Abstract
Description
Technical Field
[0001] This utility model relates to the field of screening machine technology, and more specifically, to an impurity separation type stirring screening machine. Background Technology
[0002] In the fields of grain, edible fungi, Chinese herbal medicine and legume cultivation, the post-harvest material processing stage is crucial. Taking grain cultivation as an example, whether it is wheat, corn or rice, the harvested grain is often mixed with a large number of impurities, such as straw fragments, sand and gravel, shriveled grains, etc. These impurities not only affect the storage and transportation of grain and reduce the quality of grain, but may also damage machinery and equipment in subsequent processing.
[0003] Existing material screening equipment mostly adopts a simple vibrating screen structure. However, during use, materials tend to accumulate and clump together, resulting in low screening efficiency. When processing large quantities of materials, traditional equipment requires frequent manual intervention, such as manually cleaning the screen and turning the material. This not only increases labor intensity but also easily affects screening quality due to untimely human operation. Therefore, an impurity separation type stirring screen is proposed.

Rotation of the screen barrel can drive the first and second scrapers to rotate and scrape off impurities attached to the inner wall of the barrel body, facilitating material discharge. A discharge pipe is fixedly connected to the center of the bottom of the screen barrel, through which the raw material in the middle of the screen barrel can be discharged. A limiting ring is fixedly sleeved in the middle of the discharge pipe, and a toothed ring is fixedly sleeved at the top of the screen barrel. The limiting ring limits the discharge pipe, thereby limiting the screen barrel, and the toothed ring facilitates drive transmission.

A second motor is fixedly connected to one side of the top of the barrel. A gear is fixedly connected to the output end of the second motor.

The stabilizing ring improves the stability of the top of the screen barrel. The stirring mechanism can stir the raw materials inside the screen barrel, improving screening efficiency and quality.
[0007] The top of the barrel is fixedly connected to a feed inlet, and a stabilizing annular groove is provided at the bottom of the feed inlet. A discharge outlet is fixedly connected to the bottom of one side of the barrel. A limiting tube is fixedly connected to the bottom of the barrel, and a limiting groove is provided in the middle of the limiting tube.

[0010] Preferably, the feed pipe extends into the interior of the limiting pipe, the limiting ring is adapted to the limiting groove, and the limiting ring is located in the middle of the limiting groove to improve the stability of the bottom of the screen barrel.
[0011] Preferably, the stabilizing ring corresponds to the stabilizing ring groove, the stabilizing ring is located in the middle of the stabilizing ring groove, and the bottom of the barrel is fixedly connected with a support leg to improve the stability of the top of the screen barrel.
[0012] Preferably, the stirring mechanism includes a support rod fixed at the top opening of the sieve barrel, a first motor fixedly connected to the top of the support rod, a rotating rod connected to the output end of the first motor, and a spiral blade fixedly connected to the bottom end of the rotating rod.
[0013] Preferably, a stirring frame is fixedly connected to the outside of the rotating rod, and a stirring rod is fixedly connected to the middle of the stirring frame. The wall of the stirring frame is in contact with the wall of the sieve barrel. The side walls and bottom walls of the sieve barrel are provided with sieve holes.

[0014] The technical effects and advantages of this utility model are as follows:
[0015] 1. This utility model firstly sets up a system where materials are poured into the inside of a screen barrel. By starting a second motor and controlling the gears, the screen barrel rotates, causing the raw materials in the middle of the screen barrel to rotate and stir, generating centrifugal force to achieve the screening function. At the same time as screening, the first motor is started to control the spiral blades and stirring frame to rotate and stir the internal raw materials, achieving simultaneous screening and stirring. This avoids agglomerates affecting the screening quality. Furthermore, the rotation of the stirring frame can scrape the inner wall of the screen barrel, preventing blockage of the screen holes on the screen barrel surface. This reduces the workload while improving the screening quality and efficiency.
[0016] 2. This utility model also features a first scraper and a second scraper that can scrape off impurities from the inner wall of the screen barrel when they separate from the inside of the barrel and adhere to it. These impurities fall to the bottom of the inner cavity of the barrel and are easily discharged through the outlet. The stability of the top of the screen barrel is improved by the cooperation of the stabilizing ring and the stabilizing ring groove. The stability of the bottom of the screen barrel is improved by the cooperation of the feeding pipe and the limiting ring with the limiting pipe and the limiting groove. This also improves the stability of the screen barrel rotation and enhances the overall performance.
[0017] In summary, through the interaction of the above-mentioned multiple functions, stirring can be achieved during screening, avoiding clumping that could affect screening quality, while also preventing clogging of the screen holes on the screen barrel surface, thus reducing workload while improving screening quality and efficiency.
