Description

Technical Field

[0001] This invention mainly relates to the field of ecological restoration technology for mine slopes, and specifically to an ecological restoration device for abandoned mine slopes. Background Technology

[0002] Mineral resource development is a fundamental industry in my country. With the rapid development of my country's national economy, the demand for mineral resources will continue to increase. Once a mine has completed its mission, it is generally abandoned. The more mines that are mined, the more abandoned mines there will be. The slopes of abandoned mines are mostly characterized by loose soil, making it difficult for plants to survive. They are easily weathered by the wind and may also experience geological disasters such as landslides and mudslides during rainy weather, resulting in severe soil erosion.

[0003] There are many types of existing restoration methods for abandoned mines, such as vegetation restoration. In one case, it is necessary to install hexagonal hollow slope protection bricks on the slope before planting vegetation. However, it is quite troublesome to install the hexagonal hollow slope protection bricks first and then plant vegetation because the slope area is large, planting is time-consuming and labor-intensive, and large-area sowing is easy to waste seeds. In addition, the seeds cannot be well placed in the center of each hexagon, making it difficult for them to survive later.

[0004] In the prior art, Chinese invention patent with publication number CN217284349U discloses a slope greening sprinkler irrigation device for ecological restoration, including a trolley, a fixed base, a horizontal pipe, a sprinkler pipe, a reciprocating screw, and a dial. This patent can use the sprinkler pipe to swing left and right and up and down intermittently to increase the sprinkler irrigation range for slope greening. However, this patent is not suitable for planting that requires the laying of hexagonal hollow slope protection bricks. If seeds are sprayed over a large area before the bricks are laid, the later growth of the seeds will break through the hexagonal hollow slope protection bricks, making the bricks unstable and loose, causing soil erosion and failing to achieve the purpose of slope protection.

Under the action of the cover opening motor 124, the bidirectional lead screw 125 is driven to rotate, thereby controlling the relative movement of the first sliding cover 126 and the second sliding cover 129 to close the hopper opening 112, or to move in the opposite direction to open the hopper opening 112.

[0035] An ecological restoration device for abandoned mine slopes, as described in the embodiments, Figure 1 , Figure 3 and Figure 6 As shown, the discharge mechanism includes a discharge motor 120 and a first discharge roller 127 and a second discharge roller 128 respectively disposed at the discharge ports of two compartments in the hopper 112. The discharge motor 120 is disposed on the frame 105 on the rear side of the hopper 112. The first discharge roller 127 and the second discharge roller 128 are respectively installed in two different accommodating spaces of the hopper 112, wherein the first discharge roller 127 is away from the discharge motor 120 and the second discharge roller 128 is close to the discharge motor 120. A first discharge pulley 113 is fixedly installed on the first discharge roller 127 and a second discharge pulley 114 is fixedly installed on the second discharge roller 128. The output shaft of the discharge motor 120 is provided with two sets of parallel pulleys. A second discharge belt 122 is sleeved between one pulley and the first discharge pulley 113, and a first discharge belt 121 is sleeved between the other pulley and the second discharge pulley 114. The first discharge roller 127 and the second discharge roller 128 are provided with two sets of discharge grooves symmetrically arranged on each other. Each set of discharge grooves includes four discharge grooves 130 arranged in a straight line.

[0036] Working principle of the invention: When using the invention, an auxiliary tractor can be added to assist the movement of the tractor's auxiliary frame 105. Seeds, fertilizers, or a viscous mixture of seeds and fertilizers are added to the hopper 112 in advance. Then, the motor on the moving wheel 109 is started. Under the action of the moving belt 110, the two moving wheels 109 rotate, moving the invention.

[0037] During the movement, the drive motor 104 is started, which drives the front axle 102 and cam 106 to rotate under the action of the front transmission belt 103 and the front pulley 101. When the cam 106 rotates, it cooperates with the digging shovel 107. When the digging shovel 107 is squeezed down, the large spring 135 connected to the digging shovel 107 is compressed. The digging shovel 107 digs four pits on the slope, and the excavated soil is thrown towards the parking position of the frame 105. When the cam 106 is no longer in contact with the digging shovel 107, the large spring 135 takes the digging shovel 107 back to its original position, and the frame 105 moves to the next position to dig pits. When the rear axle 115 rotates, it drives the crank 118 to rotate. The small pulley 134 on the crank 118 slides inside the slide frame 117, which in turn drives the slide frame 117 and the connecting rod 119 to slide up and down. When the slide frame 117 slides, it drives the covering shovel 116 to slide up and down. When the covering shovel 116 descends, it will penetrate into the soil and cover the pit with the soil piled up by the digging shovel 107, covering the seeds, fertilizer, etc. Because there are gaps between each tooth on the digging shovel 107 and the covering shovel 116, a clear pit shape will appear. After all the soil is placed together, the invention also climbs to the top of the slope. Then the invention moves to one side of the pit to place soil again until all the slopes are placed.

[0038] During operation, the present invention can also activate the angle cylinder 131 to extend its movable end according to the slope angle, causing the angle rack 132 to slide. The angle rack 132 meshes with the angle gear 133, causing the connecting shaft 123 and the hopper 112 to rotate, so that the opening at the lower end of the hopper 112 faces vertically downward. Then, the discharge motor 120 is started. Under the action of the pulley, the first discharge belt 121, the second discharge belt 122, the first discharge pulley 113, and the second discharge pulley 114, the first discharge roller 127 and the second discharge roller 128 are driven to rotate. When the first discharge roller 127 and the second discharge roller 128 rotate, seeds, fertilizers, or other materials are put into the dug pit through the discharge groove 130. Then, as the frame 105 continues to move, the rear axle 115 is driven to rotate under the action of the side pulley 108 and the side transmission belt 111.

[0039] After the seeds are sown in the trenches, the invention creates circular or square-shaped pits on the slope. This allows for the installation of hexagonal hollow slope protection bricks on the slope, securing each pit with the bricks. This facilitates maintenance, prevents soil erosion, and promotes seed growth.

[0040] Any aspects not covered in this invention are applicable to existing technologies.

[0041] The above description is merely one embodiment of the present invention, and while it is detailed and specific, it should not be construed as limiting the scope of the invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the appended claims.
