DITCHING DEVICE FOR GOLF YARD DRAINAGE DITCH AND DRAINAGE DITCH STRUCTURE THEREOF

摘要

PURPOSE: To perform development of a ditching device for a drainage ditch in a golf yard and to perform improvement of drainage efficiency. ;CONSTITUTION: In a traction vehicle having a three-point link mechanism 3, a main lever 11 is arranged to a rear, a support lever 14a is laterally extended, and a shearing blade 16 from which a longitudinal lever 15 is suspended is pivotally mounted on each of the tips thereof. Meanwhile, a ditching blade 25a is attached to a part of the main lever 11, a ditching body 26a is attached to the tip thereof, and a filling case 29a in which pebbles can be loaded is connected to a rear. Rotary shafts 18 are pivotally mounted on ends across the support lever 14a and a shaft gear 19 interlocking with a prime motor is mounted. Meanwhile, a transmission belt 23 is run about a driven gear 22 and a drive gear 21 extended to the shaft of the shearing blade 16 to forcibly rotate the shearing blade 16. Further, a cutting blade 29a to cut the root of lawn grown at the side of the drainage ditch to promote reticulate growth is rotatably mounted on the tip of the longitudinal lever 29. As a result, a drainage ditch is simply ditched, a balance between water feed and drainage is kept, and the drainage ditch through which drainage in quantities is effected is ditched.;COPYRIGHT: (C)1994,JPO&Japio
