Abstract

The invention relates to a hydraulic system for a cone crusher. The hydraulic system for the cone crusher comprises an oil supplying system, a locking loop, an adjusting motor loop and an iron-encountering releasing and cleaning loop. The oil supplying system is composed of an oil tank, a motor and an oil pump. The locking loop is composed of a plunger cylinder and a fourth three-position-four-way valve. The adjusting motor loop is composed of a first oil motor, a second oil motor, a first three-position-four-way valve and a second three-position-four-way valve. The iron-encountering releasing and cleaning loop is composed of a third three-position-four-way valve, a locking oil cylinder and a releasing oil cylinder. Compared with the prior art, the hydraulic system for the cone crusher has the advantages that due to the fact that the condition that braking systems of the oil motors are braked by a brake is changed into the condition that the braking systems of the oil motors are controlled by hydraulic valves, the hydraulic system operation is more reliable; the hydraulic system control points are substantially reduced, and the fault occurrence rate is effectively decreased; by fully adopting domestic hydraulic elements, the price is low, and the maintenance is convenient; the electromagnet working conditions of solenoid valves are visually displayed through indicator lamps once a fault occurs, a fault point can be rapidly and accurately found, and the maintenance efficiency is improved.

Description

technical field [0001] The invention relates to a hydraulic system, in particular to a hydraulic system of a cone crusher. Background technique [0002] With the continuous development of my country's iron ore beneficiation technology, "more crushing and less grinding" is increasingly becoming the goal pursued by many ore dressing plants. In recent years, HP series cone crushers have developed rapidly in domestic applications, and have been well applied in many mineral processing plants. efficiency. However, due to the unreasonable design of its hydraulic circuit, the failure rate is high during long-term use; in addition, failures caused by the failure of the oil motor brake device also occur from time to time. Since HP series cone crushers are imported equipment, spare parts need to be imported, resulting in relatively high operating costs and long spare parts storage cycle, so we have redesigned its hydraulic system. Contents of the invention [0003] The invention p...
