In 212, dust cover 25 is set between 21 bottom of cylinder body and 22 bottom of plunger, the tensile elongation of the dust cover 25 is not small
In the high-low limit motion amplitude of plunger 22, to ensure that the quick-fried device of nitrogen has the space moved in high-low limit position.
Present invention enhancing breaking capacity, the principle of raising capacity usage ratio are as follows:Mainly nitrogen is utilized in the present invention
Special property:It is compressed when being acted on by external force, energy when nitrogen compresses storage, when unloading external force stopping compression, nitrogen hair
Raw rapid expansion, generates the quick-fried phenomenon of nitrogen.By taking a course of work of the vibration embodiment of the present invention as an example, its principle is introduced.When
Cracking hammer head is after completing to impact object, and by the upward inertia force of vibrator and the rebound effect of object to be broken, plunger is done
Drawback movement, the at this time endoceliac nitrogen of compression cylinder, nitrogen pressure increase, correspondingly acts on the resistance increase on plunger, column
Plug movement velocity slows down until stopping compression, and in compression process, the nitrogen in cylinder chamber not only acts as cushioning effect, can be with
Energy is put aside, that is, converts kinetic energy into the pressure energy of compressed nitrogen, when plunger stops compressing and moving downward, nitrogen moment is swollen
It is swollen, savings energy is discharged rapidly, plunger is acted on by nitrogen expansion power, rapid together with vibrator, cracking hammer head
Accelerate, under the exciting force three superposition of the quick-fried power of nitrogen, gravity and vibrator, act in object to be broken.
The above content is combine specific optimal technical scheme further description made for the present invention, it is impossible to assert
The specific implementation of the present invention is only limited to and these explanations.For those of ordinary skill in the art to which the present invention belongs, exist
Under the premise of not taken off present inventive concept, several simple deduction or replace can also be made, and all do not depart from the essence of the present invention
God and range technical solution and and its improve, should all cover in scope of the presently claimed invention.
