Abstract

A cutter built into a rectangular large bale press consists of cutters (C) projecting axially from the bottom of the press piston (A), which are forced into the bale (B) with each stroke of the piston (A), where they cut the bale transversely. The cutters are so arranged that they do not cut the bales upper and lower parts by at least ten centimetres, as well as sideways, outside the outer binding cord. USE/ADVANTAGE - The bales retain their original bound and pressed form.

Description

State of the art

In the balers currently used in the harvesting of straw, which work according to the extrusion process (piston presses), During the pressing process, individual packages go through pressed each butt to a compact bale. More used in recent years Rectangular large balers leads to the fact that relatively large individual packages pressed into a rectangular large bale become. These big single packages are but difficult and to dissolve with increased effort.

problem

The invention defined in claim 1 is the problem based on creating a cutting unit during the pressing process the relatively large individual packages of the entire bale Layer by layer in the transverse direction cuts. The depth of the knives with which the individual layers must be pierced, must be such that Each layer is safely pierced (about 10-15 cm).

Achievable benefits

The advantage achieved by the invention is that the entire bale is easier to dissolve.

Further embodiment of the invention

The further embodiment of the invention according to claim 2 to 4 has the advantage that the bale in its pressed and bound form does not decay and its original shape reserves. Only after the slicing of the binding yarn disintegrates the bales and can be processed easily.

The claim 5 allows a smooth and constipation-free Filling the Preßkanales by the conveying organs to ensure.

The claim 6 allows the cutter without large Problems and without making major changes to the machine, can be installed in the press. Farther You can also use presses already on the market be retrofitted to this cutting system.  

Presentation of the invention

An embodiment of the invention will be explained with reference to FIGS. 1-4:

The explanation is based on the following bale size placed:

Width: | 120 cm Height: 70 cm

The length is irrelevant of the bale is tied 6 times, Distance between the twine systems: about 20 cm.

It shows

Fig. 1: plunger with attached knives in retracted position (side view).

Fig. 2: plunger in the fully extended position with pressed into the material to be pressed knives (side view).

Fig. 3: plunger in the compression channel, with applied knives (top view) and recorded, imaginary position of the binding yarn (dashed line).

Fig. 4: punctures of the knife in a pressed bale with position of the binding yarn and not cut lots (top view).

In Figs. 1 and 2, the principle of the cutting unit is shown. The on the bottom of the plunger (A) mounted knife (C) pierce it during the pressing process in the pressing channel located in the pressing (B) and thereby divide layer by layer of the bale.

The chamfered shape of the knives (C) can be recognized by a trouble-free filling of the Preßkanales by the conveying organs to ensure in the delivery channel (D).

Fig. 3 shows the distribution of the knife (C) on the plunger bottom. It can be seen from the subdivision of the knife in the vertical direction, as well as the staggered arrangement in the transverse direction.

Furthermore, it is the location of the knife between the (imaginary) Locations of the binding yarn (E) to recognize.  

Fig. 4 shows the punctures of the knife ( 1 ) in the pressed bale between the layers of the binding yarn ( 2 ). Furthermore, the non-cut parts (about 10 cm) at the top and bottom (a) and laterally outside the outer Bindegarnlagen (b) can be seen.

In addition to the illustrated example of about 120 cm width and about 70 cm high, this cutting system can also be used by others Bale dimensions are installed. The number of knives is aimed depending on the height and width as well as the number the bindings of the individual bale formats.

This cutting system has the advantage that it worked with it Rectangle large bales easier to dissolve and process let, without thereby the bales in its pressed and bound form disintegrates.

Furthermore, this cutting system is relatively easy in Install balers, as well as already on the Market located presses to be retrofitted.

Claims (6)
