[0023] By setting the first host drive module and the second host drive module, the first main motor and the second main motor are independently controlled to start and stop, wherein the first host drive module realizes the smooth start of the first main motor by setting a soft starter, thereby reducing the impact on the power grid. The first host drive module and the second host drive module are both provided with circuit breakers, which can cut off the power supply in time when the circuit is overloaded or short-circuited, thereby protecting the main motor and other control components from damage. The first host drive module and the second host drive module are relatively independent, which is convenient for maintenance and repair.

[0024] Preferably, the first host drive module also includes intermediate relays KA2 and KA3, the coil end of the intermediate relay KA2 is connected to the output end of the controller 3, the normally open contacts of the intermediate relay KA2 are respectively connected to the X3 end, COM end, RUN end and SOP end of the soft starter, the normally open contacts of the intermediate relay KA3 are respectively connected to the K1 control end and the AC power supply of the soft starter, and the coil ends of the intermediate relay KA3 are respectively connected to the coil ends of the bypass contactor KM1 and the AC power supply; the second host drive module also includes an intermediate relay KA4, the normally open contacts of the intermediate relay KA4 are respectively connected to the coil ends of the AC contactor KM2 and the AC power supply, and the coil ends of the intermediate relay KA4 are connected to the output end of the controller 3.

[0025] By setting the intermediate relays KA2 and KA3, the output of the controller 3 can control the soft starter, the bypass contactor KM1 and the AC contactor KM2. In the present embodiment, the soft starter adopts the NJR2-D series soft starter, and the controller 3 adopts the SIMATIC S7-200 series PLC controller. The setting of the intermediate relays KA2, KA3 and KA4 can also play the role of isolation and protection. When it is necessary to cut off the first host drive module and the second host drive module, it can be achieved by controlling the state of the intermediate relay without directly operating the main circuit of high voltage or high current, thereby improving the safety of operation. Through the connection between the intermediate relay and the output end of the controller 3, the controller 3 can automatically control the state of the intermediate relay according to the preset program or condition, and then control the start, stop, acceleration, deceleration and other actions of the impact breaker 1, thereby improving the automation level of the production process.

By setting the second current transformer on the L3 phase of the output end of the circuit breaker QM02, it also plays the role of monitoring the current of the second host driver module, and in conjunction with the thermal relay FR, it can provide additional protection when the current is overloaded to prevent the equipment from being damaged due to long-term overload. Therefore, by providing the first current transformer and the second current transformer, the function of current monitoring and protection is achieved.

[0027] Preferably, refer to the attached Figure 5 , and also includes a lubricating oil station 2, the lubricating oil station 2 includes an oil delivery drive module, the oil delivery drive module includes a circuit breaker QM7, a protection switch QM3, an AC contactor KM3 and an oil pump M03, the input end of the circuit breaker QM7 is connected to the three-phase power supply, the input end of the protection switch QM3 is connected to the output end of the circuit breaker QM7, the main contacts of the AC contactor KM3 are respectively connected to the output end of the protection switch QM3 and the oil pump M03, and the coil end of the AC contactor KM3 is connected to the output end of the controller 3.

[0028] Providing a continuous supply of lubricating oil to the impact crusher 1 through the oil pump M03 can not only reduce the friction between the equipment components and reduce wear, but also play a cooling role to prevent the equipment from overheating, thereby increasing the service life of the impact crusher 1 equipment. The circuit breaker QM7 is used as the electrical protection of the oil delivery drive module, the cooling drive module and the heating drive module to ensure that the power supply can be quickly cut off when the current is too large or a short circuit occurs, thereby protecting the safety of the lubricating oil station 2 equipment. The protective switch QM3 can cut off the oil delivery drive module under certain conditions, thereby protecting the oil pump M03 from damage. By setting the main contacts of the AC contactor KM3 to control the power on and off of the oil pump M03, the controller 3 can accurately control the start and stop of the oil pump as needed, and realize the automatic control of the lubricating oil supply.

[0029] Preferably, the lubricating oil station 2 also includes a cooling drive module, which includes a protection switch QM4, an AC contactor KM4 and a cooling fan M04.

The heat dissipation capacity of the lubricating oil station 2 is improved by setting the cooling fan M04, and the lubricating oil is cooled by air cooling, thereby maintaining the stable operation of the system. Similarly, the protection switch QM4 plays an electrical protection role for the cooling drive module. When the cooling fan M04 or its circuit is abnormal, such as excessive current, short circuit, etc., the protection switch QM4 can quickly cut off the power supply. The power on and off of the cooling fan M04 is controlled by the main contacts of the AC contactor KM4, so that the controller 3 can intelligently control the start, stop and speed of the cooling fan according to the real-time temperature, operating status and other factors of the system to achieve the best heat dissipation effect.

[0030] Preferably, the lubricating oil station 2 also includes a heating drive module, which includes a protection switch QM5, an AC contactor KM5 and a heater R06.

In order to avoid the viscosity of the lubricating oil caused by low temperature may increase, the fluidity is reduced, and the lubrication effect of the equipment is affected, this embodiment preheats the lubricating oil by setting a heater R06 to ensure that it reaches a suitable working temperature, thereby maintaining good fluidity and lubrication performance. Among them, the protection switch QM5 plays an electrical protection role for the heating drive module. When the heater R06 or its circuit is abnormal, the protection switch QM5 can quickly cut off the power supply to avoid equipment damage and safety accidents. The power supply of heater R06 is controlled by the main contact of AC contactor KM5, so that controller 3 can intelligently control the start and stop of the heater according to real-time monitoring data such as ambient temperature and lubricating oil temperature, ensuring that the lubricating oil temperature is always maintained within the optimal working range.
