Abstract

In the case of a mobile soil loosening device, a tool rocker (26) carrying the tools is provided, the front lever arm (36) of which has diametrically mounted follower rollers (38) which run on the inner wall of a rotary pot (46) which, with adjustable eccentricity, is connected to the PTO shaft ( 16) of the towing vehicle connected base plate (48) is carried. A rubber layer is installed between an outer wall and an inner wall of the rotary pot to dampen noise and vibrations.

Description

Rotary pot 46 can be fixed in different eccentric positions by means of adjusting screws 52

The follower rollers 38 lie above and below the inner wall 56 of the rotary pot 46 and run on it, constant rolling contact is guaranteed due to the diametrical arrangement

The inner wall 56 is designed as a cylinder ring and between this inner wall 56 and the rigid outer wall 54, which is connected to the bottom plate 60, is located a rubber layer 58, the task of which is 10, with the following rollers 38 resting as closely as possible to absorb the transverse forces on the inner wall 56. aside from that This dampens shock loads and the noises that occur
