Adjustment device of cone crusher

Abstract

The invention discloses an adjustment device of a cone crusher. The frame is provided with a support arm, and the top of the main shaft is provided with a shaft shoulder. The top of the main shaft is equipped with a radial force bearing. On the thrust bearing, the thrust bearing is installed on the lower part of the lock arm, the upper part of the lock arm is installed on the piston, the piston is arranged in the working cylinder, and the working cylinder is fixed on the support arm of the frame , the working cylinder includes a pneumatic cylinder, a hydraulic cylinder, and a diaphragm, the diaphragm separates the pneumatic cylinder from the hydraulic cylinder, and the hydraulic cylinder is arranged on the pneumatic cylinder. The technical purpose of the present invention is to provide an adjustment device for a cone crusher which is easy to adjust the distance between the movable cone and the fixed cone, and does not need to be provided with an oil tank and an accumulator for oil and gas adjustment.

Description

technical field [0001] The invention relates to an adjusting device for a cone crusher, in particular to an adjusting device for a cone crusher. Background technique [0002] In metallurgy, mining, chemical industry, cement and other industrial sectors, a large amount of raw materials and reused waste need to be processed by crushers every year, so it is necessary to use crushing machinery to crush the raw materials to the particle size required by the next operation, especially in A large number of crushers are required in the mining industry. [0003] Cone crushers are widely used in metal and non-metal mines, cement plants, sand and gravel metallurgy and other industries. It is suitable for medium and fine crushing of various ores and rocks with a Platts hardness ≤ 5-16, such as iron ore, non-ferrous metal ores, granite, limestone, quartzite, sandstone, pebbles, etc. Generally, the cone crusher is a crushing machine for medium or fine crushing operations. The discharge ...

AI Technical Summary

Problems solved by technology

Generally, the cone crusher is a crushing machine for medium or fine crushing operations. The discharge port of the cone crusher is small, and the non-broken materials mixed into the feed are more likely to cause accidents, and because the medium and fine crushing operations have strict requirements on the discharge particle size, Therefore, the insurance and adjustment device of the cone crusher is more necessary than the coarse crushing operation, and the adjustment device of most traditional cone crushers has the disadvantages that the distance between the fixed cone and the moving cone is not easy to adjust or the adjustment is not accurate, and the self-protection ability is poor. And other shortcomings, and the quality of the hydraulic adjustment device of the cone crusher is directly related to the operability of the adjustment of the distance between the fixed cone and the moving cone.

The non-broken objects that have just entered have a very large impact on the traditional high-speed rotating crusher, and can easily cause damage to the cone crusher without shock-absorbing protection. The traditional adjustment device must also be equipped with an oil tank, which increases the impact of the crusher. The floor space is very large, and it is not environmentally friendly.
