Device for the mixing of compost

Abstract

A mobile device for turning over or mixing accumulations of organic waste materials, such as compost at fixed dump sites, having a steerable chassis with working tracks enabling it to advance through the accumulations of material. The device has a mechanism for mixing the waste picked up while it drives through the waste, and after being thoroughly mixed, redepositing the waste behind the device. The device includes a clearing mechanism disposed on the front side of the chassis and in the area in front of each of the working tracks of the chassis, for clearing a track path as the chassis moves through the waste material. The clearing mechanism avoids the need for laying down separate tracks and comprises a mixing mechanism with a guide shield disposed in front of the intake in the mixing mechanism and clearing tools disposed on a guide surface with the mixing mechanism. The clearing tool has a disk which is driven by a drive element, such as a hydraulic motor, for rotating the disks in front of the guide surface so that excavating projections, which are provided on the disks, clear a path in front of the chassis and move the waste material into the space between the tracks so that it can be picked up mixed and redeposited behind the device.
