Contaminated soil sampling and grinding device

Abstract

A contaminated soil sampling and grinding device comprises a machine table, a sampling mechanism, a lifting mechanism and a grinding and drying mechanism, the sampling mechanism, the lifting mechanism and the grinding and drying mechanism are arranged on the machine table, and the machine table comprises an upper table plate and a lower table plate which are horizontally arranged at intervals. The sampling mechanism comprises a supporting frame and a collecting cylinder arranged in the supporting frame, and the top of the collecting cylinder is sequentially connected with a lifting plate, a sampling motor, a screw and a first hand wheel. The supporting frame comprises a fixing plate and supporting legs. The lifting plate is movably installed on the inner sides of the supporting legs, and reset tension springs are connected to the four corners of the fixing plate and the four corners of the lifting plate. The top end of the spiral feeder is connected with a sampling motor, and the bottom end of the spiral feeder is connected with a drill bit. The grinding and drying mechanism comprises a grinding box, a drying box and a collecting hopper which are arranged in sequence; a grinding roller is arranged in an inner cavity of the grinding box and is driven by a grinding motor; and a dryer is arranged in the drying box. The device integrates the soil sampling mechanism, the soil grinding mechanism and the soil drying mechanism, and the soil pollution detection efficiency can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of soil detection, in particular to a device for sampling and grinding polluted soil. Background technique [0002] In recent years, with the improvement of the modernization of industrial and agricultural production, the problem of soil pollution has become increasingly serious, and countries around the world have carried out experimental demonstrations and technological research related to soil remediation. Before the soil remediation experiment, it is necessary to sample and test the soil. At present, the methods usually used are manual sampling, manual grinding, and manual drying pretreatment. When the sampling volume is large, the workload of sampling, grinding and drying will be greatly increased. The soil detection cycle is prolonged, which affects the detection efficiency. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings and deficiencies in th...
