Definitions

• Vehicles for receiving and transporting pourable solids, in particular waste materials, with a collecting container arranged on the vehicle behind the driver's cab are known for example from US-A-3 140 787 or US-A-3 202 305.
• these vehicles which are also known as overhead loaders
• a filled individual container located in front of the vehicle is picked up with the aid of a swivel arm arrangement which is articulated on the collecting container, pivoted over the driver's cab and emptied into an upwardly open filling opening which 5 is arranged in the region of the end of the collecting container facing the driver's cab.
• a pressure plate is slidably guided inside the collecting container.
• the disadvantage of the previously known vehicles is that the collecting container either remains firmly connected to the vehicle and the contents have to be pushed out completely by the press plate for emptying via a flap arranged at the end of the vehicle on the collecting container.
• This 5 requires a long and very expensive telescopic cylinder, by means of which the available space volume is further reduced.
• the pressure medium supply for the usually hydraulic swivel drive and the press cylinder 0 for the press plate do not cause any problems, since the corresponding pressure lines can be permanently installed here (US Pat. No. 3,140,787).
• a vehicle is also known in which the swivel arm arrangement and the pressing device are arranged fixedly on the vehicle, while the associated detachable collecting container is provided with an opening at the front which is in operation during the opening of the pressing device connected is.
• This system has the advantage that all the preferably hydraulically actuated actuating elements, such as swivel arm arrangement and pressing device, are firmly connected to the vehicle, while the collecting container is designed as a closed sheet metal container except for the front-side filling opening provided with a door is.
• the disadvantage is that special collection containers must be used for this system, which are relatively expensive in terms of sealing and closing the filler opening.
• the invention has for its object to provide a vehicle of the above type with a receivable and removable collection container, which on the one hand has a compact structure and on the other hand allows the use of simply designed collection containers.
• a vehicle with a receptacle which can be taken down and deposited for pourable solids, in particular waste materials, which is arranged behind the driver's cab and at least at least in the area of its end facing the cab, an upwardly open filling opening and one in its
• a vehicle designed in this way has the advantage that, on the one hand, the preferably hydraulically designed actuating means and swivel arm arrangement and the locking means and the push cylinder are connected to the
• the collecting container itself is formed by an at least partially open sheet metal container which can be used not only on the vehicle according to the invention but also on others
• the press plate can either be formed directly by the front wall of the container on the cab side, or an additional press plate can be arranged in the interior of the collecting container. In the latter case, a relatively small opening must be provided in the front wall through which the thrust cylinder can act on the press shield. Since the locking means for the collecting container are also arranged on the holding frame, the reaction forces between the push cylinder on the one hand and the collecting container on the other hand are taken over directly from the holding frame by the locking means when the press plate is acted upon, so that the vehicle chassis remains force-free.
• two or more push cylinders can also be provided instead of one push cylinder become.
• the piston rod of the push cylinder is articulated on the holding frame and the cylinder body forms the movable part which acts on the press plate.
• This configuration offers significant advantages for the pressure medium supply, which takes place in the area of the holding frame.
• the push cylinder is expediently releasably connected to the press plate with its movable part.
• a connecting means is provided for connecting the push cylinder to the press plate, which enables the push cylinder to be snapped against the press plate and, in the engaged state, allows the press plate to move forwards and backwards. If such an empty collecting container is picked up by the vehicle and connected to the holding frame via the locking means, then the push cylinder can also be connected to the press plate via the connecting means by advancing the push cylinder.
• the connecting means allows a free forward and backward movement of the press plate. If the collecting container is to be removed or set down from the vehicle after full filling, then the connecting means can be opened using appropriate opening means.
• the opening means can be arranged on the inner wall of the container or also on the holding frame and can be activated in each case with their own controllable actuating means, be it by hand or via pressure means.
• the actuating means are formed by simple fixed elements in the container or on the holding frame, which only engage in the connecting means for opening when the press plate has moved a little way beyond its final working position on the front container wall the container wall is pulled back by the thrust cylinder so that the opening elements can come into operative connection with the connecting means.
• the push cylinder is aligned horizontally and that holding means are arranged on the holding frame for the free end of the push cylinder. This ensures a secure fixation of the push cylinder if the vehicle is driven without a • collecting container. It is expedient here if the holding means are designed to be freely movable in a limited vertical plane. This ensures that when the pusher cylinder snaps into the snap lock of the press shield of an accommodated collecting container, deviations from the exact axis position that are not always avoidable in terms of design can be compensated for, but at the same time the pusher cylinder is held to the side to a sufficient extent in order to "break out" laterally " to avoid.
• the holding means encompass the movable end of the push cylinder in the retracted position and release it during the feed. Since there is no risk of angular deviations from the ideal cylinder longitudinal axis when the pressing plate is pushed into the collecting container are to be avoided, this measure ensures that when the pressure plate is pushed into the collecting container, the push cylinder is released transversely to its working direction and thus tilting as a result of dimensional and angular deviations is avoided.
• the thrust cylinder is arranged on the holding frame so that it can be fixed in the swung-up position. This measure makes it possible to use the vehicle for the transport of other swap bodies or other swap bodies, since when the thrust cylinder is swung up, it no longer protrudes beyond the rear vertical plane of the holding frame and thus the necessary space for handling other swap bodies is given .
• the filling opening of the collecting container has a lid arrangement with actuating means for opening and closing, which can be connected to at least one drive means arranged on the holding frame.
• the simplest version of the cover arrangement can be formed by a flap which can be pivoted towards the rear of the vehicle about an axis of rotation running transversely to the longitudinal axis of the vehicle.
• a third lid flap located at the rear edge of the filling opening is provided in the arrangement of two lid flaps which can be pivoted towards the outside, since this provides wind protection for the opened filling opening and when emptying the container over the swivel arm arrangement in the solid matter to be filled cannot be carried away by the wind.
