Sampling device for geological mud flat environment detection

Abstract

The invention discloses a sampling device for geological mud flat environment detection and mainly relates to the field of geological environment devices. The sampling device comprises a barrel, a window plate, a drill bit and a sampling disc, wherein a sampling window is formed in the barrel and matched with the window plate for use, a vertical first rotating shaft and a guide rail sleeve are arranged in the barrel, a lifting sleeve in lifting connection with the guide rail sleeve is arranged on the guide rail sleeve, the sampling disc is detachably connected with the lifting sleeve, the first rotating shaft is electrically driven, the bottom end of the first rotating shaft is in transmission with a drill spindle of the drill bit through a gear, and the drill bit is arranged below the barrel. The sampling device has the beneficial effects that a reconnaissance worker can be assisted in obtaining samples at multiple depths simply and efficiently, purity of the obtained samples is improved substantially, a detection result is in accordance with a real condition, and accurate deposition data can be obtained.

Description

technical field [0001] The invention relates to the field of geological environment devices, in particular to a geological tidal flat environment detection and sampling device. Background technique [0002] Tidal flats are important geological environmental resources in my country, featuring large area, concentrated distribution, good location conditions, and great potential for comprehensive development of agriculture, animal husbandry and fishery. Tidal flats are not only an important land resource and space resource, but also contain various minerals, organisms and other marine resources. Protecting tidal flat resources in our country is the top priority of geological environment work. [0003] In recent years, with the continuous improvement of the scientific level, people's production and operation activities have more and more influence on the geological environment. For tidal flat resources, due to the development of various human-operated projects such as land recl...

Problems solved by technology

However, the existing sampling device is not only unable to dig out multiple groups of samples at any depth according to the needs after drilling, which brings difficulties to the sampling work

Moreover, in its top-down drilling sampling operation, the surface and shallow layers of ions are entrained to the bottom layer, so that the composition of the sample cannot truly reflect the soil deposition at the current depth

Therefore, the existing sampling device cannot meet the sampling requirements of the tidal flat sediment sample deposition inspection, the sampling operation is difficult, and the sample purity is poor
