Description

Technical Field

[0001] This invention belongs to the field of windbreak and sand fixation technology, and in particular relates to a windbreak and sand fixation grass checkerboard laying machine. Background Technology

[0002] Desertification is one of the major environmental problems and natural disasters that threaten human survival. Long-term wind and sand erosion has constrained the ecological environment protection, construction, and social development in some areas. Therefore, wind and sand prevention and control is of utmost urgency.

[0003] Among engineering desertification control technologies, the most effective method is straw checkerboard sand fixation. Straw checkerboard sand barriers are an effective way for people to control land desertification and sandification. Straw checkerboards play an irreplaceable and important role in preventing wind erosion, fixing sand, intercepting precipitation, reducing water evaporation, and replenishing nutrients to sandy soil.

[0004] Currently, in desert ecological management and restoration, the stability of the straw checkerboard pattern is poor after the straw is laid on the sand.

[0005] To address the aforementioned issues, patent document CN217678987U discloses a straw checkerboard pressing device, comprising: a mobile vehicle and a rolling mechanism mounted on the mobile vehicle; the rolling mechanism includes: a rolling bracket extending through the mobile vehicle, an extension rod connected to the bottom surface of the rolling bracket, and a rolling sheet connected to and slidably connected to the bottom end of the extension rod. In use, this solution uses the rolling mechanism to compress the straw laid on the ground, embedding the straw into the sand to improve the stability of the straw checkerboard.

[0006] For example, patent document CN213978910U discloses a portable straw checkerboard laying device for desert control, which includes a base plate, a handle fixedly installed on one side of the base plate, the handle being inclined and U-shaped, three switches fixedly installed on the handle, four T-shaped rods inserted into the four corners of the top of the base plate, four fixing blocks fixedly connected to the bottom of the four T-shaped rods, four springs fitted on the four T-shaped rods, the top of the springs fixedly connected to the bottom of the base plate, the bottom of the springs fixedly connected to the top of the fixing blocks, and four fixing blocks installed at the bottom of the four fixing blocks. This device has two pressure plates, and a drive motor makes the two threaded sleeves move synchronously in opposite directions or close to each other, so that the two pressure plates press the straw.

[0007] For example, patent document CN115262518A discloses a grass checkerboard laying machine, including a chassis, a grass mat platform, a feeding mechanism, a cutting mechanism, and a rolling mechanism; the chassis has wheels to enable the grass checkerboard laying machine to move on its own or to facilitate its movement under the traction of a traction device; the grass mat platform is located above the chassis and is used to lay the grass mat on it; the feeding mechanism is used to lay the grass mat along the grass mat on the grass mat platform; the cutting mechanism is located above the grass mat platform and is used to cut the grass mat laid on the grass mat platform; the rolling mechanism is located above the grass mat platform and is used to press the cut grass mat into the sand.

[0008] The existing technology of grass checkerboard paving uses a single rolling mechanism to press the grass checkerboard paving material during installation. While this can improve the adhesion of the grass checkerboard paving to the sandy surface to some extent, it does not significantly improve the stability of the paving. As a result, the grass checkerboard paving material is still prone to shifting on the sandy ground, affecting the installation effect. Moreover, simply laying a single grass checkerboard paving material cannot effectively guarantee its windbreak and sand fixation effect. Summary of the Invention

[0009] The purpose of this invention is to provide a windbreak and sand-fixing grass checkerboard laying machine, which aims to solve the problem that the existing technology uses a single rolling mechanism to press the grass checkerboard material during laying, which does not significantly improve the stability of the grass checkerboard laying.

[0010] To achieve the above objectives, the present invention provides the following technical solution.

[0011] A windbreak and sand-fixing grass grid laying machine is used to lay grass rollers on sandy ground. The grass rollers include grass shafts and grass mats wound on the grass shafts.

[0012] The grass checkerboard laying machine includes a compaction mechanism, a seeding mechanism, and a soil covering mechanism, which are sequentially installed on the frame.

[0013] A pressing mechanism is used to press down the grass mat that has been released from the grass roller and laid on the sand to improve the adhesion of the grass mat to the sand surface.

[0014] A seeding mechanism for spreading grass seeds onto a grass mat surface laid on sand;

[0015] A soil covering mechanism is used to cover the surface of the grass mat after the grass seeds have been sown with soil.

[0016] In one embodiment of the present invention, the frame has an upper channel and a lower channel, wherein both the lower channel and the upper channel are inclined, and the inclined bottom end of the upper channel is connected to the inclined top end of the lower channel; and the connection point is connected to a window, which is opened on the frame.

[0017] Multiple sets of guide rollers are rotatably supported at the junction of the lower channel and the upper channel. The multiple sets of guide rollers form a receiving cavity for accommodating the straw rollers. The receiving cavity has an inlet channel that is inclined towards the bottom end of the upper channel, so that the straw rollers in the upper channel can enter the receiving cavity.

[0018] The receiving cavity has an outlet channel with its top inclined towards the lower channel. The width of the outlet channel is adapted to the grass shaft, so that when grass blanket is wound on the grass shaft, the grass roller will not enter the lower channel through the outlet channel; correspondingly, when the grass blanket on the grass shaft is released and only the grass shaft is left, the grass shaft is discharged through the outlet channel and collected in the lower channel.

[0019] The upper channel is supported by a rotatable material control shaft, which is equipped with a material control rod. The material control shaft is driven by a motor.

[0020] In one embodiment of the present invention, a set of drive rollers is included among the multiple sets of guide rollers. The rotation of the drive roller is driven by a second drive motor, so that when the drive roller rotates, it drives the grass roller located in the receiving cavity to rotate, so as to release the grass mat.

[0021] The drive roller is located at the bottom of the receiving cavity so that the grass roller is always in contact with the drive roller, which facilitates the release of the grass blanket by the rotating drive roller.

[0022] The window also has a guide roller to guide the grass carpet. After the grass carpet passes through the window, the end of the grass carpet touches the sand, and the pressing mechanism further presses the grass carpet on the sand to improve the adhesion of the grass carpet on the sand.

[0023] In one embodiment of the present invention, the grass checkerboard laying machine further includes:

[0024] The humidification mechanism is used to spray water onto the surface of the grass mat that passes through the window, so as to moisten the surface of the grass mat. This not only improves the adhesion of the grass mat to the sandy soil surface, but also makes it easier for the grass seeds sown on the grass mat by the seeding mechanism to survive.

[0025] The humidification mechanism includes:

[0026] A water tank is fixedly mounted on the frame and has a water supply pipe to replenish water to the tank when it is short of water.

[0027] The nozzle is located inside the window and faces the grass mat. A water pump is installed on the connecting pipe between the nozzle and the water tank. By starting the water pump, water in the water tank is pumped into the nozzle and sprayed out.

[0028] In one embodiment of the present invention, the grass checkerboard laying machine further includes:

[0029] The moving mechanism is used to realize the overall movement of the paving machine;

[0030] The moving mechanism includes:

[0031] A base plate, which is fixedly installed at the bottom of the frame;

[0032] The walking track is rotatably mounted on the base plate, enabling the overall movement of the paving machine.

[0033] In one embodiment of the present invention, the seeding mechanism includes:

[0034] The seed box is fixedly installed on the frame by a first bracket. The bottom of the seed box has a seed discharge pipe and a control valve is provided on the seed discharge pipe. By controlling the opening and closing of the control valve, the grass seeds in the seed box can be discharged.

[0035] A seed-spreading disc is fixedly installed below the seed box. Several seed-discharging grooves are evenly distributed around the seed-spreading disc. The bottom cavity of the seed-discharging groove has an inclined structure to facilitate the grass seeds in the seed-discharging groove to slide out.

[0036] The seed trough is coaxially arranged on the seed spreading disc, and the inclined tops of several seed outlet troughs are all connected to the seed trough. The seed trough is located below the seed discharge tube and is used to allow grass seeds in the seed box to fall into the seed trough when the seed discharge tube is in a conductive state.

[0037] A servo motor is fixedly installed on the bottom surface of the seeding disc. The output shaft of the servo motor rotates coaxially into the seed trough. Multiple arc-shaped levers are circumferentially installed on the output shaft of the servo motor located in the seed trough. The concave surface of the arc-shaped levers faces the opposite direction of rotation to the output shaft of the servo motor, so that the grass seeds in the seed trough can be pushed outward by the arc-shaped levers and evenly discharged through multiple seed discharge troughs, thereby achieving the effect of evenly distributing the seeds in the seed trough and evenly distributing the seeds on the grass mat.

[0038] In one embodiment of the present invention, the soil covering mechanism includes:

[0039] A sand box is fixedly mounted on a frame. A drive shaft is coaxially supported and rotatably mounted inside the sand box. A first drive motor for driving the drive shaft to rotate is mounted on the top of the sand box.

[0040] A soil spreading disc is rotatably mounted at the bottom opening of the sand box. The disc is coaxially and fixedly connected to the bottom end of the drive shaft, meaning that when the first drive motor drives the drive shaft to rotate, the spreading disc rotates synchronously. One side of the spreading disc also has a soil outlet. The upper surface of the spreading disc has an inclined structure, with the bottom end of the inclined structure abutting against the soil outlet, facilitating the discharge of sand from the spreading disc through the outlet. An annular groove is formed on the outer ring of the spreading disc, and an annular block that mates with the annular groove is fixedly installed at the bottom opening of the sand box to support the rotation of the spreading disc at the bottom opening of the sand box, improving stability.

[0041] In one embodiment of the present invention, the clamping mechanism includes:

[0042] The pressure roller is rotatably supported on the support plate, and the support plate is fixedly installed on the support block. The support block is provided with an internal thread groove.

[0043] An externally threaded rod is rotatably supported on a second bracket, which is fixedly mounted on the frame. The externally threaded rod is screwed into the internally threaded groove via a threaded connection.

[0044] Therefore, by rotating the external threaded rod, the height position of the support block relative to the external threaded rod can be adjusted according to the rotation direction of the external threaded rod, thereby adjusting the height position of the pressure roller relative to the frame, so as to adjust the depth of the pressing mechanism when rolling the straw mat.

[0045] In one embodiment of the invention, a guide rail groove is provided on the base plate, and the support block is slidably disposed in the guide rail groove to guide the movement of the support block in the vertical direction.

[0046] In one embodiment of the present invention, the grass checkerboard laying machine further includes:

[0047] The soil-taking mechanism is located at the front end of the frame. The soil-taking mechanism is used to take soil and transport the taken soil to the covering mechanism.

[0048] The soil extraction mechanism includes:

[0049] A sand shovel, which is supported and mounted on the machine head, which is fixedly mounted on the forward end of the frame;

[0050] The lifting chamber is located on the machine head and contains a lifting belt driven by a motor. Multiple lifting plates are evenly spaced along the lifting belt. A sand shovel is connected to the bottom of the lifting chamber via a sand channel, allowing sand to enter the lifting chamber through the sand channel when the sand shovel is shoveling. The sand is then lifted upwards by the lifting plates under the action of the rotating lifting belt.

[0051] In one embodiment of the present invention, the sand box and the top of the lifting cavity are connected by a conveying pipe, so that the sand lifted by the lifting plate is sent into the sand box through the conveying pipe.

[0052] The conveying pipe is also supported by a rotatable conveying shaft, on which a conveying propeller is mounted. The conveying shaft and the drive shaft are connected by gear meshing, so that when the soil spreading disc rotates to discharge sand, the conveying propeller rotates, so that the sand in the conveying pipe is continuously replenished into the sand box.

[0053] In this embodiment of the invention, a drive bevel gear is fixedly installed on the drive shaft, and a driven bevel gear that meshes with the drive bevel gear is provided at the end of the conveying shaft, so that when the first drive motor drives the drive shaft to rotate, it synchronously drives the conveying shaft to rotate, thereby replenishing sand into the sand box.

[0054] Compared with the prior art, in the specific implementation of the grass checkerboard laying machine provided by the present invention, the end of the grass mat is led out onto the sand. During the movement of the laying machine, the grass mat is continuously compressed by the pressing mechanism to improve the adhesion of the grass mat to the sand. The seeding mechanism is used to sow grass seeds, and the soil covering mechanism covers the grass mat with sand. The wetting mechanism keeps the surface of the grass mat moist, which is conducive to the survival of grass seeds. The soil taking mechanism takes soil from the front end of the laying machine in the forward direction, which can make the sand form a groove, so that the grass mat can be pressed into the groove by the pressing mechanism during the laying, thereby improving the stability of the grass mat after laying. The soil covering mechanism covers the grass mat with sand, which can further apply pressure to the grass mat, improve the stability of the grass mat, and the soil covering can also provide a soil environment for the grass seeds to survive. This effectively improves the effect of the grass checkerboard laying machine of the present invention in windbreak and sand fixation. Attached Figure Description

[0071] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0072] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0073] like Figure 1 As shown, in an embodiment of the present invention, a windbreak and sand-fixing grass grid laying machine is used to lay grass rollers 600 on sandy ground. The grass rollers 600 include grass shafts 602 and grass mats 601 wound on the grass shafts 602.

[0074] The grass checkerboard laying machine includes a pressing mechanism 700, a sowing mechanism 400, and a soil covering mechanism 500, which are sequentially installed on the frame 100.

[0075] A pressing mechanism 700 is used to press down the grass mat 601 that has been released by the grass roller 600 and laid on the sand to improve the adhesion of the grass mat 601 to the sand surface.

[0076] A seeding mechanism 400 is used to sow grass seeds onto the surface of a grass mat 601 laid on sand.

[0077] The soil covering mechanism 500 is used to cover the surface of the grass mat 601 after the grass seeds have been sown with soil.

[0078] Furthermore, such as Figures 1-2 As shown, in order to release the grass roller 600 so that the grass mat 601 can be spread on the sand, in this embodiment of the invention, the frame 100 has an upper channel 604 and a lower channel 603, wherein both the lower channel 603 and the upper channel 604 are inclined, and the inclined bottom end of the upper channel 604 communicates with the inclined top end of the lower channel 603; and the communication point communicates with the window 107, which is opened on the frame 100.

[0079] Furthermore, in this embodiment of the invention, a plurality of guide rollers 607 are rotatably supported at the junction of the lower channel 603 and the upper channel 604. The plurality of guide rollers 607 form a receiving cavity for accommodating the grass roller 600. The receiving cavity has an inlet roller channel 611 that is inclined towards the bottom end of the upper channel 604, so that the grass roller 600 in the upper channel 604 can enter the receiving cavity.

[0080] Furthermore, in this embodiment of the invention, the receiving cavity has an outlet channel 610 with its top inclined towards the lower channel 603. The width of the outlet channel 610 is adapted to the grass shaft 602, so that when the grass shaft 602 is wound with grass mat 601, the grass roller 600 will not enter the lower channel 603 through the outlet channel 610.

[0081] Correspondingly, when the grass mat 601 on the grass shaft 602 is completely released, leaving only the grass shaft 602, the grass shaft 602 is discharged through the shaft outlet channel 610 and collected in the lower channel 603.

[0082] Please continue reading with section 1- Figure 2 In this embodiment of the invention, one of the multiple sets of guide rollers 607 includes a set of drive rollers 608. The rotation of the drive roller 608 is driven by a second drive motor 609, so that when the drive roller 608 rotates, it drives the grass roller 600 located in the receiving cavity to rotate, so as to release the grass mat 601.

[0083] Preferably, in this embodiment of the invention, the drive roller 608 is located at the bottom of the receiving cavity, so that the grass roller 600 is always in contact with the drive roller 608, which facilitates the release of the grass mat 601 by the rotating drive roller 608.

[0084] Please continue reading. Figures 1-2 In this embodiment of the invention, the window 107 also has a guide roller 110 for guiding the grass mat 601. After the grass mat 601 passes through the window 107, the end of the grass mat 601 abuts against the sand, and the pressing mechanism 700 further presses down on the grass mat 601 on the sand to improve the adhesion effect of the grass mat 601 on the sand.

[0085] Preferably, in this embodiment of the invention, the guide roller 110 is also driven to rotate by a motor, so as to better pull the grass mat 601 and release the grass mat 601 on the grass roller 600.

[0086] Please continue reading. Figures 1-2 In this embodiment of the invention, the grass checkerboard laying machine further includes:

[0087] The wetting mechanism is used to spray water on the surface of the grass mat 601 that passes through the window 107 to wet the surface of the grass mat 601. This not only improves the adhesion of the grass mat 601 to the sandy soil surface, but also makes it easier for the grass seeds sown by the seeding mechanism 400 on the grass mat 601 to survive.

[0088] Preferably, in this embodiment of the invention, the wetting mechanism includes:

[0089] Water tank 300 is fixedly mounted on frame 100. Water tank 300 has water supply pipe 301 so that when water is insufficient in water tank 300, water can be supplied to water tank 300 through water supply pipe 301.

[0090] Nozzle 303 is located inside window 107 and faces the grass mat 601. A water pump 302 is installed on the connecting pipe between nozzle 303 and water tank 300. By starting water pump 302, water in water tank 300 is pumped into nozzle 303 and sprayed out.

[0091] For further information, please refer to [link / reference]. Figure 1 In this embodiment of the invention, the grass checkerboard laying machine further includes:

[0092] A moving mechanism is used to enable the overall movement of the paving machine.

[0093] Preferably, in this embodiment of the invention, the moving mechanism includes:

[0094] A base plate 108 is fixedly installed at the bottom of the frame 100;

[0095] The walking track 109 is rotatably mounted on the base plate 108, and the overall movement of the paving machine is achieved through the walking track 109.

[0096] It is understood that in the specific implementation of the grass checkerboard laying machine provided by this invention, after the grass roller 600 enters the receiving cavity, the end of the grass mat 601 is manually led out onto the sand. Then, the second drive motor 609 is started to drive the drive roller 608 to rotate, thereby driving the grass roller 600 to rotate and continuously release the grass mat 601. Then, when the grass checkerboard laying machine is started, during the movement of the laying machine, the pressing mechanism 700 continuously presses the grass mat 601 to improve the stability of the grass mat 601 in the sand. The grass shed has a good adhesion effect on the ground, and the seeding mechanism 400 is used to sow grass seeds, and the soil covering mechanism 500 covers the grass mat 601 with sand. The grass mat 601 is moist, which facilitates the survival of grass seeds. The soil covering the grass mat 601 can further apply pressure to the grass mat 601, improve the stability of the grass mat 601, and provide a soil environment for the grass seeds to survive. This effectively improves the grass checkerboard laying machine of the present invention in windbreak and sand fixation.

[0097] Furthermore, in this embodiment of the invention, in order to enable the grass rollers 600 in the upper channel 604 to enter the receiving cavity in sequence, a material control shaft 606 is rotatably supported on the upper channel 604, and a material control rod 605 is provided on the material control shaft 606. The material control shaft 606 is driven by a motor.

[0098] like Figure 1 , Figure 4 and Figure 5 As shown, in a specific implementation of the seeding mechanism 400 provided by the present invention, the seeding mechanism 400 includes:

[0099] Seed box 401 is supported and fixedly installed on frame 100 by first bracket 402. The bottom end of seed box 401 has seed discharge pipe 403. A control valve 404 is provided on seed discharge pipe 403. By controlling the opening and closing of control valve 404, grass seeds in seed box 401 can be discharged.

[0100] Furthermore, to improve the uniformity of seed dispersal after seed extrusion, in this embodiment of the invention, the seeding mechanism 400 further includes:

[0101] A seed-spreading disc 405 is fixedly installed below the seed box 401. Several seed-discharging grooves 406 are evenly distributed around the seed-spreading disc 405. The bottom cavity of the seed-discharging groove 406 has an inclined structure to facilitate the grass seeds in the seed-discharging groove 406 to slide out.

[0102] Seed trough 409 is coaxially arranged on the seed spreading disc 405, and the inclined top ends of several seed outlet troughs 406 are all connected to the seed trough 409. The seed trough 409 is located below the seed discharge tube 403 and is used to allow grass seeds in the seed box 401 to fall into the seed trough 409 when the seed discharge tube 403 is in the conductive state.

[0103] A servo motor 407 is fixedly installed on the bottom surface of the seeding disc 405. The output shaft of the servo motor 407 extends coaxially into the seed trough 409. Multiple arc-shaped levers 408 are circumferentially mounted on the output shaft of the servo motor 407 located in the seed trough 409. The arc-shaped concave surface of the levers 408 faces the opposite direction of rotation to the output shaft of the servo motor 407, so that the grass seeds in the seed trough 409 can be pushed outward by the arc-shaped levers 408 and evenly discharged through multiple seed discharge slots 406, thereby achieving the effect of evenly distributing the seeds in the seed trough 409, and thus evenly distributing the seeds on the straw mat 601.

[0104] Please continue reading. Figure 1 , Figure 6 and Figure 7 In an embodiment of the present invention, in a specific implementation of the soil covering mechanism 500 provided by the present invention, the soil covering mechanism 500 includes:

[0105] A sand box 501 is fixedly mounted on a frame 100. A drive shaft 502 is coaxially supported and rotatably mounted inside the sand box 501. A first drive motor 503 for driving the drive shaft 502 to rotate is mounted on the top of the sand box 501.

[0106] A soil spreading disc 505 is rotatably mounted at the bottom opening of the sand box 501. The soil spreading disc 505 is coaxially and fixedly connected to the bottom end of the drive shaft 502. That is, when the first drive motor 503 drives the drive shaft 502 to rotate, it drives the soil spreading disc 505 to rotate synchronously. The soil spreading disc 505 also has a soil outlet 506 on one side. The upper surface of the soil spreading disc 505 is an inclined surface structure, and the bottom end of the inclined surface structure abuts against the soil outlet 506, so that the sand on the soil spreading disc 505 can be discharged through the soil outlet 506.

[0107] In the specific implementation of the soil covering mechanism 500 provided by the present invention, the sand in the sand box 501 is discharged through the soil outlet 506. The first drive motor 503 further drives the soil spreading disc 505 to rotate, which can adjust the position of the soil outlet 506, that is, the position of the sand in the sand box 501 when it is discharged through the soil outlet 506. The position of the soil covering on the grass mat 601 can be adjusted as needed, which is flexible in use. When the soil spreading disc 505 rotates continuously, the sand discharged from the soil outlet 506 can cover more areas of the grass mat 601.

[0108] In addition, to achieve uniform soil covering, a soil-leveling roller can be installed at the bottom of the frame 100. After the soil covering mechanism 500 covers the grass mat 601 with soil, the soil-leveling roller will press the sand on the grass mat 601 evenly. This not only achieves uniform soil covering, but also makes the sand and grass seeds come into better contact, which is beneficial to the survival of the grass seeds.

[0109] Please continue reading. Figure 6 and Figure 7 In this embodiment of the invention, the outer ring of the soil spreading disc 505 is provided with an annular groove 507, and an annular block 508 that cooperates with the annular groove 507 is fixedly provided at the bottom opening of the sand box 501 to support the rotation of the soil spreading disc 505 at the bottom opening of the sand box 501 and improve stability.

[0110] like Figure 1 and Figure 3 As shown, in a specific implementation of the clamping mechanism 700 provided by the present invention, the clamping mechanism 700 includes:

[0111] The pressure roller 701 is rotatably supported on the support plate 702. The support plate 702 is fixedly installed on the support block 703. The support block 703 is provided with an internal thread groove 705.

[0112] An external threaded rod 706 is rotatably supported on a second bracket 704, which is fixedly installed on a frame 100. The external threaded rod 706 is screwed into the internal threaded groove 705 via a threaded connection.

[0113] Therefore, by rotating the external threaded rod 706, the height position of the support block 703 relative to the external threaded rod 706 can be adjusted according to the rotation direction of the external threaded rod 706, thereby adjusting the height position of the pressure roller 701 relative to the frame 100, so as to adjust the depth of the pressing mechanism 700 when rolling the straw mat 601.

[0114] In this embodiment of the invention, a guide rail groove 111 is provided on the base plate 108, and the support block 703 is slidably disposed in the guide rail groove 111 to guide the movement of the support block 703 in the vertical direction.

[0115] For further information, please refer to [link / reference]. Figure 1 In this embodiment of the invention, the grass checkerboard laying machine further includes:

[0116] A soil-taking mechanism is installed at the front end of the frame 100. The soil-taking mechanism is used to take soil and transport the taken soil to the covering mechanism 500.

[0117] Specifically, in this embodiment of the invention, the soil-taking mechanism includes:

[0118] A sand shovel 102 is supported and mounted on a machine head 101, which is fixedly mounted on the forward end of the frame 100.

[0119] A lifting chamber 103 is mounted on the machine head 101. A lifting belt 104 is installed inside the lifting chamber 103, and the operation of the lifting belt 104 is driven by a motor. Multiple sets of lifting plates 105 are evenly spaced on the lifting belt 104. The sand shovel 102 is connected to the bottom of the lifting chamber 103 through a sand channel 106, so that when the sand shovel 102 shovels soil, the sand enters the lifting chamber 103 through the sand channel 106, and then, under the action of the operating lifting belt 104, the sand entering the lifting chamber 103 is lifted upward by the lifting plates 105.

[0120] Furthermore, in this embodiment of the invention, the top of the sand box 501 and the lifting cavity 103 are connected by a conveying pipe 200, so that the sand lifted by the lifting plate 105 is sent into the sand box 501 through the conveying pipe 200.

[0121] Furthermore, such as Figure 1 and Figure 6 As shown, in this embodiment of the invention, a conveying shaft 202 is rotatably supported inside the conveying pipe 200. A conveying propeller 201 is provided on the conveying shaft 202. The conveying shaft 202 and the drive shaft 502 are connected by gear meshing so that when the soil spreading disc 505 rotates to discharge sand, the conveying propeller 201 rotates so that the sand in the conveying pipe 200 is continuously replenished into the sand box 501.

[0122] In this embodiment of the invention, a drive bevel gear 504 is fixedly installed on the drive shaft 502, and a driven bevel gear 203 that meshes with the drive bevel gear 504 is provided at the end of the conveying shaft 202, so that when the first drive motor 503 drives the drive shaft 502 to rotate, it synchronously drives the conveying shaft 202 to rotate, thereby replenishing sand into the sand box 501.

[0123] It is understood that the soil-taking mechanism in this invention takes soil from the front end of the laying machine in the forward direction, which can make the sand form a groove, so that the grass mat 601 can be pressed into the groove by the pressing mechanism 700 when it is laid, thereby improving the stability of the grass mat 601 after it is laid.

[0124] Although embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the specification and embodiments. It can be applied to various fields suitable for the present invention. Other modifications can be readily made by those skilled in the art. Therefore, without departing from the general concept defined by the claims and their equivalents, the present invention is not limited to the specific details and examples shown and described herein.
