[0002] Pig feed is a feedable substance formulated according to the nutritional needs of animals. It includes categories such as protein feed, energy feed, roughage, green fodder, silage, mineral feed, and feed additives. According to nutritional composition, it is divided into complete feed, concentrate feed, and premix feed. During the production and processing of pig feed, screening devices are used to screen the raw materials of pig feed.

[0003] In existing technologies, feed ingredients often contain trace amounts of moisture, oil, or are inherently sticky, making it easy for them to adhere and accumulate on the screen surface. This makes it impossible to grade and screen the impurities in the ingredients, affecting the processing quality of the ingredients. At the same time, it is not convenient to coordinate with dust removal devices during screening, resulting in dust raised during the screening process causing the dust concentration in the workshop to exceed the standard. Summary of the Invention

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0017] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0018] Example 1: As Figure 1 - Figure 4As shown, this utility model provides a raw material screening and dust removal device for pig feed production, including a support frame 1, an outer shell 3 installed inside the support frame 1, a screening mechanism 8 installed inside the outer shell 3, the screening mechanism 8 including a first filter screen 82 and a second filter screen 83, one end of the first filter screen 82 is fixedly connected to one end of the second filter screen 83, the side of the first filter screen 82 and the side of the second filter screen 83 are fixedly connected to the inner side of the outer shell 3, a scraping mechanism 2 is installed above the second filter screen 83, a telescopic rod 88 is fixedly connected to the bottom side of the first filter screen 82, a connecting frame 81 is fixedly connected to one end of the telescopic rod 88, a compression spring 89 is sleeved on the outside of the telescopic rod 88, the compression spring 89 is installed between the first filter screen 82 and the connecting frame 81, a connecting rod 87 is rotatably connected to one side of the connecting frame 81, and the outer shell 3... A dust removal mechanism 5 is installed on one side of the housing 3. The dust removal mechanism 5 includes a dust pump 53. One side of the dust pump 53 is fixedly connected to the outside of the housing 3. One end of the dust pump 53 is fixedly connected to a three-way dust suction pipe 52. The other two ends of the three-way dust suction pipe 52 are fixedly connected to dust suction hoods 51. The two dust suction hoods 51 are fixedly connected to the two sides of the housing 3 respectively. The other end of the dust pump 53 is connected to a dust collection system for unified dust collection. A second motor 810 is fixedly connected to one side of the housing 3. A second belt assembly 84 is installed at the output end of the second motor 810. A rotating rod 85 is installed at one end of the second belt assembly 84. The other end of the rotating rod 85 passes through one side of the housing 3. A rotating disk 86 is fixedly connected to the other end of the rotating disk 86. One side of the rotating disk 86 is rotatably connected to the other end of the connecting rod 87.

[0019] The second motor 810 is started, driving the second belt assembly 84 to rotate, which in turn drives the rotating rod 85 to rotate. The rotating rod 85 drives the rotating disk 86 to rotate. The connecting rod 87 is eccentrically connected to one side of the rotating disk 86. The rotating disk 86 pushes the connecting rod 87 to reciprocate. The connecting rod 87 drives the connecting frame 81 to move back and forth. The connecting frame 81 causes the first filter screen 82 to vibrate back and forth through the telescopic rod 88 and the compression spring 89. The compression spring 89 acts as a buffer and reset, and the telescopic rod 88 ensures vibration stability. After the raw material enters from the top of the outer shell 3, small-diameter particles pass through the first filter screen 82 and the second filter screen 83 under the screening of the first filter screen 82 and the second filter screen 83. The remaining impurities move along the filter screen in the designated direction. At the same time, during the material feeding process, the dust pump 53 is started. The dust pump 53 draws dust-laden air from the two dust hoods 51 through the three-way dust suction pipe 52, collects and treats the dust, removes the dust in the screening process, and improves the production environment.

[0020] Example 2: Figure 1 and Figure 3As shown, the scraping mechanism 2 includes a first scraping roller 22 and a second scraping roller 23. One end of the first scraping roller 22 and one end of the second scraping roller 23 are rotatably connected to the inner side of the outer shell 3. The other end of the first scraping roller 22 and the other end of the second scraping roller 23 penetrate the side wall of the outer shell 3. The other end of the first scraping roller 22 and the other end of the second scraping roller 23 are connected to a first belt assembly 24. The other end of the first scraping roller 22 is fixedly connected to a first motor 21. One side of the first motor 21 is fixedly connected to the outer side of the outer shell 3. A baffle is fixedly connected inside the outer shell 3. The baffle is inclined and set below the first scraping roller 22. A conveyor belt 7 is installed on the bottom side of the support frame 1. The conveyor belt 7 is set below the opening at the bottom of the outer shell 3. A first discharge port 4 is opened on one side of the outer shell 3, and a second discharge port 6 is opened on the other side of the outer shell 3.

[0021] The first motor 21 is started, which drives the first scraping roller 22 to rotate. The first scraping roller 22 drives the second scraping roller 23 to rotate synchronously through the first belt assembly 24. After the raw material enters the outer shell 3, it is scraped by the rotation of the first scraping roller 22 and the second scraping roller 23. The lumpy material is broken up and the large impurities are initially separated. The material is evenly dispersed to the subsequent screening area. After scraping and screening, the large particles of the material are discharged from the first discharge port 4 and the second discharge port 6. The qualified material passes through the screen and falls onto the conveyor belt 7, which is then transported to the next process. The inclined baffle inside the outer shell 3 guides the flow of the material and avoids accumulation.

[0022] The operation and working principle of this device are as follows: First, start the first motor 21 to drive the first scraping roller 22 to rotate, and the second scraping roller 23 to rotate synchronously to scrape and disperse the raw materials. The dust removal mechanism 5 starts synchronously, and the dust pump 53 continuously extracts the dust-laden air generated inside the outer shell 3 through the two dust hoods 51 connected by the three-way dust suction pipe 52, forming a multi-directional dust suction channel to capture and collect the dust raised during the screening process. The evenly dispersed raw materials flow to the screening mechanism 8 below. The second motor 810 works to drive the rotating rod 85 and the rotating disk 86 fixed at one end to rotate synchronously, pushing the connecting frame 81 to reciprocate. Under the buffering and reset action of the compression spring 89, the first filter screen 82 and the second filter screen 83 vibrate to classify and screen the dispersed raw materials. Large-diameter impurities move to both sides along the filter screen and are discharged from the first discharge port 4 and the second discharge port 6 respectively. The raw materials fall onto the conveyor belt 7 and are automatically transported to the next production process by the conveyor belt 7.

[0023] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
