Description

Technical Field

[0001] The invention relates to the technical field of seedling cultivation, in particular to an ecological biological restoration structure suitable for desertified and degraded grasslands. Background Art

[0002] Grass grids are a common method used in ecological bioremediation of desertified grasslands. This method involves laying wheat seedlings and other grasses into grids on the sand. The grid-like netting effectively seals and stabilizes the sand. Planting greenery in the center of the grids also promotes their growth. Grass grids can be laid manually or by unmanned vehicles. The process involves placing the grass, rolling it, clearing the sand, and compacting it. Grass grids are laid vertically, followed by wheat seedlings, horizontally, to form a 1m x 1m sand barrier.

[0003] In the existing technology, the grass grid sand fixation technology has the following limitations: structural mechanics defects: the square grid has weak shear resistance in the diagonal direction, and the grid is prone to deformation and failure in areas with strong wind erosion; low space utilization: a single grid can only protect the central area, and the vegetation on the edge is easily threatened by secondary sand burial; construction efficiency bottleneck: existing machinery needs to be equipped with two sets of vertical and horizontal laying devices at the same time, the equipment is complex and the cost is high; material waste problem: vertical cross-laying causes the grass overlap rate to reach more than 30%, increasing material costs; single ecological function: simple grid structure is difficult to form a micro-ecosystem, and the water and fertilizer retention capacity is limited.

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0035] For example 1, please refer to Figures 1-10 An ecological bioremediation structure suitable for desertified and degraded grasslands includes an unmanned vehicle 100, a turntable 110 is rotatably provided on the unmanned vehicle 100, a first motor 120 is also provided on the unmanned vehicle 100, and the output shaft of the first motor 120 is connected to the center of the turntable 110, and a planting mechanism 200 and a flattening mechanism 300 are provided on the turntable 110, and the planting mechanism 200 and the flattening mechanism 300 are installed at an angle of 120°.

[0036] The planting mechanism 200 includes a forage box 210 and a grass inserting assembly 220 arranged on the turntable 110. The forage box 210 is arranged at an angle for holding wheat seedlings. The grass inserting assembly 220 includes an L-shaped fork 221. The flattening mechanism 300 includes a roller 310.

[0037] The wheat seedlings are clamped from the hay box 210 by the L-shaped fork 221 and planted in the sand. The turntable 110 is then driven by the first motor 120 to rotate 60° clockwise. The wheat seedlings are then flattened by the roller 310. Six wheat seedlings are planted to form a regular hexagonal sand barrier.

[0038] The unmanned vehicle 100 drives horizontally and plants five wheat seedlings in a circular motion to form the first row of regular hexagonal sand barriers. The unmanned vehicle 100 then turns around and plants four wheat seedlings to form a regular hexagonal sand barrier. The unmanned vehicle 100 continues to plant three wheat seedlings in a circular motion to form the second row of regular hexagonal sand barriers. The number of regular hexagonal sand barriers in the second row is one less than the number of regular hexagonal sand barriers in the first row. A honeycomb-shaped sand barrier knot is formed by several rows of regular hexagonal sand barriers.

[0039] In this embodiment, the unmanned vehicle 100 can be remotely controlled, facilitating operations in degraded grassland environments. A turntable 110 is rotatably mounted on the chassis of the unmanned vehicle 100. A forage bin 210 on the unmanned vehicle 100 can store a large amount of wheat seedlings. The detailed structure of the bin 210 can be referenced to existing rice transplanters and will not be described in detail here.

[0040] When it is set to the initial state, the front of the vehicle faces right, and the position of the turntable 110 makes the planting mechanism 200 distributed along the front-to-back direction, and the flattening mechanism 300 is distributed at an angle of 30° to the horizontal axis, so that the planting mechanism 200 and the flattening mechanism 300 form the left and lower left sides of a vertically placed regular hexagon.

[0041] Follow these steps to plant ecological restoration structures to maximize economic benefits:

[0042] S1, such as Figure 7 As shown, the unmanned vehicle 100 stops at this time, and controls the L-shaped fork 221 to make eccentric movement through the grass inserting component 220, and clamps a wheat seedling from the grass box 210 through its hook-shaped head and plants it in the sand, specifically at the location of the first planting point.

[0043] S2, such as Figure 7 As shown, the first motor 120 controls the turntable 110 to rotate 60° clockwise. The planting mechanism 200 is now positioned along the upper left edge of the regular hexagon, while the flattening mechanism 300 is positioned along the left edge of the regular hexagon. The planting mechanism 200 and the flattening mechanism 300 can now operate simultaneously, with the planting mechanism 200 planting a second wheat seedling at the second planting point. The flattening mechanism 300 controls the roller 310 to roll the first wheat seedling forward from the back, causing it to fall and sink into the sand, forming the left side of the regular hexagonal sand barrier.

[0044] S3, such as Figure 7 As shown, the first motor 120 controls the turntable 110 to continue rotating clockwise by 60°. At this time, the planting mechanism 200 and the flattening mechanism 300 operate simultaneously to plant the third wheat seedling and flatten the second wheat seedling. The second wheat seedling forms the upper left side of the regular hexagonal sand barrier. This cycle is repeated six times. In the last cycle, only the flattening mechanism 300 operates, and the planting mechanism 200 is controlled to suspend planting. Figure 7 The regular hexagonal sand barrier consists of six wheat seedlings.

[0045] S4, such as Figure 8 As shown, the dotted hexagonal structure represents the planted hexagonal sand barrier. Now control the unmanned vehicle 100 to drive a certain distance to the right and then stop. The first motor 120 controls the turntable 110 to rotate until the planting mechanism 200 is aligned with the upper left side of the regular hexagon, and repeat the above planting process. The second hexagonal sand barrier shares a side with the first hexagonal sand barrier. First, plant the upper left side of the second hexagonal sand barrier, and then plant the other four wheat seedlings in a clockwise direction to form the second hexagonal sand barrier. Repeat this process until a hexagonal sand barrier is formed. Figure 8 The first row of regular hexagonal sand barriers in the sand barrier. The number of the first row can be selected according to the specific plan of sand control, such as Figure 8 Choose from five.

[0046] S5, such as Figure 9As shown, unmanned vehicle 100 turns and prepares to drive left behind the first row of regular hexagonal sand barriers. Planting mechanism 200 and flattening mechanism 300 are controlled to their initial positions, and planting begins on the right side of the second row. The first regular hexagonal sand barrier in the second row shares two sides with the two rightmost regular hexagonal sand barriers in the first row. Planting the left side of the regular hexagon first, then planting the remaining three plants in a clockwise cycle, completes the first regular hexagonal sand barrier in the second row.

[0047] S6, such as Figure 9 As shown, the unmanned vehicle 100 drives to the left. At this time, the second regular hexagonal sand barrier in the second row shares three sides with the first regular hexagonal sand barrier in the second row and two regular hexagonal sand barriers in the first row. At this time, only three wheat seedlings need to be planted clockwise on the left, upper left, and upper right sides to form the second regular hexagonal sand barrier in the second row. This cycle continues to plant the second row of regular hexagonal sand barriers. The number of regular hexagonal sand barriers in the second row is reduced by one compared to the first row. Figure 9 There are four in the middle.

[0048] S7. Repeat the above steps to plant a third row of five regular hexagonal sand barriers. The first one on the left side of the third row shares one edge, and the second and following ones share three edges. Plant the fourth row, the fifth row, and so on, ultimately forming a honeycomb structure.

[0049] Compared to a square grid structure, this honeycomb structure is stronger and more wind-resistant, and the shared edges of the regular hexagons improve material utilization.

[0050] Example 2: This example is an improvement based on Example 1. For details, please refer to Figure 2-Figure 4 The grass inserting assembly 220 further includes a first rotating rod 222 and a first connecting arm 224 . The first rotating rod 222 is rotatably disposed on the turntable 110 , and a first connecting rod 223 is disposed at the tail end of the L-shaped fork 221 .

[0051] One end of the first connecting arm 224 is disposed on the first rotating rod 222 , and the other end of the first connecting arm 224 is rotatably connected to the first connecting rod 223 .

[0052] The grass inserting assembly 220 further includes a second rotating rod 225 , a second connecting arm 227 and a third connecting arm 228 . The second rotating rod 225 is rotatably disposed on the rotating disk 110 . A second connecting rod 226 is disposed in the middle of the L-shaped fork 221 .

[0053] One end of the second connecting arm 227 is disposed on the second rotating rod 225 , and the other end of the second connecting arm 227 is rotatably connected to the second connecting rod 226 . Both ends of the third connecting arm 228 are rotatably connected to the first connecting rod 223 and the second connecting rod 226 , respectively.

[0054] The planting mechanism 200 also includes a feeding assembly 230, which is used to transport the wheat seedlings on the forage box 210. The feeding assembly 230 includes a first conveying roller 231 and a second conveying roller 232 rotatably arranged on the forage box 210, and the first conveying roller 231 and the second conveying roller 232 are connected to a conveyor belt 233 for transmission.

[0055] The planting mechanism 200 further includes a first driving assembly 240 , which is used to drive the grass inserting assembly 220 and the feeding assembly 230 to operate.

[0056] The first driving assembly 240 includes a second motor 241 and a third motor 242 disposed on the turntable 110 . The output shaft of the second motor 241 is coaxially connected to the second rotating rod 225 , and the output shaft of the third motor 242 is coaxially connected to the second conveying roller 232 .

[0057] In this embodiment: a feeding assembly 230 is installed on the forage box 210 to assist the wheat seedlings to tilt and descend. The second conveyor roller 232 is driven by the third motor 242 to rotate clockwise, so that the first conveyor roller 231 and the conveyor belt 233 run clockwise, and the conveyor belt 233 circulates and transports the wheat seedlings in the forage box 210 downward.

[0058] The grass inserting assembly 220 is a linkage mechanism that performs eccentric motion. First, the second motor 241 drives the second rotating rod 225 to rotate counterclockwise, which in turn drives the second connecting arm 227 and the second connecting rod 226 to perform counterclockwise circular motion. The second connecting rod 226 then causes the L-shaped fork 221 to have a tendency to move in a circular motion. At the same time, because the first connecting rod 223 is limited by the first rotating rod 222 under the connection of the first connecting arm 224, the L-shaped fork 221 ultimately moves in an eccentric counterclockwise direction. Figure 3 For example, when L-shaped fork 221 moves counterclockwise from the upper point to the left, the head of L-shaped fork 221 tilts and contacts the forage on forage bin 210. When L-shaped fork 221 moves counterclockwise from the left point to the lower point, the head of L-shaped fork 221, carrying the forage, penetrates the ground in a nearly vertical direction. The planting mechanism 200, serving as the basic structure of a rice transplanter, is conventional, and the specific operating principle of L-shaped fork 221 will not be described in detail.

[0059] Example 3: This example is an improvement based on Example 1. For details, please refer to Figure 2-Figure 6 The flattening mechanism 300 also includes two bases 320 arranged parallel to the turntable 110, each of the two bases 320 is provided with a slide rail 330, each of the two slide rails 330 is provided with a slider 340 slidingly arranged, each of the two sliders 340 is provided with a mounting seat 350, a rotating shaft 360 is rotatably arranged on the mounting seat 350, and the roller 310 is provided on the rotating shaft 360.

[0060] The flattening mechanism 300 also includes a second drive assembly 370, which includes a fourth motor 371 arranged on the turntable 110, a screw rod 372 is rotatably arranged on the turntable 110, the output shaft of the fourth motor 371 is coaxially connected to the screw rod 372, and a nut 373 is provided on the mounting seat 350, and the nut 373 is threadedly connected to the screw rod 372.

[0061] The mounting seat 350 is slidably connected to the two sliders 340 . The two bases 320 are both provided with guide grooves 380 . Two guide rods 390 are symmetrically provided on the mounting seat 350 . The two guide rods 390 are slidably connected to the two guide grooves 380 , respectively.

[0062] In this embodiment: During flattening, Figure 6 For example, the guide slot 380 is horizontal at its top and bottom, tilted downward and forward at its rear, and tilted upward and forward at its front. First, the fourth motor 371 rotates the screw rod 372, causing the nut 373 and the mounting base 350 to move forward. The slider 340 then slides forward along the guide rail 330 along with the mounting base 350. During this forward movement, the guide rod 390 first moves along the rear oblique edge of the guide slot 380, causing the mounting base 350 to tilt downward and forward, allowing the roller 310 to contact the wheat seedlings and the ground.

[0063] The guide rod 390 then continues to move forward along the lower edge of the guide slot 380. The roller 310, under friction, rotates with the rotating shaft 360, pressing the wheat seedlings into the sand. Once the wheat seedlings are nearly completely embedded, the guide rod 390 tilts upward along the front edge of the guide slot 380, and the roller 310 leaves the ground. The fourth motor 371 is then controlled to operate in reverse, causing the screw rod 372 to rotate, causing the guide rod 390 to move backward along the upper edge of the guide slot 380, and the roller 310 to return to its original position.

[0064] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus.

[0065] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
