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

[0002] Utility model application CN202121399773.3 discloses a soil sampling device for soil remediation. The driven bevel gear rotates on a horizontal plane through the meshing of a motor and two bevel gears, and a threaded connection drives the threaded rod to move rapidly up and down, thereby controlling the high-speed lifting and lowering of the sampling mechanism to complete the sampling work.

[0003] The aforementioned device allows soil to enter the collection tube through the feed inlet. During the descent of the collection tube, before reaching the required depth, soil will enter the collection tube from the feed inlet. Soil from different depths will enter the collection tube, and soil from different depths will easily mix together, reducing the sampling accuracy. Utility Model Content

[0004] The purpose of this invention is to solve the above-mentioned problems by designing a soil sampler for soil sampling.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A soil sampler for soil sampling, comprising: Sampling casing; A control host is provided, and a cable is provided between the control host and the sampling shell. One end of the cable is fixedly connected to the control host, and the other end of the cable is fixedly connected to the sampling shell. Sampling bottles are used to hold soil samples; A sampling component for collecting soil samples is mounted on a sampling housing so that the sampling component moves with the sampling housing.

[0006] Furthermore, the sampling assembly includes a helical blade, a multi-stage power push rod is fixedly installed on one side of the sampling housing, an arc-shaped top plate is installed on the telescopic end of the multi-stage power push rod, a feed inlet is connected to the other side of the sampling housing, an arc-shaped guide plate is fixedly connected to the feed inlet, the helical blade is rotatably connected to the sampling housing, the helical blade is located above the arc-shaped guide plate, a fixed partition plate is installed inside the sampling housing, a drive motor is installed on the fixed partition plate, and the output end of the drive motor is fixedly connected to one end of the helical blade.

[0007] Furthermore, the sampling assembly also includes guide slides, two of which are fixedly installed inside the sampling housing. A guide slider is slidably connected to the guide slide, and a movable slide is slidably connected to the side wall of the sampling housing. The movable slide penetrates the sampling housing, with one end of the movable slide extending into the sampling housing and fixedly connected to the guide slider. A top block is installed at the other end of the movable slide, and a telescopic spring is fitted on the movable slide.

[0008] Furthermore, an inverted conical hopper is installed on the inner wall of the sampling shell, and the discharge end of the inverted conical hopper is provided with an external thread. The sampling bottle is threadedly connected to the inverted conical hopper through the external thread, and the sampling shell is connected to a box cover through a hinge.

[0009] It facilitates the assembly and disassembly of the sampling bottles, improving sampling efficiency.

[0010] Furthermore, the end of the arc-shaped guide plate away from the feed inlet has a pointed bevel.

[0011] Furthermore, the cable has a rubber outer layer with graduation lines on it, and the connection between the cable and the sampling shell is covered with silicone rubber.

[0012] The rubber outer layer increases the cable's lifespan and abrasion resistance. The depth of the sampling shell can be directly observed through the scale lines, eliminating the need for additional measuring tools and repeated adjustments.

[0013] Compared with the existing technology, the present technical solution has the following beneficial effects: 1. The sampling shell is lowered into the borehole via a cable, and the depth of the sampling shell can be controlled. No additional measuring tools or repeated adjustments are required, which is convenient and labor-saving. The soil is transported by spiral blades and arc-shaped guide plates, which facilitates soil sampling. Soil samples from different depths can be collected, avoiding mixing of soil from different depths and improving sampling accuracy. 2. The sliding rod is reset by the force of the telescopic spring, pushing the spiral blades and arc-shaped guide plate out of the soil, which facilitates the retraction of the sampling shell and prevents the spiral blades and arc-shaped guide plate from getting stuck in the soil, thus improving work efficiency.

[0021] In the description of this utility model, it should be understood that the terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, in the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0022] This utility model provides, for example Figure 1-5 A soil sampler for soil sampling, as shown, includes: Sampling shell 1; A control host 2 is provided with a cable 3 between the control host 2 and the sampling housing 1. One end of the cable 3 is fixedly connected to the control host 2 and the other end of the cable 3 is fixedly connected to the sampling housing 1. Sampling bottle 4, used to hold soil samples; Sampling component 5 is used to collect soil. Sampling component 5 is mounted on sampling shell 1 so that sampling component 5 moves with sampling shell 1.

[0023] During sampling, a hole is first drilled in the ground using a drilling machine. After drilling is completed, the drilling machine is removed, and the sampling shell 1 is slowly lowered into the hole via cable 3. The depth of the sampling shell 1 can be controlled via cable 3. No additional measuring tools or repeated adjustments are required, making it convenient and labor-saving. Once the target depth is reached, the sampling component 5 is operated by the control host 2 to transport the soil from the inner wall of the hole and store it in the sampling bottle 4. This facilitates soil sampling and allows for the collection of soil samples from different depths, preventing soil from different depths from mixing together and improving sampling accuracy.

[0024] Refer to the instruction manual appendix Figure 1 Instruction manual attached Figure 2 Included with instruction manual Figure 4 The sampling assembly 5 includes a spiral blade 6. A multi-stage power push rod 7 is fixedly installed on one side of the sampling housing 1. An arc-shaped top plate 8 is installed on the telescopic end of the multi-stage power push rod 7. A feed inlet 9 is connected to the other side of the sampling housing 1. An arc-shaped guide plate 10 is fixedly connected to the feed inlet 9. The spiral blade 6 is rotatably connected to the sampling housing 1. The spiral blade 6 is located above the arc-shaped guide plate 10. A fixed partition plate 11 is installed inside the sampling housing 1. A drive motor 12 is installed on the fixed partition plate 11. The output end of the drive motor 12 is fixedly connected to one end of the spiral blade 6.

[0025] After the sampling shell 1 reaches the target depth, the multi-stage power push rod 7 starts working. The telescopic end of the multi-stage power push rod 7 extends and drives the arc-shaped top plate 8 to move. The arc-shaped top plate 8 contacts the inner wall of the borehole. The telescopic end of the multi-stage power push rod 7 continues to extend and push the sampling shell 1 to move in the opposite direction to the arc-shaped top plate 8, so that the arc-shaped guide plate 10 inserts into the side wall of the borehole. The drive motor 12 starts working. The output end of the drive motor 12 drives the spiral blade 6 to rotate. The rotating spiral blade 6 drills holes in the inner wall of the borehole. The spiral blade 6 and the arc-shaped guide plate 10 are inserted into the soil. The soil falls on the arc-shaped guide plate 10. The spiral blade 6 transports the soil on the arc-shaped guide plate 10. The soil enters the interior of the sampling shell 1 through the feed port 9, which facilitates soil sampling. Soil samples from different depths can be collected, avoiding mixing of soil from different depths and improving sampling accuracy.

[0026] Refer to the instruction manual appendix Figure 2 The sampling assembly 5 also includes guide slide rods 13. Two guide slide rods 13 are provided and fixedly installed inside the sampling housing 1. A guide slider 14 is slidably connected to the guide slide rod 13. A movable slide rod 15 is slidably connected to the side wall of the sampling housing 1. The movable slide rod 15 passes through the sampling housing 1. One end of the movable slide rod 15 extends into the sampling housing 1 and is fixedly connected to the guide slider 14. A top block 16 is installed at the other end of the movable slide rod 15. A telescopic spring 17 is fitted on the movable slide rod 15.

[0027] When the spiral blade 6 and the arc-shaped guide plate 10 are inserted into the soil, the top block 16 fits against the inner wall of the borehole. The top block 16 and the movable slide rod 15 slide under pressure. The top block 16 applies pressure to the telescopic spring 17, which deforms and contracts under pressure. The movable slide rod 15 slides, driving the guide slider 14 to slide along the guide slide rod 13. The guide slide rod 15 is guided by the guide slide rod 13 and the guide slider 14 to prevent the movable slide rod 15 from bending and deforming. After sampling is completed, the multi-stage power push rod 7 is reset. Under the elastic force of the telescopic spring 17, the movable slide rod 15 is reset, pushing the spiral blade 6 and the arc-shaped guide plate 10 out of the soil. This facilitates the retraction of the sampling shell 1 and prevents the spiral blade 6 and the arc-shaped guide plate 10 from getting stuck in the soil, thus improving work efficiency.

[0028] Refer to the instruction manual appendix Figure 1 Included with instruction manual Figure 3 The inner wall of the sampling shell 1 is equipped with an inverted conical hopper 18. The discharge end of the inverted conical hopper 18 is provided with an external thread. The sampling bottle 4 is threadedly connected to the inverted conical hopper 18 through the external thread. The sampling shell 1 is connected to a box cover 19 through a hinge.

[0029] After the soil enters the sampling shell 1, it is guided by the inverted conical hopper 18 and enters the sampling bottle 4. The soil is collected through the sampling bottle 4. The sampling bottle 4 is threadedly connected to the inverted conical hopper 18, which facilitates the assembly and disassembly of the sampling bottle 4 and improves the sampling efficiency.

[0030] Refer to the instruction manual appendix Figure 3 Included with instruction manual Figure 5 The cable 3 has a rubber outer layer 20, and the rubber outer layer 20 has scale lines 21. The connection between the cable 3 and the sampling shell 1 is covered by silicone rubber 22.

[0031] The rubber outer layer 20 improves the service life and wear resistance of the cable 3. The depth of the sampling housing 1 can be directly observed through the scale line 21 without the need for additional measuring tools or repeated adjustments. The silicone rubber 22 provides shock absorption and cushioning at the connection between the cable 3 and the sampling housing 1.

[0032] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
