Detachable sampling device for soil detection

Abstract

The invention discloses a detachable sampling device for soil detection. The detachable sampling device comprises an upper connecting tank, a lower connecting ring column, a sampling mechanism, a rotary driving mechanism, an outer side connecting ring, an inner side connecting ring and connecting screw rods; the outer connecting ring is installed on the outer side of the periphery of the lower endof an upper feeding cover body, the inner connecting ring is installed on the inner side of the periphery of the upper end of a lower containing cover body, and the lower containing cover body is inserted into the inner side of the outer connecting ring connected with the outer side of the periphery of the lower end of the upper feeding cover body through the inner connecting ring on the inner side of the periphery of the upper end; and movable positioning is conducted through a plurality of connecting screw rods, so that movable connection of the upper feeding cover body and the lower containing cover body is achieved, the detachability is high, and discharging and cleaning are very convenient.

Description

technical field [0001] The invention relates to a detachable sampling device for soil detection. Background technique [0002] At present, heavy metals are the main inorganic pollutants in soil. Since heavy metals cannot be decomposed by soil microorganisms, heavy metals continue to accumulate and transform into more toxic methyl compounds. Some heavy metals even accumulate in the human body through the food chain. , seriously endangering human health; in some muddy areas, such as ponds or rivers, heavy metals in the soil may enter the human body through fish, shrimp, rice, etc., because the soil will become fluid soil or even silt when it meets water, sampling personnel It is difficult to sample the deep soil, and when the sampling device is inserted into the soil and the sampling device is pulled out, the sampled soil is easy to flow out of the sampling device, making sampling difficult, time-consuming and laborious. The resistance of the sampling cover is relatively larg...

[0002] At present, heavy metals are the main inorganic pollutants in soil. Since heavy metals cannot be decomposed by soil microorganisms, heavy metals continue to accumulate and transform into more toxic methyl compounds. Some heavy metals even accumulate in the human body through the food chain. , seriously endangering human health; in some muddy areas, such as ponds or rivers, heavy metals in the soil may enter the human body through fish, shrimp, rice, etc., because the soil will become fluid soil or even silt when it meets water, sampling personnel It is difficult to sample the deep soil, and when the sampling device is inserted into the soil and the sampling device is pulled out, the sampled soil is easy to flow out of the sampling device, making sampling difficult, time-consuming and laborious. The resistance of the sampling cover is relatively large when it enters, and it is inconvenient to use. At the same time, it is necessary to improve the convenience of disassembly, replacement and cleaning of the sampling cover.
