Description

Technical Field

[0001] This application relates to the field of crusher technology, and in particular to a device for preventing material accumulation in the feed roller hopper of a hammer crusher. Background Technology

[0002] A hammer crusher is a device that crushes materials through impact. It comes in single-rotor and double-rotor configurations. It's a primary crusher that directly crushes materials with a maximum particle size of 600-1800 mm to 25 mm or less. Hammer crushers are suitable for crushing medium-hardness materials such as limestone, slag, coke, and coal in industries such as cement, chemical, power, and metallurgy. To ensure a stable feed to the hammer crusher, a feed roller hopper is usually installed at the inlet.

[0003] Feed roller hoppers typically use two opposing feed rollers to feed materials into the hopper. However, during the feeding process, if the material blocks are large, they may pile up on the two feed rollers, causing material to accumulate in the hopper. The current method to prevent material accumulation in the hopper is to use a vibrator. The vibrator vibrates the hopper to move the large material blocks, thus solving the problem of material pushing in the hopper. However, the vibrator will impact the hopper's own structure, reducing the hopper's service life. Summary of the Invention

[0004] To address the issue of vibrators impacting the silo's structure and reducing its lifespan, this application provides a device to prevent material accumulation in the feed roller silo of a hammer crusher.

[0005] The technical solution provided in this application for a hammer crusher feed roller hopper anti-stacking device is as follows:

[0006] A hammer crusher feed roller hopper anti-stacking device includes a hopper and two feed rollers rotatably disposed within the hopper. The hopper is equipped with a drive unit that drives the two feed rollers to rotate relative to each other. Each feed roller is equipped with a crushing claw. The feed rollers drive the crushing claws to rotate via a transmission unit. The crushing claws are arranged radially along the feed rollers and are used to crush large pieces of material. The feed rollers are connected to the crushing claws via a connecting unit, and the connecting unit can drive the crushing claws to reciprocate along the axial direction of the feed rollers. The hopper is equipped with a control unit for controlling the connection and disconnection between the feed rollers and the connecting unit.

[0007] By adopting the above technical solution, when the silo is working, the drive unit drives two feeding rollers to rotate, sending the material in the silo to the discharge port. When large pieces of material overlap the two feeding rollers, causing material accumulation, the control unit controls the connecting unit to connect with the feeding rollers. The feeding rollers drive the crushing claws to slide along the axial direction of the feeding rollers through the connecting unit. At the same time, the feeding rollers drive the crushing claws to rotate through the transmission unit, crushing the large pieces of material overlapping the feeding rollers. This effectively avoids the accumulation of material in the silo. Compared with the anti-accumulation method of vibrators, the solution of this application is less likely to cause impact on the silo structure, thereby improving the service life of the silo.

[0008] In one specific implementation, the transmission unit includes a transmission ring, the feed roller has a polygonal cross-section, the transmission ring is slidably sleeved on the feed roller and engages with the feed roller in a concave-convex fit, and the crushing claw is fixedly mounted on the transmission ring.

[0009] By adopting the above technical solution, the crushing claw can slide along the feeding roller while the transmission ring cooperates with the feeding roller, thereby improving the convenience of the crushing claw's movement and rotation.

[0010] In one specific implementation, the connecting unit includes a connecting rod, a rotating disk, and a reciprocating screw. The connecting rod is arranged along the axial direction of the feeding roller. The feeding roller is connected to the hopper via a rotating support. One end of the connecting rod is fixedly connected to the transmission ring, and the other end passes through the rotating support and is fixedly connected to the rotating disk. The axis of the rotating disk is collinear with the axis of the feeding roller. The reciprocating screw is coaxial with the rotating disk and fixedly mounted on the outer wall of the hopper. The drive disk is threaded onto the reciprocating screw. The control unit can control the rotating disk to drive the drive disk to move and rotate.

[0011] By adopting the above technical solution, when material accumulates in the hopper, the control unit controls the rotating disk to drive the drive disk to rotate. While the drive disk is rotating, it slides under the guidance of the reciprocating screw. The drive disk drives the rotating disk to move, and the rotating disk drives the transmission ring to slide on the feeding roller through the connecting rod, which makes the crushing claw more reliable in crushing large pieces of material.

[0012] In one specific implementation, the rotating support includes a support disk embedded in the hopper wall and rotatably connected, the feeding roller is coaxially fixed to the support disk, and the connecting rod passes through the support disk and is slidably connected to the support disk.

[0013] By adopting the above technical solution and setting up a support plate, the ease of rotation of the connecting rod can be improved.

[0014] In one specific implementation, the control unit includes a linear drive mechanism and a linkage block. The linkage block is slidably inserted into the rotating disk and can slide along the axial direction of the rotating disk. The drive disk has a linkage slot for the linkage block to be inserted. The rotating disk has a telescopic spring for pushing the linkage block into the linkage slot. The linear drive mechanism is used to drive the rotating disk closer to the drive disk, so that the linkage block can be inserted into the linkage slot. The drive disk drives the rotating disk to rotate through the cooperation of the linkage block and the linkage slot.

[0015] By adopting the above technical solution, when the rotating disk drives the driving disk to rotate, the linear drive mechanism drives the rotating disk to slide towards the driving disk, and then the connecting block is inserted into the connecting groove, so that the rotating disk can drive the driving disk to rotate; the telescopic spring first pushes the connecting block to abut against the driving disk, and when the connecting block rotates to the position of the connecting groove, the telescopic spring pushes the connecting block to insert into the connecting groove, thereby improving the reliability of the connecting block inserting into the connecting groove.

[0016] In one specific implementation scheme, the linkage groove is an arc-shaped groove, and the center of the trajectory of the linkage groove is collinear with the axis of the drive disk.

[0017] By adopting the above technical solution and setting the linkage groove as an arc-shaped groove, the convenience of inserting the linkage block into the linkage groove is improved.

[0018] In one specific implementation, a guide rail is provided on the outer wall of the hopper, and a mounting plate is provided on the guide rail that slides along the axial direction of the reciprocating screw. The linear drive mechanism is mounted on the mounting plate.

[0019] By adopting the above technical solution, the linear drive mechanism is mounted on the mounting plate, and the sliding of the mounting plate on the guide rail improves the convenience of the linear drive mechanism sliding with the rotating disk.

[0020] In one specific implementation, the linear drive mechanism includes a drive member, a sliding block, and a fixed block. The fixed block is fixedly mounted on the mounting plate. The edge of the drive disk is inserted into the fixed block and slidably mounted therewith. The sliding block is slidably mounted on the mounting plate. The edge of the rotating disk is inserted into the fixed block and slidably mounted therewith. The drive member is mounted on the mounting plate and is used to drive the rotating disk closer to or away from the drive disk via the sliding block.

[0021] By adopting the above technical solution, when the control disc drives the drive disc to rotate, the drive component drives the sliding block to slide towards the fixed block, and the sliding block pushes the disc to move towards the drive disc, thereby achieving stable driving of the disc; the setting of the fixed block facilitates the drive disc to drive the support plate to slide.

[0022] In one specific implementation, the driving component includes a drive motor and a drive screw. The drive motor is fixedly mounted on the mounting plate, and the drive screw is coaxially fixed on the output shaft of the drive motor and arranged along the axial direction of the reciprocating screw. The drive screw passes through the sliding block and is threadedly connected to the sliding block.

[0023] By adopting the above technical solution, the sliding block is driven to move closer to or away from the fixed block by the forward and reverse rotation of the drive motor, so that the rotating disk can be driven or disengaged from the drive disk, thereby improving the stability of the connection and disengagement between the rotating disk and the drive disk.

[0024] In one specific implementation, a guide rod is fixed on the fixed block and arranged parallel to the drive screw. The guide rod passes through the sliding block and is slidably connected to the sliding block.

[0025] By adopting the above technical solution and setting guide rods, the stability of the sliding block sliding on the mounting plate is improved.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. When the silo is working, the drive unit drives two feeding rollers to rotate, sending the material in the silo to the discharge port. When large pieces of material overlap the two feeding rollers, causing material to pile up, the control unit controls the connecting unit to connect with the feeding rollers. The feeding rollers drive the crushing claws to slide along the axial direction of the feeding rollers through the connecting unit. At the same time, the feeding rollers drive the crushing claws to rotate through the transmission unit, crushing the large pieces of material overlapping the feeding rollers. This effectively avoids the accumulation of material in the silo. Compared with the anti-piling method of vibrators, the solution of this application is less likely to cause impact on the silo structure, thereby improving the service life of the silo.

[0028] 2. When material accumulates in the hopper, the control unit controls the rotating disk to drive the drive disk to rotate. While rotating, the drive disk slides under the guidance of the reciprocating screw. The drive disk drives the rotating disk to move. The rotating disk drives the transmission ring to slide on the feeding roller through the connecting rod, increasing the working range of the crushing claw and making the crushing claw more reliable in crushing large pieces of material.

Detailed Implementation

[0039] The following is in conjunction with the appendix Figure 1-9 This application will be described in further detail.

[0040] This application discloses a device for preventing material accumulation in the feed roller hopper of a hammer crusher.

[0041] Reference Figure 1 , Figure 2A hammer crusher feed roller hopper anti-stacking device includes a hopper 1, two feed rollers 2, a drive unit 3, crushing claws 4, a transmission unit 5, a connecting unit 6, and a control unit 7. The hopper 1 is fixedly installed on the hammer crusher 9 by a bracket. The discharge port of the hopper 1 is connected to the feed port of the hammer crusher 9. The material enters the hopper 1 from the feed port at the top of the hopper 1. The two feed rollers 2 are placed horizontally in parallel inside the hopper 1 and are rotated with the hopper 1 by a rotating shaft. The material is squeezed into the discharge port of the hopper 1 by the two feed rollers 2. The crushing claws 4 correspond one-to-one with the feed rollers 2. Each crushing claw 4 is connected to the feed roller 2 through the transmission unit 5. The feed roller 2 can drive the crushing claw 4 to rotate through the transmission unit 5. The crushing claw 4 can slide along the axial direction of the feed roller 2 with the help of the transmission unit 5. Each crushing claw 4 extends radially along the feed roller 2. The length of the crushing claw 4 can be set according to the distance between the two feed rollers 2 and the maximum particle size of the large material.

[0042] Reference Figure 1 , Figure 2 The connecting unit 6 is installed on the hopper 1 and corresponds one-to-one with the feeding rollers 2. Each feeding roller 2 drives the crushing claw 4 to reciprocate on the feeding roller 2 through the connecting unit 6. Initially, the crushing claw 4 is located at the end of the feeding roller 2 to reduce the impact of the crushing claw 4 on the feeding between the two feeding rollers 2. The control unit 7 is used to control the connection and disconnection between the connecting unit 6 and the feeding roller 2, so that the crushing claw 4 only slides along the axial direction of the feeding roller 2 to crush large pieces of material when there is material accumulation in the hopper 1. The drive unit 3 is used to drive the two feeding rollers 2 to rotate relative to each other.

[0043] When the silo 1 is working, the drive unit 3 drives the two feeding rollers 2 to rotate, sending the material in the silo 1 to the discharge port. When large pieces of material overlap the two feeding rollers 2, causing material to pile up, the control unit 7 controls the connecting unit 6 to connect with the feeding rollers 2. The feeding rollers 2 drive the crushing claws 4 to slide along the axial direction of the feeding rollers 2 through the connecting unit 6. At the same time, the feeding rollers 2 drive the crushing claws 4 to rotate through the transmission unit 5, crushing the large pieces of material overlapping the feeding rollers 2, effectively preventing the material from piling up in the silo 1. Compared with the anti-piling method of the vibrator, the solution of this application is less likely to cause impact on the structure of the silo 1, thereby improving the service life of the silo 1.

[0044] Reference Figure 3 In this embodiment, the drive unit 3 includes a rotary motor 31 and two transmission gears 32. Each transmission gear 32 corresponds to a feeding roller 2 and is coaxially fixed on the rotating shaft of the feeding roller 2. The two transmission gears 32 mesh with each other. The output shaft of the rotary motor 31 is coaxially fixedly connected to one of the transmission gears 32. The rotary motor 31 drives the two transmission gears 32 to rotate, thereby driving the two feeding rollers 2 to rotate relative to each other, thus extruding and feeding the material in the hopper 1.

[0045] Reference Figure 3 , Figure 4 In this embodiment, the transmission unit 5 includes a transmission ring 51. The feed roller 2 has a polygonal cross-section, but in this embodiment, the cross-section is a regular hexagon. The transmission ring 51 is slidably sleeved on the feed roller 2 and engages with it. The crushing claw 4 is fixedly mounted on the transmission ring 51. When large pieces of material overlap the two feed rollers 2, their position is uncertain. By driving the crushing claw 4 to slide along the axial direction of the feed roller 2 through the transmission ring 51, the processing range of the crushing claw 4 can be increased, thereby improving the reliability of the crushing claw 4 in crushing large pieces of material. Through the cooperation between the transmission ring 51 and the feed roller 2, the crushing claw 4 can slide along the feed roller 2 while rotating with it, improving the convenience of movement and rotation of the crushing claw 4.

[0046] Reference Figure 3 , Figure 4 In this embodiment, the connecting unit 6 includes a connecting rod 61, a rotating disk 62, and a reciprocating screw 63. A support plate 64 is fixedly provided on the outer wall of the hopper 1. Each feeding roller 2 is connected to the hopper 1 through a rotating support member 65. In this embodiment, the rotating support member 65 includes a support disk 651, which is disposed at one end of the feeding roller 2. The rotating shaft of the feeding roller 2 is coaxially and fixedly connected to the support disk 651.

[0047] Reference Figure 4 , Figure 5 The support plate 651 is embedded in the wall of the hopper 1 and is rotatably connected to the hopper 1. A limiting ring 652 is provided on the peripheral side wall of the support plate 651. The limiting ring 652 is embedded in the hopper 1 and is rotatably connected to the hopper 1. By setting the limiting ring 652, axial displacement of the support plate 651 during rotation can be effectively avoided.

[0048] Reference Figure 3 , Figure 4 There are two connecting rods 61, which are opposite each other along the circumference of the rotating disk 62. Each connecting rod 61 passes through the support disk 651 and is slidably connected to the support disk 651. One end of the connecting rod 61 passing through the support disk 651 is fixedly connected to the transmission ring 51, and the other end is fixedly connected to the rotating disk 62, so that the axis of the rotating disk 62 is collinear with the rotation axis of the feeding roller 2. The reciprocating screw 63 is fixedly mounted on the support plate 64, so that the axis of the reciprocating screw 63 is collinear with the axis of the feeding roller 2. The reciprocating screw 63 passes through the rotating disk 62 and is rotatably mounted on the rotating disk 62.

[0049] Reference Figure 3 , Figure 6A drive disk 66 is threaded onto the reciprocating screw 63. The drive disk 66 is located on the side of the rotating disk 62 away from the hopper 1. The control unit 7 can control the rotating disk 62 to drive the drive disk 66 to rotate. In this embodiment, the control unit 7 includes a linear drive mechanism 71 and a connecting block 72. There are two connecting blocks 72, which are arranged opposite each other along the circumference of the rotating disk 62. A connecting groove 73 is provided on the side wall of the drive disk 66 opposite to the rotating disk 62 for the connecting block 72 to be inserted. The connecting groove 73 corresponds one-to-one with the connecting block 72.

[0050] Reference Figure 7 , Figure 8 The linkage groove 73 is an arc-shaped groove, and the center of the trajectory of the linkage groove 73 is collinear with the axis of the drive disk 66.

[0051] Reference Figure 3 , Figure 7 One end of the linkage block 72, away from the drive disk 66, extends outward to form an end cap 721. A telescopic spring 74 is provided on the rotating disk 62, corresponding one-to-one with the linkage block 72 and sleeved on it. One end of the telescopic spring 74 is fixedly connected to the rotating disk 62, and the other end is fixedly connected to the end cap 721. Initially, the telescopic spring 74 applies a spring force to the linkage block 72 in the direction of the drive disk 66. The telescopic spring 74 first pushes the linkage block 72 against the drive disk 66. When the linkage block 72 rotates to the position of the linkage groove 73, the telescopic spring 74 pushes the linkage block 72 into the linkage groove 73, thereby improving the reliability of the linkage block 72's insertion into the linkage groove 73.

[0052] Reference Figure 2 , Figure 9 Two sets of guide rails 81 are fixedly provided on the support plate 64 along the axial direction of the reciprocating screw 63. Each linear drive mechanism 71 corresponds to one set of guide rails 81, and a mounting plate 82 is slidably provided on each set of guide rails 81. In this embodiment, the linear drive mechanism 71 includes a drive component 711, a sliding block 712, and a fixing block 713. The fixing block 713 is fixedly provided on the mounting plate 82. The fixing block 713 has a first limiting groove 714 for the edge of the drive disk 66 to be inserted. The drive disk 66 is rotatably connected to the first limiting groove 714. When the drive disk 66 moves along the reciprocating screw 63, the drive disk 66 can push the fixing block 713 to drive the mounting plate 82 to slide on the guide rails 81. The sliding block 712 is slidably provided on the mounting plate 82. The sliding block 712 has a second limiting groove 715 for the edge of the rotating disk 62 to be inserted. The rotating disk 62 is slidably provided with the second limiting groove 715. The sliding block 712 can drive the rotating disk 62 to slide along its own axial direction.

[0053] Reference Figure 2 , Figure 9In this embodiment, the driving component 711 includes a driving motor 7111 and a driving screw 7112. The driving motor 7111 is fixedly mounted on the mounting plate 82, and the driving screw 7112 is coaxially fixedly mounted on the output shaft of the driving motor 7111. The driving screw 7112 passes through a fixed block 713 and is rotatably connected to the fixed block 713. One end of the driving screw 7112 passing through the fixed block 713 passes through a sliding block 712 and is threadedly connected to the sliding block 712. The sliding block 712 slides on the support plate 64 by rotating the driving screw 7112 in both forward and reverse directions. A guide rod 7113 is fixedly mounted on the support plate 64. The guide rod 7113 is fixedly mounted to the fixed block 713, passes through the sliding block 712, and is slidably connected to the sliding block 712. The guide rod 7113 is parallel to the driving screw 7112. The guide rod 7113 is used to improve the stability of the sliding block 712 on the mounting plate 82.

[0054] When material accumulates in hopper 1, the drive motor 7111 drives the drive screw 7112 to rotate. The drive screw 7112, through the sliding block 712, drives the rotating disk 62 to move towards the drive disk 66. As the rotating disk 62 approaches the drive disk 66, the telescopic spring 74 pulls the connecting block 72 into the connecting groove 73. When the rotating disk 62 drives the connecting block 72 to abut against the side wall of the connecting groove 73, the rotating disk 62 drives the drive disk 66 to rotate. While rotating, the drive disk 66 slides under the guidance of the reciprocating screw 63. The drive disk 66, through the fixing block 713, drives the mounting plate 82 to slide along the guide rail 81. At the same time, the drive disk 66 drives the rotating disk 62 to slide. The rotating disk 62, through the connecting rod 61, pushes the crushing claw 4 on the transmission ring 51 to slide axially along the feeding roller 2, thereby increasing the working range of the crushing claw 4 and improving the anti-accumulation effect of hopper 1. The reciprocating screw 63 enables the crushing claw 4 to perform continuous crushing work.

[0055] After the material processing in the hopper 1 is completed, the crushing claw 4 moves to one end of the feeding roller 2. Then, the drive motor 7111 drives the drive screw 7112 to reverse. The drive screw 7112 drives the rotating disk 62 away from the drive disk 66 through the sliding block 712. The rotating disk 62 pulls the connecting block 72 out of the connecting groove 73, so that the connecting block 72 is disengaged from the drive disk 66. At this time, the drive disk 66 remains stationary, and the rotating disk 62 continues to rotate under the drive of the feeding roller 2, thereby realizing the connection and disengagement between the rotating disk 62 and the drive disk 66, improving the convenience of the crushing claw 4 for material processing.

[0056] The implementation principle of the anti-stacking device for the feed roller hopper of a hammer crusher in this embodiment is as follows: When the hopper 1 is working, the rotating motor 31 drives the two feed rollers 2 to rotate through two transmission gears 32, sending the material in the hopper 1 to the discharge port. When large pieces of material overlap the two feed rollers 2, causing material to accumulate, the driving motor 7111 drives the driving screw 7112 to rotate. The driving screw 7112 drives the rotating disk 62 to move towards the driving disk 66 through the sliding block 712. As the rotating disk 62 moves closer to the driving disk 66, the extension spring 74 pulls the connecting block 72 to insert into the connecting groove 73. When the rotating disk 62 drives the connecting block 72 to connect with the connecting groove 73, the material accumulates. When the side wall of the moving groove 73 abuts, the rotating disk 62 drives the driving disk 66 to rotate. While the driving disk 66 rotates, it slides under the guidance of the reciprocating screw 63. The driving disk 66 drives the mounting plate 82 to slide along the guide rail 81 through the fixed block 713. At the same time, the driving disk 66 drives the rotating disk 62 to slide. The rotating disk 62 pushes the crushing claw 4 on the transmission ring 51 to slide along the axial direction of the feeding roller 2 through the connecting rod 61, crushing the large pieces of material overlapping on the feeding roller 2. This effectively avoids the accumulation of material in the silo 1. Compared with the anti-stacking method of the vibrator, the solution of this application is less likely to cause impact on the structure of the silo 1, thereby improving the service life of the silo 1.

[0057] 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.
