Detailed implementation manners

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0024] Please refer to Figures 1-4, a lawn paving machine of the present invention includes a vehicle body 1, a horizontal flattening assembly, and a vertical flattening assembly; a unwinding assembly for placing bundled lawns is installed on the vehicle body 1; the horizontal flattening assembly includes a belt conveyor assembly for horizontally conveying the lawn; the vertical flattening assembly includes a lifting frame 2 slidably installed on the vehicle body 1 up and down and a flattening assembly installed at the bottom of the lifting frame 2; a first driving assembly 3 for driving the lifting frame 2 to move up and down is installed on the vehicle body 1; the flattening assembly is used for automatically flattening the lawn from the center to both edges; further, the unwinding assembly can adopt a placing rack, a carrying shaft is rotatably installed on the placing rack, and the lawn is wound around the carrying shaft to form a bundle; the unwinding assembly can also adopt other equivalent assemblies with the function of feeding bundled lawns; the belt conveyor assembly can adopt an existing belt conveyor or a chain plate conveyor and other planar conveying assemblies with equivalent effects, and the belt conveyor assembly can be equipped with a driver; the first driving assembly 3 preferably adopts a threaded lead screw, the threaded lead screw is arranged on the vehicle body 1, and the threaded lead screw is in threaded transmission connection with the lifting frame 2; a driving cylinder or other driving devices with equivalent linear lifting driving effects can also be adopted; further, four groups of guide columns are installed on the lifting frame 2, and the guide columns are slidably installed on the vehicle body 1 up and down; during the lawn paving process, the lifting frame 2 moves downward, the flattening assembly presses the lawn on the belt conveyor assembly, and the belt conveyor assembly drives the lawn to move, so that the lawn at the unwinding assembly follows the movement of the vehicle body 1 to gradually release the lawn; the horizontal flattening of the lawn is realized by the horizontal stretching of the belt conveyor assembly on the lawn.

[0025] Specifically, the flattening assembly includes two longitudinal flatteners symmetrically arranged at the bottom of the lifting frame 2. The longitudinal flattener includes a mounting seat 4, a spiral conveyor shaft 5 rotatably installed on the mounting seat 4, and a driving motor 6 for driving the spiral conveyor shaft 5 to rotate; the driving motor 6 can adopt a hydraulic motor, a servo motor and other drivers with rotational driving effects; by starting the driving motor 6, the spiral conveyor shaft 5 rotates, and the linear velocity of the spiral conveyor shaft 5 is equal to the conveying velocity of the belt conveyor assembly for the lawn. While the spiral conveyor shaft 5 presses the lawn downward, it forms a force on the lawn from the middle of the lawn to the edge of the lawn, thereby achieving a vertical flattening effect on the passing lawn; while the spiral conveyor shaft 5 vertically flattens the lawn, it will not form a resistance to the lateral feeding of the lawn, ensuring the normal progress of the lawn and improving the flatness of the lawn, avoiding wrinkles on the lawn, so that the lawn is laid on the ground more smoothly.

[0026] Specifically, the unwinding assembly includes two placing rollers 7 that are arranged in parallel and rotatably installed on the vehicle body 1; the belt conveyor assembly includes a rotating roller 8 rotatably installed on the vehicle body 1 and a conveyor belt 9 sleeved on the rotating roller 8. A rotating shaft 10 is provided at the bottom of the vehicle body 1, and the conveyor belt 9 is sleeved on the rotating shaft 10. Two rollers 11 are installed at both ends of the rotating shaft 10; during the movement of the vehicle body 1, the rollers 11 rotate, the rollers 11 drive the rotating shaft 10 to rotate, and the rotating shaft 10 drives the conveyor belt 9 to move synchronously; the bundled lawns placed on the two placing rollers 7 are unwound synchronously with the traveling speed of the vehicle body 1 driven by the conveyor belt 9, so that the feeding speed of the lawn matches the traveling speed of the vehicle body 1, avoiding excessive feeding or untimely feeding of the lawn, preventing wrinkles or excessive relaxation during the lawn paving process, and further ensuring the paving flatness of the lawn.

[0027] Specifically, the mounting seat 4 is slidably installed on the lifting frame 2, and a second driving assembly for providing power for the synchronous and opposite movement of the mounting seats 4 on the two longitudinal flatteners is installed on the lifting frame 2; the second driving assembly includes a gear 12 rotatably installed on the lifting frame 2 and two racks 13 slidably installed on the lifting frame 2. The gear 12 and the racks 13 are meshed, and the two racks 13 are respectively fixedly connected to the two mounting seats 4; a third driving assembly 14 for driving the gear 12 to rotate is installed on the lifting frame 2; further, a chute is provided on the lifting frame 2, and a pulley is rotatably installed on the mounting seat 4. The pulley is rotatably installed in the chute to realize the sliding connection between the mounting seat 4 and the lifting frame 2; the third driving assembly 14 is preferably a driving shaft, and the output end of the driving shaft is fixedly connected to the gear 12. A stopper for limiting the driving shaft is installed on the lifting frame 2, and the stopper can be a threaded jack or other limiting members with equivalent limiting effects; the third driving assembly 14 can also be a driving member such as a brake stepper motor with equivalent rotation and braking effects; when the width of the lawn changes, the third driving assembly 14 can be rotated to drive the gear 12 to rotate by the third driving assembly 14, and the gear 12 drives the two racks 13 to move synchronously and oppositely, so that the distance between the two mounting seats 4 changes, and the distance between the two flatteners matches the width of the lawn, so as to meet the paving requirements of lawns with multiple widths and improve the applicability of the device.

[0028] Specifically, a pressing assembly is installed on the vehicle body 1, and the pressing assembly includes two rotating plates 15 hingedly installed on the vehicle body 1, a connecting rod 16 fixedly installed between the two rotating plates 15, two mounting frames 17 fixedly installed on the connecting rod 16, a first pressing roller 18 rotatably installed between the two mounting frames 17, and an adjustment assembly that provides power for the rotation of the rotating plate 15; the adjustment assembly includes a tension spring 19, a transmission rod 20 and a driving rod 21, one end of the tension spring 19 is hinged to the connecting rod 16, the other end of the tension spring 19 is hinged to the vehicle body 1, the middle part of the driving rod 21 is hinged to the vehicle body 1, and the driving rod 21 is connected to the rotating plate 15 through the transmission rod 20; further, the driving rod 21 is in a vertical state, the driving rod 21 is hinged to the vehicle body 1 through a hinge shaft, and the two ends of the transmission rod 20 are hinged to the driving rod 21 and the transmission rod 20 respectively; the height position adjustment of the first pressing roller 18 is achieved by toggling the driving rod 21; in a natural state, under the action of the tension spring 19, the first pressing roller 18 is adjusted to the height position of the first pressing roller 18. A pressing roller 18 presses the lawn tightly against the conveyor belt 9. Under the pressing action of the first pressing roller 18, the flatness of the lawn can be further improved, and the friction between the conveyor belt 9 and the lawn can be increased to avoid relative sliding between the lawn and the conveyor belt 9, thereby ensuring the normal transportation of the lawn by the conveyor belt 9 and further improving the lateral flatness of the lawn during paving. In the initial feeding state of the lawn, the driving rod 21 can be pulled, and after being transmitted by the transmission rod 20, the rotating plate 15 drives the connecting rod 16 to move, thereby adjusting the height of the first pressing roller 18, so that the lawn can pass more easily from under the first pressing roller 18, thereby improving the convenience of initial feeding of the lawn. Under the action of the tension spring 19, the elastic contact between the first pressing roller 18 and the lawn is achieved to avoid excessive pressing of the lawn by the first pressing roller 18. At the same time, under the action of the tension spring 19, the first pressing roller 18 can be automatically reset after the height adjustment, without manual intervention, thereby improving the convenience of operation.

[0029] Specifically, a second pressing roller 22 is rotatably installed on the lifting frame 2; further, the first pressing roller 18 and the second pressing roller 22 are arranged in parallel, and under the action of the first pressing roller 18 and the second pressing roller 22, the surface contact between the lawn and the conveyor belt 9 is achieved, and the contact area between the lawn and the conveyor belt 9 is further increased, and the friction between the conveyor belt 9 and the lawn is increased, so that the lawn between the first pressing roller 18 and the second pressing roller 22 is in a laterally flattened state. At the same time, under the action of the first pressing roller 18, the friction between the lawn and the lifting frame 2 can be reduced, avoiding the lifting frame 2 from interfering with the normal movement of the lawn, ensuring the flatness of the lawn paving while improving the smoothness of the lawn feeding.

[0030] Specifically, a power assembly 23 for driving one set of rotating shafts 10 to rotate is installed on the vehicle body 1; the power assembly 23 can adopt a gasoline or diesel engine, and the gasoline or diesel engine is drivingly connected to the rotating shaft 10 through necessary transmission components such as a transmission shaft; by driving the rotating shaft 10 to rotate through the power assembly 23, the automatic advancement of the vehicle body 1 is realized; there is no need to manually push the vehicle body 1 to advance, which improves the convenience of use and further reduces the amount of manual operation; further, relevant speed regulation components and brake components for controlling the advancing speed and braking of the vehicle body 1 can be installed on the vehicle body 1. The power assembly 23, speed regulation components and brake components are all conventional existing technologies in the market, and their specific connection structures and principles will not be elaborated here.

[0031] Specifically, a pressing roller 24 is rotatably installed on the vehicle body 1; through the pressing roller 24, the lawn laid on the ground can be rolled, further improving the laying tightness between the lawn and the ground.

[0032] Specifically, a plurality of groups of evenly distributed spiked teeth 25 are arranged on the pressing roller 24; while the pressing roller 24 presses the lawn, the spiked teeth 25 puncture the air bubbles and bulges generated during the lawn laying process, and the gas is discharged outward, so that the root part of the lawn contacts the ground, further improving the adhesion tightness between the lawn and the ground to ensure that the lawn roots are in direct contact with the ground. The holes formed by the spiked teeth 25 on the lawn can improve the air permeability of the lawn. At the same time, when the lawn is irrigated, water can more easily enter the root of the lawn to improve the survival rate of the lawn.

[0033] Specifically, a mudguard 26 is installed on the vehicle body 1 near the pressing roller 24; through the mudguard 26, the mud carried by the spiked teeth 25 in the rolling state of the pressing roller 24 can be blocked to prevent the mud from contacting the human body; at the same time, it avoids the human body from being in close contact with the spiked teeth 25 at the pressing roller 24, reduces the accident rate of mechanical injury to people, and plays a certain protective role.

[0034] During use, place the bundled lawn between the two placing rollers 7. One end of the bundled lawn passes under the longitudinal flattening assembly. Pull the driving rod 21. After being transmitted by the transmission rod 20, the rotating plate 15 drives the connecting rod 16 to move, thereby adjusting the height of the first pressing roller 18 to make it easier for the lawn to pass under the first pressing roller 18. Under the action of the tension spring 19, the first pressing roller 18 resets itself and presses the lawn on the conveyor belt 9. Drive the gear 12 to rotate through the third driving assembly 14. After being transmitted by the gear 12 and the rack 13, the distance between the two flatteners is adapted to the width of the lawn. The first driving assembly 3 drives the lifting frame 2 to move down until the second pressing roller 22 and the spiral conveying shaft 5 are in close contact with the lawn. The power assembly 23 drives the rotating shaft 10 to rotate, the roller 11 rotates, the vehicle body 1 moves forward, and the conveyor belt 9 moves synchronously with the vehicle body 1. While the lawn is being horizontally stretched by the conveyor belt 9, it is being longitudinally stretched in both directions by the spiral conveying shafts 5 on the two flatteners. The flattened lawn bypasses the end of the conveyor belt 9 and extends downward in the traveling direction of the vehicle body 1 and is laid on the ground. While the pressing roller 24 presses the lawn, the thorn teeth 25 perform bubble-breaking treatment on the lawn, realizing the flat laying of the lawn.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
