Description

Technical Field

[0001] This utility model relates to the field of mine restoration, and in particular to an adjustable grid positioning frame for a pilot area for the revegetation of coal gangue wasteland. Background Technology

[0002] Mine remediation refers to the restoration of polluted mining wastelands to enable the reuse of land resources. Mining operations generate large amounts of land that cannot be used without remediation; these are known as mining wastelands and are subject to various forms of pollution caused by mining activities.

[0003] However, existing revegetation frameworks are usually only used in a single environment, such as the prior art with patent number CN210726129U. Furthermore, they do not form targeted adjustable structures for relatively flat areas and sloping areas, which makes the final revegetation experimental area prone to insufficient plant survival rate due to harsh environment.

[0004] Therefore, to address the above issues, an adjustable grid positioning frame is provided for a pilot area for the revegetation of coal gangue wasteland. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide an adjustable grid positioning frame for a coal gangue wasteland revegetation test area. The main solution is to address the technical problem that the frame structure used for revegetation cannot be adjusted according to the environment.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] This utility model relates to an adjustable grid positioning frame for a coal gangue wasteland revegetation pilot area, comprising a frame support and connecting crossbars. The frame support has a U-shaped structure, and the connecting crossbars are located at the opening of the frame support. Connecting plates are symmetrically located at the bottom of the connecting crossbars and the bottom of the frame support, with fixing teeth installed at the bottom of the connecting plates. Symmetrically installed inclined plates are located on the inner side of the frame support, with the joint between the two inclined plates located in the middle of the connecting crossbars. Planting grooves are provided on the surface of the inclined plates, and springs are installed between the two inclined plates. An inclined baffle is installed on the surface of the frame support, with the inclined baffle having the same vertical projection shape as the frame support. The inclined baffle includes a vertical plate and triangular plates installed at both ends of the vertical plate. A raised plate is installed on the top of the vertical plate, and a fiber mesh is provided inside the raised plate. An inclined block is provided at the bottom of the fiber mesh, with the inclined block tilting towards one side of the inclined plate.

[0008] Preferably, the surface of the vertical plate is further provided with a fastening plate, which is embedded and fastened to the frame bracket, and the top of the fastening plate is provided with an inclined surface facing the inclined plate.

[0009] Preferably, the frame support has through holes on both sides of the top, extending to the bottom, and bolts for mounting the triangular plate are provided inside the through holes.

[0010] Preferably, the bottom of the vertical plate is provided with a recessed cavity, the depth of which is greater than the length of the fixed tooth.

[0011] Preferably, the fiber mesh is composed of multiple layers of plastic fiber mesh material, and the fiber mesh is perpendicular to the two triangular plates on both sides.

[0012] Preferably, the joint between the two inclined plates is a rectangular structure, and the spring is installed at a horizontal angle to fix the two inclined plates.

[0013] Preferably, the inclined plate and the inner wall of the frame support are rotatably connected by a rotating shaft, which is located on the lower side of the fastening plate.

[0014] Preferably, the connecting crossbar and the frame support are fixedly connected by screws, and screw holes of different heights are provided between the connecting crossbar and the frame support.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] This invention utilizes a specially structured inclined baffle and raised disc. On flat ground, these can act as an interception structure for mist or soil particles, achieving a soil covering effect in the planting area. In sloping areas, the installation method of the inclined baffle is changed, allowing the raised disc to act as a soil attachment structure, and the frame support to form a more horizontal structure, enabling plants to easily achieve vertical growth and soil stabilization under sloping conditions.

Detailed Implementation

[0023] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0024] In the attached diagram, all identical reference numerals refer to the same components.

[0025] like Figure 1-3 As shown, this utility model provides an adjustable grid positioning frame for a coal gangue wasteland revegetation pilot area, including a frame support 1 and a connecting crossbar 101. The frame support 1 has a U-shaped structure. The connecting crossbar 101 is located at the opening of the frame support 1. The bottom of the connecting crossbar 101 and the bottom of the frame support 1 are symmetrically provided with connecting plates 2. The bottom of the connecting plates 2 is equipped with fixing teeth 201. The inner side of the frame support 1 is provided with symmetrically installed inclined plates 3. The joint of the inclined plates 3 on both sides is located in the middle of the connecting crossbar 101. The surface of the inclined plates 3 is... A planting trough 301 is provided, and a spring 4 is installed between the two inclined plates 3 on both sides; an inclined baffle 5 is installed on the surface of the frame support 1. The inclined baffle 5 has the same shape as the vertical projection of the frame support 1. The inclined baffle 5 includes a vertical plate 501 and triangular plates 502 installed at both ends of the vertical plate 501. A protruding plate 6 is installed on the top of the vertical plate 501. A fiber mesh 601 is provided on the inner side of the protruding plate 6. An inclined block 602 is provided at the bottom of the fiber mesh 601, and the inclined direction of the inclined block 602 is towards the inclined plate 3.

[0026] Its structure is mainly used in the greening experimental area of ​​coal gangue wasteland. When experimental plants need to be planted in the structure set up in the coal gangue wasteland, the wind is strong and the root system of the vegetation is shallow, and the seedlings are easy to fall over. Traditional frames have no supporting function, and the soil and water are easily lost, especially on the slope. Therefore, an inclined plate 3 is set on the inner side of the frame support 1 to form a planting trough 301 with an angle distribution to support the seedlings.

[0027] At the same time, an inclined baffle 5 is provided for blocking water and dust. The upper part of the inclined baffle 5 is provided with a raised plate 6. When the air is humid, the moisture will stay on the fiber mesh 601 and continue to drip down until it drips back onto the inclined plate 3 from the inclined block 602, so as to form the accumulation of moisture and combine it with the blocked dust to prevent water and soil loss.

[0028] The surface of the vertical plate 501 is also provided with a fastening plate 503, which is embedded and fastened to the frame bracket 1. The top of the fastening plate 503 is provided with an inclined surface facing the inclined plate 3. The vertical plate 501 is provided with a fastening plate 503 structure so that the inclined baffle 5 can be fixed to the frame bracket 1 at the vertical plate 501.

[0029] Both sides of the top of the frame bracket 1 are provided with through holes 7 extending to the bottom. The inside of the through holes 7 is provided with bolts 701 for installing the triangular plate 502. This allows the inclined baffle 5 to be installed by the bolts 701 through the through holes 7 into the threaded holes at the bottom of the triangular plate 502, so that the inclined baffle 5 can be fixed on the frame bracket 1.

[0030] The fiber mesh 601 is composed of multiple layers of plastic fiber mesh 601 material, and the fiber mesh 601 is perpendicular to the two triangular plates 502 on both sides; this makes it easier for humid air to adhere to the fiber mesh 601, and the fiber mesh 601 also increases the degree of dust interception and the interception of agglomerates.

[0031] The joint between the two inclined plates 3 is a rectangular structure, and the spring 4 is installed at a horizontal angle. The spring 4 is used to fix the two inclined plates 3. The inclined plate 3 and the inner wall of the frame bracket 1 are rotatably connected by a rotating shaft 8. The rotating shaft 8 is located on the lower side of the fastening plate 503, so that the inclined plate 3 can be unfolded by rotating the rotating shaft 8 and fixed to each other by the spring 4, making it easy to remove the inclined plate 3 after the plant grows.

[0032] The connecting crossbar 101 is fixedly connected to the frame bracket 1 by screws, and screw holes of different heights are provided between the connecting crossbar 101 and the frame bracket 1; so that the connecting crossbar 101 can be installed at an offset position with the opening of the frame bracket 1, realizing an adjustable connection at the opening.

[0033] The vertical plate 501 is installed on the upper part of the frame support 1. The bottom of the protruding plate 6 is fixedly connected to the vertical plate 501. The inclined baffle 5 is installed on the upper or lower part of the frame support 1. The bottom of the vertical plate 501 is provided with a recessed cavity 504. The depth of the recessed cavity 504 is greater than the length of the fixing tooth 201. This allows the inclined baffle 5 to be installed not only on the upper part of the frame support 1, but also on the lower part of the frame support 1 for fixation, so as to be buried inside the soil.

[0034] Specifically, the overall structure has two different usage methods, namely the conventional method such as Figure 1 As shown, it is mainly placed in a two-dimensional scene. Because coal gangue waste sites often experience frequent soil erosion, and with unobstructed lateral winds, soil particles are more easily stirred up; simultaneously, the moisture in the soil further decreases and evaporates into the air. Therefore, it is designed with... Figure 1The inclined baffle 5 extends upwards and is supported by a raised disc 6 to intercept soil particles in the air. Since the raised disc 6 is also equipped with a fiber mesh 601, moisture in the humid air will also adhere to the fiber mesh 601. That is, soil particles and moisture will combine and agglomerate, and then return along the inclined block 602 to the inside of the frame support 1 and be stored on the inclined plate 3 to form a loose soil cover, so as to achieve the effect of assisting in revegetation.

[0035] In applications with slopes, the fixing teeth 201 alone cannot provide a good fixation method. Therefore, a connecting crossbar 101 that can be installed in a staggered manner is provided. Based on screw holes of different heights, the fixing teeth 201 are embedded in the soil to different degrees on the slope.

[0036] Because soil erosion is more severe under slope conditions, the frame structure is mainly used for soil stabilization. Therefore, the inclined baffle 5 can be installed at the lower part of the frame support 1, such as... Figure 2 As shown, the fiber mesh 601 at the raised plate 6 can also combine with deeper soil to form a soil stabilization effect, and the whole can form a lifting frame structure, so that the inclined frame support 1 avoids excessive inclination angle on the slope, thereby realizing the adjustment and use effect of the whole structure in different environments.

[0037] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
