[0002] Bolt drill, also known as anchor drill in some places, is a kind of anchor support equipment for coal mine tunnels. It has outstanding advantages in improving support effect, reducing cost, accelerating tunneling speed, reducing auxiliary transportation volume, reducing labor intensity, and improving tunnel section utilization. Bolt drill is the key equipment of bolt support. It affects the quality of bolt support, the position, depth, and diameter accuracy of bolt hole, and the quality of bolt installation, and also involves the personal safety, labor intensity and working conditions of the operator.

[0003] In the prior art, such as the Chinese patent with publication number CN 220267629 U, a semi-automatic rod changing device for a drilling rig is disclosed. A conveying structure is installed on the front side of a lifting bracket, and a clamping assembly is installed in the first feed tray and the second feed tray in the conveying structure. When the clamping assembly is moved to the front of the first feed tray and the second feed tray of the drilling rig, the circular ring drives the fourth gear and the third gear to rotate through the gear block, and the rotation of the third gear drives the left clamp and the right clamp to automatically rotate and open through the first gear and the second gear, so that it is simple and convenient to place the drill rod in the conveying structure, and the clamping assembly can clamp drill rods of different models, which can effectively expand the scope of use of the semi-automatic rod changing device.

[0004] However, when the above device is performing a rod changing operation, the motor drives the drive shaft to control the rotation of the feed plate, and the drill rods are fed into the drilling rig in turn for rod changing. However, when the motor drives the drive shaft to change the rod, in order to ensure stability during rod changing, the drill rod and the drilling rig need to be stably docked. At this time, the motor needs to stop rotating, and the two need to be relatively still to change the rod. The frequent starting and stopping of the motor will cause a large amount of electron flow inside each time the motor is started, causing the internal temperature of the motor to rise, which may damage the insulating material of the motor, thereby affecting the service life of the motor, thereby affecting the rod changing work. Therefore, a rod changing device for an anchor bolt machine is proposed to solve the above problems. Utility Model Content
