Abstract

The invention relates to a rotary impact type pneumatic roofbolter. The roofbolter is a drilling tool in a coal mine roadway bolt supporting work. Currently, in the coal mine roadway bolt supporting work, the most common roofbolter is the rotary type pneumatic roofbolter; the current rotary type pneumatic roofbolter only can support a roadway with a hardness f of less than 10 because of uncertainty of the coal mine roadway environment. In order to support the roadway with the hardness f of more than 10, a pneumatic impact structure is integrated into the current rotary type pneumatic roofbolter; and the new rotary impact type pneumatic roofbolter not only can support the tougher roadway, but also can increase a support speed.

Description

Technical field: [0001] The bolter is a drilling tool used in the bolting work of the coal mine roadway. It has very prominent advantages in improving the support effect, reducing the support cost, speeding up the roadway forming speed, reducing the auxiliary transportation volume, reducing labor intensity, and improving the utilization rate of the roadway section. The rock bolt rig is the key equipment for bolt support, which affects the quality of bolt support (the orientation, depth, and diameter accuracy of the bolt hole) and the quality of bolt installation. Background technique: [0002] At present, the most commonly used bolting rig in the coal mine bolting operation is a pneumatic rotary bolting rig. Due to the uncertainty of coal mine roadway environment, the current rotary bolter can only support the roadway with hardness f<10. Invention content: [0003] The pneumatic impact mechanism is integrated on the basis of the existing pneumatic rotary rock bolter h...
