Piston hammer machine drill-in type hammer and drill combined drilling machine

Abstract

The invention discloses a piston hammer machine drill-in type hammer and drill combined drilling machine, and relates to the technical field of drilling machine instruments. The drilling machine comprises a connecting cylinder, a hammer body and a spiral drill bit; the hammer body is in sliding connection with the inner wall of the connecting cylinder; the hammer body is of a cavity structure; a connecting piston is slidably mounted in the hammer body; the connecting piston is fixedly connected with a supporting drill rod; the connecting cylinder and the hammer body are respectively communicated with an air compressor; the spiral drill bit comprises a connecting shaft and a guide blade; the connecting shaft is fixedly connected with the hammer body; and the supporting drill rod is in sliding insertion fit with a connecting opening. The piston hammer machine drill-in type hammer and drill combined drilling machine has the beneficial effects that a torque sensor is used for monitoring a stratum environment to protect the spiral drill bit, so that the spiral drill bit rotates to drill holes when the stratum environment is soft, and the supporting drill rod supports and reinforces the spiral drill bit after the stratum environment is hardened to hammer rocks and the like to perform hammering and drilling operation. Therefore, the drill bit is prevented from being replaced during drilling operation in different stratum environments, the drilling efficiency is improved, and the use is more flexible and convenient.

Description

technical field [0001] The invention relates to the technical field of rapid measurement of finished porcelain products. Background technique [0002] When using a drilling rig for drilling operations, the drilling tool is driven to drill into the ground, thereby driving the drilling tool to break the rock at the bottom of the hole. When drilling in different strata structures, it is necessary to use drill bits of different structures. When drilling in geology, the auger bit is usually used for auger drilling through its helical blades. After encountering hard rock, it is necessary to replace the drill bit and hammer the rock to perform cone drilling. Therefore, during the drilling process, it is necessary to The drill bit is replaced, and the replacement of the drill bit takes a lot of time, thereby reducing the drilling efficiency. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a piston hammer drill-in type h...
