Ore coarse crushing device for mining

Abstract

The invention discloses an ore coarse crushing device for mining. The device comprises a lower baseplate; a left stand column and a right stand column are vertically and fixedly mounted on the lower baseplate; the lower end of a lifting rod is hinged with a V-shaped rod; the right end of the V-shaped rod is in sliding fit connection with a first kidney-shaped hole through a pin; a transverse transmission shaft penetrates through the right stand column in a manner of sliding rightwards; a connecting rod is vertically and fixedly mounted at the right end of the transverse transmission shaft; a slide cavity is formed in the right side wall of a crushing basket; a movable block is embedded in the slide cavity in an up-down sliding manner; a limiting column is vertically and fixedly mounted on the lower baseplate; an elliptic cam is rotationally arranged on the lower baseplate through a bracket; an output shaft of a driving motor is connected with a driving belt wheel; a crushing pressure block is fixedly mounted at the lower end of a longitudinal transmission rod; and the crushing pressure block is positioned above the crushing basket. The device is skillful in structure; and ores in the crushing basket can be uniformly spread and distributed on the bottom surface in the crushing basket, so that the ores can be uniformly crushed by the crushing pressure block, the crushing efficiency is higher, and the coarse crushing process of the ores is more stable.

Description

technical field [0001] The invention relates to the technical field of mining machinery, in particular to an ore coarse crushing device for mining. Background technique [0002] Ore refers to mineral aggregates mined from ore bodies, from which useful components can be extracted. Ore is formed in various geological mineralization processes, and ores formed by different geological mineralization processes have different characteristics. Under modern technical and economic conditions, it is possible to process and extract metals or other products from minerals on an industrial scale. Originally refers to the solid matter mined from metal deposits, but has now been expanded to non-metallic minerals such as sulfur, fluorite and barite accumulated in the parent rock after formation. The ore grade is often used to measure the value of the ore, and the composition of the ore And the amount of harmful impurities also affect the ore value. [0003] In the mining and processing indu...

Problems solved by technology

[0003] In the mining and processing industry, due to the large amount of unusable impurities in the mined ore, it is necessary to carry out preliminary coarse crushing treatment before further processing, so that the larger ore can be cracked and broken. , the existing ore primary crushing device has poor crushing effect on ore, and the crushing range is small, which makes the ore primary crushing efficiency low and directly affects the speed of mineral processing. Therefore, it is urgent to provide a mining ore primary crushing device In order to improve the effect of coarse crushing of ore and speed up the speed of coarse crushing of ore
