Description

Technical Field

[0001] The utility model relates to the technical field of lawns, and specifically relates to a filling-free artificial lawn. Background Art

[0002] Artificial lawns are divided into injection-molded artificial lawns and woven artificial lawns according to the production process. The injection-molded artificial lawns adopt the injection molding process, extrude plastic particles in a mold at one time, and use the bending technology to bend the lawn so that the grass blades are arranged regularly at equal distances and in equal amounts, and the height of the grass blades is completely uniform. As a new type in sports lawns, the filling-free artificial lawns do not require the complicated process of filling quartz sand and rubber particles, making sports healthier, safer, and more environmentally friendly.

[0003] The existing patent with the authorized announcement number of "CN207062691U" discloses a filling-free artificial grass, which includes a base cloth and a plurality of clusters of artificial grass filaments woven on the base cloth. Each cluster of artificial grass filaments includes straight filaments and curved filaments, and the curved filaments surround the straight filaments to support the straight filaments; the cross-section of the curved filaments is a rhombus to enhance the elastic strength of the curved filaments; the straight filaments are convexly provided with reinforcing ribs extending in the up-and-down direction to improve the strength of the straight filaments; the reinforcing ribs are arranged in the middle of the straight filaments; the cross-section of the reinforcing ribs is a semi-elliptical shape. For this filling-free artificial lawn, the straight filaments have greater strength, and the straight filaments and the curved filaments cooperate with each other to improve the buffering effect and the resilience effect of the artificial lawn.

[0004] However, the following deficiencies exist in this device:

[0005] 1. The grass filaments of the above device are arranged above the base cloth. When pedestrians pass through the lawn, they will directly step on the roots of the grass filaments, which easily causes the grass filaments to break and damage, reducing the service life of the grass filaments. Moreover, the fixing effect of the roots of the grass filaments is poor, and the grass filaments are prone to falling off.

[0006] 2. When the artificial lawn is in use, its drainage performance is very important. However, the drainage performance of the above device is poor, and water is likely to accumulate on the top of the lawn on rainy days, resulting in pedestrians slipping easily when passing through the lawn. Summary of the Utility Model

[0007] The purpose of the utility model is to provide a filling-free artificial lawn to solve the problems presented in the above background art.

[0008] To achieve the above purpose, the utility model provides the following technical solution: A filling-free artificial lawn, including a base cloth, a buffer layer is arranged at the bottom of the base cloth, a wear-resistant layer is arranged at the bottom of the buffer layer, a plurality of groups of limiting grooves are opened inside the wear-resistant layer, a plurality of anti-detachment balls are sleeved inside the plurality of groups of limiting grooves, artificial grass filaments are arranged at the top of the anti-detachment balls, a plurality of groups of drainage grooves are opened at the bottom of the wear-resistant layer, and a plurality of groups of drainage holes communicated with the drainage grooves are evenly opened at the top of the base cloth.

[0009] Preferably, a diversion groove is formed at the top of the drain hole, and the shape of the diversion groove is funnel-shaped, which can divert the water flow on the top of the lawn into the drain hole.

[0010] Preferably, a plurality of through holes communicating with the limiting grooves are formed at the top of the bottom cloth, and the artificial grass filaments pass through the inner sides of the through holes, which can limit the artificial grass filaments.

[0011] Preferably, the buffer layer is made of rubber, which can buffer the pressure received by the lawn.

[0012] Preferably, the wear-resistant layer is made of asphalt, which can improve the wear resistance of the device.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows: the unfilled artificial turf;

[0014] 1. Through the mutual cooperation among the wear-resistant layer, the artificial grass filaments, the anti-disengagement balls and the limiting grooves, the device can prevent the roots of the artificial grass filaments from being damaged by pedestrians directly stepping on them by installing the artificial grass filaments on the anti-disengagement balls. At the same time, through the limiting effect on the anti-disengagement balls, the artificial grass filaments can be prevented from falling off easily, improving the service life of the artificial grass filaments and thus extending the overall life of the lawn;

[0015] 2. Through the mutual cooperation between the drain holes and the drain grooves, when the device is used in rainy days, the rainwater on the top of the lawn can be diverted into the drain grooves through a plurality of drain holes and discharged outwards, thereby preventing water accumulation on the top of the lawn, making the lawn more stable to walk on and not prone to slipping.

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1 - 3 , an embodiment provided by the present utility model: a filling-free artificial turf, including a base cloth 1, a buffer layer 2 is arranged at the bottom of the base cloth 1, the material of the buffer layer 2 is rubber, which can buffer the pressure received by the turf, a wear-resistant layer 3 is arranged at the bottom of the buffer layer 2, the material of the wear-resistant layer 3 is asphalt, which can improve the wear resistance of the device, a plurality of limiting grooves 8 are formed inside the wear-resistant layer 3, an anti-off ball 5 is sleeved inside the plurality of limiting grooves 8, and artificial grass filaments 4 are arranged at the top of the anti-off ball 5;

[0022] A plurality of through holes communicating with the limiting grooves 8 are formed at the top of the base cloth 1, and the artificial grass filaments 4 pass through the inside of the through holes, which can limit the artificial grass filaments 4. A plurality of drainage grooves 7 are formed at the bottom of the wear-resistant layer 3, and a plurality of drainage holes 6 communicating with the drainage grooves 7 are uniformly formed at the top of the base cloth 1. A diversion groove is formed at the top of the drainage hole 6, and the shape of the diversion groove is funnel-shaped, which can divert the water flow on the top of the turf into the drainage hole 6.

[0023] Working principle: When the device is in use, when pedestrians pass through the turf, the buffer layer 2 can buffer the pressure received by the turf, and the wear-resistant layer 3 can improve the wear resistance of the device. Since the roots of the artificial grass filaments 4 are on the anti-off ball 5, pedestrians passing through the turf will not directly step on the grass roots. At the same time, by limiting the anti-off ball 5, the artificial grass filaments 4 can be prevented from falling off, and the service life of the artificial grass filaments 4 is improved;

[0024] When the device encounters rainy days, the rainwater can flow into the drainage grooves 7 from the drainage holes 6 through the diversion of the diversion grooves, and then be discharged out through the drainage grooves 7, which can prevent water accumulation on the top of the turf.
