[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0021] See also Figure 1 , a dual power supply circuit for a crusher, comprising:

[0022] The live and neutral power supply module is used to obtain AC power by introducing the live and neutral wires, convert it into DC power, and then output it to the battery charging and discharging module and the input isolation module;

[0023] The battery charging and discharging module is used to charge the battery by introducing the DC power output from the live and neutral power supply module when the battery power is low; charging stops when the battery power is sufficient; when the live and neutral power supply module stops outputting DC power, the battery supplies power to the input isolation module;

[0024] Input isolation module, used to isolate the power supply circuit of the firing neutral line power supply module and the battery charging and discharging module to the motor speed control module;

[0025] The motor speed regulating module is used to drive the crusher rotor to rotate when the motor is working;

[0026] The live and neutral wire power supply module is connected to the battery charging and discharging module and the input isolation module. The battery charging and discharging module is connected to the input isolation module. The input isolation module is connected to the motor speed control module.

[0027] In this example: See Figure 2The live and neutral wire power supply module includes a live wire L, a neutral wire N, a transformer W, a rectifier T, a capacitor C1, an inductor L1, a resistor R1, and a resistor R2. One end of the input end of the transformer W is connected to the live wire, and the other end of the input end of the transformer W is connected to the neutral wire N. One end of the output end of the transformer W is connected to the first end of the rectifier T, and the other end of the output end of the transformer W is connected to the third end of the rectifier T. The second end of the rectifier T is grounded. The fourth end of the rectifier T is connected to one end of the capacitor C1 and one end of the inductor L1. The other end of the capacitor C1 is grounded. The other end of the inductor L1 is connected to one end of the resistor R1 and one end of the resistor R2. The other end of the resistor R1 is grounded. The other end of the resistor R2 is connected to the battery charging and discharging module and the input isolation module.

[0028] The voltage introduced by the live wire L and the neutral wire N is converted into a relatively low voltage alternating current through the transformer W, and then converted into a relatively low voltage direct current through the rectifier T. After being filtered by the capacitor C1 and the inductor L1, it becomes a relatively low voltage and stable direct current, which is output to the subsequent circuit.

[0029] In this example: See Figure 2 and Figure 3 The battery charge and discharge module includes a resistor R3, a diode D1, a MOS transistor V1, a MOS transistor V2, a diode D2, a resistor R4, a potentiometer RP1, a battery E1, and a capacitor C2. One end of the resistor R3 is connected to the D pole of the MOS transistor V2, the input isolation module, and the live and neutral wire power supply module. The other end of the resistor R3 is connected to the G pole of the MOS transistor V2 and the positive pole of the diode D1. The negative pole of the diode D1 is connected to the D pole of the MOS transistor V1. The S pole of the MOS transistor V1 is grounded. The G pole of the MOS transistor V1 is connected to the positive pole of the diode D2. The negative pole of the diode D2 is connected to the sliding end of the potentiometer RP1. One end of the potentiometer RP1 is grounded. The other end of the potentiometer RP1 is connected to one end of the resistor R4. The other end of the resistor R4 is connected to the S pole of the MOS transistor V2, the positive pole of the battery E1, one end of the capacitor C2, and the input isolation module. The negative pole of the battery E1 is grounded. The other end of the capacitor C2 is grounded.

[0030] See also Figure 2 When the live and neutral power supply module is supplying power: when the battery E1 is low on power, the voltage at the lower end of the sliding end of the potentiometer RP1 is insufficient, and the voltage regulator diode D2 cannot be turned on. The MOS tube V1 is cut off, the G pole of the MOS tube V2 is at a high level, the MOS tube V2 is turned on, and the battery E1 is charged.

[0031] When the battery E1 is fully charged, the voltage at the lower end of the sliding end of the potentiometer RP1 is sufficient to turn on the voltage regulator diode D2, the MOS tube V1 is turned on, the G terminal of the MOS tube V2 is at a low level, the MOS tube V2 is turned off, and the battery E1 stops charging.

[0032] When the live and neutral wire power supply module is not supplying power: Battery E1 outputs voltage.

[0033] See also Figure 3 MOS tubes V1 and V2 can be replaced by transistors.

[0034] In this example: See Figure 2 The input isolation module includes a diode D3, a diode D4, and a capacitor C3. The positive electrode of the diode D3 is connected to the live and neutral wire power supply module, the positive electrode of the diode D4 is connected to the battery charging and discharging module, the negative electrode of the diode D3 is connected to the negative electrode of the diode D4, one end of the capacitor C3, and the motor speed control module, and the other end of the capacitor C3 is grounded.

[0035] The unidirectional conduction function of diodes D3 and D4 ensures that the power supply circuits of the live and neutral wire power supply module and the motor speed control module will not affect the battery charging and discharging module, and the power supply circuits of the battery charging and discharging module and the motor speed control module will not affect the live and neutral wire power supply module.

[0036] In this example: See Figure 2 The motor speed control module includes a resistor R5, a potentiometer RP2, a MOS tube V3, and a motor M. The D pole of the MOS tube V3 is connected to one end of the potentiometer RP2 and the input isolation module. The G pole of the MOS tube V3 is connected to the sliding end of the potentiometer RP2 and one end of the resistor R5. The other end of the potentiometer RP2 is grounded. The other end of the resistor R5 is grounded. The S pole of the MOS tube V3 is connected to one end of the motor M, and the other end of the motor M is grounded.

[0037] After the voltage is input, the resistor R5 and the right end of the sliding end of the potentiometer RP2 are connected in parallel. The voltage after parallel connection is the G-pole voltage of the MOS tube V3. By adjusting the position of the sliding end of the potentiometer RP2, the G-pole voltage of the MOS tube V3 is changed, the current flowing through the motor M is changed, and the speed of the motor M is changed.

[0038] The working principle of the utility model is as follows: the live and neutral wire power supply module is used to obtain alternating current by introducing the live wire and the neutral wire, and then outputs it into direct current to the battery charging and discharging module and the input isolation module; the battery charging and discharging module is used to introduce the output direct current of the live and neutral wire power supply module for charging when the battery power is insufficient; when the battery power is sufficient, charging is stopped; when the live and neutral wire power supply module stops outputting direct current, the battery supplies power to the input isolation module; the input isolation module is used to isolate the power supply circuit of the live and neutral wire power supply module and the battery charging and discharging module to the motor speed control module; the motor speed control module is used to drive the crusher rotor to rotate when the motor rotates.

Therefore, the embodiments should be considered in all respects as exemplary and non-restrictive.

This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
