From the perspective of overall structure, working principle and working performance, the tunnel mucking loader is mainly composed of three major mechanisms of driving, excavating and conveying, and two major systems of hydraulic pressure and electric power. Through the coordination and cooperation of various parts, the specified actions are realized through hydraulic, electric actuators and mechanical transmission mechanisms, and various operating processes are completed.
The mucking machine integrates the four functions of hydraulic travel, excavation and collection, and transportation and loading. Among them, the hydraulic walking function is to drive the front and rear wheels through the hydraulic motor, and the hydraulic motor has three functions: forward, backward, and automatic braking. The four-wheel drive has the characteristics of strong grounding force and strong driving force. The excavation and collection functions are completed by the manipulator, which has the functions of excavation, arm extension, loading and unloading, etc. The boom can be raised and lowered and turned left and right. Digging and collecting operations are fully hydraulically controlled by six operating handles, each handle controls two actions, a total of twelve actions.
The performance of conveying and loading is done by the conveying system. The conveyor frame of the mucking machine is controlled by a hydraulic cylinder, which supports the front wheels when the conveyor frame is lowered. At the same time, the contact surface between the front feed port of the conveyor frame and the ore is closer, and the stability during operation is stronger. At the same time, it can collect bulk materials and level the site. The conveyor belt width is 650mm, and the conveying speed is about 5m/sec. The conveyor belt is driven by a hydraulic motor, which makes the conveying performance more stable and the service life longer.
