Abstract
Claims
1. A cooling fan for the prime mover that drives agricultural machinery, The system includes a control device that controls the cooling fan, The control device is An operation detection unit that detects an operation to change the output of the prime mover, Includes a fan control unit that controls the rotation speed of the cooling fan based on the operation detected by the operation detection unit, Prime engine cooling system.
2. The fan control unit is If the detected operation is an operation that increases the output of the prime mover, control is performed to increase the rotation speed of the cooling fan. If the detected operation is an operation that reduces the output of the prime mover, control is performed to reduce the rotation speed of the cooling fan. The prime mover cooling system according to claim 1.
3. The control device is The system further includes a temperature detection unit for detecting the temperature of the prime mover, The fan control unit is The cooling fan is controlled based on the detected operation and temperature. The engine cooling system according to claim 2.
4. The operation to change the output of the prime mover is, At least one of the following: operation of the PTO (Power Take Off), operation of the driving pedal, and operation of hydraulic equipment. The prime mover cooling system according to claim 1.
5. Agricultural machinery driven by a prime mover, The prime mover is cooled by the cooling fan of the prime mover cooling system according to any one of claims 1 to 4. Agricultural machinery.
6. A method for controlling a cooling fan that cools a prime mover that drives agricultural machinery, The control method described above is A step of detecting an operation that changes the output of the prime mover, The process includes the step of changing the rotation speed of the cooling fan based on the detected operation, Control method.
