Description

Technical Field

[0001] The utility model belongs to the technical field of crushing, in particular to a block crushing device for limestone powder production. Background Art

[0002] When producing limestone powder, lump crushing is the first step. The crusher breaks the large lumps of material into a fineness suitable for grinding, laying the foundation for the subsequent grinding process. The mined limestone raw materials may be several meters in size. In order to meet the feeding requirements of different grinding mills, it is usually necessary to crush them into tens of millimeters. First, a jaw crusher is used for coarse crushing to break the large lumps into small pieces, and then an impact crusher is used to break them into smaller particles.

[0003] At present, the jaw crusher in the existing technology often adopts a slide to convey materials from top to bottom in an inclined manner. However, the block material is too large, and it is very easy for the large block material above to cover the feed port during the falling process, resulting in the situation that the crushing cannot be carried out effectively. Manual hammering is required to carry out the crushing operation, which undoubtedly affects the work efficiency and is not conducive to the use of the coherent crushing operation.

[0004] In order to solve the above problems, the present application proposes a block crushing device for limestone powder production. Utility Model Content

[0005] The purpose of the utility model is to provide a block crushing device for limestone powder production, which solves the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0007] The utility model is a block crushing device for limestone powder production, comprising a jaw crusher, side seats are provided on both sides of the jaw crusher, one side of the side seat is provided with a curtain for preventing finely crushed materials from scattering outward, a convex seat is provided above one side of the jaw crusher, a support is provided on one side of the lower end of the convex seat, a rotating shaft is provided on the inner side of the side seat, an adapter block is provided on the outer side of the rotating shaft, a swing block is provided at the lower end of the rotating shaft for hammering block materials to prevent them from covering the feed port and affecting normal crushing operations, a swing rib for connecting the swing block is provided below the adapter block, a boss for installing the swing rib is provided on the adapter block and one side of the swing block, a side plate is provided on one side of the curtain, and a sliding seat for pushing material to prevent blockage is provided inside the convex seat.

[0008] Furthermore, a hammering portion with a sawtooth structure is provided on one side of the swing block, and the hammering portion is used to concentrate the force so that the block is easier to break.

[0009] Furthermore, a top plate for preventing jamming is provided on one side of the slide, and a connecting rod for driving adjacent slides to move back and forth is provided inside the support.

[0010] Furthermore, a paddle is provided inside the opening on one side of the boss to prevent fine materials from entering the interior.

[0011] Furthermore, a protruding plug is provided at one end of the side plate, and a clamping seat for clamping and connecting the plug is provided at one side of the upper end of the side seat.

[0012] Furthermore, a sliding block for fixedly connecting to the connecting rod is provided at the lower end of the sliding seat.

[0013] Furthermore, spiral transmission rods for driving the connecting rod to move are provided inside both ends of the support, and a guide rod mechanism for limiting the connecting rod is provided below the spiral transmission rod.

[0014] The utility model has the following beneficial effects:

[0015] The utility model can drive the swing block to swing up through the rotation of the rotating shaft, hammer the block material blocking the feed inlet, so that part of the area is crushed to adapt to the inlet of the jaw crusher. It can prevent blockage without the need for workers to hammer at the side at risk, effectively ensuring the continuous crushing operation of the jaw crusher, thereby improving its working efficiency and reducing labor output costs;

[0016] The utility model drives the adjacent slide seats to move back and forth by driving the spiral transmission rod through the connecting rod. At this time, the block materials accumulated above the inlet can be pushed out and loosened by using the top plate, thereby preventing a large amount of block materials from piling up to ensure the normal operation of the jaw crusher. The material can be continuously discharged without manual prying, effectively improving the practical performance of the equipment and facilitating its use in large-scale production operations.
