Description

Technical Field

[0001] The invention relates to the technical field related to tailings sand, and in particular to a tailings sand composite soil ecological restoration device and method. Background Art

[0002] Tailings sand refers to the solid waste generated during the process of mineral extraction in mines. Tailings sand usually has a high density, special chemical composition and large size, and is usually composed of independent particles. The size and shape of these particles vary according to the process of mineral extraction. In some cases, tailings sand will become a dynamic rotation with a threat of sinking, which will cause potential harm to the environment. A large amount of tailings sand accumulation not only occupies a large amount of top land, but also destroys the natural ecological environment of river valley water washing. At the same time, since the harmful substances in tailings sand will seep through groundwater and surface water sources and pollute the environment, ecological restoration work will generally be carried out on tailings sand to solve the problem of large-scale accumulation of tailings sand, reduce water and soil erosion, improve the existing environment of tailings, and improve the water holding capacity of tailings, As well as enhance fertility, it provides a solid foundation for realizing mine ecological restoration and landscape needs. In the current market, when carrying out ecological restoration of mines, organic substrates such as grass seeds and water retaining agents are generally sprayed onto the slopes through sprayers. On the surface, the organic material is precisely combined with the slope under the action of pressure to form a matrix layer for plant growth and development, so the greening of tailings sand can be completed. However, since the tailings sand is generally in an area and height when it is piled up, when it is sprayed by a sprayer, although the traditional sprayer is installed on a car and can run with the car to complete continuous movement work, due to the huge area of ​​spraying, it is necessary to continuously add substrate to the inside of the mixing device for mixing during long-term spraying. However, the weight of the existing substrate is generally heavy and occupies a large space. There is no corresponding storage structure on the sprayer on the existing market. As a result, after the spraying of the substrate on the sprayer is completed, an external transportation device is required to transport the substrate to the vicinity of the car, and then the substrate is manually transferred to the vicinity of the sprayer, and then added to the mixing device of the sprayer for mixing. As a result, the transportation and method of the entire substrate will consume a lot of time, and manual handling and unloading are required, and the work intensity is huge.

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] See also Figure 1-5 The present invention provides a technical solution: a tailings sand composite soil ecological restoration device and method, comprising a mounting base plate 1, which is arranged in a plate-like structure and is used to connect with the top of a transport vehicle, and a hollow structure is arranged on the inner side of the mounting base plate 1; A lifting mechanism 2 is provided in a hollow structure at the bottom of the mounting base plate 1, and a mounting plate 3 is integrally mounted on the top thereof; The spraying body includes a mixing body 5, a pump body 7, a spraying port 8 and a stirring mechanism 11. The mixing body 5 is arranged above the mounting plate 3, and the stirring mechanism 11 for mixing raw materials is arranged inside the mixing body 5. The pump body 7 is arranged outside the top of the mixing body 5, and the top of the pump body 7 is connected to the spraying port 8 through the installation connecting pipe 10. The mixed raw materials can be sprayed on the accumulated tailings sand through the spraying port 8 to perform the greening work of the tailings sand; Also includes; A fixing seat 4, which is fixed on the outside of the mixing body 5 and is used to fix the position of the spraying port 8; A storage mechanism 6, which is arranged at the top of the mixing body 5 and is used for storing raw materials; The stirring mechanism 11 includes a control motor 111 and a stirring blade 112. The control motor 111 is arranged outside the mixing body 5, and the top end of the control motor 111 penetrates the outer wall of the mixing body 5 and is connected to the stirring blade 112. The stirring blade 112 is used to stir and mix the raw materials inside the mixing body 5. The present application provides a tailings sand composite soil ecological restoration device with a storage mechanism 6. Specifically, when in use, firstly, bagged soil and substrate are placed inside the storage mechanism 6, then, a fixed amount of soil, substrate and water are controlled to be poured into the mixing body 5, and then the stirring mechanism 11 is started to mix the soil and substrate. After the mixing is completed, the pump body 7 is started to drive the mixed substrate soil inside the mixing body 5 to the position of the spraying port 8 through the installation connecting pipe 10. Then, the soil substrate is sprayed toward the position of the tailings sand at the spraying port 8 to complete the spraying of the substrate soil. When the mixing of the substrate soil at the top of the mixing body 5 is completed, at this time, there is no need for an external transportation device to re-carry out the transportation and dumping of the substrate and soil. It is only necessary to pour the unused substrate and soil in the storage mechanism 6 into the mixing body 5 to complete the second spraying. After the soil base material is sprayed, the storage mechanism 6 is reloaded with base material, grass seeds, fertilizers, adhesives and water retaining agents, etc., and then a fixed amount of base material, grass seeds, fertilizers, adhesives and water retaining agents are manually controlled to enter the mixing body 5 for overlap, and then the mixed thin water adhesive slurry is sprayed from the spraying port 8 to the tailings sand. After the thin water adhesive slurry in the mixing body 5 is used up, the raw materials in the storage mechanism 6 can be taken again and poured into the mixing body 5 for mixing again, so that continuous feeding and mixing can be carried out. No external conveying device is required for docking and transportation, and the operation is faster and more convenient.

[0019] As a further preferred embodiment of this invention, according to Figure 1-2 The lifting mechanism 2 shown includes a prismatic telescopic frame 21 and a telescopic cylinder 22. The bottom of the prismatic telescopic frame 21 is provided with a telescopic cylinder 22 for driving it to perform lifting work. The top end of one side of the prismatic telescopic frame 21 is arranged inside a reserved slide groove 23 for sliding, and the reserved slide groove 23 is inlaid on the inner wall surface of the hollow structure at the bottom of the installation base plate 1. Specifically, when the height of the tailings sand is high and the spraying body cannot be completely sprayed during transportation by car, the telescopic cylinder 22 can be started to drive the prismatic telescopic frame 21 at its top to extend, thereby causing the prismatic telescopic frame 21 to drive the mounting plate 3 at its top to rise, thereby driving the entire spraying body to rise in height, thereby making it possible to thoroughly spray the higher surface of the tailings sand.

[0020] Among them, according to Figure 2-4 As shown, the inner side of the fixing seat 4 is connected to the spraying port 8 by an axis, and the axis inside the fixing seat 4 is set toward the bottom position of the fixing seat 4, the middle of the installation connecting pipe 10 connected to the bottom of the spraying port 8 is a PVC telescopic material, and the top ends of both sides of the installation connecting pipe 10 are respectively connected to the pump body 7 and the spraying port 8 by threaded disassembly installation; Specifically, when the spraying work is carried out through the spraying port 8, since the spraying port 8 and the fixed seat 4 are connected by an axis, when controlling the spraying port 8 for spraying, the angle of the spraying port 8 can be flexibly adjusted by the axis, so that the spraying port 8 is fan-shaped and the spraying is uniform. At the same time, after the use of the spraying port 8, since the axis and the outer wall circular groove of the spraying port 8 are mutually engaged, and the engaging position is a rough specific surface, the spraying port 8 can be controlled to be vertically upward to ensure that the substrate accumulated inside it can fall into the inside of the installation connecting pipe 10. Therefore, when the inside of the installation connecting pipe 10 is blocked, since it and the pump body 7 and the spraying port 8 are all threaded disassembly installation structures, it can be flexibly replaced with lower cost.

[0021] Furthermore, according to Figure 5-6 As shown, a rectangular feeding port 51 is passed through the top of the mixing body 5, and a connecting knife 52 is protruding from the middle of the feeding port 51, and a circular storage mechanism 6 is arranged outside the feeding port 51; Specifically, when the substrate, soil or grass seeds in the bag inside the control storage mechanism 6 are unloaded, the packaging bag can be directly placed at the position of the unloading port 51. Since a connecting knife 52 is provided at the top of the unloading port 51, it can cut the bottom of the packaging bag, so the unloading work can be carried out. Afterwards, the staff only needs to take and collect the packaging bags after unloading.

[0022] In this application, according to Figure 5-6As shown, the storage mechanism 6 includes a fixing mechanism and a rotating disk 64, and the rotating disk 64 is arranged at the bottom of the fixing mechanism for rotation. The fixing mechanism includes a fixing plate 61, a cover plate 62 and a connecting plate 63, and the fixing plate 61 and the connecting plate 63 are both arranged in an arc-shaped structure, and the fixing plate 61 and the connecting plate 63 are arranged with a concentric structure, and the fixing plate 61 is arranged on the inner side of the connecting plate 63, and its bottom is integrally installed with the top of the mixing body 5.

[0023] The top of the connecting plate 63 is connected to the fixed plate 61 through the cover plate 62, and the cover plate 62 is engaged with the top of the fixed plate 61 and the connecting plate 63. The bottom of the connecting plate 63 is arranged above the rotating disk 64, and it does not contact the rotating disk 64. The outer side of the rotating disk 64 is evenly distributed with gear blocks, and the rotating disk 64 is meshed with the driving mechanism 12 and is driven by the driving mechanism 12 to rotate.

[0024] The fixed plate 61 and the connecting plate 63 are both provided with reserved grooves 13 correspondingly, and a pushing mechanism 9 is provided outside the reserved grooves 13 for pushing the raw materials placed on the rotating disk 64 to the position of the unloading port 51 .

[0025] The pushing mechanism 9 includes a mounting seat 91, a cylinder 92 and a push plate 93. The mounting seat 91 is fixed at the top position of one side of the mixing body 5, and its top is connected to the push plate 93 through the cylinder 92. The position of the push plate 93 corresponds to the position of the reserved groove 13, and it can move inside the reserved groove 13.

[0026] The driving mechanism 12 includes a driving motor 121 and a rotating gear 122. The driving mechanism 12 is arranged on the outer side of the rotating disk 64. The bottom of the driving motor 121 is coaxially connected with the rotating gear 122, and the outer side of the rotating gear 122 is meshed with the gear block on the rotating disk 64. Specifically, since the single drop volume of substrate, grass seeds and soil is huge, it is necessary to store a large amount of substrate, grass seeds and soil. First, the cover plate 62 needs to be removed above the fixed plate 61 and the connecting plate 63 for unloading. After that, various packaging bags can be piled up between the fixed plate 61 and the connecting plate 63. Then, the cover plate 62 is closed. Then, water retaining agent, adhesive and fertilizer and other raw materials are placed in the two placement cabinets on one side of the mixing body 5. After placement, they can be passed into the mixing body 5 for mixing. When mixing, when it is necessary to unload the substrate, grass seeds and soil, first of all, it is necessary to start the drive motor 121 so that it drives the rotating gear 1 at its top. 22 rotates, and when the rotating gear 122 rotates, it will mesh with the tooth block on the outside of the rotating disk 64, so that the various materials piled on the rotating disk 64 rotate. When a certain material needs to be dropped, its position is made to correspond to the position of the reserved groove 13 on the connecting plate 63 and the fixed plate 61. Then, the oil cylinder 92 is started to drive the push plate 93 on its top to move, so that the push plate 93 pushes the packaging bag to the top of the discharge port 51, and is broken by the connecting knife 52 for discharge. Afterwards, when other materials need to be dropped in proportion, it is only necessary to take the materials placed inside the cabinet from the outside and drop them. During the whole process, the staff does not need to perform heavy physical labor, and the operation is more labor-saving and convenient.

[0027] Another technical solution provided by the present invention is a method for ecological restoration of tailings sand composite soil, comprising the following steps: Step 1: Hanging nets, first hang nets on the surface of the tailings sand; Step 2: For the bottom layer spraying work, the soil and the high-performance spraying base material are poured into the interior of the mixing body 5, and the mixing mechanism 11 performs the exchange and mixing work. After that, the pump body 7 is started, so that the pump body 7 drives the mixed base material soil to be sprayed above the tailings mine to perform the bottom layer spraying work; Step three: seed layer spraying work, mix the high-performance spraying base material and water, after the spraying base material is fully melted, add planting seeds, soil conditioner, organic fertilizer and compound fertilizer in turn and stir and mix, then add water retaining agent and mix, finally add adhesive and mix to form a thin water-bonded slurry, then spray through the spraying body, finally, wait for a certain period of time for the seeds to germinate, and the soil regreening work is completed.
