Device for making ground firm for earth preparation and pre seeding - has one or more stamping elements rotatably mounted on horizontal axis and having radially protruding stamping surfaces set spaced around circumference

摘要

The stamping element used is mounted and rotates on a horizontal axis and protrudes radially outwards. It's cross section changes radially from the inside, where it is a stamp part (21), to the outside, where it is a stamping body (26). On the exterior circumference (20) are several working surfaces (27), these project a greater surface area in the radial direction for the stamping body than the cross sectional surface of the stamp part. The distance between two elements set axially on an axis is the same or greater than the distance between two stamp parts around the circumference. The horizontal axes are connected and driven together by chains or cardan links. USE/ADVANTAGE - It is trouble free to work and is effective even on sticky ground and prevents sticking of the work surfaces and the chambers in between the work surfaces.
