Description

Technical Field

[0001] The utility model relates to the technical field of engineering supervision equipment, and particularly relates to an engineering supervision soil sampling device. Background Art

[0002] With the continuous development of the construction engineering industry, all sectors of society have higher and higher requirements for engineering supervision work. Engineering supervision work can promote the smooth progress of the project and ensure the safety and quality of the project. During the engineering supervision process, it is necessary to often sample and detect the soil to ensure that the construction will not cause environmental impact on the soil.

[0003] At present, the existing soil sampling mechanism includes a sampling cylinder, a screw rod and a spiral sampling rod. The screw rod and the spiral sampling rod are connected by using screws. When it is necessary to take out the soil after sampling, the spiral sampling rod is disassembled by loosening the screws, and then the spiral sampling rod filled with soil is taken out from the sampling cylinder. However, since the connection method between the spiral sampling rod and the screw rod is fixed by screws, when the screw rod is rotated to drive the spiral sampling rod into the soil, the screws need to bear the torque generated during rotation, which easily causes the screws to bend and deform, making it difficult to loosen the screws, resulting in difficulty in disassembling the spiral sampling rod and affecting the subsequent detection progress of the soil. Summary of the Utility Model

[0004] The purpose of the utility model is to design an engineering supervision soil sampling device, which can solve the problems mentioned in the background art.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] An engineering supervision soil sampling device includes a sampling cylinder and a spiral sampling rod located inside the sampling cylinder. The top of the sampling cylinder is fixedly connected with a sleeve. A screw rod is arranged inside the sleeve. The inner wall of the sleeve is provided with a first internal thread threadedly connected with the screw rod. A plurality of limiting blocks are circumferentially distributed on the outer wall of one end of the screw rod. One end of the spiral sampling rod close to the screw rod is provided with a groove. The bottom of the groove is provided with a limiting groove adapted to the limiting blocks one by one. A positioning mechanism for pressing the limiting blocks in the limiting grooves is detachably arranged inside the groove.

[0007] Further, the positioning mechanism includes a slider slidably connected to one end of the screw rod close to the limiting block. The outer wall of the slider is provided with an external thread. The inner wall of the groove is provided with a second internal thread threadedly connected with the external thread.

[0008] Furthermore, a nut is arranged on the outer wall of one end of the slider away from the limiting block.

[0009] Further, one end of the screw rod away from the limiting block is fixedly connected with a turntable.

[0010] Further, a drill bit is provided at one end of the spiral sampling rod away from the screw.

[0011] Further, a cover is provided at the bottom of the sampling cylinder.

[0012] Further, three positioning cone heads are circumferentially distributed on the outer wall of the bottom of the sampling cylinder.

[0013] Further, both sides of the sleeve are fixedly connected to the top of the sampling cylinder through support rods.

[0014] The beneficial effects of the present utility model are as follows:

[0015] By adapting the limit block of the screw to the limit groove of the spiral sampling rod and pressing the limit block in the limit groove by the positioning mechanism, when driving the spiral sampling rod into the soil by rotating the screw, the limit block and the limit groove bear the torsional force during rotation. When disassembling the spiral sampling rod, only the positioning mechanism needs to be disassembled, and the spiral sampling rod will not be difficult to disassemble due to the torsional force, avoiding affecting the subsequent soil detection progress.

[0024] To further elaborate on the technical means and effects adopted by the present utility model to achieve the predetermined utility model purpose, the following combines the attached drawings and preferred embodiments to detail the specific implementation mode, structure, features and their effects of the present utility model as follows.

[0025] As Figures 1-5 shown, an engineering supervision soil sampling device includes a sampling cylinder 1 and a spiral sampling rod 2 located inside the sampling cylinder 1. A sleeve 3 is provided above the sampling cylinder 1. Both sides of the sleeve 3 are fixedly connected to the top of the sampling cylinder 1 through a support rod 17. A screw 4 is provided inside the sleeve 3. The inner wall of the sleeve 3 is provided with a first internal thread 5 that is threadedly connected to the screw 4. By rotating the screw 4, the screw 4 can move up and down inside the sleeve 3; eight limit blocks 6 are circumferentially distributed on the outer wall of one end of the screw 4. The end of the screw 4 away from the limit block 6 is fixedly connected to a turntable 13, which can make it more labor-saving when rotating the screw 4;

[0026] One end of the spiral sampling rod 2 close to the screw 4 is provided with a groove 7. The bottom of the groove 7 is provided with a limit groove 8 that is adapted to the limit block 6 one by one. The limit block 6 and the limit groove 8 are used to bear the torsional force during rotation; One end of the screw 4 close to the limit block 6 is slidably connected to a slide block 9, so that the slide block 9 can slide freely along the screw 4; An external thread 10 is provided on the outer wall of the slide block 9. The inner wall of the groove 7 is provided with a second internal thread 11 that is threadedly connected to the external thread 10. By tightening the connection between the external thread 10 and the second internal thread 11, the slide block 9 can press the limit block 6 tightly in the limit groove 8, so that the spiral sampling rod 2 and the screw 4 are fixedly connected; A nut 12 is provided on the outer wall of the end of the slide block 9 away from the limit block 6. By using a wrench tool to turn the nut 12, the connection between the slide block 9 and the groove 7 can be loosened; A drill bit 14 is provided at the end of the spiral sampling rod 2 away from the screw 4. A sealing cover 15 is provided at the bottom of the sampling cylinder 1 to prevent the taken soil from leaking out from the bottom of the sampling cylinder 1; Three positioning cone heads 16 are circumferentially distributed on the outer wall of the bottom of the sampling cylinder 1 to position and fix the sampling cylinder 1 and prevent the sampling cylinder 1 from shifting and rotating during the sampling process.

[0027] Working principle:

[0028] As Figures 1-5 shown, when the soil sampling device is in use, first place the sampling cylinder 1 on the soil surface where soil sampling is required, and insert the positioning cone head 16 into the soil to position and fix the sampling cylinder 1;

[0029] Then manually rotate the turntable 13 to drive the screw rod 4 to rotate. When rotating the screw rod 4 to drive the spiral sampling rod 2 to rotate into the soil for soil sampling, the limiting block 6 and the limiting groove 8 are used to bear the torsion force generated during rotation. After the soil sampling is completed, rotate the turntable 13 in the reverse direction to drive the screw rod 4 to rotate, so that the spiral sampling rod 2 can store the soil sampling sample into the sampling cylinder 1. Then cover the bottom of the sampling cylinder 1 with the cover 15 to prevent the taken-out soil from leaking out from the bottom of the sampling cylinder 1;

[0030] When it is necessary to take out the soil in the sampling cylinder 1, use a wrench tool to turn the nut 12, thereby loosening the connection between the external thread 10 and the second internal thread 11, so that the slider 9 completely leaves the groove 7, completing the disassembly of the spiral sampling rod 2. Finally, open the cover 15 and take out the spiral sampling rod 2 and the soil from the sampling cylinder 1.

[0031] The above are only the preferred embodiments of the present invention, and do not impose any form of limitation on the present invention. Although the present invention has been disclosed above with the preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to equivalent embodiments by using the disclosed technical content within the scope of the technical solution of the present invention. However, as long as it does not depart from the content of the technical solution of the present invention, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
