[0034] Embodiment

[0035] Combined with Figures 1 to 8 As shown, this embodiment provides an intelligent fully automatic grass-laying trolley, including a movable vehicle body 10, and further including: a feeding mechanism 20, a material-grabbing mechanism 30, a material-spreading mechanism 40, a pressing-in mechanism 50, a compaction mechanism 60, a transmission mechanism 31 and a control system arranged on the vehicle body 10, and the control system is connected to the material-grabbing mechanism 30, the material-spreading mechanism 40, the pressing-in mechanism 50 and the compaction mechanism 60; wherein, the feeding mechanism 20 is used for placing materials; the material-grabbing mechanism 30 is connected to the feeding mechanism 20 and is adapted to grab the materials in the feeding mechanism 20 onto the material-spreading mechanism 40; the material-spreading mechanism 40 is used for conveying the materials to the spreading opening 43; the pressing-in mechanism 50 is arranged at the bottom of the vehicle body 10 and is located behind the spreading opening 43 along the advancing direction of the vehicle body 10, and is used for pressing the materials into the sand to a certain depth; the compaction mechanism 60 is arranged behind the pressing-in mechanism 50 along the advancing direction of the vehicle body 10 and is used for burying and compacting the materials pressed into the ground.

[0036] Combined with Figures 1 to 3As shown, in this embodiment, the vehicle body 10 includes a housing, a chassis 11 and wheels. Above the chassis 11 are provided with a feeding mechanism 20, a material grabbing mechanism 30, a material spreading mechanism 40, a pressing-in mechanism 50, a compaction mechanism 60, a transmission mechanism 31 and a control system. And a material spreading opening 43 is provided on the chassis 11. Above the feeding mechanism 20, the housing is provided with a feeding opening 12, and the feeding opening 12 is provided with a switch door 13, and the switch door 13 can be opened and closed in a flip-up manner. The material can be common sand spreading materials such as wheat straw.

[0037] Combined with Figures 2 to 4 As shown, the feeding mechanism 20 includes an arc-shaped bin 21 and a cam mechanism 22. An outlet is provided at the connection between the arc-shaped bin 21 and the material grabbing mechanism 30. The cam mechanism 22 includes a cam 221 and a pressing plate 222. The pressing plate 222 is adapted to press the material towards the outlet. Here, the cam 221 and the pressing plate 222 are connected by a connecting bar, and the connecting bar is connected to one side of the cam 221. A gap suitable for the sliding of the connecting bar is provided above the arc-shaped bin 21. When filling the material grass, first turn the pressing plate 222 away from the inside of the arc-shaped bin 21, and then put down the pressing plate 222 after filling the material, so that the material can be pressed down by the pressing plate 222 to prevent the material from getting stuck inside the bin. Here, the pressing plate 222 rotates around a fixed point inside the arc-shaped bin 21 under the action of the gravity of the cam 221, without the need to additionally increase a driving device, and the structure is simple and practical.

[0038] Combined with Figures 2 to 5 As shown, in this embodiment, the material grabbing mechanism 30 includes a transmission mechanism 31 and a grabbing wheel 33. The transmission mechanism 31 includes a rotating motor 311. The grabbing wheel 33 is connected to the rotating motor 311 through a conveyor belt and a pulley. The rotating motor 311 is adapted to drive the grabbing wheel 33 to rotate counterclockwise. A plurality of clamping claws 34 are provided on the grabbing wheel 33. The clamping claws 34 are adapted to enter the feeding mechanism 20 when the grabbing wheel 33 rotates to grab the material onto the material spreading mechanism 40. Here, the rotating motor 311 is fixed on the chassis 11. The pulley is at the same height as the center of the grabbing wheel 33, and the rotating motor 311, the pulley and the grabbing wheel 33 are all connected by a belt to drive the grabbing wheel 33 to move. Here, the pulley functions to change the direction and adjust the rotation speed. Preferably, two grabbing wheels 33 are arranged in parallel, and a plurality of the clamping claws 34 are evenly arranged on the two grabbing wheels 33.

[0039] Combined with Figure 5As shown, the grasping wheel 33 is arranged above the chassis 11 through a bracket 32. The grasping wheel 33 includes a fixed disk 331 and a rotating wheel 332. The fixed disk 331 and the rotating wheel 332 can rotate relative to each other. An irregularly shaped chute 3311 is arranged on the fixed disk 331, and the fixed disk 331 is eccentrically arranged on the bracket 32. The clamping jaws 34 are movably arranged on the rotating wheel 332 and are distributed along the circumference of the rotating wheel 332. The clamping jaws 34 include two clamping pieces 342 and a support rod 341. The clamping pieces 342 are rotatably arranged on the support rod 341. A limiting block 343 is arranged between the clamping pieces 342 and the rotating wheel 332 to limit the clamping jaws 34 on the rotating wheel 332. A cylindrical joint is arranged at one end of the support rod 341 away from the clamping piece 342. The cylindrical joint is installed in the chute 3311. When the rotating wheel 332 is driven by a belt to rotate, the clamping jaws 34 can rotate with the rotating wheel 332. At the same time, the cylindrical joint of the support rod 341 slides in the chute 3311, enabling the support rod 341 to expand and contract on the rotating wheel 332. When expanding and contracting, the two clamping pieces 342 arranged on the support rod 341 are controlled to rotate, thereby achieving the opening and closing actions, that is, the clamping and releasing actions. Here, the belt is connected to the grasping wheel 33 through a bearing. The rotating part of the bearing is connected to the rotating wheel 332 and is at the same center position as the rotating wheel 332, enabling the belt to drive the rotating wheel 332 to rotate around the center of the rotating wheel 332. The position of the chute 3311 is set such that when the clamping jaws 34 pass through the discharge port, they are just in the process of opening to closing to realize material grasping, and when reaching above the material spreading mechanism 40, the clamping jaws 34 open to release the material. Through this setting, the clamping action is optimized. The clamping is realized through a mechanical connection method, replacing the high cost of using a cylinder to drive the clamping jaws 34 to clamp.

[0040] Combined with Figure 6As shown, the material spreading mechanism 40 includes a conveyor belt device and a material spreading opening 43. The conveyor belt device includes a first conveyor belt 41 horizontally arranged below the material grasping mechanism 30 and a second conveyor belt 42 inclinedly arranged on the chassis 11 of the vehicle body 10. A material spreading opening 43 is arranged on the chassis 11 of the vehicle body 10, and one end of the second conveyor belt 42 is close to the first conveyor belt, and the other end extends out of the material spreading opening 43 and extends below the chassis 11. Here, a motor is arranged on the chassis 11, and the motor is used to drive the conveyor belt to rotate. Baffles are arranged on both sides of the conveyor belt to prevent materials from falling out from the side of the conveyor belt. In a preferred embodiment, the second conveyor belt 42 can also be arranged as two conveyor belts with opposite rotations, and a gap for materials to pass through is arranged between them. The inlet of the gap is flush with the end of the first conveyor belt 41, which is convenient for materials to enter the gap between the second conveyor belts 42 from the first conveyor belt 41. Through this setting, the materials can be pressed when entering the second conveyor belt 42. At the same time, due to the increase in the frictional force above and below, the materials are also easier to be driven by the conveyor belt, so that the materials will not accumulate at the material spreading opening 43.

[0041] Combined with Figure 7As shown, the pressing mechanism 50 is arranged behind the material spreading opening 43 along the moving direction of the vehicle body 10. It includes a disc 51 and a first driving rod 52. The disc 51 is rotatably arranged below the vehicle body 10 and is adapted to press the materials falling from the material spreading opening 43 into the ground. The first driving rod 52 connects the disc 51 and the vehicle body 10 and is adapted to adjust the pressing height of the disc 51. Here, the disc 51 is connected below the chassis 11 of the vehicle body 10 through a connecting frame 53, and the connecting frame 53 can rotate by a certain angle on the chassis 11. The first driving rod 52 connects the connecting frame 53 and can control the ground clearance of the disc 51 by driving the rotation amplitude of the connecting frame 53. The first driving rod 52 can be a telescopic cylinder or a linear motor and is inclinedly arranged on the vehicle body 10. The disc 51 can rotate on the connecting frame 53 so that it can rotate when pressing the materials to reduce the frictional force of the vehicle body 10. In a preferred embodiment, a first sensor is arranged on the pressing mechanism 50. The first sensor is adapted to detect the depth of the disc 51 pressing into the ground, and the control system is adapted to control the first driving rod 52 to adjust the height of the disc 51 according to the signal of the first sensor. Here, the first sensor can use an infrared sensor, and the control system can use a single-chip microcomputer system and is connected to the control system of the whole vehicle body 10. Here, by adjusting the angle of the disc 51, it can be ensured that the depth of the materials pressed into the sandy soil is between 10 - 15 cm. Through the combination of the control system, the sensor and the adjustment of the angle of the disc 51, the accurate adjustment of the depth of the materials pressed into the sandy soil is realized, and it is always maintained in a dynamic balance, thereby greatly improving the sand fixation quality and extending the sand fixation life, and solving the problem of uneven and inconsistent manual laying.

[0042] Combined with Figure 8As shown, the compaction mechanism 60 is arranged behind the pressing-in mechanism 50 along the moving direction of the vehicle body 10. It includes a second driving rod 61 and a soil covering plate 62 arranged on the vehicle body 10. One end of the second driving rod 61 is connected to the two soil covering plates 62 and is configured to drive the two soil covering plates 62 to approach and move away from each other, so as to compact the sand on the material pressed into the ground by the pressing-in mechanism 50. Here, there are two soil covering plates 62, which are rotatably fixed on a fixing frame 63. The fixing frame 63 is fixed under the chassis 11 of the vehicle body 10. The two soil covering plates 62 are connected to the second driving rod 61 through two sliding rods 64, and there is a certain angle between the two sliding rods 64. The second driving rod 61 can be a telescopic cylinder, which is rotatably arranged on the vehicle body 10 and is connected to one end of the two sliding rods 64 through a connecting block 65. When the second driving rod 61 expands and contracts, it can drive the sliding rods 64 to move horizontally, and at the same time, the connecting block 65 rotates. When the sliding rods 64 approach each other, they drive the soil covering plates 62 to approach each other, so as to gather the sand and make the sand accumulate and bury on the material pressed by the pressing-in mechanism 50. Here, the central position between the two soil covering plates 62 is in a straight line with the disc 51, so that the soil covering plates 62 can accurately bury the sand on the material. In a preferred embodiment, the compaction mechanism 60 further includes a second sensor. The second sensor can be an infrared sensor and is arranged above the bracket 32. The control system is adapted to control the second driving rod 61 to adjust the opening and closing angle of the soil covering plate 62 according to the signal of the second sensor. In another preferred embodiment, each soil covering plate 62 includes two soil covering pieces, and the soil covering pieces are arranged in an arc shape, and the two soil covering pieces can rotate by a certain angle. In this embodiment, after the soil covering plate 62 in the compaction mechanism 60 contacts the gully pressed out by the pressing-in mechanism 50, the electric rod in the compaction mechanism 60 drives the two soil covering plates 62 to open and close according to a certain rule. At the same time, a sensor is also arranged on the compaction mechanism 60. According to the data transmitted by the sensor, the second driving rod 61 is used to adjust the covering angle and strength of the soil covering plate 62, achieving the effect of compacting the sand.

[0043] In this embodiment, the first driving rod 52, the second driving rod 61, the sensor, the motor, etc. are all electrically connected to the control system. The control system includes a single-chip microcomputer system, etc., and can be coordinately controlled by implanting an operation program.

[0044] The working principle of the present invention is as follows: Before the device works, the operator puts the neatly arranged materials into the arc-shaped bin 21 of the feeding mechanism 20. Due to the gravity of the pressing plate 222, the neatly arranged materials will be pressed tightly. There is a discharge port at the lower rear of the bin for the material grabbing mechanism 30 to grab. The material grabbing mechanism 30 drives the counterclockwise rotation through the transmission mechanism 31. At the discharge port, the clamping jaws 34 close to grab the material. When the material grabbing mechanism 30 rotates to the designated position, the clamping jaws 34 open, and the material falls onto the first conveyor belt 41 in the material spreading mechanism 40 under the action of gravity. The first conveyor belt 41 drives the material to be conveyed forward to the entrance of the second conveyor belt 42, and then the conveyor belt in the opposite direction conveys the material into the spreading port 43 and falls onto the sand surface. After the material falls onto the sand surface, the entire device moves forward. When the pressing mechanism 50 touches the laid material, the control system calculates the depth of the device sinking into the sand according to the data transmitted back by the first sensor in real time, and at the same time drives the first driving rod 52 in the pressing mechanism 50 to adjust the angle of the disc 51 in the pressing mechanism 50 to ensure that the depth of the material pressed into the sand is 10 - 15 cm. After the material is pressed into the sand, the device continues to move forward. After the soil covering plate 62 in the compaction mechanism 60 touches the gully pressed out by the pressing mechanism 50, the two soil covering plates 62 are driven by the second driving rod 61 in the compaction mechanism 60 to open and close according to a certain rule to achieve the effect of compacting the sand. Thus, a working cycle is completed.

[0045] The present invention also has the following advantages:

[0046] (1) The operation is relatively simple and does not require the user to carry out a long disassembly and assembly process, avoiding many inconveniences generated by the user during actual use. Therefore, it has strong operability and is not prone to safety accidents during long-term use by the user.

[0047] (2) The assembly relationship involved in this device is clearly hierarchical, easy to assemble, and convenient for replacing vulnerable components in the later stage. This device has a high degree of intelligence and a high degree of application of digital and artificial intelligence technologies. Compared with existing related devices, this device has a moderate size, good mobility, high flexibility, and is suitable for long-term operation in desert areas with complex terrains.

[0048] (3) In the design of the material grabbing mechanism 30, this device adopts a material grabbing structure different from that of existing equipment. It is driven by the transmission mechanism 31 to rotate counterclockwise, and at the same time, it cooperates with the fixedly installed fixed disk 331 to realize the opening and closing of the material grabbing mechanism 30. When the material grabbing mechanism 30 rotates to the designated position, the material grabbing mechanism 30 opens, and the wheat straw falls onto the horizontal conveyor belt in the material spreading mechanism 40 under the action of gravity. The horizontal conveyor belt drives the wheat straw to be conveyed forward to the entrance of the inclined conveyor belt, and then the conveyor belt in the opposite group turns to send the wheat straw into the conveying track in front of and below the material spreading mechanism 40 and keeps the wheat straw always neatly arranged. Finally, the wheat straw falls onto the sand surface from the discharge port of the material spreading mechanism.

[0049] (4) When designing the compaction mechanism 60 of this device, in order to ensure that the depth of the wheat straw pressed into the sand surface can always be maintained at 10 - 15 cm, a single-chip microcomputer system and sensors are adopted. The optimal depth of the wheat straw pressed into the sand surface is calculated based on the data transmitted in real time by the sensors carried by the device, and the first driving rod 52 in the driving pressing mechanism 50 is adjusted in real time according to these data, and the angle of the disk 51 in the pressing mechanism 50 is adjusted to ensure that the depth of the wheat straw pressed into the sand is 10 - 15 cm, which conforms to the research results on what depth of wheat straw pressing can achieve the best sand fixation effect currently.

[0050] (5) The sensors in the compaction mechanism 60 adjust the covering angle and angle of the covering plate 62 according to the real-time data, greatly improving the intelligent level of the device for laying straw checkerboards, thereby effectively improving the sand fixation quality, extending the sand fixation life, and solving the problem of uneven and inconsistent manual laying of straw checkerboards that has troubled in the past.

[0051] The above is only the preferred implementation mode of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention.
