Description

Technical Field

[0001] The utility model discloses a silt sampler and belongs to the technical field of silt sampling. Background Art

[0002] With the continuous development of large-scale engineering construction in the construction, municipal engineering, transportation and other industries, the level of survey and design has been greatly improved, and the requirements for taking soil samples have also increased accordingly.

[0003] The document with prior art publication number CN115420547A provides a silt sampler for geotechnical engineering investigation. In the related technology of the device, drilling sampling is carried out through the mutual cooperation of multiple structures, thereby solving the problem that traditional samplers are difficult to quickly penetrate into the silt for sampling. Secondly, the present invention seals the bottom open end of the hollow sampling drill rod through the mutual cooperation of multiple structures, thereby preventing the silt in the hollow sampling drill rod from scattering, further improving the sampling effect of the sampler, and is worthy of promotion and use.

[0004] Although the above-mentioned prior art solution can achieve the beneficial effects related to the prior art structure, it still has the following defects: the device uses the pressing flexible metal sealing plate to seal the bottom open end of the hollow sampling drill rod to limit the sampling silt inside the hollow sampling drill rod, but the hollow sampling drill rod is inserted into the silt and will enter the limiting guide tube to cause blockage, thereby blocking the flexible metal sealing plate from extending and retracting to limit the sampling silt inside the hollow sampling drill rod. In view of this, we propose a silt sampler. Summary of the invention

[0005] In view of the deficiencies in the prior art, the utility model aims to provide a silt sampler, which utilizes the limited lifting and lowering action of the pressed tooth sleeve plate that fits the sliding groove inside the sampling barrel, thereby driving the closing plate of the meshing transmission to flip, thereby sealing the sample collected in the sampling barrel. At the same time, the pressed tooth sleeve plate that fits the groove completely can effectively avoid the blockage of the groove, thereby improving the interception and collection effect of the sample in the sampling barrel.

[0006] To achieve the above-mentioned purpose, the utility model provides a silt sampler, comprising a holding tube rod, wherein the holding tube rod has an inner cavity;

[0007] The sampling barrel is arranged at the bottom of the holding barrel rod, the holding barrel rod is detachably connected to the sampling barrel, and a closing plate is arranged inside the sampling barrel;

[0009] The push rod plate is used to push the sample in the sampling tube to discharge. The push rod plate is axially sleeved in the inner cavity of the holding tube rod and is slidably connected thereto.

[0010] By adopting the above technical scheme, the pressing tooth sleeve plate that fits the sliding groove inside the sampling barrel is used to limit the lifting and lowering action, thereby driving the closing plate of the meshing transmission to flip, and the sample collected in the sampling barrel is sealed. At the same time, the pressing tooth sleeve plate that fully fits the groove can effectively avoid the blockage of the groove, thereby improving the interception and collection effect of the sample in the sampling barrel.

[0011] Furthermore, the holding tube rod is threadably connected to the sampling tube.

[0012] Furthermore, a meshing groove is arranged on the pressed gear sleeve plate, and a gear is arranged on the closing plate corresponding to the meshing groove, and the gear meshes with the meshing groove for transmission.

[0013] By adopting the above technical solution, the closing plate is meshed and flipped by utilizing the lifting and lowering movement of the pressed tooth sleeve plate, thereby driving the closing plate to close the sampling tube, thereby achieving the sealing of the sample in the sampling tube.

[0014] Furthermore, an adjusting screw is provided on the pressed gear sleeve plate, the adjusting screw is threadedly connected to the pressed gear sleeve plate, a through groove is opened in the sampling tube corresponding to the adjusting screw, and the adjusting screw is matched with the open groove to limit the pressed gear sleeve plate from sliding along the sampling tube.

[0015] By adopting the above technical solution, the threaded pressed gear sleeve plate is driven to move up and down by rotating the adjusting screw, so that the pressed gear sleeve plate can fix the position of the closing plate after the meshing transmission is turned over.

[0016] Furthermore, a treadle plate is provided on the external sliding sleeve of the gripping tube rod, and the treadle plate is pressed and limited with the gripping tube rod through a fastening screw threadedly connected thereto.

[0017] By adopting the above technical solution, a hoe is formed by using the threaded disassembled gripping barrel and the treading disc to remove the debris on the surface of the rock and soil, making it convenient to collect and use the sample powder. The circular treading disc can effectively improve the treading effect of the treading disc, making it convenient to drive the device to press down and take soil.

[0018] Furthermore, a non-slip rubber sleeve is provided on the gripping tube rod.

[0019] The utility model provides the following technical effects:

Preferably, the gripping tube rod 1 and the sampling tube 2 are threadedly connected.

[0029] The silt sampler utilizes the limited lifting and lowering action of the pressed tooth sleeve plate 3 that fits the internal through groove of the sampling tube 2, thereby driving the closing plate 21 of the meshing transmission to flip, and seals the sample collected in the sampling tube 2. At the same time, the pressed tooth sleeve plate 3 that fits the through groove completely can effectively avoid the blockage of the through groove, thereby improving the interception and collection effect of the sample in the sampling tube 2.

[0030] Reference Figure 3 and Figure 1The pressing gear sleeve plate 3 is provided with an engagement groove, and the closing plate 21 is provided with a gear 22 corresponding to the engagement groove, and the gear 22 is engaged with the engagement groove for transmission.

[0031] The silt sampler utilizes the pressing gear sleeve plate 3 to move up and down so that the closing plate 21 engages and flips, thereby driving the closing plate 21 to close the sampling tube 2, thereby sealing the sample in the sampling tube 2.

[0032] Reference Figure 4 and Figure 1 An adjusting screw 31 is provided on the pressed gear sleeve plate 3, and the adjusting screw 31 is threadedly connected to the pressed gear sleeve plate 3. A through groove is opened in the sampling tube 2 corresponding to the adjusting screw 31, and the adjusting screw 31 is matched with the open groove to limit the pressed gear sleeve plate from sliding along the sampling tube 2.

[0033] The silt sampler utilizes the pressing gear sleeve plate 3 to move up and down so that the closing plate 21 engages and flips, thereby driving the closing plate 21 to close the sampling tube 2, thereby sealing the sample in the sampling tube 2.

[0034] Reference Figure 2 and Figure 1 A tread plate 11 is provided on the outer sliding sleeve of the holding tube rod 1, and the tread plate 11 is pressed and limited with the holding tube rod 1 through a fastening screw threadedly connected thereto.

[0035] The silt sampler utilizes the pressing gear sleeve plate 3 to move up and down so that the closing plate 21 engages and flips, thereby driving the closing plate 21 to close the sampling tube 2, thereby sealing the sample in the sampling tube 2.

[0036] The working principle of the utility model is as follows: first, the operator removes the holding tube rod 1 which is threadedly connected to one end of the sampling tube 2, and then moves the pedal plate 11 fixed and limited by the tightening screw outside the holding tube rod 1 to the bottom end of the thread of the holding tube rod 1, so that the removed holding tube rod 1 and the pedal plate 11 form a hoe, and then the formed hoe is used to dig out the surface soil of the rock and soil to be sampled. After digging to an appropriate depth, the disassembled holding tube rod 1 is threadedly connected and fixed to the sampling tube 2 again, and the pedal plate 1 is adjusted. 1, the sampling tube 2 is inserted into the rock and soil pit to collect the silt. At this time, as the sampling tube 2 is inserted into the soil layer, the push rod plate 4 of the sliding limit inside the sampling tube 2 is squeezed by the silt collected inside the sampling tube 2, and the limit moves upward. Then, the adjusting screw 31 connected to the external thread of the pressing tooth sleeve plate 3 is manually rotated to drive the pressing tooth sleeve plate 3 to limit and move downward in the sampling tube 2, and mesh with the gear 22 fixedly installed on one side of the closing plate 21 to drive the closing plate 21 turned into the groove of the sampling tube 2. Figure 3The state is reversed, thereby closing the silt collected in the sampling tube 2. Finally, the pressed tooth sleeve plate 3 that moves downward in the device for pulling out the soil layer is returned to its original position, and the rising push rod plate 4 is pushed to discharge the silt in the sampling tube 2 into the container for collecting the sample.
