[0002] The gantry bucket wheel stacker-reclaimer is a highly efficient bulk material handling equipment. Its tail car guide chute, as one of the key components, plays an important role in the stacking and transportation of materials. The main function of the tail car guide chute is to smoothly and continuously guide the materials from the cantilever belt conveyor or bucket wheel mechanism of the bucket wheel stacker-reclaimer to the tail car or subsequent conveying equipment. It ensures the smoothness and stability of the materials during the conveying process, avoids the spillage and waste of materials, and improves the operating efficiency of the equipment.

[0003] The fixed side plate guide trough used in the tail car of the existing gantry bucket wheel stacker and reclaimer is a welded fixed structure with its side plate and the coal conveyor belt frame. When stacking coal, the burning coal will be scraped out from both sides by the side plates, causing the burning coal to fall onto the return belt and the ground. The burning coal spilled on the ground affects production, increases the labor intensity of cleaning personnel and personal safety hazards, and enters the return belt. The tail car belt deviates, causing serious coal spillage. When the deviation is serious, the belt and frame wear and damage the belt; it can also cause the coal conveyor belt to deviate and fail to operate normally.

[0042] At the same time, the two groups of material guiding components set by the material guiding mechanism 6 are respectively located on both sides of the material conveying belt 9 of the tail car 3, and the material guiding plate 10 is fixedly installed on the top of the fixed frame 1 by the movable support arm 11 and the fixed support arm 12, and then the telescopic end of the electric push rod 17 drives the fixedly connected fixed sleeve 18 to realize up and down movement, and the lower end of the right-angle connecting rod 16 slides through the top of the fixed sleeve 18, and the bottom of the right-angle connecting rod 16 is connected to the bottom of the inner wall of the fixed sleeve 18 through a spring 19.

The lifted distance ensures that the coal flow passes smoothly. When stacking coal, there is no reverse impact of the coal flow on the material guiding trough and the sealing rubber; when taking coal, the material guiding plate 10 is flipped downward to integrate the shape of the coal flow, which is convenient for transportation on the conveyor belt. The electric material guide chute device of the tail car of the gantry bucket wheel stacker and reclaimer changes the original fixed side plate material guide chute of the tail car 3 of the gantry bucket wheel stacker and reclaimer into an electric movable side plate material guide chute, which overcomes the problems of coal spillage of the original material guide chute during coal stacking and the frequent replacement of coal skins by maintenance personnel.
