Description

Title: Device for crushing materials, especially wet clay

The invention relates to a device for crushing materials, in particular, but not exclusively, for crushing wet clay delivered from the extraction site by truck.

The invention is based on a device as specified in the preamble of claim 1 and has been used for decades for shredding plastics, paper, cardboard, chipboard waste, pallets, etc.

Known devices of this type, including those for crushing wet clay, require a buffer device, with which the filling hopper is fed. Such a buffer device can be, for example, a box feeder or conveyor belt and is necessary in the known generic devices due to the relatively small capacity of the filling hopper and increases the manufacturing costs of the devices.

The invention is based on the object of designing and arranging a generic device in such a way that it can be fed directly with a truck, wheel loader or crane system and can be manufactured more cost-effectively.

This object is achieved by the

Characteristic features of claim 1 are solved, whereby an expedient further development of the invention can be found in the dependent claim.

The device according to the invention can be easily fed without a buffer device, since the material to be shredded is tipped directly from a truck into the filling hopper

The device is relatively compact and therefore requires little floor space and can be manufactured at relatively low cost.

An embodiment of the invention will now be described with reference to the drawing. Here, simplified schematically shows

Fig. 1 a front view and

Fig. 2 is a side view of the device.

The device 1 for shredding material sits on a support frame 2 and has a feed hopper 3, a shredding chamber 4 arranged underneath, a roller-like rotor arranged to the side of the shredding chamber 4 and a slide 6 which can be moved back and forth in the shredding chamber 4 up to the rotor 5 and which presses the material 12 to be shredded (Fig. 2) against the rotor 5. The rotor 5 is equipped in the usual way with exchangeable shredding tools (not shown) and is rotated about a horizontal axis 8 by an electric drive 7. The feed hopper has a capacity of about 20 m ³ , for example.

The upper edge 9 of the filling hopper 3 is approximately at the level of a surface or ramp 10 on which a truck 11 can drive up to the filling hopper 3 and tip its load into it, as shown in Fig. 1.

The material 12 to be shredded (see Fig. 2) normally slides into the shredding chamber 4 and is pushed there by the slide 6 towards the rotor 5. With moist clay, it can occasionally happen that the material 12 is compressed in the hopper. To prevent this and to loosen the material, another slide 13 is arranged directly above the slide 6. The other slide 13 can be moved back and forth in the upper area of the shredding chamber 4.

Both slides 6 and 13 are guided linearly via rollers (not shown).

The shredded material can be removed via a conveyor belt 14 for further processing.
