Description

Technical Field

[0001] This utility model belongs to the field of soil sampling technology, specifically relating to a shallow sampler. Background Technology

[0002] In fields such as geological exploration, the collection of soil and rock samples is a fundamental and crucial task, as the quality of the collected samples directly affects the accuracy and reliability of subsequent analytical results. Traditional soil and rock sampling equipment is typically designed for single-depth sampling, which cannot meet the need for sampling at different strata depths. This limitation results in the inability to obtain comprehensive data when analyzing soil and rock properties, thus affecting the accurate assessment of soil and rock structure, elemental distribution, and pollution levels.

[0003] Existing soil and rock sampling equipment is mostly drilling or excavation-based, which typically only collects soil and rock samples at a specific depth. It cannot differentiate between strata at different elevations. For example, some samplers may only collect shallow soil and rock samples, unable to reach deeper shallow strata; others may only sample from deeper soil layers, failing to obtain information about shallow soil and rock layers. This single-depth sampling method limits the depth and breadth of soil and rock analysis, making it difficult for researchers to obtain continuous soil and rock profile data, thus hindering the accurate analysis of variations and coupling relationships between strata.

[0004] Therefore, developing a device suitable for shallow soil and rock sampling at different elevations has significant practical application value. Utility Model Content

[0005] The purpose of this invention is to provide a shallow sampler that can efficiently sample soil and rock at different elevations, thereby obtaining continuous samples of soil and rock profiles more accurately and providing richer and more accurate data support for soil and rock analysis.

[0009] The sampling structure comprises a top mounting shell mounted at the bottom of the push rod motor stroke rod, a bottom collecting shell threadedly connected at the bottom of the top mounting shell, and the feeding port is arranged at the bottom of the bottom collecting shell.

[0010] The lower part of the bottom collecting shell is provided with an inclined surface, and the feeding port is arranged on the inclined surface and at a position close to the top end.

[0011] The rotating plate is rotatably connected in the mounting plate, the second penetrating groove is arranged in the rotating plate and corresponds to the first penetrating groove in number and position, the driving motor is mounted at the top of the mounting plate, and the output end of the driving motor penetrates through the mounting plate and is connected with the rotating plate.

[0012] The diameter of the second penetrating groove is smaller than that of the first penetrating groove, and the diameter of the second penetrating groove is greater than that of the bottom collecting shell and the top mounting shell.

[0013] The outer side of the down drill block is provided with a spiral guide plate.

[0014] The technical effects achieved by the utility model are as follows:

[0023] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0024] like Figures 1-5 As shown, a shallow sampler includes a mounting frame 1. A threaded rod 2 is threadedly connected to the inside of the mounting frame 1. A lower drill block 3 is fixed to the bottom of the threaded rod 2. Further, a spiral guide plate 13 is provided on the outer side of the lower drill block 3. The spiral guide plate 13 is provided so that when the lower drill block 3 moves, it can drive the spiral guide plate 13 to rotate with the lower drill block 3. The rotation of the spiral guide plate 13 will guide the sampler to the upper layer of the lower drill block 3, avoiding sudden jamming at the position of the lower drill block 3. An installation plate 4 is installed on the bottom of the inner side of the lower drill block 3. Multiple installation slots 5 are provided inside the lower drill block 3. The installation plate 4 is provided with a first through slot 6 that is the same number and position as the installation slots 5.

[0025] Multiple push rod motors 7 are fixed in the mounting slot 5. The stroke rod of the push rod motor 7 is vertically downward and a sampling structure is installed. The bottom of the sampling structure is provided with a feed port 9. When it is necessary to remove the sampling structure to collect soil, the mounting plate 4 can be removed to facilitate the removal of the sampling structure.

[0026] When using the device, the threaded rod 2 can be rotated, and through the threaded connection between the threaded rod 2 and the mounting bracket 1, the threaded rod 2 moves downward, causing the lower drill block 3 to move downward and rotate towards the bottom until the lower drill block 3 penetrates into the shallow layer of the bottom layer. Then, by driving one of the push rod motors 7, the sampling structure on it is driven to sample the stratum at that location. Then, the threaded rod 2 is rotated again, causing the lower drill block 3 to move downward, which in turn drives the other push rod motor 7, and drives the sampling structure on it to sample, thereby enabling sampling of strata at different heights.

[0027] See attached document Figure 4, the sampling structure includes a top mounting shell 14 mounted at the bottom of the stroke rod of the push rod motor 7, the bottom of the top mounting shell 14 is threadedly connected with a bottom collecting shell 8, and an inlet 9 is arranged at the bottom of the bottom collecting shell 8; when sampling, the soil enters the bottom collecting shell 8 and the top mounting shell 14 through the inlet 9; after the sampling structure is moved out of the soil, the top mounting shell 14 and the bottom collecting shell 8 can be separated through the threaded connection of the top mounting shell 14 and the bottom collecting shell 8, and then the soil in the sampling structure can be taken out.

[0028] Referring to the accompanying drawings Figure 4 The lower part of the bottom collecting shell 8 is provided with a slope 10, and the inlet 9 is arranged on the slope 10 and close to the top end; through the arrangement of the inlet 9, when the sampling structure moves downward, the soil can be suddenly moved to the inlet 9 through the slope 10 and then falls to the bottom inside the bottom collecting shell 8 after suddenly entering the bottom collecting shell 8, without falling from the inlet 9.

[0029] Referring to the accompanying drawings Figure 5 The mounting plate 4 is rotationally connected with a rotating piece 15, the rotating piece 15 is provided with second through grooves 12 which are the same in number and position as the first through grooves 6, further, the diameters of the second through grooves 12 are smaller than the diameters of the first through grooves 6, and the diameters of the second through grooves 12 are larger than the diameters of the bottom collecting shell 8 and the top mounting shell 14; when the second through grooves 12 are rotationally aligned with the first through grooves 6, the diameters of the second through grooves 12 are smaller than the diameters of the first through grooves 6, so as to avoid the soil entering the mounting plate 4 from the gaps between the first through grooves 6 and the second through grooves 12, and the diameters of the second through grooves 12 are larger than the diameters of the top mounting shell 14 and the bottom collecting shell 8 in the sampling structure, so that the top mounting shell 14 and the bottom collecting shell 8 can pass through the second through grooves 12 to reach the soil below; the top of the mounting plate 4 is provided with a driving motor 11, and the output end of the driving motor 11 passes through the mounting plate 4 and is connected with the rotating piece 15; when the drill block 3 moves downward, the driving motor 11 drives and rotates the rotating piece 15, and rotates the second through grooves 12 to be not aligned with the first through grooves 6; after the drill block 3 moves to a specified position, the driving motor 11 is driven again, so as to rotate the rotating piece 15, and rotate the second through grooves 12 on the rotating piece 15 to be aligned with the first through grooves 6, so that the push rod motor 7 can drive the sampling structure to extend into the soil, and then the soil can be sampled; in order to facilitate observation, the rotating piece 15 in the accompanying drawings Figure 5 is a cutting effect, and actually, the rotating piece 15 is a complete circle.

[0030] The above merely describes preferred embodiments of the present application, and it should be noted that, for those skilled in the art, without departing from the principles of the present application, a number of improvements and refinements can be made, and these improvements and refinements should also be considered as the protection scope of the present application. Structures, devices and operation methods not specifically described and explained in the present application are implemented according to conventional means in the art, unless otherwise specified and limited.
