The shape of the circulating oil pipe is set to be spiral so that the oil can be cooled more effectively through the spiral circulating oil pipe.

[0010] Above-mentioned, the side of the coolant storage tank is provided with a water changing mechanism, and the water changing mechanism includes a motor, the side of the motor is fixedly connected to the side of the coolant storage tank, the output shaft of the motor is fixedly connected to a threaded rod, the circumferential surface of the threaded rod is threadedly connected to a threaded sleeve, the side of the threaded sleeve is fixedly connected to a connecting rod, and the end of the connecting rod away from the side of the threaded sleeve is fixedly connected to a water baffle, and a water outlet is provided on the side of the coolant storage tank, the inner wall of the coolant storage tank is fixedly connected to a support plate, and the top of the support plate is fixedly connected to an expansion body, the inner wall of the coolant storage tank is provided with a start button, and the top of the coolant storage tank is provided with a reminder light.

[0015] 1. The utility model cooperates with each other among the components such as the circulating oil pipe, oil pump and valve of the cooling mechanism. When it is necessary to cool the oil inside the hydraulic oil tank of the sawing machine, the staff first adds coolant to the coolant storage tank through the delivery port, then adjusts the flow of oil with the valve according to work requirements, and then starts the oil pump so that the coolant inside the coolant storage tank transfers heat to the oil inside the circulating oil pipe, and continuously cools down the oil through the spiral circulating oil pipe. The cooled oil enters the hydraulic oil tank of the sawing machine through the return oil pipe. This design achieves the effect of continuously cooling the oil inside the hydraulic oil tank of the sawing machine, improves the working effect of the hydraulic system of the sawing machine, and no longer affects the normal operation of the sawing machine due to system overheating.

[0016] 2. The utility model cooperates with each other among the components of the water changing mechanism, such as the motor, the water baffle and the reminder light. When the temperature of the coolant rises, the expansion body inside the coolant storage tank expands due to the change in temperature. The expansion process of the expansion body squeezes the trigger end of the start button, causing the reminder light to sound an alarm to remind the staff. At this time, the staff starts the motor to open the water outlet. At this time, the coolant inside the coolant storage tank flows out through the water outlet. When the staff completes the replacement of the coolant inside the coolant storage tank, the expansion body returns to its original state, and the start button is reset by the elasticity of the reset spring, thereby turning off the reminder light. This design achieves the effect of replacing the coolant inside the coolant storage tank, preventing the coolant from being used for a long time and the temperature increase affecting the normal use of the cooling mechanism.
