Description

Technical Field

[0001] The utility model relates to the technical field of crusher components, and particularly relates to a crushing component of a hammer crusher. Background Art

[0002] A crusher, also known as a stone crusher, is a crushing machine that can crush the mined raw ore into small particles through extrusion, bending and other means during the processing of metal and non-metal ores. A crusher refers to a crushing machine in which the content of particles larger than 3 mm in the discharge accounts for more than 50% of the total discharge. Crushing operations are often divided into coarse crushing, medium crushing and fine crushing according to the size of the feed and discharge. Common crushing machines include jaw crushers, gyratory crushers, cone crushers, roll crushers, hammer crushers, impact crushers, etc.

[0003] In the utility model patent named a crushing component of a hammer crusher (application number 202220483236.5), it is proposed that "the utility model discloses a crushing component of a hammer crusher, including a circular plate. Both the left and right sides of the circular plate are fixedly connected with main shafts, and a sleeve is sleeved outside the circular plate. A connecting mechanism is arranged between the circular plate and the sleeve. A plurality of vertical blocks are movably connected to both the top and bottom of the sleeve. A vertical groove is opened at the top of the vertical block, and a movable block is installed in the inner cavity of the vertical groove. The top of the movable block extends to the top of the vertical groove and is fixedly connected with a hammer head. A positioning mechanism is arranged between the vertical block and the sleeve. Through the coordinated use of a series of components such as a threaded block, a threaded groove and a cross bar, when an individual hammer head in the utility model is damaged, it can be conveniently disassembled and replaced; through the coordinated use of a series of components such as a movable block, a vertical groove and a locknut, the utility model can adjust the position of the hammer head according to the size of the ore, thereby ensuring its crushing performance." However, this utility model patent has the following problems:

[0004] 1. In this application, when adjusting the position of the hammer head according to the size of the ore, it is not considered that the operator needs to hold the movable block in a determined position and simultaneously tighten the locknut to fix the movable block. Such a treatment method is not good. The operator needs to hold the movable block to make it stationary relative to the vertical groove, and at the same time, a screwdriver is needed to tighten the locknut. Such a method is more cumbersome and inconvenient to operate;

[0005] 2. In this application, it is not considered that it is inconvenient to match the positioning groove provided on the movable block with the positioning hole provided on the vertical groove. It is necessary to manually calibrate accurately many times before installing the locknut. Such a method is too cumbersome to operate and cannot achieve the best treatment effect.
