Jaw crusher toothed plate with buffering mechanism

Abstract

The invention discloses a jaw crusher toothed plate with a buffering mechanism. The jaw crusher toothed plate comprises a main connection plate, wherein raised stripes are arranged on the main connection plate; grooves are formed in the back surface of a collision plate; the raised stripes are inserted in the grooves in a sleeving manner; the collision plate presses the main connection plate; a tooth-shaped raised surface is formed on the front surface of the collision plate; a plurality of tooth-shaped raised stripes are uniformly distributed on the tooth-shaped raised surface; secondary tooth-shaped raised stripes are fixedly arranged at two sides of the tooth-shaped raised stripes; an elastic block is fixedly arranged on the top surfaces of the raised stripes; an elongated groove is formed in the middle of the elastic block; a plurality of springs are inserted in the elongated groove in a sleeving manner; the elastic block and the springs are clamped between the top surfaces of the raised stripes and the top surfaces of the grooves. By using the jaw crusher toothed plate, the crushing capacity is improved; simultaneously, the secondary tooth-shaped raised stripes are fixedly arranged at the two sides of the tooth-shaped raised stripes, so that the crushing effect is greatly improved; the elastic block and the springs play a buffering role, so that the damage to the collision plate during crushing can be reduced.

Description

Technical field: [0001] The technology of the present invention relates to the technical field of crusher equipment, and more specifically relates to a tooth plate of a jaw crusher with a buffer mechanism. Background technique: [0002] The tooth plate of the jaw crusher, that is, the jaw plate is an important part of the jaw crusher. The existing jaw plate generally has a toothed surface on one side of the body, and the two side walls of the teeth on the toothed surface are sandwiched The angle is generally 90° to 120°. The included angle of this structure ensures the strength of the teeth, but it weakens the damage ability of the teeth, which greatly affects the crushing effect. Moreover, once the existing jaw plate is damaged, it needs to be disassembled and replaced. It is fixed by bolts, which is troublesome to disassemble and increases the time for replacement. Invention content: [0003] The technical purpose of the present invention is to overcome the deficiencies...
