[0002] Planting wind-proof and sand-fixing green plants is the most effective means to repair the ecological environment of sandy land. In addition to the conventional green plant planting method, there is also a new grass grid planting method. The grass grid planting method is to lay abandoned wheat straw and other grass materials on the sand into squares. The square-shaped grass net can play a good role in sealing and fixing sand. After laying the grass grid, planting green plants in the center of the grid is also conducive to the growth of green plants.

[0003] In the prior art, the laying of grass grids is still largely done by manual labor, which requires steps such as placing, rolling grass, shoveling sand, and pressing sand. The sand is first laid longitudinally and then horizontally to form a 1m×1m sand barrier. This laying method is not only inefficient, but also extremely labor-intensive and has poor economic benefits.

DETAILED DESCRIPTION

[0028] 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.

[0029] For example, see Figure 1-Figure 8 , an assembled sand-fixing structure for sand sealing and ecological restoration, comprising a sand car 100, the sand car 100 comprising a frame 110, and the frame 110 is provided with rear-drive wheels 120 and front-drive wheels 130; 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, a first grass inserting assembly 220 and a driving assembly 250 provided on the frame 110. The grass box 210 is used to hold grass. The grass box 210 is arranged in an inclined manner, and the lower end of the grass box 210 is open. The first grass inserting assembly 220 includes an L-shaped fork 221. When the sand cart 100 moves transversely, 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 transversely. The structure of the longitudinal grass laying mechanism 300 is consistent with that of the transverse grass laying mechanism 200. The installation direction of the longitudinal grass laying mechanism 300 is perpendicular to that of the transverse grass laying mechanism 200. When the transverse grass laying mechanism 200 lays grass laterally, the longitudinal grass laying mechanism 300 lays grass longitudinally, thereby forming a grid-shaped grass sand barrier on the sand. A sliding seat 140 and an electric push rod 150 are provided on the vehicle frame 110 along the front-rear 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 ; 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, the two longitudinal grass-laying mechanisms 300 are arranged in parallel in the front-to-back direction, and the two longitudinal grass-laying mechanisms 300 are installed on the sliding seat 140; The vehicle frame 110 alternately moves transversely from right to left, and then turns around to move transversely from right to left. During each movement, the two transverse grass laying mechanisms 200 lay out two transverse grass strips, and the two longitudinal grass laying mechanisms 300 lay out a plurality of longitudinal grass strips. When the frame 110 is turned, the electric push rod 150 controls the longitudinal displacement of the sliding seat 140 and the two longitudinal grass-laying mechanisms 300; The frame 110 is also provided with a rotating shaft 160, and three rollers 170 are arranged side by side on the rotating shaft 160 along the front-to-back direction. The three rollers 170 are respectively located at the front side, the middle side and the rear side of the frame 110. The rotating shaft 160 is connected to the rear-drive wheel 120 through a first belt transmission device 180. The rear-drive wheels 120 are used to flatten the transversely laid hay, and the three rollers 170 are used to flatten the longitudinally laid hay.

[0030] In this embodiment, the sand car 100 is a vehicle specially used for traveling on sand. The sand car 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.

[0031] A rotating shaft 160 is also rotatably mounted on the right side of the rear drive wheel 120, and three rollers 170 are mounted on the rotating shaft 160, which 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. In addition, a sliding seat 140 is also slidably mounted on the frame 110 along the front-to-back direction.

[0032] 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 .

[0033] Abandoned wheat straw or other forage for laying the grass grid can be placed in the forage 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 forage box 210 is in a broken line shape, and the head at the right end is in a fork shape for hooking the root of the forage.

[0034] like Figure 8 As shown, in one traveling direction, the frame 110 moves horizontally from right to left with its head facing left. During the traveling process, the two L-shaped forks 221 first hook the root of a grass from the two grass boxes 210, and carry the two grasses into the sand, and then the two L-shaped forks 221 separate from the two grasses. Then, when the two rear drive wheels 120 move to the left, the two horizontal grasses are pressed into the sand.

[0035] 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.

[0036] Then the frame 110 continues to move to the left and lays horizontally and longitudinally to form Figure 8 Middle paving shape.

[0037] Then the frame 110 turns around and turns half a circle to the front, with the head facing right. Then the frame 110 moves to the right, and the electric push rod 150 controls the displacement of the sliding seat 140, so that one of the two longitudinal grass laying mechanisms 300 is 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 longitudinal laying is performed, and a Figure 8 The laying shape of the lower middle side.

[0038] This process can be repeated to form a large grid composed of squares according to the laying plan.

[0039] Embodiment 2: This embodiment is an improvement on Embodiment 1. For details, please refer to Figure 1-Figure 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; 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; A second rotating rod 225 is rotatably disposed on the vehicle frame 110, and a second connecting rod 226 is disposed in the middle of the L-shaped fork 221; 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.

[0040] In this embodiment, the first grass inserting component 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 further causes the L-shaped fork 221 to generate a tendency to perform circular motion.

[0041] At the same time, the first connecting rod 223 is limited by the first rotating rod 222 under the connection of the first connecting arm 224, and finally the L-shaped fork 221 moves eccentrically in the clockwise direction. When it moves clockwise from the upper point to the right point, the head of the L-shaped fork 221 is inclined to contact the grass on the grass box 210. When the L-shaped fork 221 moves clockwise from the right point to the lower point, the head of the L-shaped fork 221 carries the grass and inserts it into the ground in a nearly vertical direction.

[0042] Embodiment 3: This embodiment is an improvement on Embodiment 2. For details, please refer to Figure 1-Figure 6 The transverse grass laying mechanism 200 further includes a second grass inserting assembly 230, and the second grass inserting assembly 230 includes an inclined groove 231 provided on the frame 110, and a straight fork 232 is slidably disposed in the inclined groove 231; 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; 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 deviating from the center of the circle, and a fourth connecting rod 237 is provided on the straight fork 232; The second grass inserting assembly 230 further includes a fourth connecting arm 236 , and two ends of the fourth connecting arm 236 are rotatably connected to the third connecting rod 235 and the fourth connecting rod 237 , respectively.

[0043] In this embodiment, when the grass is laid manually, the root of the grass is first inserted into the ground, and then the grass is gradually flattened in the horizontal or vertical direction.

[0044] In this device, when the grass is flattened only by the rear drive wheel 120 and the roller 170, the direction of the grass may be skewed. In particular, the grass inserted into the ground by the longitudinal paving mechanism 300 is vertical, and it is difficult to keep the longitudinal shape and be flattened when the roller 170 rolls from right to left.

[0045] Therefore, a second grass inserting assembly 230 is provided, and the third rotating rod 233 rotates clockwise to drive the rotating disk 234 to rotate, and the third connecting rod 235 performs clockwise circular motion, and the fourth connecting arm 236 and the fourth connecting rod 237 drive the straight fork 232 to perform reciprocating linear motion in the inclined groove 231.

[0046] like Figure 6 As shown, the straight fork 232 is located on the left side of the L-shaped fork 221. When the straight fork 232 is tilted and displaced to the lower left, it will be aligned with the position near the head of the grass to push it down on the sand, and the head of the grass will be inserted into the sand, so that the root and head of the grass laid horizontally are pressed into the sand in the horizontal direction before the rear drive wheel 120 passes over it.

[0047] Similarly, the second grass inserting assembly 230 in the longitudinal grass laying mechanism 300 is tilted and displaced toward the front and downward, so that the head of the longitudinally laid grass can be inserted into the sand toward the front, so that the root and head of the longitudinally laid grass are pressed into the sand along the longitudinal direction before the roller 170 passes over.

[0048] 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. 1 , the position of the straight fork 232 in the longitudinal paving mechanism 300 is to the left of the position of the L-shaped fork 221. This can correspond to the displacement of the frame 110 when traveling to the left.

[0049] Embodiment 4: This embodiment is an improvement on Embodiment 3. For details, please refer to Figure 1-Figure 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.

[0050] In this embodiment, in order to assist the forage in the forage 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 run by the first conveyor roller 241 and the second conveyor roller 242 to rotate in the counterclockwise direction.

[0051] Embodiment 5: This embodiment is an improvement made on the basis of Embodiment 4. For details, please refer to Figure 1-Figure 7 The transverse paving mechanism 200 further includes a driving assembly 250, the driving assembly 250 includes a motor 251 disposed on the frame 110, and the output shaft of the motor 251 and the first conveying roller 241 are connected in transmission via a second belt transmission device 252; 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 in transmission via a third belt transmission device 254, the fourth rotating rod 253 and the second rotating rod 225 are both provided with gears 255, the two gears 255 are meshed, and the second rotating rod 225 and the third rotating rod 233 are connected in transmission via a fourth belt transmission device 256.

[0052] 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.

[0053] The first conveying roller 241 drives the fourth rotating rod 253 to rotate counterclockwise through the third belt transmission device 254 , and the fourth rotating rod 253 drives the second rotating rod 225 to rotate clockwise through two gears 255 , thereby driving the driving assembly 250 to operate.

[0054] 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 component 230 to operate.

[0055] The two first conveying rollers 241 in the transverse grass-laying mechanism 200 are coaxially connected, the two second rotating rods 225 are coaxially connected, and the two third rotating rods 233 are coaxially connected. The two sets of transverse grass-laying mechanisms 200 are driven by only one set of driving components 250. The two sets of longitudinal grass-laying mechanisms 300 are driven by two sets of motors.

[0056] It should be supplemented that each of the above-mentioned belt transmission devices can be composed of two pulleys and a transmission belt. As a conventional technical means, its specific structure is not described in detail. And the running speed of the first grass inserting component 220, the second grass inserting component 230, and the feeding component 240 can be achieved by adjusting the transmission ratio of each belt transmission device to cooperate with the laying of grass.

[0057] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0058] 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 the scope of protection of the present invention.
