Stone crusher

Abstract

The invention relates to a stone crusher, and particularly relates to a stone crusher for crushing stone pieces into granular gravels. The stone crusher comprises a shell, wherein a fixed plate is arranged on the inner side of one wall of the shell; a supporting plate is arranged inside the shell opposite to the fixed plate; a movable plate is arranged on one surface of the supporting plate, close to the fixed plate; the upper edge of the supporting plate is articulated with the upper edge of the shell; a fly wheel is arranged on one side of the shell; a fly wheel shaft is an eccentric shaft of which the two ends are movably arranged on the upper edge of the shell; a fixing frame is arranged outside the movable plate; a fixed wedged block is fixedly arranged on the inner side of the fixing frame; a movable wedged block is arranged on the wedged surface of the fixed wedged block and capable of sliding up and down along the fixed wedged block; connecting rods are arranged at the two ends of the eccentric shaft; the upper ends of the two connecting rods are respectively articulated with the two ends of the eccentric shaft; first and second push rods, pull rods and springs for pushing the movable plate to do a reciprocating motion are arranged among the lower ends of the two connecting rods, the movable plate and a movable slider. The stone crusher is characterized in that a wear resisting layer is arranged on one surface where the movable plate is close to the fixed plate. The stone crusher is long in service life, low in production cost and especially applicable to stone ores.

Description

technical field [0001] The invention relates to a crushing machine. Specifically, it is a stone crusher machine used to break stones into granular gravel. Especially suitable for quarry. Background technique [0002] At present, it is known in the quarry mining industry that the moving plates on the crusher are all processed from a single steel. Since the moving plate is processed from a single steel material, it has low hardness and is easy to wear. If it is not used for a long time, it needs to be scrapped and replaced. Not only the service life is short, but also the production cost is relatively high. Contents of the invention [0003] The problem to be solved by the present invention is to provide a rock crusher. The moving plate of this crusher has a long service life. The stone crusher using this moving plate can greatly reduce the production cost. [0004] In order to solve the above problems, the following technical solutions are adopted: [0005] The stone ...
