Description

Technical Field

[0001] This application relates to the field of agricultural machinery and equipment, and in particular to an anti-wear device for a press machine. Background Technology

[0002] As an important type of agricultural machinery, soil compactors are widely used in soil treatment. Their main functions are to compact the soil, level the surface, and promote close contact between seeds and soil, thereby improving crop germination rate and growth quality. With the continuous improvement of agricultural mechanization, the application scope of soil compactors in agricultural production has gradually expanded, playing an important role in improving agricultural production efficiency, reducing labor intensity, and improving the farmland environment.

[0003] In traditional compactor designs, guide wheel frames are typically used to support and move the compactor wheel, and these frames are coordinated with support beams on the compactor body. When encountering uneven ground, the compactor wheel may be higher on one side than the other. Simultaneously, the compactor wheel will cause the guide wheel frame supporting it to also be higher on one side. The higher side of the guide wheel frame will directly collide and rub against the support beams on the compactor body. Repeated collisions and friction will inevitably cause severe wear to the guide wheel frame and support beams, thereby reducing the equipment's lifespan and performance, and increasing maintenance costs and downtime. Utility Model Content

[0004] In order to reduce the collision and friction between the guide wheel frame and the support beam when the compactor is dealing with uneven land, and to improve the service life and performance of the equipment, this application provides an anti-wear device for the compactor.

[0005] This application provides an anti-wear device for a press, which adopts the following technical solution:

[0006] A wear-resistant device for a press machine includes a press machine body, a support beam disposed on the press machine body, a guide wheel frame for supporting the press wheel, a mounting frame fixed above the guide wheel frame, a wear-resistant seat slidably connected vertically within the mounting frame, a universal ball disposed on the top of the wear-resistant seat, and a universal seat rotatably sleeved on the outside of the universal ball.

[0007] The support beam and the guide wheel frame are spaced apart; multiple damping rods are fixed between the bottom of the anti-wear seat and the mounting frame, and buffer springs are sleeved on the outside of the damping rods.

[0008] By adopting the above technical solution, when the press machine encounters uneven ground during operation, the press wheel drives the guide wheel frame to be higher on one side and lower on the other. A vertically sliding anti-wear seat is located within the mounting frame above the guide wheel frame. The top of the anti-wear seat has a universal ball joint and a universal seat rotatably fitted on its outer side. The raised guide wheel frame will not directly collide with the support beam; instead, the universal ball joint will contact the support beam first. Simultaneously, the universal ball joint drives the universal seat and the anti-wear seat to move downwards, compressing the buffer spring. Multiple damping rods between the bottom of the anti-wear seat and the mounting frame, along with the buffer spring fitted on its outer side, provide cushioning, reducing the impact force. This anti-wear device, on the one hand, allows the universal ball joint to rotate flexibly, avoiding direct collision and friction between the guide wheel frame and the support beam, reducing wear on both. On the other hand, the damping rods and buffer springs further buffer the impact force, reducing equipment vibration and noise. Therefore, the overall effect is to extend the equipment's service life, reduce maintenance costs, and improve the performance and production efficiency of the press machine.

[0009] Optionally, the top of the anti-wear seat has an installation groove from top to bottom, the universal seat is inserted into the installation groove, a locking block is slidably connected in the horizontal direction inside the anti-wear seat, and the universal seat has a locking groove around its circumference that matches the locking block, the locking block can be inserted into the locking groove.

[0010] By adopting the above technical solution, the universal joint is inserted into the mounting groove opened on the top of the wear-resistant seat. Then, the locking block that slides horizontally inside the wear-resistant seat will match and be inserted into the locking groove around the universal joint, thereby stably fixing the universal joint in the mounting groove of the wear-resistant seat. This prevents the universal joint from coming out of the mounting groove when the pressure wheel causes the guide wheel frame to tilt or shake violently due to uneven ground, thus ensuring the stability and reliability of the connection between the universal joint and the wear-resistant seat.

[0011] Optionally, a locking spring is fixed to the side of the locking block away from the locking groove, and the other end of the locking spring is fixed to the inner wall of the anti-wear seat. The locking spring always drives the locking block to move toward the locking groove.

[0012] By adopting the above technical solution, when it is necessary to fix the universal joint in the mounting groove of the anti-wear seat, the universal joint is inserted into the mounting groove, and the locking spring drives the locking block to move toward the locking groove under the elastic force until the locking block is inserted into the locking groove, thereby locking the universal joint and preventing the universal joint from loosening or falling out.

[0013] Optionally, the locking block has an unlocking groove, the end face of the unlocking groove near the locking spring is inclined, and an unlocking rod is slidably connected to the outside of the anti-wear seat, one end of the unlocking rod extending into the anti-wear seat and abutting against the inclined surface of the unlocking groove.

[0014] By adopting the above technical solution, when it is necessary to unlock and replace the universal joint, press the unlocking lever so that one end of the unlocking lever extends into the anti-wear seat and abuts against the inclined surface of the unlocking groove near the locking spring. As the unlocking lever moves, the inclined surface pushes the locking block to overcome the elastic force of the locking spring and slide away from the locking groove until the locking block is disengaged from the locking groove, thereby releasing the lock on the universal joint. When it is necessary to disassemble or replace the universal joint, simply push the unlocking lever to easily complete the unlocking process. The operation is simple and convenient.

[0015] Optionally, a release spring is fixed at the bottom of the mounting groove, the top of the release spring contacts the bottom of the universal joint, and the release spring is used to drive the universal joint to move upward to disengage from the mounting groove.

[0016] By adopting the above technical solution, when the universal joint needs to be replaced or repaired, since the top of the release spring contacts the bottom of the universal joint and is fixed to the bottom of the mounting slot, the release spring will release elastic potential energy to drive the universal joint to move upward, so that the universal joint is removed from the mounting slot. This allows the staff to easily and quickly remove the universal joint from the mounting slot, which facilitates the replacement or repair of the universal joint, avoids a complicated disassembly process, and improves maintenance efficiency.

[0017] Optionally, a limiting seat is fixed inside the mounting bracket, and the maximum distance between the bottom of the anti-wear seat and the top of the limiting seat is less than the maximum height at which the anti-wear seat can extend beyond the outside of the mounting bracket.

[0018] By adopting the above technical solution, when the anti-wear seat slides vertically in the mounting bracket, the limiting seat can limit the sliding range of the anti-wear seat. When the anti-wear seat slides downward in the mounting bracket to a certain position, the bottom of the anti-wear seat will contact the top of the limiting seat, preventing the anti-wear seat from extending excessively into the mounting bracket, thereby giving full play to the wear reduction effect of the universal ball.

[0019] Optionally, the inner wall of the universal seat is provided with a universal groove that is adapted to the universal ball, and the bottom wall of the universal groove is provided with a plurality of pressure-bearing balls.

[0020] By adopting the above technical solution, when the support beam contacts the universal ball, the universal ball rotates in the universal seat. At this time, multiple pressure-bearing balls on the bottom wall of the universal groove will roll along with the rotation of the universal ball. The arrangement of multiple pressure-bearing balls can reduce the frictional resistance between the universal ball and the universal seat, making the rotation of the universal ball in the universal seat smoother.

[0021] Optionally, the pressure-bearing balls are evenly distributed along the circumference of the bottom wall of the universal groove, and the centers of the pressure-bearing balls are located within the same spherical surface.

[0022] By adopting the above technical solution, when the universal ball rotates in the universal seat, the pressure-bearing balls, which are evenly distributed around the circumference and whose centers are located in the same spherical surface, will roll and contact with the universal ball. Because they are evenly distributed around the circumference, the rotation of the universal ball in all directions is more stable and smooth, reducing the jamming phenomenon caused by uneven local force. Furthermore, when the universal ball rotates, the pressure can be evenly distributed to the bottom wall of the universal groove through the pressure-bearing balls, thus extending the service life of the universal ball and the universal seat.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. The anti-wear device has the following advantages: First, the universal ball can rotate flexibly, which can avoid direct collision and friction between the guide wheel frame and the support beam, reducing wear on both. Second, the damping rod and buffer spring can further buffer the impact force, reduce equipment vibration and noise, thereby achieving the overall effect of extending the service life of the equipment, reducing maintenance costs, and improving the performance and production efficiency of the press.

[0025] 2. The locking block, locking groove, and locking spring securely fix the universal joint in the mounting groove of the anti-wear seat, preventing the universal joint from coming out of the mounting groove when the pressure wheel causes the guide wheel frame to tilt or shake violently due to uneven ground, thus ensuring the stability and reliability of the connection between the universal joint and the anti-wear seat.

[0026] 3. When the universal joint needs to be replaced or repaired, since the top of the release spring contacts the bottom of the universal joint and is fixed to the bottom of the mounting slot, the release spring will release elastic potential energy to move the universal joint upward, causing the universal joint to detach from the mounting slot. This allows the staff to easily and quickly remove the universal joint from the mounting slot, facilitating the replacement or repair of the universal joint, avoiding a complicated disassembly process, and improving maintenance efficiency.

[0032] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0033] This application discloses an anti-wear device for a press. (Refer to...) Figure 1 and Figure 2 The anti-wear device of the press includes a press body 1, a support beam 2, a guide wheel frame 3, a mounting frame 4, an anti-wear seat 5, a ball joint 6, and a universal joint 61. The support beam 2 is mounted on the press body 1, and the guide wheel frame 3 supports the press wheel 31. The support beam 2 and the guide wheel frame 3 are spaced apart. The mounting frame 4 is fixed above the guide wheel frame 3, and the anti-wear seat 5 is vertically slidably connected within the mounting frame 4. The ball joint 6 is located on top of the anti-wear seat 5, and the universal joint 61 is rotatably sleeved on the outside of the ball joint 6.

[0034] Reference Figure 2 and Figure 3 Multiple damping rods 7 are fixed between the bottom of the anti-wear seat 5 and the mounting bracket 4. A buffer spring 71 is sleeved on the outside of each damping rod 7. The damping rods 7 and the buffer spring 71 work together to buffer and reduce shock, effectively mitigating the impact force generated by the collision between the guide wheel frame 3 and the support beam 2. A limiting seat 72 is fixed inside the mounting bracket 4. The maximum distance between the bottom of the anti-wear seat 5 and the top of the limiting seat 72 is less than the maximum height the anti-wear seat 5 can extend beyond the mounting bracket 4. The limiting seat 72 restricts the sliding range of the anti-wear seat 5. When the anti-wear seat 5 slides downwards to a certain position within the mounting bracket 4, the bottom of the anti-wear seat 5 contacts the top of the limiting seat 72, preventing the anti-wear seat 5 from excessively extending into the mounting bracket 4, thus fully utilizing the wear-reducing effect of the universal ball 6.

[0035] When the press is working, if the ground is uneven, the press wheel 31 drives the guide wheel frame 3 to be higher on one side and lower on the other. There is a vertically sliding anti-wear seat 5 in the mounting frame 4 above the guide wheel frame 3. The top of the anti-wear seat 5 has a universal ball 6 and a universal seat 61 rotatably sleeved on its outside. The raised guide wheel frame 3 will not directly collide with the support beam 2. Instead, the universal ball 6 will contact the support beam 2 first. At the same time, the universal ball 6 drives the universal seat 61 and the anti-wear seat 5 to move downward to compress the buffer spring 71. The multiple damping rods 7 between the bottom of the anti-wear seat 5 and the mounting frame 4 and the buffer spring 71 sleeved on the outside can play a buffering role and reduce the impact force of the collision.

[0036] Specifically, refer to Figure 2 and Figure 3 The anti-wear seat 5 has a mounting groove 51 on its top from top to bottom, into which the universal joint 61 is inserted. A locking block 52 is slidably connected horizontally inside the anti-wear seat 5. The universal joint 61 has a locking groove 53 around its circumference that matches the locking block 52, allowing the locking block 52 to be inserted into the locking groove 53. The end of the locking block 52 near the universal joint 61 is wedge-shaped, facilitating insertion into the locking groove 53. A locking spring 54 is fixed to the side of the locking block 52 away from the locking groove 53, and the other end of the locking spring 54 is fixed to the inner wall of the anti-wear seat 5. When the locking spring 54 is compressed, it can drive the locking block 52 to move towards the locking groove 53, ensuring a secure lock on the universal joint 61. An unlocking groove 521 is provided on the locking block 52, with the end face of the unlocking groove 521 near the locking spring 54 being beveled. The anti-wear seat 5 is vertically slidably connected to an unlocking rod 55. The bottom end of the unlocking rod 55 extends into the anti-wear seat 5 and abuts against the inclined surface of the unlocking groove 521. A release spring 56 is fixed at the bottom of the mounting groove 51. The top end of the release spring 56 contacts the bottom of the universal seat 61. When the universal seat 61 is unlocked, the release spring 56 is used to drive the universal seat 61 to move upward to disengage from the mounting groove 51, making it convenient to disassemble and maintain the universal seat 61.

[0037] After the universal joint 61 is inserted into the mounting slot 51 on the top of the anti-wear seat 5, the locking spring 54, driven by elastic force, moves the locking block 52 toward the locking slot 53 until the locking block 52 is inserted into the locking slot 53, thereby stably fixing the universal joint 61 in the mounting slot 51 of the anti-wear seat 5. This prevents the universal joint 61 from coming out of the mounting slot 51 when the pressure wheel 31 tilts or shakes violently due to uneven ground. When it is necessary to unlock and replace the universal joint 61, press the unlocking lever 55 so that one end of the unlocking lever 55 extends into the anti-wear seat 5 and abuts against the inclined surface of the unlocking slot 521 near the locking spring 54. As the unlocking lever 55 moves, the inclined surface pushes the locking block 52 to overcome the elastic force of the locking spring 54 and slide away from the locking slot 53 until the locking block 52 comes out of the locking slot 53, thereby releasing the lock on the universal joint 61.

[0038] Specifically, refer to Figure 3 and Figure 4 The inner wall of the universal joint 61 is provided with a universal groove 611 that is adapted to the universal ball 6; the bottom wall of the universal groove 611 is provided with multiple pressure-bearing balls 62, which are evenly distributed along the circumference of the bottom wall of the universal groove 611, and the centers of the multiple pressure-bearing balls 62 are located in the same spherical surface. The function of the pressure-bearing balls 62 is to reduce the friction between the universal ball 6 and the universal groove 611, and improve the flexibility and smoothness of rotation. The pressure-bearing balls 62 are made of hard alloy material to ensure their wear resistance and load-bearing capacity.

[0039] The implementation principle of an anti-wear device for a roller press according to an embodiment of this application is as follows: When the roller press operates on uneven ground, the roller press 31 will cause the guide wheel frame 3 to tilt due to the undulation of the ground. At this time, the anti-wear seat 5 can flexibly adjust its angle through the cooperation of the universal ball 6 and the universal seat 61 to adapt to the tilting state of the guide wheel frame 3. At the same time, the damping rod 7 and the buffer spring 71 absorb and disperse the impact force between the guide wheel frame 3 and the support beam 2, avoiding direct collision and friction between the two. The locking block 52 and the locking spring 54 on the anti-wear seat 5 can ensure the stable installation of the universal seat 61. When maintenance is required, the universal seat 61 can be easily disassembled by pushing the unlocking rod 55. In summary, this anti-wear device reduces the wear of the guide wheel frame 3 and the support beam 2, reduces maintenance costs and downtime compared to traditional roller presses, and improves agricultural production efficiency.

[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
