With reference to layout shown in Figure 5, as can be seen, have the first variable volume chamber 30 and the second variable volume chamber 31, the flexible connecting

member

32 and 33 of tire-like comprises each that the piston of parts 34 and 35 and spindle moving part 36 link up respectively simultaneously, in big multioperation, the motion amplitude of imagination is less relatively.Preferably from several millimeters to several centimetres of some branches, if still acoustics is big first watch, then motion amplitude can be bigger for their scope.Frequency can be from several hertz to several KHzs.

Each chamber is by piston element 34 or 35 gauges, and preferably, each in the described piston element comprises peripheral pressure drop groove and do not have piston ring.This is for fear of having certain lubrication owing to vibrate the fluid that ring damages and permission is supplied with that is caused between piston and corresponding static valve body 37 and 38.As can be seen, each

static valve body

37 or 38 is cooperated mutually by opening and with corresponding rotary valve element or

rotary valve shaft

39 and 40, so that allow fluid to flow into or outflow near

variable volume chamber

30 or 31 from it.

Have a passage vertically in each rotary valve element 39, this passage is radial opening thus, and is preferably used for the fluid that turns back to collection chamber is discharged, and it just can return (for example by pumping) as shown in Figure 5 like this.The oil inlet pipeline is shown as the valve control device (valving arrangement) that is supplied in

rotary valve element

39 or 40 outsides by passage.

The fluid of a separation is supplied with (not shown among Fig. 5) and is used for hydraulic motor 41, and this hydraulic motor 41 is operated for each

rotary valve element

39 and 40 by element 42 and annular driving band or equivalent 43.This hydraulic motor receives a fluid and supplies with, and with regard to shuttle was moving, this fluid was supplied with and preferably separated with the fluid displacement of supplying with for the purpose that encourages acoustic heads.

As can be seen, the device that preferably includes

parts

41,42 and 43 is positioned on slide block or the sliding part 44 with respect to framework 45, and this framework 45 supports acoustic heads directly or indirectly.Framework 45 itself can be arranged to the slidably support that is positioned on supporting track or other structure 46, so that it is preferably operated with respect to structure 46 in limited field.

If desired, slide block 44 and track or other structure 46 can link up.

Figure 6 shows that the acoustic heads with drill string axle or equivalent 47, this drill string axle is suitable for being rotated by the annular driving band/chain or the equivalent 48 that are driven by hydraulic motor 49 (hydraulic pressure supply of Fen Liing once more).The optional rotation of axle 47 will be rotated or be handled the drill string that is connected thereto, and axle or equivalent 47 can (directly or indirectly) vibrate under the action of the close piston of acoustic heads or compensation device simultaneously.

This close piston, piston component or compensation device preferably are supported to feasible removable at least in the vertical with respect to framework 45, and some guiding connectors preferably are provided for this reason.For example, the connecting rod 50 of acoustic heads either side and 51 can be connected to acoustic heads and be connected to framework 45 by 54 and 55 by pivot 52 or 53.Meanwhile, also preferably together with

air bag

58 and 59 motion is limited by compression spring 56 and 57 (or air bag), this provides buffering or damping effect between acoustic heads and framework 45 (also having support or supporting member 44 and 46 thus).

Therefore as can be seen, this connection has allowed certain similarity of dog bone (dog bone) connecting rod rotation, and meanwhile allow the certain on the whole axial displacement of acoustic heads, and spindle moving part/shuttle (shuttle) 36 can directly not contact with 46 with framework and/or slide block or support 44, this with accompanying drawing in unshowned flexible actuator and flexible pipe and/or other to connect the structure that is caused different.

Preferably, all connectors (comprising hydraulic pressure) all are flexible pipes of flexible antivibration, disconnect unintentionally avoiding.

Acoustic heads of the present invention can drilling hammer (jackhammer) mode even be not adjusted at drill string under the situation of resonance start working.After this control can be: (a) speed of rotary valve (rotor); And/or (b) volume of fluid (for example oil).This can change frequency, but still allows irrespectively to increase power with drill string length.Drill string can make moment of torsion and pressure placed on it and can not influence the moving acoustic heads spindle moving part of resonator or shuttle.Very strong drilling control so just is provided.

Supply with rotor control system independently with the oil of spindle moving part, be mainly used in the vibration isolation of the acoustic heads of acoustic vibration, the framework in the frame mounting and the short distance of oily vibratility adjustment brought significant advantage.

Now will be by the cycling shown in the unit describe Fig. 7 to 9A with aforementioned fluid ability.Note that Fig. 1 to 9A apparatus shown is about 1.5m, shuttle is moving to be the magnitude of 0.1mm to 15mm (amplitude), and operating parameter influences amplitude.

Operation can be directly to be the motion of millimeter scope, as relate to the situation (A) (being Fig. 8 ', Fig. 9 ' etc.) of Fig. 7, but alternately, it also can be the situation (B) shown in Fig. 8 A and 9A, every kind of situation all need have accumulator in oil circuit, with the required instant motion of the instantaneous state that allows following Fig. 9 and Fig. 8.

The device of supposing according to the present invention form shown in Figure 10 to 13 is preferably driven by the hydraulic system from for example excavator (or other vehicle or standing prime mover), and therefore related here various pressurised fluid sources and container is preferably pressurised fluid source and the container that this device can be connected to the supply excavator on it.Also preferably, since may require independently to rotary valve or one of (and timing by each other or connection thus synchronously) end regions of hydraulic-driven being provided and independently fluid alternately being packed into each chamber, in this pressurized hydraulic fluid enters the influx of this device by this closure member and/or resistance valve etc., shunting can be arranged.

In the embodiment shown in fig. 10, piston 60 has the extension 61 that is turned to the permission axially-movable by axle journal.Piston and axle journal are circular cross section and/or whether allow them to rotate in the chamber that is limited by chamber combination 62 be inessential.

From embodiment illustrated in fig. 10, can find out to have the first chamber end regions 63 and the second chamber end regions 64 that can lead to

import

65 and 66 respectively.

Do not have on the same radial zone rotary valve 66 of

opening

67 and 68 be positioned as basically around with the axis rotation of the stroke axis quadrature of piston 60.

As can be seen, one of these openings 68 (being labeled as 68A) make the liquid feeding chamber of the pressurization chamber 69 of fluid supply assembly open for to be connected with chamber end regions 63, owing to out-phase state (promptly exist when first import 65 is opened second import 66 is remained the zone of closing 67), do not enter the passage of chamber end regions 64 simultaneously via second import 66.The reverse situation of front will allow alternately to fill each chamber end regions.

As shown in figure 10, have first outlet opening that is used for chamber end regions 63 or export 70 and be used for chamber end regions 64 second the outlet 71.Under the situation that wherein these ports are often opened as shown in figure 10, preferably the device except second rotary valve (in this case for having the plate of opening 72 and 73) guaranteed via the speed of the liquid inlet of opening 68 and

port

65 or 66 will be always greater than by as the respective openings 72 of the part of hydraulic circuit or any rate of discharge of 73.

It will be appreciated by those skilled in the art that how fluid supply assembly 74 can enter chamber 69 with the hydraulic fluid supply that enters, and fluid flows in

chamber end regions

63 and 64 one or another thus, and thus by outlet (in an example be 70 and 72 and be 71 and 73 in another example) turn back to for example pumping system of excavator, like this, as possibility is desired, this device just can be connected to hydraulic motor, driving rotary valve 66, thereby hydraulic fluid can turn back to chamber 69 or from its shunting.

More preferred form of the present invention is shown in Figure 12.Be similar to Figure 10, it has piston 75 and

axle journal extension

76 and 77, for example can be thereby limit by the

chamber end regions

78 and 79 of rotary valve 80 controls, and the opening of this rotary valve and non-peristome are arranged in the mode shown in the embodiment that is similar to Figure 10.Assembly 81 with chamber 82 is suitable for receiving pressurized hydraulic fluid and optionally allows it to be moved in

chamber end regions

78 and 79 and enter another then.

Thereby has permission with respect to the injection homophase or out of phase with the effect that then from another discharge piston shuttle moved of hydraulic fluid from

chamber

78 and 79 with the rotary valve element 83 that the rotation of rotary valve 80 is in step with.Discharge rotary valve 83 preferably with rotary valve 80 with the speed rotation, and the interval of its opening is suitable for the outlet of each

chamber

78 and 79.

Figure 11 shows the layout of these openings best, one of them port 84 is closed by not aiming at the opening 85 of input rotary valve 80, the outlet 85 of same chamber end regions 86 is simultaneously aimed at opening 87, to allow to export the chamber 88 that flows to into fluid collection assembly 79, it is directed returning by for example excavator thus, uses to be used for pumping circulation.

The layout of Figure 13 shows motor 90 (using hydraulic motor ideally) with the bench test form, it directly drives a driven unit, this driven unit is suitable for rotating the first rotary valve (not shown), a chain belt 91 also drives another rotary valve (not shown) by second chain belt 93 conversely by pony axle 92 simultaneously, thereby the suitable vibration of stretching into axle journal output element 94 (causing by the shuttle of piston is moving) is provided.

Therefore, in operation, suitable adjusting can produce required vibration.If suppose excavator has provides the liquid stream and the pressure of substantial constant for device of the present invention ability, and exist shunting, so that a liquid stream can supply to hydraulic motor to realize the rotation of rotary valve, simultaneously another liquid stream at rotary valve regularly or optionally fill the either side of piston under the action that is synchronized with the movement has then been realized very simple control strategy.Like this, compare with previously disclosed any prior art process, make complexity littler, moving component still less and require lower tolerance.

For example, if the import at an end place is closed by its rotary valve,, and will can not produce any effect by being filled into this end regions just then hydraulic fluid can not flow.Yet, on the contrary, can not be such situation, if it is partly or entirely to open at the other end.

So when the input rotary valve was rotated (rotation), hydraulic oil just flowed into piston chamber's end regions and forces the end motion of piston to its stroke.Rotary valve be rotated further and by its regularly or with the synchronization mechanism of another rotary valve, allow to discharge " consumption " flow of pressurized to discharge.Meanwhile or subsequently (perhaps both have concurrently), first rotary valve redirect to the other end of piston with oil, and it forces piston to return conversely.

The hydraulic-driven of being undertaken by Timing Belt (timing belt) means; if rotary valve is slowly rotation (for example 10rpm) as one man; then shuttle is moving very lentamente for piston; if but rotary valve all with the rotation of the speed of for example 100rpm, then piston can be with for example approximately speed motion of per second 200 times.Therefore, by just adjusting at various ground conditions by means of the speed of the fluid that enters hydraulic motor being controlled to handle synchronous rotary valve simply and easily.
