AI Technical Summary
The traditional rice screening machine uses wind blowing methods, which consumes time and effort, and the screening effect is poor, resulting in the frequent occurrence of husks and cortexes in the rice, which reduces the screening effect.
A rice screening machine is designed, using a motor to drive the threaded rod, so that the sliding block moves in the groove, drives the scraper to push the rice for screening, and collects the screened rice into the box through the screening hole.
The efficiency and effectiveness of rice screening are improved, ensuring that the rice in each location can be effectively screened, and the screened rice is entered into the collection box through the screening hole for easy collection and processing.

Technical Field
[0001] The utility model relates to the technical field of rice processing, in particular to a rice screening machine. Background Technique
[0002] Rice processing refers to the process of removing the husk (glume) and cortex (bran layer) of rice grains and finally making rice with better edible quality. Rice grains consist of husk, cortex, embryo and endosperm. The purpose of rice processing is to separate the endosperm from other parts with the least degree of breakage and make rice with better edible quality, that is, the process of removing the husk and cortex from the cleaned rice grains.
[0003] When using rice for processing and screening, the traditional rice screening is generally carried out by the method of blowing. Such an effect is time-consuming and laborious, and the screening effect of the device is not very good, resulting in the situation that the husk and cortex of some of the rice screened by the device are together, thus reducing the screening effect of the device on rice.

[0019] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention will be further described below with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.
[0020] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the present invention is not limited by the specific embodiments disclosed in the following specification.
[0021] Please refer to Figures 1-5 , the present invention provides a technical solution: a rice screening machine, including a screening box 1. Grooves 4 are opened at the edges near the front and rear sides of the top of the screening box 1. A buffer block 2 is fixedly connected to the outer surface of one side of the screening box 1 near the edge of one side. Through the fixation of the buffer block 2, the vibration of the motor 3 can be reduced during use. A motor 3 is fixedly installed on the top of the buffer block 2. The output shaft of the motor 3 is fixedly welded with a threaded rod 5, and one end of the threaded rod 5 extends between the inner walls of one side of the groove 4 and is rotatably connected through a bearing. The motor 3 drives the threaded rod 5 to rotate inside the groove 4. Sliding blocks 6 are slidably connected inside both grooves 4, and one of the sliding blocks 6 is threadedly sleeved with the threaded rod 5. Connecting blocks 7 are fixedly arranged on the tops of the two sliding blocks 6. A scraper 8 is fixedly connected between the outer surfaces of the opposite sides of the two connecting blocks 7, and the bottom of the scraper 8 is in fit connection with the inner top surface of the screening box 1. The sliding block 6 will drive the connecting block 7 to move, and the connecting block 7 drives the scraper 8 to push inside the screening box 1, so as to push and screen the rice inside.
[0022] A plurality of screening holes 9 are arranged at equal intervals in the horizontal direction on the inner top surface of the screening box 1. The screened rice will enter the collection box 12 through the screening holes 9.
[0023] Support plates 10 are fixedly connected to the front, rear and outer surfaces of the screening box 1 near the edges on both sides. Fixed bases 11 are fixedly connected to the bottoms of the four support plates 10. Through the fixation of the support plates 10, the device is convenient for stable use. Through the fixation of the fixed bases 11, the device is more stable.
[0024] A collection box 12 is fixedly connected between the outer surfaces on the opposite sides of the four support plates 10, and the collection box 12 is located directly below the screening box 1. One side outer surface of the collection box 12 is fixedly communicated with a discharging mechanism 13. A clamping groove 14 is formed at the edge near one side on the front side outer surface of the discharging mechanism 13. A clamping block 15 is clamped and connected inside the clamping groove 14. Fixed blocks 16 are fixedly connected to the edges near the top and bottom of the front side outer surface of the clamping block 15. A pull ring 17 is fixedly connected between the front side outer surfaces of the two fixed blocks 16. By pulling the pull ring 17, the pull ring 17 will drive the fixed block 16 to move, so that the clamping block 15 moves inside the clamping groove 14 to open, and then the rice in the collection box 12 flows out. The amount of movement is used to control the size of the release, so that the rice is conveniently and effectively collected.
[0025] Working principle: When the device is in use, first pour the rice to be screened into the inside of the screening box 1. Then, by starting the motor 3, the motor 3 drives the threaded rod 5 to rotate inside the groove 4, so that the sliding block 6 moves inside the groove 4. By rotating forward and backward, the forward or backward movement of the sliding block 6 is adjusted. At the same time, the sliding block 6 drives the connecting block 7 to move, and the connecting block 7 drives the scraping plate 8 to push inside the screening box 1, so that the rice inside is pushed and screened, thereby improving the screening effect of the device and enabling the rice at each position to be effectively screened. The screened rice will enter the collection box 12 through the screening holes 9 and be collected at the collection box 12. When it needs to be opened, by pulling the pull ring 17, the pull ring 17 drives the fixed block 16 to move, so that the clamping block 15 moves inside the clamping groove 14 to open, and then the rice in the collection box 12 flows out. The amount of movement is used to control the size of the release, so that the rice is conveniently and effectively collected, improving the use effect of the device.
