AI Technical Summary
The vibrations generated when the drilling rig starts up cause the contact position between the drill rod and the coal mine to shift, affecting the accuracy of drilling.
A positioning device for coal mine drilling, including a positioning component and a dustproof component, was designed. The positioning plate fits against the mine wall, gears mesh, and a dustproof cover prevents dust from splashing, ensuring the stability of the drilling rig and cleaning drill rod particles, thereby improving drilling accuracy and safety.
By using a positioning plate that fits against the mine wall and gears that mesh, the stability of the drilling rig is ensured during the drilling process. Dustproof components prevent dust pollution and clean drill rod particles, improving drilling accuracy and mining efficiency.
