A field sampling device suitable for various types of solid samples from the surface environment.

Abstract

This utility model discloses a field sampling device suitable for various types of surface solid samples, including a handle and a protective cover for the spiral head. The protective cover fits onto the top of the handle, and a rotating seat is provided on the handle. A fixing mechanism is provided inside the rotating seat. This utility model features a multi-functional rotating spiral head, enabling efficient collection of various types of surface solid samples. The complete structure facilitates the acquisition of samples from some hard surface environments, such as ice layers and relatively dense soil. The disassembled structure is mainly used to smoothly transfer samples to sample containers. It is also suitable for collecting general surface solid samples, such as snow samples, river sediment, loose soil, and even some plant samples, demonstrating strong applicability. The cover design not only protects the spiral head but also facilitates storage and carrying. Compared with common surface collection tools such as shovels, it saves more space.

Description

Technical Field

[0001] This utility model relates to the field of field sampling technology, specifically a field sampling device suitable for various types of solid samples from the surface environment. Background Technology

[0002] Sampling work in high-altitude and cold regions usually relies on manual operation, and the sampling tools used are mostly lightweight and easy to carry, such as small garden shovels. However, due to the complex and changeable field environment, the applicability of such tools is often limited. For example, in hard surface environments (such as glacier surfaces or permafrost), existing tools are difficult to meet the requirements of the user's force application and operating efficiency in terms of strength and structure during the sampling process.

[0003] In addition, there are some problems in the sample transfer process. For example, although the commonly used wide-bladed hard shovel can be used to collect samples from hard ice or dense soil, its shape does not match the large-diameter sampling bottles commonly used in experiments, resulting in low sample transfer efficiency and even increasing the risk of secondary contamination.

[0004] High operational intensity requirements: The sampling process not only requires sturdy and durable tools, but also places high demands on the physical strength and operational skills of the sampling personnel, increasing the workload;

[0005] Poor compatibility between tools and containers: The shape and size of commonly used sampling tools are often incompatible with sample containers (such as large-diameter sampling bottles), which makes the sample transfer process cumbersome, inefficient, and may introduce secondary contamination.

[0006] Limited functionality: Existing sampling tools are mostly single-function, making it difficult to efficiently complete a series of operations such as sampling, transfer and subsequent processing in complex environments, which limits their wide applicability and convenience in the field.

[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] Please see Figure 1-5 The present invention provides an embodiment of a field sampling device suitable for various types of solid samples from the surface environment, comprising a handle 1 and a spiral head protective cover 2. The spiral head protective cover 2 covers the top of the handle 1. A rotating seat 3 is provided on the handle 1. A fixing mechanism is provided inside the rotating seat 3. The rotating seat 3 is connected to the spiral head 4 through the fixing mechanism. An electric drive mechanism 5 is provided inside the handle 1. The electric drive mechanism 5 is a motor, and the output end of the electric drive mechanism 5 is fixedly connected to the bottom of the rotating seat 3. A control switch is provided on the handle 1. A frosted layer is provided on the outer side of the spiral head protective cover 2. A lower compartment cover is provided at the bottom of the handle 1, and a hanging ring is provided on the lower compartment cover.

[0027] The spiral head 4 includes a through hole 41 and a shovel head 42. Multiple sets of through holes 41 are provided on the outer side of the spiral head 4. The spiral head 4 has a cavity inside, and the shovel head 42 is provided inside the cavity. The spiral head 4 is a conical drill bit. The through holes 41 are connected to the inside of the spiral head 4, and the cavity inside the spiral head 4 is inserted into the shovel head 42.

[0028] The fixing mechanism includes a through-hole 31, a slide bar 32, a button 33, and a plug 34. The through-hole 31 is located in the middle of the outer side of the rotating seat 3. Two sets of slide bars 32 are slidably connected inside the through-hole 31. One end of the slide bar 32 extends to the outside of the rotating seat 3 and is provided with a button 33. The other end of the slide bar 32 extends to the inside of the rotating seat 3 and is provided with a plug 34. Insertion holes 35 are evenly opened at the bottom of the outer side of the spiral head 4. The plug 34 is inserted into the insertion hole 35. A spring 36 is connected between the two sets of plug 34.

[0029] Working principle:

[0030] The device mainly consists of a slender, semi-detachable spiral head 4, a handle 1, and a spiral head protective cover 2. The spiral head protective cover 2 is primarily used to protect and store the spiral head. The semi-detachable spiral head 4 has a hollow structure and consists of two parts: one part is fixedly connected to the handle 1, and the other part can be manually removed, exposing the shovel head 42, thus converting it into a small shovel for sampling in different environments. The handle 1 contains an electric drive mechanism 5, which drives the spiral head 4 to rotate, thereby improving the sampling efficiency of hard ice layers or dense soil.

[0031] By pressing the two sets of buttons 33, the springs 36 are compressed against each other, thereby driving the two sets of slide rods 32 inside the port 31, thereby driving the insertion rod 34 to release the fixation on the insertion hole 35, so as to disassemble the spiral head and discharge the collected sample.
