Technical Field

[0001] The utility model relates to the technical field of underground special operation equipment, in particular to a 10-ton crusher for underground special operations. Background Art

[0002] At present, when carrying out special operations underground, it is necessary to use a specially developed 10-ton small crusher, which has the characteristics of small size, light weight, easy operation and strong passability, and can meet the needs of complex underground working environments.

[0003] For example, the patent application number 201721379025.2 discloses a coal mine underground crusher, which is a traditional underground special operation 10-ton crusher, which mainly includes a breaker, a breaker connecting plate, a lower cantilever cylinder, a lower cantilever, a lower cantilever connecting plate, an upper cantilever, an upper cantilever cylinder, a body, a transmission device, an operating table and an operating cab, etc. However, the existing crushers of this type have the following problems in actual use:

[0004] First, due to the harsh underground working environment, the breaker hammer is severely worn during long-term high-load operation and needs to be replaced frequently. However, traditional breaker hammers are often installed with bolts and mechanical arms. This installation method makes the replacement process of the breaker hammer cumbersome, time-consuming and labor-intensive, and requires the use of professional tools to operate, which leads to low replacement efficiency.

[0005] Secondly, this type of traditional underground crusher does not have the function of dust absorption. During the crushing operation, it is impossible to deal with the raised dust to a certain extent, resulting in serious dust pollution underground and a major safety hazard. Utility Model Content

[0006] In view of the deficiencies in the prior art, the utility model provides a 10-ton crusher for special underground operations, which effectively solves the problem that the replacement process of the existing 10-ton crusher for special underground operations is cumbersome, time-consuming and labor-intensive, and requires the use of professional tools for operation, which leads to low replacement efficiency. It also solves the problem that during the crushing operation, the dust raised cannot be processed to a certain extent, resulting in serious dust pollution underground and a major safety hazard.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] A 10-ton crusher for special underground operations comprises a connecting shell installed on a mechanical arm of the crusher, wherein a conical crushing hammer is fixed in the connecting shell through a locking mechanism, wherein the locking mechanism comprises three threaded locking components distributed at equal distances and a synchronous control component, wherein the setting of the locking mechanism makes it more convenient and quick to replace the crushing hammer, saves time and effort, and does not require the use of professional tools for operation, thereby improving replacement efficiency;

[0009] A dust suction mechanism is provided outside the connecting shell, and the dust suction mechanism includes a dust suction box fixedly connected to the front outer wall of the connecting shell, a dust suction pipe fixedly connected to the top of the dust suction box, a dust suction hood fixedly connected to the bottom of the dust suction pipe, a sealed drawer installed in the dust suction box, a dust filter net fixedly installed in the sealed drawer and a dust suction fan fixedly installed at the bottom of the dust suction box. Therefore, the dust suction mechanism has a dust suction function and can process the raised dust to a certain extent during the crushing operation, thereby reducing the pollution of dust underground and reducing safety hazards.

[0010] Preferably, the three threaded locking assemblies each include a slide groove opened on the inner wall at the rear side of the connecting shell, a bidirectional screw rotatably installed in the slide groove, two centering slide rods symmetrically threadedly connected to the two opposite threaded ends of the bidirectional screw, and two C-shaped locking claws symmetrically welded to the outer wall of one adjacent side of the two centering slide rods.

[0011] Preferably, the outer walls of the two centering slide bars are slidably connected to the inner wall of the slide groove, which can ensure that the two centering slide bars can perform linear motion.

[0012] Preferably, the synchronous control component includes a bracket welded to the side wall of the connecting shell, a transmission shaft rotatably mounted on the bracket, three worms fixedly mounted on the transmission shaft and distributed at equal distances, and three worm wheels fixedly mounted on one end of the three bidirectional screws in sequence. The three worms are respectively meshed with the three worm wheels to facilitate the synchronous rotation of the three bidirectional screws.

[0013] Preferably, a hand wheel is fixedly connected to the top outer wall of the transmission shaft, which can facilitate workers to better manually control the rotation of the transmission shaft.

DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0026] Furthermore, the three thread locking components each include a slide groove 10 provided on the inner wall at the rear of the connecting shell 2, a bidirectional screw 11 rotatably mounted in the slide groove 10, two centering slide bars 12 symmetrically threadedly connected to two opposite threaded ends of the bidirectional screw 11, and two C-shaped locking claws 13 symmetrically welded to the outer walls of the adjacent sides of the two centering slide bars 12, the outer walls of the two centering slide bars 12 are slidably connected to the inner wall of the slide groove 10.

[0027] Furthermore, the synchronous control assembly includes a bracket 14 welded to the side wall of the connecting shell 2, a transmission shaft 15 rotatably mounted on the bracket 14, three worms 16 fixedly mounted on the transmission shaft 15 and distributed at equal distances, and three worm wheels 17 fixedly mounted on one end of the three bidirectional screws 11 in sequence, the three worms 16 are respectively meshed with the three worm wheels 17, and a hand wheel 18 is fixedly connected to the outer wall of the top end of the transmission shaft 15;

[0028] During the specific implementation of this embodiment: the three worms 16 on the transmission shaft 15 are controlled to rotate by rotating the hand wheel 18 forwardly, and then the three worm wheels 17 meshing with the three worms 16 will synchronously control the three bidirectional screws 11 to rotate forwardly. Under the limit of the three slide grooves 10, the three groups of C-shaped locking claws 13 will all be aligned and close to jointly lock the conical breaker 3, so that the quick installation can be completed. Similarly, during the subsequent disassembly, it is only necessary to rotate the hand wheel 18 in the opposite direction to make the three bidirectional screws 11 rotate in the opposite direction, so that the three groups of C-shaped locking claws 13 will all move away from each other and unlock together, so that the quick disassembly can be completed. This makes the replacement of the breaker more convenient and quick, saves time and effort, and does not require the use of professional tools for operation, which is conducive to improving the replacement efficiency.

[0032] Dust filter 8 and dust suction fan 9: The dust filter 8 is fixedly installed in the sealed drawer 7, and the dust suction fan 9 is fixedly installed at the bottom of the dust suction box 4;

[0033] During the specific implementation of this embodiment, the suction force generated by the dust suction fan 9 during operation can allow the dust generated during the underground crushing process to be sucked into the dust suction box 4 from the dust suction hood 6 through the dust suction pipe 5. The dust that finally enters will be filtered and intercepted by the dust filter 8 and collected in the sealed drawer 7. In this way, the dust suction function is provided, and the dust raised can be processed to a certain extent during the crushing operation, thereby reducing the pollution of underground dust and reducing safety hazards.
