Description

Technical Field

[0001] This utility model relates to the field of control circuit technology, and in particular to a rice machine control circuit. Background Technology

[0002] As a key piece of equipment in grain processing, the stable operation of rice processing machines directly affects the efficiency and quality of rice processing. Existing rice processing machine control circuits often suffer from the following problems:

[0003] Traditional circuits often use a single switch to control the synchronous start and stop of multiple motors, making it impossible to operate each piece of equipment (such as rice milling machines, rice hullers, and elevators) independently. This necessitates the overall start and stop of the entire system during processing, increasing energy consumption and potentially disrupting the entire production line due to a single equipment failure. Furthermore, the lack of real-time monitoring of the operating current of each motor and the total power supply makes it difficult to intuitively determine whether the equipment is in an abnormal state such as overload or jamming. Problems are often only discovered after the equipment has stopped or failed, increasing maintenance costs and downtime.

[0004] Some control circuits rely solely on simple fuses for overcurrent protection, resulting in slow response and low protection accuracy. They are unable to provide precise protection against different fault types, such as motor overload and short circuits, easily leading to serious consequences like motor burnout. The lack of clear equipment operating status indicators makes it difficult for operators to quickly determine whether each piece of equipment is functioning properly. This can easily lead to operational errors when multiple devices are operating in tandem, impacting processing efficiency and safety.

[0005] Therefore, a rice-making machine control circuit needs to be designed to solve the above problems.

The rice milling machine motor M1, the rice hulling machine motor M2, the elevator destoner motor M3, the fan motor M4, and the gravity screen motor M5 are each connected to their respective contactors KM1.

[0029] When the main circuit breaker QF1 is closed, the contactor KM1 is energized and engaged, providing a power supply path for the rice milling machine motor M1, the rice hulling machine motor M2, the elevator destoner motor M3, the fan motor M4, and the gravity screen motor M5. Each motor can start and run according to the control command.

[0030] Specifically, the equipment monitoring circuit includes a total power current monitoring ammeter A1, a rice milling machine ammeter A2, a rice huller ammeter A3, and a hoist destoner fan ammeter A4. The total power current monitoring ammeter A1 is connected to the power input terminal, the rice milling machine ammeter A2 is connected to the rice milling machine motor M1, the rice huller ammeter A3 is connected to the rice huller motor M2, and the hoist destoner fan ammeter A4 is connected to the hoist destoner motor M3 and the fan motor M4.

[0031] With the above structure, when the motor is overloaded, the thermal relay will cut off the power supply to the contactor coil, causing the motor to stop running and achieving overload protection.

[0037] Working principle:

[0038] In the main power supply control circuit, power is introduced through the main circuit breaker QF1. The main circuit breaker QF1 acts as the main power switch and can automatically disconnect when the circuit has faults such as overcurrent or short circuit, ensuring the safety of the overall circuit. When the main circuit breaker QF1 is closed, the contactor KM1 is energized and engaged, providing a power supply path for the rice milling machine motor M1, the rice hulling machine motor M2, the elevator destoner motor M3, the fan motor M4, and the gravity screen motor M5. Each motor can start running according to the control command.

The rice milling machine ammeter A2, the rice huller ammeter A3, and the elevator destoner fan ammeter A4 monitor the operating current of their respective motors. Operators can intuitively understand the operating load status of each piece of equipment through these ammeters, promptly detect abnormal current conditions, and facilitate troubleshooting potential faults such as motor overload.

[0040] In the auxiliary control indication circuit, circuit breaker QF2 provides overcurrent protection for the control circuit. When button SB1 is pressed, the coil of contactor KM2 is energized and its main contacts close, starting the rice milling machine motor M1. At the same time, the rice milling machine indicator light H1 illuminates, indicating that the rice milling machine is in working condition. Similarly, pressing buttons SB2, SB3, and SB4 can control the rice huller motor M2, the elevator destoner motor M3, and the gravity screen motor M5 to start via contactors KM3, KM4, and KM5, respectively. The corresponding indicator lights H2, H3, and H4 illuminate synchronously. The thermal relay FR1 is connected in series with the motor. When the motor is overloaded, the thermal relay operates to cut off the power supply to the contactor coil, stopping the motor and achieving overload protection. The coordinated operation of each part of the circuit realizes the orderly control, operation status monitoring, and fault protection of each piece of equipment in the rice milling machine, ensuring the stable and reliable operation of the rice milling machine.
