Hydraulically-driven long-stroke horizontal continuous feeding device for large vacuum smelting furnace

The invention belongs to the technical field of vacuum metallurgical equipment, and particularly relates to a hydraulically-driven long-stroke horizontal continuous feeding device for a large vacuum smelting furnace. The hydraulically-driven long-stroke horizontal continuous feeding device of the large vacuum smelting furnace can realize long-stroke mass feeding. The hydraulically-driven long-stroke horizontal continuous feeding device comprises a telescopic oil cylinder, an oil cylinder support, a feeding bin, a feeding bin cover, a bin cover oil cylinder, a vacuum isolation valve, a material pushing rail assembly, a guide wheel, a feeding roller, a material pushing trolley, material pushing wheels, a material pushing trolley rear plate, a material pushing plate, a rail, an evacuation connector and a feeding baffle. The telescopic oil cylinder is installed at one end of the feeding bin and connected with the material pushing trolley. The feeding bin cover is arranged on the feeding bin, a vacuum isolating va
