for accelerating grading provided in the grading box, a combing component for dispersing rice provided on the inclined plate, and a material control component for controlling the amount of material discharged on the grading box.

[0006] Furthermore, the collection groove of the wire frame has an inclined structure.

[0007] Furthermore, the vibration assembly includes a motor, which is fixedly connected to one side of the grading box. A transmission rod is fixedly connected to the output shaft of the motor, and the transmission rod is rotatably connected to the grading box. Two cams are fixedly connected to the transmission rod, and connecting plates are fixedly connected between the two sides of the three mesh frames. Both connecting plates are slidably connected to the grading box.

[0008] Furthermore, the combing assembly includes a fixing plate, two fixing plates are fixedly connected to the bottom side of the inclined plate, and wheels are rotatably connected to the bottom of both fixing plates. A horizontal plate is fixedly connected to the inner wall of the grading box, and two compression springs are connected between the horizontal plate and the inclined plate. Several spacers are fixedly connected to the two inclined surfaces of the inclined plate.

[0009] Further, the material control assembly comprises a sliding block which is slidingly connected to the inner wall of the grading box, and the bottom of the sliding block is fixedly connected with two protruding rods.

[0010] The beneficial effects are: 1. The cam rotates repeatedly to press the connecting plate, so that the screen frame moves up and down repeatedly, the screen frame moves up and down repeatedly to generate vibration, the screen frame vibration accelerates the screening of rice, and the grading is faster, thereby improving the efficiency of grading.

[0011] 2. The screen frame moves up and down repeatedly to press the wheel repeatedly, so that the sliding block moves up and down repeatedly, the sliding block moves up and down intermittently to block the discharge port, thereby preventing too many rice from being discharged and accumulated on the screen, thereby avoiding that too many rice affects the quality of screening, thereby enhancing the effect of grading, the screen frame moves up and down repeatedly to press the inclined plate, and the inclined plate moves up and down under the action of the compression spring, the inclined plate moves up and down to make the rice fall on the inclined plate, the inclined plate moves up and down to disperse and comb the falling rice through the partition plate, thereby preventing the rice from sticking together and slowing down the falling speed of the rice, thereby avoiding that the rice is not fully screened, thereby further enhancing the effect of grading.
