The utility model has a simple structure, convenient operation, and small excavation workload, which can improve the efficiency of topsoil thickness survey and reduce the damage to the soil during the topsoil thickness survey.

[0004] To achieve the above purpose, the utility model is implemented through the following technical solutions:

[0005] A portable topsoil thickness survey and measuring instrument for topsoil survey comprises a rotating mechanism, a transparent measuring tube and a circular cutting assembly. The top of the transparent measuring tube is coaxially fixed with the driving end of the rotating mechanism, the bottom of the transparent measuring tube is coaxially fixed with the circular cutting assembly, a measuring scale is engraved on the transparent measuring tube, and the rotating mechanism is used to drive the transparent measuring tube to rotate axially, thereby driving the circular cutting assembly to perform circumferential cutting.

[0006] Preferably, an directional cylinder is fixedly mounted on the top of the transparent measuring cylinder, a screw is fixed on the top of the directional cylinder, and the screw is fixed to a nut on the driving end of the rotating mechanism.

[0007] Preferably, the rotating mechanism adopts an electric wrench.

[0008] Preferably, the transparent measuring cylinder is made of transparent acrylic material.

[0009] Preferably, the circular cutting assembly comprises a circular cutter and a connecting sleeve, the circular cutter is coaxially fixed to the bottom of the connecting sleeve, and the connecting sleeve is fixed to the bottom of the transparent measuring tube.

[0010] Preferably, the diameter of the ring cutter decreases gradually along the direction of excavating the soil.

[0011] Preferably, the ring cutter is made of stainless steel.

[0012] Compared with the prior art, the utility model has the following significant advantages:

[0013] The utility model has a simple structure and is easy to operate. Only one worker needs to hold and start the electric wrench to complete the excavation survey of the topsoil, avoiding the traditional method of using a shovel to excavate the soil profile to conduct a survey of the topsoil thickness, which can reduce the land excavation area and reduce the workload of the investigators. At the same time, the scale on the transparent measuring tube can be used to conveniently and quickly read the thickness of the topsoil layer. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] In order to enable those skilled in the art to better understand the technical solution of the utility model, the preferred implementation scheme of the utility model is described below in conjunction with specific embodiments. However, it should be understood that the drawings are only used for illustrative purposes and cannot be understood as a limitation on this patent. In order to better illustrate this embodiment, some parts of the drawings may be omitted, enlarged or reduced, and do not represent the size of the actual product. For those skilled in the art, the omission of some well-known structures and their descriptions in the drawings is understandable. The positional relationship described in the drawings is only used for illustrative purposes and cannot be understood as a limitation on this patent.

[0018] like Figure 1-2 As shown, the utility model is a portable topsoil thickness survey and measuring instrument for topsoil survey, which is in the shape of a long strip and includes a rotating mechanism 1, a transparent measuring tube 2 and a ring cutting assembly 3. The top of the transparent measuring tube 2 is coaxially fixed with the driving end of the rotating mechanism 1, and the bottom of the transparent measuring tube 2 is coaxially fixed with the ring cutting assembly 3. The transparent measuring tube 2 is engraved with a measuring scale, and the rotating mechanism 1 is used to drive the transparent measuring tube 2 to rotate axially, thereby driving the ring cutting assembly 3 to perform circumferential cutting.

[0019] In some examples, the top of the transparent measuring cylinder 2 is fixed with an directional cylinder 4, the top of the directional cylinder 4 is fixed with a screw 5, and the screw 5 is fixed with a nut 6 on the driving end of the rotating mechanism 1. Among them, the diameter of the directional cylinder 4 is larger than the diameter of the transparent measuring cylinder 2, and the connection method between the directional cylinder 4 and the transparent measuring cylinder 2 can be selected by conventional methods in the art, and can be bonded or other fixing methods.

[0020] In some examples, the rotating mechanism 1 uses an electric wrench, which can enable mechanical operation during the topsoil survey, avoiding the traditional form of using a shovel to dig the soil profile for topsoil thickness survey, which can reduce the land excavation area and reduce the workload of the investigators. The electric wrench is selected from conventional options in the field, and can drive the transparent measuring tube 2 to rotate.

[0021] In some examples, the transparent measuring tube 2 is made of transparent acrylic material, which can quickly and easily read the thickness of the topsoil layer.

[0022] In some examples, the annular cutting assembly 3 includes an annular cutter 31 and a connecting sleeve 32 , the annular cutter 31 is coaxially fixed to the bottom of the connecting sleeve 32 , and the connecting sleeve 32 is fixed to the bottom of the transparent measuring tube 2 .

[0023] In some examples, the diameter of the ring cutter 31 decreases gradually along the direction of excavating the soil, which can speed up the excavation speed and reduce the area of ​​soil damage.

[0024] In some examples, the ring blade 31 is made of stainless steel, which can improve the durability of the ring blade 31 and prevent it from being corroded by soil.

[0025] The method of using the measuring instrument is as follows: when using it, the stainless steel ring knife 31 can be placed on the land to be investigated, the electric wrench can be turned on, and the ring knife 31 can be pushed deeply into the soil when the electric wrench is rotated. At the same time, the soil measurement situation can be observed in real time in the transparent measuring tube 2 until the soil fills the entire transparent measuring tube 2. By observing the soil characteristics in the transparent measuring tube 2, the thickness of the topsoil can be read.
