Abstract

1. Machine for the shredding of garden refuse such as twigs and foliage of shrubs or the like, with a filler opening (17), formed by a hopper (12) preferably at the upper end of the housing (11), and a discharge opening (15), preferably located at the lower end of the housing (11), and a motor-driven means, arranged between them and formed as an ellipse-shaped rocking disc (21, 22), xhich is secured on a rotatively supported drive shaft (18) and on the circumference of which cutting edges (23) are formed, which cooperate cuttingly with a cylindrical inner wall of the housing (11) characterised in that to both sides of the rocking disc (21, 22) part-cylindrical metal bands (29, 30) are secured on the housing (11) spaced from the vertical mid-plane (centre line), which metal bands are formed open in a downward direction and of which the opposing longitudinal edges form the cutting edges (30a).

Preferred embodiments of the invention are shown in Protection claims included. The scope of protection extends not only to the claimed individual features, but also to also on their combination.

An embodiment of the invention is shown in the drawing and will be described in more detail below Show it:

Pig.l is a perspective view of the machine; Fig. 2. a longitudinal section through the machine;

3 shows a cross section through the machine according to the line III-III of Figure 2;

4 shows a perspective illustration of an opposite one fastened to a drive shaft 2 modified swash plate;

Fig.5 'is a perspective view of an opposite Fig. 2 modified sheet metal strip.

The machine for shredding garden waste consists of a housing 11 held by four supports 10

a funnel 12 is arranged on the top. The housing .11 is of a jacket 13 ,. which in cross section has the shape has an inverted U and has two congruent end walls 14 which are welded to the jacket 13. On the underside of the housing 11 this is open to the outside via an outlet opening I5, while on the Top of the shell I3 via an opening 16 a connection of the inner cavity of the housing 11 with the funnel 12 and is created via the upper filler opening 17 with the outside.

■ Inside the housing 11 is a horizontal one in the longitudinal direction Drive shaft 18 is arranged, which is mounted in bearings 19 of the two end walls 14. One outside the case 11 extending stub of the drive shaft 18 is connected to 'a drive motor.

A swash plate 21, 22, which is an elliptical disk inside the housing, serves as the cutting tool of the machine 11 attached between the funnel 12 and the outlet opening 15 on the drive shaft 18, for example . is welded on. According to FIG. 2 of the drawing, the plane of the swash plate 21 is in relation to the axis of the drive shaft 18 at an acute angle, so that material filled in via the hopper 12 as the drive shaft 18 rotates from the swash plate 21 is provided with a movement, welehe has a horizontal component running in the direction of the axis of the drive shaft 18. The material will thus conveyed to the outer edges of the elliptical swash plate 21 designed as cutting edges 23, where it resting against the inner surface of the housing 11 :: he.

is cut.

According to Figure 4 of the drawing, the outer edges are not the swash plate 22. formed as cutting edges, but ■ This disc has on its surfaces and on its circumference grooves 24 and 25, in which cutting blades 26 are inserted and fastened with the aid of screws 27. The cutting blades 26 have cutting edges 28 in the area the outer edges of the swash plate, so that this swash plate 22 when the drive shaft rotates 18 carries out its task of cutting up.

Inside the housing 11 are on the inner surface of the shell 13 on both sides of the swash plate 21 or 22 metal strips. 29 and 30 are arranged, which surround the cutting edges 23 and 28 of the swash plate 21 and 22, respectively. These Sheet metal strips made of hardened steel work with their dew facing edges also as cutting, the sheet metal strips 29 according to Figure 2 of the drawing here are provided with special cutting tips 31. In your In the lower area, the sheet metal strips 29 and 30 are attached to wedges 32 which are attached to the inner surface of the jacket 13 attached ,, for example welded. The sheet metal strips 29 and 30 have fastening bores 33 for this purpose through the screws screwed into the file 32 34 are passed through.

The area of the elliptical swash plate 21, 22 corresponds to the area of the cylinder section of a circular cylinder with the radius of the shell 13 along the swash plate plane, so that the outer edges of the swash plate 21, 22 always rest on the inner surface of the jacket 13 in its curved area and there their cutting movements can perform.
