Description

Technical Field

[0001] This utility model relates to the field of agricultural and livestock machinery and devices, specifically a corn silage kernel crushing and shredding roller. Background Technology

[0002] With the continuous development of my country's animal husbandry and the improvement of the scale and standardization of dairy farms, corn silage has become one of the important feed ingredients for dairy cows. The demand and quality of corn silage are also increasing year by year. If the corn in the silage is not sufficiently crushed, it will not be conducive to the digestion and absorption of dairy cows. Although the existing corn silage kernel crushing rollers have kernel crushing functions, the particle size of the crushed kernels is too small and the silage fiber is too short. The physical properties of silage fiber are related to its length. The longer the fiber, the more it can stimulate rumination in dairy cows. During rumination, dairy cows produce saliva, which can buffer the pH value of the rumen and keep the rumen healthy. The higher the content of physically effective fiber in silage, the better it is for stabilizing and improving the milk fat percentage.

[0003] Currently, in order to increase the physical effective fiber content of corn silage, reduce the rumen passage rate of dairy cow digesta, and thoroughly crush the corn kernels to facilitate digestion and absorption by dairy cows and increase milk production, corn silage kernel crushing and shredding rollers are used. These rollers can more thoroughly "shred" the stems and leaves of the plant and the corn kernels, while also increasing the fiber length of the silage. Because the fibers are longer, they take longer to digest in the rumen. Therefore, corn silage processed using kernel crushing and shredding rollers has a higher digestibility, resulting in higher milk production for dairy cows.

[0004] Existing corn silage kernel crushing and shredding rollers are installed inside the frame of the corn silage machine. However, there is a gap between the corn silage machine and the shredding roller, allowing some material to fall into the shredding roller through this gap. Because the shredding roller has an elastic bushing consisting of an outer ring, a rubber ring, and an inner ring, the material falling into the shredding roller may come into contact with the rubber ring. Since the rubber ring is made of rubber, when the material rubs against the rubber ring for a long time, it will accelerate the wear rate of the rubber ring, reduce the service life of the rubber ring, reduce the protective effect of the rubber ring, and also reduce the service life of the elastic bushing. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a corn silage kernel crushing and shredding roller to solve the technical problem of poor protection effect on the rubber ring.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a corn silage kernel crushing and shredding roller, comprising a roller, with outer rings on both sides of the inner side of the roller, an inner ring inside the outer ring, and a middle ring installed between the inner and outer rings, and a roller shaft inside the roller, with threaded grooves on one side of both outer rings, and threaded heads threadedly connected inside the threaded grooves, with a protective cover installed at one end of the threaded heads, and toothed blades provided on the outer wall of the roller.

[0007] By adopting the above technical solution, the toothed blade can crush corn kernels and flatten stalks, while the V-shaped blade can tear and shred the corn cobs and straw in corn silage.

[0008] Furthermore, a tensioning bushing is installed between the roller shaft and the inner ring, and the roller shaft passes through the inner ring.

[0009] By adopting the above technical solution, the roller shaft and the inner ring can be locked together by the expansion sleeve.

[0010] Furthermore, one end of the protective cover is equipped with multiple anti-slip protrusions.

[0011] By adopting the above technical solution, it is convenient for staff to rotate the protective cover using the anti-slip protrusions.

[0018] Furthermore, stepped shafts are provided at both ends of the roller shaft, and the stepped shaft diameter is matched with the bearing seat of the corn silage machine frame. The inner ring, middle ring and outer ring form an elastic bushing.

[0019] By adopting the above technical solution, the elastic bushing composed of an inner ring, a middle ring, and an outer ring can support the roller shaft.

[0020] Furthermore, the protective cover is located on one side of the middle ring, and the diameter of the protective cover is larger than the diameter of the middle ring.

[0021] By adopting the above technical solution, the protective cover can shield and protect the middle ring, preventing materials from directly contacting the middle ring.

[0022] Furthermore, the protective cover is made of ultra-high molecular weight polyethylene material.

[0023] By adopting the above technical solutions, the wear resistance of the protective cover can be improved.

[0024] Furthermore, the protective cover is detachably connected to the outer ring via a threaded head and a threaded groove.

[0025] By adopting the above technical solution, when installing the protective cover, the staff can rotate the protective cover to screw the threaded head into the thread groove, thereby completing the installation of the protective cover.

[0026] In summary, the present invention has the following main advantages:

[0027] 1. This utility model is equipped with a protective cover, which can protect the middle ring made of rubber material, preventing material from falling from the edge of the roller and equipment into the space between the roller and the outer ring, thereby preventing the material from contacting the middle ring and preventing the middle ring from contacting the material and rubbing against it, thus improving the protection effect of the middle ring and extending the service life of the middle ring.

[0028] 2. This utility model, by providing a threaded head and a threaded groove, allows workers to place the protective cover on the roller shaft and then rotate it to screw the threaded head into the threaded groove, thereby completing the installation of the protective cover, preventing it from moving and improving its stability.

[0029] 3. This utility model is equipped with anti-slip protrusions, which make it easy for workers to rotate the protective cover by rotating the anti-slip protrusions so that the protective cover can be unscrewed from the outer ring. Attached Figure Description

An inner ring 3 is located inside the outer ring 2, and a middle ring 4 is installed between the inner ring 3 and the outer ring 2. A roller shaft 6 is also installed inside the roller 1. Threaded grooves 9 are opened on one side of each of the two outer rings 2, and threaded heads 10 are threaded into the inner threads of the grooves 9. A protective cover 11 is installed at one end of the threaded head 10. Toothed blades 8 are provided on the outer wall of the roller 1. The front angle of the toothed blades 8 is 10°, and the back angle is 45°. The tips of the toothed blades 8 on the outer ring of the roller 1 are spirally opened with a 50° V-shaped cutting edge along the axial direction. The spiral V-shaped cutting edge pitch is 8.5 mm, and the V-shaped cutting edge depth is 3 mm. The toothed blades 8 can crush corn kernels and flatten stalks. A tensioning bushing 5 is installed between the roller shaft 6 and the inner ring 3. The roller shaft 6 passes through the inner ring 3, allowing the roller shaft 6 and the inner ring 3 to be locked together by the tensioning bushing 5. The middle ring 4 is made of high-strength rubber.

[0042] See Figures 1-6The roller 6 has stepped shafts at both ends, and the stepped shaft diameter matches the bearing seat of the corn silage machine frame. The inner ring 3, middle ring 4 and outer ring 2 form an elastic bushing, which supports the roller 6. The protective cover 11 is located on one side of the middle ring 4. The diameter of the protective cover 11 is larger than that of the middle ring 4. The protective cover 11 can shield and protect the middle ring 4 to prevent the material from directly contacting the middle ring 4. The protective cover 11 is made of ultra-high molecular weight polyethylene material to improve the wear resistance of the protective cover 11. The protective cover 11 is detachably connected to the outer ring 2 through the threaded head 10 and the threaded groove 9. When installing the protective cover 11, the operator can rotate the protective cover 11 so that the threaded head 10 can be screwed into the threaded groove 9, thereby completing the installation of the protective cover 11.

[0043] Example 2:

[0044] Based on the above embodiment 1, the following structure will be set to facilitate the rotation of the protective cover 11 by the staff.

[0045] Specifically, one end of the protective cover 11 is equipped with multiple anti-slip protrusions 7, which make it convenient for workers to rotate the protective cover 11 through the anti-slip protrusions 7, thereby facilitating the installation of the protective cover 11.

[0046] Example 3:

[0047] Based on the above embodiment 1, in order to improve the hardness of roller 1, inner ring 3 and outer ring 2, the following materials will be used to make roller 1, inner ring 3 and outer ring 2.

[0048] See Figures 1-5 Roller 1 is made of alloy tool steel forging to improve its hardness and wear resistance. Inner ring 3 and outer ring 2 are made of alloy tool steel to improve their hardness and wear resistance.

[0049] The working principle of this utility model is as follows: First, when installing the protective cover 11, the operator can put the protective cover 11 on the roller 6, and then rotate the protective cover 11 through the anti-slip protrusion 7 so that the threaded head 10 is screwed into the threaded groove 9, thereby completing the installation of the protective cover 11 and preventing the protective cover 11 from moving. Next, the roller body is installed in the frame of the corn silage machine, and the outer wall of the roller 1 is provided with toothed blades 8. When the roller 1 rotates, it can drive the toothed blades 8 to rotate, and the toothed blades 8 can crush the corn kernels. The protective cover 11 can protect the middle ring 4 made of rubber material, preventing the material from falling from the roller 1 and the edge of the equipment into the space between the roller 1 and the outer ring 2, thereby preventing the material from contacting the middle ring 4 and preventing the middle ring 4 from contacting the material and rubbing against it, which would cause damage to the middle ring 4.
