Abstract
The utility model discloses an impact crusher board hammer device; the impact crusher board hammer device comprises a hammer plate, a board hammer, a wedge block, a clamping block and a clamping seat, wherein the board hammer is mounted on the hammer plate by the wedge block, the clamping block and the clamping seat; convex strips in a single row are arranged in the middle of one surface of the board hammer; central symmetric convex strips in double rows are arranged on the other surface of the board hammer; and recesses consistent with the convex strips on the board hammer in shape are formed in the clamping seat; and according to the utility model, through the coordinations between the plurality of convex strips, which are arranged on the both surfaces of the board hammer, and the recesses on the clamping seat, the board hammer can be firmly fixed on the hammer plate; meanwhile, after the board hammer is worn, the height of the board hammer can be increased by turning over the board hammer so as to compensate the wear of the board hammer; the utilization rate of the board hammer can reach 65-70%; and the use cost of equipment is reduced.
Description
Technical field
The utility model relates to a kind of impact crushing board hammer device that is applicable in the impact breaker, belongs to the plant equipment field, particularly a kind of impact crushing board hammer device.
Background technology
Because the crushing function of impact breaker is from the rotor that is provided with bar, building stones are because the bar high speed impact on the rotor and the bump on counterpunch board and fragmentation, until building stones are crushed to desired particle size.Building stones enter through bar and counterpunch board repeatedly broken from charging aperture, when the ore grain size after the fragmentation during less than the gap between bar and the counterpunch board, discharge with regard to bottom in the slave, are the product building stones after the fragmentation.Bar is as the attrition component in the equipment, and directly determine use cost its service life, and the utilization rate that how to improve bar has just become to reduce the key of cost, can not regulate now the bar utilization rate and be lower than 45%, wastes larger.
The utility model content
Technical assignment of the present utility model is to provide a kind of impact crushing board hammer device for above prior art deficiency.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of impact crushing board hammer device, comprise hammer dish, bar, wedge, clamp and clamping seats, described bar is installed on the hammer dish by wedge, clamp and clamping seats, be provided with single raised line in the middle of the described bar one side, another side is provided with about middle symmetrical double raised line, described clamping seats be provided with bar on the groove that matches of raised line shape.
Described hammer dish is approximate octagon, and wherein mutually is equipped with hammer dish mounting groove on non-conterminous four limits.
Described clamp is locked by wedge, and fixes by the jackscrew on the clamp.
This utility model is by being arranged on groove fit on flat hammer double sided many raised lines and the clamping seats so that bar can firmly be fixed on the hammer dish, after the simultaneously bar wearing and tearing bar turn-over can be promoted the height of bar, the wearing and tearing of compensation bar, can make the utilization rate of bar reach 65-70%, reduce the use cost of equipment.
Description of drawings
Accompanying drawing 1 is the utility model side perspective structural representation.
