Description

Technical Field

[0001] This utility model belongs to the field of sample collection technology, specifically relating to a soil sampling device. Background Technology

[0002] Currently, soil samplers are mainly divided into surface samplers and subsurface samplers. Surface samplers mainly collect and store samples using collection tools and sampling bottles. Surface samplers require both hands to operate, and soil is easily spilled onto hands during the shoveling and placement into the bottle. While surface sampling itself is simple, the need to occupy both hands during the operation causes inconvenience. Utility Model Content

[0003] This utility model provides a soil sampling device that is simple and convenient to use, has a simple structure, low manufacturing cost, and can achieve collection and bottling operations with one hand.

[0004] This utility model provides the following technical solution: including: a sampler, a connecting component, and a sample collection bottle;

[0005] The sampler has a channel in the middle to accommodate soil sample movement. The sampler and the sample collection bottle are connected by the connecting component. The sampler and the connecting component are located at the grip. The sample collection bottle is surrounded inside the sampler and the connecting component, and the sample collection bottle is connected to the soil sample movement channel of the sampler.

[0006] The sampler consists of three parts: a gripping part, a shoveling part, and a supporting part. The top of the gripping part has a connecting groove, and the bottom of the supporting part has a cover groove.

[0007] The connecting component includes an H-shaped insert plate, a top cover plate, and a connecting unit. The H-shaped insert plate slides inside the connecting groove, and the top cover plate is rotatably connected to the H-shaped insert plate through the connecting unit. The top cover plate and the support portion close to form a gripping surface.

[0008] The H-shaped insert plate has a conical opening fixedly connected to the bottom, which communicates with the soil sample movement channel. The conical opening is located inside the gripping part, and an insertion tube is fixedly connected to the end of the conical opening. A rubber protruding ring is fixedly connected to the circumferential side of the insertion tube.

[0009] The sample collection bottle is fixedly connected to a sealing cap by a belt body. The belt body slides inside the cap groove. The sealing cap is located outside the support part. The inner wall of the sample collection bottle has an annular groove. The annular groove is sleeved on the outside of the insertion tube, and the rubber protrusion ring is located inside the annular groove.

[0010] The sealing surface of the sealing cap has a raised ring that mates with the annular groove.

[0011] The sampler is cylindrical in shape.

[0012] The beneficial effects of this utility model are:

[0013] This technical solution connects the sampler to the sample collection bottle, forming a straight collection channel between them. Based on the action of shoveling soil, it uses a continuous action of shoveling down and lifting up to complete the collection, achieving a two-step process of collection and storage. This avoids the problem of soil spillage caused by operating with both hands.

[0014] Building upon the aforementioned advantages, the structural composition is optimized by disassembling the structure according to usage and structural characteristics. This reduces processing difficulty and thus manufacturing costs, while also optimizing the structural shape to achieve a seamless insertion between the bottle body and the grip, meeting grip area requirements while reducing the difficulty of connecting the bottle body.

[0015] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0020] Please see Figures 1-3 The present invention provides the following technical solution: including: sampler 1, connecting component 2, and sample collection bottle 3;

[0021] The sampler 1 has a channel in the middle to accommodate the movement of soil samples. The sampler 1 and the sample collection bottle 3 are connected by a connecting component 2. The sampler 1 and the connecting component 2 are located at the grip. The sample collection bottle 3 is surrounded inside the sampler 1 and the connecting component 2, and the sample collection bottle 3 is connected to the soil sample movement channel of the sampler 1.

[0022] In this implementation plan: the middle part of the sampler 1 forms a channel for collecting soil samples. Since the sampler 1 is generally made of bent and stamped metal sheet, it is impossible to create a structure for centralized collection inside the sampler 1. Therefore, in order to ensure the integrity of the sampler 1, a connecting component 2 is provided. The connecting component 2 can serve as a connection between the sample collection bottle 3 and the sampler 1, and divides the product into three parts: a continuous use part, a connecting part, and a consumable part.

[0023] The specific method is as follows:

[0024] The sampler 1 consists of three parts: a gripping part 11, a shoveling part 12, and a support part 13. The top of the gripping part 11 has a connecting groove 15, and the bottom of the support part 13 has a cover groove 14.

[0025] During the processing of sampler 1, a metal plate is punched using a die, and the die presses the metal plate to simultaneously form the gripping part 11, the shoveling part 12, the support part 13, the cover groove 14, and the connecting groove 15. The integrated metal plate structure is stable and meets the strength and service life requirements for shoveling. At the same time, the cover groove 14 and the connecting groove 15 provide the conditions for subsequent installation.

[0026] The connecting component 2 includes an H-shaped insert plate 21, an upper cover plate 22, and a connecting unit 23. The H-shaped insert plate 21 slides inside the connecting groove 15. The upper cover plate 22 is rotatably connected to the H-shaped insert plate 21 through the connecting unit 23. The upper cover plate 22 and the support part 13 are closed to form a gripping surface. A conical opening 24 communicating with the soil sample movement channel is fixedly connected to the lower part of the H-shaped insert plate 21. The conical opening 24 is located inside the gripping part 11. An insertion pipe 25 is fixedly connected to the end of the conical opening 24. A rubber protrusion ring 26 is fixedly connected to the circumferential side of the insertion pipe 25.

[0027] The manufacturing difficulty of the H-shaped insert 21 and the conical opening 24 increases. The conical opening 24 can be made by stamping, while the H-shaped insert 21 can be made by casting, injection molding, or CNC machining. Since the connection between the H-shaped insert 21 and the conical opening 24 is only affected by the gravity of the soil, they can be made by welding. If further reduction in processing costs is desired, the H-shaped insert 21 and the conical opening 24 can be integrally molded by injection molding. The H-shaped insert 21 is inserted into the cover groove 14, and the conical opening 24 enters the channel of the sampler 1 as the H-shaped insert 21 is inserted. By holding the grip part 11 and lifting the soil-shoveling part 12, the soil sample can be lifted into the sample collection bottle 3 under the influence of gravity, thus completing the collection.

[0028] The connecting unit 23 can adopt a hinge structure, such as a hinge, to achieve a rotatable connection between the upper cover plate 22 and the H-shaped insert plate 21. Further connecting units 23 can be structures such as metal strips or fabric strips. The connecting unit 23 only needs to connect the upper cover plate 22 and the H-shaped insert plate 21. In use, the upper cover plate 22 is simply snapped into the support part 13 to increase the gripping surface. If there are concerns about misalignment between the upper cover plate 22 and the support part 13, some slot-like positioning structures can be provided between the support part 13 and the upper cover plate 22. This reduces the difficulty of inserting the sample collection bottle 3, allowing it to enter the gripping part 11 and the support part 13, thus reducing the overall length.

[0029] Before use, the sample collection bottle 3 can be inserted into the insertion tube 25 in advance. With the upper cover plate 22 and the support part 13 in cooperation and sealing, the sample collection bottle 3 will not be squeezed. When sampling is required, the soil is directly collected and lifted by the soil shovel part 12. The soil naturally enters the sample collection bottle 3 through the conical mouth 24 and the insertion tube 25, making the operation very convenient.

[0030] The sample collection bottle 3 is fixedly connected to the sealing cap 32 by a belt body. The belt body slides inside the cap groove 14. The sealing cap 32 is located outside the support part 13. The inner wall of the sample collection bottle 3 is provided with an annular groove 31. The annular groove 31 is sleeved on the outside of the insertion tube 25, and the rubber protrusion ring 26 is located inside the annular groove 31.

[0031] Multiple sample collection bottles 3 are typically provided. Under normal conditions, the sealing cap 32 seals the sample collection bottle 3. In use, simply open the sealing cap 32 to expose the open end of the sample collection bottle 3, insert the sample collection bottle 3 into the insertion tube 25, and the rubber protrusion ring 26 will elastically deform and engage within the annular groove 31 to complete the insertion. The engagement between the annular groove 31 and the rubber protrusion ring 26 makes it difficult for the sample collection bottle 3 to separate from the insertion tube 25.

[0032] The sealing surface of the sealing cap 32 has a raised ring that mates with the annular groove 31; similarly, the sealing cap 32 can also utilize the characteristics of the annular groove 31 to increase the stability of the assembly between the sealing cap 32 and the sample collection bottle 3.

[0033] Sampler 1 is cylindrical in shape. The cylindrical sampler 1 is easier to process and has a rounded structure that makes it easy to hold.
