Description

Technical Field

[0001] This utility model relates to the field of soil sampling technology, and in particular to a portable device for soil pollution detection and sampling. Background Technology

[0002] A soil sampling device is a specialized sampling equipment used in the field of soil pollution detection. Its core function is to provide accurate and efficient tool support for soil sample collection. Currently, field soil collection relies heavily on traditional tools such as shovels, sampling shovels, and soil drills. However, as the requirements for pollution detection accuracy increase, higher demands are placed on the functionality and convenience of the sampling tools.

[0003] However, existing soil sampling devices have obvious functional limitations and cannot meet the needs of soil sampling at different depths. The sampling depth is mostly fixed. To complete such multi-depth sampling operations, the sampling personnel often need to carry multiple sets of tools, which significantly increases the burden of field operations. At the same time, most soil sampling tools adopt an integrated rigid structure design that cannot be folded or disassembled. This design requires a lot of space when storing the tools, resulting in inconvenience in storage and carrying, and making it difficult to adapt to the mobile operation needs of complex terrains such as farmland and mining areas. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a portable device for soil pollution detection and collection.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a portable device for soil pollution detection and collection, comprising a collection mechanism, a foot pedal mechanism at the top of the collection mechanism, a handle at the top of the foot pedal mechanism, an upper shovel, limiting members on both sides of the top of the upper shovel, hinges on both sides of the bottom of the upper shovel, a lower shovel at the end of the hinge away from the upper shovel, and limiting holes on both sides of the bottom of the lower shovel.

[0006] In a preferred embodiment, the foot pedal mechanism includes a first connecting rod, a second connecting rod below the first connecting rod, a third connecting rod at the bottom of the second connecting rod, a foot support between the first connecting rod and the second connecting rod, and a force-bearing rod between the second connecting rod and the third connecting rod.

[0007] In one preferred embodiment, the upper shovel is fixedly connected to the limiting member by bolts, the upper shovel and the lower shovel are movably connected by hinges, and the upper shovel is fixedly connected to the connecting rod by a three-way thread.

[0008] In a preferred embodiment, the first connecting rod and the second connecting rod are fixedly connected by threads, and the second connecting rod and the third connecting rod are fixedly connected by threads.

[0009] In a preferred embodiment, the foot support is movably engaged with connecting rod one and connecting rod two, and the force-bearing rod is movably engaged with connecting rod two and connecting rod three.

[0010] In a preferred embodiment, the connecting rod is fixedly connected to the handle rod by a thread.

[0011] In a preferred embodiment, the foot support is welded and fixedly connected to the load-bearing rod.

[0012] As a preferred embodiment, the top of the foot support is provided with a diamond-shaped anti-slip texture.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] This utility model uses a hinge in the collection mechanism to connect the upper and lower shovels. With the locking structure of the limiting component and the limiting hole, the opening and closing of the lower shovel can be flexibly adjusted. When unfolded, the depth of penetration into the soil is extended, and when folded, the depth of penetration into the soil is shortened by the limiting fixation. The foot support installed between connecting rod one and connecting rod two allows the collector to adaptively adjust the angle according to their own force application habits, solving the problems of awkward force application and easy fatigue of traditional fixed foot pedals. The connecting rod one, connecting rod two, and connecting rod three are connected by threads, which can achieve quick disassembly. After disassembly, each part can be stored in a portable backpack, solving the problem of inconvenience in carrying traditional one-piece tools. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1

[0027] like Figure 1 - Figure 3 As shown, this utility model provides a technical solution: a portable device for soil pollution detection and collection, including a collection mechanism 1, a foot pedal mechanism 2 on the top of the collection mechanism 1, a handle 3 on the top of the foot pedal mechanism 2, the collection mechanism 1 including an upper shovel 11, limiting members 12 on both sides of the top of the upper shovel 11, hinges 13 on both sides of the bottom of the upper shovel 11, a lower shovel 14 on the end of the hinge 13 away from the upper shovel 11, limiting holes 15 on both sides of the bottom of the lower shovel 14, the upper shovel 11 and the limiting members 12 are fixedly connected by threads, the upper shovel 11 and the lower shovel 14 are movably connected by hinges 13, and the upper shovel 11 and the connecting rod 23 are fixedly connected by threads.

[0028] In this embodiment, the upper shovel 11 and the limiting member 12 are made of high-strength manganese steel, which enables the upper shovel 11 and the lower shovel 14 to better cut into hard soil and soil containing gravel, ensuring a smooth collection process. The bottom of the upper shovel 11 and both ends of the lower shovel 14 are provided with cutting edges, the edges of which are rounded to prevent chipping due to impact, balancing sharpness and durability. The lower shovel 14 is extended downwards via the hinge 13, increasing the depth of soil collection. When the lower shovel 14 is extended downwards via the hinge... When folded, the limiting member 12 engages with the limiting hole 15 to fix the lower shovel 14, shortening the collection depth without losing structural strength and adapting to different collection needs. The rigid connection between the upper shovel 11 and the connecting rod 21, which is fixed by bolts, ensures the stability of force transmission. This allows the downward pressure of the foot pedal mechanism 2 to act directly on the cutting edges of the upper shovel 11 and the lower shovel 14, forming a high-efficiency cutting force in combination with the structure of the cutting edges. When the device faces hard soil or gravel layers, it can still maintain a stable soil entry efficiency.

[0029] Example 2

[0030] like Figure 1 - Figure 6 As shown, the foot pedal mechanism 2 includes a connecting rod 1 21, a connecting rod 22 below the connecting rod 1 21, a connecting rod 3 23 at the bottom of the connecting rod 22, a foot support 24 between the connecting rod 1 21 and the connecting rod 22, and a force-bearing rod 25 between the connecting rod 22 and the connecting rod 3 23. The connecting rod 1 21 and the connecting rod 22 are fixedly connected by threads, the connecting rod 22 and the connecting rod 3 23 are fixedly connected by threads, the foot support 24 is movably engaged with the connecting rod 1 21 and the connecting rod 22, the force-bearing rod 25 is movably engaged with the connecting rod 22 and the connecting rod 3 23, the connecting rod 1 21 is fixedly connected to the handle bar 3 by threads, and the foot support 24 is welded and fixedly connected to the force-bearing rod 25. The top of the foot support (24) is provided with a diamond-shaped anti-slip texture.

[0031] In this embodiment, the foot support 24 installed between connecting rod 1 21 and connecting rod 22 provides a stable point of force for the data collector. The diamond-shaped anti-slip texture on the top of the foot support 24 prevents the data collector from slipping while stepping on it, ensuring safety during operation. The movable locking structure between connecting rod 1 21, connecting rod 22, and foot support 24 allows the data collector to adaptively adjust the angle according to their own force application habits, solving the problems of awkward force application and easy fatigue associated with traditional fixed foot pedals. The force-bearing rod 25, which is welded and fixed to the foot support 24, is movably locked at both ends to connecting rod 22 and connecting rod 3 23, forming a stable triangular support structure. When the data collector steps on the foot support 24, the force-bearing rod 25 transmits the vertical stepping force downward along the rod body, and the stepping force is transmitted to connecting rod 22 and connecting rod 3 23, avoiding component deformation caused by force concentration at a single connection point.

[0032] Working principle:

[0033] like Figure 1 - Figure 6 As shown, depending on the required soil depth, the opening and closing state of the lower shovel 14 is adjusted by the hinge 13 of the collection mechanism 1. If collecting shallow soil, the lower shovel 14 is folded upward. At this time, the two limiting pieces 12 on the upper shovel 11 are engaged with the two limiting holes 15 at the bottom of the lower shovel 14 to form a locking and fixing, shortening the soil penetration depth of the device. If collecting deep soil, the lower shovel 14 is pushed outward, and the lower shovel 14 is unfolded downward by the hinge 13 to extend the soil penetration depth and adapt to different collection needs.

[0034] After completing the depth adaptation adjustment, the collector holds the handle 3 and aligns it with the collection point, then steps on the foot support 24 to apply force. The diamond-shaped anti-slip texture on the top of the foot support 24 prevents the collector from slipping while stepping on it, ensuring safety during operation. The foot support 24 is connected to the connecting rod 1 21 and the connecting rod 22 by a movable latch. The angle of the foot support 24 can be adjusted to match the collector's force application habits. The stepping force is transmitted through the force-bearing rod 25 to the connecting rod 22 and the connecting rod 3 23, and finally transmitted through the connecting rod 1 21 to the upper shovel 11, so that the upper shovel 11 and the lower shovel 14 cut into the soil. After the collection is completed, the collector pulls the handle 3 to remove the device and the soil.

[0035] The collection mechanism 1, foot pedal mechanism 2, and handle bar 3 are all connected by threads, allowing for quick assembly and disassembly. After fieldwork, the connection points of the collection mechanism 1, foot pedal mechanism 2, and handle bar 3 can be unscrewed in sequence, making it easy to put into a toolbox and backpack. This solves the problem of the traditional one-piece pole taking up a lot of space when carried. The detachable structure is more suitable for field hiking and collection scenarios, significantly reducing the burden of carrying equipment and improving the flexibility of relocation operations.

[0036] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
