The flushing device is simply and rationally structured and can effectively collect slag.
Description
Technical field
The present invention relates to the drilling tool used in micro-hole drilling process, relate to a kind of be applied to that hydraulic top drives formula unit head can oddments-collecting type flusher.
Background technology
Due to top hydraulic shock crushing function, hydraulic top drives formula unit head and is used widely in miniature pile construction.Because this technology is external introduction, this year is hastily applied at home, exists in drilling process in construction, and at the bottom of flushing hole, the medium of circulation is spray discharge in aperture, cannot effectively collect waste residue and recycle, serious environment pollution.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of structure simple, ingenious, be reasonably applied to that hydraulic top drives formula unit head can oddments-collecting type flusher, this flusher is simple and reasonable, can effectively realize waste residue collecting function.
According to technical scheme provided by the invention: a kind of be applied to that hydraulic top drives formula unit head can oddments-collecting type flusher, it is characterized in that: comprise and wash away mandrel, describedly wash away that mandrel circumferential surface is sheathed washes away shell, the medium inlet washing away shell is connected with the medium channel washing away mandrel, interior drilling rod transit joint with wash away mandrel and be connected, and the bore passage of interior drilling rod transit joint is communicated with medium channel, wash away outer side link and be fixedly connected with outer tube transit joint, slag releasing channel is formed between interior drilling rod transit joint and outer tube transit joint, described slag releasing channel is connected with the overfall washing away shell.
As a further improvement on the present invention, the power intake washing away mandrel described in is connected with the output shaft of hydraulic drive type unit head.
As a further improvement on the present invention, described in wash away shell and wash away between mandrel and be provided with sealing ring, medium inlet and overfall separate by sealing ring between the two.
As a further improvement on the present invention, described in wash away on mandrel and offer slag notch, slag releasing channel, slag notch, overfall three are interconnected.
Compared with prior art, advantage is in the present invention: compact conformation of the present invention, rationally, by sealing ring washing away mandrel and can collect slag and wash away two the mutual airtight spaces formed in casing.Independently import scour medium, and collect the waste residue returned, realize the collection to creeping into waste residue, available protecting creeps into the environment of periphery.The present invention relates to rationally, structure is simple, and use and maintenance is convenient; Simple and reliable realization is collected the waste residue produced in drilling process, effectively overcomes the shortcoming that existing flusher cannot collect the waste residue produced in drilling process, protection of the environment.

Detailed description of the invention
Below in conjunction with concrete drawings and Examples, the invention will be further described.
As shown in Fig. 1 ~ 6, comprise wash away mandrel 1, medium channel 1-1, slag notch 1-2, wash away shell 2, medium inlet 2-1, overfall 2-2, sealing ring 3, interior drilling rod transit joint 4, bore passage 4-1, outer tube transit joint 5, connecting rod 6, slag releasing channel 7 etc.
As shown in Fig. 1 ~ 6, the present invention is a kind of be applied to that hydraulic top drives formula unit head can oddments-collecting type flusher, comprise and wash away mandrel 1, wash away that mandrel 1 circumferential surface is sheathed washes away shell 2, the medium inlet 2-1 washing away shell 2 is connected with the medium channel 1-1 washing away mandrel 1, interior drilling rod transit joint 4 with wash away mandrel 1 and be connected, and the bore passage 4-1 of interior drilling rod transit joint 4 is communicated with medium channel 1-1, wash away link outside shell 2 and be fixedly connected with outer tube transit joint 5, slag releasing channel 7 is formed between interior drilling rod transit joint 4 and outer tube transit joint 5, described slag releasing channel 7 is connected with the overfall 2-2 washing away shell 2.
The power intake washing away mandrel 1 is connected with the output shaft of hydraulic drive type unit head, realizes the rotation of washing away mandrel 1, reaches and transmits the torque of unit head output and the object of ballistic work.
Wash away shell 2 and wash away between mandrel 1 and be provided with sealing ring 3, medium inlet 2-1 and overfall 2-2 separates by sealing ring 3 between the two, and form two mutual airtight spaces, wherein medium inlet 2-1 is for importing scour medium, and overfall 2-2 is for reclaiming waste residue.
Wash away on mandrel 1 and offer slag notch 1-2, slag releasing channel 7, slag notch 1-2, overfall 2-2 three are interconnected.
Interior drilling rod transit joint 4 in product of the present invention is connected to by corrugated thread and washes away mandrel 1 inside, washes away mandrel 1 other end and is used for connecting interior drilling rod, transmits torque and the ballistic work of unit head output, broken cutting hole bed rock soil; Outer tube transit joint 5 is connected to by corrugated thread and washes away mandrel 1 outside, transmits moment of torsion and the ballistic work of unit head output, broken cutting hole bed rock soil, and protects hole wall to prevent from caving in; Connecting rod 6 is bolted and can collects slag and wash away shell 2 and unit head.
As shown in Figure 6, scour medium washes away shell 2 medium inlet 2-1 by collecting slag enters, the medium channel 1-1 of shell 2 is washed away by slag can be collected, arrive at the bottom of hole via interior drilling rod transit joint 4 inside, rinse broken ground, and carry chip via the slag releasing channel 7 between interior drilling rod transit joint 4, outer tube transit joint 5, be back to and can collect the overfall 2-2 that slag washes away shell 2 and overflow, collect.Wherein collect medium inlet 2-1, the overfall 2-2 that slag washes away shell 2 to be isolated in the external world by sealing ring 3, and each self-isolation in inside.Effective sealing can be carried out, convenient collection to scour medium and waste residue.
More than describing is explanation of the invention, and be not the restriction to invention, limited range of the present invention, see claim, within protection scope of the present invention, can do any type of amendment.
