Description

Technical Field

[0001] This invention relates to the field of hay bale machine technology, specifically to a roller with a buffer function. Background Technology

[0002] A hay baler mainly includes a frame, drive shaft, drive wheel, feeding mechanism, driven shaft, driven sprocket, clutch, clutch pawl, drive rope pulley, worktable, rope pulley, rope, lever, return torsion spring, etc.; it also includes a clamping mechanism drive sprocket, a clamping mechanism driven shaft (which also has a clutch, clutch pawl), a limit ratchet, a clamping mechanism driven sprocket, a clamping mechanism drive rope pulley, a return torsion spring, a sector wheel, a sector wheel shaft, clamping device, and a hay rope bracket, hay rope, etc. Its advantages are fast hay baling and labor-saving operation. The feeding mechanism uses equidistantly arranged rollers to drive their rotation for feeding.

[0003] Existing rollers all use a plate welding method to fix the roller shafts on both sides to the feeding table. During use, the transmission stop block connecting the roller shaft and the roller is welded to the roller and is prone to wear, and the wear is very serious. This makes the roller shaft prone to breakage on the roller, thus affecting the normal working performance of the roller.

[0004] Therefore, those skilled in the art have provided a roller with a buffer function to solve the problems mentioned in the background art. Summary of the Invention

[0031] As shown in the attached diagram of the instruction manual. Figures 1-8 As shown, a roller with a buffer function includes a roller body 1 and a transmission stop 2 disposed inside one side of the roller body 1. A first fixing groove 3 is formed on one side surface of the transmission stop 2. A second fixing groove 4 is formed on the inner wall of the first fixing groove 3. A spring 5 is disposed on the inner wall of the second fixing groove 4. The spring 5 is elastically connected to a first fixing block 6. A first positioning post 7 is disposed on the inner bottom wall of the first fixing groove 3. An installation block 8 is inserted into the first fixing groove 3. Both sides of the installation block 8 are in contact with the first fixing block 6. A first positioning hole 9, adapted to the first positioning post 7, is formed at the bottom of the installation block 8. A buffer pad 10 is fixedly connected to the outside of the installation block 8 extending out of the first fixing groove 3. The buffer pad 10 is in contact with the inner wall of the roller body 1. Figures 2-4As shown, in specific implementation, the mounting block 8 is inserted into the first fixing groove 3. When the first positioning hole 9 on the mounting block 8 is inserted into the first positioning post 7, the mounting block 8 is installed in the groove. The spring 5 in the second fixing groove 4 pushes the first fixing block 6 to squeeze and lock the mounting block 8, thereby realizing the installation of the buffer pad 10 on the transmission stop 2. By setting the buffer pad 10 between the transmission stop 2 and the inner wall of the roller body 1, the transmission stop 2 used to connect the roller shaft and the roller body 1 is provided with a buffer pad 10 structure, which can alleviate the wear between the roller body 1 and the roller shaft, reduce the impact of wear, enhance the connection stability between the roller body 1 and the roller shaft, and make the roller shaft less likely to break, ensuring the normal working performance of the roller body 1.

[0032] Specifically, such as Figure 2 , Figure 5 As shown, a third fixing groove 11 is provided on the other side surface of the transmission block 2. A second fixing block 12 that contacts the inner wall of the roller body 1 is provided inside the third fixing groove 11. A first fixing disk 13 is movably provided at one end of the transmission block 2. The other end of the transmission block 2 extends out of the roller body 1 and a first roller shaft 14 is fixedly provided at its end. The setting of the second fixing block 12 can increase the frictional resistance between the transmission block 2 and the inner wall of the roller. With the first fixing disk 13, the roller body 1 can be better and more securely connected. The first roller body 1 is connected to an external drive motor to drive the roller body 1 to rotate for material conveying.

[0033] As a preferred embodiment of the present invention, in order to facilitate quick assembly and disassembly of the transmission stop 2 and the second fixing block 12, it is preferable that, for example... Figure 5 As shown, the surface of the first fixed plate 13 is provided with a slot 15 that is adapted to the transmission stop 2, the inner bottom wall of the third fixed groove 11 is provided with a fixed post 16, and the bottom surface of the second fixed block 12 is provided with a fixing hole 17 that is adapted to the fixed post 16.

[0034] like Figure 2 As shown, in this embodiment, the surface of the transmission stop 2 is provided with an anti-slip strip 18 in an annular shape, and a first anti-misoperation buckle 19 is provided on one side of the surface of the first roller shaft 14. The first anti-misoperation buckle 19 is mainly used to prevent misoperation and prevent the first roller shaft 14 from docking with the wrong external equipment, thereby improving the use effect of the device. The anti-slip strip 18, together with the second fixing block 12, further improves the connection sealing between the inner wall of the roller body 1 and the transmission stop 2.

[0035] As a preferred embodiment of the present invention, in order to avoid severe wear of the roller body 1 during operation, it is preferable that, for example... Figure 8As shown, a first wear-resistant layer 20 is provided on the outer wall of the roller body 1, and a second wear-resistant layer 21 is provided on the inner wall of the roller body 1. The central axes of the first wear-resistant layer 20 and the second wear-resistant layer 21 coincide. The first wear-resistant layer 20 is made of alumina ceramic material, and the second wear-resistant layer 21 is made by chrome plating. The selected materials have extremely high wear resistance, which makes the device less prone to wear and extends its service life.

[0036] Specifically, such as Figure 7 , Figure 8 As shown, the roller body 1 has mating holes 22 on both sides of its surface that are compatible with the buffer pad 10. The roller body 1 has a vent hole 23 on one side of the mating hole 22. The vent hole 23 ensures air circulation when the roller body 1 is working, and ensures that its interior is dry while dehumidifying.

[0037] Specifically, such as Figure 6 As shown, two sets of second fixed disks 24 are equidistantly arranged inside the other side of the roller body 1. A second roller shaft 25 is fixedly arranged between the two sets of second fixed disks 24. A second anti-misalignment buckle 26 is provided on one side of the surface of the second roller shaft 25. A rubber pad 27 is provided on the outer wall of each set of second fixed disks 24. The rubber pad 27 is used to improve the connection sealing between the second fixed disk 24 and the inner wall of the roller body 1. The second anti-misalignment buckle 26 is mainly used to prevent misalignment and prevent the second roller shaft 25 from being connected to the wrong external equipment, thereby improving the use effect of the device.

[0038] As a preferred embodiment of the present invention, in order to enhance the connection stability between each roller shaft and the external docking equipment, it is preferable that, for example... Figure 2 , Figure 6 As shown, both the ends of the first roller shaft 14 and the second roller shaft 25 are provided with end caps 28. The end caps 28 can cover the ends of each roller shaft, thereby indirectly waterproofing the operation.

[0039] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
