Device for leveling and spreading quartz sand among grass filaments of artificial turf

Abstract

The invention discloses a device for leveling and spreading quartz sand among grass filaments of an artificial turf, and belongs to the technical field of playground construction devices. A differential moving assembly is arranged on the spreading box body, a flattening roller is arranged at the bottom end of the spreading box body, the differential moving assembly is connected with the differential spreading assembly through a chain, two moving motors are arranged in the spreading box body, an anti-blocking rocker penetrates through the inner wall of the spreading box body and is rotationally connected with the spreading box body, and a storage battery is arranged in the spreading box body. A remote control assembly is arranged on the storage battery and connected with a moving motor and a switching motor through wires, a tensioning gear rod is arranged on the side, away from the moving motor, of the moving differential assembly, the moving motor is connected with the two ends of the tensioning gear rod through a chain, and the tensioning gear rod is connected with the output end of the switching motor through a telescopic connecting rod. A spreading brush is arranged on one side of the spreading box body, a pushing handle is arranged at the upper end of the spreading box body, and a plurality of universal wheels are arranged at the bottom end of the spreading box body. The device has the effect of automatically laying the artificial lawn quartz sand.

Description

technical field [0001] The invention relates to the technical field of sports field construction devices, in particular to a device for evenly spreading quartz sand between grass filaments of an artificial lawn. Background technique [0002] As one of the important components of the sports field, artificial turf is very important in terms of splicing and laying, while the traditional production process is manual intervention or construction, which wastes time and a lot of manpower, while functional lawns such as football fields are often constructed Quartz sand and black rubber particles will be directly and evenly sprinkled between the grass filaments. These substances not only increase the friction of the lawn, but also protect the roots of the grass filaments from damage, making the artificial turf more durable and convenient for construction. Attention must be paid to the flatness. The qualified construction standard is that the flatness should reach more than 95%, and t...

[0002] As one of the important components of the sports field, artificial turf is very important in terms of splicing and laying, while the traditional production process is manual intervention or construction, which wastes time and a lot of manpower, while functional lawns such as football fields are often constructed Quartz sand and black rubber particles will be directly and evenly sprinkled between the grass filaments. These substances not only increase the friction of the lawn, but also protect the roots of the grass filaments from damage, making the artificial turf more durable and convenient for construction. Attention must be paid to the flatness. The qualified construction standard is that the flatness should reach more than 95%, and the error should be kept within 3 millimeters. Traditional manual spreading cannot meet this practical requirement, and artificial turf is in some places. There are often potholes in the lot, which will easily cause the accumulation of quartz sand and rubber particles, and the effect of artificial turf leveling cannot be achieved.

[0003] Common spreading devices on the market have various shortcomings in use, and they cannot meet the corresponding technical requirements. For example, the Chinese utility model patent specification: CN201920485882.3 discloses an artificial lawn laying aid for landscaping construction. device, the sand storage hopper used is a trapezoidal structure, the inside of the sand storage hopper has a cavity, and the frame is welded and fixed on the outside of the bottom of the sand storage hopper; In the process of pushing the body forward, the brush can push forward the impurities encountered during the turf laying, clean them up, and increase the smoothness of the turf laying. The installed combing brush can use the driving motor to drive the combing brush to rotate when pushing the body to spread quartz sand, so that the quartz sand spread on the turf can be evenly spread on the turf. It is easy to use, simple to operate, and saves laying steps , but the spreading accuracy of the device is too low, and it is still unable to solve the problem of artificial turf in potholes
