Description

Technical Field

[0001] This utility model relates to the field of sampling device technology, specifically to an automatic soil sampling device. Background Technology

[0002] During construction, backfill soil needs to be sampled for testing. This is typically done manually using a ring cutter. First, surface soil and gravel are removed at the sampling point using a shovel or other tools. Then, the ring cutter is placed vertically downwards, supported by a ring cutter holder, and the holder is hammered to fully insert the ring cutter into the backfill soil. The surrounding soil is then cleared to remove the ring cutter, completing the sampling process. This process has the following problems: it is manual and cumbersome; the ring cutter is difficult to stabilize when hammered, affecting the testing results; and especially on sloping ground, it is difficult to control the ring cutter's vertical and horizontal insertion, further impacting the testing results. Although auxiliary devices exist to vertically press the ring cutter into the ground, these often seal the top surface or leave ventilation holes. These features can create air pressure inside the ring cutter during sampling, hindering the complete and smooth insertion of the soil sample.

[0003] Therefore, how to solve the above-mentioned technical problems has become the subject of this utility model. Utility Model Content

[0004] The purpose of this invention is to solve the problems mentioned in the background art and to propose an automatic soil sampling device that is easy to operate and can effectively improve the efficiency of backfill soil sampling and enhance the accuracy of soil sample testing.

[0007] The cleaning component includes a rotating cylinder vertically rotatably connected to one side of the top of the mounting plate. The bottom of the rotating cylinder is open and a sliding rod extending to the bottom of the mounting plate is vertically slidably connected to its inner side. A cleaning plate is fixedly connected to the bottom end of the sliding rod, and a number of cleaning brushes are evenly arranged on the bottom surface of the cleaning plate.

[0008] A through thread is provided at the center of the top of the rotating drum, and the thread is connected to the threaded connection.

[0009] A first threaded rod is connected through its upper and lower sides. The bottom end of the first threaded rod is rotatably connected to the top end of the sliding rod. A rotating handle is fixedly connected to the top end of the first threaded rod. A spring is sleeved on the outer part of the first threaded rod located on the rotating cylinder.

[0010] A first gear is coaxially sleeved on the lower side of the rotating drum. The first gear meshes with a second gear rotatably connected to the top of the mounting plate. The second gear is coaxially fixedly connected to the output end of the motor. The motor is mounted on a fixed frame, and the fixed frame is fixedly connected to the mounting plate.

[0011] The soil sampling component includes a mounting plate that slides vertically and extends through its upper and lower sides.

[0012] The sliding column has a pair of ear plates symmetrically arranged on both sides. The bottom of each ear plate is fixedly connected to the telescopic end of an electric telescopic rod. The bottom fixed end of the electric telescopic rod is fixedly connected to the top of the mounting plate.
