Definitions
- the subject of the present invention is cutters for fodder-cutting machines and a cutting machine including the cutters.
- the main technical aim of the present invention is to define a novel shape of the cutters for cutting machines and a novel distribution of the cutters which permit improved performance.
- an important object of the invention is that of providing cutters the structure and operation of which improve the quality of the shreddings and shredding capacity for a given power used.
- One of the chief objects of the invention is to provide a cutting machine in which the cutters are arranged on the rotor so as to achieve improved transportation of the material shredded.
- FIG. 2 is a partial perspective view of the rotor of Figure 1 ,
- FIG. 3 is a side elevational view of one of the cutters with which the rotor of Figure 1 is equipped.
- a rotor of a fodder-cutting machine is generally indicated 1 and includes a drum 2 from the cylindrical wall of which a plurality of plate-like supports 3 project radially.
- a respective cutter 4 is fixed on each support 3 by nut and bolt connections 3a.
- the rotor 1 has a horizontal axis X and is driven, for example, by a hydraulic motor, not shown.
- Each of the cutters 4 comprises a blade 5 having a curved, sabre-shaped cutting edge 6.
- the side of the blade remote from the cutting edge 6 is indicated as the rear edge 7.
- the cutting edge 6 of the blade 5 has a leading angle 10 at which the cutting edge and the rear edge converge, and a following portion 11.
- the cutting edge 6 is shaped so as to diverge from the curved wall 2 of the rotor when the cutter is mounted thereon, as the cutting edge 6 extends from the leading angle 10 towards the following portion 11.
- the cutting edge 6 has a spiral shape with a gradient which decreases from the leading angle 10 towards the following portion 11.
- first portion 7a On the rear edge 7, starting from the leading angle 10, there is a first portion, indicated 7a, which has a curved surface complementary with the profile of the cylindrical wall of the drum 2 so that, when the cutter is mounted on the respective support, the first portion 7a fits against the outer surface of the curved wall 2.
- the cutters 4 are distributed at regular intervals along a spiral path on the rotor 1 and, preferably, along two spiral paths so as to form two interrupted screws 12, 13 which, with reference to the cutting movement of the rotor indicated by the arrow F, tend to transport the shredded fodder towards the centre of the rotor.
- Each interrupted screw 12, 13 preferably has several spiral threads.
- the cutters 4 are offset with respect to a given generatrix of the rotor so as to improve the transportation of the shredded fodder towards the centre of the rotor.
- the sabre-like shape of the cutting edges 6 of the cutters 4 leads to their progressive penetration into the mass of fodder being shredded. This penetration progresses both with the cutting movement and with the advance of the machine towards the mass of fodder.
- the spiral distribution of the cutters on the rotor provides for rapid transportation of the shredded fodder towards the centre of the rotor so that it is collected and transferred by conventional means of the cutting machine into the mixing container of an optional mixing cart associated with the above-described unit.
- the invention thus achieves the objects proposed and offers many advantages over the prior art.
