Abstract: A truck for shredding and mixing products for zootechnical use, comprising, on a self-propelled or towed wheeled chassis, a frustum-shaped container that tapers downwardly, is open at the top, and contains a scroll that rotates with a vertical axis and has an external profile that lies on a substantially conical ideal surface, shredding cutters being fitted at the profile. Countercutters, shaped substantially like a circular sector, are pivoted in a vertical arrangement, by means of their respective vertices, to the wall of the container in substantially radial positions and can be inserted and extracted through specifically provided slots. The truck furthermore comprises an automatic actuation and control device for the positioning of the countercutters according to work variables. The actuation and control device is constituted by an electronic control unit that controls a hydraulic section for the movement of the countercutters.

Abstract: A truck for shredding and mixing products for zootechnical use, including: a self-propelled or towed wheeled chassis; a container supported on the chassis and substantially shaped like an inverted frustum, with an open top; a rotating scroll in the container that has a vertical axis and an external profile that lies on an ideal substantially conical surface; shredding cutters fitted at the profile of the scroll; and vertically arranged countercutters, shaped substantially like a circular sector, and having respective vertices pivoted to the wall of the container in substantially radial positions and extractably inserted through appropriate slots of the container. The countercutters are arranged so that the pivoted vertex of each one is in a substantially median region of the wall of the container and so that each countercutter extends downward from its pivoted vertex so as to effect the lower part of the wall of the container.

Abstract: A transmission is disclosed for trucks of the type having a wheeled chassis that is towed or independently powered and supports a substantially inverted frustum-shaped container which is upwardly open and contains a scroll with a vertical axis for shredding and mixing fibrous products. The transmission comprises a tracked-type epicyclic reduction unit which is mounted on the bottom of the container and supports the scroll in a cantilevered manner. The reduction unit is coupled to a hydraulic motor connected to a pump, which is in turn coupled to a drive unit.

Abstract: Silage extractor and conveyor arm including an elongated box-like structure which contains means for conveying the material extracted from the silo. A first end of the structure is provided with a mill for cutting and removing loose or ensiled material, and a second end of the structure is articulated, about a horizontal axis, to a vertically extending support which is mounted on a supporting frame. The arm is characterized in that the support to which it is articulated is rotatably coupled to the supporting frame about a vertical axis.

Abstract: The machine for preparing litters for animals in the field of zootechny includes, on a self-propelled or towed wheeled chassis, a container which is provided with a scroll-like element for shredding and mixing fibrous products, for example straw and/or hay and/or equivalent products, and bladed rotating elements, suitable for spreading the fibrous products arriving from a discharge opening of the container, are associated with the machine.

Abstract: Counterblade extracting device for extracting counterblades pivoted in slots of a wall including a disk element which is rigidly associated with a lever-like actuation element and which is arranged adjacent to the side of the counterblade and rotatably coupled thereto outside the wall.

Abstract: The discharge outlet is for use with fibrous product mixers of the type which comprise, in a lower region of a lateral wall of a mixing container, a wide opening or discharge outlet at which a movable closure panel is associated. The panel is shaped substantially complementarily to the opening. The discharge outlet has a metal plate flap welded longitudinally to the lower region defined by the base of the container.

Abstract: The invention relates to a fibrous product mixing truck having a mixing container (2) with one or more vertical scrolls welded onto corresponding rotating shafts. The container is mounted on a wheeled frame through the interposition of weighing cells (3). A frame (10) of metallic tubes with a substantially quadrangular shape is welded to the container for movably supporting an unloading belt (11) facing an unloading door (7) of the container and movable from a position which is substantially internal to the truck to a position which considerably protrudes therefrom. The frame is rigidly associated with a ladder (14) upwardly connected to an inspection platform (15) and is separated from the container.

Abstract: The apparatus comprises a container mounted on a chassis having wheels and a supporting structure. A powered vertical auger is provided inside the container for mixing animal fodder therein. A side wall of the container is provided with an opening which can be selectively closed by a door. A conveyor belt having side walls and a lower chute is located adjacent the opening in the container, for transporting fodder therefrom upon opening the door. Permanent magnets are fixed to the side walls and lower chute of the conveyor and to a tubular element of the supporting structure arranged above the conveyor for removing and retaining any ferromagnetic material contained in the animal fodder being conveyed.

Abstract: A drawing and conveying arm includes a box-like duct which is internally provided with a conveyor belt and has, at one end, a wide drawing inlet in which a mill for drawing and cutting material is located. The opposite end of the arm is articulated to a container for the drawn material and/or to a supporting framework. The improved drawing and conveying arm also includes a second counter-rotating mill which is provided in the drawing inlet in a position which is parallel and proximate to the first mill. Both mills can conveniently be removed to load for example farinaceous products.

Abstract: The present invention relates to an improved mixer trailer for fibrous products which can be particularly but not exclusively used in the zootechnical field. The trailer is of the type which comprises a wheeled chassis on which a mixing container is mounted; the container is substantially in the shape of an inverted conical frustum and is internally provided with one or more vertical scrolls welded to a rotating shaft which is rigidly associated with the container. The improvements consist of the fact that the wheels are arranged in close pairs which are coupled to a same axis of rotation and are articulated to the chassis on an axis which is orthogonal to the axis of rotation. A loading device with grippers is associated with the container, and a system for drying the product contained therein is associable therewith. At the end of operation, auxiliary actuation means adapted to impart to each of the one or more scrolls a high-speed rotary motion can be connected to each of these one or more scrolls.

Abstract: The mixer is of the kind composed of a container which is internally provided with one or more vertical screws welded to a shaft which rotates about end pins fixed to the container. The improvements consist in a scraping element which is fixed to one of the pins and extends longitudinally flanking the shaft. Each scraping element has a blade which is rigidly associated therewith and scrapes the surface of the shaft and blade which is spaced from the surface.
