The original coal rake machine is heavy and bulky, making it difficult to remove and transport. When the coal raker enters the construction roadway through the belt conveyor, the coal raker must be disassembled through the narrow belt conveyor, and the coal raker is placed directly on the floor of the roadway. When moving on the surface, due to the uneven floor of the roadway, the movement resistance is large, which will cause the rope to be broken, the tail wheel to be pulled out, and even the whole machine to overturn to cause crushing accidents; In the event of water gushing from the bottom plate, the motor will be flooded; when replacing the roller, motor or dealing with the failure of the reducer, it will be difficult to maintain the equipment due to the narrow space; The distance between the belts is large, it is easy to damage the tail buffer roller of the belt conveyor, and it is difficult to take into account the coal sprinkling at the tail of the conveyor during operation. A large amount of coal sprinkling causes the tape conveyor to be blocked from time to time, and accidents such as belt conveyor outage and broken belts occur. It even happened that multiple working chutes superimposed on the upper and lower sides of the rake bucket coal loader injured the operator standing on the side of the superimposed trough, and major safety accidents occurred; The connecting plate between the intermediate trough and the unloading chute is easily damaged and needs to be replaced. Whether it is a mobile rake machine or frequent maintenance during use, it will increase the cost of equipment use.
