Environment-friendly soil collection device capable of being ejected out automatically according to drilling depth

Abstract

The invention belongs to the technical field of soil remediation and discloses an environment-friendly soil collection device capable of being ejected out automatically according to drilling depth. The collection device comprises an outer collection sleeve; an inner drill rod is slidably connected to the inner side wall of the outer collection sleeve; a drill bit is fixedly connected to the bottomof the inner drill rod; a detection chamber is fixedly connected to the bottom of the outer collection sleeve; a rotating head is movably connected to the interior of the detection chamber; a rotating rod is fixedly connected to the top end of the rotating head; chucks do not limit buckles any more, so that extension springs on the buckles drive a pull plate to eject the inner drill rod out, thedevice can be automatically ejected out after collecting soil the preset depth, so that the soil collecting precision is improved; a mechanical mechanism is utilized, extra electric equipment does notneed to be adopted for detecting the drilling depth, the purposes of energy conservation and environmental protection are achieved; in addition, the gear ratio between gear sets can be adjusted according to specific requirements, so that the automatic ejection depth can be adjusted, and therefore, the application range of the device can be widened.

Description

technical field [0001] The invention relates to the technical field of soil remediation, in particular to a soil collection device for environmental protection that can be automatically ejected according to the depth of a borehole. Background technique [0002] Soil remediation is a technical measure to restore contaminated soil to normal functions. In the process of soil remediation, the soil to be remediated needs to be sampled and tested. In the prior art, during the process of soil collection, a drill pipe is usually used to drill into the soil Internally, sampling is carried out. After the existing drill pipe is inserted into the soil, it cannot be accurately collected according to the specific collection depth, so that the soil collection depth is too much or too little, resulting in the need for re-collection or low collection accuracy. At the same time, the current Most of the devices usually require additional sensors and other electrical equipment to sense the coll...
