Hydraulic control system of cone crushing main machine and control method thereof

Abstract

The invention relates to the technical field of cone crushing equipment, in particular to a hydraulic control system of a cone crushing main machine and a control method thereof. The hydraulic controlsystem is characterized by comprising a plurality of adjusting hydraulic cylinders, a plurality of dumpy jack hydraulic cylinders, a discharge opening adjusting circuit, an upper rack retaining circuit, a power component and a hydraulic oil tank. The adjusting hydraulic cylinders are arranged in parallel, the power component is used for converting hydraulic oil in the hydraulic oil tank into pressure oil and supplying the pressure oil to the discharge opening adjusting circuit and the upper rack retaining circuit, the discharge opening adjusting circuit is used for controlling action of the adjusting hydraulic cylinders, the adjusting hydraulic cylinders are used for driving an upper rack to move up and down to adjust the size of a discharge opening, the upper rack retaining circuit is used for controlling action of the dumpy jack hydraulic cylinders, and the dumpy jack hydraulic cylinders are used for jacking up a wedge-shaped ring and keeping the upper rack and a main machine rack expanded. The hydraulic control system is novel in integral structure, stable and reliable to operate, low in failure rate and convenient and rapid to operate and guarantees normal operation of the cone crushing main machine effectively.

Description

technical field [0001] The invention relates to the technical field of cone crushing equipment, in particular to a hydraulic control system of a cone crushing main engine and a control method thereof. Background technique [0002] During the working process of the cone crusher, the motor drives the eccentric cone to rotate through the V-belt, pulley, bevel gear and other transmission devices. Due to the eccentric effect of the eccentric cone, the movable cone of the cone crusher sometimes approaches and sometimes moves away from the fixed cone around the center line, and the materials are continuously impacted, squeezed and bent in the crushing chamber to achieve crushing operations. [0003] The existing cone crushers mainly include floating bowl-shaped tile cone crushers, spiral cone crushers and floating head cone crushers. However, the floating bowl-shaped tile cone crusher main engine cannot be used due to the unreasonable design of its hydraulic system. Ensure the lon...

[0003] The existing cone crushers mainly include floating bowl-shaped tile cone crushers, spiral cone crushers and floating head cone crushers. However, the floating bowl-shaped tile cone crusher main engine cannot be used due to the unreasonable design of its hydraulic system. Ensure the long-term stable and reliable operation of the cone crushing main engine, and it is not convenient for the operation of the cone crushing main engine, including the adjustment of the size of the discharge port, etc., and it is easy to cause the upper frame to loosen on the main frame during the long-term work of the cone crushing equipment , resulting in damage to the device
