Hydraulic driving mechanism of crusher

Abstract

The invention relates to the field of crusher hydraulic technology, in particular to a hydraulic driving mechanism of a crusher. The hydraulic driving mechanism of the crusher comprises a hydraulic motor fixed to a clutch, a braking valve used for braking the crusher, and an overflow valve; the braking valve is connected with the other hydraulic system; the hydraulic motor is connected with an oil tank oil sucking port through a hydraulic pipeline which is provided with a first check valve; and the hydraulic motor is connected with the braking valve. The hydraulic motor is further connected with an electromagnetic valve; the two ends of the hydraulic motor are further connected with electric pump power units; and a hydraulic lock is arranged between the hydraulic motor and each electric pump power unit. The hydraulic driving mechanism of the crusher achieves flexible starting of the crusher, avoids huge impacting and loads caused by starting, and reduces the losses of a belt pulley and a belt; and meanwhile, the utilizing rate of elements of the hydraulic system is fully increased, the efficiency of a whole machine is improved, and the oil consumption of the machine is reduced. Convenience is provided when abrasion pieces in the crusher are replaced and maintained, and the safety performance is also greatly improved.

Description

technical field [0001] The invention relates to the technical field of crusher hydraulics, in particular to a hydraulic drive mechanism of a crusher. Background technique [0002] Mobile crushers are widely used in metallurgy, chemical industry, building materials, hydropower and other materials processing that often require relocation operations, especially for the operation of mobile stone materials such as highways, railways, hydropower projects, etc. Different configuration forms are used depending on the material requirements of the finished product. [0003] like figure 1 As shown in the figure, the current crusher is usually started directly by the coupler, the engine 10' drives the coupler 20', the coupler 20' is connected to the pulley 30', and the pulley 30' is directly connected to the crusher pulley 60' through the belt 40', The pulley 60' drives the crusher rotor 50' to rotate, and the coupler engages in a short period of time during startup, and the crusher s...
