Abstract

The invention discloses a jaw crusher. The jaw crusher comprises a connecting rod, an electric control box, an electric motor, a belt, a pulling rod spring, a back toggle plate, a center shaft, a belt wheel, a suspension shaft, a movable crushing plate, a fixed crushing plate, a sensor, a rack, a front toggle plate, rollers and a base. The back toggle plate and the front toggle plate are movably connected through the connecting rod. The rack is mounted on the base with the rollers. The electric control box is arranged on the base. The electric motor is fixedly mounted on the base. The electric motor and the belt wheel are movably connected through the belt. According to the jaw crusher, the used electric motor is an alternating current servo motor, so that the rotating speed of the electric motor is easy to control, the position precision is quite accurate, and a voltage signal can be converted into torque and the rotating speed to drive a controlled object. Poly-rowed teeth are arranged on the right side face of the movable crushing plate and the left side face of the fixed crushing plate, and therefore, the crushing rate is greatly increased.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment application, in particular to a jaw crusher. Background technique [0002] Jaw crushers are widely used in mining, smelting, building materials, highways, railways, water conservancy and chemical industries, etc., to crush various materials with a compressive strength not exceeding 320 MPa. Jaw crushers have various structural forms, and their working principle is the same, that is, to crush materials by moving the crushing plate to do periodic swinging motion. When the moving crushing plate swings around the suspended axially fixed crushing plate, the material located between the two crushing plates will be crushed, split and bent. At the beginning, the pressure is small, so that the volume of the material shrinks, and the materials are close to each other and squeezed tightly: when the pressure rises beyond the strength that the material can bear, it will be broken. Conversely, wh...
