Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) In the figures:

(2) FIG. 1 consists of FIGS. 1A, 1B and 1C showing different views of details of the disintegrating device according to the invention,

(3) FIG. 2 is an enlarged representation of the area of the base comb with counter blades and sieve elements of the disintegrating device according to the invention, and

(4) FIG. 3 consists of FIGS. 3A, 3B and 3C showing further details of the suspension of the comb elements.

DETAILED DESCRIPTION OF THE INVENTION

(5) In the following an embodiment of the disintegrating device according to the invention will be described by means of the figures. It is pointed out that the drawn representation is only an example for a disintegrating device according to the invention which has to be understood by no means as restricting. Identical features in the drawings will be provided with identical reference numbers so that all drawings will be described complexly.

(6) FIGS. 1A to 3C show side views and three-dimensional presentations of the base comb II provided with sieve elements 41 of the disintegrating device according to the invention. In FIGS. 1A and 1C the disintegrating roller 1 is shown with disintegrating tools 2 arranged thereon. The disintegrating roller 1 is arranged in a not shown frame as well as the base comb II with the elements arranged thereon that will be described later on. An arrow and reference number I schematically indicate the comb system according to the invention. It consists of a base comb II on which the counter blades 3 and the sieve elements 41 of the sieve device 4 are arranged. The base comb II can be swiveled via an axle A. The swiveling movement is executed by a swiveling device 5 formed by a hydraulic cylinder 50 attached in the device via a base comb axle 51 and a housing axle 52. The housing axle is provided here in the not shown frame of the disintegrating device. The sieve elements 41 are attached to a suspension 7, which is part of the mount, to the base comb II. The springy support is accomplished by the spring system 6 arranged, as well as the suspension 7, at a preferably replaceable holding device 8. Suspension 7 and spring system 6 are spaced parallel from each other which has the result that by means of an adjustment device 62 the preload force of the spring 61 as well as the angle of attack a of the sieve elements 41 can be changed. This is a big advantage as, for example, different material to be disintegrated can be reacted on accordingly, i. e. the angle and, if necessary, the preload force, can be set. Spring 61 is a pressure spring arranged at least partly in a spring sleeve 63. The suspension 7 of the sieve elements 41 is preferably a cardanic suspension. Of course, this is only one of several possible modifications for suspensions that is by no means limiting. The swiveling device 5 comprises another hydraulic cylinder 9, however, that acts in opposite direction of hydraulic cylinder 50. Hydraulic cylinder 9 sets the distance of the base comb II to the disintegrating roller 1 up to the stop. At the base comb II a toothed bar 31 is provided where the counter blades 3 are provided individually or as assembly with a multitude of counter blades 3. Between the toothed bar 31 and the counter blade 3 designed as comb tooth a wear plate 32 is provided that prevents the entire base comb II from being replaced when worn. Only the wear plate is replaced. The counter blades 3 are defined at the base comb by means of a locking device 10, preferably also hydraulic.

(7) The invention has been described above by means of an example. However, the invention is not restricted to it. The claims filed now and to be filed later on along with the application are attempted formulations without prejudice for obtaining broader protection.

(8) References in the sub-claims relate to the further design of the matter of the main claim through the characteristics of the respective sub-claim. These are however not to be understood as a waiver of independent subjective protection for the characteristics of the referred sub-claims.

(9) Characteristics only disclosed in the description so far may now, in the course of proceedings, be claimed as being of inventive relevance, for example to distinguish from the state of the art.
