Description

A composite sustained-release carrier structure based on arbuscular mycorrhizal fungi Technical Field

[0001] This utility model relates to the field of soil remediation technology, specifically to a composite slow-release carrier structure based on arbuscular mycorrhizal fungi. Background Technology

[0002] In the field of soil remediation, existing methods involve laying a remediation structure on the surface of the soil to be remediated. However, the surface of the soil contains many impurities, which can affect the remediation structure. If the soil is turned over in one go, other substances may be mixed in and enter the soil, damaging the remediation process. Turning over the soil during the laying process can also put a strain on manual hands and affect the laying efficiency. Therefore, a composite slow-release carrier structure based on arbuscular mycorrhizal fungi is proposed. Summary of the Invention

[0003] To address the problems existing in the prior art, the purpose of this utility model is to provide a composite slow-release carrier structure based on arbuscular mycorrhizal fungi, which can turn over the soil during the laying process, allowing the soil remediation structure to come into contact with the internal components of the soil, thereby avoiding the influence of the soil surface and accelerating the remediation process.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a composite slow-release carrier structure based on arbuscular mycorrhizal fungi, including a fence, a support member provided at the bottom of the fence, the support member and the fence together loading a composite slow-release structure, the composite slow-release structure including an adsorption layer, a slow-release layer, a planting layer and a film layer, the support member including two support frames, each support frame having multiple scrapers inside, each support frame having a pull rod rotatably connected to it, and each support frame being slidably connected to the fence.

[0005] In some embodiments, the adsorption layer is a porous structure composed of biochar and biodegradable polymer, the slow-release layer is AMF spores and mycelial fragments, and the planting layer is a pre-embedded layer of tolerant plant seeds.

[0006] In some embodiments, each of the two crossbars of each pull rod includes a sliding rod and a fixed rod. Each sliding rod has a sliding groove, and each fixed rod is provided with a bolt. Each bolt is slidably connected to a sliding groove.

[0007] In some embodiments, a pressure plate is also included, wherein the pressure plate is provided with a handle, the handle being in the shape of a "Z".

[0008] In some embodiments, the bottom of the enclosure is provided with an elongated groove, the ends of which are provided with blocking portions, and T-shaped strips are provided on both sides of each supporting frame.

[0009] In some embodiments, a washer is provided between the bolt and the groove.

[0010] In summary, this utility model has the following beneficial effects:

[0011] This utility model is equipped with a barrier and a support component. It can not only store the composite slow-release structure and cultivate it for a period of time before laying it, so as to better exert the effect of the composite slow-release structure, but also use the scraper on the support frame in the support component to split the film layer of the composite slow-release structure and the soil surface layer during the laying of the composite slow-release structure, so that the internal components of the soil can be directly connected with the composite slow-release structure, eliminating the obstruction of the soil surface structure and accelerating the soil remediation process.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0017] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0019] Referring to Figures 1-3, a composite slow-release carrier structure based on arbuscular mycorrhizal fungi includes a enclosure 1. A support 3 is provided at the bottom of the enclosure 1. The support 3 and the enclosure 1 together load the composite slow-release structure. The composite slow-release structure includes an adsorption layer, a slow-release layer, a planting layer and a film layer from top to bottom. The support 3 includes two support frames 37. Each support frame 37 is provided with multiple scrapers 36. Each support frame 37 is rotatably connected to a pull rod 31. Each support frame 37 is slidably connected to the enclosure 1. In use, the operator first places the composite slow-release structure into the space formed by the combination of the support 3 and the enclosure 1, then places the entire device on the soil to be repaired. Next, the operator grasps the two pull rods 31 and applies downward force, causing the scraper 36 on the support frame 37 to penetrate into the soil. Then, the operator presses the composite slow-release structure, causing the film layer in the composite slow-release structure to be punctured by the scraper 36. The operator then controls the two pull rods 31 to move in opposite directions, and each of the two pull rods 31 drives one support frame 37 to move. This causes the scraper 36 on the two support frames 37 to not only dig and remove the soil surface obstructions, exposing the internal components of the soil, but also to break the film layer, allowing the planting layer of the composite slow-release structure to come into contact with the soil interior. This increases the contact degree between the composite slow-release structure and the soil, accelerating the soil recovery process. The operator can use multiple of these devices to lay them in a grid pattern, thereby achieving large-area soil remediation.

[0020] In some embodiments, the adsorption layer is a porous structure composed of biochar and biodegradable polymer, the slow-release layer is composed of AMF spores and mycelial fragments, and the planting layer is a layer of pre-embedded tolerant plant seeds. By targeting heavy metals with the porous biochar in the adsorption layer, and by using the polylactic acid gradient slow-release AMF agent in the middle layer and the pre-embedded tolerant plant seeds, a synergistic effect of agent activity protection and precise release is achieved. Simultaneously, the agent activation mechanism is triggered by root growth, thereby simultaneously completing heavy metal passivation, mycorrhizal network construction, and soil microecological reconstruction, shortening the remediation cycle and reducing costs.

[0021] In some embodiments, each pull rod 31 has two crossbars, each including a sliding rod 32 and a fixing rod 35. Each sliding rod 32 has a groove 33, and each fixing rod 35 has a bolt 34. Each bolt 34 is slidably connected to a groove 33. When the operator places the transport composite slow-release structure onto the support 3, the operator loosens the bolt 34 and pulls the pull rod 31 upward. The pull rod 31 moves the sliding rod 32 upward. Then, the operator rotates the two pull rods 34 toward both sides of the enclosure 1, so that the top of the enclosure 1 is no longer blocked by the pull rods 31. The operator can then place the composite slow-release structure inside. After placement, the operator can rotate the pull rod 31 and then reset it. Finally, the bolts 34 are tightened to fix the sliding rod 32, thereby loading the composite slow-release structure inside.

[0022] In some embodiments, a pressure plate 2 is also included, and a handle 21 is provided on the pressure plate 2. The handle 21 is shaped like a "Z". The operator can cover the composite slow-release structure with the pressure plate 2 for easy transportation. At the same time, the operator can use the handle 21 to press the pressure plate 2 downward. When the composite slow-release structure is placed on the designated soil surface, the pressing of the pressure plate 2 makes the composite slow-release structure make closer contact with the soil surface, thereby improving the remediation speed.

[0023] In some embodiments, the bottom of the enclosure 1 is provided with an elongated groove 11, and each end of the elongated groove 11 is provided with a blocking part 12. Each support frame 37 is provided with a T-shaped strip 38 on both sides. When the operator moves the support member 3, the T-shaped strip 38 on the support frame 37 slides in the elongated groove 11. The cross-section of the elongated groove 11 is T-shaped. When it moves to the end of the enclosure 1, the T-shaped strip 38 is blocked by the blocking part 12 to prevent the support frame 37 from being pulled out of the enclosure 11.

[0024] In some embodiments, a washer is provided between the bolt 34 and the slide 33. The washer allows for a larger contact area between the bolt 34 and the slide rod 32 and the fixing rod 33 when the bolt 34 is tightened, thereby enhancing the fixing strength of the bolt 34 to the slide rod 32 and the fixing rod 33.

[0025] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
