Description

Technical Field

[0001] The present invention relates to the technical field of soil analysis devices and equipment, and in particular to a device for separating and collecting moss crust soil. Background Art

[0002] Biological soil crusts, also known as biological soil crusts or soil microbial crusts, are complexes formed by the bonding of microbial life forms such as microbes, fungi, algae, lichens, mosses, and other cryptogamous plants, their hyphae, and secretions, with soil gravel. They represent an important surface cover (over 40%) in arid and semi-arid regions. They are also one of the most distinctive biological landscapes in some areas of soil desertification. Their presence is crucial for the stability of deserts, the physical, chemical, and biological properties of the soil surface, and soil resistance to wind and water erosion. They are also pioneer species in desert vegetation succession and play a vital role in promoting desert vegetation evolution. The fragile geological environment and intense human activity in karst environments have led to frequent desertification, exposing surface soil to erosion and creating a typical soil environment prone to severe soil and water erosion. Moss crust is an important surface cover in rocky desertification ecosystems. Research on local crusted soil is often a key point in the process of investigating and studying the ecological functions of moss crusts. Soil samples collected from the wild must have a certain moss crust layer. In order to obtain soil samples with higher purity for experiments, the soil needs to be separated from the crust layer in the conventional operation process; but the current method of soil separation is generally for the operator to turn the crust layer over and then use a scraper or brush to directly scrape the soil off. This operation method is obviously very labor-intensive. At the same time, it is easy to scrape off the moss with the brush during operation, making it impossible to obtain soil with higher purity. This is the main problem currently faced. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a device for separating and collecting moss crust soil, so as to solve the problem that the labor efficiency is low and moss impurities are easily brushed into the scraped soil in the current process of directly using a scraper to separate soil from the moss crust layer.

[0006] Preferably, a group of oppositely placed ear plates are provided on a side edge of the top of the box body; through holes are opened on the ear plates, and the two ends of the movable end cover are hingedly installed between the ear plates through the through holes; and limit blocks are provided between the ear plates for limiting the rotation of the movable end cover.

[0007] Furthermore, the movable end cover and the limiting block are both cylindrical arc-shaped plate structures, and the two can be spliced ​​into a whole; the bottom of the limiting block extends to the opening end of the box body.

[0008] Furthermore, mutually cooperating buckles are installed on the same side end of the movable end cover and the box body; and a torsion spring is also provided between the movable end cover and the ear plate; when the torsion spring is in a natural state, the movable end cover is in an open state.

[0014] Beneficial effects of the present invention:

[0015] The present invention designs a device that can conveniently separate soil from moss crusts. The device is composed of a box with a hinged movable end cover, and a fixing device that can fix the soil crust is provided on the end cover. At the same time, a scraper is configured on the box body, so that the operator can use the scraper to separate and scrape the moss crust that is reversely fixed on the end cover to separate the soil. A screen is further provided on the box body to screen out the moss crust tissue that falls off during the scraping, which greatly reduces the labor intensity of current soil separation and improves the efficiency of operation. On the other hand, the device has a simple structure, is firmly fixed, is easy to process and produce, and has good promotion prospects. BRIEF DESCRIPTION OF THE DRAWINGS
