Definitions
- the invention relates to a truck mixer with one on one Vehicle frame rotatably mounted and provided with a rotary drive Mixing drum, one with one at its rear end has a circular edge, with a frame-fixed held outlet funnel, the bottom of the opening covered, and with one at its upper edge on a frame-fixed Bracket or holding part pivoted, round, the opening closing lid through which a funnel passes and the one opposite the edge of the opening by a turn the mixing drum seal is sealed and the by an articulated with this and a frame-fixed part Pressure medium-piston-cylinder unit between its closed position and its open position is pivotable.
- a truck mixer of this type is known for example from EP 0 374 682 B1 known.
- Truck mixers are increasingly used to transport liquid Mixed material used so that it is necessary to open the rear opening seal the drum with a lid that spills out of the mixed liquid prevented.
- a known common lid system of the type mentioned is explained in more detail below with reference to FIGS. 5 to 7 of the drawing:
- the mixing drum 2 has on her rear end of a circular opening 3 with a conical shape circumferential flange-like edge that widens outwards 4.
- the lower part of the flange-shaped edge 4 is from one outlet funnel 5 held in a frame-fixed manner.
- This discharge funnel 5 consists of two essentially U-shaped, groove-shaped parts arranged at an obtuse angle to each other 6, 7, whose lower legs in corresponding cutouts overlap the flange-shaped edge 4 of the mixing drum 2.
- the two channel-shaped parts 6, 7 of the discharge funnel are in Area of the vertical center plane of the mixing drum 2 in the manner welded together that they form an outlet opening 8.
- the outlet funnel 5 is by lateral holding pieces 9, 10 and intermediate trestles or supports, not shown connected to the vehicle frame.
- a circular closure by a joint 15 via a support piece 16 17 is articulated.
- a pressure medium piston-cylinder unit 19 is provided, whose cylinders are centered on a triangular plate 20 is articulated, that with the outer legs of the side parts 6, 7 of the discharge funnel is welded, and its piston rod hinged to the central upper region of the hopper 18 is.
- the cover 17 is shown in its closed position, in which the cover seal grinds on the flange-shaped edge 4 of the Mixing drum is applied.
- the lid system and the seal and mixing drum rim is a good and easy access desired to the opening area of the mixing drum, but that in the known Truck mixer is hindered that the opening angle a 1 of the cover severely restricted by hitting the outer wall of the discharge funnel is.
- the invention is therefore based on the object of an improved truck mixer of the type mentioned to create a safe pouring of the mix allowed and at the same time easy access to the opening of the Mixing drum enabled for maintenance and cleaning purposes.
- the outlet funnel is therefore with one of the contours of the lower region of the lid edge appropriate round cutout provided that the pivoting of the Lid allowed beyond the outlet funnel.
- the mixer is not the opening angle of the lid through the outer wall of the discharge funnel because the lid is pivoted beyond this can be. Will the pressure-piston-cylinder unit pivoting the cover loosened or unhooked, it can even be moved down to the mixing drum fold back so that the opening of the mixing drum is fully released.
- the curvature of the cutout of the discharge funnel is expedient so adapted to the curvature of the lid that the When pivoting, cover the edge of the cutout straight can happen.
- This configuration therefore provides that between approximately in the area of the outer wall of the discharge funnel pivoted lid and the neckline just a narrow one Gap remains so that the lid is emptied during the emptying process closes the outlet funnel to the outside and an undesirable Mix material escapes over the edge of the discharge funnel prevented.
- An almost complete conclusion is reached if there is a corresponding partial discharge swung out lid in the plane of the outer wall of the Outlet funnel.
- the lid is expediently mounted on a bracket, the Leg connected to the outer side parts of the discharge funnel are.
- Two side pressure medium piston-cylinder units can be used to pivot the cover be provided. These pressure medium piston-cylinder units are appropriately articulated with the side parts of the discharge funnel and the filling funnel connected.
- the lid system according to the invention differs according to FIGS. 1 to 4 differs from the known ones according to FIGS. 5 to 7, that the upper edge 30 of the outer wall of the discharge funnel 5th is provided with an arcuate curved cutout, the Contour essentially through the respective edge area of the cover 17 is determined, the plane of the outer wall of funnel 5 penetrates.
- the bottom of the edge of the Cover 17 is on the contour of the upper edge 30 of the outer Wall of the discharge funnel 5 matched such that between the narrowest possible gap remains in the two edges, the on the one hand an unimpeded pivoting out of the cover 17 allows the discharge funnel 5 and on the other hand undesired leakage of mixed material after swiveling the Lid 17 prevented in the emptying position.
- the cover 17 For pivoting the cover 17 are pressure-piston-cylinder units 31, 32 provided, the cylinders on holding pieces 33 are articulated with the upper side regions of the Discharge funnel 5 are connected.
- the piston rods of the pressure medium-piston-cylinder units 31, 32 are bow-shaped Holding pieces 34 hinged, the legs of which with the side walls of the inlet funnel 18 are welded.
- the swiveling of the cover 17 serving pressure medium piston-cylinder units 31, 32 are laterally outside in the manner shown in FIG. 4 the pivoting range of the lid 17 is arranged so that the Cover 17 free of obstacles also via the pressure medium piston-cylinder units 31, 32 can swing out.
- the lid system according to the invention is in one position can be seen in which the lid 17 the opening of the mixing drum 2 closes.
- the cover is 17th swung into its emptying position by an angle ⁇ 1, in which is the lower edge area of the cover 17 in the area of Edge 30 of the cutout of the outer wall of the discharge funnel 5 is located.
