[0022] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0023] The sand barrier laying device of this invention includes a frame 100, a walking unit 200, a longitudinal laying unit 300, and a transverse laying unit 400. The walking unit 200 is connected to the bottom of the frame 100. The longitudinal laying unit 300 is installed at the front end of the frame 100 in the traveling direction. The longitudinal laying unit 300 includes a first support component 1 and a first laying component 2. The first support component 1 is used to support a first grass roll 500. The first laying component 2 is used to unfold the first grass roll 500 along the traveling direction of the frame 100 and lay it on the ground. In the traveling direction of the frame 100, the transverse laying unit 400 is installed downstream of the longitudinal laying unit 300. The transverse laying unit 400 includes a second support component 3 and a second laying component 4. The second support component 3 is used to support a second grass roll 600. The second laying component 4 is used to unfold the second grass roll 600 along the orthogonal direction of the traveling direction of the frame 100 and lay it on the ground.

[0024] Specifically, such as Figure 1 and Figure 2 As shown, the walking unit 200 is located at the bottom of the frame 100, the longitudinal laying unit 300 is located at the front end of the frame 100, and the transverse laying unit 400 is located at the rear end of the longitudinal laying unit 300.

[0025] The first laying component 2 is located behind the first support component 1. The first grass roll 500 is placed on the first support component 1 and is placed in the left-right direction. The first laying component 2 lays the first grass roll 500 in the front-back direction.

[0026] The second grass roll 600 is placed on the second support member 3, and the second grass roll 600 is placed in the front-to-back direction. The second paving assembly is located below the second support member 3, and the second paving assembly lays the second grass roll 600 in the left-to-right direction.

[0027] It should be noted that when the frame 100 is pulled forward by the traction equipment, the longitudinal laying unit 300 lays the first straw roll 500 in the front-to-back direction and presses it into the ground, and the transverse laying unit 400 lays the second straw roll 600 in the left-to-right direction and presses it into the ground.

[0028] The sand barrier laying device of this utility model can simultaneously lay the meadow longitudinally and laterally by setting up a longitudinal laying unit 300 and a transverse laying unit 400. Imagine that the laying equipment in the related technology first completes the longitudinal laying, then turns the front of the vehicle to the transverse direction, and then lays along the transverse direction. However, the laying device of this application can simultaneously lay the meadow longitudinally and laterally by using the longitudinal laying unit 300 and the transverse laying unit 400. Compared with the longitudinal and transverse laying in the related technology, it improves the laying quality and efficiency of grass checkerboard sand barriers.

[0029] In some embodiments, the first support member 1 includes a pair of upper support rollers 11 and a pair of lower support rollers 12, with the upper support rollers 11 located above the lower support rollers 12. The pair of upper support rollers 11 and the pair of lower support rollers 12 are spaced apart in the traveling direction of the frame 100 to form a support space, and the first straw roll 500 is placed in the support space.

[0030] Specifically, such as Figure 2 As shown, a pair of upper support rollers 11 are arranged opposite each other in the front-to-back direction and parallel to each other in the left-to-right direction. A lower support roller 12 is located below the upper support rollers 11, and a pair of lower support rollers 12 are arranged opposite each other in the front-to-back direction and parallel to each other in the left-to-right direction. The pair of upper support rollers 11 and the pair of lower support rollers 12 form a support space similar to a V-shape, and the first straw roll 500 is placed in the support space.

[0031] By setting up two upper support rollers 11 and two lower support rollers 12 to form a support space, it is convenient to place the first straw roll 500 and improve the laying efficiency of the sand barrier.

[0032] In some embodiments, the first laying assembly 2 includes a first feeding roller 21 and a first pressing component 22. In the traveling direction of the frame 100, the first feeding roller 21 is located downstream of the first support component 1, and the first pressing component 22 is located downstream of the first feeding roller 21. The first pressing component 22 is used to press grass into the ground.

[0033] Specifically, such as Figure 1 and Figure 2 As shown, the first feeding roller 21 is located behind the first support member 1. There are two first feeding rollers 21. The two first feeding rollers 21 are arranged at intervals in the front-to-back direction and are arranged parallel to each other in the left-to-right direction. The first straw roll 500 is inserted into the gap between the two first feeding rollers 21 and the outer surface of the first feeding roller 21 is in contact with the first straw roll 500. When the two first feeding rollers 21 rotate relative to each other, the straw mat is conveyed to the ground by the friction between the feeding roller and the straw roll.

[0034] The first straw pressing component 22 is located behind the first support component 1. The first straw pressing component 22 presses the straw mat laid on the ground into the ground.

[0035] In some embodiments, the first grass-pressing component 22 includes a first telescopic member 221, a first elastic member 222, a first support frame 223, and a grass-pressing wheel 224. The fixed end of the first telescopic member 221 is connected to the frame 100, the telescopic end of the first telescopic member 221 is connected to one end of the first elastic member 222, the other end of the first elastic member 222 is connected to the first support frame 223, the grass-pressing wheel 224 is connected to the first support frame 223, the grass-pressing wheel 224 is rotatable relative to the first support frame 223, and the rotation axis of the grass-pressing wheel 224 is arranged along the width direction of the frame 100.

[0036] Specifically, such as Figure 3 As shown, the upper end of the first telescopic member 221 is connected to the frame 100, the lower end of the first telescopic member 221 is connected to the first elastic member 222, the lower end of the first elastic member 222 is connected to the first support frame 223, and a grass-pressing wheel 224 is installed at the lower end of the first support frame 223. The grass-pressing wheel 224 is rotatable relative to the first support frame 223, and the outer periphery of the grass-pressing wheel 224 has grass-pressing blades, the width of which is smaller than the width of other parts of the grass-pressing wheel 224. For example, the first telescopic member 221 can be a hydraulic cylinder or a pneumatic cylinder.

[0037] The height of the first support frame 223 can be adjusted by setting the first telescopic component 221. The first elastic component 222 can not only play a buffering role, but also ensure that the grass pressing wheel 224 is always in contact with the ground, ensuring that the grass pressing wheel 224 presses the grass mat into the ground.

[0038] In some embodiments, there are multiple first grass-pressing components 22, and the multiple first grass-pressing components 22 are arranged at intervals along the width direction of the frame 100.

[0039] For example, there can be two first grass-pressing components 22, which are arranged opposite each other in the left and right direction, forming two longitudinal grass strips.

[0040] Optionally, the spacing between the two first straw pressing components 22 in the left-right direction is adjustable, thereby adapting to straw grating laying operations of different widths.

[0041] In some embodiments, the second laying assembly 4 includes a second feeding component 41 and a second pressing component 42. The second feeding component 41 includes a second feeding roller 411 and a spreading component 412. The second feeding roller 411 is located below the second support component 3, and the axis of the second feeding roller 411 extends along the length direction of the frame 100. The spreading component 412 is located below the second feeding roller 411, and the spreading component 412 unfolds the second grass roll 600 along the width direction of the frame 100.

[0042] Specifically, such as Figure 4 As shown, the second feeding roller 411 is located below the second support member 3. There are two second feeding rollers 411, which are arranged at intervals in the left-right direction and parallel to each other in the front-back direction. The second straw roll 600 is inserted into the gap between the two second feeding rollers 411, and the outer surface of the second feeding roller 411 is in contact with the second straw roll 600. When the two second feeding rollers 411 rotate relative to each other, the straw mat is conveyed to the ground by the friction between the feeding roller and the straw roll.

[0043] The spreading component 412 is located below the second feeding roller 411. The spreading component 412 extends in the left and right direction and spreads the straw mat conveyed by the second feeding roller 411 in the left and right direction.

[0044] In some embodiments, the paving component 412 includes two paving conveyor belts 4121 that extend along the width direction of the frame 100 and are spaced apart along the length direction of the frame 100.

[0045] Specifically, such as Figure 4 As shown, two paving conveyor belts 4121 are arranged at intervals along the front-to-back direction. By setting up two paving conveyor belts 4121, the efficiency and flatness of the straw mat can be improved, ensuring the efficiency and quality of the lateral laying of the straw mat.

[0046] In some embodiments, the second grass pressing component 42 includes a second telescopic member 421, a blade holder 422, and a grass pressing blade 423. The fixed end of the second telescopic member 421 is connected to the frame 100, and the telescopic end of the second telescopic member 421 is connected to the blade holder 422. The grass pressing blade 423 is detachably mounted on the blade holder 422 and is located between two paving conveyor belts 4121.

[0047] Specifically, such as Figure 1 and Figure 4 As shown, the upper end of the second telescopic member 421 is connected to the frame 100, and the lower end of the second telescopic member 421 is connected to the blade holder 422. The blade holder 422 extends in the left and right direction and is located between the two paving conveyor belts 4121. In other words, the blade holder 422 is located between the intervals of the two paving conveyor belts 4121. The grass pressing blade 423 is detachably installed on the blade holder 422. There are multiple grass pressing blades 423, and the multiple grass pressing blades 423 are evenly spaced in the left and right direction.

[0048] The lower end of the straw-pressing knife 423 has serrations, and the second telescopic component 421 can be a cylinder. The cylinder drives the straw-pressing knife 423 to move up and down. Since the lower end of the straw-pressing knife 423 has serrations, the serrations can cut the straw.

[0049] In some embodiments, the second laying assembly 4 further includes a grass-cutting component 43, which is located between the second feed roller 411 and the spreading component 412 in the height direction of the frame 100. The grass-cutting component 43 includes a guide rail 431, a cutter 432, a second elastic member 433, and a reciprocating drive component 434. The guide rail 431 is connected to the frame 100 and extends along the width direction of the frame 100. The cutter 432 is located inside the guide rail 431 and is movable in the width direction of the frame 100. The second elastic member 433 is located inside the guide rail 431, and one end of the second elastic member 433 is connected to the cutter 432. The other end of the second elastic member 433 is connected to the inner wall surface of the guide rail 431. The reciprocating drive component 434 is connected to the cutter 432 to drive the cutter 432 to reciprocate in the width direction of the frame 100.

[0050] Specifically, such as Figure 4 and Figure 5 As shown, the guide rail 431 extends in the left-right direction and has a guide groove inside. The cutter 432 extends in the front-back direction and the front and rear ends of the cutter 432 are separately installed in the guide rails 431 on the front and back sides. The cutter 432 can reciprocate in the left-right direction. There are two second elastic elements 433, which are respectively installed in the front and back guide rails 431. The reciprocating drive component 434 is connected to the cutter 432 and can drive the cutter 432 to reciprocate in the left-right direction.

[0051] For example, the reciprocating drive component 434 can be a reciprocating cylinder. In some embodiments, the walking unit 200 includes two track 8 walking components, which are arranged opposite to each other in the width direction of the frame 100.

[0052] Specifically, such as Figure 6 As shown, the track 8 traveling component includes two traveling wheels 5, with the track 8 wrapped around the outside of the two traveling wheels 5. The housing 7 is located inside the traveling wheels 5, and the drive mechanism 6 is installed inside the housing 7. The drive component includes a motor, a drive gear, and a driven gear. The motor is connected to the drive gear, the driven gear meshes with the drive gear, and the driven gear is connected to the shaft of the traveling wheel 5.

[0053] The two track 8 traveling components are arranged opposite each other in the left and right directions. By controlling the speed of the motors in the left and right track 8 traveling components, the turning of the entire paving device can be achieved.

[0054] The following reference Figures 1 to 6 Describe the operation process of the sand barrier laying device of this utility model.

[0055] The first grass roll 500 is placed on the first support component 1. One end of the first grass roll 500 passes between the two first feeding rollers 21. When the two first feeding rollers 21 rotate, they drive one end of the first grass roll 500 to move downwards and move forward in conjunction with the entire frame 100, so as to realize the laying of grass mat in the front-to-back direction. The pressure of the grass pressing wheel 224 is used to press the grass mat into the ground to realize the laying of longitudinal grass strip.

[0056] The second grass roll 600 is placed on the second support member 3, with one end of the second grass roll 600 passing between the two second feeding rollers 411. When the two second feeding rollers 411 rotate, they drive one end of the second grass roll 600 downwards, passing through one side of the cutting edge of the cutter 432. Due to the reciprocating drive member 434 driving the cutter 432 to reciprocate in the left-right direction at a frequency, the second grass roll 600 can be cut into a fixed length, and the grass mat is spread out in the left-right direction using two spreading conveyor belts 4121. The second telescopic member 421 is activated, driving the grass pressing blade 423 downwards, pressing the grass mat on the spreading conveyor belt 4121 into the ground to achieve the laying of the transverse grass strips. Finally, the transverse and longitudinal grass strips form a grass grid sand barrier.
