Sampler

Abstract

The invention relates to a sampler, and belongs to the technical field of sampling. The sampler comprises a handle, an operating platform, an external drilling barrel, height scales, a small horizontal liquid bubble, a sample discharging groove, a vertical shaft, a drill bit, a drill bit sampling hole, a rotating buckle, a longitudinal sampling ring knife, a lug clamping groove, a transverse sampling hole, a transverse sampling ring knife, sawteeth, a piston-type tail piece, a tail portion lug, a thread, a bottom rotating gear, a bottom control gear, a bottom rotating gear fixing shaft, a sampling rod, a sampling rod handle, a sampling rod moving groove, a sliding key, a spring ball, a spring ball clamping groove, a turning gear, a transverse control gear, a longitudinal adjusting gear, a longitudinal adjusting gear handle, a longitudinal adjusting gear fixing shaft, a compaction sensor, a humidity sensor, a wire, a data display setup screen, a battery and a sample pushing needle. By the adoption of the sampler, spot sampling can be guaranteed, and disturbance to surrounding samples is reduced; transverse sample discharging and longitudinal sample discharging are independent of each other, and sample discharging is thorough. The sampler has the advantages of being reasonable in structure, convenient to operate and capable of saving time and labor.

Description

technical field [0001] The invention relates to a sampler and belongs to the technical field of sampling. Background technique [0002] The sampler is used to lift the test sample as a sample to understand its properties. The sampling process is a dynamic process of secondary disturbance and destruction. The traditional hand-held sampler needs to lift the sampler when extracting samples, which may have the following defects: [0003] 1) When the traditional sampler takes out the sample, it needs to lift the sampler, which is laborious to operate, and at the same time, it is easy to disturb the lower layer of the sample and affect the accuracy of the measurement data; [0004] 2) The traditional sampler can only sample vertically, without horizontal sampling, and cannot measure the data of the three-dimensional space state of the sample, and cannot combine vertical sampling and horizontal sampling; [0005] 3) With traditional samplers, it is difficult to clean the sample, ...

AI Technical Summary

Problems solved by technology

[0003] 1) When the traditional sampler takes out the sample, it needs to lift the sampler, which is laborious to operate, and at the same time, it is easy to disturb the lower layer of the sample and affect the accuracy of the measurement data;

[0004] 2) The traditional sampler can only sample vertically, without horizontal sampling, and cannot measure the data of the three-dimensional space state of the sample, and cannot combine vertical sampling and horizontal sampling;

[0005] 3) With traditional samplers, it is difficult to clean the sample, and the residue of the previous sample may be carried into the next sample;

[0006] 4) Traditional samplers can only take samples and produce samples, but cannot obtain real-time humidity and compaction of samples
