A sampling depth scale 6 is arranged between the demolding handle 4 and the main handle 1, which can be referred to by a user when the sampling depth is reached.

[0024] In use, the demolding assembly is first moved to the lower end of the beveled tip sleeve by the demolding handle, then the lower end of the beveled tip sleeve is inserted into the soil to be sampled by holding the main handle, then the whole sampler is uprighted, the hammering assembly is held, and the beveled tip sleeve is completely hammered into the soil in a continuous reciprocating hammering manner until the sampling depth scale reaches a predetermined value, then the main handle is moved to take out the beveled tip sleeve from the soil. When the sample is removed, the sample is pushed out of the beveled tip sleeve by the demolding handle, and then the sample is removed, i.e. the sampling is completed. The demolding handle and the demolding assembly are arranged in the present embodiment, complete demolding after sampling is realized, the integrity of the sample is maintained as much as possible, the sampler has reliable structure, is convenient to operate, and has complete sampling, which can reduce the labor intensity of inserting into soil during sampling.

[0025] In the embodiment 2, on the basis of the embodiment 1, the main handle 1 comprises a vertical pipe 11, the upper end of the vertical pipe 11 is transversely provided with a handle 12, the sample removal handle 4 is slidably arranged at the axis of the vertical pipe 11, and the lower end of the vertical pipe 11 is connected with the bevel sleeve 2. In the embodiment, the handle 12 is arranged in a T shape with the vertical pipe, so that the bevel sleeve is held by the handles 12 on both sides, and when the sample is removed, the bevel sleeve can be tilted and displaced by pressing the handle obliquely downward, so that the lower end of the sample is separated from the soil, the sampler can carry the sample as a whole, and the operation is more stable and convenient.

[0026] In the embodiment, the hammering mechanism 5 comprises a hammering disc 13 fixedly arranged on the vertical pipe 11, and a hammer 14 slidably arranged on the vertical pipe 11 above the hammering disc 13 and matched with the hammering disc 13. When sampling, after the lower end of the bevel sleeve is slightly inserted into the soil and is upright, the hammer 14 is held and vertically reciprocatingly slides along the vertical pipe to hammer the hammering disc with the lower end of the hammer, the hammering disc drives the vertical pipe and the bevel sleeve to synchronously move downward, and the bevel sleeve is inserted into the soil, and the corresponding root system and soil are cut off by the wall of the bevel sleeve. The hammering mode is convenient for insertion, the labor intensity is low compared with the pressing or treading mode, and the insertion direction and position are more accurate.

[0027] Further, the outer wall of the vertical pipe at the lower end of the hammering disc is thickened to avoid deformation when bearing the hammering.

[0028] In the embodiment 3, on the basis of the embodiment 2, as shown in Figure 3 the bevel sleeve 2 comprises a horizontal disc 21 connected with the vertical pipe, the horizontal disc 21 is connected with a cylinder 22, the lower end surface of the cylinder 22 is a bevel 23, the angle of the bevel 23 relative to the normal surface is selected as 45°, which is beneficial to insertion and maintaining the effective sampling length, and the sample removal handle 4 is connected with the sample removal assembly 3 through a through hole at the axis of the horizontal disc 21. In the embodiment, the cylinder is made of a steel plate with a thickness of 1 mm, and the lower side is sharpened to increase the pressure and be more beneficial to entering the soil and cutting off the root system.

[0029] To improve the uniformity of force transmission from the vertical pipe to the horizontal disc, a reinforcing rib 24 is arranged between the vertical pipe 11 and the horizontal disc 21, so that the force along the axis of the vertical pipe is more uniformly transmitted to the bevel sleeve during the hammering process.

[0030] In addition, to facilitate the insertion of the lower end of the bevel sleeve into the soil in the initial stage, the outer diameter of the horizontal disc is greater than that of the cylinder, so that a disc surface capable of being treading is formed, and the treading mode can be used for positioning during the initial insertion.

[0031] In the embodiment 4, on the basis of the embodiment 3, as shown in Figure 4As shown, the demolding assembly 3 comprises a main push disc 31 slidingly arranged in the cylinder 22, the demolding handle 4 comprises a core shaft 41 fixedly connected with the lower end of the main push disc 31, the upper end of the core shaft 41 penetrates through the vertical pipe 11 and is provided with a pressing plate 42 at the end. The pressing plate 42 and the handle 12 are cooperatively provided with a tension spring 43. The sampling depth scale 6 is arranged on the vertical pipe 11, and the scale value of the sampling depth scale matches the position of the lower main push disc, that is, when the main push disc is located at the uppermost position, the maximum depth state is reached, and when the main push disc is located at the edge of the lower opening of the cylinder, the lower edge of the main push disc is flush with the upper edge of the inclined surface, and the scale zero value is reached. In addition, a level 7 can be optionally arranged on the top of the pressing plate 42, and the vertical state of the entire sampler can be assisted to be determined through the level. In use, as the cylinder is inserted into the soil, the soil enters the cylinder, the main push plate is pushed to move upward, and the cylinder is taken out from the soil after reaching the maximum depth. When the sample is taken out, the pressing plate is pushed, so that the main push disc slides in the cylinder, and then the sample in the cylinder is pushed out to the outside of the cylinder.

[0032] As a further embodiment, as Figure 5 As shown, in order to improve the positioning ability and improve the integrity of the sample when being pushed out of the cylinder, and avoid breaking, a centering shaft 32 is arranged below the main push disc 31 in the embodiment. In the embodiment, the lower end of the centering shaft is a sharp end, which is convenient for insertion into the soil. A secondary push disc 33 is slidingly arranged on the centering shaft 32. The horizontal disc 21, the main push disc 31 and the secondary push disc 33 are cooperatively provided with air grooves 34. The upper part of the side wall of the cylinder is optionally provided with air grooves corresponding to the air grooves, so that air can be discharged during insertion into the soil, and air can be taken in when the sample is taken out, thereby maintaining air pressure balance.

[0033] In use, before sampling, under the action of the tension spring, the pressing plate is in a position close to the main handle, the secondary push disc is slid to one end close to the main push disc, then the sampler is righted, the centering shaft is partially or entirely inserted into the soil to be sampled by holding the pressing plate, then the lower end of the cylinder is inserted into the soil by holding the handle, then the centering shaft and the cylinder are completely inserted into the soil by hammering with the hammer, the sampling depth scale reaches the maximum value, and the whole sampler can be taken out from the soil.

[0034] When the sample is taken out, the main push disc and the secondary push disc are pushed out of the cylinder by pushing the pressing block, and then the sample is taken off the centering shaft by sliding the secondary push plate along the centering shaft.

[0035] As a further optional solution, in order to facilitate the separation of the secondary push disc and the main push disc, a support block for maintaining the gap between the main push disc and the secondary push disc is arranged on the disc surface of the secondary push disc, so that a gap can be formed, which is beneficial to moving the secondary push disc.

[0036] The above merely describes preferred embodiments of the present application and is not intended to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
