Agricultural fertilizer spreading device, comprising adjustable transmission units at least at some of spreading disks

摘要

The device is assembled of a storage container (2) on a frame (1), quantity measuring devices (5), and several rotating spreading disks (6). Each of the disks (6) is attached to a transmission shaft (8) accommodated in a housing (10, 11) and driven by a central transmission unit (13) connected to the PTO (14) of a tractor. In order to facilitate the disks (6) located at one side of the device to move at different speed levels a transmission unit (10) designed as a CVT working with chains (16) as transmission elements and controlled by the onboard computer is added to the system.
