A centering crank slider type double cavity jaw crusher

Abstract

The invention discloses a centering crank sliding-block-type double-chamber jaw crusher, and belongs to the technical field of crushing machinery. A movable jaw body 2 is mounted on a supporting seat3 through a centering crank sliding block mechanism. The centering crank sliding block mechanism comprises a crank assembly 1 mounted in the middle of the lower end of the movable jaw body 2. The other end of the crank assembly 1 is connected with an external power. The crank sliding block mechanism further comprises a sliding block 16 which is hinged to the upper end of the movable jaw body 2 through a sliding block supporting shaft 20 and a sliding block supporting sleeve 21. The sliding block 16 is slidably mounted on a sliding path, consisting of a left wear-resisting side plate 15 and a right wear-resisting side plate 22, of the supporting seat 3. The movable jaw body 2 is a connecting rod in the crank sliding block mechanism. According to the centering crank sliding-block-type double-chamber jaw crusher, based on a double-cavity jaw crushing structure of the centering crank sliding block mechanism, the centering crank sliding-block-type double-chamber jaw crusher is suitable fora large jaw crusher and also suitable for a medium jaw crusher, the drag performance of a motor can be remarkably improved, and the stability and service life of belt transmission are obviously improved.

Description

technical field [0001] The invention relates to the technical field of crushing machinery, in particular to a centering crank slider type double-chamber jaw crusher. Background technique [0002] The crushing of minerals is divided into coarse crushing, medium crushing and fine crushing. Jaw crushers, hammer crushers, impact crushers, and gyratory crushers are often used for coarse and medium crushing of minerals; cone crushers are often used for medium crushing of minerals. and fine crushing; roller crushers, ball mills, autogenous mills, and roller mills are often used for fine crushing of minerals. [0003] In 1858, Blake of the United States invented the simple pendulum jaw crusher for crushing rocks, such as figure 1 Shown is a simple pendulum jaw crusher based on a planar six-bar mechanism. The trajectory of any point on the movable jaw plate is a circular arc, such as P on the movable jaw plate j The locus of the point is an arc, E j The trajectory of the point is...

Problems solved by technology

The driving torque on the eccentric shaft is interval and The interval is in a relatively serious asymmetric state, furthermore, the elastic slip rate of the transmission belt is in an asymmetric state, and the slip rate of the motor is also in an asymmetric state, which will cause the temperature rise of the motor to rise and the life of the motor to decrease

Another shortcoming is that the geometric characteristics of the left and right feed ports are left-right asymmetrical. Based on the crank-rocker mechanism with the crank under the The maximum deviation of the displacement of the corresponding point on the surface exceeds 1mm
