Problems solved by technology

[0003] With reference to the publication number: shown in CN108801689B, this invention adopts mechanical equipment to replace manual soil sampling. Because the soil hardness in various areas within the nuclear radiation range is different, individual areas may be sandy and gravel areas, so conventional mechanical collection equipment is very difficult. Difficult to meet various hard soil layers within the range of nuclear radiation
[0004] Referring to the publication number: CN111811877B, this invention is aimed at collecting equipment for deep soil. Since the water content in the geology of each region is different, when the deep soil with a large water content is collected into the equipment, the metal soil guide inside the equipment will Corrosion will be caused during long-term use, which will pollute other soil samples, and the amount of soil radiation in each area within the nuclear radiation direction is different. Using the above equipment will cause cross-contamination of soil with different content in each area, which is not conducive to the collection of samples.
[0005] According to the hazards of nuclear radiation, various sharp substances contained in the soil can easily cause damage to the protective clothing such as the operator's gloves. In order to reduce the artificial collection of soil in the nuclear radiation area, how to adapt to different geological conditions in the nuclear radiation area Digging is the technical difficulty that the inventor needs to solve

Abstract

The invention discloses sample collection equipment for nuclear radiation soil detection and evaluation. The equipment comprises a support mechanism, an earth surface leveling assembly, a driving mechanism, a soil sampling mechanism, a sample storage mechanism and a hard soil layer ditching mechanism, wherein the support mechanism comprises a main frame for determining the sample extraction specification area and a horizontal transverse movement combination, and the earth surface leveling assembly comprises a load bearing plate installed on the inner side of the main frame. According to the invention, a rotating shaft is controlled to enable a driving shaft and a fixing piece to integrally lift along a sliding groove in the inner side of a vertical sliding groove while a motor is started and controlled to operate to drive a first transverse shaft and the driving shaft, a rotating disc at the bottom end of the driving shaft is meshed with a toothed disc at the outer end of an inner core, and a cutting sheet and a soil returning piece are driven to turn over and cut downwards along nuclear radiation soil, so that when an operator treats the soil in the nuclear radiation range, the situation that sharp substances in the soil damage gloves or protective clothing of the operator is reduced, and complete dissection of the soil in a sample area is greatly preserved.

Description

technical field [0001] The invention relates to the field of soil sample collection, in particular to sample collection equipment for nuclear radiation soil detection and evaluation. Background technique [0002] Nuclear radiation is a kind of nuclear pollution. Nuclear pollution mainly refers to the damage to the environment caused by the remnants of nuclear material leakage. The radiation and atomic dust generated by the remnants of nuclear material will directly cause irreversible damage to the soil. Among them The remnants of nuclear substances will also produce secondary pollution with the passage of time, causing pollution of groundwater sources and so on. [0003] With reference to the publication number: shown in CN108801689B, this invention adopts mechanical equipment to replace manual soil sampling. Because the soil hardness in various areas within the nuclear radiation range is different, individual areas may be sandy and gravel areas, so conventional mechanical c...
