Abstract

The invention provides a knee plate of a jaw crusher. The jaw crusher comprises a rack, an upper protecting plate, a lower protecting plate, a fixed jaw assembly, a movable jaw assembly, an eccentricwheel, the knee plate, an adjusting seat and a spring pull rod. The lower end of the fixed jaw assembly is connected with the spring pull rod; the spring pull rod is backwards connected to the rack through a spring; a fixed jaw plate is arranged on the fixed jaw assembly, and a movable jaw plate is arranged on the movable jaw assembly; a buffer structure is arranged between the fixed jaw plate andthe fixed jaw assembly, and a buffer structure is arranged between the movable jaw plate and the movable jaw assembly; a plurality of teeth are parallelly arranged on the fixed jaw plate and the movable jaw plate correspondingly; a screening device is further arranged above the movable jaw assembly and the fixed jaw assembly; the lower end of the movable jaw assembly is connected with the front end of the knee plate, and the rear end of the knee plate is connected with the adjusting seat; the adjusting seat is connected to a rack; abrasion resistant bodies are arranged at the two ends of theknee plate; and the knee plate and the abrasion resistant bodies are fixedly connected, and the ends, away from the knee plate, of the abrasion resistant bodies are in circular arc shapes. The knee plate of the jaw crusher is convenient to use, easy to machine, uniform in crushing, high in crushing efficiency, low in cost, resistant to abrasion and long in service life.

Description

technical field [0001] The invention relates to the technical field of crushers, in particular to a toggle plate of a jaw crusher. Background technique [0002] The toggle plate of the jaw crusher consists of two jaw plates, the movable jaw and the static jaw, to form a crushing cavity, which simulates the movement of the two jaws of animals to complete the material crushing operation. It is widely used in the crushing of various ores and bulk materials in mining smelting, building materials, roads, railways, water conservancy and chemical industries. [0003] However, the fixed jaws and movable jaws of the traditional jaw crusher toggle are mostly flat or stepped structures, and the feed is not screened. Most of the crushed materials are various ores and bulk materials. Due to ores and Large pieces of material collide with each other during the conveying process, and there will be gravel, residual materials, etc., which meet the process standards without being crushed in t...
