Jaw crusher with tooth plate abrasion limiter and tooth plate abrasion limiter

Abstract

The invention discloses a jaw crusher with a tooth plate abrasion limiter. The jaw crusher comprises a fixed tooth plate and a movable tooth plate. The tooth plate abrasion limiter is arranged at the position, 1 / 4-1 / 6 away from the discharging port end, of the fixed tooth plate and / or the movable tooth plate. The tooth plate abrasion limiter comprises a detection portion and a fixing portion. Two abrasion line accommodation holes are formed in the detection portion. A line penetrating groove is formed in the fixing portion. A first abrasion line is arranged in the first abrasion line accommodation hole, a second abrasion line is arranged in the second abrasion line accommodation hole, and the two abrasion lines are led to the back of the fixed tooth plate or the movable tooth plate through the line penetrating groove of the fixing portion respectively to be connected with a signal processor. According to the jaw crusher with the tooth plate abrasion limiter, the tooth plate abrasion limiter is arranged at the maximum abrasion position (that is, 1 / 4-1 / 6 away from the discharging port end) of the fixed tooth plate or the movable tooth plate, and accordingly, the abrasion degree of the fixed tooth plate can be determined and observed in real time. The invention further discloses the tooth plate abrasion limiter of the jaw crusher.

Description

technical field [0001] The invention relates to a jaw crusher, in particular to a jaw crusher with a tooth plate wear limiter. The invention also relates to a tooth plate wear limiter of a jaw crusher. Background technique [0002] Jaw crushers are mainly used for medium-sized crushing of various ores and bulk materials, and are widely used in mining, smelting, building materials, roads, railways, water conservancy and chemical industries. The working part of the jaw crusher is two tooth plates, one is the fixed tooth plate, which is fixed vertically (or the upper end is slightly outward) on the front wall of the machine body, and the other is the movable tooth plate, which forms a large upper and lower small tooth plate with the fixed tooth plate. The crushing cavity (that is, the working cavity). During the crushing process, the motor drives the eccentric wheel on the movable tooth plate to rotate, so that the distance between the movable tooth plate and the fixed tooth ...

Problems solved by technology

This method of relying on human eye observation not only wastes manpower, but also has insufficient accuracy. It is impossible to accurately judge whether the degree of wear of the tooth plate has reached the limited position, and it cannot provide timely and accurate downtime to replace the tooth plate, so it is observed by human eyes. Not only can not completely avoid the damage to the body, but also waste a lot of manpower
