AI Technical Summary
Existing soil samplers are prone to touch the side wall of the sampling hole when moving in or out of the sampling hole, causing soil debris to flow into the sampling hole, affecting the purity of the sampling.
A soil sampling device is designed, including a sleeve and a sampling mechanism. The sleeve can separate the sampling mechanism from the inner wall of the soil. The sampling mechanism includes a sampling cylinder, an inner rod and a baffle. The position of the baffle is adjusted by the moving mechanism to avoid scraping the soil on the side wall of the sampling hole during sampling.
The soil on the side walls of the sampling hole is separated by the sleeve to ensure that the impurity soil in the first sampling can be discarded. During the subsequent sampling process, the sampling mechanism moves within the sleeve to avoid scraping the side wall soil and improve the purity of the soil sampling.

[0002] A soil sampler refers to a tool used to obtain soil samples. Commonly used ones include soil drills, spades and shovels. Existing soil samplers are generally composed of a sampling tube and a handle made of hard materials. When taking soil, a drill is first used to drill a hole in the soil, and then the sampler is transported to the sampling hole to sample the soil. However, when the sampler is moved in or out of the sampling hole, it is easy to touch the side wall of the sampling hole, causing soil debris to flow into the soil hole, affecting the sampling. For this reason, a soil sampling device is proposed. Utility Model Content

[0016] The following is combined with Figure 1-3 This application is described in further detail.
[0017] The embodiment of the present application discloses a soil sampling device, including a sleeve 1 and a sampling mechanism. The sampling mechanism can be moved out of or into the sleeve 1. The sleeve 1 can separate the sampling mechanism from the inner wall of the soil. The sampling mechanism includes a sampling barrel 13, an inner rod 11 and a baffle 14. One end of the inner rod 11 is inserted into the sampling barrel 13 and connected to the baffle 14. The baffle 14 is arranged inside the sampling barrel 13. A moving mechanism is arranged at the upper end of the sampling barrel 13, which can drive the baffle 14 to move in the sampling barrel 13.
[0018] During actual use, the ground is first drilled with a drill. In this embodiment, a sleeve 1 is provided on the outer surface of the sampling mechanism to separate the soil on the side wall of the sampling hole from the sampling mechanism. In the process of multiple sampling, the sleeve 1 and the sampling mechanism are first inserted into the sampling hole, and the sampling mechanism is used for the first sampling. In order to ensure the purity of the sample, the first sample contains more soil from the side wall of the sampling hole, which can be discarded, and the sampling mechanism is used for subsequent sampling. In the subsequent sampling process, the sampling mechanism moves in the sleeve 1 and will not scrape off the soil on the side wall of the sampling hole, thereby ensuring the purity of the soil sampling.
[0019] Furthermore, the moving mechanism includes a sliding sleeve 12 sleeved on the inner rod 11 , one end of the sliding sleeve 12 is fixedly connected to the sampling tube 13 , a fixing bolt 10 is inserted into the sliding sleeve 12 , and the fixing bolt 10 abuts against the surface of the inner rod 11 .
[0020] Furthermore, a slide seat 5 is fixedly connected to the upper end of the inner rod 11, and plug blocks 7 are slidably connected to both sides of the slide seat 5. Slots 6 adapted to the plug blocks 7 are opened on both sides of the upper surface of the sleeve 1, and the plug blocks 7 can be moved into or out of the slots 6.
[0021] In this embodiment, by providing a moving mechanism, the position of the baffle 14 in the sampling barrel 13 can be adjusted. When the device is idle, the sleeve 12 and the sampling barrel 13 can be moved so that the baffle 14 is located at the opening of the sampling barrel 13, and the positions of the sleeve 12 and the sampling barrel 13 are fixed by the fixing bolts 10 to prevent contamination of the inner wall of the sampling barrel 13. When sampling, the fixing bolts 10 are loosened, and then the sleeve 12 and the sampling barrel 13 are moved so that the baffle 14 is located in the sampling barrel 13 to ensure that the sampling barrel 13 can sample normally.
[0022] Furthermore, a guide rod 8 is fixedly connected to the slide seat 5, the guide rod 8 passes through the plug block 7, and a spring 9 is sleeved on the surface of the guide rod 8. When the two groups of plug blocks 7 are close to each other, the spring 9 is stretched or compressed.
[0023] In this embodiment, by setting the plug block 7 to cooperate with the slot 6, the connection or separation of the sleeve 1 and the sampling mechanism can be controlled by moving the plug block 7. When the sleeve 1 is connected to the sampling mechanism, it is convenient to carry the entire device. When the sleeve 1 is separated from the sampling mechanism, it is convenient for the sampling mechanism to perform sampling work.
[0024] Furthermore, a plurality of groups of ear plates 2 are fixedly connected to the outer surface of the top of the sleeve 1 , positioning rods 3 are inserted on the ear plates 2 , and hammer blocks 4 are fixedly connected to the upper ends of the positioning rods 3 .
[0025] In this embodiment, the positioning rod 3 is inserted into the soil, which can ensure the stability of the sleeve 1 and ensure that the sleeve 1 is stably installed inside the sampling hole.
