Technical field
The utility model relates to a kind of milling machine of road construction construction field, particularly relates to the low pressure watering adjustable systems of a kind of milling machine milling machine when the milling operation.
Background technology
Milling machine low pressure sprinkler system can guarantee sufficient water to the milling and planing drum external surface, milling material and collection, unloads belt and carries out effective spray water, thereby eliminate dust effectively, satisfies environmental requirement; Cool off the milling cutter simultaneously, improve the milling performance and prolong life-span of milling cutter.
At present, both at home and abroad milling machine low pressure sprinkler system is made up of water tank, water inlet stop valve, water filler, low-pressure pump, electromagnetism water valve, milling and planing drum water injector, sprinkler head, gather materials belt water injector and discharging belt water injector usually, can not keep best injection flow rate, it is insufficient to occur watering easily, and causes the milling cutter life to descend.The wasting phenomenon that perhaps occurs water easily, causing shutdown to add the waterside number increases, thereby shortens the effective operation time of machine, reduces operating efficiency.
The utility model content
Problem to be solved in the utility model provides a kind of milling machine when the milling operation, and is according to the different work operating mode, on-the-spot stepless adjustable by regulating in the reducing valve pressure realization watering amount certain limit.Guarantee not only milling and planing drum effectively to be sprinkled water but also to avoid excessive water spray, keep best injection flow rate, can prolong the effective operation time of machine, operating efficiency is significantly improved.
In order to solve the problems of the technologies described above, the milling machine low pressure watering adjustable systems that the utility model provides, comprise water tank, water inlet stop valve, water filler, low-pressure pump, electromagnetism water valve, milling and planing drum water injector, sprinkler head, the belt water injector that gathers materials, discharging belt water injector, hydraulic motor, before described milling and planing drum water injector reducing valve is installed, the water inlet of reducing valve is in parallel with described belt water injector and the described discharging belt water injector of gathering materials.
Described low-pressure pump is a centrifugal water pump.The flow and the discharge pressure of centrifugal water pump are inversely proportional to.Low-pressure pump is by fluid motor-driven.
Described reducing valve is a piston reducing valve.Reducing valve delivery port pressure is manual adjustments.
Adopt the milling machine low pressure watering adjustable systems of technique scheme, owing to a reducing valve is installed at milling and planing drum water injector water inlet, by regulating the discharge pressure of reducing valve, can realize milling and planing drum water injector watering amount and low-pressure pump water yield certain limit step-less adjustment.
The utility model be a kind of milling machine when the milling operation, according to the different work operating mode, realize the stepless adjustable milling machine low pressure sprinkler system of watering amount certain limit, following advantage is compared with prior art arranged:
1. can keep best injection flow rate during the milling operation, avoid the waste of water.Thereby prolong the effective operation time of machine, operating efficiency is significantly improved.
2. can keep effective cooling, prolong the application life of cutter the milling cutter.
3. by regulating reducing valve pressure, the realization watering is measured stepless adjustable, and is steadily reliable.
In sum, the utility model is that a kind of milling machine is when the milling operation, according to the different work operating mode, by regulating the discharge pressure of reducing valve, the stepless adjustable milling machine low pressure sprinkler system of realization watering amount certain limit.Can guarantee not only milling and planing drum effectively to be sprinkled water but also avoided excessive water spray, keep best injection flow rate, can prolong the effective operation time of machine, operating efficiency is significantly improved.Simple in structure, dependable performance.
Description of drawings
Accompanying drawing is the utility model watering adjustable systems schematic diagram.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Referring to accompanying drawing, water inlet stop valve 2 one ends connect water tank 1, the other end is connected with centrifugal water pump 4 by water filler 3, centrifugal water pump 4 is driven by hydraulic motor 11, the flow and the discharge pressure of centrifugal water pump 4 are inversely proportional to, centrifugal water pump 4 is divided into two branch roads by electromagnetism water valve 5, article one, branch road is connected with milling and planing drum water injector 7 by piston reducing valve 6, milling and planing drum water injector 7 is provided with sprinkler head 8, and another branch road is connected with gather materials belt water injector 9 and discharging belt water injector 10.
The utility model milling machine low pressure watering adjustable systems is pressed principle shown in the accompanying drawing and is implemented, before the milling and planing drum water injector, piston reducing valve is installed, the delivery port pressure of piston type decompression is manual adjustments, and piston reducing valve water inlet and the belt water injector that gathers materials, discharging belt water injector are in parallel.Above-mentioned each element is got final product by the functional requirement installation in position.Illustrate as follows:
When milling machine operation operating mode be asphalt concrete pavement, during road surface thickness≤10cm, can turn down the delivery port pressure of piston reducing valve, reduce milling and planing drum watering amount.Because the increase of reducing valve resistance causes the sprinkler system operating pressure to raise, the low-pressure pump flow is corresponding to be reduced simultaneously.
When milling machine operation operating mode be asphalt concrete pavement, road surface thickness〉during 10cm, can heighten the delivery port pressure of piston reducing valve, increase milling and planing drum watering amount.Simultaneously because the piston reducing valve resistance reduces to cause the reduction of sprinkler system operating pressure, the corresponding increase of low-pressure pump flow at this moment.
