Description

Technical Field

[0001] The utility model relates to the technical field of geotechnical engineering, in particular to a geotechnical engineering on-site sampling device. Background Art

[0002] All kinds of engineering projects on the ground, underground and in water are collectively referred to as civil engineering, and the part of civil engineering involving rock, soil, underground and water is called geotechnical engineering. When conducting various indicators in geotechnical engineering, various sampling instruments are needed to sample soil, water, etc. When sampling rock and soil, the traditional method is to directly insert a cylindrical or claw-shaped mechanical device into the ground to sample the soil. After sampling, the sample needs to be collected in a container and then brought back to the laboratory for testing and other operations. From the use of this type of sampling instrument, it can be seen that after the sample is taken out, an additional container needs to be prepared for separate collection. This requires the sampling instrument to not only be able to perform sampling, but also must have the function of being able to export the sample. Especially for cylindrical sampling instruments, how to remove the sample from the sampling cylinder is an indispensable function. Moreover, most of the samples taken by the sampling instrument are in block form and must be broken up first. Existing sampling instruments can only ensure sampling but cannot achieve crushing. Block samples also require larger capacity containers when collected. Utility Model Content

[0026] Reference Figure 1-8 , provides a geotechnical engineering site sampling device, including a ring-arranged assembly base 1, a sampling bucket 2 is fixedly installed on the top of the assembly base 1, an adjusting member 3 is fixedly installed on the top of the assembly base 1 on one side of the sampling bucket 2, and a sampling member 4 for sampling is provided at the bottom of the assembly base 1. The sampling member 4 can sample the soil at the geotechnical engineering site. After sampling, the assembly base 1 and the sampling bucket 2 can be flipped by the adjusting member 3, and then the sample in the sampling member 4 can automatically fall into the sampling bucket 2, and finally be collected uniformly.

[0027] The assembly base 1 is provided with an inlet 5, through which the rock and soil samples dropped from the sampling piece 4 can enter the sampling barrel 2. A vertical plate 6 is integrally provided on one side of the top of the assembly base 1, and a fan-shaped worm gear 7 is installed on the top of the vertical plate 6. The adjusting member 3 is fixedly mounted on the outer wall of the vertical plate 6 away from the sampling barrel 2, and the adjusting member 3 is connected to the fan-shaped worm gear 7 on the side facing the sampling barrel 2. An assembly shaft 17 is fixedly mounted at the center of the fan-shaped worm gear 7, and the assembly shaft 17 is rotatably connected to the adjusting member 3. The fan-shaped worm gear 7 can be rotated and adjusted by the adjusting member 3, and the fan-shaped worm gear 7 can drive the assembly base 1 to rotate around the assembly shaft 17 through the vertical plate 6, thereby driving the sampling barrel 2 to flip, so that the orientation between the sampling barrel 2 and the sampling piece 4 can be adjusted to each other, so that the sample in the sampling piece 4 can automatically fall into the sampling barrel 2 by gravity. A connecting strip 8 is fixedly installed between the side wall of the sector worm gear 7 facing the sampling barrel 2 and the assembly seat 1. The connecting strip 8 is arranged around the outside of the sampling barrel 2. The connecting strip 8 can increase the stability of the sector worm gear 7 when driving the assembly seat 1 to flip.

[0028] The assembly seat 1 is fixedly mounted with a vertical rod 13 at the center of one end face away from the sampling barrel 2, and an annular seat 12 is fixedly mounted on the end portion of the vertical rod 13 away from the assembly seat 1. A screw rod 14 is fixedly mounted on the center of one end face of the annular seat 12 away from the vertical rod 13. A connecting disk 15 is screwed onto the outside of the screw rod 14, and a plurality of first hinged seats 16 are fixedly mounted on the outer wall of the connecting disk 15. An adjusting disk 18 is also rotatably mounted between the assembly seat 1 and the annular seat 12, and a plurality of second hinged seats are fixedly mounted on the outer wall of the adjusting disk 18. 20, and the number of the first hinged seat 16 and the second hinged seat 20 is equal and corresponds one to one. The sampling member 4 includes sampling claws 23 equal to the number of the first hinged seat 16 and the second hinged seat 20. A hinged ear 24 is fixedly installed at the bottom of one end of the sampling claw 23 close to the screw rod 14. The hinged ear 24 is hinged to the first hinged seat 16. A third hinged seat 25 is fixedly installed on the side of the sampling claw 23 away from the screw rod 14. The third hinged seat 25 and the second hinged seat 20, which are arranged close to each other, are connected by a linkage rod 26.

[0029] When the adjusting disk 18 is subjected to external force and rotates between the annular seat 12 and the assembly seat 1, the adjusting disk 18 will drive one end of the linkage rod 26 to move synchronously through the second hinge seat 20, and the other end of the linkage rod 26 will drive the sampling claw 23 to move synchronously. The sampling claw 23 is connected to the connecting disk 15, so the connecting disk 15 will rotate outside the screw rod 14, and because the middle part of the connecting disk 15 is screwed to the screw rod 14, the connecting disk 15 will also change its position on the screw rod 14 while rotating. The connecting disk 15 will drive the hinged ear 24 of the sampling claw 23 to move through the first hinge seat 16. When the hinged ear 24 approaches the annular seat 12, all the sampling claws 23 will move close to each other, and then the rock and soil sample will be grabbed. When the adjusting disk 18 rotates in the opposite direction, the sampling claw 23 can release the grabbed sample.

[0031] A mesh plate 22 is installed inside the adjustment disk 18. The mesh plate 22 is arranged at an angle, and a drop opening 21 is provided between the mesh plate 22 and the inner side wall of the adjustment disk 18. The end of the sampling claw 23 away from the connecting disk 15 is also integrally provided with a claw tip 27. The sample falling from the sampling claw 23 can fall into the sampling port 5 through the drop opening 21 and finally enter the sampling barrel 2. The mesh plate 22 can break up the sample to ensure that the sample does not form large particles, thereby improving the subsequent collection efficiency.

[0032] The adjusting member 3 includes an assembly plate 28 arranged on the outside of the vertical plate 6 and arranged parallel to the vertical plate 6. A bearing seat 29 is fixedly installed on the side of the assembly plate 28 facing the vertical plate 6. The assembly shaft 17 is rotatably installed in the bearing seat 29. A flip motor 30 is also fixedly installed on the side of the assembly plate 28 facing the vertical plate 6. A worm 31 is fixedly installed on the output shaft end of the flip motor 30. The worm 31 is meshed with the fan-shaped worm gear 7. A handle rod 32 is fixedly installed on the side wall of the assembly plate 28 away from the vertical plate 6. By holding the handle rod 32 and starting the flip motor 30, the flip motor 30 can drive the fan-shaped worm gear 7 to rotate around the assembly shaft 17 through the worm 31, thereby driving the sampling barrel 2 and the assembly seat 1 to flip.

[0033] There are two handle bars 32 , and an extension sleeve 33 is sleeved on the outside of one end of the handle bar 32 away from the assembly plate 28 . A connecting rod 34 is fixedly connected between the two extension sleeves 33 , and a handle sleeve 35 is installed on the outside of the end of the extension sleeve 33 away from the handle bar 32 .

[0034] Through the above-mentioned scheme of the present invention, the present invention can adjust the sampling claws 23 through the adjustment disk 18, so that the sampling claws 23 are close to each other and the claw tips 27 are used to grab the rock and soil samples. After the sampling claws 23 are closely close to each other, the fan-shaped worm gear 7 can be adjusted by the worm 31 to realize the flipping of the assembly seat 1, so that the orientation between the sampling barrel 2 and the sampling claws 23 is flipped. At this time, when the sampling claws 23 are opened again, gravity can be used to make the sample automatically fall into the sampling barrel 2. The adjustment disk 18 is also provided with a mesh plate 22, which can break the sample and make it more convenient to remove the sample later.
