연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

Disclosed is a synthetic athletic field grooming apparatus configured to be pulled by a vehicle to maintain the synthetic athletic field. The apparatus comprises a frame having a coupling mechanism for mounting the apparatus to the vehicle. At least one broom channel is coupled to the frame rearward of the coupling mechanism, and forward and aft rows of brushes are attached to the broom channel. The aft row of brushes is spaced apart from and rearward of the forward row of brushes to allow infill of the synthetic athletic field to flick upward from the forward row while containing the infill for re-agitation from the aft row. The coupling mechanism and the frame allow an attached vehicle to control a downward pressure forcing the rows of brushes into contact with the synthetic athletic field with a desired force. Also disclosed is a method of grooming a synthetic athletic field.

1. A synthetic athletic field grooming apparatus configured to be pulled by a vehicle across a synthetic athletic field for use in maintaining the synthetic athletic field, the synthetic athletic field grooming apparatus comprising: a frame having a coupling mechanism at a front of the grooming apparatus for mounting the grooming apparatus to the vehicle;at least one broom channel coupled to the frame rearward of the coupling mechanism and extending longitudinally from a first side of the at least one broom channel to a second side of the at least one broom channel;a forward row of brushes attached to the at least one broom channel, the forward row of brushes extending longitudinally from the first side of the at least one broom channel to the second side of the at least one broom channel;an aft row of brushes attached to the at least one broom channel such that the aft row of brushes is spaced apart from and rearward of the forward row of brushes relative to the coupling mechanism to allow infill of the synthetic athletic field to flick upward from the forward row of brushes while containing the infill for re-agitation from the aft row of brushes when the grooming apparatus is being pulled across a synthetic athletic field, the aft row of brushes extending longitudinally from the first side of the at least one broom channel to the second side of the at least one broom channel;wherein at least one of the forward and aft rows of brushes includes a pattern of alternating bristle height sections comprising alternating short bristle sections and long bristle sections oriented diagonally to prevent infill material buildup in front of the brushes;wherein the coupling mechanism and the frame are configured such that when attached to a vehicle and being pulled across the synthetic athletic field, the vehicle can control a downward pressure forcing the forward and aft rows of brushes into contact with the synthetic athletic field. 2. The synthetic athletic field grooming apparatus of claim 1, and further comprising a drag mat mounted behind the forward and aft rows of brushes and configured to level infill material. 3. The synthetic athletic field grooming apparatus of claim 1, and further comprising a tine support plate assembly coupled to the frame forward of the at least one broom channel and the forward and aft rows of brushes, wherein the tine support plate assembly includes a plurality of tines with adjustable heights, angles and pressures configured to loosen and pull up compacted infill in the synthetic athletic field when the grooming apparatus is pulled by a vehicle across the synthetic athletic field. 4. The synthetic athletic field grooming apparatus of claim 3, wherein the plurality of tines are configured to retract if the synthetic athletic field grooming apparatus is moved in a reverse direction such that damage to the synthetic athletic field is prevented. 5. The synthetic athletic field grooming apparatus of claim 3, and further comprising at least one magnet mounted between the plurality of tines and the forward row of brushes to collect metallic or magnetic debris flicked upward by the plurality of tines, wherein the at least one magnet is mounted at a height such that it cannot contact the synthetic athletic field as the grooming apparatus is pulled by the vehicle across the synthetic athletic field. 6. The synthetic athletic field grooming apparatus of claim 5, and further comprising a deflector positioned forward and above the at least one magnet to guide the metallic or magnetic debris into the at least one magnet. 7. A synthetic athletic field grooming apparatus configured to be pulled by a vehicle across a synthetic athletic field for use in maintaining the synthetic athletic field, the synthetic athletic field grooming apparatus comprising: a frame having a coupling mechanism at a front of the grooming apparatus for mounting the grooming apparatus to the vehicle;at least one broom channel coupled to the frame rearward of the coupling mechanism and extending longitudinally from a first side of the at least one broom channel to a second side of the at least one broom channel;a forward row of brushes attached to the at least one broom channel, the forward row of brushes extending longitudinally from the first side of the at least one broom channel to the second side of the at least one broom channel;an aft row of brushes attached to the at least one broom channel such that the aft row of brushes is spaced apart from and rearward of the forward row of brushes relative to the coupling mechanism to allow infill of the synthetic athletic field to flick upward from the forward row of brushes while containing the infill for re-agitation from the aft row of brushes when the grooming apparatus is being pulled across a synthetic athletic field, the aft row of brushes extending longitudinally from the first side of the at least one broom channel to the second side of the at least one broom channel;at least one spray boom coupled to the frame rearward of the aft row of brushes, and at least one spray nozzle mounted on the at least one spray boom and configured to spray an anti-static solution on the synthetic athletic field to prevent the infill material from sticking to blades of the synthetic athletic field, wherein the at least one spray nozzle comprises at least one forward spray nozzle and at least one aft spray nozzle positioned rearward of the at least one forward spray nozzle, wherein the at least one forward spray nozzle is positioned closer to the aft row of brushes than is the at least one aft spray nozzle such that the at least one forward spray nozzle and the at least one aft spray nozzle spray the synthetic athletic field with blades of the synthetic athletic field being at different angles relative to vertical;wherein the coupling mechanism and the frame are configured such that when attached to a vehicle and being pulled across the synthetic athletic field, the vehicle can control a downward pressure forcing the forward and aft rows of brushes into contact with the synthetic athletic field. 8. The synthetic athletic field grooming apparatus of claim 7, wherein the at least one forward spray nozzle and the at least one aft spray nozzle are spaced along a width of the apparatus and are adjustable to allow adjustment of distances between spray nozzles to provide an adjustable spray pattern. 9. The synthetic athletic field grooming apparatus of claim 7, wherein the aft row of brushes is an aft-most row of brushes of the synthetic athletic field grooming apparatus with no brushes rearward of the aft row of brushes or between the at least one forward spray nozzle and the at least one aft spray nozzle. 10. The synthetic athletic field grooming apparatus of claim 7, wherein the at least one spray nozzle comprises the at least one forward spray nozzle and the at least one aft spray nozzle with no brushes positioned between the at least one forward spray nozzle and the at least one aft spray nozzle. 11. The synthetic athletic field grooming apparatus of claim 7, wherein the at least one spray nozzle comprises the at least one forward spray nozzle and the at least one aft spray nozzle both positioned rearward of all brushes of the synthetic athletic field grooming apparatus. 12. The synthetic athletic field grooming apparatus of claim 7, wherein the at least one forward spray nozzle and the at least one aft spray nozzle are mounted on the at least one spray boom at an angle greater than zero relative to vertical.
