[0002] When renovating a road, the first step is to remove the damaged road surface. The most commonly used equipment in this step is the milling machine. The milling machine is mainly used to cut the surface of the workpiece to obtain a smooth surface, accurate size and good surface quality. With the continuous advancement of milling machine technology, the requirements for equipment stability and flexibility are also constantly increasing. The traditional fixed counterweight device can no longer meet these requirements. The detachable counterweight device for the milling machine is designed to meet the milling machine's requirements for stability and flexibility during operation. The main function of this device is to adjust the center of gravity of the milling machine so that it can maintain a stable operating state in different working environments.

[0003] Existing technologies include: modern milling machines are equipped with adjustable weight blocks, which are located at the bottom of the machine or other appropriate locations. Some milling machines are equipped with hydraulic adjustment systems that adjust the counterweight of the machine by controlling the hydraulic pressure. Advanced milling machines are equipped with electronic control systems that can monitor the weight distribution and operating status of the machine through sensors and automatically adjust the counterweight.

[0004] However, the traditional counterweight is fixedly installed on the machine and cannot be removed or replaced, which limits its flexibility. At the same time, the position of the counterweight is fixed, and it is impossible to accurately adjust the counterweight according to specific work requirements. Adjusting the traditional counterweight requires a lot of manpower and time, and once the counterweight is installed, adjusting or replacing the counterweight requires a large amount of operation. Therefore, a detachable counterweight device for a milling machine is proposed to solve the above problems. Utility Model Content

[0026] Working principle: When using the counterweight device, turn the two switches 8 respectively, and the two switches 8 will rotate and drive the two sliders 2 to move downward respectively.
