Description

Technical Field

[0001] The invention relates to the technical field of soil collection, and in particular to an adjustable soil sampling device. Background Art

[0002] Soil remediation refers to the use of physical, chemical and biological methods to transfer, absorb, degrade and transform pollutants in the soil to reduce their concentration to an acceptable level, or to transform toxic and harmful pollutants into harmless substances. The collection of soil samples is one of the most important and critical links in soil remediation work. It is a prerequisite for the correctness of the analysis results, especially for the analysis of soil after soil remediation. The collection of soil samples requires special soil sample collection devices.

[0003] Existing soil collection and sampling devices mainly collect samples by inserting a hollow tube into the soil. However, when the sampling tube is inserted into the soil, the soil has already begun to enter the tube, which makes it impossible to collect soil in a small area at a specified depth, thereby reducing the sampling efficiency and making it difficult to clean the soil in the tube later. Summary of the invention

[0004] The invention provides an adjustable soil sampling device, aiming to solve the technical problem that soil at a specified depth cannot be sampled in a small range.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] An adjustable soil sampling device comprises a mobile cart, the surface of the mobile cart is movably connected with a mobile seat through an electric push rod, the mobile seat is provided with a through cavity in the vertical direction, a collection component is inserted in the through cavity, the collection component comprises a plurality of hollow sampling tubes, the sampling tubes are threadedly connected to each other through threaded heads, notches are equidistantly provided on the outer surface of the sampling tube, a regulating component is passed through the inside of the sampling tube, the regulating component is used to control the sampling amount of the sampling tube, the regulating component is fixed to the sampling tube through a limiter component, a gear driven to rotate by a motor is arranged on the surface of the mobile cart, the gear is meshed with the notch, and the sampling tube is driven to go deep into the soil for sampling through the rotation of the gear.

[0007] Sampling at different depths can be achieved by setting up several connectable sampling tubes. The sampling tubes can be matched with the control components to carry out sampling after reaching the specified depth, which can effectively collect soil in a small area at the specified depth.

[0008] In a preferred embodiment, the regulating component includes a limit rod inserted into the sampling tube, the lower end of the limit rod is threadedly connected to a bottom rod, the lower end of the bottom rod is fixedly connected to a blocking block, the blocking block is used to block the opening at the lower end of the sampling tube, and a plurality of limit holes are equidistantly provided on the surface of the limit rod.

[0009] The lower opening of the sampling tube is blocked by a blocking block to prevent soil from entering. When soil needs to be collected, the limit rod can be pulled upward to drive the bottom rod and the blocking block upward, thereby leaving space for sampling at the lower end of the sampling tube.

[0010] In a preferred solution, the limiting assembly includes a nut threadedly connected to the upper end of the sampling tube, the outer surface of the nut is threadedly connected to a limiting bolt, and the limiting bolt corresponds to the limiting hole.

[0011] The limiting bolt is inserted into the limiting hole on the outer surface of the limiting rod, thereby fixing the position of the regulating component to prevent movement due to soil compression.

[0012] From the above, it can be seen that the adjustable soil sampling device provided by the utility model has the following technical effects.

[0013] The depth of soil collection can be adjusted by setting up several connectable sampling tubes. The sampling tube can be used to reach the specified depth before sampling. The control component can be used to effectively collect soil in a small area at the specified depth. After sampling, the limit rod of the control component can be pushed back to push out the collected soil, which effectively improves the operating efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0021] The utility model discloses an adjustable soil sampling device which is mainly used in a small-scale sampling scenario for soil with a specific depth and relatively soft soil.

[0022] Reference Figure 1 and Figure 2 , an adjustable soil sampling device, comprising a mobile cart 1, the surface of the mobile cart 1 is movably connected with a mobile seat 4 through an electric push rod 5, the mobile seat 4 is provided with a through cavity along the vertical direction, and a collection component 6 is inserted in the through cavity; the collection component 6 comprises a plurality of hollow sampling tubes 601, the sampling tubes 601 are threadedly connected to each other through threaded heads 602, and notches 603 are equidistantly provided on the outer surface of the sampling tube 601; a regulating component 9 is passed through the inside of the sampling tube 601, the regulating component 9 is used to control the sampling amount of the sampling tube 601, and the regulating component 9 is fixed to the sampling tube 601 through a limiter component; a gear 11 driven to rotate by a motor 10 is arranged on the surface of the mobile cart 1, the gear 11 is meshed with the notch 603, and the sampling tube 601 is driven to go deep into the soil for sampling through the rotation of the gear 11

[0023] In this embodiment, the sampling device is first moved to the location where sampling is required by the mobile cart 1, and then the sampling tube 601 is inserted into the through cavity of the mobile seat 4. Before sampling, the corresponding number of sampling tubes 601 can be selected for threaded docking according to the sampling depth. After the sampling tube 601 is placed, the regulating component 9 can be inserted into the sampling tube 601, and the two can be fixed by the limit component. At this time, the regulating component 9 blocks the lower end opening of the sampling tube 601 to prevent the sampling tube 601 from entering the soil when it is not inserted into the specified depth. At the beginning of sampling, The electric push rod 5 will drive the moving seat 4 and the sampling tube 601 to approach the gear 11, so that the notch 603 on the outer surface of the sampling tube 601 is meshed with the gear 11, and the motor 10 drives the gear 11 to rotate, so that the sampling tube 601 moves downward and is inserted into the soil. After reaching the specified depth, the regulating component 9 is unlocked by the limit component and moves upward along the sampling tube 601, so that the lower end of the sampling tube 601 is not blocked. As the sampling tube 601 continues to move downward, the soil will enter the sampling tube 601 and be collected, which can effectively collect the soil at the specified depth in a small range.

[0024] It is worth noting that the driving force of the gear 11 is limited, so the sampling device is not suitable for collecting soil with relatively hard soil.

[0025] Furthermore, a storage box 2 for storing the collection component 6 and the regulation component 9 is provided on the surface of the mobile cart 1, and a cover plate 3 is movably provided on the surface of the storage box 2. The storage box 2 can be used to store parts and tools of the equipment.

[0026] Reference Figure 1-Figure 4 In a preferred embodiment, the regulating component 9 includes a limiting rod 901 inserted into the sampling tube 601, the lower end of the limiting rod 901 is threadedly connected to a bottom rod 903, the lower end of the bottom rod 903 is fixedly connected to a blocking block 904, the blocking block 904 is used to block the opening at the lower end of the sampling tube 601, and a plurality of limiting holes 902 are equidistantly provided on the surface of the limiting rod 901.

[0027] In this embodiment, the bottom rod 903 located at the lower end of the sampling tube 601 blocks the lower end opening of the sampling tube 601 through the blocking block 904 to prevent soil from entering. When soil needs to be collected, the limit rod 901 can be pulled upward so that the limit rod 901 drives the bottom rod 903 and the blocking block 904 to move upward, thereby leaving space for sampling at the lower end of the sampling tube 601.

[0028] Among them, the blocking block 904 is conical with the tip facing downward, which can improve the ground-breaking effect of the device and reduce the resistance of sampling.

[0029] Reference Figure 3 and Figure 4In a preferred embodiment, the limiting assembly includes a nut 7 threadedly connected to the upper end of the sampling tube 601, and the outer surface of the nut 7 is threadedly connected to a limiting bolt 8, the limiting bolt 8 corresponds to the limiting hole 902, and is connected to the upper end of the sampling tube 601 through the nut 7, and the limiting bolt 8 is inserted into the limiting hole 902 on the outer surface of the limiting rod 901, thereby achieving the position fixation of the regulating assembly 9 to avoid movement due to squeezing by the soil.

[0030] Specifically, an extension rod is threadedly connected between the bottom rod 903 and the limiting rod 901 , and a corresponding number of extension rods can be selected according to the length of the sampling tube 601 to adjust the length of the regulating assembly 9 to ensure that the blocking block 904 is exposed at the lower end of the sampling tube 601 .

[0031] Among them, it should be noted that the spacing between the limit holes 902 is one centimeter. The thickness of the soil collected by the sampling tube 601 can be judged by observing the number of limit holes 902 exposed on the outer surface of the limit rod 901, which is convenient for personnel to perform sampling operations. After the sampling is completed, the limit rod 901 can be pushed back to squeeze out the soil inside the sampling tube 601 for easy collection.

[0032] It is easy to understand that those skilled in the art can combine, split, reorganize, etc. the embodiments of the present application to obtain other embodiments based on one or several embodiments provided in the present application, and these embodiments do not exceed the protection scope of the present application.

[0033] The present invention and its implementation methods are described schematically above, and the description is not restrictive. The embodiments shown in the embodiments are only part of the implementation methods of the present invention, and the actual structure is not limited thereto. Therefore, if a person skilled in the art is inspired by the embodiments and designs a structure and an implementation method similar to the technical solution without creativity without departing from the purpose of the invention, they should all fall within the protection scope of the present invention.
