Technical Field
[0001] The present application relates to the field of soil sampling devices, and in particular to a ring knife sampler. Background Art
[0002] Nowadays, in the construction fields of municipal administration, transportation, water conservancy, etc., when accepting projects involving backfilling and replacement, it is usually necessary to test the compaction and moisture content of the backfilled soil. Among them, the more common method is to use a ring knife sampler to sample the soil on site, and then measure the corresponding parameters of the soil samples.
[0003] The knife ring sampler includes a sampling knife ring and a knocking handle. When in use, first measure the deadweight of the sampling knife ring, then place the sampling knife ring on the soil surface on site, then place the knocking handle against the top of the sampling knife ring and knock the knocking handle. The sampling knife ring is fully inserted into the soil, and the soil completely fills the sampling knife ring, then the sampling knife ring is dug out of the soil, and the whole of the sampling knife ring and soil is sent to the laboratory for measurement to ensure the integrity of the soil measurement process.
[0004] However, in the actual sampling process, tools (such as a shovel) are needed to dig out the sampling ring cutter, which causes great damage to the road surface; and in the process of digging out the sampling ring cutter, there is a possibility that the soil in the sampling ring cutter will partially fall off, resulting in poor soil sampling results. Utility Model Content
[0005] In order to improve the soil sampling effect, the present application provides a ring knife sampler.
[0006] The present application provides a ring knife sampler adopting the following technical solution:
[0007] A ring knife sampler comprises a tubular front knife body, a sampling ring knife and a knocking handle, wherein one end of the front knife body faces the soil and the other end is provided with an installation cavity, the sampling ring knife is coaxially inserted in the installation cavity, and the knocking handle is used to simultaneously push the front knife body and the sampling ring knife into the soil.
[0008] By adopting the above technical solution, when sampling, the handle is struck to insert the front blade body and the sampling ring blade into the soil at the same time; when taking out the soil sample, the front blade body is repeatedly shaken, and then the front blade body is taken out, and then the sampling ring blade is separated from the front blade body; thereby reducing the damage to the road surface; and, the front end of the front blade body is also filled with soil, which has a better protective effect on the soil sample in the sampling ring blade, reduces the possibility of the soil sample in the sampling ring blade falling off, and improves the soil sampling effect.
[0009] Optionally, the knocking handle is passed through and threadedly connected to an end of the front cutter body facing away from the soil, and the knocking handle is pressed against the sampling ring cutter.
[0010] By adopting the above technical solution, after the striking handle pushes the front blade body into the soil, the soil outside the front blade body can be loosened by simply holding the striking handle and swinging it, so as to take out the front blade body and the soil adsorbed inside; the striking handle and the front blade body are threadedly connected to each other, so that the stability of the connection between the striking handle and the front blade body can be ensured when the front blade body is controlled to swing in the soil.
[0011] Optionally, the striking handle is formed with an abutment flange, which abuts against an opening edge of the front blade body at one end facing away from the soil. A carrying ring is sleeved and fixed on the opening edge of the front blade body, and the carrying ring abuts against the abutment flange.
[0012] By adopting the above technical solution, when the knocking handle is knocked, the load can be transferred to the load-bearing ring through the abutment flange, and then the front knife body is driven forward into the soil, thereby reducing the impact on the sampling ring knife; and reducing the possibility of deformation of the edge of the installation cavity opening, reducing the possibility of obstruction when the sampling ring knife is removed, and at the same time increasing the service life of the front knife body and the sampling ring knife.
[0013] Optionally, a plurality of support ribs are fixed to the outer wall of the front cutter body, and the support ribs are also fixed to the bearing ring.
[0014] By adopting the above technical solution, the load-bearing ring can be reinforced by the supporting ribs, so that the load-bearing ring has a better load-bearing capacity and improves the use effect.
[0015] Optionally, a plurality of pins are formed on the end of the front blade body facing away from the soil, and the pins are simultaneously plugged into the striking handle.
[0016] By adopting the above technical solution, when in use, the front blade body is abutted against the soil surface, and the sampling ring blade is installed, and then the knocking handle is installed so that the pin is plugged into the knocking handle, and then the knocking handle is knocked; secondly, the knocking handle is held and the front blade body is shaken, and finally the front blade body and the soil adsorbed on the inside are taken out, and the sampling ring blade is taken out.
[0017] Optionally, a sample ejection plate is formed on one end of the striking handle away from the latch, and the sample ejection plate is used to push in from one end of the front blade body away from the sampling ring blade and push the sampling ring blade away from the front blade body.
[0018] By adopting the above technical solution, when the sampling ring knife needs to be separated from the front knife body, the knocking handle is first removed, and then the front knife body is turned upside down so that the pin supports the front knife body to be suspended in the air, and the sampling ring knife faces downward, and then the sample withdrawal plate on the knocking handle is pressed against the inner soil of the front knife body away from the sampling ring knife end, and then the knocking handle is continued to be knocked to push the sampling ring knife out, so that the sampling ring knife removal process is more convenient.
[0019] Optionally, the striking handle is provided with a ventilation hole, which connects the inner space of the front blade body with the outside.
[0020] By adopting the above technical solution, when the front blade body is inserted into the soil, the ventilation holes can facilitate the air flow inside the front blade body to flow outward, thereby alleviating the air pressure resistance during the insertion process of the front blade body.
[0021] Optionally, the inner diameter of the sampling ring cutter is smaller than the inner diameter of the end of the front cutter body facing the soil.
[0022] By adopting the above technical solution, after the front blade body is pre-inserted into the soil, when the sampling ring knife is inserted into the soil inside the front blade body, the soil sample also has a better adsorption effect on the sampling ring knife. When the sampling ring knife is subsequently separated from the front blade body, the possibility of the soil sample falling off from the sampling ring knife is reduced, thereby ensuring the soil sampling effect.
[0023] In summary, the present application includes at least one of the following beneficial technical effects:
[0024] 1. Knock the knock handle to insert the front blade body and the sampling ring blade into the soil at the same time; when taking out the soil sample, repeatedly shake the front blade body, then take it out, and then separate the sampling ring blade from the front blade body; thereby reducing the damage to the road surface; and the soil filled in the front end of the front blade body has a better protective effect on the soil sample in the sampling ring blade, reducing the possibility of the soil sample in the sampling ring blade falling off, and improving the soil sampling effect;
[0025] 2. When the sampling ring knife needs to be separated, first turn the front knife body upside down so that the pin supports the front knife body to be suspended in the air, then place the sample withdrawal plate on the knocking handle against the inner soil of the front knife body away from the end of the sampling ring knife, and then continue to knock to push the sampling ring knife out, making the sampling ring knife removal process more convenient.

DETAILED DESCRIPTION
[0031] The following is combined with Figure 1-4 This application is described in further detail.
[0032] The embodiment of the present application discloses a ring knife sampler.
[0033] Embodiment 1:
[0034] Reference Figure 1 A knife ring sampler comprises a front knife body 1, a sampling knife ring 2 and a knocking handle 3. The front knife body 1 extends vertically and is arranged as a tubular structure. An upper opening mounting cavity 11 is arranged inside the upper end of the front knife body 1. The sampling knife ring 2 is plugged into the mounting cavity 11. The sampling knife ring 2 is arranged coaxially with the front knife body 1, and the inner diameter of the sampling knife ring 2 is smaller than the inner diameter of the lower part of the front knife body 1.
[0035] Reference Figure 1 and Figure 2 The knocking handle 3 includes an integrally formed push plate 34 and a knocking column 35 . The push plate 34 is penetrated and threadedly connected to the opening edge of the mounting cavity 11 . The knocking column 35 is located on a side of the push plate 34 away from the front blade body 1 .
[0036] When in use, install the sampling ring knife 2 in the installation cavity 11 on the front blade body 1, and then install the knocking handle 3 on the front blade body 1, so that the knocking handle 3 presses the sampling ring knife 2 tightly. Secondly, the lower end of the front blade body 1 is abutted against the soil surface, and then the knocking handle 3 is knocked to make the front blade body 1 and the sampling ring knife 2 inserted into the soil. Then, the knocking handle 3 can be held and shaken to loosen the soil on both sides of the front blade body 1, and then the knocking handle 3 is held to remove the front blade body 1 from the soil, so that the sampled soil remains in the front blade body 1. Finally, the knocking handle 3 is disassembled, and the sampling ring knife 2 is separated from the front blade body 1, so that the sampling ring knife 2 and the soil sample inside can be sent to the laboratory for testing.
[0037] Thereby, the damage to the road surface is reduced; and, in the process of removing the front blade body 1 from the soil (even if it is removed by digging), the front end of the front blade body 1 is also filled with soil, which has a better protective effect on the soil sample in the sampling ring blade 2, reduces the possibility of the soil sample in the sampling ring blade 2 falling off, and improves the soil sampling effect.
[0038] In addition, the inner diameter of the sampling ring knife 2 is set to be smaller than the inner diameter of the lower part of the front blade body 1, so that after the front blade body 1 is pre-inserted into the soil, when the sampling ring knife 2 is inserted into the soil inside the front blade body 1, the soil sample can also have a better adsorption effect on the sampling ring knife 2. When the sampling ring knife 2 is subsequently separated from the front blade body 1, the possibility of the soil sample falling out of the sampling ring knife 2 is reduced.
[0039] In addition, the striking handle 3 and the front blade body 1 are threadedly connected to each other, so that when the front blade body 1 is controlled to swing in the soil, the connection between the striking handle 3 and the front blade body 1 is stable.
[0040] Reference Figure 2 The knocking handle 3 is provided with a ventilation hole 33, which penetrates through the push plate 34 and connects the internal space of the front blade body 1 with the outside. When the front blade body 1 is inserted into the soil, the air flow inside the front blade body 1 can flow outward, thereby alleviating the air pressure resistance during the insertion of the front blade body 1.
[0041] Reference Figure 2 and Figure 3 The upper edge of the push plate 34 in the knocking handle 3 protrudes outward to form an abutting flange 31, and the abutting flange 31 abuts against the opening edge of the installation cavity 11. In addition, a bearing ring 12 is fixedly mounted on the opening edge of the installation cavity 11, and the bearing ring 12 and the abutting flange 31 abut against each other. The outer wall of the upper end of the front blade body 1 is provided with a plurality of supporting ribs 121, and the plurality of supporting ribs 121 are distributed along the circumference of the front blade body 1. The supporting ribs 121 extend vertically, and the supporting ribs 121 are fixed to the bearing ring 12 and the outer wall of the front blade body 1 at the same time.
[0042] When the knocking handle 3 is knocked, the load can be transferred to the carrying ring 12 through the abutting flange 31, and then the front blade body 1 is driven forward into the soil, reducing the impact on the sampling ring blade 2. In addition, the carrying ring 12 can also be reinforced by the support ribs 121, so that the carrying ring 12 has a better load-bearing capacity, thereby reducing the possibility of deformation of the opening edge of the installation cavity 11, reducing the possibility of obstruction when the sampling ring blade 2 is taken out, and at the same time increasing the service life of the front blade body 1 and the sampling ring blade 2.
[0043] The implementation principle of Example 1 is as follows: by knocking the knocking handle 3, both the front blade body 1 and the sampling ring blade 2 can be inserted into the soil. Then, the knocking handle 3 can be held and shaken to loosen the soil on both sides of the front blade body 1, and then the knocking handle 3 can be held to remove the front blade body 1 from the soil, so that the sampled soil is retained in the front blade body 1, and finally the sampling ring blade 2 can be separated from the front blade body 1. Thus, the damage to the road surface is reduced; and in the process of removing the front blade body 1 from the soil, the soil sample in the sampling ring blade 2 has a better protective effect, reducing the possibility of the soil sample in the sampling ring blade 2 falling off, and improving the soil sampling effect.
[0044] Embodiment 2:
[0045] Reference Figure 4 The difference between this embodiment and the first embodiment is that a plurality of latches 13 are formed on the opening edge of the mounting cavity 11 on the front blade body 1, and the latches 13 extend along the side of the front blade body 1 away from the soil. A plurality of through holes corresponding to the latches 13 are formed in the push plate 34 in the knocking handle 3, so that when installing the knocking handle 3, it is only necessary to place the knocking handle 3 against the upper end of the front blade body 1, so that the plurality of latches 13 are respectively inserted into the plurality of through holes.
[0046] When in use, the front blade body 1 is placed against the soil surface, and then the knocking handle 3 is installed so that the pin 13 is inserted into the through hole on the knocking handle 3, and then the knocking handle 3 is knocked. Then the knocking handle 3 is held and the front blade body 1 is shaken, and finally the front blade body 1 and the soil adsorbed inside are removed.
[0047] Since the latch 13 cooperates with the striking handle 3, when the front blade body 1 is controlled to swing to loosen the soil on both sides, the connection between the front blade body 1 and the striking handle 3 also has better stability, and the installation process of the striking handle 3 is more convenient.
[0048] In addition, when the sampling ring knife 2 needs to be separated from the front knife body 1, the knocking handle 3 is first removed, and then the front knife body 1 is turned upside down, so that the pin 13 supports the front knife body 1 to be suspended in the air, and the sampling ring knife 2 is facing downward, and then the upper end of the knocking handle 3 is abutted against the inner soil of the front knife body 1 away from the end of the sampling ring knife 2, and then the knocking handle 3 is continued to be knocked to push the sampling ring knife 2 out, making the operation process more convenient.
[0049] Reference Figure 4 At this time, on the knocking handle 3, the end of the knocking column 35 away from the push plate 34 is formed with a sample withdrawal plate 32, so that the sample withdrawal plate 32 can adapt to the end of the front knife body 1 away from the sampling ring knife 2. Then, the sample withdrawal plate 32 on the knocking handle 3 can be used to push out the sampling ring knife 2, so that the pushing effect is better.
[0050] The implementation principle of Example 2 is as follows: when in use, the front blade body 1 is placed against the soil surface, and then the knocking handle 3 is installed so that the pin 13 is inserted into the through hole on the knocking handle 3, and then the knocking handle 3 is knocked. Then the knocking handle 3 is held and the front blade body 1 is shaken, and finally the front blade body 1 and the soil adsorbed inside are taken out, and the sampling ring blade 2 is separated.
[0051] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
