A Portable Mechanical Sound Frequency Vibration Sampling Rig

Abstract

The invention relates to a portable mechanical acoustic vibration sampling drilling rig, comprising a base, a column, an acoustic vibration device, a lifting device, a flexible transmission shaft and a power output device, the column is fixed on the base; the upper end of the acoustic vibration device It is fixed with one end of the wire rope, the lower end of which is connected to the drilling tool, and the other end of the wire rope bypasses the pulley set at the top of the column and is connected to the lifting device; the lifting device is fixed on the column; the audio vibration device The power input end is connected with the power output device through the transmission flexible shaft. In the present invention, the eccentric mechanism is driven by pure mechanical transmission to generate acoustic frequency vibration and exciting force, that is, the acoustic frequency vibration device is driven by the transmission flexible shaft, the vibration frequency and exciting force of up to 200 Hz are generated by the acoustic frequency vibration device, and the exciting force is transmitted to the drill. On the tool, the sound frequency vibration drilling of the drilling tool is realized.

Description

technical field [0001] The invention relates to a portable mechanical sound-frequency vibration sampling drilling machine, which belongs to the drilling equipment for sampling soil in its original state. Background technique [0002] At present, the undisturbed soil sampling is in the loose (soft) cover layer of the Quaternary system, which requires a high sample collection rate, no pollution to the sample, no disturbance, and the original state. Sampling is characterized by shallow hole depth, wide distribution of hole locations, high requirements on the in-situ characteristics of the samples taken, and many of them have the characteristics of inconvenient transportation and short drilling cycle. [0003] Acoustic frequency vibration drilling and sampling technology is a new drilling method, which has the advantages of fast drilling speed, no disturbance and pollution to samples, and good coring effect. It can be widely used in environmental geological survey, scientific d...
