The specific embodiment
To combine the accompanying drawing among the utility model embodiment below, the technical scheme among the utility model embodiment is carried out clear, intactly description, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.
Shown in Fig. 1-1, Fig. 2-1 and Fig. 4-1, the utility model provides a kind of drilling tool embodiment to comprise: comprise brill top 1, brill bucket 5, the end mechanism 6 of unblanking, bore the end 8, unload soil pressure dish 7 and hydraulic drive mechanism.Wherein, unload soil pressure dish 7 and be used for the dregs that bucket 5 is bored in extruding downwards; Unload and be provided with through hole 71 in the soil pressure dish 7, the perisporium that unloads soil pressure dish 7 is provided with breach 72; Through hole 71 is used to pass the depression bar 61a of end mechanism 6 of unblanking; Breach 72 is corresponding with brill bucket 5 interior discharge orifices.
Hydraulic drive mechanism is used for driving and unloads soil pressure dish 7 motion downwards in boring bucket 5, specifically can comprise: hydraulic stem 2, hydraulic oil container 3 and hydraulic jack 4; Wherein, hydraulic oil container 3 is positioned at and bores bucket 5, and is fixed on the below of boring top 1; Hydraulic stem 2 is communicated with hydraulic oil container 3, and is positioned at a side of boring top 1; Hydraulic jack 4 is communicated with hydraulic oil container 3, and is positioned at the below of hydraulic oil container 3; The end of hydraulic jack 4 with unload soil pressure dish 7 and be fixedly connected.Preferably, the end of hydraulic jack 4 is connected with the center fixation of unloading soil pressure dish 7.
Preferably, be provided with the through hole 31 of perisporium sealing in the hydraulic oil container 3, be used to pass the depression bar 61b of end mechanism 6 of unblanking.Depression bar 61b is positioned at the opposite side that bores top 1, like this, and the installing space that the depression bar 61b that can not influence the end mechanism 6 of unblanking is set that can hydraulic oil container 3.It is understandable that depression bar 61a and depression bar 61b also can wholely be provided with, and do not influence purpose of design of the present invention.
Preferably, unblank the height of depression bar 61b under stress not of end mechanism 6 greater than the height of hydraulic stem 2 under stress not.The height reference substance can be for boring top 1 or other objects.
Preferably, unload soil pressure dish 7 and be the steel disk of outer shroud rubber ring, to increase the plasticity of platen.
Preferably, be set with back-moving spring 21 on the hydraulic stem 2.
The course of work of above-mentioned drilling tool is explained as follows: after drilling bucket is carried brill; The depression bar 61b and the hydraulic stem 2 of end mechanism 6 have certain height poor owing to unblank; The unit head platen can be pressed onto the top (hook 62 of the end mechanism 6 of unblanking is in state shown in Fig. 4-1, promptly bores the end 8 and is pinned by hook 62) of depression bar 61b earlier; After compressing into certain stroke, the hook 62 of the end mechanism 6 of unblanking is in state shown in Fig. 4-2.At this moment, bore the end 8 and open, the unit head platen continues to press down, and can be pressed onto the top of depression bar 61b and the top of hydraulic stem 2 simultaneously; Along with hydraulic stem 2 to lower compression, the hydraulic jack of hydraulic oil container 3 bottoms 4 can stretch out (shown in Fig. 1-1, Fig. 2-1 and Fig. 3-1) under the effect of oil pressure, promote to unload soil pressure dish 7 extruding dregs (soil on the bucket wall is also had squeezing action) downwards; Because it is opened that bore the end 8 this moment, dregs is extruded and bores bucket 5, so far accomplishes slag dumping.When hydraulic stem 2 carries out certain stroke (being generally 5cm-10cm), can accomplish the native process of unloading, straighten one out and ease out his anxiety the state of hook 62 of latch mechanism 6 this moment shown in Fig. 4-3.After unloading the soil completion, back-moving spring 21 can discharge back reset condition with hydraulic stem 2, and correspondingly, hydraulic jack 4 also can be regained, and its state is shown in Fig. 1-2, Fig. 2-2 and Fig. 3-2; It is understandable that can not make hydraulic jack 4 and unload soil pressure dish 7 and regains fully like spring 21, when drilling bucket crept into dress soil again, dregs also can and unload soil pressure dish 7 and squeeze back original contraction state hydraulic jack 4.
It will be appreciated by those skilled in the art that; Unload soil pressure dish 7 through hydraulic-driven and in boring bucket 5, move downward the defective that can help to solve existing drilling bucket bucket wall slag dumping difficulty; Depression bar 61b and hydraulic stem 2 difference in height under stress not mainly be for satisfy unloading soil pressure dish 7 and squeezing soil downwards before; Open and bore at the end 8, realized when squeezing soil, unloading the function of soil, be preferred version; Squeeze native front opening and bore the end 8 for being implemented in, depression bar 61b and hydraulic stem 2 difference in height under stress not satisfies and is pressed onto the hydraulic stem 2 front openings brill end 8 at the unit head platen and gets final product; Certainly can also suitably increase the difference in height between the two, promptly drive this hydraulic jack 4 again after an end distance leaves opening to advance again after boring the end 8.In addition, above-mentioned hydraulic drive mechanism can also adopt other form of structure, and can't help the unit head platen provides original driving force.Above-mentioned drilling tool structure can be applied to various rotary drilling rigs.
The utility model drilling tool unloads the soil pressure dish through hydraulic-driven and pushes dregs downwards, helps to solve the defective of clay slag dumping difficulty on the existing drilling bucket bucket wall, improves efficiency of construction, and simple in structure, installation facility, widely applicable; Preferably,, can realize automatic slag dumping through depression bar and the hydraulic stem difference in height under stress not, the drilling efficiency that improves drilling tool with creep into quality.
More than be merely the preferred embodiment of the utility model, or not all within the spirit and principle of the utility model in order to restriction the utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
