Mulch flails, preferably for shredding vegetable materials for composting purposes

The innovation relates to a mulch stick according to the preamble of the main claim, in particular for the special uptake and shredding of plant materials, primarily suitable for composting purposes should be.

From DE-GM 84 19 526 is already a flail shape known specifically for this purpose, the

a. is designed as a so-called blunt-edged hammer that

b. perpendicular to the hub axis has the Torrn of a circular sector, where

c. the hub on both sides over the hammer

protrudes and

d. the entire toilet is a drop forging made of alloyed structural steel.

Such a mallet is intended to be used for composting organic waste in such a way that the waste to be processed is comminuted in such a way that the fibers, in particular wood fibers, are extremely beneficial for the following The rotting process to be unlocked. For this purpose, the fibers should mostly not be cut, but rather smashed and are crushed, mainly cutting mulch flails are allegedly not suitable for this.

The aim of this known training is therefore to create a Scfilegel which enables a predominantly beating and squeezing crushing of the organic waste to be prepared for composting, and this in particular through its blunt-edged hammer head ends should reach.

The task and the technological background are recognized correctly in this previously mentioned publication, however, the structural features proposed as a solution for this are not only functionally completely unsuitable to achieve the intended purpose, but also fundamentally wrongly interpreted in terms of their actual effect. For example, a blunt-edged hammer produces never show a fraying of woody materials, but at most their kinking, quite apart from the fact that such hammers also have no safe reception at all d-s normally enable goods lying flat on the ground.

The present innovation therefore has the task made to create a mallet that is actually and optimally suitable for composting in all work phases and solves this problem with the protection claims specified structural smock and measures in accordance with the regulations.

The drawings show two alternative Ausführungsfeeispiele of the innovation in various views and although Figures 1 through 3, the basic embodiment, Fig 4 to 6 an Al "i ternative thereto, and Figure 7 in a reduced representation of the |;... Schematic principle of a working shaft with neuerungsge-

f. mäßsn mulch flails. <

The two embodiments illustrated in the drawings have been known flails as a common significant basic feature a seen from the side asymmetrically constructed impact member 2 and facing a gelumlauf from the body center axis "x" out in Schle direction "F" 2a over all, a shovel excluded wolbten Riving knife 3 or 3a. In addition to a good absorption and conveying effect, the basic shape does not result in any cutting shredding, even with short mulched material, but rather a kind of splitting in the longitudinal direction of the fibers, due to the respective wedge tips 8 and 8a.

Since with these innovations according to the invention it is also provided that the underside 4 or 4a of the riving knife 3 or 3a directed towards the ground "E" is roughly curved and has a greater curvature, ie a smaller radius "R" than the radius "R." measured from the secondary center point "P" of the Schlegeldurchechwingkreisee "S" on its storage

bolt 5 or its guide rod in the working shaft 6, creates a clearance angle "a" to the ground "E" on the bottom of the flail, which not only significantly reduces the working resistance, but also causes constant automatic re-sharpening of the riving knife β or 8a will. In a further special embodiment of this innovation, there is also an additional wear strip 7 or 7a attached at least centrally in the circumferential direction "F" to the flail body on the impact part 2 or 2a, this so-called wear strip from the preferably with a slight radius ¹¹ R ₉ " provided tip 8 or 8a of the riving knife 3 or 3a from »runs counter to the direction of rotation of the flail" F "rising towards the rear.

The three-dimensional shape features described above can be implemented on flail bodies in welded (Fig. 1 to 3) or GuQ or drop forged construction (Fig. 4 to 6) with or without an additional application of high-strength steel alloys 10 on the scoop-shaped surface 11 of the Riving knife 3 or 3a. Purely structurally and less functionally, there are rounded "Rx" of all structural or shaping material transitions in the welded (Tig. 1 to or cast or forged construction (Fig. 4 to 6)) of the entire mallet body.
