Embodiment
The utility model is illustrated below in conjunction with accompanying drawing.
As shown in figure 1, a kind of biomass boiler feeding system of the present utility model, including feed bin 1-1, feed bin 1-2, vibration
Dispenser 2, material blanking tube 3, horizontal screw conveyer 4, inclined screw conveyor 5 and hopper 6, the feed bin are back taper feed bin,
Feed bin 1-1 and feed bin 1-2 are respectively placed on weighing unit 7, and weighing unit 7 is supported by support, and weighing unit bottom is provided with biography of weighing
Sensor 8.Charging aperture, audible-visual annunciator are respectively arranged with the top of feed bin 1-1 and feed bin 1-2, bottom is provided with discharging opening, side peace
Equipped with vibrator 9, charging aperture and discharging opening are provided with electrically operated valve 10, the weighing sensor 8, electrically operated valve 10 and vibration
Device 9 controls by PLC.Vibra feeder 2 is horizontally placed on below feed bin discharge hole, and it is defeated that vibra feeder includes vibration
Send with 2-1, be arranged at the U-shaped baffle plate 2-2 of conveyer belt both sides, drive the variable-frequency motor 2-3 of shaker belting transmission.Vibrating transportation
