3. The shredding/cutting machine according to claim 1, wherein at least two inclined deflecting elements are arranged opposite one another in each conduit and laterally of each tool.

4. The shredding/cutting machine according to claim 1, wherein a further partition wall is arranged in each conduit and arranged centrally between the side walls.

5. The shredding/cutting machine according to claim 4, wherein the further partition wall forms the side wall of another conduit.

6. The shredding/cutting machine according to claim 1, wherein the tools arranged in the conduits are each in a tool holder seat and that the inclined deflecting elements each rest on a respective tool at least on its upper part or on the tool holder seat or overlays the tool holder seat.

7. The shredding/cutting machine according to claim 1, wherein the additional deflection elements are detachably connected to the frame.

8. The shredding/cutting machine according to claim 7, wherein the additional deflection elements have at least one cutting edge.

DETAILED DESCRIPTION OF THE INVENTION

(8) In FIG. 5, the reference numeral 200 denotes a machine for shredding and cutting biomass and the like. The reference numeral 201 denotes a frame in which a tool holder rotor 100 is rotatably mounted. The tool holder rotor 100 is driven, for example, by a transmission belt (not shown), which can be driven by means of a hydraulic motor or the like, or by means of a shaft driven by the vehicle carrying the shredding machine. A series of walls 104 are disposed on the tool holder rotor 100. These walls 104 form conduits 105 in which the tools 103 for cutting the biomass are supported by tool holders. When the tool holder rotor 100 rotates, the biomass enters the conduits 105. A deflecting element. 102 is arranged in front of the tools 103. This deflecting element is preferably inclined towards the tool 103. In this way, the deflecting element 102 deflects the biomass in the direction of the cutting tool 103. The deflecting element 102 covers at least 60% of the width between the walls 104 that form the conduits 105. The deflecting element 102 advantageously covers the entire width between the walls 104.

(9) The tool 103 is received in a tool holder seat 103a. The deflecting element 102 advantageously overlays at least a part of the tool holder seat 103a.

(10) The deflecting element 102 advantageously adjoins the tool 103 and/or the tool holder seat 103a, at least in its upper part.

(11) The deflecting element 102 may also consist of several parts, but consists advantageously of a single sheet.

(12) a further wall/partition 101 is advantageously arranged in the conduit 105 formed by the walls 104, which is advantageously arranged centrally between the walls 104 and extends along the circumference of the tool holder rotor 100.

(13) This partition wall 101 can form a side wall for a subsequent conduit 105 in which a further cutting tool 103 is arranged.

(14) A plurality of cutting tools 103 can be arranged in the same conduit 105 which formed by the walls 104.

(15) Further deflection elements 202 can advantageously be arranged on the frame 201. These deflection elements are advantageously arranged opposite the conduits 105 formed by the walls 104 on the frame. At least two further deflection elements are advantageously provided per conduit 105 and are arranged laterally to the cutting tools 103. In this way, these further deflection elements 202 deflect the biomass flowing in the conduits in the direction of the cutting tools 103, which are deflected by the deflection element 102 to the outside of the rotor n the direction of the frame 201. In order to avoid that this material is not cut or shredded, the deflection elements deflect the material in the conduits 105 and thus enable a fine and even shredding.

(16) In a preferred embodiment, the further deflecting element 202 is connected to the frame of the machine 201 by means of a detachable connection.

(17) Furthermore, the further deflecting element 202 may have a cutting element 202a in order not only to deflect and/or block the flow of material, but also to shred and/or cut the material.

(18) Finally, it is clear that additions, changes or variants that are obvious to a person skilled in the art can be made on the machine 200 described Up to now without departing from the scope of protection defined by the appended claims.
