Description
Technical field
The utility model belongs to construction refuse regenerated and utilizes equipment, more particularly to a kind of metering device of pitch.
Background technology
With the fast development of highway particularly high-type highway building cause, the research in terms of highway in China construction obtains
Many achievements, this also proposes higher requirement to asphalt pavement construction equipment.Asphalt mixing plant is as construction
In visual plant, possess number of units and newly-increased number of units is increasing year by year, and pitch metering device is in asphalt mixing plant
In have vital effect.
Pitch metering device currently on the market uses butterfly valve as drain hole headstock gear more, or will using pumping mode
The problems such as pitch is sent into agitated kettle, but complicated, more, the short life of leakage in various degree be present, and maintenance cost is high.
The content of the invention
The shortcomings that in order to overcome prior art, the utility model provide a kind of pitch metering device.It is simple in construction, cost
It is low, service life length.
The technical scheme in the invention for solving the technical problem is：Bituminous pitch storing bucket, pitch are fixed in support
The bitumen feed pipe and steam vent communicated with bituminous pitch storing bucket inner chamber, the roof of bituminous pitch storing bucket are fixed with the roof of storage bucket
Cylinder is fixed with centrally through air cylinder support, the piston of cylinder is fixed by the upper end of universal joint and guide rod, under guide rod
The valve element with blowing cone valve is held to fix, the valve base sealing coordinated with valve element is fixed on the bottom wall hole of the bituminous pitch storing bucket, valve
Seal and fix with the upper end of discharging tube in the outlet of seat, it is intraoral that entering for pitch oblique flow pipe is stretched into the lower end of discharging tube, pitch oblique flow
The outlet of pipe communicates with a mixing bowl.
The utility model is simple in construction, and cost is low, service life length.
Brief description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples.
Fig. 1 is the utility model structure diagram.
