Further, both ends of the groove structure are provided with steps.
Furthermore, a flange structure of the connecting device is provided with a flange hole, and the connecting device is connected with the audio drill through the flange hole, a bolt and a nut.
Furthermore, gaskets are arranged at the contact part of the bolt and the flange of the audio drill and the contact part of the nut and the flange structure of the connecting device.
Compared with the prior art, the utility model has the advantages of it is following:
(1) through the utility model discloses a connecting device can directly transmit the power of audio frequency rig for the drilling tool, realizes creeping into work. The adopted common conventional drilling tool is convenient to purchase in the market and has lower price compared with the special drill rod of the acoustic frequency drill.
(2) The utility model discloses connecting device's one end can directly registrate or threaded connection with the drilling rod, compares in flange joint at the during operation and has reduced installation time, has increased work efficiency, the on-the-spot installation of being convenient for.
(3) The injection hole and the diversion trench can increase the injection function of the drilling tool, and when the soil is polluted, the soil can be repaired by injecting the medicament.
(4) The steps are arranged at the two ends of the groove structure, and the double-shoulder structure is strong in torque bearing, good in interchangeability, not easy to break and wide in application range.

In the figures, 1-connecting means; 2-flange structure, 3-flange hole, 4-groove structure, 5-liquid injection hole, 6-diversion trench, 7-step, 8-acoustic drill bit, 9-drill rod, 10-gasket, 11-bolt and 12-nut.
Detailed Description
The present invention will be further described with reference to the accompanying drawings.
Example 1
As shown in fig. 1, the connecting device 1 of the present embodiment is designed such that one end is a flange structure 2 and the other end is a groove structure 4. Wherein, the flange structure 2 is provided with a flange hole 3 for connecting with the flange end of the audio frequency drill bit. The groove structure 4 is used for connecting a drill rod, and the shape of the groove is matched with the shape of the end part of the drill rod. The inner surface of the groove structure 4 is smooth in the embodiment, and the end part of the drill rod is directly sleeved in the groove structure 4. When the vertical pressure well is built, because the force is vertical downwards, the acoustic drill bit directly transmits power to the drill rod and presses the drill rod downwards, and the sleeved connection mode can reduce the replacement time of the drill rod and increase the working efficiency.
Example 2
As shown in fig. 2, the flange structure 2 of the coupling device 1 of the present embodiment is the same as that of embodiment 1, but the groove structure 4 is provided with threads on the inner surface thereof for screw-coupling with the outer surface of the drill rod, thereby fixing the drill rod in the groove structure 4. When pulling back, because the power is vertical upwards, so adopt the mode of threaded connection, connecting device drives the drilling rod and lifts out from the underground.
The connecting device 1 of the embodiment is also provided with a liquid injection hole 5 and a diversion trench 6, wherein the diversion trench 6 is communicated with the groove structure 4 and is communicated with the hollow structure of the drill rod during working. When the soil needs to be repaired, the medicament is injected from the injection hole 5 and flows into the drill pipe and then flows into the soil.
In order to bear stronger torque, step 7 structures are further arranged at two ends of the groove structure 4, and the groove structure is a double-shoulder structure in the embodiment.
As shown in fig. 3, the flange structure 2 of the connecting device 1 and the flange end of the acoustic drill bit 8 of the present embodiment are connected with the groove structure 4 of the connecting device 1 and the drill rod 9 through a gasket 10, a bolt 11 and a nut 12. The drill rod 9 can be a special audio drill rod or a common conventional drill rod, one end of the drill rod 9 in the embodiment is a male head, and the other end of the drill rod 9 is a female head, so that the drill rod can be used in an overlapping mode according to the drilling depth.
The high-frequency exciting force generated by the acoustic frequency drill bit 8 is transmitted to the drill rod 8 through the connecting device 1 to realize the drilling work. When the back-drawing operation is carried out, the main oil cylinder drives the audio drill bit 8 to move upwards, and the audio drill bit 8 drives the drill rod 9 to move upwards through the connecting device 1, so that the back-drawing operation is realized.
The above embodiments are only the preferred embodiments of the present invention, and these embodiments are all based on the present invention, and the protection scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention should be covered by the protection scope of the present invention.
