The other ends of the two push rods are connected by a handle, which is convenient for maintaining the balance of the push piece when advancing. With the handle , the operation is more convenient.

There are two through holes and two push rods, and the two through holes are relatively arranged on the top wall of the drill tube. The other ends of the two push rods are respectively connected to a guide ring through a connecting rod. The guide ring sleeve Connected to the guide rod, the guide rod is arranged on the top wall of the drill barrel, through the mutual cooperation of the guide rod and the guide ring, the push piece will not be inclined during the downward push, and the push piece and the drill barrel The gap of the side wall will be very small, and the stubborn soil or stones and other things remaining in the drill barrel can be pushed out more thoroughly.

The utility model is suitable for survey institutes, research institutes, construction units, etc., and these units need to use drill pipes for drilling or sampling. The improved technical principle of this utility model is simple, easy to operate, cost-effective, and there is no safety problem. The simple improvement can greatly facilitate the cleaning work of the drill tube after use and improve work efficiency, so it can be widely used.

Detailed ways

Now in conjunction with accompanying drawing, the utility model is described in further detail. These drawings are all simplified schematic diagrams, and only schematically illustrate the basic structure of the utility model, so they only show the configurations related to the utility model.

As shown in Figure 1, a kind of improved drill pipe device, comprises the cylindrical drill pipe 5 that one end is opened, and the top of described drill pipe 5 is provided with the through hole 4 that runs through the top wall of drill pipe 5, and push rod 2 passes through Through the through hole 4, one end of the push rod 2 extending into the drill barrel 5 is connected with a push piece 6 for pushing out the residual soil or stones in the drill barrel 5, and the plane where the push piece 6 is located is the same as that of the drill. The plane where the top wall of the cylinder 5 is located is parallel; by applying force to the push rod 2, the push rod 2 drives the push piece 6 to squeeze downward, and the stubborn soil or stones remaining in the drill cylinder 5 can be pressed out , which greatly facilitates the cleaning work of the drill barrel 5 after use.

There are two through-holes 4 and two push rods 2, and the two through-holes 4 are oppositely arranged on the top wall of the drill tube 5.
