Problems solved by technology

However, when the moisture content of the coal is high or the wall of the silo is thick with coal sticking, the more the air cannon is used, the more the coal will collapse and the coal seam will be more solid, which is more difficult to handle.

Embodiment Construction

[0015] Below in conjunction with accompanying drawing and embodiment, the present invention will be further described:

[0016] like figure 1 , figure 2 As shown, a coal bunker dredging device includes a warehouse wall 1, a supporting plate 2, and a sliding plate 3; the upper end of the supporting plate 2 is connected with the warehouse wall 1 through a hinge 5, and the lower end of the supporting plate 2 is connected by a connecting mechanism 4 It is connected with the warehouse wall 1; the support plate 2 is provided with a guide limit groove 201, and the sliding plate 3 is slidingly matched with the guide limit groove 201; The lift cylinder 6 on which the groove 201 slides.

[0017] The support plate 2 and the sliding plate 3 are connected by the guide limit groove 201, and the sliding plate 3 can slide up and down along the guide limit groove 201, and the up and down sliding of the sliding plate 3 is controlled by the lifting cylinder 6, so as to destroy the adhesion be...

Abstract

The invention discloses an unchoking device and particularly relates to a coal bunker unchoking device. By means of the coal bunker unchoking device, the problem that a coal bunker is choked is solved. The coal bunker unchoking device comprises a bunker wall, a supporting plate and a sliding plate. The upper end of the supporting plate is connected with the bunker wall through a hinge. The lower end of the supporting plate is connected with the bunker wall through a connection mechanism. A guiding and limiting groove is formed in the supporting plate. The sliding plate is in sliding fit with the guiding and limiting groove. The sliding plate is connected with a lifting oil cylinder which enables the sliding plate to slide along the guiding and limiting groove. The sliding plate is driven by the lifting oil cylinder to perform vertical motion, and thus an adhesion structure of a coal bed and the bunker wall is damaged; and the coal bed is made to fall off naturally, and thus the problem that the coal bunker is choked is solved.

Description

technical field [0001] The invention relates to a dredging device, in particular to a coal bunker dredging device. Background technique [0002] The coal bunker in front of the furnace is generally made of iron bunker or cement bunker, and there are also coal bunker made of mixed materials. The structure of the coal bunker mainly includes square cone and conical shape. In the process of use, no matter what kind of coal bunker structure, the coal moves from top to bottom in the bunker, the coal near the center of the bunker moves fast, and the coal near the bunker wall moves slowly. Especially when the coal has a large water content and a large amount of ash, the viscosity of the coal is large, and the fine coal powder adheres to the warehouse wall and gradually thickens. Because the structure of the coal bunker is wide at the top and narrow at the bottom, at the exit of the lowermost part of the coal bunker, the mutual scaffolding of the sticking coal on the surrounding wal...
