Problems solved by technology

[0003] The deficiencies of this improved structure are: 1. Since the variable speed gearbox and the wind motor are arranged on the head side of the original body, away from the support axis of the legs of the rock drill, the entire weight is concentrated on the head of the rock drill, so when drilling, the entire rock drill is top-heavy The state is difficult to control, and a large eccentric force is generated when rotating, which makes it even more difficult for the staff to control; 2. Since the air intake of the air motor is controlled by an independent valve, it is very inconvenient to operate

Embodiment Construction

[0010] Such as figure 1 As shown, the utility model includes a rock drill body composed of a rock drill shell, an impact part 6 in the shell, an air leg 8, and an operating arm 7, and a rotating part composed of a variable speed gearbox 2 and an air motor 1. The shank of the impact part 6 A gear 5 is processed on the sleeve, an extension shaft 3 is connected to the power output shaft of the transmission gearbox 2, and a transmission gear 4 is installed on the extension shaft 3, and the transmission gear 4 meshes with the shank gear 5; the rotating part is connected with the shell of the rock drill 3. The support axis of the air leg 8 is arranged on the center of gravity of the overall weight of the rock drill; the air intake pipe of the wind motor 1 is directly connected to the control arm 7. on the valve.

Abstract

The invention discloses a pneumatic anchor rod hammer drill, which is mainly characterized in that a power output shaft of a speed change gear box of the prior rotary impact combination hammer drill is connected with a lengthened shaft on which a transmission gear is arranged, and the transmission gear is meshed with a fiber tail sleeve gear; a rotating part and a shell of the hammer drill are corporately fixed on a drill body seat to form a hammer drill whole; a support axis of an air leg is arranged on a gravity line of the weight of the hammer drill whole; and an air inlet pipe of an air motor is directly connected to a valve of an operating arm. The pneumatic anchor rod hammer drill realizes downward shift of the weight of the rotating part, avoids the top-heavy phenomenon, improves the integral stability, avoids direct impact, reduces strong shock during working, and is convenient for a worker to operate.

Description

technical field [0001] The utility model relates to a rock drilling machine. Background technique [0002] The rock bolter is a device used for drilling bolt holes in mine roadway support. The technology relevant to this application is the rotary impact combined rock bolt drill disclosed in Chinese Patent Publication No. CN2864065. Its main structure is improved on the basis of the original pneumatic rock drill. , the rock drill body formed by the air leg and the control arm, the improved structure of the rotary impact combined rock bolt drill disclosed by the publication number CN2864065 is mainly to increase the rotating part. One side of the shell is connected with a variable speed gearbox, and a wind motor is installed at the lower part of the variable speed gearbox. The wind motor drives the shank sleeve to rotate through the speed change gear to realize the functions of impact and rotary cutting. In addition, the air motor is controlled by an independent valve to ent...
