Abstract
Description
Technical Field
[0001] This utility model relates to the field of crusher technology, and in particular to a liner assembly for a toothed roller crusher. Background Technology
[0002] Toothed roller crushers are suitable for industries such as coal, metallurgy, mining, chemical, and building materials. Their working principle is relatively simple. The electric motor drives the two toothed rollers to rotate in opposite directions after the power is reduced by the reducer. When the material enters the crushing chamber of the machine body from the inlet, the material is crushed by the breaking, shearing, and stretching action of the toothed roller teeth and then discharged from the discharge port. The main function of the liner is to protect the machine casing from wear.
[0003] The common installation of liner plates often uses multiple bolts for fixing, which is time-consuming and labor-intensive. This not only results in low efficiency, but also makes the bolt removal process cumbersome when the liner plate needs to be replaced or the equipment needs to be repaired, especially when the bolts are rusted or damaged, making removal even more difficult. Utility Model Content
[0004] The purpose of this utility model is to solve the shortcomings of the existing technology, which has low efficiency and the bolt disassembly process is also cumbersome when it is necessary to replace the liner or repair the equipment, especially when the bolt is rusted or damaged, making disassembly even more difficult. Therefore, a liner assembly for a toothed roller crusher is proposed.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A liner assembly for a toothed roller crusher, comprising a body;
[0007] Two liners are used to protect the inner wall of the crushing chamber of the machine body. The two liners are located on opposite sides of the inner wall of the crushing chamber of the machine body.
[0008] The mounting mechanism is used to fix the liner to the inner wall of the machine body. The mounting mechanism is set on the outside of the machine body and includes two mounting plates, which are respectively located on both sides of the machine body. The surface of the liner is provided with multiple fixing holes. Multiple fixing rods are fixedly installed on one side of the mounting plate, and the multiple fixing rods slide through the machine body and cooperate with the multiple fixing holes on the same side.
[0009] In one possible design, the mounting mechanism further includes a bidirectional threaded rod and a limiting rod. A first bracket is fixedly installed on one side of the machine body, and the bidirectional threaded rod rotatably passes through the first bracket. Two mounting plates are respectively threaded onto both ends of the outer wall of the bidirectional threaded rod. A second bracket is fixedly installed on the other side of the machine body, and the limiting rod is fixedly passed through the second bracket. Both mounting plates are slidably sleeved on the outer wall of the limiting rod.
[0010] In one possible design, one of the mounting plates has an inner cavity, and a rod is slidably disposed inside the inner cavity. A slot is provided on one side of the outer wall of the limiting rod, and one end of the rod slides through the mounting plate and engages with the slot.
[0011] In one possible design, a compression spring is provided inside the cavity, with its two ends fixedly disposed at one end of the insert rod and one side of the inner wall of the cavity, respectively.
[0012] In one possible design, a pull plate is fixedly provided on the outer wall of the insertion rod, and the pull plate slides through to the outside of the mounting plate.
[0013] In one possible design, limit plates are fixedly installed at both ends of the inner walls on both sides of the crushing chamber of the machine body, and insert plates are provided on both sides of the liner, with the two insert plates cooperating with the two limit plates on the same side.
[0014] In one possible design, the limiting plate is L-shaped.
[0015] In one possible design, a limiting block is fixedly provided at the bottom of the inner wall of the limiting plate, and a notch is provided at the bottom of the insert plate, which cooperates with the adjacent limiting block.
[0016] In this application, during actual use, both liner plates are inserted between the two limiting plates on both sides through the side insert plates and abut against the top of the limiting blocks. Then, the double-threaded rod is rotated, which will drive the two mounting plates to move towards each other. The mounting plates drive the fixing rod to move, so that the fixing rod passes through the crushing chamber and extends into the interior of the fixing hole, thereby fixing the liner plate. When the mounting plate moves to the designated position, the internal insert rod will be reset by the compression spring, so that one end of it passes through the mounting plate and is locked into the interior of the slot. At this time, the mounting plate will be unable to move. When it is necessary to remove the liner plate for replacement, simply move the insert rod to disengage it from the interior of the slot, and then rotate the double-threaded rod in the opposite direction.
[0017] In this utility model, the liner assembly of the toothed roller crusher can achieve quick installation and removal of the liner on the machine body through the installation mechanism, without the need for complex processes such as bolts or welding, which greatly improves the installation efficiency and convenience.
[0018] In this utility model, the liner assembly of the toothed roller crusher, through the insertion rod and the limiting plate, can further limit the movement range of the liner, improve the stability and fixing effect of the liner, and the automatic locking of the mounting plate further improves the stability and reliability of the installation mechanism.
[0019] In this invention, during use, the liner plate is simply inserted into the inner wall of the crushing chamber. Then, rotating the bidirectional threaded rod will move multiple fixing rods so that they are inserted into the corresponding fixing holes for installation and fixation. Rotating the bidirectional threaded rod to the designated position will automatically fix it, thus avoiding the need for manual tightening of bolts for sequential fixing, reducing labor and improving efficiency.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0025] Example 1
[0026] Reference Figure 1-2 A liner assembly includes: a body 1, two liners 3, and an installation mechanism. The body 1 is the main structure of the crusher, and its interior has a crushing chamber. The two liners 3 are located on opposite inner walls of the crushing chamber of the body 1, respectively, to protect the inner wall of the body 1 from impact and wear during material crushing.
[0027] The mounting mechanism is used to fix the liner 3 to the inner wall of the body 1. The mounting mechanism is located on the outside of the body 1 and specifically includes two mounting plates 6, a bidirectional threaded rod 2, a limiting rod 4, and related connecting and fixing components. The two mounting plates 6 are located on opposite sides of the body 1, maintaining a certain distance from the outer wall of the body 1. Multiple fixing holes 9 are formed on the surface of the liner 3, which are used to engage with fixing rods 11 on the mounting plates 6. Multiple fixing rods 11 are fixedly installed on one side of the mounting plate 6. These fixing rods 11 slide through the body 1 and engage with the multiple fixing holes 9 on the same side, thereby fixing the liner 3 to the inner wall of the body 1.
[0028] Furthermore, a first bracket 16 is fixedly installed on one side of the machine body 1, and a bidirectional threaded rod 2 rotatably passes through the first bracket 16. Two mounting plates 6 are respectively threaded onto both ends of the outer wall of the bidirectional threaded rod 2. When the bidirectional threaded rod 2 rotates, the two mounting plates 6 move along the bidirectional threaded rod 2, causing the fixing rod 11 to be inserted into the fixing hole 9. A second bracket 17 is fixedly installed on the other side of the machine body 1, and a limiting rod 4 is fixedly passed through the second bracket 17. Both mounting plates 6 are slidably sleeved on the outer wall of the limiting rod 4 to limit the offset of the mounting plates 6 during movement and ensure the stability and accuracy of the mounting plates 6.
[0029] To further enhance the stability and reliability of the mounting mechanism, one of the mounting plates 6 has an inner cavity 14, within which a rod 13 is slidably mounted. A slot 12 is formed on one side of the outer wall of the limiting rod 4, and one end of the rod 13 slides through the mounting plate 6 and engages with the slot 12. When the mounting plate 6 is adjusted to the appropriate position, the rod 13 automatically inserts into the slot 12 under the action of the compression spring 15, thereby locking the position of the mounting plate 6 and preventing it from moving.
[0030] Reference Figure 2 To further improve the stability and fixation of the liner 3, limit plates 7 are fixedly installed at both ends of the inner walls on both sides of the crushing chamber of the machine body 1, and insert plates 10 are installed on both sides of the liner 3. The two insert plates 10 cooperate with the two limit plates 7 on the same side to further fix the position of the liner 3 through insertion. The limit plates 7 are L-shaped, which can better restrict the movement of the liner 3. A limit block 8 is fixedly installed at the bottom of the inner wall of the limit plate 7, and a notch is opened at the bottom of the insert plate 10, and the notch cooperates with the adjacent limit block 8. Through the cooperation of the limit block 8 and the notch, the liner 3 can be further placed.
[0031] This application can be used in the field of crushers, or in other fields applicable to this application.
[0032] Example 2
[0033] refer to Figure 3An improvement based on Embodiment 1: A liner assembly for a toothed roller crusher, applied in the crusher field, wherein two liners 3 are inserted between two limiting plates 7 on both sides via side insert plates 10 and abut against the top of the limiting block 8. Then, the bidirectional threaded rod 2 is rotated, which will drive the two mounting plates 6 to move towards each other. The mounting plates 6 drive the fixing rod 11 to move, so that the fixing rod 11 passes through the crushing chamber 1 and extends into the interior of the fixing hole 9, thereby fixing the liner 3. When the mounting plate 6 moves to the designated position, the insert rod 13 inside will be reset by the compression spring 15, so that one end of it passes through the mounting plate 6 and is locked into the interior of the slot 12. At this time, the mounting plate 6 will be unable to move. When the liner 3 needs to be removed for replacement, simply move the insert rod 13 to disengage it from the interior of the slot 12, and then rotate the bidirectional threaded rod 2 in the opposite direction.
