Description
Technical field
The utility model relates to a kind of digging machine disintegrating hammer automatic lubricating systems, belong to excavating machinery technical field.
Background technique
Currently, when excavator crushing operation, for quartering hammer lubrication using manual filling formula, when filling, is time-consuming and laborious, and
Butter filler amount not easy to control and filling period, the problems such as being thus easy to appear quartering hammer insufficient lubrication, corrode.
Utility model content
To solve the deficiencies in the prior art, the purpose of this utility model is to provide one kind being capable of self-lubricate and lubrication
A kind of adjustable digging machine disintegrating hammer automatic lubricating system of frequency.
In order to achieve the above objectives, the utility model adopts the following technical solutions:
A kind of digging machine disintegrating hammer automatic lubricating system, characterized in that including butter filler, reversal valve, quartering hammer, institute
It states quartering hammer and is equipped with actuator port A and actuator port B, the actuator port A connection oil inlet pipe, actuator port A is also connected with commutation
First actuator port F of the valve and control port G of reversal valve, the actuator port B connection oil return pipe, the second of the reversal valve
The control terminal J of actuator port H connection butter filler, the actuator port K of the butter filler are connected by butter filler pipe
The screwdown greaser C of quartering hammer.
As a kind of prioritization scheme, it is equipped with and subtracts between actuator port A above-mentioned and the first actuator port F for connecting reversal valve
Pressure valve.
As a kind of prioritization scheme, reversal valve above-mentioned is 2/2-way pilot operated directional control valve.
As a kind of prioritization scheme, the commutation of reversal valve above-mentioned triggers pressure adjustable section.
As a kind of prioritization scheme, butter filler above-mentioned is hydraulic control plunger type butter filler.
As a kind of prioritization scheme, the operating pressure of pressure reducing valve above-mentioned is adjustable.
The utility model it is achieved the utility model has the advantages that
When quartering hammer work, hydraulic fluid pressure pushes change-over valve core to move to right, and hydraulic oil pushes the column of butter filler
Plug moves to right, and fills butter to quartering hammer；When quartering hammer stops working, reversal valve under the action of the spring, hydraulic oil and butter
Charging machine disconnects, and plunger is slack, and butter stops filling.The commutation triggering pressure of reversal valve is adjustable, when triggering pressure
When low, the working frequency of butter filler is higher, it might even be possible to all fill butter in entire shattering process；When triggering pressure is high
When, butter is only just filled when system pressure is high, the operating pressure of pressure reducing valve is adjustable can be increased entirely to a certain extent
The adjustable range of system pressure, the fluctuation of pressure when can also reduce quartering hammer work.
Detailed description of the invention
Fig. 1 is the utility model principle figure；
The meaning of appended drawing reference in figure: 1- oil inlet pipe；3- pressure reducing valve；6- reversal valve；8- butter filler；9- butter adds
Note pipe；10. quartering hammer；11- oil return pipe.
Specific embodiment
The utility model is further described with reference to the accompanying drawing.Following embodiment is only used for clearly illustrating this
The technical solution of utility model, and cannot be used as a limitation the limitation protection scope of the utility model.
A kind of digging machine disintegrating hammer automatic lubricating system as shown in Figure 1:, including it is butter filler 8, reversal valve 6, broken
Hammer 10, quartering hammer 10 are equipped with actuator port A and actuator port B, and actuator port A connection oil inlet pipe 1, actuator port A, which is also connected with, to be changed
To the first actuator port F of the valve 6 and control port G of reversal valve 6, actuator port B connection oil return pipe 11, the second of reversal valve 6
The actuator port of the control terminal J of actuator port H connection butter filler 8, butter filler 8 are broken by the connection of butter filler pipe 9
The screwdown greaser C of broken hammer 10.
Since the operating pressure of quartering hammer 10 is usually larger, and typically larger than cracking pressure needed for reversal valve 6, therefore
It is preferred that actuator port A and connect reversal valve 6 the first actuator port F between be arranged pressure reducing valve 3, on the one hand by oil inlet pipe 1 to
The pressure of the control port G of the first actuator port F and reversal valve 6 of reversal valve 6 reduces, and on the other hand also makes the pressure of the above process
Power tends towards stability, and the fluctuation that can reduce pressure when quartering hammer 10 works subtracts in order to better meet above-mentioned requirements
The operating pressure of pressure valve 3 is preferably adjustable.
The reversal valve 6 of the present embodiment is 2/2-way pilot operated directional control valve, while in order to meet different duty requirements, being commutated
The commutation triggering pressure of valve 6 is preferably adjustable.
The preferred hydraulic control plunger type butter filler of butter filler 8.
When work, the pressure that hydraulic power supply (being often referred to hydraulic pump) generates enters to the work hydraulic fluid port A of quartering hammer 10, simultaneously
Also the actuator port D of pressure reducing valve 3 is entered to, at this moment quartering hammer 10 is started to work, and pressure reducing valve 3 plays the role of decompression and pressure stabilizing,
Pressure after adjustment is sent to the first actuator port F and control port G of reversal valve 6 by its actuator port E, at this moment,
Control port G opens reversal valve 6, i.e. the second actuator port H is connected in the first actuator port F, and hydraulic oil flows to butter filler 8
Control terminal J, hydraulic oil push butter filler 8 plunger move right, due to butter filler 8 plunger on the right side of be filled with Huang
Oil, therefore butter enters to the screwdown greaser C of quartering hammer 10 under the pressure of hydraulic oil by butter filler pipe 9.Due to subtracting
Pressure valve 3 and the operating pressure of reversal valve 6 can be adjusted, therefore can satisfy different duty requirements.When quartering hammer 10 stops
When only working, reversal valve 6 disconnects under the action of itself spring, and butter filler 8 stops working.The commutation of reversal valve 6 triggers
Pressure is adjustable, and when triggering pressure is low, the working frequency of butter filler 8 is higher, it might even be possible in entire shattering process
All filling butter；When triggering pressure is high, butter is only just filled when system pressure is high.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, without deviating from the technical principle of the utility model, several improvement and deformations can also be made, these change
It also should be regarded as the protection scope of the utility model into deformation.
