The invention discloses an integrated central feeder which solves the problem that existing devices are huge in structure and large in
energy consumption. The integrated central feeder is characterized by comprising a straight-
barrel feeding bin, a central discharging
pipe, a hydraulic oil
station and four hydraulic pushing devices, wherein the hydraulic pushing devices are uniformly arranged around a lower wall of the straight-
barrel feeding bin, each hydraulic pushing device comprises a pushing plate, a pushing rod, a sealer and an oil jack, the pushing plates are mounted on the pushing rods which penetrate through a wall of the straight-
barrel feeding bin to be connected with
piston rods of the oil jacks through the sealers, the oil jacks are fixed on the wall of the straight-barrel feeding bin, and each pushing plate comprises an arc-shaped plate, a wedge-shaped scraping plate, a straight-plate scraper and a retaining plate. The integrated central feeder is good in sealability, convenient to repair and maintain, low in
energy consumption, supportive of automatic start during material blockage, reasonable in design, simple in structure, obvious in dredging effect, energy-saving, environment-friendly, high in adaptability, suitable for solving problems of blockage of a raw
coal bin, unsmooth
coal unloading and the like of a thermal power
plant, and also suitable for storage bins for material conveying of other industries.
