Description

Technical Field

[0001] The present invention relates to the technical field of soil sampling equipment for environmental protection, and more specifically, to a soil detection sampling device for environmental protection. Background Art

[0002] Soil sampling device refers to the tool used to obtain soil samples. Traditional ones include soil drill, spade and shovel. The soil drill consists of a drill bit and a handle made of hard material (steel or hard plastic). The drill bit is usually spiral or cylindrical. The top of the spiral drill bit is a pair of sharp blades that can be rotated to cut into the soil. Immediately after the blade is an expanded soil cavity, the handle rotates downward to drill into the soil surface, and the soil sample of the soil layer to be collected can be 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, ensuring that the soil that has entered the cylinder when the soil drill is taking soil will not be scattered due to the movement of the soil drill. The handle of the soil drill is engraved with scales to control the sampling depth. After the soil drill is lifted out of the soil surface, the soil sample can be taken out from it, and soil samples of different depths can continue to be collected in the original sampling hole, but care should be taken to prevent soil debris around the sampling hole from flowing into the soil sampling hole when the soil drill is pulled out from the soil.

[0003] In the process of environmental protection, it is often necessary to sample and test the soil in the protected area. The document with the prior art publication number CN212988865U provides a soil detection sampling device for environmental protection. The device is provided with a sleeve that moves along the length direction of the hand-held rod. One side opening of the sleeve is located outside the hand-held rod. The sleeve is used to take soil and also includes an adjustment mechanism. The adjustment mechanism is used to adjust the extension length of the sleeve. Although the device has many beneficial effects, the following problems still exist: usually, multi-point sampling is required for sampling of the area. The device uses a hand-held rod and pushes out the sampling tube for sampling. Each manual sampling is cumbersome, and only one sampling can be performed on one point at a time. After each sampling, it needs to be collected separately. Not only is the sampling efficiency low, but it is also troublesome. The document with the prior art publication number CN213239542U has the same problem. In addition, the existing patent technology CN213397702U discloses a soil sampling device for soil remediation, which is provided with a first motor and a second motor to and a third motor, wherein the first motor realizes the forward and backward in and out movement of the sampling action through the first threaded rod, and the second motor is connected to the second threaded rod to adjust the height of the sampling bucket. Although the above structure can realize the forward and backward position adjustment movement and lifting sampling in soil sampling, it is necessary to set up multiple drive structures, resulting in a large volume and weight of the entire equipment and a high cost. In addition, a long screw structure needs to be set up to transmit motion through a simple threaded screw, which makes the length of the entire device longer, which is not conducive to comprehensive space utilization. In view of this, we propose a soil detection sampling device for environmental protection. Summary of the invention

[0031] The lifting transmission structure includes an L-shaped block 7 and a control rod 307. The L-shaped block 7 is provided on the front side of the L-shaped rod 6. The left rear end of the fixed plate 301 is rotatably connected to the control rod 307 through a pin shaft. The middle part of the inner side of the control rod 307 is rotatably connected to a pulley C308 through a pin shaft.

[0032] When the present application is working, it only needs to push the movable seat 1 to the required position. At this time, the square block 303 is rotated so that the L-shaped block 7 can be lowered and inserted into the soil to take samples at two points, and then it is retracted into the collecting box 3 for sampling, so that two samples can be taken at a time in the same area for later comparison, avoiding the existence of special circumstances, and then it can be pushed to take samples in the next area, avoiding the tedious and inefficient continuous sampling through the handheld rod sampling tube, and the device picks up two samples at one point at a time, avoiding the situation where they need to be collected separately each time, which not only improves the sampling efficiency but also is very convenient.
