Abstract

The embodiment of the invention provides a rotary excavating drilling rig and an engineering machine and relates to the field of engineering machines. The rotary excavating drilling rig comprises a drilling rig body, a bulldozing plate, a guide structure and a pressure bearing plate. The drilling rig body is provided with a cavity. The bulldozing plate is connected with the guide structure and located in the cavity. The guide structure is movably connected with the drilling rig body and can slide relative to the drilling rig body. The pressure bearing plate is connected with the guide structure, located outside the cavity and used for being in drive connection with driving equipment, so that the driving equipment drives the bulldozing plate to move in the cavity. By means of the rotary excavating drilling rig and the engineering machine provided by the invention, the rock core and slag unloading time can be shortened, operation is convenient and easy, and the rock core and slag unloading efficiency is improved easily; and meanwhile, excessive abrasion of components is avoided, and the service lives of the rotary excavating drilling rig and the engineering machine are guaranteed.

Description

technical field [0001] The invention relates to the field of construction machinery, in particular to a rotary drilling tool and construction machinery. Background technique [0002] When a rotary drilling rig drills into a rock formation, barrel drilling is a more efficient rock breaking method, but sometimes it takes a lot of time to unload the core. When unloading the core, the power head and the drilling rig are constantly rotating forward and backward, the drill pipe is constantly impacted and worn, and the drill pipe and the drill bucket are also constantly collided. In addition, it is necessary to add wooden piles above the drilling tool or put cross steel piles on the ground. After the above steps, the rock core can be taken out from the drilling tool. [0003] Obviously, in the prior art, unloading the rock core and slag takes a long time, is inefficient and complicated, and also increases the wear and tear of the components and reduces their service life.
