Movable jaw crusher

Abstract

The invention discloses a movable jaw crusher, and mainly relates to the technical field of a crusher. A rack is sequentially connected with a feeding mechanism, a crushing mechanism, an adjusting mechanism and a controlling mechanism, and a group of pulleys are arranged at the bottom of the rack; an infrared sensor is arranged on the inner wall of a feeding box, a fixed toothed plate is fixed onone side of the rack, and a movable toothed plate is fixedly connected with a movable jaw; one end of a pull rod is connected with a hook at the lower part of the movable jaw, the other end of the pull rod is connected with a spring in a sleeved mode, the movable jaw is connected with a toggle plate base in a matched mode through a toggle plate, and the toggle plate base is in sliding connection with an adjusting inclined iron; the rack is sequentially connected with a display and a PLC through a telescopic rod, and an automatic alarm device is arranged at the top of the display. The whole structure of the jaw crusher provided by the invention is very simple, carrying is easy and labor-saving, maintenance is convenient and fast, cost is low, the operation state of the jaw crusher can be conveniently monitored by an operator, labor amount of staff is small, and long-time efficient and stable operation can be kept.

Description

technical field [0001] The invention relates to the technical field of crushers, in particular to a movable jaw crusher. Background technique [0002] Jaw Crusher, also known as Tiger’s Mouth, consists of two jaw plates, the movable jaw and the static jaw. For the crushing of various ores and bulk materials in the chemical industry and other industries, the maximum compressive strength of the crushed materials is 320Mpa. [0003] The working part of the jaw crusher is two jaw plates, one is the fixed jaw plate, which is vertically fixed on the front wall of the machine body, and the other is the movable jaw plate, which is inclined in position and forms a crushing cavity with a large upper part and a smaller lower part with the fixed jaw plate. The movable jaw plate makes periodic reciprocating motions against the fixed jaw plate, sometimes separated and sometimes approached; when separated, the material enters the crushing cavity, and the finished product is discharged fro...

Problems solved by technology

[0005] 1. It requires staff to operate in real time, the work efficiency is low, and the workload is still large;

[0006] 2. Operators cannot monitor its operating status in real time, and deviations and failures are prone to occur during work, resulting in poor safety;

[0007] 3. The volume and weight are large, and the handling is laborious;

[0008] 4. The overall structure is very complex, and the load requirements are high, the maintenance is very cumbersome, and the manufacturing and operating costs are high
