Description
Technical field
The present invention relates to Road Machinery field, specifically a kind of solid-state adhesion agent dispensing device and its controlling party
Method.
Background technology
Glued in newly-built bituminous paving build basic unit or to the construction site of old pavement cold in place recycling, it is necessary to carry out solid-state
The spreading of agent is tied, for the mechanical property after new pavement basic unit soil stabilization or improvement old pavement regeneration.Conventional solid-state is glued
Knot agent material has the mixture that lime, cement, flyash or above-mentioned different materials are prepared by a certain percentage.Solid-state adhesion
The dispensing device of agent, usually suspended stone spreader used in borrow screening seal coat are converted, and are installed in dress
The dump truck rear portion of full solid-state adhesion agent, to carry out the spreading of material, because suspended stone spreader original design is to be used for
The spreading of rubble, usual ballast grain sizes and porosity are larger, and lime, cement etc. are used as this class of road solid-state adhesion agent
When suspended stone spreader is used for the spreading of solid-state adhesion agent material, there is meter in powder grain material fine particles, porosity very little
Amount is inaccurate, controls inaccurate situation, and because the different brackets such as China's highway, national highway, county road highway width is different,
Suspended stone spreader does not dispense width adjusting function, causes the inconvenience of construction, for example, one standard vehicle of highway
Road width is 3.75m, and the spreading width of suspended stone spreader is 2.5m, when the spreading operation for completing a width 2.5m width
Afterwards, the spreading construction of remaining half range 1.25m width can not be completed individually, can only be taken during operation is dispensed twice,
In center, overlap joint dispenses the wide methods of 1.25m to be constructed, and this construction method, the 1.25m for causing middle lap-joint is wide
Actually carry out dispensing operation twice on road surface, thus spreading amount is big compared with the underlapped position in both sides, causes the waste of material,
While also make it that the cross direction profiles that spreading amount is formd on whole construction road surface are uneven, subsequent base layer stabilization or old pavement have impact on
The construction quality of regeneration.
The content of the invention
The purpose of the present invention be for above-mentioned the deficiencies in the prior art there is provided one kind it is rational in infrastructure, width is adjustable, and raising is applied
The solid-state adhesion agent dispensing device and its control method of working medium amount and efficiency of construction.
The purpose of the present invention is completed by following technical solution, a kind of solid-state adhesion agent dispensing device, including material
Door mechanism, allocation mechanism, spreading mechanism, described discharging door mechanism is laterally arranges in groups, and every group is expected by feed opening, rotation respectively
Door and actuator composition, described feed opening is up-narrow and down-wide tubaeform body structure, its upper and lower ends be it is open go out
Mouthful, it can above be connected with corresponding solid-state adhesion agent conveyer, shaft hole is arranged at the bottom of feed opening, and the sidepiece of feed opening is set
There is key seat；The rotation bin gate is made up of door-plate, rotating shaft, otic placode, and door-plate is rectangular flat, and rotating shaft, rotating shaft are welded with below
End be welded with otic placode, the rotating shaft of the rotation bin gate is engaged with the shaft hole of the feed opening, and can be rotated against；Institute
The tail end for stating actuator is connected with the key seat of the feed opening, the otic placode phase of the head end of the actuator and the rotation bin gate
Connection；
The allocation mechanism is installed on the lower section for the discharging door mechanism arranged in groups, by material toggling case, shift fork and material toggling drive device group
Into；The material toggling case is the square box structure of upper and lower opening, and the shift fork is arranged in material toggling case, driven by material toggling drive device
It is dynamic.
It is described to dispense the lower section that mechanism is installed on the allocation mechanism, by spreading case, spreading roller, dispense drive device structure
Into；Described to dispense the body structure that case is upper and lower opening, the left and right sides is provided with end plate, and front and rear sides are provided with housing, described
Housing is arc plate structure；The spreading roller be located at dispense case in, with it is described spreading case housing it is concentric install, by dispense drive
Device drives；The spreading roller is circular tube structure, and drum surface is uniformly provided with blade paddle shape.
As preferred：The actuator of the discharging door mechanism is three cylinders；The material toggling drive device of the allocation mechanism is
The chain gearing of fluid motor-driven；The spreading drive device of the spreading mechanism is the chain drive of fluid motor-driven
Device.
A kind of control method that solid-state adhesion agent is carried out using the solid-state adhesion agent dispensing device, the control method bag
Include：
Three cylinders three air-path interfaces A, B, C of controller are connected with two-bit triplet magnetic valve respectively, when three cylinders of needs
The first displacements of cylinders when stretching out, C mouthful two-bit triplet magnetic valves obtain electric commutation, and A, B mouthfuls of two-bit triplet magnetic valves are powered off, compressed air
Into the rodless cavity of the first displacements of cylinders of three cylinders, piston rod is promoted to stretch out, when going to end of travel to the first displacements of cylinders, i.e.,
Middle position, three cylinders are pushed to vertical position by bin gate is rotated, if now powering off C mouthfuls of two-bit triplet magnetic valves, three gas
Cylinder stops in this position, and rotation bin gate is vertical, and the spreading in feed opening full duration direction can be achieved；If in three cylinders are reached
Continue to keep C mouthfuls of two-bit triplet magnetic valves to obtain electric and A mouthfuls of two-bit triplet magnetic valve power-off behind position, and make B mouthfuls of two-bit triplets simultaneously
