For achieving the above object, the utility model is by the following technical solutions:
A kind of loose feeder has vibration excitor, and casing, support spring, damper spring, support, casing have the skeleton of square frame shape, and skeleton is welded by shaped steel; Vibration excitor is installed in the side of casing by support spring, and casing is installed on the support by damper spring, and the top of casing is provided with inlet point, and the bottom of casing is provided with discharging opening; It is characterized in that: the edge of described inlet point is equipped with left and right blanking plate, and left and right blanking plate is horn-like left and right symmetric arrangement; Box house central authorities are horizontally arranged with deflecting plate, the shape of deflecting plate is middle high, the low arch in two ends, there is the left and right flanging of downward extension at the edge, two ends of deflecting plate, below left and right flanging, be provided with left and right coal passing plate, left and right coal passing plate is downward-sloping ramp, the upper edge of left and right coal passing plate is welded on respectively on the box frame, leaves opening between the lower edge of left and right coal passing plate, and this opening part is welded with bevelled discharge bucket.
The lower edge of described left and right coal passing plate is hinged with left and right regulating plate respectively.
The top of described inlet point is provided with flange suitable for reading, and flange suitable for reading is connected with casing upper end flexible sealing by soft cloth.
The below of described discharging opening is provided with the end opening flange, and the end opening flange is connected with casing lower end flexible sealing by soft cloth.
The utility model has following positive beneficial effect:
Loose feeder of the present utility model, coal supply function and bulk material function organically are combined into one, be applicable to the material of various viscosity, the vibration of feeder adds the smooth streamline shape of baffle upper plate, guaranteed the free feeding of coal charge, even the sticking colliery of brown coal or other is feed smoothly also, eliminate the problem that the storehouse is blocked up in swollen storehouse effectively.
Loose feeder of the present utility model, simple in structure, easy for installation, be easy to safeguard, adopt the principle work of subresonance, power is little, and energy consumption is low, adopts fully enclosed casing, the coal inlet of casing, coal outlet carry out soft seal, there is not the material of leakage phenomenon during coal supply, free from environmental pollution, can stepless automatic compensation coal output.
