Description

DETAILED DESCRIPTION OF THE INVENTION The invention comprises a loading arm which is reciprocated in a pendulum-like manner over a loading shovel about a pivot axis and which is driven in each case by a reciprocating transmission mechanism. The shovel is provided with an end face that stands up at a steep slope and a back surface that is gently sloped with respect to the belt travel surface, and in this case, the reciprocating transmission mechanism is provided below the covering part of the loading shovel. and a loading shovel is articulated via a swing lever to a rocking shaft that is rotatably and firmly installed, especially in an excavator or excavator, etc., for loading waste onto a loading conveyor. Regarding equipment.

From German Published Patent Application No. 2550051, a loading device is known which consists of a loading device which is reciprocated in a pendulum-like manner over a loading shovel about a respective fixed oscillating axis. If the loading arm to be loaded has an almost triangular cross-section and is pressed into the slot with its wedge-shaped back surface running at an acute angle when performing an empty loading stroke, it will stand up at its steep slope when performing a loading stroke in the opposite direction. It is provided so that the pickpocket is pushed into the loading conveyor by the end face and the carrying surface.

The reciprocating transmission mechanism driving the loading arm and the swing lever connecting this reciprocating transmission mechanism with the loading arm are in this case free above the tilting loading shovel. They therefore interfere with the loading process and are highly exposed to dirt and damage from external influences.

A loading device of the same type is known from German Publication No. 2645596, but this loading device includes a swinging lever and a reciprocating transmission mechanism, which are rotatably provided on the swinging shaft of the loading arm. is located in a protected manner below the covering of the loading shovel, which in this case is designed in the form of a surface. In this arrangement, assembly and disassembly of the drive and transmission mechanism parts provided below the loading shovel poses a significant problem.

Starting from a loading device with a reciprocating transmission mechanism which is provided in a covered manner, the problem underlying the invention is to provide this loading device with the possibility of assembling and disassembling the loading arm beside its drive part and transmission mechanism. Even if there is, it should be formed in such a way that it can be done extremely easily.

This problem is solved by the invention in a loading device of the type mentioned at the outset as follows. This means that the oscillating shafts with their bearings are supported in an internal structure casing which can be inserted into the intake of the loading shovel and which is fixed in an easily removable manner inside this intake; The problem is solved by removably providing a rotary rigidity on the end of the internal structure of the rocking shaft protruding from the casing.

In this case, it is advantageous if the internal structure housing is provided with a side opening through which a rocking lever, which is rotationally rigidly connected to the rocking shaft inside the internal structure housing, passes through. In this case, the intake of the loading shovel is
A structural set consisting of an internal structure casing, a rocking shaft supported therein and a rocking lever is formed in such a way that it can be introduced into the intake from above and lifted upwardly from the intake. ing.

In this embodiment of the loading device, the reciprocating transmission is located next to the pivot axis in a tilted loading tray protected from damage and dirt. The pivot shaft is therefore protected in the internal housing and is mounted in a pivot bearing. At the same time, the arrangement is performed as follows.

This arrangement means that the internal housing, together with the oscillating shaft mounted in its interior and preferably the oscillating lever, each form a structural assembly, which assembly is connected to the link connection of the reciprocating drive to which it belongs. This is done in such a way that, after being disassembled, it can be easily removed as a structural unit from the intake of the loading shovel and brought into the factory for repairs. This structural set can be easily and quickly added to a loading shovel and can likewise be easily removed from the loading shovel, without the need for disassembling the structural set into its individual structural units.

In another embodiment of the invention, the loading shovel has an assembly opening for assembling and disassembling the reciprocating transmission mechanism, which is constructed in a wear-resistant manner by a cover plate or the like in the cover plate above the reciprocating transmission mechanism. It is equipped with This assembly opening advantageously merges into the associated inlet for the internal structure housing. These assembly openings are advantageously dimensioned to be larger than the dimensions of the reciprocating transmission in the pushed-in state. These assembly openings thus allow a simple and quick insertion of the reciprocating transmission into the loading shovel, and it is also possible in this case to form a link connection of the reciprocating transmission through these assembly openings. Disassembly of the reciprocating transmission mechanism is also easily possible.

The loading arm is easily releasably connected to a pivot shaft which is supported in the internal structure casing. Therefore,
The loading arm can be easily removed from the assembly before disassembly, and after assembly it can be easily connected to the end of the swing shaft which projects from the cladding of the loading shovel. Advantageously, the pivot shaft carries an external toothing at its upper end projecting from the internal housing, with which the associated loading arm meshes with the internal toothing. In this case, a retaining element in the form of a releasable, preferably releasably connected retaining plate or the like is provided, which ensures a rotationally rigid connection between the pivot shaft and the associated loading arm. It is being In the same manner, it is advantageous if the rocker lever is rotationally rigidly connected to the rocker shaft via teeth.

If the above structure set is separated from the loading excavator, the oscillating shaft can be easily pulled out of the internal structure casing, in which case the oscillating shaft can be removed with its external teeth from the internal teeth of the oscillating lever. drawn out. In this way, it is possible to easily assemble the transmission mechanism parts with the internal body housing and, correspondingly, to dismantle this transmission mechanism from the internal body housing. In order to hold the above-mentioned structural assembly in the loading shovel, it is advantageous for the internal structure to have an assembly flange, at which the structural assembly casing can be fixed by screws to the cover plate of the loading excavator. It is possible. Advantageously, the loading tray itself consists of a □-sided shaped body. The loading shovel is provided with an inlet in both the upper cover plate and the base plate below, each adapted to the contour of the internal structure casing, in which the inner structure casing is formed integrally. Advantageously, they fit together. K between the open end side of the internal structure casing and the lower side of the associated loading arm
It is advantageous to have a harakin. For this purpose, metal packing, labyrinth packing, etc. are used. Advantageously, the inner structure casing is closed on its underside with a releasable cover. Advantageously, the rocker levers are each mounted between one bearing in the internal housing. In this case, it is advantageous for the upper bearing to have a larger diameter than the lower bearing, so that it is possible to extract the stepped rocking shaft upwardly from the internal structure casing. be.

Furthermore, the invention relates to an embodiment of the loading device in which the reciprocating transmission mechanism is arranged inside the hollow loading arm. In this loading device, the loading arm is articulated, on the one hand, in a link part to a rotary, rigid rocking lever, which is also located inside the loading arm, and on the other hand, in an internal link part, to the loading arm itself. There is. In this case, the swing levers can be swung around the shaft bolts to which they are each fixed, and the shaft bolts can be inserted into the bolt holes in which the internal teeth of the loading shovel are formed, and in this case Advantageously, a retaining element is provided which retains the shaft bolt in the bolt hole. Advantageously, the loading arm is provided with an assembly opening that can be opened and closed by a cover.
