Description

Technical Field

[0001] The utility model relates to the technical field of soil detection equipment, and particularly relates to a soil core sampler. Background Art

[0002] A soil core sampler is a tool for collecting soil samples. It usually consists of an annular blade and a handle, and is used to cut and extract soil samples with a specific depth and diameter. This tool is often used in scientific research, soil analysis, and environmental monitoring, and can ensure that the collected soil samples have a certain representativeness and consistency.

[0003] When sampling soil with low water content, poor viscosity but good fluidity, the soil in the existing soil core sampler is likely to fall off, or the position of the internal soil moves when the soil core sampler is taken out, making the sampled soil sample unable to meet the sampling requirements. Summary of the Invention

[0004] The problem to be solved by the utility model is to provide a soil core sampler, which forms a closed sampling space through a sealing cover arranged outside it to prevent the sampled soil in the soil core in the sampling space from moving, improve the sampling quality, and facilitate the work of sampling personnel.

[0005] The technical solution adopted by the utility model to solve the above problems is: a soil core sampler, comprising a closed cover, a core cutter assembly, a sealing track, a sealing partition board, and a force application rod; the core cutter assembly is connected to slide up and down in the closed cover through the force application rod, an opening is arranged directly below the core cutter assembly on the closed cover, the sealing track comprises two tracks respectively arranged on two inner walls of the sealing cover, the track comprises two sliding tracks arranged symmetrically along the center line of the inner wall, the sliding track comprises a straight track section, a curved track section, and an inclined track section connected in sequence, the ends of the inclined track sections intersect, and the two inner walls are opposite to each other; the sealing partition board is slidably installed between two relatively arranged sliding tracks, the sealing partition board can be bent to adapt to the bending radian of the curved track section, the opening is used for the core cutter assembly to pass through, the sealing partition board is used to close and open the opening, and a closed space is formed in the closed cover when the opening is closed.

[0006] Preferably, the core cutter assembly comprises a plurality of mutually sleeved core cutter sleeves, wherein the uppermost core cutter sleeve is connected to the lower end of the force application rod, and a cutting edge is arranged at the bottom of the lowermost core cutter sleeve.

[0007] Preferably, the force application rod comprises a sliding rod and a handle arranged at the upper end of the sliding rod, and the lower end of the sliding rod is inserted into a movable hole on the closed cover and fixedly connected to the uppermost core cutter sleeve.

[0008] Preferably, at least two connecting protrusions are provided on the outer wall of the core cutter sleeve, and the adjacent two core cutter sleeves are locked to each other by a fastening screw passing through the adjacent connecting protrusions along the insertion direction of the core cutter sleeve.

[0009] Preferably, two limiting grooves are provided on one side of the two sliding tracks on the inner wall respectively. A shifting block is slidably connected in the limiting groove, and one end of the shifting block is fixed to the sealing partition plate.

[0010] Preferably, a limiting sliding rail is provided on the inner wall, and two limiting blocks are slidably connected to the limiting sliding rail along the direction perpendicular to the limiting groove. When the two shifting blocks respectively move to the ends of the two limiting grooves, the insertion slots of the two limiting blocks are respectively clamped with the two shifting blocks, and the two side walls of the insertion slot in the direction of the limiting groove are abutted against the shifting blocks.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] In the present utility model, when in use, the lower part of the soil core cutter sampler is placed perpendicular to the soil surface. By pressing down the handle, the sliding rod slides downward, and drives the entire core cutter assembly to insert into the soil surface through the cutting edge provided at the bottom of the lowermost core cutter sleeve, and squeezes the soil to be sampled into the core cutter sleeve. At this time, the sampled soil in the core cutter sleeve is in a flowing state; then the sealing cover is inserted downward into the soil surface, and the shifting block is moved to the end of the limiting groove, thereby driving the sealing partition plate to move along the sliding rail, passing through the straight track section and the curved track section until the end of the sealing partition plate moves to the end of the inclined track section. The ends of the two sealing partition plates are abutted against each other, and the two limiting blocks slide along the direction perpendicular to the limiting groove until the insertion slots of the two limiting blocks are respectively clamped with the two shifting blocks, and the two side walls of the insertion slot in the direction of the limiting groove are abutted against the shifting blocks, so as to fix the position of the partition plate. At this time, the sealing cover seals the entire core cutter assembly in the internal sealed space, so that the soil in the sealed space and the soil in the core cutter assembly form a static state. Finally, the entire soil core cutter sampler is taken out, achieving the effects of preventing the sampled soil in the soil core cutter in the sampling space from moving, improving the sampling quality, and facilitating the work of the sampling personnel.
