Crushing cavity control mechanism for cone crusher

Abstract

The invention relates to a crushing cavity control mechanism for a cone crusher. The crushing cavity control mechanism comprises a feed hopper, an upper lining plate and a main rack, and is structurally characterized by further comprising a supporting sleeve, an adjusting sleeve, an external gear ring, a pushing cylinder, a locking ring, 16 locking cylinders, 8 hydraulic cylinders and 4 jacks, wherein the supporting sleeve is movably connected to the main rack, the locking ring is movably connected to the supporting sleeve, the adjusting sleeve is in threaded connection into the locking ring and the supporting sleeve, the 16 locking cylinders are all arranged on the supporting sleeve, hydraulic cylinder bodies in the 8 hydraulic cylinders are all fixedly arranged on the main rack, the feed hopper is fixedly arranged on the adjusting sleeve, the outer gear ring is fixedly arranged on the feed hopper, the pushing cylinder is arranged on the supporting sleeve, the 4 jacks are all arranged on the main rack, and lifting ends of the 4 jacks are all supported against the supporting sleeve. According to the crushing cavity control mechanism, the size of a crushing cavity can be conveniently and efficiently adjusted; the size of a throat can be controlled; equipment can be effectively protected from being damaged when uncrushable objects enter the crushing cavity.

Description

technical field [0001] The invention relates to a crushing chamber control mechanism, in particular to a crushing chamber control mechanism used in a cone crusher, which belongs to a part of the cone crusher, and can conveniently and effectively adjust the size of the crushing chamber and effectively control the cone crusher. The size of the ore discharge port in the crusher can effectively protect the equipment from damage when objects that cannot be crushed enter the crushing chamber, and can conveniently and effectively remove non-broken objects in the crushing chamber. Background technique [0002] Cone crusher can be widely used in metallurgical industry, construction industry, road construction industry, chemical industry and silicate industry, suitable for crushing hard and medium hard ores and rocks, such as iron ore, copper ore, limestone, quartz , granite, sandstone, etc. During the operation of the cone crusher, it is inevitable that objects that cannot be crushed...
