BACKGROUND OF THE INVENTION The present invention relates to a cutting machine, in particular for construction waste and demolition materials, with crushers in the form of a rotor rotated in a housing, preferably with hammers that are swivelingly suspended, and a feed device for feeding the material to the rotor.

Such a cutting machine is described in U.S. Patent No. 3,825,192, which includes a jaw crusher with a chain conveyor. The disadvantage of this is that mechanical malfunctions often occur, while the end product is not reassuring and there is no possibility of direct recycling.

It is an object of the present invention to provide a cutting machine which disintegrates particularly finished concrete slabs, such as floor coverings, into its mineral and metallic components, while providing the mineral residues as filler with the same grain composition for reuse.

The solution to this problem is based on the recognition that by adjusting the hammer's swinging suspension hammers relative to the anvil, simply adjusting the cutting machine to create any particle size of the objects to be shredded. This solution can be accomplished, as a complement to the task, by providing the dispensing device, which feeds the material to be crushed onto the anvil, with two superimposed endless belts wrapped around two diverting rollers, of which the upper belt slant is adjustable and adjustable. The invention thus fulfills the additional function.

-3determines that the material to be shredded is of constant conductivity so that the set mesh size does not change. This is also facilitated by the fact that the height of the two rollers of the upper endless belt can be independently adjusted. In the US patent mentioned in the introduction, the upper conveyor belt is pivotally mounted about an axis about half its length, i.e., if the position of the lower deflection roller changes, the upper is also forced in the opposite direction. In the present invention, when the upper web is adjustable on a roller, the slip is reduced, thereby providing a constant supply of material to be shredded. In addition to the adjustment possibilities of the present invention, the clamping force by which the belt presses on the material to be conveyed can also be adjusted, thus enabling individual handling of the various materials.

The hammer rotor of the machine can be swiveled around a lower shaft in the housing. When tilted, the rotor axes are guided by a circular groove on the housing wall. This makes the machine easy to adjust when hammers wear. This adjustment can be done by means of a piston and a locking nut. And if the anvil is worn out, it is pulled out of the housing and turned 180 degrees, then retracted to bring the anvil back into service. The housing of the machine can be spared by providing a separate liner for the wall of the housing in the vicinity of the pop-up pieces. A further advantage is that the lower roller of the upper dosing belt is guided by a circular groove with a radius from the center of the rotary hammer.

Thus, the present invention provides a cutting machine capable of cutting construction waste and demolition materials in particular by driving hammer bodies which are pivotally suspended on a rotor located in the housing, and wherein the dispensing device is capable of delivering the dispensing device to the anvil. distance can be changed.

The main parts of the cutting machine are crusher B and dispenser C, which are housed in housing D.

The dispenser comprises the following main parts: an infinite conveyor belt 7 below, an infinite friction belt 1 above which generates a gap in the conveying direction towards the conveyor belt 7 and which is led by the guide rollers 13 and 14. The conveyor belt 7 is supported by the guide rollers 8 and 9, where the guide roller 9, which is closer to the crusher B, is driven at its drive shaft 15. The 1 scraper-5 ♦ · ·

two conveyor chains 16 (Fig. 2) are disposed in a mirror image relative to the longitudinal axis and connected to the gears 17 mounted on the drive shaft 5 and 15 respectively. The drive shaft 5 is guided by an arcuate groove 11 having a center centered on the axis of the crusher B, so that the deflection roller 14 can be adapted to the thickness of the plate 39 or similar to the crusher B. The height of the guide rollers 13 and 14 can be adjusted by the hydraulic cylinders 18 and 22, the piston rods 19 and 23 of which are connected to the shaft 26 and the drive shaft 5 of the guide rollers 13 and 14 through the triangular shaped lever 20 and 24 respectively. implemented. As stated in the

2, the hydraulic cylinders 18, 22 and the piston rods 19, 23, as well as the angular lifters and straps 25, 4 are arranged in pairs at the ends of the shaft 26 and the drive shaft 5 projecting from the housing D. FIG. The angle lifts 20, 24 are pivotally mounted about the axes 21 and 3. The crusher B is designed as a rotor on the drive shaft 27, which at each end protruding from the housing D is supported by pivoting flaps 30, which are pivotally mounted on the pin 38 around the base of the housing D. On the drive shaft 27, the disc segments 28 of Fig. 4 are mounted at a defined distance to which hammers 29 made of highly abrasion-resistant castings and highly insensitive to foreign bodies are suspended in a swinging arrangement about the axis 31.

• ·

As shown in Figure 5, the disc segments 28 follow a pair of rotations 90 degrees relative to each other on the shaft where the hammers 29 are suspended between a pair of segments. Optionally, three consecutive sets of hammers 29 rotated 90 degrees are shown, with hammers of the same angle aligned in a row. The width of the hammer 29 is approximately 120 mm, and a pair of blinds 33 corresponding to the width of the hammer is disposed between each of the disc segments 28. The rotary hammers 29 are successively rotated but spaced 90 degrees in succession, as shown in Figures 5 and 6, each being displaced axially by a rotor width. As the rotor and crusher B is rotated, three adjacent 29 hammers simultaneously strike the material to be crushed, thus breaking it into four parts in a row. In the line of the hammer 29, the plate 39 rests on the anvil 6, which rests on the optional holder 34 of rectangular cross-section and formed in the housing D so that it can be pulled out along its longitudinal axis and retracted about its centerline. This allows the anvil 6 to be worn out when it is tapped by the breaker (indicated by a dotted line in Figure 1) and retracted from housing D and rotated 180 degrees, i.e. an unused edge opposite the worn edge available. Similarly, the hammer 29 can be flipped because if its ratchet edge is worn - as indicated by the dotted line here - it can also be turned 180 degrees when suspended between the disc segments 28.

The crusher B is driven by the electric motor 35 by the multiple V-belts 36 by the V-belt 32 mounted on the drive shaft 27. The drive shaft 27 may move in a groove 37 having a radius extending from the center of the pin 38 of the housing D. The piston 45 of the hydraulic cylinder 10, which is pivotable about the pin 12 and connected by the piston rod 44 to the flap 30 (Figs. 1 and 8), can be used to adjust the crusher B along with the drive shaft 27. The pressure on the piston 45 is related to the degree of wear of the hammer 29, i.e. when the hammer is new, the piston 45 is in its rearmost position, and when the wear of the hammer 29 increases, the piston 45 (Fig. 8) moves in this direction. In the most worn position of the hammer 29, the piston 45 is pushed forward completely and deflected by the nut 42, which is screwed onto the threaded end 43 of the piston rod 44 extending from the cylinder 10. The nut 42 abuts the sleeve 46 welded to the ring 47 supported on the end face of the cylinder 10. The starting rotation of the hammers 29 is indicated by the dotted circle U. By adjusting the nut 42, it is possible to adjust the allowable wear of the hammers 29.

The cutting machine according to the invention operates as follows when crushing the sheets:

The sheet 39 is fed by a dispensing device (not shown here) to the conveyor belt 7, which extends to the friction belt 1, the leading edge of which is adjusted so that the conveyor belt 7 and the gap between the friction belt 1 corresponds to the thickness of the sheet, so that when it enters it, it is led to the crusher B. As already mentioned, the friction belt 1 is infinitely adjustable and runs at the same speed as the transfer belt 7. The retracted plate 39 is thus pressed into the anvil 6 and extends into the area of the hammers 29. The hammers 29, by virtue of their arrangement described above, make a continuous cut, wherein the individual cut width corresponds to a hammer width of 120 mm in the particular embodiment.

Adjustment of crusher B due to the wear of the hammer allows the crushing condition to be always optimal in the area of the anvil 6. Here, the hammers 29 have a working width of 1440 mm. This breaks the strip across the entire width of the sheet at each turn. The offset arrangement of the hammers allows for helical machining of the plates. The desired mesh size of the broken material can be set by adjusting the circumferential speed or by changing the feed rate of the material to be cut.
