Problems solved by technology
[0003] The general drilling method is to adopt the ground power drilling method: that is, the power drive device is placed on the ground, the power device is connected with the connecting rod, and then the drill bit is connected with the connecting rod, so that the power device drives the drill bit to drill through the connecting rod. It can continuously deepen the depth, and it is necessary to stop adding a connecting rod at a certain distance, which is very troublesome and the drilling speed is very slow, and in deep drilling that is too deep, after adding too many connecting rods, the overall length If it is too long, the driving force and connecting force of the connecting rod are very fragile, and it is easy to twist the connecting rod, which leads to the failure of drilling

Embodiment Construction
[0010] A jointless drilling head will be further described below in conjunction with the accompanying drawings.
[0011] The figure is a side view of the structural principle of a jointless drilling head. In the figure, the entire jointless drilling head has a long shape and drills vertically downward. The device bottom among the figure is drill bit (10), and this drill bit (10) takes on the important task of playing the pioneer, and any hard rock formation that stops in the front is rotated into powder at a high speed and pushes away. Next to drill bit (10) among the figure is big motor (6), drives drill bit (10) by drill bit rotating shaft (8). Next to the upper part of the big motor (9) is the small motor (7), the rotating shaft (4) of the small motor (7) drives the upper propeller (3), and the propeller (3) relies on the powder generated earlier as the medium for high-speed rotation , produce thrust downwards, for the drill bit (10) of bottom can advance to deeper layer. ...

The invention relates to a connecting rod-free drilling head, which mainly comprises a drill bit, two electric motors, a propeller, a rotating shaft, a detection equipment box and a sling, wherein the drill bit is directly driven at high speed by the large electric motor to downward drill to produce powder; the propeller is driven by the small electric motor to rotate at high speed, and downward thrust is generated to drive the drill bit on the lower part to downwards and movably drill in a way that the powder is taken as a medium; a sleeve sleeving the rotating shaft is arranged on the detection equipment box; the sling is connected to the detection equipment box in a lifting way. According to the connecting rod-free drilling head, a heap of connecting rods are replaced by the sling and a conductor wire, so that the drilling depth and speed are increased.
Description
technical field [0001] The invention relates to a drilling bit, in particular to a deep drilling bit without a connecting rod, and belongs to the technical field of drilling. Background technique [0002] In the field of drilling, such as drilling deep water wells, the depth of groundwater sources in some places exceeds one kilometer. These places are mainly in areas with high mountains or plateau areas. It is difficult to obtain water sources for drilling in these areas; for example, in some oil fields, The depth of drilling is even deeper, some kilometers or even tens of kilometers. Such a deep drilling is unimaginable. Generally, only some countries with advanced technology can reach such a layer of drilling. [0003] The general drilling method is to adopt the ground power drilling method: that is, the power drive device is placed on the ground, the power device is connected with the connecting rod, and then the drill bit is connected with the connecting rod, so that the...
