Technical Field
[0001] This utility model relates to the field of geological exploration technology, specifically to a paper box soil sampler that facilitates sampling. Background Technology
[0002] Soil sampling is a fundamental task in many fields such as soil research, environmental monitoring, and agricultural surveys. Collecting high-quality, representative soil samples is crucial for subsequent soil analysis. Cardboard soil samples, as a typical sampling method, are collected from bottom to top according to the soil profile. After collection, they can be used for scientific research, teaching, exhibitions, and popular science.
[0003] Most existing cardboard soil samplers use traditional manual sampling methods, requiring manual insertion of the sampler into the soil to extract the sample. However, an exploration operation often requires carrying more than one type of sampler. Existing cardboard soil samplers are generally large in size, lack storage capacity, and are inconvenient to carry. In addition, their irregular shape often takes up more space, making it inconvenient for operators to conduct exploration and sampling operations outdoors for extended periods. Utility Model Content

The bucket has a bucket-shaped structure with openings at the front and top. The top of the bucket back plate has an clearance notch, and a horizontal axis is provided in the clearance notch. A folding handle that can rotate 180 degrees with the horizontal axis is connected to the horizontal axis.
[0005] In a preferred embodiment, the folding handle is a hollow cylindrical structure, a tension spring mounting seat perpendicular to the horizontal axis is fixedly connected to the horizontal axis, a tension spring is installed on the tension spring mounting seat, the folding handle is gap-fitted outside the tension spring mounting seat, and the other end of the tension spring is connected to the inner wall of the folding handle.
[0006] In a preferred embodiment, the end face of the folding handle near the back plate of the bucket is provided with a crossbar perpendicular to the folding handle, and the two sides of the back plate of the bucket are provided with limiting grooves that are embedded and engaged with the crossbar. When the folding handle is rotated to fit against the back plate of the bucket, the crossbar falls into the limiting groove.
[0007] In a preferred embodiment, the end of the folding handle furthest from the bucket backplate is threaded with a spiral ring, which is connected to a tension spring.
[0008] In a preferred embodiment, the front end of the bucket side plate is an arc-shaped cut, and the radius of the arc-shaped cut is the height of the bucket side plate.
[0009] In a preferred embodiment, the bottom, sides, and back of the bucket are provided with ventilation holes to prevent negative pressure from forming due to poor ventilation inside the bucket.
[0010] Compared with the prior art, this utility model provides a convenient cardboard box soil sampler with the following advantages.
[0011] The folding handle design facilitates storage and carrying, saving space and making it easy to store and transport. Furthermore, the tension spring and self-locking structure enhance the connection stability between the folding handle and the bucket backplate, improving comfort and safety during use. The curved cut at the front of the bucket effectively improves soil breaking efficiency and extends its service life. Simultaneously, the vent holes prevent negative pressure formation, allowing for easy removal of soil samples. The overall design is simple to operate, easy to carry, adaptable to different soil conditions, and enhances its effectiveness and practicality. Attached Figure Description

[0016] 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.
[0017] Example
[0018] The following is combined with Figures 1 to 3This application introduces a convenient cardboard soil sampler, comprising a bucket 1 and a folding handle 2 connected to the back plate of the bucket 1. The bucket 1 is a bucket-shaped structure with openings at the front and top. The top of the back plate of the bucket 1 has an avoidance notch 3, and a horizontal axis 4 is provided within the notch 3. The folding handle 2, which can rotate 180 degrees with the horizontal axis 4, is connected to the horizontal axis 4 until it is flush with the back plate of the bucket 1. When storage is required, the folding handle 2 is rotated inwards towards the bucket 1, reducing the overall size. At this point, the overall size of the sampler is the same as the size of the bucket, making it relatively neat and easy to carry, whether in a bag, box, or backpack, without taking up much space. When opening, the folding handle 2 is rotated outwards towards the bucket 1. This allows the bucket 1 to be inserted into the soil for soil sampling by holding the folding handle 2.
[0019] like Figure 3 In a further optimized design, the folding handle 2 is a hollow cylindrical structure. A tension spring mounting seat 10, perpendicular to the horizontal axis 4, is fixedly connected to the horizontal axis 4. A tension spring 11 is mounted on the tension spring mounting seat 10. The folding handle 2 is loosely fitted onto the outside of the tension spring mounting seat 10, and the other end of the tension spring 11 is connected to the inner wall of the folding handle 2. The tension spring 11 improves the connection stability between the folding handle 2 and the back plate of the bucket 1, eliminating the need for the operator to provide force to maintain the connection between the folding handle 2 and the back plate of the bucket 1. It also improves stability during folding and storage, providing initial tension and preventing abnormal noises caused by friction and collision between the folding handle 2 and the back plate of the bucket 1 during storage and carrying.
[0020] In a further optimized design, the end face of the folding handle 2 near the back plate of the bucket 1 is provided with a horizontal bar 9 perpendicular to the folding handle 2. The back plate of the bucket 1 is provided with limiting grooves 8 on both sides that are embedded with the horizontal bar 9. When the folding handle 2 is rotated to fit against the back plate of the bucket 1, the horizontal bar 9 falls into the limiting groove 8. Together with the tension spring 11, they form a self-locking structure, which further improves the connection stability between the folding handle 2 and the back plate of the bucket 1.
[0021] In a further optimized design, the end of the folding handle 2 away from the back plate of the bucket 1 is threaded with a spiral ring 5. The spiral ring 5 is connected to a tension spring 11. By adjusting the relative position of the spiral ring 5 and the folding handle 2, the preload of the tension spring 11 can be adjusted to adapt to soils of different strengths, thereby improving applicability and grip comfort.
[0022] In a further optimized design, the front end of the side plate of the bucket 1 is an arc-shaped cut 7, the radius of which is the height of the side plate of the bucket 1. Compared with right-angle or oblique blades, the arc-shaped cut 7 has better strength, can better avoid stress concentration, improve service life, and can also improve soil breaking efficiency.
[0023] In a further optimized design, the bottom, sides, and back of the bucket 1 are provided with ventilation holes 6 to prevent negative pressure from forming inside the bucket 1 due to poor ventilation, thus avoiding the formation of negative pressure in the soil and inside the bucket 1, which would prevent the soil sample from being easily removed. In summary, this application has the advantages of simple operation and good portability.
[0024] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
