Description

Technical Field

[0001] This utility model relates to the field of livestock feed processing technology, specifically a grain crushing roller for shredding. Background Technology

[0002] The grain crushing roller is mainly installed in the crusher. It is used to tear, crush, and pulverize feed ingredients such as silage corn, sorghum stalks, and hay, changing the physical form of the feed ingredients to make them finer and more uniform, thereby improving subsequent utilization efficiency. The longer the feed fiber, the more it can stimulate rumination in dairy cows. During rumination, dairy cows produce saliva, which can buffer the rumen pH value and keep the rumen healthy. Moreover, the higher the effective fiber content of the feed, the better it is for stabilizing and improving the milk fat percentage.

[0003] When existing shredding grain crushing rollers are in operation, there is usually a gap between the end face and the inner wall of the machine. The presence of this gap can easily cause some fibers to get stuck. After a period of time, the fibers stuck in the gap are prone to corrosion. Corroded fibers can easily come into contact with the fibers that are subsequently shredded and crushed, thus causing contamination. If there is no gap, the shredding grain crushing roller will rub against the inner wall of the machine with each rotation, which will generate more noise and wear. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a grain crushing roller for crushing shredded grains, so as to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a grain crushing roller for crushing shredded grains, comprising a roller body, a support connected inside the roller body, and ribs connected to the outer surface of the support, with through holes on both sides of the ribs; a first retaining ring and a second retaining ring are respectively connected inside the support, and a first skeleton is provided inside the first retaining ring, and a second skeleton is provided inside the second retaining ring.

[0006] By adopting the above technical solution, the installation operation can be completed by pressing the bracket into the end face of the roller body. The bracket and roller body are assembled with an interference fit, ensuring stable installation and preventing structural detachment. Furthermore, the ribs increase the structural strength of the bracket and prevent deformation of the bracket towards the inner ring, thus avoiding affecting the limiting position of the interference fit. When disassembly is required, the worker only needs to pass the hook through the through hole, and then apply force to the bracket using the hook to pull it out. During use, the first retaining ring can block the gap between the roller body end face and the inner wall of the machine, thereby preventing material from entering. The first retaining ring is trumpet-shaped and made of fluororubber material, possessing good elasticity and wear resistance. It has anti-aging properties, can adapt to gaps of different widths and is suitable for high temperature and high speed environments, extending the service life of the structure. At the same time, the first retaining ring is reinforced by the first skeleton to avoid the expansion, twisting and plastic deformation of the first retaining ring caused by the centrifugal force of rotation, ensuring structural stability for long-term use. The second retaining ring works on the same principle as the first retaining ring, and the second skeleton works on the same principle as the first skeleton. The main function of the second retaining ring and the second skeleton is to prevent material from entering the roller body after the exposed first retaining ring is damaged. The material is blocked by the support and the second retaining ring. Compared with cleaning the long inside of the roller body, cleaning the outer support and the second retaining ring is simpler and more convenient.

[0007] Furthermore, the bracket is interference-fitted with the roller body, and multiple ribs and through holes are provided.

[0008] By adopting the above technical solution, the staff can complete the installation operation by pressing the bracket into the end face of the roller. The bracket and the roller are assembled with an interference fit, which ensures stable installation and prevents the structure from falling off. In addition, the rib plate increases the structural strength of the bracket and prevents the bracket from deforming inward and affecting the limit of the interference fit. When disassembly is required, the staff only needs to pass the hook through the through hole, and then the staff can apply force to the bracket with the hook to pull it out.

[0009] Furthermore, both the first and second frames are made of spring steel.

[0010] By adopting the above technical solution, the first retaining ring is reinforced by the first skeleton, which avoids the expansion, twisting and plastic deformation of the first retaining ring caused by the centrifugal force of rotation, thus ensuring structural stability for long-term use. The second skeleton is based on the same principle as the first skeleton.

[0011] Furthermore, both the first and second retaining rings are made of aramid short fiber reinforced fluororubber or polyester TPU.

[0012] By adopting the above technical solution, the first retaining ring is horn-shaped and made of fluororubber material, which has good elasticity, wear resistance and aging resistance. It can adapt to different widths of gaps and is suitable for high temperature and high speed environments, thus extending the service life of the structure. The principle of the second retaining ring is the same as that of the first retaining ring.

[0013] Furthermore, the first retaining ring is trumpet-shaped, and one end of the second retaining ring is bent outward.

[0014] By adopting the above technical solution, the shape of the first retaining ring can be adapted to gaps of different widths, and the shape of the second retaining ring can fit the shaft.

[0015] Furthermore, the first retaining ring is fixedly connected to the first frame, and the second retaining ring is fixedly connected to the second frame.

[0016] By adopting the above technical solution, if the first retaining ring and the second retaining ring are made of fluororubber material, the first skeleton and the second skeleton are placed in a mold, and the fluororubber raw material is placed on the surface of the first skeleton and the second skeleton by compression molding or injection molding. After the fluororubber raw material cools and solidifies, the first retaining ring with the built-in first skeleton and the second retaining ring with the built-in second skeleton are obtained. If the first retaining ring and the second retaining ring are made of TPU material, the first skeleton and the second skeleton are placed in a mold and the processing of the first retaining ring and the second retaining ring is completed by injection molding.

[0017] Furthermore, the roller body is made of alloy tool steel and its surface is chrome-plated.

[0018] By adopting the above technical solution, alloy tool steel forged blanks are selected for the processing of the roller body. Then, the inner and outer circles of the blank are rough machined by CNC machine tool, and the inner and outer rings and the spiral grooves of the outer ring are precision machined. Finally, the blank is quenched to obtain the roller body. After the roller body is formed, the inner circle is precision machined again. The high-precision inner circle facilitates the subsequent installation of bearings and brackets. After the inner circle is precision machined for the second time, the roller body can be electroplated to form a hard chrome electroplated layer on the surface of the roller body.

[0019] Furthermore, the outer ring of the roller is evenly distributed with multiple serrations.

[0020] By adopting the above technical solution, after the inner and outer circles and the outer spiral groove are processed, the blank is milled to form the saw teeth, which facilitates the roller to crush and shred the feed raw materials.

[0021] Furthermore, the inner ring of the bracket is penetrated by a first bolt, and the first retaining ring is detachably connected to the bracket via the first bolt.

[0022] By adopting the above technical solution, the staff puts the first retaining ring into the bracket, and then limits the first retaining ring by screwing in the first bolt, thus completing the installation operation. If the first retaining ring is damaged in the future, the first bolt can be removed to stop limiting the first retaining ring, making it easy to replace the first retaining ring.

[0023] Furthermore, a second bolt penetrates the outer surface of the bracket, and the second retaining ring is detachably connected to the bracket via the second bolt.

[0024] By adopting the above technical solution, the staff put the second retaining ring into the bracket, and then tightened the second bolt to limit the second retaining ring, thus completing the installation operation. If the second retaining ring is damaged in the future, the second bolt can be removed to stop limiting the second retaining ring, which facilitates the replacement of the second retaining ring.

[0025] In summary, the present invention has the following main advantages:

[0026] 1. This utility model, through the setting of a first retaining ring and a first skeleton, enables the first retaining ring to block the gap between the roller end face and the inner wall of the machine, thereby preventing material from entering. The first retaining ring is trumpet-shaped and made of fluororubber material, which has good elasticity, wear resistance and aging resistance. It can adapt to gaps of different widths and is suitable for high temperature and high speed environments, extending the service life of the structure. At the same time, the first skeleton reinforces the first retaining ring, preventing the first retaining ring from expanding, twisting and plastically deforming due to rotational centrifugal force, ensuring structural stability for long-term use; effectively preventing the phenomenon of material entering the gap between the roller and the inner wall of the machine;

[0027] 2. This utility model, through the setting of a second retaining ring and a second skeleton, uses the same principle as the first retaining ring and the same principle as the second skeleton. The main function of the second retaining ring and the second skeleton is to prevent material from entering the roller body after the exposed first retaining ring is damaged. The material is blocked by the support and the second retaining ring. Compared with cleaning the long inside of the roller body, cleaning the outer support and the second retaining ring is simpler and more convenient. Even if the first retaining ring is damaged and loses its seal, it is easy to clean.

[0028] 3. This utility model uses a bracket, ribs, and through holes. The bracket is assembled with the roller body through an interference fit, which ensures stable installation and prevents the structure from falling off. The ribs increase the structural strength of the bracket and prevent the bracket from deforming inward and affecting the limit of the interference fit. When disassembly is required, the worker only needs to pass the hook through the through hole and then apply force to the bracket through the hook to pull it out. This facilitates disassembly and assembly and avoids causing too much impact on the maintenance of the roller body. Attached Figure Description

[0036] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0037] The embodiments of this utility model will be described below based on its overall structure.

[0038] Example 1:

[0039] A type of grain crushing roller, such as Figures 1-6As shown, the system includes a roller body 1, with a support 2 connected inside the roller body 1. The support 2 is interference-fitted with the roller body 1. Multiple ribs 3 and through holes 4 are provided. Ribs 3 are connected to the outer surface of the support 2, and through holes 4 are provided on both sides of the ribs 3. A first retaining ring 5 and a second retaining ring 6 are connected inside the support 2. Both the first retaining ring 5 and the second retaining ring 6 are made of aramid short fiber reinforced fluororubber or polyester TPU. The first retaining ring 5 is trumpet-shaped, and one end of the second retaining ring 6 is bent outwards. A first skeleton 7 is provided inside the first retaining ring 5, and a second skeleton 8 is provided inside the second retaining ring 6. Both the first skeleton 7 and the second skeleton 8 are made of spring steel. The first retaining ring 5 is fixedly connected to the first skeleton 7, and the second retaining ring 6 is fixedly connected to the second skeleton 8. In use, the first retaining ring 5 can block the gap between the end face of the roller body 1 and the inner wall of the machine. To prevent material from entering, the first retaining ring 5 is trumpet-shaped and made of fluororubber, which has good elasticity, wear resistance and aging resistance. It can adapt to gaps of different widths and is suitable for high temperature and high speed environments, extending the service life of the structure. At the same time, the first retaining ring 5 is reinforced by the first skeleton 7 to prevent the first retaining ring 5 from expanding, twisting and plastically deforming due to rotational centrifugal force, ensuring structural stability for long-term use. The second retaining ring 6 works on the same principle as the first retaining ring 5, and the second skeleton 8 works on the same principle as the first skeleton 7. The main function of the second retaining ring 6 and the second skeleton 8 is to prevent material from entering the roller body 1 after the exposed first retaining ring 5 is damaged. The material is blocked by the support 2 and the second retaining ring 6. Compared with cleaning the inside of the longer roller body 1, cleaning the outer support 2 and the second retaining ring 6 is simpler and more convenient.

[0040] See Figure 1 and Figure 2 In the above embodiment, the roller body 1 is made of alloy tool steel. The surface of the roller body 1 is chrome-plated. Multiple serrations are evenly distributed on the outer ring of the roller body 1. When processing the roller body 1, alloy tool steel forging blanks are selected. Then, the inner and outer circles of the blank are rough machined by CNC machine tool, and the inner and outer circles and the spiral grooves of the outer ring are precision machined. After the inner and outer circles and the spiral grooves of the outer ring are processed, the blank is milled. Finally, the blank is quenched to obtain the roller body 1. After the roller body 1 is formed, the inner circle is precision machined again. The high-precision inner circle facilitates the subsequent installation of bearings and brackets 2. After the inner circle is precision machined for the second time, the roller body 1 can be electroplated to form a hard chrome electroplated layer on the surface of the roller body 1.

[0041] Example 2:

[0042] Based on the above embodiment one, in order to facilitate the replacement of the damaged first retaining ring 5, the following settings are now adopted.

[0043] See Figure 1 , Figure 2 and Figure 3In the above embodiment, the first bolt 9 passes through the inner ring of the bracket 2. The first retaining ring 5 is detachably connected to the bracket 2 through the first bolt 9. The worker puts the first retaining ring 5 into the bracket 2, and then limits the first retaining ring 5 by screwing in the first bolt 9. The installation operation is thus completed. If the first retaining ring 5 is damaged in the future, the first bolt 9 can be removed to stop limiting the first retaining ring 5, which makes it easy to replace the first retaining ring 5.

[0044] Example 3:

[0045] Based on the above embodiment one, in order to facilitate the replacement of the damaged second retaining ring 6, the following settings are now adopted.

[0046] See Figure 1 , Figure 2 and Figure 4 In the above embodiment, a second bolt 10 penetrates the outer surface of the bracket 2. The second retaining ring 6 is detachably connected to the bracket 2 through the second bolt 10. The worker puts the second retaining ring 6 into the bracket 2, and then limits the second retaining ring 6 by screwing in the second bolt 10. The installation operation is thus completed. If the second retaining ring 6 is damaged in the future, the second bolt 10 can be removed to stop limiting the second retaining ring 6, which makes it easy to replace the second retaining ring 6.

[0047] The implementation principle of this utility model is as follows: First, when processing the roller body 1, alloy tool steel forging blank is selected. Then, the inner and outer circles of the blank are rough machined by CNC machine tool, and the spiral grooves of the inner and outer rings and the outer ring are precision machined. After the inner and outer circles and the spiral grooves of the outer ring are processed, the blank is milled. Finally, the blank is quenched to obtain the roller body 1. After the roller body 1 is formed, the inner circle is precision machined again. The high-precision inner circle facilitates the subsequent installation of bearings and brackets 2. After the inner circle is precision machined for the second time, the roller body 1 can be electroplated to form a hard chrome electroplated layer on the surface of the roller body 1.

[0048] The bracket 2 is formed by sand casting using bearing steel or alloy tool steel. The inner and outer circles are precision machined to facilitate the insertion of the outer ring of the bracket 2 into the inner ring of the roller body 1 using an interference fit, while avoiding contact between the inner ring of the bracket 2 and the shaft. The first skeleton 7 and the second skeleton 8 are formed by bending spring steel and then heat-treated for shaping. After shaping, the surfaces of the first skeleton 7 and the second skeleton 8 are roughened by sandblasting to increase the bonding strength of the first retaining ring 5 and the second retaining ring 6. If the first retaining ring 5 and the second retaining ring 6 are made of fluororubber, the first skeleton 7 and the second skeleton 8 are placed in a mold, and the fluororubber raw material is placed on the surface of the first skeleton 7 and the second skeleton 8 through compression molding or injection molding. After the fluororubber raw material cools and solidifies, the first retaining ring 5 with the built-in first skeleton 7 and the second retaining ring 6 with the built-in second skeleton 8 are obtained. If the first retaining ring 5 and the second retaining ring 6 are made of TPU material, the first skeleton 7 and the second skeleton 8 are placed in a mold and processed by injection molding.

[0049] After all the structures are processed, the workers place the first retaining ring 5 and the second retaining ring 6 inside the bracket 2. Then, the first retaining ring 5 is limited by screwing in the first bolt 9, and the second retaining ring 6 is limited by screwing in the second bolt 10. This completes the installation. If the first retaining ring 5 and the second retaining ring 6 are damaged in the future, the first bolt 9 and the second bolt 10 can be removed to stop the limitation of the first retaining ring 5 and the second retaining ring 6, making it easy to replace them. Finally, the workers press the bracket 2 into the end face of the roller body 1 to complete the installation. The bracket 2 and the roller body 1 are assembled with an interference fit, which ensures stable installation and prevents the structure from falling off. The rib plate 3 increases the structural strength of the bracket 2 and prevents the bracket 2 from deforming inward and affecting the limitation of the interference fit. When disassembly is required, the workers only need to pass the hook through the through hole 4, and then apply force to the bracket 2 with the hook to pull it out.

[0050] In use, the first retaining ring 5 can block the gap between the end face of the roller body 1 and the inner wall of the machine, thereby preventing material from entering. The first retaining ring 5 is trumpet-shaped and made of fluororubber material, which has good elasticity, wear resistance and anti-aging properties. It can adapt to gaps of different widths and is suitable for high temperature and high speed environments, extending the service life of the structure. At the same time, the first retaining ring 5 is reinforced by the first skeleton 7 to prevent the first retaining ring 5 from expanding, twisting and plastically deforming due to rotational centrifugal force, ensuring structural stability for long-term use. The second retaining ring 6 works on the same principle as the first retaining ring 5, and the second skeleton 8 works on the same principle as the first skeleton 7. The main function of the second retaining ring 6 and the second skeleton 8 is to prevent material from entering the roller body 1 after the exposed first retaining ring 5 is damaged. The material is blocked by the support 2 and the second retaining ring 6. Compared with cleaning the inside of the longer roller body 1, cleaning the outer support 2 and the second retaining ring 6 is simpler and more convenient.
