Problems solved by technology

[0002] In stone production, crushers are usually used for stone crushing. There are many types of crushers. Commonly used are compound pendulum crushers and simple pendulum jaw crushers. Although these crushers can achieve the purpose of crushing, but due to structural design There are also various problems, such as the upper end of the mobile jaw plate of the compound pendulum jaw crusher is in a circular motion, and the lower end is in an elliptical motion under the action of the toggle plate, and the stone is squeezed between the jaw plates at the same time. Rubbing friction is also formed, and the friction formed under huge pressure greatly wears the jaw plate, resulting in rapid wear of the jaw plate; in addition, some stones are powdered under the action of rubbing and friction, which increases the powder content in the finished product. Flour is not the desired product during processing, an

Embodiment Construction

[0015] The direct pressure jaw crusher of the present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0016] As shown in the figure, the direct pressure jaw crusher of the present invention includes a fixed jaw body 1 equipped with a wear-resistant plate installed in the body and a movable jaw body 1 installed in the body that cooperates with the fixed jaw body and is also equipped with a wear-resistant plate. Jaw body 2, the rear lower side of fixed jaw body 1 is hinged with threaded adjustment rod 3, the adjustment rod 3 is covered with compression spring 4, the rear end of adjustment rod 3 protrudes out of the body and makes the compression spring 4 press on the body The opposite surface of the movable jaw body 2 and the fixed jaw body 1 is provided with an inclination angle of the formed V-shaped gap as a crushing cavity for stone crushing, that is to say, the opposite surface of the movable jaw b...

Abstract

The invention discloses a direct pressure type jaw crusher. The direct pressure type jaw crusher comprises a fixed jaw body and a movable jaw body, wherein a crushing cavity is formed in the oppositesurfaces of the movable jaw body and the fixed jaw body; the inclination angle of a formed V-shaped clearance is used for stone crushing; a limiting device is arranged between the movable jaw body anda machine body; the back end of the movable jaw body is mounted on an eccentric shaft driven by a power device through a bearing; and under driving of the power device, the eccentric shaft can rotateto drive the movable jaw body to perform reciprocating motion under limiting of the limiting device relative to the fixed jaw body, and at the same time, stone entering the crushing cavity can be extruded for multiple times through change of the V-shaped clearance, and crushed stone is discharged outside the crushing cavity. Through adoption of the direct pressure type jaw crusher, advantages ofcompound pendulum and simple pendulum jaw crushers are maintained, the size is smaller, yield is larger, abrasion is lower, the crusher is more energy-saving, crushing capacity is higher, quality is better, the crusher has the advantages that specification selectivity of a crushed product is higher and the product ratio is higher, and the application range is expanded.
