AI Technical Summary
Technical Problem
The existing small-scale support-type rock drilling machine is not convenient for adjusting the drilling angle, and the manual adjustment accuracy is low, resulting in errors in the drilling position and the need for re-drilling.
Method used
A blasting drilling device for open-pit coal mines is designed. The drilling angle can be automatically adjusted through the cooperation of a motor-driven gear system and a brake block, and the device is locked and fixed through the close fit between the brake block and the brake wheel.
Benefits of technology
It makes it easier to adjust the drilling angle, improves the accuracy of the drilling position, and reduces the number of times to re-drill.

Abstract
The utility model discloses an open pit coal mine blasting drilling device which comprises a small support type rock drilling machine, the bottom of the small support type rock drilling machine is movably connected with a containing box through a pin shaft, the bottom of the inner wall of the containing box is fixedly connected with a motor, and the output end of the motor is fixedly connected with a transmission rod. And the surface of the transmission rod is movably connected with a limiting block through a bearing. The motor is started, the output end of the motor drives the gear to rotate, the gear drives the semicircular toothed bar and the small support type rock drilling machine to rotate clockwise with the pin shaft as the circle center, the drilling angle of the small support type rock drilling machine is adjusted, the electric telescopic rod is started after adjustment is completed, and the output end of the electric telescopic rod drives the brake block to move downwards. And at the moment, the small support type rock drilling machine can be locked and fixed, so that the effect of conveniently adjusting the drilling angle is achieved.
