Description

Technical Field

[0001] This utility model relates to the field of soil sampling technology, and in particular to a rapid sampling device for soil testing. Background Technology

[0002] Different soils contain different nutrients and are subject to different levels of pollution. Therefore, it is necessary to take soil samples and test them. However, existing soil testing sampling devices have disadvantages such as low sampling efficiency, inconvenience in moving, and complicated operation.

[0003] A patent with publication number CN106769188B discloses a rapid sampling device for soil testing. This patent includes a housing, a slide rail, a first bearing seat, a nut, a rotating rod, a large gear, a collection bucket, a stop block, a one-way feed pipe, a drill bit, a connecting rod, a second bearing seat, a lead screw, a rotating shaft, a small gear, a second slider, and wheels. The device is moved to the location where soil sampling is needed. Then, a first motor is started, which drives the rotating rod to rotate, thereby driving the large gear to rotate, which in turn drives the small gear to rotate, causing the rotating shaft to rotate. The rotating shaft then drives the lead screw to rotate, causing the nut to move downwards, which in turn moves the rotating rod downwards. The downward movement of the rotating rod moves the collection bucket downwards, which in turn moves the drill bit downwards. Simultaneously, the rotating rod rotates... The process involves rotating the collection bin, which in turn rotates the drill bit. The drill bit moves downwards while rotating, drilling a hole in the ground to sample the soil. When the drill bit reaches the required sampling depth, the first motor is shut off, stopping the drill. Then, the cylinder shortens, causing a stop block to move upwards. When the stop block can no longer block the one-way feed pipe, the cylinder stops shortening, and the first motor restarts in the same direction, causing the drill bit to rotate downwards a further distance. This allows the soil sample to fall through the one-way feed pipe into the bottom of the collection bin. The first motor then restarts in the opposite direction, causing the drill bit to move upwards and rotate in the opposite direction. Because of the one-way feed pipe, the soil will not fall into the bottom of the collection bin through it. When the drill bit reaches the ground, the first motor is shut off, and the drill bit is turned to empty the collected soil from the collection bin for testing. To resample the soil, the above steps are repeated. However, this patent has the following problems:

[0004] Existing soil sampling structures use only one sampling tube, which cannot sample soil at different depths. The sampling process is unstable, which leads to increased sampling time and low efficiency.

[0005] To address the above problems, a rapid sampling device for soil testing needs to be designed to overcome them. Utility Model Content
