摘要：本发明提供了一种多钻头切换开采装置,旨在解决现有钻井技术无法高效切换钻头,并且无法实现钻头与掘进管的顺利对接以及掘进管的高效续接的问题。通过设计对接机构、钻头更换机构、掘进管续接机构等,本发明能够实现在钻井过程中钻头的高效更换与掘进管的续接,从而提高钻井作业的效率和安全性。本发明的技术方案简化了操作流程,提升了钻井作业的自动化水平和作业深度,具有较好的市场应用前景。The present invention provides a multi-drill bit switching mining device, which aims to solve the problem that the existing drilling technology can not efficiently switch the drill bit and can not achieve the smooth docking of the drill bit and the tunneling pipe and the efficient connection of the tunneling pipe. By designing a docking mechanism, a drill bit replacement mechanism, a tunneling pipe connection mechanism, etc., the present invention can achieve efficient replacement of the drill bit and the connection of the tunneling pipe during the drilling process, thereby improving the efficiency and safety of the drilling operation. The technical solution of the present invention simplifies the operation process, improves the automation level and operation depth of the drilling operation, and has a good market application prospect.
