[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0020] See also Figures 1 to 3The utility model provides a technical solution: a rock and soil sampler, including a bracket 1, the shape of the bracket 1 is "U", and movable plates 3 are arranged on both sides of the bracket 1 through a storage mechanism. The storage mechanism includes a storage groove 2, and protrusions 8 are arranged in an array on the outer wall of the movable plate 3. A sampling barrel 4 is arranged on the inner side of the bracket 1 through a screw 5, and the screw 5 is movably arranged at the center position of the top of the sampling barrel 4 through a rotating shaft. A material-taking mechanism is arranged on the inner side of the bracket 1, and the material-taking mechanism includes two fixed rods 10 and a fixed plate 9. The two fixed rods 10 are symmetrically fixed on the top of the fixed plate 9. The sampling barrel 4 can be positioned by the bracket 1 and the movable plate 3 to improve the stability of the sampling barrel 4.

[0021] In this embodiment, the fixing plate 9 is disc-shaped, and the fixing plate 9 is arranged inside the sampling barrel 4. The two fixing rods 10 are slidably installed inside the sampling barrel 4 through sliding holes. The two fixing rods 10 are symmetrically fixed on the top wall on the inner side of the bracket 1. The front end of the sampling barrel 4 is provided with a through groove, and the bottom end of the sampling barrel 4 is provided with a blade. The screw rod 5 is screwed and installed at the inner center position of the top end of the bracket 1 through a screw hole. A handle 6 is fixed on the top end of the screw rod 5. The screw rod 5 is driven by the handle 6, and the screw rod 5 drives the sampling barrel 4 to rise. Under the action of the fixing plate 9 and the fixing rod 10, the soil inside the sampling barrel 4 is taken out. The operation is simple and easy to use.

[0022] In this embodiment, air holes 7 are provided on both sides of the top of the bracket 1 and both sides of the top of the sampling tube 4 to discharge the air inside the sampling tube 4 and facilitate soil to enter the interior of the sampling tube 4.

[0023] In this embodiment, the receiving grooves 2 are symmetrically opened inside the two ends of the bracket 1, and the bottom end of the movable plate 3 is movably installed inside the receiving groove 2 through a torsion spring shaft. Under the torsion force of the torsion spring shaft, the movable plate 3 can be stored in the receiving groove 2, thereby conveniently reducing the volume of the rock and soil sampler.

[0024] When using the soil sampler, the movable plate 3 is unscrewed from the inside of the storage groove 2, and the bottom end of the movable plate 3 twists the torsion spring shaft so that the torsion spring shaft accumulates force, and the movable plate 3 is fitted with the soil surface. The stability of the movable plate 3 is improved by the protrusion 8. The movable plate 3 is stepped on, and the handle 6 and the screw 5 are turned. The sampling tube 4 is driven down by the screw connection between the screw 5 and the bracket 1. The sampling tube 4 is inserted into the soil through the blade, and the soil enters the sampling tube 4. The air inside the sampling tube 4 is discharged through the through groove and the air hole 7. The sampling tube 4 can be positioned by the bracket 1 and the movable plate 3, and the stability of the sampling tube 4 is improved to prevent the sampling tube 4 from tilting. Since the bracket 1 and the movable plate 3 are fixed, The rock and soil sampler can sample soils of different hardnesses. After sampling, the handle 6 and the screw 5 are rotated in the opposite direction, and the screw 5 drives the sampling tube 4 to rise. Since the bracket 1 is fixed, the fixing plate 9 and the fixing rod 10 are fixed. As the sampling tube 4 rises, the soil is discharged from the soil inside the sampling tube 4 under the squeezing of the fixing plate 9. The operation is simple and easy to use. After use, the movable plate 3 is loosened, and the movable plate 3 rotates toward the inside of the receiving groove 2 under the torsion of the torsion spring shaft, and the movable plate 3 is received by the receiving groove 2. At the same time, the sampling tube 4 is adjusted to the inner side of the bracket 1, which can improve the safety of the rock and soil sampler and prevent the blade at the bottom of the sampling tube 4 from causing harm to the user.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
