Description
Technical Field
[0001] The utility model relates to the technical field of grassland ecology, in particular to a portable hammering soil sampling tool for alpine grasslands. Background Art
[0002] Under the background of the current full implementation of the national grassland basic situation survey, grassland ecological protection, and grassland soil sampling and monitoring, the quality control of the grassland soil environment quality monitoring must be carried out in strict accordance with relevant technical specifications and standards throughout the whole process, and quality control work such as on-site sampling site layout, transportation and transfer, sample preparation and preservation, laboratory analysis, and data processing and review should be done well.
[0003] Soil sampling is an important means to obtain basic soil data. The surface turf of alpine grasslands is firm and the underground root systems are dense, making soil sampling and convenient extraction relatively difficult. Therefore, it is very important to develop a type of soil sampling tool suitable for alpine grasslands to achieve efficient soil sampling and convenient extraction. After collecting grassland soil samples, biological information such as soil type, structure, mechanical composition, pH value, nutrient content, and microorganisms is analyzed. Efficient soil sampling and accurate soil analysis are the basis for implementing soil testing and formulated fertilization in grasslands, and are also effective means for grassland improvement, vegetation restoration, and comprehensive grassland management. The Qinghai-Tibet Plateau is the largest plateau in China and the highest in the world, known as the "Roof of the World" and the "Third Pole", and has an important strategic position in China and even the world. Alpine grasslands are the main land types and ecosystems on the Qinghai-Tibet Plateau. Therefore, tools suitable for soil sampling in alpine grasslands are of great significance for evaluating the soil quality in alpine regions, including the health status, productivity, and ecological functions of the soil, and are crucial for protecting soil resources, ensuring ecological security, and ecological civilization. Moreover, the data and information provided by soil sampling are the basis for research and application. Through detailed analysis of soil samples, scientific researchers can better understand the interaction between soil and the environment, and promote the development of related disciplines.
[0004] Grassland soil collection is a basic and important task. When conducting soil sampling, there are already special tools for collecting soil. There are many types of grasslands in China, and the soil types vary greatly. Traditional sampling tools are not very suitable for soil sampling in high-altitude alpine grasslands. The surface soil of alpine grasslands is firm, the vegetation is dense, and the existing tools for collecting soil have the defects of unfavorable soil extraction, time-consuming and laborious, and inconvenient collection.

[0026] Embodiment 1
[0027] This embodiment provides a portable hammering soil sampling tool for alpine grasslands, hereinafter simply referred to as a soil drill. As Figure 1 , the soil drill is divided into two parts: the upper part is the drill rod, and the lower part is the drill body 12. The drill rod and the drill body 12 are detachable, which is convenient for carrying outdoors. At the upper end of the first drill rod 14 in the figure is a rod-shaped first handle 1. The lower end of the first handle 1 is fixedly connected to the first connecting rod 2, and the lower end of the first connecting rod 2 is provided with a first connecting rod thread 6. As Figure 3 , Figure 4 , the drill body 12 is cylindrical. Scale lines 5 are provided on both the outer wall and the inner wall of the drill body 12, which is convenient for observing the depth of the drill body 12 inserted into the soil and for taking soil samples in layers; at the open end of the lower end of the drill body 12 is a knife-edge 8 with a 45° inclined opening; the upper necking 4 at the upper end of the drill body 12 is a reduced diameter of the drill body 12, and the inner wall of the upper necking 4 is provided with a necking thread 7. The circular connecting piece 3 is fixed to the upper necking 4 through this necking thread 7; a connecting nut is fixedly provided at the center of the connecting piece 3. The first connecting rod 2 is coupled and fixed to the connecting nut through the first connecting rod thread 6 to connect the first drill rod 14 and the drill body 12; both the drill body 12 and the connecting piece 3 are made of stainless steel.
[0028] The outer diameter of the drill body 12 is 40 - 50 mm, the height of the drill body 12 is 300 - 400 mm, the outer diameter of the first handle 1 of the first drill rod 14 is 30 mm, and the length is 30 mm; by fixing the first drill rod 14 and the connecting piece 3, and fixing the connecting piece 3 and the upper necking 4, in addition to using a hammer to strike, the first handle 1 can also be sleeved with a plastic sleeve to increase friction, which is convenient for holding and anti-slip, and can conveniently collect soft soil.
[0029] Embodiment 2
[0030] As Figure 2 , Figure 5 , Figure 6 , in this embodiment, a second drill rod 13 is further included. The second drill rod 13 is used to replace the first drill rod 14, and the second drill rod 13 is connected to the drill body 12. The drill body 12 in this embodiment is exactly the same as that in Embodiment 1. Different from Embodiment 1, the second handle 9 of the second drill rod 13 is circular plate-shaped, with an outer diameter of 50 mm and a thickness of 10 mm; it is fixed to the lower end of the second handle 9 through the second connecting rod 10, and the second connecting rod 10 is fixed to the connecting nut at the center of the connecting piece 3 through the second connecting rod thread 11 at its lower end, and the connecting piece 3 is threadedly fixed to the upper necking 4.
[0031] Since the top surface of the second handle 9 is flat, it is suitable for precisely hitting with a hammer, enabling the drill body 12 to collect compact soil in a more labor-saving manner.
[0032] During specific use, the first drill pipe 14 can be fixed to the drill body 12. First, the connecting piece 3 is fixed to the upper closing opening 4. After it is fixed, the first connecting rod 2 is screwed and fixed with the connecting nut of the connecting piece 3 through the first connecting rod thread 6. At this time, drilling can be directly carried out in relatively soft soil. After drilling to the required depth according to the scale line 5, the soil drill can be lifted upward.
[0033] If it is necessary to take samples from compact soil, remove the first drill pipe 14 and screw the second drill pipe 13 into the connecting piece 3. After it is fixed, rotate it in the opposite direction of the connecting piece 3 so that the connecting piece 3 can move up and down. At this time, the second handle 9 can be hammered downward with the help of external force to collect soil samples.
[0034] Such as Figure 6 , for example, during the process of taking out the soil in the drill body 12 after sampling and drilling, when encountering soil with a relatively high compactness embedded in the drill body 12, the second connecting rod 10 can also be directly inserted from the top of the drill body 12 and connected to the connecting nut of the connecting piece 3, unscrew the connecting piece 3 from the drill body closing opening of the drill body 12, and hammer the second handle 9 from top to bottom to hammer out the soil adhering to the inside of the drill body.
[0035] The utility model has a simple structure, is convenient to operate, is easy to carry, does not damage the grassland ecological environment, can realize fast or labor-saving soil sample collection by switching the first and second handles, effectively reduces the labor and time costs, and provides convenience for field collection work.
[0036] The above embodiments are only the preferred embodiments of the utility model, and the protection scope of the utility model is not limited to the above embodiments. All technical solutions falling within the idea of the utility model belong to the protection scope of the utility model. It should be pointed out that for those of ordinary skill in the art in this technical field, improvements and refinements made without departing from the principle of the utility model should also be regarded as within the protection scope of the utility model.
