Description
Technical field
The present invention relates to being related to a kind of dual-seal discharging door mechanism of pavement maintenance truck, belong to road maintainance machinery equipment
Technical field.
Background technology
When carrying out asphalt pavement pit repairing, pavement maintenance truck needs the hot-mix asphalt mixture producing mixing plant
（HMA）Heat insulation transportation to construction section, because the temperature of dispatching from the factory of hot-mix asphalt mixture is at 140 ~ 160 DEG C, less than 120 DEG C after drip
Blue or green adhesive property is deteriorated it is impossible to be used for constructing, therefore the solution typically taken is one insulation material of outfit on pavement maintenance truck
Storehouse, arranges conveying worm in insulation feed bin, when pavement maintenance truck reaches construction section, starts conveying worm operating, will
Hot-mix asphalt mixture in storehouse is discharged in pit.Existing pavement maintenance truck, normally only in insulation feed bin internal coiling conveying
The spiral groove end of machine opens up discharging opening, installs a circular arc plate matching with helicla flute, during driving on discharging opening
By on circular arc inserting board, and it is fixed, when needing discharging, circular arc plate is taken off, the hot asphalt in insulation feed bin
Compound is delivered to discharge outlet by conveying worm, and falls in pit.Due to circular arc plate can not accomplish close well
Envelope, heat outwardly scatters and disappears in transportation, and after often occurring reaching construction section, hot-mix asphalt mixture has been cooled to 120
Below DEG C, or even situation, impact pit repairing quality and the construction speed leading to not discharging in discharge outlet cooling caking.This
Outward, because circular arc plate needs manually to extract and plug, waste time and energy, after particularly having adhered to Colophonium, be more difficult to beat
Open.
Content of the invention
The purpose of the present invention is for above-mentioned the deficiencies in the prior art, provides one kind to seal tight, easy to operate, structure conjunction
The dual-seal discharging door mechanism of the pavement maintenance truck of reason.
For solving above-mentioned technical problem, the present invention provides a kind of dual-seal discharging door mechanism of pavement maintenance truck, and it wraps
Include discharge end support base, spiral bin gate, support base bin gate, upper cover plate, executive component, connecting bracket, described discharge end support base
Upper and lower be open type square box structure, described discharge end support base is arranged on the insulation feed bin of pavement maintenance truck
On bulkhead, the one side that described discharge end support base is connected with insulation material silo wall has discharging opening, the spiral in insulation feed bin

The heat mixing asphalt is subject to the dual baffle of spiral bin gate 2 and support base bin gate 3, is difficult to occur heat to hand over extraneous
Change, thus greatly reduce scattering and disappearing of heat.
When pavement maintenance truck travels to construction section, needs to carry out discharging, only executive component 5 need to be operated to stretch out, then prop up
Support seat bin gate 3 slides backward along the sideslip groove 12 of discharge end support base 1, and support base bin gate 3 no longer blocks discharge end support base 1
The unlimited position of bottom, meanwhile, spiral bin gate 2 slides backward along conveying worm central siphon under the drive of support base bin gate 3,
Spiral bin gate 2 also no longer blocks the discharging opening 11 of discharge end support base 1, starts conveying worm, then can be by insulation feed bin
Hot-mix asphalt mixture is delivered to the discharging opening 11 of discharge end support base 1, and the unlimited position via discharge end support base 1 bottom
Freely fall on road surface, you can carry out pit repairing operation.
When needing conveying worm to be overhauled or safeguards, only need to disassemble upper cover plate 4, remove executive component 5, by spiral shell
Rotation bin gate 2 and support base bin gate 3 release annexation, and take out after upper bin gate 21 and discharge door 22 separation, you can by discharging
End support base 1 reverts to unlimited body structure, and personnel can easily touch the spiral being socketed within discharge end support base 1
Conveyer, is overhauled to it or is safeguarded.
The present invention, by means of the dual sealing functions of spiral bin gate 2 and support base bin gate 3, has effectively intercepted in insulation feed bin
The heat of hot-mix asphalt mixture passes through discharging opening 11 scattering and disappearing outwardly, and sealing is tight, high insulating effect, operation side simultaneously
Just it is easy to overhaul.
