Description

Technical Field

[0001] The utility model belongs to the technical field of raw coal crushing, in particular to a raw coal crushing device. Background Art

[0002] Raw coal refers to the product produced by coal mines that has not been washed, screened or processed but only manually picked out gangue and debris. It includes natural coke and inferior coal, but does not include low calorific value coal (such as stone coal, peat, oil shale, etc.). Raw coal can be divided into three categories according to its origin, namely humic coal, saprophytic coal and humic saprophytic coal. It can be divided into peat, lignite, bituminous coal and anthracite according to its degree of carbonization.

[0003] In the process of crushing raw coal using a raw coal crusher, dust will be generated. In order to protect the health of the workers, the dust needs to be contained. However, in the existing technology, most raw coal crushers contain dust by adding a cover to the raw coal crusher. This requires the workers to repeatedly open and close the cover when adding materials, which not only increases the workload of the workers, but also reduces the crushing efficiency of the raw coal. Utility Model Content

[0004] The utility model aims to provide a raw coal crushing device to solve the problems raised in the background technology.

[0032] The utility model is provided with a dust component 2. When in use, the crusher body 1 is first started, and then the raw coal is put into the feeding port 2012. Due to the weight of the raw coal itself, the two dust plates 202 are rotated away from each other in the box body 2011 through the rotating shaft, so that the limit block 206 squeezes the inner wall of the limit groove 205, and the two limit blocks 206 slide away from each other in the limit groove 205, so that the movable plate 204 slides downward in the movable groove 203 through the elastic component 3, so that the raw coal can fall into the feeding port of the crusher body 1 through the gap between the two dust plates 202, and the raw coal is crushed by the crushing mechanism on the crusher body 1. The utility model is simple to operate, reasonable in layout, and has a good dust removal effect.

[0033] As a preferred embodiment, the dust plate 202 is inclined, and the high end of the dust plate 202 is arranged close to the feeding port 2012, and the low end of the dust plate 202 is arranged away from the feeding port 2012. In order to facilitate the weight of the raw coal, the two dust plates 202 rotate in opposite directions in the box body 2011 through the rotating shaft, so that the raw coal can fall into the box body 2011 from the gap between the two dust plates 202.

[0034] As a preferred embodiment, the movable groove 203 is in a right-angled trapezoidal structure, the size of the opposite side of the two movable grooves 203 is larger than the size of the opposite side of the two movable grooves 203, and the inclined surface of the movable groove 203 is arranged away from the feeding port 2012. This prevents the raw coal falling into the box body 2011 from falling on the movable groove 203, resulting in unbroken raw coal remaining in the movable groove 203, thereby affecting the use effect of the utility model.

[0035] As a preferred embodiment, the limiting groove 205 is V-shaped, and the tip of the limiting groove 205 is arranged away from the feeding port 2012, so that the limiting block 206 can squeeze the inner wall of the limiting groove 205, so that the two limiting blocks 206 can slide away from each other in the limiting groove 205, and the two dust plates 202 can rotate away from each other in the box body 2011 through the rotating shaft.

[0036] As a preferred implementation scheme, the elastic component 3 includes a fixed block 301, a spring slot 302, a sliding block 303 and a return spring 304; the two fixed blocks 301 are symmetrically fixed in the movable slot 203; a spring slot 302 is provided on the side of the fixed block 301 close to the movable plate 204; the sliding block 303 is slidably arranged in the spring slot 302, and the end of the sliding block 303 passes through the spring slot 302 and is fixedly connected to the movable plate 204; the two ends of the return spring 304 are respectively fixedly connected to the inner wall of the spring slot 302 and the sliding block 303; wherein, the bottom surface of the fixed block 301 is set to an inclined surface, and the inclined surface is fixed on the inclined surface of the movable slot 203; when the opposite ends of the two dust-absorbing plates 202 are in contact, the return spring 304 returns to its original shape.

[0037] The utility model sets a fixed block 301, a spring groove 302, a sliding block 303 and a return spring 304. When the movable plate 204 slides downward in the movable groove 203, the sliding block 303 will slide downward in the spring groove 302, so that the return spring 304 is forced to shrink. The dust plate 202 can automatically rotate to its original position according to the weight of the raw coal. While removing the dust, it is also convenient to feed the raw coal into the feeding port 2012 next time, thereby improving the practicality of the utility model.

[0038] The crusher body 1 is a conventional instrument. Its working principle, size and model are irrelevant to the problem solved by the present application, so no further description will be given. The control method of the present invention is controlled by a controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.

[0039] How it works

[0040] When the raw coal crushing device is used, first, the crusher body 1 is started, and then the raw coal is put into the feeding port 2012. Due to the weight of the raw coal itself, the two dust plates 202 are rotated away from each other in the box body 2011 through the rotating shaft, so that the limit block 206 squeezes the inner wall of the limit groove 205, and the two limit blocks 206 slide away from each other in the limit groove 205, so that the movable plate 204 slides downward in the movable groove 203, and the sliding block 303 slides downward in the spring groove 302, so that the return spring 304 is forced to contract, so that the raw coal can fall from the gap between the two dust plates 202 into the feeding port of the crusher body 1, and is crushed. The crushing mechanism on the machine body 1 crushes the raw coal, and as the raw coal falls into the box body 2011, the gravity on the dust plate 202 will gradually decrease, so that the return spring 304 will gradually stretch, so that the sliding block 303 will slide upward in the spring groove 302, and the movable plate 204 will slide upward in the movable groove 203, so that the inner wall of the limit groove 205 will squeeze the limit block 206, so that the two limit blocks 206 will slide relatively in the limit groove 205, and the two dust plates 202 will rotate relatively in the box body 2011 through the rotating shaft until the dust plate 202 rotates to the original position. At this time, the return spring 304 returns to its original shape, and this is repeated.
