DETAILED DESCRIPTION

[0019] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0020] like Figure 1-4 As shown, a soil detection sampling device of the utility model comprises a base 1, four symmetrically distributed support rods 10 are fixedly provided on the upper side of the base 1, an operating platform 11 is fixedly provided on the upper side of the four support rods 10, a T-shaped slot 12 is provided on the operating platform 11, a T-shaped block 13 matching the T-shaped slot 12 is slidably mounted on the upper side of the operating platform 11, a circular cavity is provided inside the T-shaped block 13, a through slot is provided on the T-shaped block 13, a cylinder 14 matching the through slot is rotatably mounted on the T-shaped block 13, a circular ring 15 matching the circular cavity is fixedly provided on the side wall of the cylinder 14, a threaded section is processed inside the cylinder 14, a first screw 16 matching the threaded section is rotatably mounted on the upper side of the operating platform 11, a barrel 17 is fixedly provided on the lower side of the first screw 16, a circular hole 18 matching the barrel 17 is provided on the base 1, a plurality of circumferentially distributed convex teeth 19 are fixedly provided on the lower side wall of the barrel 17, and a plurality of circumferentially distributed oblique openings 20 are provided on the upper side of the barrel 17;

[0021] When the utility model is used, the user directly rotates the cylinder 14, and the ring 15 on the side wall of the cylinder 14 makes the cylinder 14 always rotate in the middle of the T-block 13. The threaded section on the inner wall of the cylinder 14 is threadedly connected with the first screw 16. The rotation of the cylinder 14 drives the first screw 16 to descend, and the first screw 16 drives the barrel 17 to descend. Driven by the first screw 16, the barrel 17 moves downward from the circular hole 18 on the upper side of the base 1. After the convex teeth 19 on the lower side of the barrel 17 come into contact with the soil, the cylinder 14 is continuously rotated, and the first screw 16 continues to rotate to drive the barrel 17 to descend, so that the convex teeth 19 separate the soil along the inside and outside of the barrel 17, so that the barrel 17 penetrates into the soil. After the barrel 17 is completely immersed in the soil, the soil on the upper side of the barrel 17 is discharged from the inside of the barrel 17 from the oblique mouth 20 on the upper side of the barrel 17, so that the barrel 17 can penetrate into the soil and sample soil at different depths.

[0022] The utility model rotates the cylinder so that the first screw drives the cylinder to descend. When the cylinder contacts the soil, the convex teeth on the lower side of the cylinder separate the soil so that the cylinder goes deep into the soil. The soil on the upper side of the cylinder is discharged from the cylinder through the oblique mouth. The soil at different depths can be sampled. The operation is simple and the use is convenient.

[0023] The first screw 16 is provided with a square groove, the lower side of which is connected to the inside of the barrel 17, a square rod 21 matching the square groove is slidably mounted inside the first screw 16, a push plate 22 is fixedly provided at the lower side of the square rod 21, a groove matching the push plate 22 is provided at the upper side of the barrel 17, a pressing plate 23 is fixedly provided at the upper side of the square rod 21, and a spring 24 is fixedly provided between the lower side of the pressing plate 23 and the upper side of the first screw 16;

[0024] When the utility model is not in use, under the elastic action of the spring 24, the pressing plate 23 is pushed away from the upper side of the first screw rod 16, and the pressing plate 23 makes the push plate 22 always abut against the upper side wall of the cylinder 17 through the square rod 21, so as to avoid the push plate 22 blocking the oblique opening 20, thereby ensuring the smooth operation of the device;

[0025] During the use of the utility model, after the soil sampling is completed, the user rotates the cylinder 14 to take out the barrel 17, and then slides the T-block 13 to drive the barrel 17 to move. After the lower side of the barrel 17 is aligned with the sample storage bottle, the user presses the pressing plate 23 downward, and the pressing plate 23 compresses the spring 24, and the pressing plate 23 pushes the square rod 21 downward, and the square rod 21 drives the push plate 22 to move downward inside the barrel 17, pushing out the soil inside the barrel 17, so as to facilitate the removal of the sample inside the barrel 17, thereby improving the sampling efficiency and facilitating the use.

[0026] Two threaded holes are arranged on the upper side of the base 1 and are symmetrically distributed. Two second screws 25 matching the threaded holes are rotatably mounted on the upper side of the base 1. The lower sides of the two second screws 25 are processed into a cone shape. Before sampling the soil, the user first rotates the second screw 25 so that the lower side of the second screw 25 is inserted into the soil, so as to make the device more stable and ensure the smooth operation of the device.

[0027] A rotating block 26 is fixedly provided on the upper side of the two second screw rods 25, and a slot matching the rotating block 26 is opened on the lower side of the push plate 22; when using the utility model, the user first slides the T-block 13, and then rotates the cylinder 14 to lower the barrel 17, so that the upper side of the second screw rod 25 extends into the interior of the barrel 17, and then continues to rotate the cylinder 14 to make the slot on the lower side of the push plate 22 cooperate with the rotating block 26 on the upper side of the second screw rod 25. The user then rotates the cylinder 14, and the cylinder 14 drives the second screw rod 25 to rotate synchronously through the slot on the lower side of the push plate 22, so that the second screw rod 25 extends into the soil to provide support for the device. During the entire sampling process, the user only needs to rotate the cylinder 14 for easy operation.

[0028] Two placement seats 30 symmetrically distributed on the left and right are fixedly provided on the upper side of the base 1 to place and limit the sample storage bottles, thereby reducing the load on the user.

[0029] A hand wheel 31 is fixedly provided on the upper side of the cylinder 14 , so that the user can rotate the cylinder 14 conveniently.

[0030] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the relevant technical field without departing from the spirit and technical ideas disclosed in the present invention shall still be covered by the claims of the present invention.
