Abstract
Provided is water injection control device of a milling machine, characterized in that: a motor drives a water pump directly; water from an outlet of the water pump is delivered to a nozzle and injected by the nozzle; and an electromagnetic water valve is connected between the water pump and the nozzle. The device has the advantages of intellectualization and humanization. Through automatic control of a water injection system, the service life of the water pump is prolonged; maintenance cost of the whole machine is lowered; and milling machine operators' working environment is improved.
Description
Technical field
The utility model relates to a kind of engineering machinery road-surface milling equipment, particularly relates to a kind of milling machine water spray control device.
Background technology
Milling machine at operation process actual be exactly milling cutter satisfy the need the layer the rotary cutting process.In working angles, certainly will cause the wearing and tearing of milling cutter, be cut the waste material that gets off simultaneously and under the high speed rotation of milling cutter, can produce a large amount of dusts.
Effectively reducing the milling machine tool wear and reduce the dust that is produced owing to milling machine in operation process is to improve the milling machine milling cutter life-span and increase work efficiency, improve the milling machine operator and the key of less important work personnel working environment.
The milling machine conventional products is at the indoor increase water injector of milling, is constantly pumped water under high pressure and be sprayed onto milling indoor in the milling cutter course of work by water pump.The method can reach the wearing and tearing of minimizing milling cutter and the purpose of the dust that the reduction milling machine is produced in operation process.But water pump is also in running order when water tank lacks water or when not having water in the milling machine operation process, and this will accelerate the wearing and tearing of water pump, certainly will influence the application life of water pump for a long time in the past.
Summary of the invention
The purpose of this utility model just provides a kind of novel milling machine water spray control device to the water pump automatic protection functions can be implemented in lack of water or there be not water the time.
Solution of the present utility model is such: by the motor direct-drive water pump, the water of exit of pump is delivered to shower nozzle, by shower nozzle water is sprayed, between water pump and shower nozzle, be connected with the electromagnetism water valve, be provided with the ECU that exit of pump water spray pressure is detected, ECU control motor or electromagnetism water valve at exit of pump.
Utilize ECU that the water spray pressure of exit of pump is detected, cross when hydraulic pressure and then to represent pump entrance lack of water or water tank lacks water when low, at this moment ECU sends signal automatic cut-off motor power supply and has effectively avoided water pump to remain in operation when lack of water, thereby has prolonged the application life of water pump.The water spray indicator lamp extinguishes when water pump quits work, and in time adds water or pump entrance is cleared up with the caution operator.
The novel advantage of this use is intelligent, hommization.Realized prolonging water pump application life, reduced the complete machine maintenance cost, improved the purpose of milling machine operating personnel's working environment by automatic control water spray system.
Description of drawings
Accompanying drawing is embodiment of the present utility model.
Accompanying drawing 1 is a structural representation of the present utility model.
Accompanying drawing 2 is schematic diagrams of ECU 3.
The specific embodiment
The utility model directly drives water pump 2 by motor 1, the water of water pump 2 outlets is delivered to shower nozzle 5, by shower nozzle 5 water is sprayed, it is characterized in that between water pump 2 and shower nozzle 5, being connected with electromagnetism water valve 4, be provided with the ECU 3 that exit of pump water spray pressure is detected in water pump 2 outlets, ECU 3 control motor 1 or electromagnetism water valves 4.
Water pump 2 is driven by motor 1 in accompanying drawing 1, and low-pressure water enters water pump 2 backs from water tank and flowed out by water pump 2 high pressure chests, directly arrives shower nozzle 5 and is sprayed onto the milling chamber by shower nozzle 5 through electromagnetism water valve 4 backs.ECU 3 is monitored the discharge pressure of water pump 2 outlets at any time, and according to discharge pressure control motor 2 and electromagnetism water valve 4.
ECU 3 is according to water pump 2 delivery port pressure control motors 1 and electromagnetism water valve 4 in the accompanying drawing 2, signal to the signal lamp 6 that is installed on the console simultaneously, if then signal lamp 6 is bright for water pump 2 and electromagnetism water valve 4 operate as normal, if water pump 2 and electromagnetism water valve 4 silence signal lamps 6 go out.Operator can check in time whether whether lack of water or pump intake stop up water tank according to the duty of signal lamp 6.
Work one: at first send the signal drive motor running by operator operation ECU 3, motor 1 drives water pump 2, the delivery port pressure that detects water pump when ECU 3 during greater than 0.3MPa ECU 3 send signal and open electromagnetism water valve 4, electromagnetism water valve 4 is opened water that back water pump 2 pumps, and can directly to be sprayed onto milling by shower nozzle 5 indoor.Thereby play the effect that reduces cutter wear, reduces the milling dust.Signal lamp 6 keeps Chang Liang when water pump and water valve are working properly.
Work two: when the water inlet saliva filter of water tank lacks water or water pump 2 was stopped up, the delivery port pressure of water pump can be followed reduction.ECU detects the power supply that sends signal cut motor 1 and electromagnetism water valve 4 when the water pump water outlet mouth pressure is lower than 0.3MPa immediately, and at this moment water pump 2 will quit work, and has avoided the wearing and tearing that cause owing to lack of water.Synchronous signal lamp 6 extinguishes.
