Abstract

The invention discloses a device for controlling the hydraulic circuit and the lubricant oil circuit of a cone crusher. The device is arranged on the cone crusher, and is connected with an oil cylinder positioned on the cone crusher through an oil pipe. The device is characterized by comprising a shell, wherein the hydraulic circuit and a lubricant circuit are arranged inside the shell; the hydraulic circuit comprises a hydraulic oil tank arranged inside the shell and used for storing hydraulic oil; the hydraulic oil tank is connected to a hydraulic oil pump with double circuits for providing hydraulic power through an oil pipe; inlet and outlet ports at the two ends of the hydraulic oil pump are connected to a control valve through oil pipes, and are connected to an energy storage device through oil pipes; the energy storage device is connected with the oil cylinder through an oil pipe. The device further comprises the lubricant circuit, wherein a lubricant filter is directly connected with a lubricant oil pipe through an oil pipe; the oil cylinder is connected with a lubricant oil tank through an oil return pipe. The device can take away worn waste residues, generated during the operation, in the crusher, so that secondary damage of the waste residues to the crusher is reduced, and the service life is prolonged; meanwhile, the flowing capacity of the oil circuit is increased, a better lubricating effect is achieved, and thus safe and stable operation of the crusher is guaranteed.

Description

[0001] technical field [0002] [0003] The invention relates to the field of mining machinery, and relates to a device for controlling a hydraulic circuit and a lubricating oil circuit of a cone crusher. [0004] Background technique [0005] [0006] Cone crushers are widely used in mining machinery, mainly for crushing some ores and rocks with medium and above medium hardness. When it is necessary to control the particle size of the broken material or when encountering hard-to-break objects such as iron blocks, it is necessary to control the up and down movement of the main shaft in time to adjust the gap between the movable cone liner and the static cone liner; the hydraulic pressure developed in recent years The vertical cone crusher adjusts the up and down movement of the main shaft through the hydraulic system, which greatly improves the work efficiency compared with the previous adjustment by mechanical transmission or manual operation. [0007] However, the hyd...
