Furthermore, this utility model also relates to a lawn laying device including the aforementioned construction auxiliary device. Background Technology

[0002] Sunken green spaces are green areas lower than the surrounding ground level, utilizing open space to collect and store rainwater, thus reducing runoff. The construction of permeable concrete mainly includes processes such as paving, shaping, surface treatment, and joint treatment, which can be carried out mechanically or manually. Surface treatment primarily aims to improve the appearance of the formed permeable concrete surface through finishing or cleaning. The integrated construction support system for both aims to improve the efficiency and quality of permeable concrete paving and sunken green space construction, promoting the sustainable development of urban green space systems.

[0003] Before being laid, the turf is rolled up. Existing construction aids use a conveying mechanism to transport the turf to the ground and compact it with rollers at the bottom. For example, the construction aid disclosed in the technical solution of patent number 202323341282.5 uses a similar method. However, due to factors such as the actual speed of movement, the contact time between the rollers and the turf, and the different pressing force of the rollers at different thicknesses, the actual compaction effect is not good, and the laying thickness is uneven, still requiring manual leveling. Utility Model Content

[0029] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in many different ways as defined and covered below.

[0031] like Figures 1 to 3 As shown, the construction auxiliary device in this embodiment is applied to the integrated construction of permeable concrete and sunken green space, and includes:

[0032] The frame 100 serves as a structural support, and a walking mechanism is provided at the bottom of the frame 100.

[0033] The flat slab 403 is connected to the bottom of the frame 100 and is used to press the concrete road surface or green surface to flatten the concrete road surface or green surface.

[0034] An adjustment component is connected to the flat panel 403 and the frame 100 respectively and is used to adjust the distance between the flat panel 403 and the frame 100;

[0035] The first pressure roller 300 is connected to the bottom of the frame 100 and is used to press the concrete road surface or green surface to flatten the concrete road surface or green surface.

[0036] The first connecting component 200 is connected to the first pressure roller 300 and the frame 100 respectively, and is used to adjust the distance between the first pressure roller 300 and the frame 100.

[0037] The walking mechanism of the frame 100 can be a walking wheel, and the frame 100 is equipped with a handrail or other structure so that the frame 100 can be used as a trolley.

[0038] During use, a conveying mechanism is installed on the frame 100 to transport and spread the turf to the bottom of the frame 100. The conveying mechanism is implemented with reference to existing technology.

[0039] In this embodiment, the end of the flat paving board 403 facing the forward direction of the frame 100 has an upward-curving part, which changes the angle of contact with the turf, making the contact transition smoother and avoiding interference that could cause the turf to curl or have uneven thickness.

[0040] Understandably, the frame 100 of this construction auxiliary device is used in the form of a trolley. During the pushing process, the conveying mechanism set on the frame 100 transports the turf, which is then pressed onto the turf by the first pressure roller 300, thus compacting the green turf onto the permeable concrete pavement. The flat paving plate 403 compacts the green turf over a large area. As the frame 100 moves, the green turf is compacted and flattened, effectively ensuring the flatness of the greening. The height of the first pressure roller 300 is adjusted by the first connecting component 200 to match the laying of turf of different thicknesses, and the height of the flat paving plate 403 is adjusted by the adjusting component to match the laying of turf of different thicknesses. This device is simple to operate, can adapt to the laying of turf of different thicknesses, effectively compacts and flattens the permeable concrete pavement and green turf, and improves the efficiency of green turf laying.

[0041] Furthermore, the device also includes a second pressure roller 503 and a second connecting assembly connected to the second pressure roller 503 and the frame 100 respectively. The second connecting assembly is used to adjust the distance between the second pressure roller 503 and the frame 100. The flat paving plate 403 is positioned at the middle of the lower part of the frame 100, the first pressure roller 300 is positioned below the first end of the frame 100, and the second pressure roller 503 is positioned below the second end of the frame 100. The first connecting assembly 200 and the second connecting assembly can use different adjustment methods to adjust the height position of the pressure rollers. For example, the first connecting assembly 200 is an elastic adjustment structure, which maintains a pressing position on the turf that matches the thickness of the turf under elastic action, while the second connecting assembly is a mechanical adjustment structure that can be fixed in the adjustment position to match the turf thickness and ensure the compaction effect.

[0042] Specifically, the second connecting component includes a drive mechanism 501 disposed on the frame 100 and a connecting rod 502 disposed on the drive end of the drive mechanism 501 and connected to the second pressure roller 503. The drive mechanism 501 can be a rotating mechanism such as a motor. The action of the drive mechanism 501 causes the connecting rod 502 to swing, thereby adjusting the distance between the second pressure roller 503 and the frame 100, thereby achieving matching of the thickness of the green turf and ensuring the compaction effect. The connecting rod 502 includes a first connecting section connected to the drive mechanism 501 and a second connecting section connected to the second pressure roller 503. The first connecting section and the second connecting section are set at a preset angle. By designing the connecting rod 502 with a two-end structure with a certain angle, horizontal movement can be reduced when adjusting the height position of the second pressure roller 503. At the same time, when the torque output by the drive mechanism 501 acts on the second pressure roller 503 during the compaction process, the torque can be kept consistent in different thicknesses, effectively ensuring the compaction and flattening effect and avoiding secondary manual adjustment.

[0043] In some embodiments, the adjustment assembly includes a first connecting rod 402 with both ends hinged to the flat panel 403 and the frame 100, respectively, and at least one second connecting rod 401 arranged parallel to the first connecting rod 402, with both ends of the second connecting rod 401 hinged to the flat panel 403 and the frame 100, respectively. The adjustment assembly also includes a telescopic mechanism 404 with both ends hinged to the first connecting rod 402 and the frame 100, respectively. The telescopic mechanism 404 is an electrically operated telescopic rod, used to extend or retract to drive the first connecting rod 402. The relative swing of the frame 100 causes the flat turf 403 to rise and fall. The second link 401 is the same length as the first link 402. Under the constraint of the second link 401, the flat turf 403 remains parallel to the bottom surface of the frame 100, thereby ensuring that the distance can be adjusted to accommodate different thicknesses of turf and ensuring the compaction and flattening effect. The first link 402 and the second link 401 are spaced apart along the longitudinal direction of the frame 100. Multiple second links 401 and multiple first links 402 can be set and arranged at intervals along the transverse direction of the frame 100.

[0044] In some embodiments, the first connecting assembly 200 includes elastic rods 202 arranged laterally at intervals along the bottom of the frame 100 and fixing blocks 203 symmetrically distributed and connected to the ends of the two elastic rods 202 respectively. It also includes a connecting plate 201 disposed at the bottom of the frame 100. The elastic rods 202 are mounted on the frame 100, each elastic rod 202 including a rod body and a spring sleeved on the rod body. The two ends of the spring respectively abut against the connecting plate 201 and the fixing blocks 203. The rod body is... The telescopic rod and the fixing block 203 have shaft holes for cooperating with the first pressure roller 300. The two ends of the first pressure roller 300 are inserted into the shaft holes. Under the action of the elastic rod 202, the first pressure roller 300 keeps pressed against the turf at all height positions. It should be noted that the pressure of the first pressure roller 300 on the turf is different at different height positions due to the influence of the spring compression. This device initially compacts the turf with the first pressure roller 300, and the flat plate 403 and the second pressure roller 503 ensure the compaction and flattening effect, and are adapted to different turf thicknesses.

[0045] In some embodiments, a connecting cylinder 303 is provided at the end of the roller body 301 of the first pressure roller 300, and an elastic buckle 204 is provided on the fixing block 203 for extending relative to the fixing block 203 under elastic force. The connecting cylinder 303 has a mating hole 304 radially provided for engaging with the elastic buckle 204. A sleeve 302 is provided at the end of the first pressure roller 300, and the connecting cylinder 303 passes through the sleeve 302. The connecting cylinder 303 and the sleeve 302 are respectively provided with axial limiting structures. An elastic element is provided inside the sleeve 302 to connect the connecting cylinder 303 and the end of the first pressure roller 300 respectively. After the shaft hole of the fixing block 203 is inserted, the elastic buckle 204 extends out into the insertion mating hole 304 under the action of elastic force to limit the axial movement of the first pressure roller 300. The fixing block 203 has a drive handle on one side that is driven to connect with the elastic buckle 204. The drive handle is used to drive the elastic buckle 204 to retract into the fixing block 203 to disengage from the mating hole 304. During disassembly, the drive handle drives the elastic buckle 204 to retract into the fixing block 203 to disengage from the mating hole 304, and pushes the connecting cylinder 303 into the sleeve 302 to disengage the connecting cylinder 303 from the shaft hole, thereby removing the first pressure roller 300. The operation is simple and easy to maintain.

[0046] On the other hand, this embodiment also provides a lawn laying device, which uses the above-mentioned construction auxiliary device, and a conveying mechanism is provided on the frame to accommodate and convey the lawn to the bottom of the frame.

Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
