Technical Field
[0001] The utility model relates to the technical field of hammer discs, in particular to an inlaid hammer disc for a crusher. Background Art
[0002] Hammer crushers are suitable for crushing medium-hard materials in industrial sectors such as cement, chemical industry, electric power, and metallurgy, such as limestone, slag, coke, coal, etc. for medium and fine crushing operations. The rotor is one of the important components of a hammer crusher, and the hammer disc is the core component of the rotor. The service life of the rotor mainly depends on the hammer disc. The crusher hammer disc, also known as the rotor disc, is an important component in the hammer crusher, mainly playing roles such as suspending the hammer head, transmitting torque, bearing impact reaction forces, and supporting materials.
[0003] However, when in use, it is impossible to quickly replace the hammer heads on the hammer disc, and the disassembly and replacement are not convenient enough. Therefore, an inlaid hammer disc for a crusher is proposed to overcome the above problems. Summary of the Utility Model
[0004] The purpose of the utility model is to propose an inlaid hammer disc for a crusher. By pressing the pressing block to squeeze the wedge block and the spring, the wedge block and the spring are contracted into the installation hole, releasing the limit on the rectangular block, and then moving the rectangular block to drive the L-shaped connecting column and the insertion rod to move, thereby releasing the limit on the crushing hammer, so that the crushing hammer can be quickly removed.
[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0006] An inlaid hammer disc for a crusher includes a first mounting disc, a second mounting disc, a rectangular block, and a crushing hammer. Four pairs of sliding grooves are evenly opened on the opposite surfaces of the first mounting disc and the second mounting disc.
[0007] A pair of rectangular sliding blocks are respectively arranged on both sides of the rectangular block, and the rectangular sliding blocks are arranged in the sliding grooves.
[0008] Four limiting holes are opened on the first mounting disc, and pressing blocks are arranged in the limiting holes.
[0009] An installation hole corresponding to the limiting hole is opened on one side of the rectangular block. A spring is arranged inside the installation hole. One end of the spring is connected with a wedge block, one end of the wedge block is arranged in the limiting hole. An L-shaped connecting column is arranged on one side of the rectangular block, and an insertion rod is arranged on the upper part of one side of the L-shaped connecting column.
[0010] Preferably, a U-shaped seat is arranged between the first mounting disc and the second mounting disc, and through holes are opened on both sides of the U-shaped seat.
[0011] Preferably, one end of the crushing hammer is arranged inside the U-shaped seat, and a jack corresponding to the through hole is opened at one end of the crushing hammer.
[0012] Preferably, the insertion rod is arranged in the through hole and the insertion hole.
[0013] Preferably, mounting grooves are respectively formed at the upper and lower ends of the rectangular slider.
[0014] Preferably, balls are arranged inside the mounting grooves.
[0015] The utility model has the following beneficial effects:
[0016] 1. By pressing the pressing block, the wedge block and the spring are extruded, so that the wedge block and the spring contract into the mounting hole, and one end of the wedge block is pulled out from the limiting hole, releasing the limit on the rectangular block. Then, the rectangular block is moved to drive the L-shaped connecting column and the insertion rod to move, and the insertion rod is pulled out from the through hole and the insertion hole, releasing the limit on the breaker, so that the breaker can be quickly removed.
[0017] 2. By arranging the balls, when the mounting grooves slide in the sliding grooves, the process is smoother, the movement of the rectangular block is faster, so that the limit on the breaker is released faster, and the disassembly efficiency is increased. Description of the Drawings

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.
[0024] Refer to Figures 1-4, a crusher embedded hammer disc, comprising a first mounting disc 1, a second mounting disc 2, a rectangular block 5 and a crushing hammer 8. Both the first mounting disc 1 and the second mounting disc 2 are circular structures, and four pairs of sliding grooves 3 are evenly arranged on the opposite surfaces of the first mounting disc 1 and the second mounting disc 2.
[0025] A pair of rectangular sliding blocks 503 are respectively arranged on both sides of the rectangular block 5. The rectangular sliding blocks 503 are arranged in the sliding grooves 3. Mounting grooves 504 are respectively opened at the upper and lower ends of the rectangular sliding blocks 503, and balls 505 are arranged inside the mounting grooves 504.
[0026] By arranging the balls 505, when the mounting groove 504 slides in the sliding groove 3, it is more smooth, the movement of the rectangular block 5 is faster, so that the limit on the crushing hammer 8 is released faster, and the disassembly efficiency is increased.
[0027] Four limiting holes 101 are opened on the first mounting disc 1, and pressing blocks 102 are arranged in the limiting holes 101.
[0028] A mounting hole corresponding to the limiting hole 101 is opened on one side of the rectangular block 5. A spring 501 is arranged inside the mounting hole. One end of the spring 501 is connected with a wedge-shaped block 502. One end of the wedge-shaped block 502 is arranged in the limiting hole 101. An L-shaped connecting column 6 is arranged on one side of the rectangular block 5, and a plug rod 7 is arranged on the upper part of one side of the L-shaped connecting column 6.
