DESCRIPTION:
BRIEF SUMMARY
CROSS REFERENCE TO RELATED APPLICATIONS
This application is a national phase of PCT/EP93/00591 filed 15 Mar. 1993 and based, in turn, on German national application P4210809.8 of 1 Apr. 1992 under the International Convention.
FIELD OF THE INVENTION
The present invention relates to a crushing machine and, more particularly, to an impact crusher, comprising at least one rotatably driven rotor mounted in a housing and equipped with crushing elements, as well as at least one impact mechanism which faces the rotor and is fitted with impact elements.
BACKGROUND OF THE INVENTION
German patents nos. DE-A 25 16 014 and DE-A 39 39 598 describe a crushing machine, in particular an impact crusher, which comprises a rotor equipped with crushing elements, wherein inside the housing at least one impact mechanism fitted with impact elements is mounted. In order to replace the impact elements, at least part of the housing can be swung around a horizontal axis. A disadvantage of such an apparatus is that it is difficult or impossible to loosen from the outside the impact elements in the area of the impact mechanisms. Moreover problems are encountered with respect to removing the impact elements from the inside of the machine. The same also applies, of course, to the subsequent re-fitting of the impact mechanisms in the reverse mode of operation.
OBJECTS OF THE INVENTION
It is the object of the invention to provide an improved crushing machine so that the impact elements can be replaced without difficulty and so as to ensure, during the replacing of the impact elements, the safety of the operator by reducing possible accident risk.
Another object is to make it possible to replace the impact elements more quickly and, therefore, more cost effectively compared to the state of the art, and in this way considerable reduce the down time of the crushing machine.
Finally, it is an object to improve the accessibility of the components in the area of the impact mechanism and to simplify the work involved in replacing the impact elements.
SUMMARY OF THE INVENTION
These objects are achieved according to the invention in that the impact mechanism or mechanisms is or are mounted in at least one frame which is independent of the housing, and which together with the impact mechanism or mechanisms can be swung into a position outside the housing.
The frame or frames can be swung about a horizontal axis, whereby the impact mechanism or mechanisms can be moved into a roughly horizontal position. The frame can be formed by lateral rocker arm parts, between which the respective impact mechanism is mounted on at least one side.
The frame can be divided into an upper rocker arm part and a lower rocker arm part, the upper part receiving the respective impact mechanism and the lower part being swingable with respect to the housing. In a retracted position the upper part of the rocker arms can dip the housing together with the respective impact mechanism, while the lower part of the rocker arms remains outside the housing.
The rocker arm parts can form at the same time at least one section of the rear wall. The rear wall can be formed by at least one removable and/or swingable flap, which can be joined to the housing.
The machine can have an upper, as well as a lower flap assigned to the respective rocker arm part whereby the upper flap is swingable and the lower flap is removable.
According to a feature of the invention, a wall section is provided between the two flaps which interconnects the two rocker arm parts. The wall section can receive at least one adjusting device for the respective impact mechanism. In the retracted position the impact mechanism at least of the upper part of the respective rocker arm can be locked in place with respect to the respective housing part, particularly by bolts.
A further section of the rear wall can be provided with impact elements facing the rotor, whereby this section can be swung into a position outside the housing, independently from the housing, or the impact mechanism mechanisms. The further
