Abstract

The invention provides a jaw crusher toggle plate. The jaw crusher toggle plate comprises a toggle plate body (2) and wear-resisting bodies (1) at the two sides of the toggle plate body (2), wherein the two sides of the toggle plate body (2) are provided with steps, and the wear-resisting bodies (1) are provided with steps (5) matched with the toggle plate body steps (7). The jaw crusher toggle plate disclosed by the invention has the technical effects that firstly, the two ends of the toggle plate body are provided with the wear-resisting bodies, so that the abrasion between the toggle plate body and a toggle plate cushion is alleviated, the service life of the toggle plate is prolonged for 7-8 times and the utilization rate of materials is greatly improved; secondly, the toggle plate body adopts a casting to guarantee that a jaw crusher cracks when non-crushed materials fall into a machine or a machine is seriously overloaded so as to protect a movable jaw and a rack and achieve a safety effect, and the toggle plate body is convenient to replace; and thirdly, one ends of the wear-resisting bodies are circular-arc-shaped, and good rolling abrasion can be formed between the toggle plate and the toggle plate cushion to alleviate the impact on the toggle plate, so that the equipment can be reliably operated for a long period and the use and maintenance costs of the equipment are reduced.

Description

technical field [0001] The invention relates to a novel toggle plate of a jaw crusher, which belongs to the technical field of crushing machinery. Background technique [0002] Jaw crushers are widely used in the medium-sized crushing of various ores in mining, smelting, building materials, roads, railways, water conservancy and chemical industries. The maximum compressive strength of the crushed materials is 320MPa. The jaw crusher is mainly used as a primary (coarse crushing and medium crushing) crushing machine. Existing jaw crushers are divided into three types according to the movement characteristics of the movable jaw: simple swing type, complex swing type and mixed swing type. At present, the complex swing type is the most widely used. The jaw crusher is mainly composed of frame parts, fixed jaw plates, movable jaw parts, movable jaw plates, toggle plates, adjustment parts, tensioning devices, etc. The movable jaw with movable jaw is directly suspended on the ecce...
