Description

Technical Field

[0001] The utility model relates to a surface soil stripping sampling device, belonging to the technical field of soil body sampling. Background Art

[0002] Topsoil is also called cultivated soil. Topsoil stripping is the reuse of topsoil stripping, which refers to the technology of moving the topsoil of about 30 cm thick on the land occupied by the construction to a fixed site for storage, and then moving it to the abandoned land for reclamation. Before the start of the production and construction project, the cultivated soil within the scope of the project is stripped and used for land reclamation or vegetation restoration in the later stage of the project. It is an important measure to protect high-quality arable land and vegetation resources and reduce soil erosion.

[0003] Topsoil stripping can effectively protect the surface mature soil resources from loss and waste, reduce the additional capital investment generated by external soil transfer during land reclamation, ensure the land area for construction and use, and stabilize the arable land area. In addition, the stripped topsoil is used for land reclamation, the soil fertility is sufficient, and the crop yield is high; it can also reduce the cost and time of maturation of external soil transfer for land reclamation, and significantly increase efficiency. Before topsoil stripping, the area of ​​topsoil to be stripped is usually mapped, and detection points are set up for sampling and analysis. The topsoil can be tested by professional institutions to maximize the use of land resources. With the continuous refinement of topsoil stripping, the sampling and testing link has become increasingly important. Through accurate sampling and testing, it is convenient to set the stripping standards according to indicators such as soil fertility and pollution level, so that more topsoil resources are obtained and the quality is guaranteed, which is conducive to shortening the transformation period and farming, so as to make the best use of them.

[0004] At present, some surface soil stripping and sampling are carried out with a shovel, which is not professional and convenient enough. There are also professional sampling equipment, which is generally a single-pole structure with a sampling cylinder at one end and an operating handle at the other end. When sampling, the operating handle is rotated, and the sampling cylinder can drill down into the soil layer for sampling. When sampling, the existing surface soil stripping sampling equipment has a small bottom area of ​​the sampling cylinder, so it is easy to cause the entire device to tilt during the downward pressure sampling process, which may lead to inaccurate samples, and even cause the sampling equipment to injure the user due to excessive force when tilting. In addition, the existing sampling equipment is usually a fixed integrated structure, which is not convenient for storage and carrying. Sometimes it is necessary to carry multiple sampling devices with different excavation end structures to sample different soil sampling points, which further deepens the inconvenience of the user.

[0027] Example 1

[0028] like Figure 1-Figure 5 As shown: A surface soil stripping sampling device includes a sampling rod 1 and an operating handle 2 and a sampling barrel 3 respectively arranged at both ends of the sampling rod 1, and the operating handle 2 is symmetrically arranged along the sampling rod 1. The sampling device disclosed in this embodiment also includes a limiting plate 4, and the operating handle 2 and the sampling barrel 3 are respectively detachably connected to the sampling rod 1, which is convenient for storage and carrying. The limiting plate 4 includes an integrally formed first limiting portion 5 and a second limiting portion 6, and the second limiting portion 6 extends outward from one side of the first limiting portion 5. The first limiting portion 5 is provided with a limiting hole 7, and the sampling barrel 3 is inserted into the limiting hole 7.

[0029] When using this embodiment, the limiting plate 4 is placed at the detection point to be sampled, and then the operator steps on the second limiting portion 6 with one foot, and holds the operating handle 2 to insert the sampling tube 3 along the limiting hole 7 set on the first limiting portion 5, and penetrates into the soil to take samples. The drilling is reliable and not skewed; and the split design is convenient for storage and carrying, and it is also convenient to equip different sampling tubes 3 and use different sampling tubes 3 according to the actual situation of the sampling point, which is flexible to use.

[0030] Example 2

[0031] This embodiment is based on the embodiment 1, and provides a specific structure in which the operating handle 2 and the sampling tube 3 are detachably connected to the sampling rod 1: the surface soil stripping sampling device described in this embodiment, the sampling rod 1 is a cylindrical rod, and the two ends of the sampling rod 1 are respectively provided with connectors 8, and the connection between the connector 8 and the rod body of the sampling rod 1 is provided with a step, and the operating handle 2 and the sampling tube 3 are respectively provided with a first connecting tube 9 and a second connecting tube 10 for accommodating the connecting head 8, and the connecting head 8 is a polygonal column, preferably a hexagonal column, and the inner cavity of the first connecting tube 9 and the second connecting tube 10 is a corresponding hexagonal cavity. After the connecting head 8 is connected to the first connecting tube 9 or the second connecting tube 10, the first connecting tube 9 or the second connecting tube 10 abuts on the step at the connection between the connecting head 8 and the rod body of the sampling rod 1, and the outer diameter of the first connecting tube 9 and the second connecting tube 10 is the same as the outer diameter of the sampling rod 1. The operating handle 2 and the sampling tube 3 are connected by means of the hexagonal connecting head 8, and the connection is more stable and reliable during the rotation and pressing process.

[0032] When in use, the sampling tube 3 is inserted into the limiting hole 7 provided on the first limiting portion 5, and then the sampling rod 1 and the operating handle 2 are sequentially assembled on the sampling tube 3, and then the operating handle 2 is held and rotated and pressed down, so that the sampling tube 3 is driven by the sampling rod 1 to rotate and press down to perform sampling. After the sampling is completed, the operating handle 2 and the sampling rod 1 are removed, and the sampling tube 3 is pulled out through the second connecting tube 10 on the sampling tube 3.

[0033] Example 3

[0034] This embodiment provides a more detailed structure in which the operating handle 2 and the sampling tube 3 are detachably connected to the sampling rod 1, based on the embodiment 2, specifically:

[0035] The surface soil stripping sampling device described in this embodiment also includes a connecting ring 11, in which an internal thread is arranged, and the two ends of the sampling rod 1, the outer surfaces of the first connecting tube 9 and the second connecting tube 10 are respectively provided with external threads, and the first connecting tube 9 and the second connecting tube 10 are respectively connected to the two ends of the sampling rod 1 through the connecting ring 11, that is, the operating handle 2 and the sampling tube 3 are respectively connected to the sampling rod 1 through the connecting ring 11. The sampling tube 3, the sampling rod 1 and the operating handle 2 are connected as a whole, which is more convenient for sampling. The operating handle 2 and the sampling tube 3 are connected by means of the hexagonal prism connector 8, and then the three are connected as a whole by the connecting ring 11. During the rotation and pressing process, the connection is more stable and reliable. If the threaded connection is directly used without the hexagonal prism connector 8 and the hexagonal cavity connecting tube, during the rotation and pressing process of the sampling device, the thread of the connection is easy to wear and easy to be loosened due to misoperation, such as reverse rotation, and the connection is unreliable.

[0036] The two ends of the sampling rod 1 are also provided with locking rings 18 respectively. When the connecting ring 11 is not used to connect the sampling tube 3 or the operating handle 2, the connecting ring 11 is rotated to be tightly against the locking ring 18, so that the connecting ring 11 is stored on the sampling rod 1 for the next use.

[0037] Example 4

[0038] This embodiment provides an optimized design of the structure configuration of a sampling device based on the embodiment 3, specifically:

[0039] The surface soil stripping sampling device described in this embodiment is equipped with the sampling tube 3 including at least three types, such as Figure 3 As shown, there are respectively a bevel end sampling tube 3, a blade end sampling tube 3 and a sawtooth end sampling tube 3, the excavation capabilities of the three increase successively. The sampling tube 3 with which excavation capability can be selected according to the situation of the sampling point, and a more powerful spiral rod sampling head can also be equipped (not shown in the figure).

[0040] Example 5

[0041] This embodiment is based on the embodiment 4, and optimizes the structure of the sampling device limit plate 4, specifically:

[0042] like Figure 5 As shown: the surface soil stripping sampling device described in this embodiment has a limiting ring 12 disposed on the lower side of the first limiting portion 5 of the limiting plate 4. The limiting ring 12 protrudes from the lower side of the first limiting portion 5 and is directly opposite to the limiting hole 7, which is equivalent to extending the depth of the limiting hole 7, increasing the guiding range and ability of the first limiting portion 5 to the sampling tube 3, and preventing the sampling tube 3 from tilting or even falling during the sampling process. When in use, the limiting ring 12 is first nailed into the ground, and the first limiting portion 5 and the second limiting portion 6 are attached to the ground.

[0043] The lower end of the limiting ring 12 in this embodiment is provided with dense limiting teeth 13, and the limiting teeth 13 facilitate the limiting ring 12 to be nailed into the ground.

[0044] Example 6

[0045] This embodiment is based on the embodiment 5, and further optimizes the structure of the sampling device limit plate 4, specifically:

[0046] In the surface soil stripping sampling device described in this embodiment, a plurality of obstruction bars 14 are respectively arranged on the upper and lower sides of the second limiting portion 6 of the limiting plate 4 to enhance the deformation resistance of the second limiting portion 6. The obstruction bars 14 are transversely connected between the second limiting portion 6 and the end of the first limiting portion 5 close to the second limiting portion 6 to enhance the structural strength of the connection between the second limiting portion 6 and the first limiting portion 5. At the same time, through the arrangement of the obstruction bars 14, when the user steps on the second limiting portion 6, a stronger resistance can be provided to prevent the limiting plate 4 from loosening or even detaching from the soil during the process of screwing in or taking out the sampling tube 3.

[0047] In this embodiment, the free end of the second limiting portion 6 is also provided with an upward clamping plate 15. When the user steps on the second limiting portion 6, the outer side of the foot fits against the inner side of the clamping plate 15. If the sampling plate has a tendency to rotate, the clamping plate 15 will be clamped with the user's foot, thereby preventing the sampling plate from rotating and providing a better guiding effect. After sampling, the limiting plate 4 can also be quickly removed from the soil through the clamping plate 15.

[0048] Example 7

[0049] This embodiment is based on the embodiment 6, and further optimizes the structure of the sampling device limit plate 4, specifically:

[0050] The topsoil stripping sampling device described in this embodiment has an internal thread arranged inside the limiting ring 12, and the upper part of the sampling tube 3 is provided with an external thread matching the internal thread, and the external thread protrudes from the outer surface of the sampling tube 3. When sampling, it is usually difficult to screw the bottom section of the soil into or out of the sampling tube 3. The setting of the thread facilitates the screwing of the sampling tube 3 into and out of the bottom section of the soil.

[0051] In this embodiment, a material extraction groove 16 is provided on one side of the sampling tube 3 to facilitate the screwing of the sampling tube 3 and the extraction of materials from the sampling tube 3. Protective gloves 17 are provided at both ends of the operating handle 2 to protect the operator's hands.

[0052] When using the utility model: place the limit plate 4 at the detection point, then select the appropriate type of sampling tube 3, then plug the connection tubes of the sampling tube 3 and the operating handle 2 into the connectors 8 at both ends of the sampling rod 1, and then unscrew the connection rings 11 at both ends of the sampling rod 1, so that the connection rings 11 connect the sampling rod 1 and the sampling tube 3, and the sampling rod 1 and the operating handle 2. After the assembly is completed, hold the operating handle 2, insert the sampling tube 3 along the limit hole 7 of the limit plate 4, and continuously rotate and press down until the target depth, then hold the operating handle 2 to take out the sampling tube 3. During the whole process, the operator steps on the second limit part 6 of the limit plate 4 to prevent it from rotating or falling out. Take out the sample in the sampling tube 3 and sample the next detection point. During the process, if the soil structure at the detection point changes, such as becoming hard, the type of sampling tube 3 can be replaced, such as a serrated end sampling tube 3, and then sampling can be carried out. After the sampling is completed, the limit plate 4 is retracted, and the connecting rings 11 at both ends of the sampling rod 1 are rotated until they are tightly against the locking ring 18, so that the sampling tube 3 and the operating rod can be separated from the sampling rod 1, and then stored.

[0053] In addition, in the description of the present utility model, unless otherwise specified, if the terms "multiple", "multiple roots", "multiple groups" are used, they mean two or more than two, and "several", "several roots", "several groups" mean one or more than one. In the description of the present utility model, it should be noted that if the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inside", "outside" and the like are used to indicate the orientation or position relationship based on the orientation or position relationship shown in the accompanying drawings, it is only for the convenience of describing the present utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present utility model.
