Impact power head and audio frequency power head integrated vehicle-mounted drilling machine

Abstract

The invention discloses an impact power head and audio frequency power head integrated vehicle-mounted drilling machine. The drilling machine comprises a power driving device, a connecting device anda power head device. The power driving device is connected with the connecting device and the power head device. The power head device is connected with the connecting device, and the connecting device can be used for adjusting the state of the power head device. The power head device comprises an audio frequency drill bit and an impact drill bit. When the drilling machine works, the two kinds ofdrill bits can be switched to be used, the defects that when a direct push type technology is adopted, the sampling depth is small and the stratum adaptability is poor are overcome, and the defect that when a single audio frequency technology is adopted, the sampling price is high is also overcome; and under the condition that the maximum stratum adaptability, sampling quality and sampling depth are ensured, optimization of economy and maximization of efficiency can be achieved.

Description

technical field [0001] The invention discloses a vehicle-mounted drilling rig integrating an impact power head and an audio frequency power head, belonging to the technical field of engineering machinery. Background technique [0002] A thorough investigation of the contaminated site is a necessary condition for later evaluation and remediation, which requires advanced drilling equipment as the basis. In soil investigation, due to the heterogeneity of soil, the physical and chemical properties of soil at different depths and in different regions often vary greatly. Change. [0003] Traditional geological exploration drilling rigs often use rotary force or drilling fluid to drill in the process of drilling soil samples. This method has a large disturbance to the soil and is prone to cross-contamination between the upper and lower layers of the soil, which is not suitable for soil sampling in environmental investigations. Require. The direct propulsion technology for soil s...

Problems solved by technology

This technology uses the resonance energy generated by the internal eccentricity of the acoustic frequency drill bit to transmit downward to the drill pipe. The vibration makes the thin layer of soil directly surrounding the drill pipe and the drill bit liquefy, greatly reducing the friction between the drill pipe and the surrounding soil, thereby performing low-disturbance soil sampling. , but audio rig sampling is expensive and the cost is higher
