Description

Technical Field

[0001] This utility model relates to the field of feed grinding, and in particular to a convenient feed grinding device that is easy to clean and maintain. Background Technology

[0002] A feed grinding device is a mechanical device used to process pellet or block feed into fine particles. It uses high-speed rotating hammers, blades or grinding discs to strike, shear or grind the raw materials, thereby reducing the feed particle size, improving the digestibility and absorption rate, and facilitating subsequent processing steps such as mixing and pelleting.

[0003] When feed is pulverized, some raw materials, such as fibrous materials, are difficult to completely crush in conventional hammer mills or roller mills due to their high hardness or toughness. This results in the presence of large, substandard particles in the finished product, affecting the uniformity of the feed and the animal's feeding performance. At the same time, the pulverization of feed will generate extremely fine dust, which will adhere to the inner wall of the tank, making it very inconvenient to clean and remove. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a convenient feed grinding device that is easy to clean and maintain, thereby further improving the feed grinding effect and the ease of cleaning dust inside the device.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A convenient feed grinding device for easy cleaning and maintenance includes a grinding tank for support, a rotating rod rotatably connected to the middle of the grinding tank, a crushing roller blade fixedly connected to the outside of the rotating rod, a drive motor fixedly connected to the middle of the front end of the grinding tank, the drive end of the drive motor fixedly connected to the front end of the rotating rod, limiting frames fixedly connected to both sides of the inside of the grinding tank, a screening arc plate fixedly connected to the bottom of the limiting frames, a reverse rotation component installed inside the grinding tank to improve the feed grinding effect, a support frame fixedly connected to the upper rear end of the grinding tank, a rotating rod rotatably connected inside the support frame, a third bevel gear fixedly connected to the bottom end of the rotating rod, and an air intake and exhaust component installed on the rear side of the grinding tank to discharge residual feed to the outside.

[0008] Furthermore, a first bevel gear is fixedly connected to the outer rear side of the rotating rod, and a second bevel gear is fixedly connected to the outer side of the rear rotating sleeve. The first bevel gear meshes with the third bevel gear, and the second bevel gear meshes with the third bevel gear.

[0009] Furthermore, multiple support blocks are fixedly connected to the outer side of the limiting frame, and the outer sides of the support blocks are respectively fixedly connected to the inside of the crushing tank.

[0010] Furthermore, cleaning brushes are fixedly connected to the outer side of each actuating plate to clean feed debris from the inner side.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Reference Figures 1-3 This utility model provides an embodiment of a convenient feed grinding device that is easy to clean and maintain. It includes a grinding tank 1 for support, a rotating rod 17 rotatably connected to the middle of the grinding tank 1, a crushing roller blade 21 fixedly connected to the outside of the rotating rod 17, a drive motor 3 fixedly connected to the middle of the front end of the grinding tank 1, the drive end of the drive motor 3 fixedly connected to the front end of the rotating rod 17, a limiting frame 19 fixedly connected to both sides of the inside of the grinding tank 1, a screening arc plate 18 fixedly connected to the bottom of the limiting frame 19, a reverse rotation assembly installed inside the grinding tank 1 to improve the feed grinding effect, a support frame 11 fixedly connected to the upper rear end of the grinding tank 1, a rotating rod 10 rotatably connected inside the support frame 11, a third bevel gear 12 fixedly connected to the bottom end of the rotating rod 10, and an air intake and exhaust assembly installed on the rear side of the grinding tank 1 to discharge residual feed to the outside. The reverse rotation assembly includes rotating sleeves 8 located on both sides of the outside of the rotating rod 17, and multiple support rods 15 fixedly connected around the outer circumference of the rotating sleeves 8. (See reference...) Figure 4A toggle plate 16 is fixedly connected to the outer side of the support rod 15, and multiple auxiliary crushing blades 6 are fixedly connected to the inner side of the toggle plate 16. A first bevel gear 7 is fixedly connected to the outer rear side of the rotating rod 17, and a second bevel gear 9 is fixedly connected to the outer side of the rear rotating sleeve 8. The first bevel gear 7 meshes with the third bevel gear 12, and the second bevel gear 9 meshes with the third bevel gear 12. Multiple support blocks 20 are fixedly connected to the outer side of the limiting frame 19. The outer side of the support blocks 20 is fixedly connected to the inside of the crushing tank 1. Cleaning brushes 2 are fixedly connected to the outer side of the toggle plate 16 to clean the feed debris on the inner side. During operation, the raw material to be crushed is fed into the crushing tank 1 through the feeding frame at the top of the crushing tank 1. The crushing chamber, composed of the screening arc plate 18 and the limiting frame 19, limits the material. After the drive motor 3 starts, it drives the rotating rod 17 to rotate, causing the crushing roller blade 21 to rotate at high speed to carry out primary crushing. At the same time, the rotating rod 17 drives the rotating sleeve 8 to rotate through the meshing transmission of the first bevel gear 7 and the third bevel gear 12, which in turn drives the support rod 15 and the actuating plate 16 to make circular motion, continuously throwing the material in the limiting frame 19 up, so that it forms multiple collisions and crushing with the crushing roller blade 21. Moreover, the rotation direction of the rotating sleeve 8 is opposite to the rotation direction of the rotating rod 17, which assists the differential shearing between the crushing blade 6 and the crushing roller blade 21. The synergistic effect of the crushing blade 6 and the crushing roller blade 21 further enhances the crushing effect. Finally, the material that meets the particle size requirements falls and is discharged through the screen holes of the screening arc plate 18, realizing efficient and uniform crushing operation.

[0019] Reference Figure 1 , Figure 2 and Figure 3 The air intake and exhaust assembly includes a support circular frame 14 located at the top of the support frame 11. The inner side of the support circular frame 14 is fixedly connected to the rear end of the crushing tank 1. A vortex fan 13 is fixedly connected inside the support circular frame 14. Air intake pipes 4 are fixedly connected to both sides of the support circular frame 14. Air intake frames 5 are fixedly connected to both sides of the crushing tank 1. The front ends of the air intake pipes 4 are respectively fixedly connected to the rear side of the air intake frames 5. Traction plates 23 are fixedly connected to the lower outer side of the limiting frame 19 to achieve the flow of the exhaust air against the inner wall of the crushing tank 1. A partition plate 22 is fixedly connected to the middle of the bottom end of the screening arc plate 18. The outer side of the partition plate 22 is fixedly connected to the lower inner side of the crushing tank 1. After the feed is crushed, the dust particles generated pass through the screening arc plate 18 and adhere to the inner wall of the crushing tank 1. At this time, the dust on the inner wall of the limiting frame 19 is effectively removed by the rotating cleaning brush 2. After the system starts the vortex fan 13, the external air is introduced into the air intake frame 5 through the air intake pipe 4 and enters the inside of the crushing tank 1. Due to the obstruction effect of the limiting frame 19, the airflow flows downward along the annular channel formed by the limiting frame 19 and the tank. When the airflow passes through the specially designed traction plate 23, it is compressed and accelerated, forming a wall-adhering airflow and a tornado-like dust-cleaning flow field, which powerfully blows the dust attached to the inner wall downward, ultimately achieving efficient self-cleaning inside the tank. This design significantly improves the convenience and thoroughness of dust cleaning and ensures the continuous and stable operation of the equipment.

[0020] Working principle: The raw material to be crushed is fed into the crushing tank 1 through the feeding frame at the top of the crushing tank 1. The feed is confined inside by the screening arc plate 18 and the limiting frame 19. At this time, the drive motor 3 is started to rotate the rotating rod 17, thereby rotating the crushing roller blade 21 to crush the feed. As the rotating rod 17 rotates, the first bevel gear 7 rotates. The first bevel gear 7 meshes with the third bevel gear 12, thereby rotating the third bevel gear 12. The third bevel gear 12 meshes with the second bevel gear 9, thereby rotating the rotating sleeve 8. The rotation of the rotating sleeve 8 drives the support rod 15 to rotate, thereby driving the actuating plate 16 to rotate, throwing the feed inside the limiting frame 19 up, so that it comes into contact with the outside of the crushing roller blade 21 again, and assisting the crushing blade 6 and the crushing roller blade 21 to cooperate with each other to crush the feed. The feed is discharged downward through the holes of the screening arc plate 18, thereby further improving the feed crushing effect. After the feed is crushed, the generated dust will pass through the screening arc plate 18 and come into contact with the inner wall of the crushing tank 1. The dust inside the limiting frame 19 will be cleaned out by the rotation of the cleaning brush 2. At this time, the vortex fan 13 is started to draw the external air into the air inlet pipe 4 and transmit it to the inside of the crushing tank 1 through the air inlet frame 5. Because of the obstruction of the limiting frame 19, the air flows downward around the gap created between the limiting frame 19 and the crushing tank 1. When the air comes into contact with the traction plate 23, the incoming air is further compressed, so that it adheres to the inner wall of the crushing tank 1, forming a tornado-like dust cleaning flow field, blowing the dust adhering to the inner wall downward, thereby completing the cleaning of the internal dust and improving the convenience of dust cleaning inside the device.

[0021] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
