Coal crushing device

Technical field

The utility model relates to coal apparatus fields, and in particular to a kind of coal crushing device.

Background technique

Crushing device is the machinery that large-sized solid material is crushed to desired size, and material is mainly carried out crushing side Just it transports, is widely used in the multiple fields such as mine, building.

In mining equiment, when especially thoroughly being crushed to big blocky coal, traditional crushing device often uses big function Rate motor drive, and heavy-duty motor operation rotation in, not only noise is big, and generate vibration also seriously affect device Service life, and damping device is used to carry out the damping of vertical direction using elastic element mostly, but it is broken when the vibration that generates Direction is unpredictable, lacks the damping in other directions；In addition, in shattering process, since motor drives breaker roll rotation to hold very much Easily coal fragment is sputtered from discharge outlet, cause the accident generation, and some crushing devices use special feeding structure, to coal Charcoal fragment is stopped, and avoids the splashing of coal pieces, but the dust that broken coal generates still can carry out from feed inlet It overflows, influences the working environment of workers.

Utility model content

The utility model provides a kind of coal crushing device, and structure is simple, not only realizes the efficiency crushing of coal, but also Sealing when realizing broken, avoids the dust of splashing and the generation of coal from overflowing, while realizing the damping to device, service life It is longer.

To achieve the above object, this coal crushing device includes broken main tank, grinding device and upper cover plate, further includes close Seal apparatus, damping device,

The broken main tank upper end installation upper cover plate, lower end setting damping device and discharge port；The upper cover plate upper end is set Feed inlet is set, the sealing device is two groups, and is symmetrical set at feed inlet, and the sealing device includes sleeve, leads Column, compressed spring and baffle；Described baffle one end is hingedly mounted on upper cover plate lower end, the other end is located at below discharge port, described Sleeve is mounted on upper cover plate, the guide post upper end is slidably mounted in sleeve, lower end passes through upper cover plate and by connecting line with Connection in the middle part of baffle, the compressed spring is sleeved on guide post and one end is contacted with guide post upper-end contact, the other end with upper cover plate；

Crushing device is set in the broken main tank, and the crushing device includes main broken wheel and secondary broken wheel, the master Broken wheel is two and is symmetrical set in broken main tank, under the secondary broken wheel setting is between the main broken wheel of a pair Side, the grinding device are arranged below crushing device；

The damping device includes the first spring, sliding rail and support device；The sliding rail is set on the base, described broken Main tank lower end horizontally slips installation on the slide rail, and passes through a pair of first spring and base contacts, institute at left and right sides of broken main tank It states the first spring and is in compressive state, support device is arranged in the pedestal lower end.
