Description

Crushing machine for field and garden products The invention refers to a shredding machine specifically designed for kitchen use with rotating knife roller. In order to achieve an extremely fine division of the food achieve, are according to the invention between the in their composition the roller Forming disks circular knife blades with beak-shaped protruding over the disks Approaches switched through slots in the bottom closed off by the roller of the machine housing. Knife blades protrude from the housing in circumferential slots of the disks recessed in the form of cells, which are those of the knife blades continue the crushing work done. The knife blades are re their depth of penetration adjustable, depending on the degree of fineness of the cutting process to be able to change according to the product to be cut.

In the drawing is an embodiment of the subject matter of the invention for example illustrated.

Fig. R is a cross-section through the shredding machine.

Figure 2 is a top plan view of this with the lid removed.

Fig. 3 is a longitudinal section along the line A-B of Fig. R.

Fig.q. shows a detail.

In the housing g, which is provided with a cover t and is square in the upper part and barrel-shaped in the lower part, advantageously made of porcelain, there is the longitudinally continuous knife roller composed of disks b and closes an opening c of the bottom formed by pulling in two opposing walls dl, d '. The individual disks b have cells' e in their surface area and circumferential slots f extending through them. Between the individual disks b there are circular knife blades da with beak-shaped tips hl protruding from the edge (see in particular Fig. The bottom parts dl, d = have curved slots il, i ' after the center of the roller for the passage of the beaks hl of the knife blades h and are curved on the lower surfaces so that the disks b of the knife roller can rotate close to it. The disks and knife blades are slidably placed on a shaft k penetrating the housing g with a groove m 'and a spring m. The shaft k , secured by a wing nut n and guided in a plug-in cover j , receives the hand crank o on its protruding square pin Q. In a shaft r of the floor filling is a knife chimney s, whose 'individual blades fit into the circumferential slots f of the discs b and whose web q is adjustable by means of screw spindle v and knurled nut w so that the depth of engagement of the blades can be changed. So that the blades.r can be cleaned easily, they are lined up on a pin .1- which pulls through the bar q. An at least elastic scraper y, which is made of rubber or the like and which is attached to the inside of the curvature of the lower part of the housing and has slots z for the passage of the beak tips lt ', protrudes into a cell e, around them individually as they pass by to clean any remaining material to be cut.

The cut material introduced into the upper part of the housing g slides on the bottom part d2 in front of the beak tips hl and is supported by these when rotating cut through the knife roller in the direction of the arrow (Fig. i) with a pulling cut. The sections, as far as they are not held back by the sharpened edge of the bottom part d2 and then later divided, fall into the cells e of the disks b and become brought in front of the knife blades, through which they experience a further division, to then get into the lower part of the housing. Something left in the cells Particles of the material to be cut are swept out by the fluttering scraper y, z. In any case the material to be cut experiences through the double processing by means of the cutting tools so extensive that a very fine end product is obtained. This is why the machine is particularly suitable for cutting onions, for example.

To clean the machine, the comb q, s is pulled back so that the blades release the knife roller, 'the nut n loosened and the roller with the Cover j and the shaft k taken out together from the housing g.

Claims (1)

PATENT CLAIMS: i. Shredding machine with rotatable knife roller for field and garden products, especially for kitchen use, characterized by knife blades (la) with beak extensions (h1) between the discs (b) of the knife roller and in circumferential slots (f) that pre-shred the material above the bottom (d2) of the filling funnel Knife blades (s) stepping on the disks under the base (d2) for re-shredding, as well as cells (e) in the area around the disks, in which the pre-shredded material is fed to the knife blades. z. Crushing machine according to claim i, characterized by a funnel-shaped narrowing of the housing (g) and slots (il, i2) in the funnel walls for the passage of the beak-shaped scraper blades (V) of the knife blades (h) entering the mouth of the funnel (d1, d2) . 3. Crushing machine according to claim i and z, characterized in that the undersides of the funnel walls (dl, d2) are curved towards the surface of the discs (b) of the knife roller, at which it can rotate past precisely. Comminution machine according to claims i and 2, characterized by a knife blade comb (s, q, v, w) which can be displaced perpendicularly to the knife roller and adjustable with regard to the insertion depth. 5. Crushing machine according to claim .4, characterized in that the blades (s) are detachably fastened in the web (q) of the comb, for example by means of a push-through pin (x). 6. Crushing machine according to claim i, characterized in that the disks (b) and the knife blades (1z, h1) located between them are longitudinally displaceable on a hand crank shaft guided in an end cover (j) of the housing and secured outside the same by a nut (s) (k, o) are lined up. 7. Comminuting machine according to claim i, characterized by an elastic scraper (y) with slots (z) for the passage of the knife blades (h, h1), which grabs a cell (e) of the disks (b).
