[0023] The technical solutions in the embodiments of the present application will be described clearly and completely in the following with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, not all. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present application.

[0024] As Figures 1-4The utility model discloses an investigation soil collecting device, including the collection cylinder 1, be equipped with the storage cavity 101 in collection cylinder 1, the bottom of collection cylinder 1 is provided with the bottom disc 2 in the storage cavity 101, the bottom of bottom disc 2 is provided with the taper head 3, the bottom disc 2 is equipped with the counterbore 201 along the vertical direction, the taper head 3 is slidably arranged in the counterbore 201, the sidewall of counterbore 201 is equipped with the inclined hole 202 that communicates the storage cavity 101, the top of collection cylinder 1 is equipped with the threaded hole that communicates the storage cavity 101, and the threaded hole is inserted with the adjusting rod 4, and one end of adjusting rod 4 is fixedly provided with the connecting rod 401 in the storage cavity 101, and the one end of connecting rod 401 away from adjusting rod 4 is inserted in bottom disc 2 and is fixedly connected with the top of taper head 3.

[0025] In at least one embodiment, the two sides of the top of the collection cylinder 1 are fixedly provided with a fixed seat 102, and the fixed seat 102 is provided with a support rod 5. When the collection cylinder 1 is pressed into the soil, the support rod 5 on the fixed seat 102 is easily gripped to press and lift the collection cylinder 1, thereby improving the collection efficiency of the soil.

[0026] In at least one embodiment, the support rod 5 is rotatably connected to the fixed seat 102. After the collection is completed, the support rod 5 can be rotated and recovered through the fixed seat 102, thereby reducing the occupied space of the equipment and facilitating the storage and carrying of the equipment.

[0027] In at least one embodiment, the number of inclined holes 202 is multiple and is arranged in a circumferential direction of the counterbore 201. The multiple inclined holes 202 ensure that the soil in the counterbore 201 can effectively enter the storage cavity 101, thereby improving the collection efficiency of the soil.

[0028] In at least one embodiment, the depth of the counterbore 201 is greater than the height of the taper head 3. After the collection operation is completed, the taper head 3 can be recovered into the counterbore 201 on the bottom disc 2 by rotating the adjusting rod 4, thereby avoiding the exposure of the taper head 3 and avoiding the collision between the taper head 3 and the outside, thereby ensuring the safety of the equipment and the personnel.

[0029] In at least one embodiment, the outer wall of the bottom of the collection cylinder 1 is provided with an external thread segment, and the bottom disc 2 is threadedly sleeved on the collection cylinder 1. By rotating the bottom disc 2 along the bottom of the collection cylinder 1, the bottom disc 2 can be installed and detached from the collection cylinder 1, thereby facilitating the cleaning of the storage cavity 101.

[0030] In at least one embodiment, the top of the taper head 3 is provided with a cylindrical segment matched with the counterbore 201. By providing the cylindrical segment on the top of the taper head 3, the opening below the counterbore 201 can be effectively closed when the taper head 3 descends along the counterbore 201, thereby improving the closing effect.

[0031] In at least one embodiment, the outer wall of the collection cylinder 1 is provided with a scale in the vertical direction, and the scale facilitates the staff to intuitively observe the insertion depth, thereby improving the soil collection accuracy.

[0032] When collecting soil, the staff aligns the collection cylinder 1 with the soil area to be sampled, and then rotates the adjusting rod 4 on the collection cylinder 1, so that the adjusting rod 4 drives the connecting rod 401 at the bottom and the cone head 3 to descend. When the top of the cone head 3 descends to the level of the opening below the counterbore 201, the descent is stopped. At this time, the top of the cone head 3 closes the opening at the bottom of the counterbore 201. Then the staff presses the collection cylinder 1 down along the ground. The collection cylinder 1 drills into the soil below through the cone head 3. At this time, the closure of the counterbore 201 by the cone head 3 prevents the surface soil from entering the storage cavity 101 from the counterbore 201, thereby ensuring the accuracy of the collection. When drilling to the depth at which soil collection is required, the staff rotates the adjusting rod 4, so that the adjusting rod 4 drives the connecting rod 401 and the cone head 3 to rise. When the top of the cone head 3 abuts against the top wall of the counterbore 201, the rising is stopped. At this time, the storage cavity 101 in the collection cylinder 1 is in communication with the outside through the inclined hole 202 on the bottom disc 2 and the counterbore 201. Then the staff continues to press the collection cylinder 1 down, so that the collection cylinder 1 descends while the soil below the bottom disc 2 enters the storage cavity 101 from the counterbore 201 and the inclined hole 202. When the collection of the soil in the collection section is completed, the staff rotates the adjusting rod 4 again, so that the adjusting rod 4 drives the cone head 3 to descend, thereby closing the counterbore 201 with the cone head 3. This avoids the soil in the storage cavity 101 from falling out of the inclined hole 202 and the counterbore 201 when the collection cylinder 1 is removed. When the soil in the storage cavity 101 needs to be removed, the cone head 3 is retracted to the top of the counterbore 201 by rotating the adjusting rod 4. Then the soil in the storage cavity 101 can be poured out. The operation is convenient, and the accuracy of collecting the soil at the sampling depth is ensured.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, and not to limit them. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art will understand that they can still modify the technical solutions described in the foregoing embodiments, or make equivalent replacements for some technical features. Such modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
