Description

Technical Field

[0001] The present invention relates to the technical field of sand fixation and ecological restoration, and in particular to an assembled sand fixation structure for sand sealing and ecological restoration. Background Art

[0002] Planting windbreak and sand-fixing plants is the most effective way to restore the ecological environment of sandy areas. In addition to conventional planting methods, there's also a new method called straw grid planting. This method involves laying discarded wheat straw and other forage into grids on the sand. This grid-like netting effectively seals and fixes the sand. Planting plants in the center of the grid after laying the grids also promotes their growth.

[0003] Prior art still relies heavily on manual labor to lay out straw grids, requiring steps like placing, rolling, shoveling, and compacting the sand. The grids are laid vertically and then horizontally to create a 1m x 1m sand barrier. This method is not only inefficient but also extremely labor-intensive and economically inefficient.

[0004] Therefore, in order to solve the above technical problems existing in the prior art, an assembled sand-fixing structure for sand sealing and ecological restoration is proposed. Summary of the Invention

[0005] The present invention provides an assembled sand-fixing structure for sand sealing and ecological restoration. The structure has two sets of grass-inserting devices with an angle of 90 degrees installed on a sand vehicle. A row of grid-shaped grass can be laid out at one time by the vehicle's back-and-forth movement, which greatly improves the laying efficiency. It solves the problem that in the prior art mentioned in the above background technology, the laying of grass grids is still largely completed by manual labor. The operation requires the steps of placing, rolling grass, removing sand, and pressing sand. The grass is first laid longitudinally and then laid horizontally. Not only is the work efficiency low, but it is also extremely labor-intensive and has poor economic benefits.

[0029] 2. The assembled sand-fixing structure used for sand sealing and ecological restoration has two groups of horizontal grass-laying mechanisms arranged side by side in the front-to-back direction. First, the first grass-inserting component grabs two grasses and inserts their roots into the sand. Then, the two rear-drive wheels roll over them to flatten the two grasses horizontally on the sand.

DETAILED DESCRIPTION

[0040] 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.

[0041] For example 1, please refer to Figures 1-8 , an assembled sand-fixing structure for sand sealing and ecological restoration, comprising a dune buggy 100, the dune buggy 100 comprising a frame 110, the frame 110 being provided with rear-drive wheels 120 and front-drive wheels 130;

[0042] The frame 110 is also provided with a transverse grass-laying mechanism 200 and a longitudinal grass-laying mechanism 300. The transverse grass-laying mechanism 200 includes a grass box 210 provided on the frame 110, a first grass-inserting assembly 220, and a drive assembly 250. The grass box 210 is used to hold grass. The grass box 210 is arranged at an angle, and the lower end of the grass box 210 is open.

[0043] The first grass inserting assembly 220 includes an L-shaped fork 221. When the sand cart 100 moves laterally, the driving assembly 250 drives the L-shaped fork 221 to cyclically pick up the root of a grass from the grass box 210 and insert it into the sand, thereby laying the grass laterally.

[0044] The longitudinal grass-laying mechanism 300 has the same structure as the transverse grass-laying mechanism 200. The longitudinal grass-laying mechanism 300 is installed perpendicular to the transverse grass-laying mechanism 200. When the transverse grass-laying mechanism 200 lays grass in the transverse direction, the longitudinal grass-laying mechanism 300 lays grass in the longitudinal direction, thereby forming a grid-like grass sand barrier on the sand.

[0045] A sliding seat 140 and an electric push rod 150 are provided on the vehicle frame 110 along the front-to-back direction. The sliding seat 140 is slidably connected to the vehicle frame 110 , and the output shaft of the electric push rod 150 is connected to the sliding seat 140 ;

[0046] There are two transverse grass-laying mechanisms 200 and two longitudinal grass-laying mechanisms 300. The two transverse grass-laying mechanisms 200 are arranged side by side in the front-to-back direction, and the two longitudinal grass-laying mechanisms 300 are arranged in parallel in the front-to-back direction. The two longitudinal grass-laying mechanisms 300 are installed on the sliding seat 140.

[0047] The vehicle frame 110 alternately moves transversely from right to left, and then reverses direction to move transversely from right to left. During each movement, the two transverse grass-laying mechanisms 200 lay out two transverse strips of grass, and the two longitudinal grass-laying mechanisms 300 lay out a plurality of longitudinal strips of grass.

[0048] When the vehicle frame 110 is turned, the electric push rod 150 controls the longitudinal displacement of the sliding seat 140 and the two longitudinal paving mechanisms 300.

[0049] The frame 110 is further provided with a rotating shaft 160 , on which three rollers 170 are arranged side by side in the front-to-back direction. The three rollers 170 are respectively located at the front, middle, and rear sides of the frame 110 . The rotating shaft 160 is connected to the rear-drive wheels 120 via a first belt transmission device 180 .

[0050] The rear-drive wheels 120 are used to flatten the laterally laid hay, and the three rollers 170 are used to flatten the longitudinally laid hay.

[0051] In this embodiment, the dune buggy 100 is a vehicle specifically used for traveling on sandy ground. The dune buggy 100 can be driven by electricity or fuel. Figure 1 As shown, the head of the frame 110 is placed to the left, and the front-drive wheel 130 installed at its left end can be composed of two front-drive wheels, a front axle, etc., and the front-drive wheel 130 installed at its right end can be composed of two rear-drive wheels, a rear axle, etc.

[0052] A rotating shaft 160 is rotatably mounted to the right side of the rear-drive wheel 120. Three rollers 170 are mounted on the rotating shaft 160, front and rear. From front to back, they are the front roller 170, the front rear-drive wheel, the middle roller 170, the rear rear-drive wheel, and the rear rear-drive wheel. Furthermore, a sliding seat 140 is slidably mounted on the vehicle frame 110 in the forward and backward directions.

[0053] In the initial state, one of the two longitudinal grass-laying mechanisms 300 installed on the sliding seat 140 is located in the middle of the frame 110 , and the other is located at a position on the left side of the head relative to the frame 110 .

[0054] Abandoned wheat straw or other grass for laying the grass grid can be placed in the grass box 210 and the corresponding structure in the longitudinal grass laying mechanism 300. The L-shaped fork 221 installed on the left side of the grass box 210 is in a broken line shape, and the head at its right end is in a fork shape for hooking the root of the grass.

[0055] like Figure 8 As shown, during one travel direction, the vehicle frame 110 faces leftward and moves transversely from right to left. During travel, the two L-shaped forks 221 first hook the roots of a grass plant from the two grass boxes 210 and carry the two grass plants into the sand. The two L-shaped forks 221 then separate from the two grass plants. Then, as the two rear drive wheels 120 move to the left, they press the two transverse grass plants into the sand.

[0056] At the same time, the structures corresponding to the L-shaped forks 221 in the two longitudinal grass-laying mechanisms 300 will also insert the two grasses into the sand. When the three first belt transmission devices 180 pass by, the two longitudinal grasses will be pressed into the sand. Figure 8 The topmost paving shape.

[0057] Then the frame 110 continues to move to the left and lays horizontally and longitudinally to form Figure 8 Middle paving shape.

[0058] Then the frame 110 turns around, turns half a circle to the front, and faces right. Then the frame 110 moves to the right. At this time, the electric push rod 150 controls the displacement of the sliding seat 140, so that the two longitudinal grass laying mechanisms 300 are located in the middle of the frame 110 and the other is located on the right side relative to the head of the frame 110. When the frame 110 moves to the right, the horizontal and vertical laying is carried out, and a Figure 8 The paving shape of the lower middle side.

[0059] This process can be repeated to form a large grid composed of squares according to the paving plan.

[0060] Example 2: This example is an improvement based on Example 1. For details, please refer to Figures 1-6 , a first rotating rod 222 is rotatably provided on the frame 110 , and a first connecting rod 223 is provided at the tail end of the L-shaped fork 221 ;

[0061] The first grass inserting assembly 220 further includes a first connecting arm 224 , 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 ;

[0062] A second rotating rod 225 is rotatably provided on the vehicle frame 110 , and a second connecting rod 226 is provided in the middle of the L-shaped fork 221 ;

[0063] The first grass inserting assembly 220 further includes a second connecting arm 227 and a third connecting arm 228. 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.

[0064] In this embodiment, the first grass inserting assembly 220 is a connecting rod mechanism that performs eccentric motion. The second rotating rod 225 rotates clockwise to drive the second connecting arm 227 and the second connecting rod 226 to perform clockwise circular motion, and the second connecting rod 226 in turn causes the L-shaped fork 221 to generate a tendency to perform circular motion.

[0065] At the same time, the first connecting rod 223, connected to the first connecting arm 224, is restrained by the first rotating rod 222, ultimately causing the L-shaped fork 221 to move eccentrically in a clockwise direction. As it moves clockwise from the upper point to the right, the head of the L-shaped fork 221 tilts and contacts the hay in the hay bin 210. Furthermore, as the L-shaped fork 221 moves clockwise from the right point to the lower point, the head of the L-shaped fork 221, carrying the hay, penetrates the ground in a nearly vertical direction.

[0066] Example 3: This example is an improvement made on the basis of Example 2. For details, please refer to Figures 1-6The horizontal grass laying mechanism 200 further includes a second grass inserting assembly 230, which includes an inclined slot 231 provided on the vehicle frame 110, and a straight fork 232 is slidably provided in the inclined slot 231;

[0067] After the L-shaped fork 221 inserts the root of the grass into the sand, the straight fork 232 is tilted downward to insert the head of the grass into the sand.

[0068] A third rotating rod 233 is rotatably provided on the vehicle frame 110 , a rotating disk 234 is provided on the third rotating rod 233 , a third connecting rod 235 is provided on the rotating disk 234 at a position deviated from the center, and a fourth connecting rod 237 is provided on the straight fork 232 ;

[0069] The second grass inserting assembly 230 further includes a fourth connecting arm 236 , and both ends of the fourth connecting arm 236 are rotatably connected to the third connecting rod 235 and the fourth connecting rod 237 , respectively.

[0070] In this embodiment, when the grass is laid manually, the roots of the grass are first inserted into the ground, and then the grass is gradually flattened in the horizontal or vertical direction.

[0071] In this device, when the grass is flattened only by the rear drive wheels 120 and the rollers 170, the direction of the grass may be skewed. In particular, the grass inserted into the ground by the longitudinal paving mechanism 300 is in a vertical direction. When the rollers 170 roll from right to left, it is difficult to maintain the longitudinal shape and be flattened.

[0072] Therefore, a second grass inserting assembly 230 is provided, which drives the turntable 234 to rotate clockwise by the third rotating rod 233, and the third connecting rod 235 to make a clockwise circular motion, and drives the straight fork 232 to make a reciprocating linear motion in the inclined groove 231 through the transmission of the fourth connecting arm 236 and the fourth connecting rod 237.

[0073] like Figure 6 As shown, the straight fork 232 is located to the left of the L-shaped fork 221. When the straight fork 232 is tilted and displaced to the lower left, it will align with the position near the head of the grass and push it onto the sand, and insert the head of the grass into the sand. This allows the roots and heads of the horizontally laid grass to be pressed into the sand before the rear drive wheel 120 passes over them.

[0074] Similarly, the second grass inserting assembly 230 in the longitudinal grass laying mechanism 300 is tilted downward and forward, so that the head of the longitudinally laid grass can be inserted forward into the sand, so that the roots and heads of the longitudinally laid grass are pressed longitudinally into the sand before the roller 170 passes over them.

[0075] The longitudinal paving mechanism 300 is different from the transverse paving mechanism 200 in that the L-shaped fork 221 and the straight fork 232 in the transverse paving mechanism 200 are on the same horizontal line in the left-right direction, while Figure 7 As shown in FIG, the position of the straight fork 232 in the longitudinal paving mechanism 300 is further left than the position of the L-shaped fork 221. This corresponds to the displacement of the frame 110 when traveling to the left.

[0076] Example 4: This example is an improvement made on the basis of Example 3. For details, please refer to Figures 1-6 A feeding assembly 240 is provided on the feed box 210. The feeding assembly 240 includes a first conveying roller 241 and a second conveying roller 242 rotatably provided on the feed box 210. A conveyor belt 243 is provided on the first conveying roller 241 and the second conveying roller 242. The conveyor belt 243 is used to assist the feed in the feed box 210 to fall.

[0077] In this embodiment, in order to assist the hay in the hay box 210 to fall, an area is hollowed out in the middle thereof, and a conveyor belt 243 is installed in the area. The conveyor belt 243 is driven to rotate counterclockwise by the first conveyor roller 241 and the second conveyor roller 242.

[0078] Example 5: This example is an improvement made on the basis of Example 4. For details, please refer to Figure 1-Figure 7 The transverse paving mechanism 200 further includes a driving assembly 250, which includes a motor 251 disposed on the frame 110, and an output shaft of the motor 251 and the first conveying roller 241 are connected to each other through a second belt transmission device 252;

[0079] The driving assembly 250 also includes a fourth rotating rod 253 rotatably arranged on the frame 110. The first conveying roller 241 and the fourth rotating rod 253 are connected by a third belt transmission device 254. Gears 255 are provided on the fourth rotating rod 253 and the second rotating rod 225. The two gears 255 are engaged. The second rotating rod 225 and the third rotating rod 233 are connected by a fourth belt transmission device 256.

[0080] In this embodiment, the motor 251 drives the first conveying roller 241 to rotate counterclockwise through the second belt transmission device 252, thereby driving the feeding assembly 240 to operate.

[0081] The first conveying roller 241 drives the fourth rotating rod 253 to rotate counterclockwise via the third belt transmission device 254 , and the fourth rotating rod 253 drives the second rotating rod 225 to rotate clockwise via two gears 255 , thereby driving the driving assembly 250 to operate.

[0082] The second rotating rod 225 drives the third rotating rod 233 to rotate clockwise through the fourth belt transmission device 256, thereby driving the second grass inserting assembly 230 to operate.

[0083] The two first conveying rollers 241, the two second rotating rods 225, and the two third rotating rods 233 of the transverse paving mechanism 200 are coaxially connected. The two sets of transverse paving mechanisms 200 are driven by only one set of driving assembly 250. The two sets of longitudinal paving mechanisms 300 are driven by two sets of motors.

[0084] It should be noted that each of the aforementioned belt drive devices can be composed of two pulleys and a transmission belt. As a conventional technical approach, their specific structures are not described in detail. Furthermore, the transmission ratios of the belt drive devices can be adjusted to adjust the operating speeds of the first grass inserting assembly 220, the second grass inserting assembly 230, and the feeding assembly 240 to coordinate the laying of the grass.

[0085] 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.

[0086] 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.
