Description
Technical Field
[0001] The utility model belongs to the technical field of rice processing, and in particular relates to a grading and screening device for rice processing. Background Art
[0002] Screening is a method of separating particles according to their size, specific gravity, charge, magnetism and other powder properties. Screening is the process of using a perforated sieve to separate mixed materials of different particle sizes into various particle size grades.
[0003] Generally, when rice is graded and screened, multiple driving mechanisms are often required to drive each level of the screen to perform screening movement. Such different degrees of screening of the screens make it difficult for the upper and lower levels of the screens to be aligned, which in turn causes the screened grains to fall out easily, resulting in food waste. In addition, the graded screening of multiple driving mechanisms is often costly. Therefore, a graded screening device for rice processing is needed to solve the above problems. Utility Model Content
[0004] The purpose of the utility model is to provide a grading and screening device for rice processing to solve the problems raised in the above-mentioned background technology.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a grading and screening device for rice processing, comprising a machine platform, a plurality of support rods are fixedly connected to the machine platform, the top ends of the plurality of support rods are commonly fixedly connected to a top platform, the top platform is obliquely arranged, a displacement groove is penetrated inside the top platform, a screen frame is slidably connected to the inside of the displacement groove through a first slide bar, a first screen is placed inside the screen frame, the first screen is slidably connected to the screen frame through a second slide bar, an electromagnetic block is fixedly connected to the second slide bar, and the lower surface of the electromagnetic block is magnetically attracted to the screen frame. The top of the second slide bar is fixedly connected with a first handle, the lower surface of the screen frame is connected with a connecting frame, a second screen is obliquely inserted inside the connecting frame, the second screen is fixedly provided with a second handle at the insertion position on the back of the connecting frame, the back of the second screen is fixedly connected with a magnetic plate, the magnetic plate is magnetically attracted to the back of the connecting frame, the front and back of the screen frame are fixedly connected with connecting blocks, one side of the two connecting blocks are fixedly connected with an electric telescopic rod, one end of the two electric telescopic rods are fixedly connected with a fixed block, and the two fixed blocks are fixedly connected to the top platform.
[0006] By arranging an electric telescopic rod, the screen frame is driven to reciprocate and telescopically screen in the displacement groove through the connecting block under the telescopic power of the electric telescopic rod, so that the material screened by the first screen in the screen frame will further fall onto the second screen in the connecting frame for the next level of screening. During this period, since the screen frame and the connecting frame are connected as one, the second screen in the connecting frame will also be screened synchronously, and at the same time, all the screened materials in the screen frame will be received, and there will be no shaking off, thereby preventing the material from shaking off. In addition, the second screen can be pulled out of the connecting frame by pulling the second handle. When the magnetic attraction of the electromagnetic block is released, the first handle can be held to take out the first screen in the screen frame through the second slide bar to facilitate its replacement. The screening of the first screen and the second screen are driven jointly by the electric telescopic rod, which saves a certain cost compared with the traditional multi-drive mechanism.
[0007] As a preferred implementation, a first blanking frame is fixedly connected to the interior of the machine platform, and a plurality of supporting legs are fixedly connected to the lower surface of the machine platform.
[0008] As a preferred embodiment, a discharge door is rotatably provided on one side of the connection frame.
[0009] As a preferred embodiment, a motor is provided at the rotating part of the discharge door.

During this period, due to the guiding effect of the guide plate, the materials can be easily stored in the second discharge frame.
[0012] As a preferred implementation, a second blanking frame is fixedly connected to one side of the machine platform, and the guide plate is located above the second blanking frame.
[0013] Compared with the prior art, the beneficial effects of the utility model are:
[0014] The utility model provides an electric telescopic rod, and under the telescopic power of the electric telescopic rod, the connecting block drives the screen frame to perform reciprocating telescopic screening in the displacement groove, so that the material screened by the first screen in the screen frame will further fall onto the second screen in the connecting frame for the next level of screening.

In addition, the second screen can be pulled out of the connecting frame by pulling the second handle. When the magnetic attraction of the electromagnetic block is released, the first handle can be held to take out the first screen in the screen frame through the second slide bar to facilitate its replacement. The screening of the first screen and the second screen are driven jointly by the electric telescopic rod, which saves a certain cost compared with the traditional multi-drive mechanism.

The second screen 10 is fixedly provided with a second handle bar 11 at the insertion position on the back side of the connecting frame 9. A magnetic plate 12 is fixedly connected to the back side of the second screen 10. The magnetic plate 12 is magnetically attracted to the back side of the connecting frame 9.

One end of the two electric telescopic rods 14 is fixedly connected to a fixed block 15. The two fixed blocks 15 are fixedly connected to the top platform 3.
[0024] By setting an electric telescopic rod 14, the screen frame 4 is driven to reciprocate and telescopically screen in the displacement slot 23 through the connecting block 13 under the telescopic power of the electric telescopic rod 14, so that the material screened by the first screen 6 in the screen frame 4 will further fall into the second screen 10 in the connecting frame 9 for the next level of screening. During this period, since the screen frame 4 is connected to the connecting frame 9 as a whole, the second screen 10 in the connecting frame 9 will also be screened synchronously, and at the same time, all the screened materials in the screen frame 4 will be taken over without shaking off, thereby preventing the material from shaking off.
