Description

Technical Field

[0001] This utility model relates to the field of artificial turf, specifically to an environmentally friendly infill granule. Background Technology

[0002] Artificial turf is widely used in various sports fields, including football, rugby, baseball, and softball fields. Sports-grade artificial turf has now evolved to its third generation. In this system, after installation, the artificial turf is filled with quartz sand and elastic granules to provide excellent surface performance. The elastic granules are primarily derived from crushed waste rubber or granules made from TPE rubber. However, people have become increasingly aware of the environmental risks associated with these elastic granules. During use, these granules are prone to splashing and runoff, entering the soil and sewers, polluting water and soil, and they do not degrade.

[0003] Therefore, people have developed some biomass resilient pellets, such as sawdust pellets, wood-plastic pellets, cork pellets, crushed coconut shell pellets, and nutshell pellets. Although these resilient pellets can biodegrade after being washed away, they have poor elasticity and are more easily washed away by rainwater, affecting the use of the site. Therefore, there is a need to develop an environmentally friendly infill pellet that is elastic, not easily washed away, and biodegradable. Utility Model Content

[0004] In view of the problems existing in the prior art, this utility model proposes an environmentally friendly filler particle that is elastic, not easy to lose, and degradable, making it environmentally friendly.

[0005] The technical solution of this utility model to solve the above technical problems is as follows: an environmentally friendly filler particle is provided, including a particle body, the particle body is composed of a core and a shell, the shell is wrapped around the core, and a number of protrusions are provided on the outside of the shell, and a gap is left between two adjacent protrusions.

[0006] The further defined technical solution of this utility model is as follows:

[0007] Preferably, the core is dense quartz sand or other mineral particles with a particle size of 0.5-2 mm and a round or elliptical shape.

[0008] Preferably, the outer shell is made of biodegradable plastic.

[0009] Preferably, the protrusion is a mushroom-shaped protrusion with a height of 0.1-2mm.

[0010] Preferably, the upper end of the mushroom-shaped protrusion is disc-shaped.

[0011] The beneficial effects of this utility model are as follows: This utility model has a simple structure. The core of the particles is made of high-density quartz sand or other mineral particles, which increases the weight of the filling particles and makes them less likely to be lost with rainwater. At the same time, the outer shell of the particles is distributed with mushroom-shaped protrusions, which can give the particles a certain degree of elasticity. In addition, the mushroom-shaped protrusions also help to increase the friction and connection between the particles, reducing the number of particles splashing during movement.

[0014] This embodiment provides an environmentally friendly filler particle with the following structure: Figure 1-2 As shown: It includes a particle body, which consists of a core 2 and a shell 1. The shell 1 wraps around the core 2. The core is high-density quartz sand or other mineral particles with a particle size of 2mm and a round or elliptical shape. The shell is made of biodegradable plastic. Several mushroom-shaped protrusions 3 with a height of 1mm are provided on the outside of the shell. The upper end of the mushroom-shaped protrusions is disc-shaped, and there is a gap between two adjacent mushroom-shaped protrusions.

[0015] The structure of this embodiment is simple. The core of the particles is made of high-density quartz sand or other mineral particles, which increases the weight of the filling particles and makes them less likely to be lost with rainwater. At the same time, the outer shell of the particles is distributed with mushroom-shaped protrusions, which can give the particles a certain degree of elasticity. In addition, the mushroom-shaped protrusions also help to increase the friction and interlocking between the particles, reducing the number of particles splashing during movement.

[0016] In addition to the above embodiments, this utility model may have other implementation methods. All technical solutions formed by equivalent substitution or equivalent transformation fall within the protection scope claimed by this utility model.
