Crawler Type Hydraulic Direct Push Drill Working Principle

Crawler Type Hydraulic Direct Push Drill Working Principle

The crawler hydraulic direct drilling machine is a kind of soil sampling equipment with high sampling efficiency on the market.

Since it is called hydraulic transducing, what is the hydraulic transducing method? In fact, the principle is very simple, crawler rig is an integrated soil sampling rig, this rig will drill frame, power head, hydraulic system, power system and crawler chassis combination of integrated rig. The advantage of this type of rig is that it is robust and self-moving, so that only the underground section and the rig can be manually operated while drilling. And the drill can be adapted to a larger caliber drill pipe for drilling. Their theoretical drilling depth is around 30m, so they also often appear in various site surveys.
The so-called hydraulic direct push is simply to put pressure on the power head through the hydraulic pressure of the cylinder to make the drilling of the power head more efficient, and can have a certain ability to break through the backfill soil layer. The weight of the rig is generally calculated in tons, so the weight of the rig can also be used as a counterweight to pressure the power head, so as to replace the human pressure and better drilling work.

The power head of the hydraulic direct push drill also uses a high frequency vibration situation, but this vibration frequency will be higher. Combined with the downpressure of the powerful hydraulic cylinder and the weight of the rig itself, the drilling efficiency is very high.
