Movable jaw assembly of jaw crusher

Abstract

The invention provides a movable jaw assembly of a jaw crusher, and belongs to the technical field of crushers. The movable jaw assembly comprises protective plates, a movable jaw and a fixed jaw; theprotective plates are arranged in front of and behind the movable jaw and the fixed jaw; the top of the movable jaw is fixedly connected with a lantern ring; a first motor is arranged on the left side of the movable jaw; an eccentric shaft is arranged in the lantern ring and fixed to the eccentric position of a rotating wheel; the first motor and the rotating wheel are connected through a belt; the movable jaw comprises a movable jaw plate, a movable jaw plate bracket and a plurality of second reinforcing ribs; and the movable jaw plate bracket is welded to the left side of the movable jaw plate, and the multiple second reinforcing ribs are arranged between the movable jaw plate bracket and the movable jaw plate at equal intervals. Rotating rollers are utilized to act on the surface of amaterial, downward acting force is provided for the material, rebound of the material and continuous overturning of the material in a crushing area can be effectively prevented, thus quick material discharging is completed, and the crushing efficiency is improved.

Description

technical field [0001] The invention relates to a crusher device, in particular to a jaw crusher movable jaw assembly. Background technique [0002] Jaw crusher is commonly known as jaw crusher, also known as tiger mouth. The crushing cavity is composed of two jaw plates, the movable jaw and the static jaw, which simulate the movement of the two jaws of animals to complete the material crushing operation. Jaw crushers are mainly used as primary crushers and secondary crushers in mining, building materials, infrastructure and other departments. According to the width of the feed port, it is divided into three types: large, medium and small. The machine with a feed port width greater than 600MM is a large machine, the one with a feed port width of 300-600MM is a medium-sized machine, and the one with a feed port width less than 300MM is a small machine. machine. The jaw crusher is simple in structure, easy to manufacture and reliable in operation. The working part of the j...

Problems solved by technology

[0003] In order to prevent the rebound of materials, the existing jaw crushers mostly make the working surfaces of the movable jaw plate and the fixed jaw plate into a tooth-shaped structure, but the fixed jaw plate of this jaw crusher is mostly placed vertically, and the movable jaw plate The angle between the fixed jaw plate and the fixed jaw plate is about 20 degrees. Therefore, during the operation of the jaw crusher, the shape and particle size of the processed materials often cause the movable jaw to rebound during extrusion, especially when processing relatively square materials. The rebound situation is more obvious, which greatly affects the processing capacity of the jaw crusher
