Description

Technical Field

[0001] This utility model relates to the field of rotary grading screen technology, specifically a rotary grading screen. Background Technology

[0002] In the production processes of many industries such as grain, feed, flour, chemicals, and food, materials need to be graded and screened to ensure product quality and the smooth progress of subsequent production processes. For example, in grain processing, impurities in the grain raw materials need to be screened out; in feed processing, feed needs to be screened according to different outer diameters to ensure the consistency of the size specifications of the finished feed particles. With the continuous expansion of industrial production scale and the increasing requirements for product quality, the demand for efficient and accurate grading and screening equipment is becoming more and more urgent.

[0003] Rotary grading screens are commonly used for screening. However, large pieces of material can easily clog the screen's mesh, affecting the screening process and causing inconvenience.

[0004] In view of this, we propose a rotary grading screen. Utility Model Content

[0005] The purpose of this invention is to provide a rotary grading screen to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A rotary grading screen includes a support frame, with multiple support rings fixedly connected to the inner wall of the support frame, and a rotating ring rotatably connected to the inner wall of the support rings. A grading screen is fixedly connected to the side wall of the rotating ring, and a drive motor is fixedly mounted on the surface of the support frame. A rotating rod is fixedly connected to the output end of the drive motor, and a connecting rod is fixedly connected to the side wall of the rotating rod. One end of the connecting rod is fixedly connected to the inner wall of the rotating ring. The support frame has an outlet and an inlet inside, and multiple cleaning grooves are provided on the side wall of the support frame. A cleaning plate is slidably connected to the inner wall of the cleaning groove, and a cleaning brush is fixedly connected to the side wall of the cleaning plate. One end of the cleaning brush abuts against the side wall of the grading screen, and an adjustment device is provided on one side of the cleaning plate. A filter device is provided inside the inlet.

[0008] First, the material is placed into the feed inlet. The filter device will then filter out any stones in the material to prevent them from scratching the grading screen. Next, the drive motor is started, which drives the rotating rod to rotate. The rotating rod, through the connecting rod, drives the rotating ring to rotate, causing the grading screen to rotate and perform the material screening. While the grading screen is rotating, the cleaning plate pushes the cleaning brush against the side wall of the grading screen, thereby brushing away any material clogging the screen mesh. This prevents clogging from affecting the screening operation of the grading screen and improves ease of use.

[0009] Preferably, the adjusting device includes a rotating bolt rotatably connected to the side wall of the support frame, and an adjusting plate is threadedly connected to the side wall of the rotating bolt, and the side wall of the adjusting plate is fixedly connected to the side wall of the cleaning plate.

[0010] Depending on the usage requirements, the rotating bolt can be rotated to move it closer to or away from the cleaning plate or support frame. In turn, the cleaning plate will move the cleaning brush closer to or away from the grading screen. The tightness can be adjusted to facilitate the cleaning of the grading screen by the cleaning brush and improve the ease of use.

[0011] Preferably, the filtration device includes a placement groove opened inside the feed inlet, and a filter ring is slidably connected to the inner wall of the placement groove, and a filter screen is fixedly connected to the inner wall of the filter ring.

[0012] After the material is fed into the feed inlet, large stones in the material will be filtered by the filter screen in the filter ring, preventing these stones from entering the grading screen and scratching it, thereby extending the service life of the grading screen and improving the safety of use.

[0013] Preferably, a strip plate is fixedly connected to the side wall of the rotating bolt;

[0014] By setting up a strip plate, holding the strip plate can help rotate the rotating bolt, making it easy to adjust the tightness of the cleaning brush and improving ease of use.

[0015] Preferably, a limiting plate is fixedly connected to the side wall of the filter ring;

[0016] By setting a limiting plate, the limiting plate will abut against the surface of the support frame after the filter ring slides into the placement groove, thereby completing the limiting work of the filter ring and preventing the filter ring from moving at will.

[0017] Preferably, the surface of the support frame is provided with a pin groove, and a pin rod is slidably connected to the inner wall of the pin groove, with the top end of the pin rod being fixedly connected to the bottom surface of the limiting plate.

[0018] By setting up a locking pin and a locking pin groove, the locking pin and the locking pin groove can provide a certain limiting and fixing effect after the filter ring slides into the placement groove, thereby improving the stability of the filter ring when it is filtering.

[0019] Preferably, a pull handle is fixedly connected to the side wall of the filter ring;

[0020] By installing a handle, pulling the handle can help move the filter ring, making it easier to replace and repair the filter ring and the placement slot, thus improving ease of use.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] 1. This rotary grading screen first places the material into the feed inlet. At this time, the filter device filters out stones in the material to prevent them from scratching the grading screen. Then, the drive motor is started, which drives the rotating rod to rotate. The rotating rod drives the rotating ring to rotate through the connecting rod, so that the grading screen rotates to perform the grading work. When the grading screen rotates, the cleaning plate pushes the cleaning brush against the side wall of the grading screen, thereby brushing away the material blocking the mesh of the grading screen, preventing the blocking material from affecting the grading work of the grading screen, and improving the convenience of use.

[0023] 2. This rotary grading screen can be rotated according to usage requirements, which will cause the rotating bolt to move closer to or away from the cleaning plate and support frame. Subsequently, the cleaning plate will cause the cleaning brush to move closer to or away from the grading screen, adjusting the tightness to facilitate the cleaning of the grading screen by the cleaning brush and improve the ease of use.

[0024] 3. This rotary grading screen, when the material is fed into the feed inlet, will filter out large stones in the material by the filter screen in the filter ring, preventing these stones from entering the grading screen and scratching it, thereby extending the service life of the grading screen and improving the safety of use.
