Jaw type structural stone material crushing machine

Abstract

The invention relates to the field of mine equipment, and particularly relates to a jaw type structural stone material crushing machine. The jaw type structural stone material crushing machine comprises a stander, a driving unit, a mobile jaw group, a discharge opening regulating mechanism and a mobile jaw tensioning buffer mechanism, wherein the driving unit, the mobile jaw group, the discharge opening regulating mechanism and the mobile jaw tensioning buffer mechanism are arranged on the stander; the stander comprises a main stander body, a fixed jaw frame and a toggle plate frame; the fixed jaw frame is arranged on the front end inside the main stander body, and the toggle plate frame is arranged on the rear end inside the main stander body; the mobile jaw group is arranged on the main stander body positioned between the fixed jaw frame and the toggle plate frame; the driving unit is connected with the mobile jaw group in a transmission way; and a crushing cavity is positioned between the mobile jaw group and the fixed jaw frame. According to the jaw type structural stone material crushing machine, the discharge opening regulating mechanism is simple in structure, convenient to install and convenient to regulate, and the mobile jaw tensioning buffer mechanism is novel in structure and has good tensioning and buffer effects.

Description

technical field [0001] The invention relates to the field of mining equipment, in particular to a stone crusher with a jaw structure. Background technique [0002] The stone crusher with jaw structure is referred to as jaw crusher for short. It is a kind of mining machinery used for crushing stone. Simulate the movement of the two jaws of animals, so as to crush the materials; during the jaw swing of the movable jaw group, the discharge port adjustment mechanism is used to support the movable jaw group and adjust the discharge between the movable jaw group and the fixed jaw frame Mouth, the movable jaw tightening buffer mechanism is used to tighten the movable jaw group and has a buffering effect. However, the existing jaw crusher has the following two disadvantages: 1. The structure of the adjustment mechanism of the outlet of the existing jaw crusher is complex, cumbersome to install and inconvenient to adjust. 2. The tensioning and buffering mechanism of the movable jaw...

Problems solved by technology

However, the existing jaw crusher has the disadvantages of the following two aspects: 1. The structure of the adjustment mechanism of the outlet of the existing jaw crusher is complicated, the installation is troublesome and the adjustment is inconvenient

2. The tension buffer mechanism of the movable jaw of the existing jaw crusher adopts springs and spring pull rods, and the movable jaw group is tightened by the restoring force of the spring; however, since the movable jaw group of the jaw crusher swings every time The spring is deformed, and the swing frequency is high, so that the spring deformation is too fast, the temperature is high, the heating spring is aging, and the effect of tensioning and buffering is affected
