Abstract

The invention discloses various drill bit integrated direct-pushing type sampling equipment. The equipment comprises a working frame body and a main cylinder; the working frame body is provided with aspiral power head and an impact power head, and the spiral power head and the impact power head are connected with the main cylinder and can move up and down along the working frame body; a clamp holder, a rotating shaft and a rotating power head are arranged on the working frame body; the clamp holder is located below the impact power head, is connected with the main cylinder and can move up anddown along the working frame body; the clamp holder is fixed on the rotating shaft; and the rotating power head comprises a motor, a gearbox and a gyrator which are sequentially connected, and the gyrator is arranged below the clamp holder. According to the equipment, rotating drill bits are integrated so that direct-pushing type and rotating impact drilling sampling can be carried out at the same time, and direct-pushing sampling, direct-pressing well building, spiral well building and other work can be completed.

Description

technical field [0001] The invention relates to a direct-push sampling device integrating various drill bits, belonging to the technical field of engineering machinery. Background technique [0002] The soil is highly heterogeneous and concealed, and appropriate drilling methods must be adopted to obtain representative soil samples for analysis of the soil properties of the plot. "Technical Guidelines for Soil Pollution Risk Control and Restoration Monitoring of Construction Land" (HJ 25.2-2019), "Technical Guidelines for Soil Quality and Soil Sampling" (GB / T 36197-2018), "Technology for Collection, Storage and Circulation of Land Survey Samples for Enterprises in Key Industries" "Regulations" and other technical guidelines stipulate that soil samples used for environmental investigations must be undisturbed. [0003] Domestic SH30 drilling rigs generally use mechanical power to repeatedly lift and drop the hammerhead within a certain range with steel cables to provide impa...
