Description

Technical Field

[0001] The utility model relates to the technical field of soil detection tools, in particular to a soil sampling drill for soil detection. Background Art

[0002] A soil drill is a soil sampling tool used to extract the original soil of the lower test soil as a sample to understand its properties. It is currently widely used in engineering geological exploration and survey work; however, most of the existing soil drills need to disassemble the drill bit after the soil is taken, and then use soil stripping tools to separate the soil from the inside of the drill bit. This not only makes the soil extraction process cumbersome, but also makes the soil extraction speed slow, resulting in low soil extraction efficiency. At the same time, due to the high humidity of the underground soil, in the process of separating the soil inside the drill bit, the soil is easy to adhere to the inner wall of the drill bit and is difficult to clean. This will cause the residual soil to be mixed in the subsequent extracted soil, which is easy to affect the subsequent soil detection results.

[0003] The existing Chinese patent with the announcement number CN208953316U discloses a soil drilling drill for soil detection, including a drill bit, a blade is arranged on the front of the drill bit, and a soil extraction groove is opened in the middle of the front of the drill bit, a connecting pipe is threadedly sleeved at one end of the drill bit, and a push rod is movably sleeved inside the drill bit, a push plate is fixedly connected to one end of the push rod, and a roller brush is fixedly sleeved on the outside of one end of the push rod.

[0004] In view of the above and existing related technologies, the inventors believe that the following defects often exist: the device drills holes by manually rotating the pressure rod, which is time-consuming and labor-intensive when used on relatively hard ground, and the use effect is not good, and needs to be improved; therefore, a soil drilling drill for soil testing is proposed to address the above problems. Utility Model Content

[0009] Preferably, a sampling block is threadedly connected to the surface of the lead screw, and both ends of the sampling block are slidably installed inside the sampling barrel. When it is necessary to take out the soil sample inside the sampling barrel, the control module controls the operation of driver 2, and driver 2 drives the lead screw to rotate, so that the sampling block slides downward, and then the soil sample inside the sampling barrel is quickly squeezed and separated. This is simple and convenient, and the efficiency of soil sampling is improved. When drilling, the sampling block moves to the bottom to prevent the sample from continuously entering the sampling barrel. When the sampling depth is reached, the sampling block moves upward, so that the soil sample at this location enters the sampling barrel, thereby realizing the sampling of soil samples at a specific depth.
