[0013] The present invention also discloses a method for laying a grass grid sand barrier for sand prevention and control, which adopts the above-mentioned grass grid sand barrier laying device for sand prevention and control, and comprises the following steps:

[0014] S1. First, when the grass roller needs to be reloaded after use, the first driving motor can be started, and the output end of the first driving motor drives the connecting shaft to drive the chain to rotate, so that the next group of rotating rollers moves to the designated position under the drive of the chain, thereby realizing the automatic loading of the grass roller, without the need for staff to stop the machine for operation, thereby improving the efficiency of subsequent grass grid sand barrier laying;

[0015] S2. When the grass roller is loaded to the specified position, the micro-electric push rod can be started, and the output end of the micro-electric push rod drives the docking rod to drive the docking block to move in the direction of the docking hole. When the docking block is aligned with the docking hole, the docking block is inserted into the docking hole to connect the docking rod with the rotating roller. When the docking block is misaligned with the docking hole, the docking rod squeezes the auxiliary spring during the movement. When the micro-electric push rod stops moving, the second drive motor is started, and the output end of the second drive motor drives the first bevel gear to rotate slowly, and then drives the rotating shaft to rotate in a circle through the first bevel gear, so that after the misaligned docking block is aligned with the docking hole, the docking block is bounced into the inner side of the docking hole under the action of the auxiliary spring, thereby connecting the rotating roller with the rotating shaft, so as to release the grass grid rolled up on the grass roller;

[0016] S3, when the docking rod moves toward the direction of the rotating roller, it drives the power rod to move, and when the power wheel contacts the inner inclined groove of the connecting column, it pushes the connecting column to drive the latch to move away from the third connecting plate, and when the docking rod stops moving, the latch moves out of the inner fixing hole of the third connecting plate, so that the third connecting plate is no longer fixed to the U-shaped vertical rod, so that the second connecting plate and the third connecting plate are separated from each other, thereby driving the first holding ring and the second holding ring to separate, so that the rotating shaft can drive the rotating roller to rotate to release the grass roller;

[0017] S4, when the docking rod moves toward the direction of the rotating roller, it drives the trapezoidal block to move synchronously, and the inner inclined surface of the trapezoidal block moves to the front of the spherical rod first, and then the power wheel contacts the inner inclined groove of the connecting column, so that when the rotating roller needs to be replaced, the docking rod drives the power wheel to move out of the inner inclined groove of the connecting column during the resetting process, and the inner inclined surface of the trapezoidal block contacts the spherical rod, and the spherical rod is pushed under the action of the inclined surface to drive the second holding ring to move downward, so that after the second holding ring presses the rotating roller, the fixing hole on the inner side of the third connecting plate is aligned with the latch, so that the latch is reset and stuck in the inner fixing hole of the third connecting plate under the action of the connecting spring, thereby fixing the second holding ring, so that the rotating roller will not fall off during the rotation process, thereby ensuring the smooth operation of the device, and thus improving the overall practicality of the device;

[0018] S5. When the docking rod drives the first connecting ring to move toward the rotating roller, the connecting rod pushes the spur rack to move toward the second spur gear, thereby driving one of the second spur gears to drive one of the pressure rollers to rotate toward the grass roller, and then driving another of the second spur gears to drive another of the pressure rollers to rotate synchronously toward the grass roller. When the docking rod stops moving, the two pressure rollers are attached to the position where the grass roller needs to be released, so as to limit the release position of the grass roller and avoid the release position of the grass roller from being offset after loading, thereby improving the stability of subsequent grass grid sand barrier laying.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. By setting up an automatic feeding mechanism, the output end of the first driving motor drives the connecting shaft to drive the chain to rotate, so that the next set of rotating rollers moves to the designated position under the drive of the chain, thereby realizing automatic feeding of grass rollers, without the need for staff to stop the machine for operation, thereby improving the efficiency of subsequent grass grid sand barrier laying;

[0021] 2. By setting a docking assistant, when the grass roller is loaded to the specified position, the micro-electric push rod can be started, and the output end of the micro-electric push rod drives the docking rod to drive the docking card block to move in the direction of the docking hole. When the docking card block is aligned with the docking hole, the docking card block is inserted into the docking hole to connect the docking rod with the rotating roller. When the docking card block is misaligned with the docking hole, the docking rod squeezes the auxiliary spring during the movement. When the micro-electric push rod stops moving, the second drive motor is started, and the output end of the second drive motor drives the second bevel gear to rotate slowly, and then drives the rotating shaft to rotate in a circle through the first bevel gear, so that after the misaligned docking card block is aligned with the docking hole, the docking card block is ejected into the inner side of the docking hole under the action of the auxiliary spring, thereby connecting the rotating roller with the rotating shaft, so as to release the grass grid rolled up on the grass roller;

[0022] 3. By arranging the cooperation of parts such as the trapezoidal block, when the docking rod moves toward the direction of the rotating roller, the trapezoidal block is driven to move synchronously. The inner inclined surface of the trapezoidal block moves to the front of the spherical rod first, and then the power wheel contacts the inner inclined groove of the connecting column. When the rotating roller needs to be replaced, the docking rod drives the power wheel to move out of the inner inclined groove of the connecting column during the resetting process. The inner inclined surface of the trapezoidal block contacts the spherical rod, and the spherical rod is pushed under the action of the inclined surface to drive the second holding ring to move downward. After the second holding ring presses the rotating roller, the fixing hole on the inner side of the third connecting plate is aligned with the latch, so that the latch is reset and clamped into the inner fixing hole of the third connecting plate under the action of the connecting spring, thereby fixing the second holding ring, so that the rotating roller will not fall off during the rotation process, thereby ensuring the stable operation of the device and improving the overall practicality of the device.

[0023] 4. By setting up auxiliary guiding parts, when the docking rod drives the first connecting ring to move in the direction of the rotating roller, the spur rack is pushed to move in the direction of the second spur gear through the connecting rod, thereby driving a second spur gear to drive a pressure roller to rotate in the direction of the grass roller, and then driving another second spur gear to drive another pressure roller to rotate synchronously in the direction of the grass roller. When the docking rod stops moving, the two pressure rollers are attached to the position where the grass roller needs to be released, so as to limit the release position of the grass roller and avoid the deviation of the release position of the grass roller after loading, thereby improving the stability of the subsequent grass grid sand barrier laying.

The auxiliary guide includes a support plate 5 fixedly connected to the inner side of the bracket 2. The top of the support plate 5 is rotatably connected to two rotating shafts 29. The outer walls of the two rotating shafts 29 are fixedly connected to a second spur gear 30 and an auxiliary seat 28. The two second spur gears 30 are meshed. The back of the auxiliary seat 28 is rotatably connected to a pressure roller 27. The auxiliary guide also includes a vertical plate 33 fixedly connected to the top of the support plate 5.

When the docking rod 23 stops moving, the two pressure rollers 27 are attached to the position where the grass roller 4 needs to be released, so as to limit the release position of the grass roller 4 and avoid the release position of the grass roller 4 from being offset after loading, thereby improving the stability of the subsequent grass grid sand barrier laying.

[0050] In combination with the above-mentioned straw grid sand barrier laying device for sand prevention and control, a method for laying a straw grid sand barrier for sand prevention and control is provided, which specifically includes the following steps:

[0051] S1. First, when the grass roller 4 is used up and needs to be reloaded, the first drive motor 14 can be started, and the output end of the first drive motor 14 drives the connecting shaft 13 to drive the chain 9 to rotate, so that the next group of rotating rollers 10 are driven by the chain 9 to move to the designated position, thereby realizing the automatic loading of the grass roller 4, without the need for the staff to stop the machine for operation, thereby improving the efficiency of the subsequent grass grid sand barrier laying;

[0052] S2. After the grass roller 4 is loaded to the specified position, the micro electric push rod 22 can be started. The output end of the micro electric push rod 22 drives the docking rod 23 to drive the docking block 36 to move toward the docking hole 46. When the docking block 36 is aligned with the docking hole 46, the docking block 36 is inserted into the docking hole 46 to connect the docking rod 23 with the rotating roller 10. When the docking block 36 is misaligned with the docking hole 46, the docking rod 23 squeezes the auxiliary spring 45 during the movement. When the micro electric push rod 22 stops moving, the second drive motor 19 is started. The output end of the second drive motor 19 drives the second bevel gear 20 to rotate slowly, and then drives the rotating shaft 17 to rotate in a circle through the first bevel gear 18, so that the misaligned docking block 36 is aligned with the docking hole 46. The docking block 36 is ejected into the inner side of the docking hole 46 under the action of the auxiliary spring 45, thereby connecting the rotating roller 10 with the rotating shaft 17, so as to release the grass grid rolled up on the grass roller 4.

[0053] S3, when the docking rod 23 moves toward the rotating roller 10, it drives the power rod 40 to move, and when the power wheel 41 contacts the inner oblique groove of the connecting column 42, it pushes the connecting column 42 to drive the latch 43 to move away from the third connecting plate 38. When the docking rod 23 stops moving, the latch 43 moves out of the inner fixing hole of the third connecting plate 38, so that the third connecting plate 38 is no longer fixed to the U-shaped vertical rod 39, so that the second connecting plate 37 and the third connecting plate 38 are separated from each other, thereby driving the first holding ring 15 and the second holding ring 16 to separate, so that the rotating shaft 17 can drive the rotating roller 10 to rotate to release the rolled grass grid on the grass roller 4;

[0054] S4, when the docking rod 23 moves toward the rotating roller 10, it drives the trapezoidal block 34 to move synchronously. The inner inclined surface of the trapezoidal block 34 moves to the front of the spherical rod 35 first, and then the power wheel 41 contacts the inner inclined groove of the connecting column 42. When the rotating roller 10 needs to be replaced, the docking rod 23 drives the power wheel 41 to move out of the inner inclined groove of the connecting column 42 during the resetting process. The inner inclined surface of the trapezoidal block 34 contacts the spherical rod 35, and the spherical rod 35 is pushed under the action of the inclined surface to drive the second holding ring 16 to move downward. After the second holding ring 16 presses the rotating roller 10, the fixing hole on the inner side of the third connecting plate 38 is aligned with the latch 43, so that the latch 43 is reset and stuck in the inner fixing hole of the third connecting plate 38 under the action of the connecting spring 44, thereby fixing the second holding ring 16, so that the rotating roller 10 will not fall off during the rotation process, thereby ensuring the smooth operation of the device and improving the overall practicality of the device.

[0055] S5. When the docking rod 23 drives the first connecting ring 24 to move toward the rotating roller 10, the spur rack 31 is pushed to move toward the second spur gear 30 through the connecting rod 26, thereby driving a second spur gear 30 to drive a pressure roller 27 to rotate toward the grass roller 4, and then driving another second spur gear 30 to drive another pressure roller 27 to rotate synchronously toward the grass roller 4. When the docking rod 23 stops moving, the two pressure rollers 27 are attached to the position where the grass roller 4 needs to be released, so as to limit the release position of the grass roller 4 and avoid the release position of the grass roller 4 from being offset after loading, thereby improving the stability of the subsequent grass grid sand barrier laying.

4. A method for laying a grass grid sand barrier for sand prevention and control, characterized in that: The straw grid sand barrier laying device for sand prevention and control as claimed in claim 3 comprises the following steps: S1. First, when the grass roller (4) is used and needs to be reloaded, the first drive motor (14) is started, and the output end of the first drive motor (14) drives the connecting shaft (13) to drive the chain (9) to rotate, so that the next group of rotating rollers (10) are driven by the chain (9) to move to a specified position, thereby realizing automatic loading of the grass roller (4) without the need for staff to stop the machine for operation, thereby improving the efficiency of subsequent grass grid sand barrier laying; S2. After the grass roller (4) is loaded to the designated position, the micro electric push rod (22) is started. The output end of the micro electric push rod (22) drives the docking rod (23) to drive the docking block (36) to move toward the docking hole (46). When the docking block (36) is aligned with the docking hole (46), the docking block (36) is inserted into the docking hole (46) to connect the docking rod (23) with the rotating roller (10). When the docking block (36) is misaligned with the docking hole (46), the docking rod (23) squeezes the auxiliary spring (45) during the movement. When the micro electric push rod (22) stops moving, the second drive motor (19) is started, and the output end of the second drive motor (19) drives the second bevel gear (20) to rotate slowly, thereby driving the rotating shaft (17) to rotate in a circle through the first bevel gear (18), so that the misaligned docking block (36) is aligned with the docking hole (46), and the docking block (36) is ejected into the inner side of the docking hole (46) under the action of the auxiliary spring (45), thereby connecting the rotating roller (10) with the rotating shaft (17), so as to release the rolled grass grid on the grass roller (4); S3, when the docking rod (23) moves toward the rotating roller (10), it drives the power rod (40) to move, and when the power wheel (41) contacts the inner inclined groove of the connecting column (42), it pushes the connecting column (42) to drive the latch (43) to move away from the third connecting plate (38), and when the docking rod (23) stops moving, the latch (43) moves out of the inner fixing hole of the third connecting plate (38), so that the third connecting plate (38) is no longer fixed to the U-shaped vertical rod (39), so that the second connecting plate (37) and the third connecting plate (38) move away from each other, thereby driving the first holding ring (15) and the second holding ring (16) to separate, so that the rotating shaft (17) can drive the rotating roller (10) to rotate to release the rolled grass grid on the grass roller (4); S4. When the docking rod (23) moves toward the rotating roller (10), it drives the trapezoidal block (34) to move synchronously. The inner inclined surface of the trapezoidal block (34) moves to the front of the spherical rod (35) before the power wheel (41) contacts the inner inclined groove of the connecting column (42). When the rotating roller (10) needs to be replaced, the docking rod (23) drives the power wheel (41) to move out of the inner inclined groove of the connecting column (42) during the resetting process. Then, the inner inclined surface of the trapezoidal block (34) contacts the spherical rod (35). The spherical rod (35) is pushed under the action of the connecting spring (44) to drive the second holding ring (16) to move downward, so that after the second holding ring (16) presses the rotating roller (10), the fixing hole on the inner side of the third connecting plate (38) is aligned with the latch (43), so that the latch (43) is reset and snapped into the fixing hole on the inner side of the third connecting plate (38) under the action of the connecting spring (44), thereby fixing the second holding ring (16) so that the rotating roller (10) will not fall off during the rotation process, thereby ensuring the smooth operation of the device and improving the overall practicality of the device; S5. When the docking rod (23) drives the first connecting ring (24) to move in the direction of the rotating roller (10), the connecting rod (26) pushes the spur rack (31) to move in the direction of the second spur gear (30), thereby driving one of the second spur gears (30) to drive one of the pressure rollers (27) to rotate in the direction of the grass roller (4), and then driving another of the second spur gears (30) to drive another of the pressure rollers (27) to rotate synchronously in the direction of the grass roller (4). When the docking rod (23) stops moving, the two pressure rollers (27) fit in the position where the grass roller (4) needs to be released, so as to limit the release position of the grass roller (4) and avoid the release position of the grass roller (4) from being offset after loading, thereby improving the stability of subsequent grass grid sand barrier laying.
