Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and in particular to a seeding device for ecological restoration of soil contaminated by uranium mines. Background Technology

[0002] During uranium mining, large amounts of radioactive materials are released into the soil, posing a serious threat to the ecological environment and human health. Therefore, the ecological restoration of uranium-contaminated soil is urgently needed. Currently, bioremediation, as a relatively effective remediation method, has received considerable attention in the treatment of uranium-contaminated soil, with planting plants such as paulownia and *Gnaphalium affine* (a type of uranium-rich plant) being an important approach.

[0003] However, current ecological restoration efforts face numerous challenges in the sowing stage: sowing primarily relies on manual planting, which is inefficient and slow. Furthermore, manual planting is physically demanding, requiring workers to bend or squat for extended periods, placing a heavy burden on their health in large uranium mine contaminated areas. Therefore, there is an urgent need to develop a specialized sowing device for the ecological restoration of uranium mine contaminated soil, to improve sowing efficiency, reduce labor intensity, and ensure the efficient implementation of ecological restoration work.

[0028] Example

[0029] Please see Figure 1-7 This utility model provides a seeding device for ecological restoration of soil contaminated in uranium mines, including a seeding box 1, a handle 2 on the upper part of the seeding box, a soil shoveling component on the lower part of the seeding box 1, and pull-out components on both sides of the seeding box 1. One end of the pull-out component is located below the handle 2, and the other end of the pull-out component is connected to the soil shoveling component. A seedling basket 3 is also provided on the seeding box 1 for placing seedlings.

[0030] The soil-shoveling assembly includes two symmetrically arranged digging shovels 4 below the seed box. A hinge block 5 is fixedly connected to each digging shovel 4, and a second hinge block 6 is fixedly connected to the seed box 1. Connecting sleeves 7 are alternately arranged on opposite sides of the second hinge block 6 and the first hinge block 5, and are connected to a rotating shaft 8. This structure allows the digging shovels 4 to rotate outwards around the rotating shaft 8. An interference fit is used between the rotating shaft 8 and the connecting sleeves 7 to prevent them from coming off. Two connecting blocks 9 are also provided on the outer side of the first hinge block 5, and a fixed shaft 10 is provided between the two connecting blocks 9. An annular groove 1001 is formed on the fixed shaft 10, and anti-slip patterns 1002 are provided inside the annular groove 1001. A traction rope 16 is tied in the annular groove 1001 to further limit the traction rope 16, preventing it from moving left or right and spreading out during sowing. The anti-slip patterns 1002 prevent the traction rope 16 from slipping and spreading out, thus affecting sowing efficiency.

[0031] The pull-out assembly includes two rotating blocks 11 located below the handle 2. The two rotating blocks 11 are connected to rotating rods 13 via pins 12. A mounting hole 131 is provided below the rotating rod 13, and a threaded rod 14 is threadedly connected to the mounting hole 131. A hanging ring 15 is fixedly connected to the end of the threaded rod 14. The hanging ring 15 is connected to one end of a traction rope 16, and the other end of the traction rope 16 passes through a storage cylinder 17 and is connected to a fixed shaft 10. The storage cylinder 17 is fixedly located on the side of the seed box 1. By pulling the rotating rods 13 upwards, the rotating rods 13 rotate along the pins 12, causing the traction rope 16 to pull upwards. The traction rope 16, through the fixed shaft 10, causes the two digging shovels 4 to open to both sides, allowing the seedlings to enter the soil.

[0032] In this embodiment, two seedling baskets 3 are provided, but one or more can be provided depending on the actual situation. A connecting hanging piece 18 is provided on the side of the seedling basket 3 that connects to the seeding box 1. A corresponding connecting hanging frame 19 is provided on the seeding box 1. The connecting hanging frame 19 and the connecting hanging piece 18 are compatible. The connecting hanging piece 18 is designed with an L-shaped structure, and the connecting hanging frame 19 is a box structure with an open top. The hanging method facilitates disassembly and cleaning of the seedling basket 3. The bottom of the seedling basket 3 is provided with multiple bottom plates 31. A gap is provided between two adjacent bottom plates 31. Some soil particles that fall from the seedling roots can fall into the soil through the gap between two bottom plates 31, avoiding the accumulation of a large amount of soil particles and increasing the weight and labor intensity.

[0033] The seeding box 1 includes a vertical section 101 and a tapering section. The length of the tapering section is set to one-quarter of the total length of the seeding box 1. The tapering section includes a front tapering section 102 and a rear tapering section 103. The rear tapering section 103 and the front tapering section 102 are connected by an arc-shaped inner wall 105. The arc transition reduces the impact of the sharp inner wall on the seedlings. The tapering angle of the front tapering section 102 is set to 10°, and the tapering angle of the rear tapering section 103 is set to 20°. Buffer layers 104 are provided on the side walls of both the vertical section 101 and the tapering section. The thickness of the buffer layers 104 is set to 1–1.2 cm. The front tapering section 102 guides the seedlings at a low speed with a small angle, which helps the seedlings enter smoothly and calibrate their posture, reducing damage to fragile root systems. The rear tapering section 103 accelerates the exit at a large angle, shortening the dwell time. Combined with the increasing thickness of the buffer layers, this reduces the impact force and protects the seedlings.

[0034] The specific connection methods of each part in this device all adopt conventional methods such as bolts, rivets, and welding that are mature in existing technology. The machinery and parts all adopt conventional models in existing technology, which will not be described in detail here.

[0035] In practical use, the user holds both handles 2 with both hands, inserts the digging shovel 4 below the seed box 1 into the soil, and simultaneously spreads their fingers to grip the rotating rod 13 and pulls it upward, causing the two digging shovels 4 to open. The seedling falls into the cleared pit. Then, the seed box 1 is lifted. During this process, the rotating rod 13 is slightly loosened but not completely released. As the two digging shovels 4 are lifted upward, they gradually half-close, burying the soil on both sides to the roots of the seedling. The above process is continued until sowing is complete.

[0036] Therefore, this utility model adopts the above-mentioned seeding device for ecological restoration of soil contaminated in uranium mines. Through the synergistic action of the shovel component and the pull component, the trenching and covering operations are completed simultaneously, replacing the manual process of digging pits and burying soil, improving work efficiency and reducing labor intensity. By pre-storing seedlings in multiple seedling baskets, there is no need to go back and forth to retrieve seedlings, thus improving seeding efficiency.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solution of this utility model, and these modifications or equivalent substitutions cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of this utility model.
