A foot-operated soil sampling device

Abstract

The invention discloses a pedal type soil sampling device. The pedal type soil sampling device comprises a fixed sleeve, a first threaded rod, a pedaling mechanism, a sampling tube and a material blocking mechanism. The sampling tube is arranged in the inner side of the fixed sleeve. The upper end of the sampling tube is fixedly connected to the first threaded rod. The first threaded rod passes through the upper end of the fixed sleeve and is connected to a threaded sleeve fixed to the upper end of the fixed sleeve through threads. The threaded sleeve is rotatingly connected to the fixed sleeve. The material blocking mechanism is arranged in the inner side of the sampling tube. A bottom plate in the right side is provided with the pedaling mechanism. The pedaling mechanism comprises limiting side plates, a foot pedal, a curved plate, a ring gear, a ratchet mechanism, a lantern ring, the bottom plate and a rotating shaft. The pedal type soil sampling device has a novel design. Through the pedaling mechanism, sampling is realized without electric energy as power so that energy is saved and the difficulty of manual rod insertion is reduced.

Description

technical field [0001] The invention relates to a sampling device, in particular to a foot-operated soil sampling device. Background technique [0002] With people's increasing awareness of environmental protection, soil remediation is the top priority of the current environmental protection task. In the early stage of soil remediation, environmental protection evaluation units need to evaluate the pollution degree of the soil to be remediated, and then the remediation work cannot be avoided. Pre-sampling work, for this type of sampling structure, most of the current samplers can only sample the surface or shallow layers, but for deep or specified depth sampling, many testing units use special equipment for sampling. The area and purchase cost are too high, which requires a lot of manpower and material resources. Of course, the removal of soil samples also faces the problem of efficiency. Some small devices have also been born, but it is always impossible to obtain soil samp...

[0002] With people's increasing awareness of environmental protection, soil remediation is the top priority of the current environmental protection task. In the early stage of soil remediation, environmental protection evaluation units need to evaluate the pollution degree of the soil to be remediated, and then the remediation work cannot be avoided. Pre-sampling work, for this type of sampling structure, most of the current samplers can only sample the surface or shallow layers, but for deep or specified depth sampling, many testing units use special equipment for sampling. The area and purchase cost are too high, which requires a lot of manpower and material resources. Of course, the removal of soil samples also faces the problem of efficiency. Some small devices have also been born, but it is always impossible to obtain soil samples when taking soil. Can also guarantee higher unearthed rate simultaneously, and then work efficiency is low, can't satisfy current demand, there are many defects in summing up present earth-borrowing device
