Soil detecting and sampling device for environmental protection

Abstract

The invention discloses a soil detecting and sampling device for environmental protection, and belongs to the technical field of soil sampling equipment for environmental protection. The soil detecting and sampling device for environmental protection comprises a moving base; a motor output shaft penetrates through the outer wall of a box body, extends into the box body and is sleeved with a square block; through cooperation of structures, the moving base only needs to be pushed to the needed position during working; at the moment, through rotation of the square block, an L-shaped block can descend and be inserted into soil for two-point sampling, then the sample is collected into the collecting box for sample placing, so that two samples can be taken at one time at one point of the barrel for comparison, and special conditions are avoided; then the barrel is pushed for sampling of a next area, and the conditions of complexity and low efficiency of continuous sampling through a handheld rod sampling barrel are avoided; and the device picks up two samples at one point at a time, so that the situation that the samples need to be independently collected again each time is avoided, the sampling efficiency is improved, and the device is very convenient to use.

Description

technical field [0001] The invention relates to the technical field of soil sampling equipment for environmental protection, in particular to a soil detection and sampling device for environmental protection. Background technique [0002] Soil sampling device refers to a tool used to obtain soil samples. The traditional ones are augers, shovels and shovels. Earth drills consist of a bit and handle made of a hard material (steel or hard plastic). The drill bit is usually helical or cylindrical. The top of the helical drill bit is a pair of sharp blades that can be rotated and cut into the soil. Then there is an enlarged cavity for holding soil on the blade. The soil sample collected from the soil layer is introduced into the cavity; the diameter of the cylindrical soil drill is slightly different at both ends, and the end connected to the handle is slightly larger than the end in contact with the soil, so as to ensure that the soil that has entered the cylinder is not Will...

Problems solved by technology

Although this device has more beneficial effects, there are still the following problems: usually, multi-point sampling is required for regional sampling. Can carry out one time sampling, also need to collect separately after going to finish each time, not only sampling efficiency is low, and more troublesome, and prior art publication number is that the document of CN213239542U has the same problem, discloses a A soil sampling device for soil remediation, which is provided with a first motor, a second motor and a third motor, wherein the first motor realizes the forward and backward movement of the sampling action through the first threaded rod, and the second motor is connected with the second threaded rod, Realize the adjustment of the height of the sampling barrel. Although the above structure can realize the front and rear position adjustment movement and lifting sampling in soil sampling, it needs to set up multiple driving structures, resulting in large volume and weight of the whole equipment, and high cost. In addition, through simple The transmission movement of the threaded screw requires a longer screw structure, which makes the length of the whole device longer, which is not conducive to comprehensive space utilization. In view of this, we propose a soil testing and sampling device for environmental protection
