Stagnation-prevention drilling tool capable of reducing stick slip phenomenon through multi-head helical pair

The invention relates to a stagnation-prevention drilling tool capable of reducing a stick slip phenomenon through a multi-head helical pair. The stagnation-prevention drilling tool is installed on the upper portion of a drill bit in a thread connection mode and comprises an upper assembly, a vibration absorption assembly and a lower assembly. The rear end of the vibration absorption assembly is provided with an upper connector assembly, and the front end of the vibration absorption assembly is provided with the lower assembly. Vibration generated in the work process of the tool is absorbed through disc springs connected in series, a pressure cavity and a rubber spring. Through matching of a spiral outer shell and a spiral transmission shaft, the multi-head helical pair is formed. When the reaction torque acting on the drill bit is increased and a stick slip or clamping phenomenon occurs, the spiral transmission shaft rotates backwards relative to the spiral outer shell, and therefore small-amplitude reverse rotation is applied to the drill bit. The reaction force of the ground to the drill bit is lowered, stress of the drill bit reaches balance again, and therefore efficient rock breaking with the drill bit is realized. According to the stagnation-prevention drilling tool capable of reducing the stick slip phenomenon through the multi-head helical pair, the vibration generated during rock breaking with the drill bit can be absorbed, the stick slip phenomenon is reduced, and continuous drilling of the drill bit is guaranteed.
