Description

Technical Field

[0001] The utility model relates to a double-roll crusher, in particular to a double-roll crusher with good stability. Background Art

[0002] The double-roll crusher is a commonly used material crushing equipment, consisting of two rollers rotating relative to each other. It is mainly used for medium and fine crushing of medium or low hardness materials. The double-roll crusher has the advantages of simple structure, easy operation, low wear and high output.

[0003] Strong vibrations will be generated during the crushing process, which can easily cause loose components and increased wear, shortening the service life of the equipment. In addition, the lack of shock absorption will cause the crusher to become unstable at high speeds, affecting production efficiency and the consistency of the finished product particle size.

[0004] It should be noted that the above content falls within the technical cognition of the utility model applicant and does not necessarily constitute prior art. Utility Model Content

[0007] Shock-absorbing mechanisms are fixed on both sides of the top of the base:

[0008] The top end face of said sliding seat is fixedly provided with a toothed connecting strip which is cooperatively connected with said toothed connecting strip.

[0009] In one example, the top ends of the two stabilizing columns are fixedly connected to the two sides of the bottom end of the honeycomb shock-absorbing plate, a base is fixedly provided on the top end of the honeycomb shock-absorbing plate, connecting blocks are fixedly provided at both ends of the two sides of the base, each of the connecting blocks is slidably connected to the side wall of the corresponding fixed frame, and a double-roll crusher is fixedly provided on the top end of the base.

[0010] In one example, a limit plate is fixed to the other end of each of the through rods, and a second damping spring is sleeved on one side of the outer wall of each of the through rods, one end of each of the second damping springs contacts one side of the corresponding swivel seat, and the other end of each of the second damping springs contacts one side of the limit plate.

[0026] like Figures 1 to 3 As shown, the embodiment of the present invention provides a double-roll crusher with good stability, including a base 1:

[0027] The top two sides of the base 1 are fixed with a shock absorbing mechanism:

[0028] The shock absorbing mechanism includes a fixed frame 3 symmetrically arranged on one side of the top of the base 1, the bottom ends of the inner walls of the two fixed frames 3 are fixed with slide rods 8, the outer walls of the two slide rods 8 are slidably provided with slide seats 11, one side of the two slide seats 11 is rotatably provided with a rotating seat 10, and the interiors of the two rotating seats 10 are interspersed with a through rod 14, one end of the two through rods 14 is rotatably connected to the two sides of the inner wall of the corresponding clamping groove 13, and the two clamping grooves 13 are fixed on both sides of the outer wall of the fixed sleeve 15. A stabilizing column 12 is fixed to the top of the fixed sleeve 15, and an insert rod 22 is fixed to the bottom end of the fixed sleeve 15. The bottom end of the insert rod 22 is placed inside the sleeve 7, and a damping disk 20 is fixed to the bottom end of the insert rod 22. The edge of the damping disk 20 contacts the inner wall of the sleeve 7, and a first damping spring 21 is sleeved on the bottom of the outer wall of the insert rod 22. The bottom end of the first damping spring 21 contacts the top of the damping disk 20, and the top of the first damping spring 21 contacts the top of the inner wall of the sleeve 7.

[0029] Specifically, the top ends of the two stabilizing columns 12 are fixedly connected to the two sides of the bottom end of the honeycomb shock-absorbing plate 4, the top end of the honeycomb shock-absorbing plate 4 is fixedly provided with a base 5, and both ends of the two sides of the base 5 are fixedly provided with connecting blocks 9, each of the connecting blocks 9 is slidably connected to the side wall of the corresponding fixed frame 3, and the top end of the base 5 is fixedly provided with a double-roll crusher 6.

[0030] Specifically, a limit plate is fixedly provided at the other end of each of the through rods 14, and a second damping spring 16 is sleeved on one side of the outer wall of each of the through rods 14. One end of each of the second damping springs 16 contacts one side of the corresponding swivel seat 10, and the other end of each of the second damping springs 16 contacts one side of the limit plate.

[0031] Specifically, two support shaft seats are symmetrically fixed in the middle position of the bottom end of the base 1, and the inner sides of the two support shaft seats are rotatably connected to the two ends of the screw 17. The screw 17 is threadedly connected to the counterweight block 19. A drive motor 18 is fixed on one side of one of the support shaft seats, and the output end of the drive motor 18 is fixedly connected to one end of the screw 17.

[0032] Specifically, support frames 2 are fixedly provided on both sides of the bottom end of the base 1 .

[0033] Working Principle: The base 1 is placed on the ground, with the support frame 2 at the bottom providing stable support for the crusher. The roller crusher 6 is fixed to the base 5. The two ends of the base 5 are slidably connected to the side walls of the fixed frame 3 via connecting blocks 9, thereby maintaining stability during operation. The honeycomb damping plate 4 is located between the base 5 and the stabilizing column 12 to provide further shock absorption. The outer wall of the through rod 14 is equipped with a second damping spring 16, one end of which contacts one side of the swivel base 10 and the other end contacts the limit plate. When the double-roll crusher 6 vibrates during operation, the penetrating rod 14 can reduce some of the vibration under the buffering action of the second damping spring 16. At the same time, the first damping spring 21 in the sleeve 7 will also be compressed with the movement of the insertion rod 22 to further absorb the vibration. The bottom end of the first damping spring 21 contacts the top of the damping disk 20, and the top end contacts the top of the inner wall of the sleeve 7. The upper and lower buffering structures effectively reduce the impact and vibration generated by the operation of the double-roll crusher 6. The second damping spring 16 connected to the penetrating rod 14 and the swivel seat 10 will continue to absorb and buffer the vibration of the equipment, while the first damping spring 21 achieves a more effective shock absorption effect through the contact between the top of the inner wall of the sleeve 7 and the damping disk 20. The double-roll crusher 6 is fixed on the base 5, and the counterweight 19 is balanced and adjusted by the screw 17. The screw 17 is rotatably connected to the two support shaft seats at the bottom end of the base 1. One of the support shaft seats is connected to the drive motor 18. The drive motor 18 drives the screw 17 to rotate to realize the movement of the counterweight 19, ensuring the stability and load balance of the equipment during operation.
