BRIEF SUMMARY
FIELD OF THE INVENTION
The invention relates to a vehicle for receiving and transporting waste materials, having a collection container which is detachably disposed on the vehicle, behind the cab, and has a filling opening at its end on the side of the cab, the vehicle further having a device for receiving at least one refuse container, which device empties the received refuse container into a discharge hopper disposed behind the cab and cooperating with a press, the output opening of which hopper is associated with the filling opening of the collection container disposed in the lower region of the end wall.
BACKGROUND OF THE INVENTION
A vehicle of the above type is shown and described in WO/93/15981. In a preferred embodiment of this vehicle, the collection container can be detachably connected to the vehicle, so that an empty container can be received by the vehicle and the filled container can be removed from the vehicle and transported by a vehicle serving strictly as a means of transport to a dumping site or other unloading site. The collection container in this instance can be provided with support legs, as known from, for example, so-called interchangeable superstructures, so that the supported collection container can be received by the vehicle in that the vehicle travels backwards under the collection container and, after corresponding positioning, the collection container is connected to the vehicle. The vehicle can also be provided with a so-called hook lifting device, so that the collection container, which is provided on its end wall with a corresponding receiving eyelet, can be pulled onto the vehicle frame by the gate-shaped lifting arm which is pivotable in the longitudinal direction of the vehicle, and removed from it again in a corresponding, reversed movement.
A significant problem of removable collection containers of this type lies in closing and detaching the container after filling without allowing residual refuse to fall onto the vehicle or the surrounding area.
in the known vehicle, the problem was solved in that the output opening of the discharge hopper has a tubular extension that projects into the collection container through the filling opening disposed in the lower region of the end wall of the collection container, with sealing means being provided which seal the tubular extension against the filling opening. Thus, during the filling process a perfect seal is achieved for the transition point between the press and container. Because the refuse pressed into the collection container "springs back" to a considerable extent when the pressing pressure is removed, the significant problem exists of detaching the filled collection container from the vehicle without allowing refuse to fall out of the filling opening. In the known vehicle, this problem was solved by a known tubular extension which extends into the collection container, with the filling opening being able to be at least partially closed by a blocking plate which can pivot into the interior of the container when, during detachment of the container, the container is pulled far enough away from the tubular extension that the closing door can be lowered.
SUMMARY OF THE INVENTION
The object of the invention is to improve this region of a collection vehicle of this type, both with respect to function and construction, in order to achieve a perfect seal during filling and a clean seal during detachment of the collection container.
In accordance with the invention, this object is accomplished by providing a vehicle for receiving and transporting refuse materials which comprises: a vehicle frame; a cab disposed on the vehicle frame; and a collection container detachably connected to and disposed on the vehicle frame behind the cab. The collection container includes: a front end wall at an end thereof closest to the cab, the front end wall defining a filling opening therein at a lower region thereof, the filling opening being bounded by a frame; and a door disposed at the front end wall and being movable for opening and c
