Title: Belt-type lawn sending apparatus
Inventor: AOYANAGI TORU
IPC: A01C11/02
Filed: 1993-11-18
Abstract: PURPOSE:To provide an apparatus capable of automatically sending out a mat- like wound lawn with a driving apparatus of small output and spread the lawn all over the ground. CONSTITUTION:A carriage 5 of this apparatus travels by labor and at the same time the second long-sized pulley 21 is rotated by the power derived from a driving apparatus 39 via sprockets 41, 35 and a chain 37. By this motion, the first long-sized pulley 19 and an endless belt 23 rotate together. A roll-shaped lawn 1 placed on the belt is made to rotate by the motion of the belt and send itself to the ground to spread it all over the ground. Here, since the power transmitted from the belt 23 to the roll-shaped lawn 1 acts at its peripheral parts, large torque is generated with small power and accordingly a power source of small output is enough as the driving apparatus 39.
