DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The invention concerns a cutter-mixer and bed-straw spreader wagon for cutting and mixing fibrous products such as fodder grass or straw silages for the distribution of the straw outside the wagon for making litters.
It is known that special cutter-mixer wagons which have a distribution group for tossing the straw outside the wagon are used to make litters.
In particular, the cutter-mixer and bed-straw spreader wagon which is object of the Italian Patent No. V194A000047 by the same inventor of the present patent, is able to cut and mix every product for a zootechnical use and is also used for the distribution of the straw outside the wagon for realizing litters is known.
The distribution group of the car is substantially formed of a duct which by a fan, conveys the cut straw from the screw feeders of the wagon to an adjustable delivery opening, and is connected to the end of the conduit which directs the throwing of the straw towards the zones where the litters will be realized.
In particular, the fan causes the volute to be applied laterally on one side of the wagon. Inside is arranged an impeller having blades with a curved outline that are started by a hydraulic engine. Therefore it is substantially a centrifugal fan of the known kind.
One drawback of the distribution group, is that the throwing distance which this distribution group realizes is rather limited.
The present invention intends to overcome such a limitation by having a cutter-mixer and bed-straw spreader wagon distribution group for the straw that can throw distances much greater than the cutter-mixer and bed-straw spreader wagons of the known kind.
BRIEF SUMMARY OF THE INVENTION
It is an object of the present invention that the distribution group for the straw have a delivery opening, adjustable by a rotation group started by an electrical engine. The objectives are achieved with the cutter-mixer and bedstraw spreader wagon for fibrous products that is comprised of a container having at least one inlet opening for the introduction of the material to treat; at least one rotating screw feeder arranged on the bottom of the container, having at least one couple of spirals with an opposite winding direction in order to convey the treated material in an intermediate zone of the screw feeder; at least one distribution group for conveying the treated material outside the container and comprising a delivery conduct having an end connected to a fan which sucks up the material inside the container, and the opposite end supplied of the delivery opening for directing the treated material outside the jet and the fan comprises a volute that is fixed to a side of the wagon and communicating with the inside of the wagon itself by a suction opening which is arranged in correspondence with an intermediate zone of the screw feeder. Inside the volute is an impeller formed of a circular disk keyed to motorization means suitable for starting it and having a plurality of blades, each of which presents at least a plane surface having an outline that is radially diverted towards the volute beginning from the central zone of the circular disk which is keyed to the motorization means.
According to a preferred embodiment, the impeller has four orthogonal blades and a delivery opening is connected to a delivery duct by a rotation junction that can put it into rotation so to convey the used material straw in the desired direction.
The fan allows some cut and mixed straw to be thrown out to greater distances than those known in the art.
The turning delivery opening is fixed in an end position relative to the delivery opening, it is of a contained length and lighter. It can be put in rotation by kinematic mechanisms coupled to the rotating joint which are actioned by an electric engine of low power without the help of heavy and expensive hydraulic actuators.
