Splashguard device for a wheeled vehicle and assembly comprising such a device

A heatable mixer (1) for the treatment of composite products based on thermoplastic material(s), in particular factory or site waste containing mostly bituminous membranes, said mixer (1) having an elongate composition defining a longitudinal treatment path between at least one inlet (2) and at least one outlet (2′), and comprising a trough (3) which is heated, and in which there is fitted at least one screw (4, 4′), and preferably two twin screws (4 and 4′) which are parallel and interpenetrate at their threads (4″), forming a unit/units for treatment by dimensional reduction and heating, and displacement towards said outlet(s) (2′) for the products to be treated introduced at the (2) or each (2) inlet, said or each screw (4, 4″) comprising a support shaft (5) which is heated, and rotated around its axis, the or each shaft (5) being positioned in the trough (3) by being arranged in the direction of the path (DT), and the products being displaced during the treatment from the inlet(s) (2) as far as the outlet(s) (2′) under the action of the screw(s) (4, 4′), and said mixer (1) comprising, at the or each outlet (2′), a unit (20) to control the flow of liquid or semi-liquid output of products treated, flowing through the associated outlet (2′),

• heating mixer (1) characterized in that the support shaft (5) is provided with blades (9, 9′ forming the thread (4″) of the screw (4, 4′) concerned, in that the opening of the or each outlet (2′) is formed directly in the wall (3′) of the trough (3), in that the or each unit (20) to control the flow of output consists of a flap valve or pivoting valve, and in that said flap valve or pivoting valve consists of a portion (3″) of the wall (3′) of the trough (3) which is swept by blades (9, 9′), this portion (3″) being able to be displaced, preferably continuously, between i) a closure position in which it closes the outlet (2′) concerned, and is incorporated in said wall (3′) as a component part thereof, preferably with continuous surface connection with the inner face of this wall, and ii) a maximal opening position in which the corresponding outlet (2′) is substantially totally open.
