Description

Technical Field

[0001] This utility model relates to the field of soil sampling tools for geological exploration, and in particular to a soil sampling tool that can be quickly disassembled and removed from the soil. Background Technology

[0002] Geological exploration is an investigation and research activity that uses various means and methods to explore and detect geology, determine suitable bearing strata, determine the foundation type based on the bearing capacity of the bearing strata, and calculate foundation parameters. It is a survey and research activity that discovers industrially significant mineral deposits during mineral prospecting, provides mineral reserves and geological data needed for mine construction design to ascertain the quality and quantity of minerals and the technical conditions for mining and utilization, and investigates and studies the geological conditions such as rocks, strata, structures, minerals, hydrology, and landforms in a certain area. In geological exploration, it is necessary to use soil samplers to sample and test the soil in the exploration area.

[0003] Currently, there are various equipment or devices available on the market for soil sampling, but they all have different drawbacks. For example: 1. Sampling soil by drilling rigs in mountainous areas is difficult to transport and maintain, has high operating costs, and requires power, making sampling impossible in areas without power. 2. Sampling is done using a Luoyang shovel and probe, but this method cannot obtain core samples and the exploration depth is insufficient. 3. Sampling is done using a dedicated manual soil sampler, but this method is difficult to disassemble after sampling, and it is difficult to remove soil clumps from inside the sampler, resulting in slow efficiency and inconvenience.

[0004] Therefore, it is necessary to design a soil sampler that is easy to disassemble and remove soil from. Utility Model Content

[0005] Therefore, the purpose of this utility model is to overcome the shortcomings of the existing technology and provide a soil sampler that can quickly remove soil.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A quick-release and quick-removal soil sampler, comprising:

[0008] Soil sampling cylinder, connecting rod, pin, guide sleeve, and counterweight rod;

[0009] The lower end of the soil sampling cylinder is open, and the upper end is provided with a first connecting seat.

The docking hole allows the piston rod of an external hydraulic jack to extend into it.

[0010] The lower end of the connecting rod is provided with a second connecting seat, and the second connecting seat is provided with a second pin hole extending radially along the connecting rod. The second connecting seat can be inserted into the mating hole so that the axes of the first pin hole and the second pin hole overlap.

[0011] The pin is used to insert into the first pin hole and the second pin hole;

[0012] The guide sleeve is movably sleeved on the upper end of the connecting rod. The guide sleeve can reciprocate along the axial direction of the connecting rod. A limit structure is provided between the guide sleeve and the connecting rod. The limit structure is used to prevent the guide sleeve from detaching from the connecting rod upwards.

[0013] The lower end of the counterweight rod is detachably connected to the upper end of the guide sleeve, and the interior of the counterweight rod is hollow to allow the connecting rod to extend into it.

[0014] The soil sampler of this application, which allows for quick disassembly and removal of soil, enables rapid disassembly of the soil sample tube and quick separation of soil clumps from the tube.

[0018] In one embodiment, the lower end of the guide sleeve is provided with a plurality of buffer posts for impacting the second connecting seat.

[0019] In one embodiment, a plurality of the buffer posts are evenly arranged circumferentially along the guide sleeve, and the buffer posts extend axially along the guide sleeve.

[0020] In one embodiment, the limiting structure includes a limiting ring and a limiting protrusion. The limiting ring is disposed at the lower end of the guide sleeve, and the limiting protrusion is disposed at the upper end of the connecting rod. The size of the limiting protrusion is larger than the inner diameter of the limiting ring, and the inner peripheral wall of the limiting ring is fitted to the outer peripheral wall of the connecting rod.

[0037] Please see Figures 1 to 9 This embodiment provides a soil sampler for quick disassembly and soil removal, which includes: a soil sampler 1, a connecting rod 2, a pin 6, a guide sleeve 3, and a counterweight rod 4.

[0038] The function of the soil sampling tube 1 is to insert it into the soil to take soil samples. The cylindrical structure of the soil sampling tube 1 can ensure the integrity of the soil after sampling and prevent it from falling off easily. In this embodiment, the lower end of the soil sampling tube 1 is open and the upper end is provided with a first connecting seat 12.

[0039] like Figure 1-6 As shown, the first connecting seat 12 is provided with a docking hole 121 extending axially along the soil sampling cylinder 1 and a first pin hole 122 extending radially along the soil sampling cylinder 1. The first pin hole 122 is connected to the docking hole 121, and the docking hole 121 is also connected to the interior of the soil sampling cylinder 1. The docking hole 121 allows the piston rod of an external hydraulic jack to extend into it. A piston core 13 is provided inside the soil sampling cylinder 1, and the piston core 13 is close to the docking hole 121.

[0040] The lower end of the connecting rod 2 is provided with a second connecting seat 21. The second connecting seat 21 is provided with a second pin hole 211 extending radially along the connecting rod 2. The second connecting seat 21 can be inserted into the mating hole 121 so that the axes of the first pin hole 122 and the second pin hole 211 overlap. The pin 6 is used to insert into the first pin hole 122 and the second pin hole 211. As can be seen from the above configuration, the soil sampling tube 1 and the connecting rod 2 can be detachably connected through the cooperation of the first connecting seat 12, the second connecting seat 21 and the pin 6. This facilitates the replacement of the soil sampling tube 1 and also ensures the integrity of the sampling. The soil sampled by the soil sampling tube 1 can be directly taken for testing by simply disassembling the soil sampling tube 1.

[0041] During connection, the connecting rod 2 is held so that the second connecting seat 21 is inserted into the mating hole 121 of the first connecting seat 12, and the first pin hole 122 and the second pin hole 211 are aligned so that their axes overlap. Then, the pin 6 is inserted into the first pin hole 122 and the second pin hole 211, thus fixing the first connecting seat 12 and the second connecting seat 21 to each other, completing the connection between the soil sampling cylinder 1 and the connecting rod 2. Disassembly is performed by reversing the above steps. After the soil sampling cylinder 1 is disassembled from the connecting rod 2, the first connecting seat 12 of the soil sampling cylinder 1 can be aligned with an external hydraulic jack. By operating the hydraulic jack, the piston rod of the hydraulic jack is pushed out, extending into the mating hole 121 to push the piston core 13, thereby pushing out the soil clods from the soil sampling cylinder 1. The operation is very convenient.

[0042] The guide sleeve 3 is movably sleeved on the upper end of the connecting rod 2. The guide sleeve 3 can reciprocate along the axial direction of the connecting rod 2. The guide sleeve 3 can cooperate with the outer peripheral wall of the connecting rod 2, thereby moving along the axial direction of the connecting rod 2 to guide the movement of the counterweight rod 4. The guide sleeve 3 can move to a position close to the soil sampling cylinder 1. A limit structure 23 is provided between the guide sleeve 3 and the connecting rod 2. The limit structure 23 is used to prevent the guide sleeve 3 from detaching from the connecting rod 2 upwards. The movement of the guide sleeve 3 towards the soil sampling cylinder 1 is not restricted by the limit structure. During disassembly, the soil sampling cylinder 1 can be disassembled from the connecting rod 2, and then the guide sleeve 3 can be slid out towards the soil sampling cylinder 1.

[0043] The lower end of the counterweight rod 4 is detachably connected to the upper end of the guide sleeve 3. The counterweight rod 4 is hollow inside to allow the connecting rod 2 to extend into it. It can be understood that the counterweight rod 4 can reciprocate along the axial direction of the connecting rod 2, following the guide sleeve 3. Because the counterweight rod 4 is hollow inside, the connecting rod 2 can extend into the counterweight rod 4 during axial displacement, thereby increasing the stroke.

[0044] One method of using the quick-release and quick-soil-removal soil sampler of this application is as follows:

[0045] Insert the soil sampling tube 1 of the soil sampler into the soil with the sampling point facing the ground. Then, hold the counterweight rod 4 and repeatedly operate the counterweight rod 4 vertically. When the counterweight rod 4 moves downward, the guide sleeve 3 also moves downward, so that the end of the guide sleeve 3 strikes the end of the second connecting seat 21 (e.g., Figure 5As shown in the diagram, the soil sampling cylinder 1 is then inserted downwards into the soil. When the counterweight rod 4 moves upwards, the guide sleeve 3 also moves upwards, moving away from the soil sampling cylinder 1 and storing gravitational potential energy for the next hammer blow. The distance of the guide sleeve 3 from the soil sampling cylinder 1 is limited by the limiting structure 23, so the guide sleeve 3 will not detach from the connecting rod 2. As can be seen from the above, by continuously operating the counterweight rod 4 up and down, the guide sleeve 3 can repeatedly hammer the second connecting seat 21, thereby causing the soil sampling cylinder 1 to continuously penetrate deeper into the soil and sample the soil. At this time, a hole is formed on the ground by the hammer blow of the soil sampling cylinder 1.

[0046] After the soil sampling cylinder 1 is filled with soil, the soil sampler can be pulled out from the hole. By removing the pin 6, the entire soil sampling cylinder 1 filled with soil can be disassembled from the connecting rod 2. The disassembled soil sampling cylinder 1 can be used with a hydraulic jack to push out the soil clods from the soil sampling cylinder 1.

[0047] After the soil in the soil sampling cylinder 1 is removed or a new soil sampling cylinder 1 is replaced, the soil sampler can be inserted into the formed hole again to take soil samples again until the required sampling depth is reached.

[0048] The above-described method of use can achieve the effect of vertical drilling. Of course, it is understood that, depending on the actual situation, it can also be horizontal or inclined drilling. That is to say, when using it, the soil sampling tube 1 is aligned with the sampling position, and the counterweight rod 4 is operated horizontally or obliquely to achieve the same effect as the vertical drilling described above, and the soil is sampled.

[0049] As can be seen from the above settings, the soil sampler of this application with quick disassembly and quick soil removal can quickly disassemble the soil sampler cylinder 1 and quickly separate the soil clods from the soil sampler cylinder 1. The operation is very convenient and helps to improve the efficiency of soil sampling and inspection.

[0050] To improve the coordination between the soil sampling cylinder 1 and the external hydraulic jack, such as Figure 7-9 As shown, preferably, the first connecting seat 12 can be fitted to an external hydraulic jack. The hydraulic jack includes a hydraulic cylinder 7 that accommodates a piston rod. The upper end of the hydraulic cylinder 7 is provided with a plug seat 72. The first connecting seat 12 is detachably connected to the plug seat 72. By detachably connecting the first connecting seat 12 to the plug seat 72, the soil sampling cylinder 1 and the hydraulic cylinder 7 can be fixed to each other. Thus, when the piston rod of the hydraulic jack is operated to push out and extend into the docking hole 121, the soil sampling cylinder 1 and the hydraulic cylinder 7 are prevented from separating from each other.

[0051] Specifically, the first connecting seat 12 has a pair of connecting protrusions 123 arranged symmetrically with respect to the soil sampling cylinder 1 along its axis, and the plug-in seat 72 has a positioning groove 721 that cooperates with the first connecting seat 12 and a limiting groove 722 that communicates with the side of the positioning groove 721.

[0052] like Figure 8 As shown, the first connecting seat 12 can be inserted into the positioning slot 721, such as... Figure 9 As shown, by rotating the first connecting seat 12, the connecting protrusion 123 can enter the limiting groove 722, thereby axially limiting the first connecting seat 12 and the plug-in seat 72. This arrangement makes it convenient to assemble and disassemble the first connecting seat 12 and the plug-in seat 72.

[0053] The counterweight 4 is relatively heavy, which increases the impact force and makes it easier and less strenuous for the user to operate. In this embodiment, due to the presence of the counterweight 4, its weight is relatively large, so it can store more gravitational potential energy when moved upwards, thus requiring less effort from the user when moving downwards.

[0054] like Figure 2 and 5 As shown, in order to reduce the impact pressure of the guide sleeve 3 on the second connecting seat 21 and prevent the second connecting seat 21 from being damaged, preferably, the lower end of the guide sleeve 3 is provided with multiple buffer posts 31 for impacting the second connecting seat 21. The contact area between the multiple buffer posts 31 and the second connecting seat 21 is larger than the contact area between the end of the guide sleeve 3 and the second connecting seat 21, thus it can reduce the impact pressure, thereby reducing damage and improving service life.

[0055] Specifically, in this embodiment, a plurality of buffer posts 31 are evenly arranged along the circumference of the guide sleeve 3, and the buffer posts 31 extend along the axial direction of the guide sleeve 3.

[0056] In this embodiment, the limiting structure 23 can restrict the guide sleeve 3 from detaching from the connecting rod 2. Its arrangement can be varied. Preferably, in this embodiment, the limiting structure 23 includes a limiting ring 231 and a limiting protrusion 232. The limiting ring 231 is located at the lower end of the guide sleeve 3, and the limiting protrusion 232 is located at the upper end of the connecting rod 2. The size of the limiting protrusion 232 is larger than the inner diameter of the limiting ring 231, and the inner circumferential wall of the limiting ring 231 fits into the outer circumferential wall of the connecting rod 2. With this arrangement, the movement of the guide sleeve 3 away from the soil sampling cylinder 1 is limited by the limiting protrusion 232, thereby preventing the guide sleeve 3 from detaching from the connecting rod 2. The inner circumferential wall of the limiting ring 231 fits into the outer circumferential wall of the connecting rod 2, allowing the guide sleeve 3 to move axially along the connecting rod 2, reducing movement deviation. In this embodiment, the limiting protrusion 232 is a cylindrical structure located at the end of the connecting rod 2.

[0057] Preferably, the opening edge of the soil sampling cylinder 1 is provided with a soil-shoveling blade. This blade allows for easier insertion into the soil, making it easier for the user and increasing its practicality.

[0058] Preferably, the soil sampling cylinder 1 is made of manganese alloy steel. Manganese alloy steel is a high-strength steel, mainly used in harsh working conditions that require resistance to impact, extrusion, and material abrasion. Therefore, the soil sampling cylinder 1 made of this material is durable and not easily damaged.

[0059] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
