Description
Technical Field
[0001] This application relates to the field of greening projects, and more specifically, to a rapid grass-laying device for greening projects. Background Technology
[0002] The turf laying device is a piece of equipment specifically designed for landscaping projects. It enables the mechanized laying of lawns. Its core consists of a support frame, a conveying mechanism, and a compaction component. It is compatible with various landscaping materials such as turf rolls and turf mats. Through automated conveying and leveling compaction, it significantly reduces manual labor. It is widely used in parks, green spaces, factory greening, and other scenarios, improving turf laying efficiency and shortening the construction cycle. It is a key piece of equipment for achieving rapid vegetation coverage in modern engineering landscaping.
[0003] Chinese patent application number 202122866667.8 discloses a rapid turf-laying device for landscaping in construction projects, comprising a fixed plate and a turf roller. The lower end face of the fixed plate has a groove, within which two symmetrically arranged sliders are slidably connected. Each slider has a fixed block fixedly connected to its lower end. The fixed plate has a moving mechanism for moving the two fixed blocks. Grooves are formed on the opposite sidewalls of the two fixed blocks, and clamping mechanisms for holding the turf roller are provided within each groove. This invention has a reasonable structure. By setting up clamping and moving mechanisms, the turf roller is clamped, improving its stability. By incorporating a power motor, automatic turf laying is achieved, improving work efficiency.
[0004] The above solution has the following shortcomings: When in use, the turf roller can be rolled up and down by means of a rotating turf roller and a moving mechanism to achieve the effect of rapid laying. However, the width of the turf roller that the above device can adapt to is relatively limited. When turf rollers of different widths are used, the existing device cannot adapt well and therefore needs to be improved. Utility Model Content
[0005] To overcome the above shortcomings, this application provides a rapid turf laying device for engineering landscaping, which aims to improve the problem that the device cannot be adapted to turf rolls of different widths, thus reducing its practicality.
[0006] This application provides a rapid grass-laying device for landscaping, comprising two assembleable mobile devices. One end of each mobile device is provided with an installation sleeve for mounting the two mobile devices. The inner side of each mobile device is equipped with a hydraulic swing arm for adjusting the height of the grass roll. The free end of the hydraulic swing arm is equipped with a roller connector. Rollers are mounted on the surface of the roller connectors of the two mobile devices. The inside of the installation sleeve is equipped with a square steel for splicing the two mobile devices.
[0007] In one specific implementation, a protective box is provided on the top of the mobile device, wherein an angle adjustment motor is installed inside the protective box, and the output end of the angle adjustment motor is fixed to the tail end of the hydraulic swing arm. A push rod is also provided on the top of the protective box to facilitate the user to push the mobile device.
[0008] In the above implementation process, the angle of the hydraulic swing arm can be adjusted by adjusting the angle adjustment motor, which can be adjusted according to the change of straw roll thickness.
[0009] In one specific implementation, the mounting sleeve has a hollow structure, with a through hole at the top. A pin that can be inserted into the through hole is provided above the through hole, and a tension spring that pulls the pin downward is fixed between the upper half of the pin and the top surface of the mounting sleeve.
[0010] In the above implementation process, the square steel can be quickly locked by the pin, which facilitates the subsequent replacement of square steel of different lengths.
[0011] In one specific implementation, bolt holes are provided at both ends and the middle of the top surface of the square steel. The bolt holes at both ends of the top surface of the square steel are aligned with the through holes of the mounting sleeve. At the same time, the pins are inserted into the bolt holes at both ends of the top surface of the square steel to lock the square steel. A traction frame fixed by bolts is installed at the bolt hole in the middle of the top surface of the square steel.
[0012] In the above implementation process, bolt holes are opened on the top surface of the square steel to facilitate the connection between the square steel and the traction frame and the mounting sleeve, so that the two mobile devices can be spliced together.
[0013] In one specific implementation, the bottom end of the traction frame is provided with square sleeve holes on both sides that match the outer wall of the square steel, and the traction frame is sleeved on the surface of the square steel.
[0014] In the above implementation process, the connection stability between the traction frame and the square steel is improved by using a fitting bolt connection.
[0015] In one specific implementation, the hydraulic swing arm consists of two opposing folding arms, and the surfaces of the two folding arms are provided with hydraulic rods for controlling the folding of the hydraulic swing arm, wherein the extension end of the hydraulic rod is provided with an elastic element composed of a telescopic rod and a spring.
[0016] In the above process, by using the folding method in conjunction with the rebound force of the elastic element, a certain downward pressure can be provided when laying turf rolls or turf mats, so that the turf rolls or turf mats are compacted during the laying process, eliminating the need for subsequent compaction operations and improving the efficiency of turf laying.
[0017] In one specific implementation, the end of the hydraulic swing arm away from the angle adjustment motor is provided with a mounting bracket for mounting the coiling rod connector, wherein the mounting bracket is provided with a connection hole.
[0018] In the above implementation process, the mounting bracket can be used to install the roller connector and the roller with turf rolls or grass mats wound on the hydraulic swing arm.
[0019] In one specific implementation, the reel connector has an insertion hole inside that corresponds to the connection hole of the mounting bracket. A threaded rod for fixing the reel connector to the side of the mounting bracket and a matching nut are inserted into the connection hole and the insertion hole. A rotatable bushing is provided on the surface of the reel connector, and a baffle is provided on the inner side of the bushing.
[0020] In the above process, the rotatable bushing can reduce the frictional resistance of turf rolls and turf mats during transportation, allowing the material to be released more smoothly during laying.

[0036] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.
[0037] Please see Figures 1-8This application provides a rapid grass-laying device for engineering landscaping, including two assembleable mobile devices 1. The bottom of each mobile device 1 is equipped with a moving roller 11 for easy movement. One end of each mobile device 1 is welded with an installation sleeve 2 for mounting the two mobile devices 1. The installation sleeve 2 has a hollow structure to accommodate the cross-sectional dimensions of square steel 6. The top of the installation sleeve 2 has a through hole, and a pin 22 that can be inserted into the through hole is provided above the through hole. A tension spring 21 is fixed between the upper half of the pin 22 and the top surface of the installation sleeve 2 to pull the pin 22 downward. The preload of the tension spring 21 ensures that the pin 22 always has downward pressure, which can quickly lock the square steel 6 and facilitate the subsequent replacement of square steel 6 of different lengths according to the construction width.
[0038] Specifically, the inner side of the mobile device 1 is equipped with a hydraulic swing arm 3 for adjusting the height of the turf roll via a bearing seat. The hydraulic swing arm 3 consists of two opposing folding arms. The surfaces of the two folding arms are hinged by pins to a hydraulic rod 31 that controls the folding of the hydraulic swing arm 3. The cylinder of the hydraulic rod 31 is fixed to the frame of the mobile device 1, and the piston rod is connected to the middle of the folding arm. The extension rod end of the hydraulic rod 31 is provided with an elastic element 32 composed of a telescopic rod and a spring. By folding and cooperating with the rebound force of the elastic element 32, downward pressure can be provided when laying turf rolls or turf mats, so that the turf rolls or turf mats are directly compacted and adhered to the ground during the laying process, without the need for subsequent separate compaction operations, effectively improving the efficiency of turf laying.
[0039] The end of the hydraulic swing arm 3 furthest from the angle adjustment motor 14 is welded with a mounting bracket 33 for mounting the coil rod connector 4. The mounting bracket 33 consists of two parallel steel plates, the spacing of which matches the thickness of the coil rod connector 4. The mounting bracket 33 has symmetrically arranged connection holes, which allow the coil rod connector 4 and the coil rod 5 wound with turf rolls or grass mats to be stably mounted on the hydraulic swing arm 3. The free end of the hydraulic swing arm 3 is equipped with the coil rod connector 4, which has an insertion hole 41 corresponding to the connection hole of the mounting bracket 33. The inner wall of the insertion hole 41 is tapped with internal threads. The connection hole and the insertion hole 41 are fitted with threaded rods and matching nuts for fixing the coil rod connector 4 to the side of the mounting bracket 33. Double nuts are used to lock and prevent loosening.
[0040] The surface of the roller connector 4 is connected to a rotatable bushing 42 via a bearing. The bushing 42 is made of wear-resistant cast iron, with its inner wall interference-fitted with the outer ring of the bearing and its outer side precision ground. A baffle with a diameter larger than the roller 5 is welded to the inner side of the bushing 42. The rotatable bushing 42 converts the sliding friction during the release of the turf roll into rolling friction, reducing frictional resistance and allowing the material to be released more smoothly during laying. The surface of the bushing 42 is vulcanized with a layer of anti-slip rubber, which increases the static friction with the roller 5, improves the connection stability between the bushing 42 and the roller 5, and reduces the relative wear between the bushing 42 and the roller 5 when unwinding the turf roll. Two of the moving devices 1 have a rod 5 mounted on the surface of the rod connector 4. The rod 5 is hollow and is sleeved on the surface of the bushing 42. The inner wall of the rod 5 is in clearance fit with the outer wall of the bushing 42. At the same time, the end face of the rod 5 abuts against the surface of the baffle. The baffle restricts the axial displacement of the rod 5. The detachable rod 5 allows for quick replacement according to the specifications of the straw roll.
[0041] The mounting sleeve 2 houses a square steel 6 for splicing two mobile devices 1. Its cross-sectional dimensions are adapted to the hollow structure of the mounting sleeve 2, and its length can be customized according to the construction width. Bolting holes are provided at both ends and the center of the top surface of the square steel 6. The spacing between these holes corresponds to the through holes in the mounting sleeve 2. The bolting holes at both ends of the top surface of the square steel 6 are aligned with the through holes in the mounting sleeve 2. Simultaneously, pins 22 are inserted into the bolting holes at both ends of the top surface of the square steel 6 to lock it in place, ensuring a fixed spacing between the two mobile devices 1 after splicing. A traction frame 7, secured with bolts, is installed at the bolting hole in the center of the top surface of the square steel 6. The bolting holes on the top surface of the square steel 6 facilitate precise docking between the square steel 6, the traction frame 7, and the mounting sleeve 2, ensuring a stable splicing of the two mobile devices 1. The bottom of the traction frame 7 has square sleeve holes on both sides that match the outer wall of the square steel 6. The inner wall of the sleeve hole is fitted with the outer wall of the square steel 6 with a clearance. After the traction frame 7 is fitted onto the surface of the square steel 6, it is locked with bolts. By using the fitting bolt connection method, the connection stability between the traction frame 7 and the square steel 6 is greatly improved, and loosening during traction is avoided.
[0042] The top of the mobile device 1 is welded with a protective box 12, which is rainproof and dustproof. Inside the protective box 12, an angle adjustment motor 14 is mounted via a shock-absorbing bracket. The motor output shaft is fixed to the tail end of the hydraulic swing arm 3 via a coupling to ensure stable power transmission. The top of the protective box 12 is also welded with a push rod 13 for easy pushing of the mobile device 1 by the user. The angle adjustment motor 14 rotates the hydraulic swing arm 3 by turning it forward and backward, which can adjust the angle of the hydraulic swing arm 3. This allows for real-time adjustment of the laying height according to changes in the thickness of the straw roll, ensuring a uniform laying effect.
[0043] The working principle of the rapid turf laying device for landscaping in this project is as follows: When using the device, the traction frame 7 is first fixed in the middle of the square steel 6 to complete the splicing. The square steel 6 is inserted into the mounting sleeves 2 of the two moving devices 1 and locked by the pin 22 and the tension spring 21. The turf roll 5 is put on the bushing 42 of the turf roll connector 4 and the turf roll connector 4 is fixed to the mounting frame 33 of the hydraulic swing arm 3 by the threaded rod. The push rod 13 is pushed or the device is moved by the traction frame 7. The angle adjustment motor 14 adjusts the angle of the hydraulic swing arm 3 to match the thickness of the turf roll. The hydraulic rod 31 drives the folding arm to move. With the rebound force of the elastic element 32, the turf roll contacts the ground and applies downward pressure. During the movement, the bushing 42 rotates with the release of the turf roll, reducing frictional resistance. The turf roll is directly compacted during laying, realizing continuous and efficient turf laying operation.
[0044] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
