[0002] Soil sampling is an important component of geotechnical engineering monitoring. Through soil sampling, we can fully understand the soil conditions at the construction site, provide a scientific basis for project supervision, and ensure that project quality, safety, and environmental protection requirements are met. Currently, soil sampling devices are typically drill rods with sampling slots at the end. When the drill rod is inserted into the soil, some soil enters the sampling slots. When the drill rod is removed from the soil, this soil is carried out. However, existing sampling slots are usually open, making it easy for soil to fall out of the sampling slots during the drill rod's removal. Therefore, a sampler for engineering supervision is proposed. Utility Model Content

[0019] The following is combined with Figure 1-6 This application is described in further detail.
[0020] The embodiment of the present application discloses an engineering supervision sampler, including a sampling rod 1, a sampling groove 2 is provided at the bottom of the sampling rod 1, and the opening of the sampling groove 2 is inclined, and handles 6 are symmetrically fixedly connected to the two sides of the upper outer surface of the sampling rod 1, and an outer cylinder 4 is provided on the surface of the sampling rod 1 through a moving mechanism, and the outer cylinder 4 can move up and down along the outer surface of the sampling rod 1, and a groove body 11 is provided on the outer surface of the outer cylinder 4, and the groove body 11 opens downward, and a cover plate 3 is provided inside the groove body 11, and both sides of the top outer surface of the cover plate 3 are fixedly connected to a rotating shaft 12, and the rotating shaft 12 is rotatably installed inside the groove body 11, and the cover plate 3 and the opening edge of the sampling groove 2 are magnetic, and the cover plate 3 and the opening of the sampling groove 2 attract each other.
[0021] Furthermore, the tank body 11 and the cover plate 3 are arranged on one side of the opening of the sampling tank 2 , and the area of the cover plate 3 is larger than the area of the opening of the sampling tank 2 .
[0022] In this embodiment, when sampling, the user holds the handle 6, inserts the sampling rod 1 into the sampling location, and rotates the sampling rod 1 to separate the soil in the sampling groove 2 from other soil. The sampling rod 1 is then lifted a certain distance, and the outer cylinder 4 is driven downward along the sampling rod 1 by the moving mechanism. When the cover plate 3 is transferred to the sampling groove 2, the cover plate 3 is moved toward the opening of the sampling groove 2 by gravity, and the cover plate 3 is thus covered at the opening of the sampling groove 2. Therefore, the soil can be prevented from falling during the process of removing the sampling rod 1 from the soil.
[0023] Furthermore, the moving mechanism includes connecting rods 5 symmetrically fixedly mounted on both sides of the upper surface of the outer cylinder 4, and the surface of the handle 6 is provided with through holes 10 adapted to the connecting rods 5. The upper ends of the two groups of connecting rods 5 respectively pass through the two groups of through holes 10 and are fixedly connected with a sliding sleeve 9. The inner opening of the sliding sleeve 9 is adapted to the outer surface of the sampling rod 1, and the sliding sleeve 9 is slidably sleeved on the outer surface of the sampling rod 1.
[0024] Furthermore, a spring 7 is sleeved on the outer surface of the sleeve 9 , the upper end of the spring 7 is fixedly connected to the sleeve 9 , and the lower end of the spring 7 is fixedly connected to the handle 6 . In a natural state, the spring 7 causes the outer tube 4 to be located above the sampling slot 2 .
[0025] In this embodiment, in the initial state, the outer cylinder 4 is located on the upper surface of the sampling slot 2, and the cover plate 3 is kept vertically due to the movement interference of the outer wall of the sampling rod 1. When the sampling slot 2 needs to be blocked, the user manually presses the sliding sleeve 9 to drive the connecting rod 5, the outer cylinder 4 and the cover plate 3 to move downward. When the cover plate 3 moves to the opening of the sampling slot 2, the cover plate 3 is no longer blocked by the outer wall of the sampling rod 1. Instead, it is affected by the gravitational force at the opening of the sampling slot 2 and deflected to the side of the opening of the sampling slot 2, thereby achieving the purpose of blocking the sampling slot 2.
[0026] In this embodiment, after the sampling rod 1 is removed from the soil, the user manually lifts the sliding sleeve 9, driving the connecting rod 5, the outer cylinder 4 and the cover plate 3 to move upward, so that the connecting rod 5, the outer cylinder 4 and the cover plate 3 are reset, thereby restoring the sampling slot 2 to an open state.
[0027] Furthermore, a push plate 13 is movably installed inside the sampling groove 2, and the push plate 13 is adapted to the inner surface of the sampling groove 2, and a push rod 8 is fixedly connected to the surface of the push plate 13. A slide groove adapted to the push rod 8 is opened in the center of the sampling rod 1, and the upper end of the push rod 8 passes through the slide groove to the outside of the sampling rod 1.
[0028] In this embodiment, by setting the push plate 13 to match the push rod 8, when the soil viscosity is high and difficult to be taken out from the sampling trough 2, the user can manually push the push rod 8 to drive the push plate 13 to move, so that the push plate 13 can push the soil out of the sampling trough 2.
