description

DJ .η invention relates to a mobile crushing plant comprising a provided with at least one wheel set chassis and their between a raised operating position and a lowered traveling position up and abschwenkbarer feed hopper with the feeder conveyor at one end, and the size reduction machine with Vorabsiebeinrichtung and a dispensing device located below it are arranged in their operating position offset in the longitudinal direction to the wheelset provided at the other end of the chassis.

The known shredding systems of this type are usually arranged on semi-trailer chassis, but it is it is also possible to use other chassis for them, for example with a steerable front wheel axle (DE-OS 16 07 502). The shredding machine is generally located somewhat in front of the wheel set of the chassis because the shredded material is the Crushing machine leaves down and therefore the facilities required for the delivery of the goods are provided there must be and the wheelset would stand in the way if the shredding machine were placed above it. A higher one Arrangement of the shredding machine on the chassis in such a way that these devices are also arranged above the chassis frame is not possible due to the high center of gravity and the maximum height in road traffic.

With the arrangement of the shredding machine in front of the wheel set, however, there is also a considerable proportion of their weight the front end of the chassis and thus on the steering axle or on the semi-trailer, which is undesirable and possibly whose load-bearing capacity exceeds, because, in addition, the weight of the other parts of the crushing system, such as in particular the usually very large feed hopper, which is equipped with a heavy apron conveyor, is a burden. Also becomes the burden

possibly not evenly distributed over the wheels of the wheel set, so that the wheel pressure permissible on public roads is exceeded for individual axes.

The object of the invention is the steering axle or the semi-trailer To relieve the weight of the shredding machine as completely as possible and as completely and evenly as possible to let come on the axles of the wheelset of the chassis, which are adapted to the weight by appropriate training can. This is achieved according to the invention in that the shredding machine on the chassis in its longitudinal direction between its operating position in front of or behind the wheelset and a driving position can be moved back and forth over the wheelset. For this purpose, the shredding machine is separated or detachable from the one that is fixedly arranged under it in the chassis in the operating position Dispensing device provided.

With an arrangement of the shredding machine in the operating position Behind the wheelset, the shift before the start of travel via the wheelset is mainly used for uniform movement Load distribution on the axles, e.g. B. when the task device is easy to carry out.

The shredding machine, which is arranged on slide rails or rollers for this purpose, is moved back and forth by means of a hydraulic cylinder-piston unit, which is located between the rear end of the chassis and the shredding machine is arranged. It is advantageous if such a unit is provided on both sides of the chassis.

Together with the shredder can be on a common The frame of the drive motor and the pre-screening device can be arranged. The drive motor is preferably with With respect to the chassis behind the shredding machine, and the frame is central and in its area narrower than in the area of the shredding machine, so that the two hydraulic cylinder-piston units that are in the area

attack on the frame of the shredding machine, arranged next to it on both sides can be grounded.

According to a further embodiment of the system according to the invention, devices are provided through which when moving back and forth the shredder the feed hopper is moved up and down. As is well known, this up and down movement is in the generally necessary because the feed hopper in the operating position is too large for driving on public roads Height has. Moving up and down can be achieved in a particularly simple manner by using the shredding machine or with the frame receiving the pre-screening device, slideways running from the front bottom to the rear top with which the feed hopper is moved upwards when the shredder is in the operating position is moved, and vice versa. It is also possible to pivot the feed hopper, which makes it particularly easy Way by rolling provided at the discharge end of the feed hopper rollers on a slideway of the feed hopper or whose discharge end can be moved up and down.

The effect achieved by the invention described above can also be achieved if the wheelset is kinetic reversed and the delivery device on the chassis in its longitudinal direction between an operating position in which the delivery device is located under the shredding machine and a driving position in which the wheel set is under the shredding machine is located, can be moved back and forth.

However, this training requires a special version of the chassis, but should also fall under the patent.

In the drawing, an embodiment of a mobile shredding plant according to the invention is shown, namely demonstrate

Fig. 1 shows the system in operating position A and Fig. 2 shows the system in driving position B.

The shredding plant is arranged on a semi-trailer truck chassis 1 which is provided with a three-axle wheel set 2 at the rear end. The articulated lorry is denoted by 3. Seen from the front to the rear there is a feed hopper 4 with _{apron conveyor 5 f} a preliminary sieve device 6 with feed chute 7, frame 8 and collecting funnel 9 for material to be discarded and collecting funnel 10 for fine grain, a crushing machine (impact mill) 11 with underneath arranged dispensing device 12 and a drive motor 13 for the shredding machine. The pre-screening device, the shredding machine and the drive motor are arranged on a common frame 14 which is movable in the longitudinal direction on the chassis 1 and which can be moved by means of two hydraulic cylinder-piston units 15 which are supported against a support bearing 16 provided at the end of the chassis.

The feed hopper 4 is mounted so that it can be swiveled up and down about an axis 17. He is resting with the one facing the shredding machine End over rollers 18 on a sliding track 19 running from the front bottom to the rear top, which is attached to the frame 8 of the pre-screening device 6 is attached. When the shredding machine is moved into the operating position, the feed hopper 4 pushed up by means of the slide 19 and the rollers 18. The uppermost parts 20 of the hopper side walls are known in FIG V / e can be folded down so that they do not exceed the permissible height in the driving position.
