[0025] In an embodiment of the utility model, the dust shield plate 5 is fitted with the upper surface of the discharge plate of the crusher body 1, and the dust shield plate 5 is fixedly provided on the side surface of the dust shield plate 5 close to the crushing chamber. An arc-shaped adjusting member 6 is rotatably installed on the rotating portion of the dust shield plate 5, and the arc-shaped adjusting member 6 passes through the strip groove 201 on the upper side plate of the shielding frame 2; the connection of the arc-shaped adjusting member 6 makes it convenient to pull the dust shield plate 5 through the position of the strip groove 201 to flip and move toward the inside of the crusher body 1, and at the same time, with the cooperation of the dust shield plate 5, the connection angle between the dust shield plate 5 and the arc-shaped adjusting member 6 can be automatically adjusted during flipping, so that the feeding port is opened conveniently to add crushed materials inside.

[0026] In an embodiment of the utility model, a limit member 7 is fixedly provided on the upper surface of the shielding frame 2, and the limit member 7 is movably connected to the arc-shaped adjusting member 6; through the setting of the limit member 7, the arc-shaped adjusting member 6 can be limited after being pulled, without affecting the feeding operation.

[0027] In an embodiment of the utility model, the limiting member 7 includes a connecting block 601 combined with the dust shield plate 5, an arc-shaped plate 602 is fixedly provided on the side of the connecting block 601, and a pull block 603 is fixedly provided on the side end of the arc-shaped plate 602 passing through the strip groove 201; the movement of the arc-shaped plate 602 can be conveniently controlled by pulling the pull block 603, and the moving operation is convenient due to the characteristic that the arc-shaped plate 602 is easy to bend and adjust the angle. A canvas layer is provided on the upper surface of the arc-shaped plate 602, which is convenient for combination with the limiting member 7.

[0028] In the embodiment of the utility model, the limiting member 7 includes a limiting plate 701, a limiting groove 702 adapted to the arc plate 602 is longitudinally opened on the plate wall of the limiting plate 701, a locking tooth group 703 is fixed on the upper side of the limiting groove 702, the locking tooth group 703 is in the shape of a triangle, and the tip of the locking tooth group 703 is connected to the upper side of the arc plate 602 by clamping, and two elastic support members 704 are fixed on the lower side groove wall of the limiting groove 702.

[0029] Working principle: This embodiment provides a dust removal structure for a pulverizer. When in use, the feeding port of the pulverizer body 1 can be closed by cooperating with the shielding frame 2 and the dust shielding plate 5, so that the amount of dust leakage during the pulverizing process is reduced. When the pulverizing work is performed, the dust collector 4 can be started and aligned with the pulverizing chamber position with the cooperation of the guide member 3, so that the dust generated by the pulverizing can be sucked into the dust collector 4, and then the dust can be sent to the collection bucket through the discharge pipe connected to the connecting pipe on the dust collector 4, so as to achieve the dust removal effect. Through such structural cooperation, the dust removal effect of the pulverizer body 1 can be increased and the pollution to the external environment can be reduced. When it is necessary to add raw materials to the pulverizing chamber, By pulling the arc-shaped adjusting member 6 to squeeze the support rod 705 downward, the upper surface of the arc-shaped adjusting member 6 can be separated from the locking tooth group 703, thereby releasing the restriction. Then, the movement of the arc-shaped adjusting member 6 can drive the dust shield plate 5 to flip inward, thereby opening the feeding port. When a shape greater than or equal to 0 is formed between the arc-shaped adjusting member 6 and the discharge plate, large-volume crushed materials can be conveniently added. When the arc-shaped adjusting member 6 is flipped to an angle less than or equal to 0 with the discharge plate, small-volume materials can be conveniently added, thereby facilitating the feeding operation. When material transportation is required, the arc-shaped adjusting member 6 can be moved again so that it can be moved back, so that the dust shield plate 5 can re-close the feeding port. Such structural coordination can effectively reduce the amount of dust leakage.
