Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides that at one end on the carriage or frame a crusher is arranged, optionally with a sieving device connected in front, and at the other end on the carriage or frame. , movable or transportable, in which a feeding device consisting of a feeding hopper and a belt conveyor is arranged, which can be pivoted up and down about an axis provided at the other end between a lifting operating position and a lowering running position. This relates to a crushing device.

Arrangements of this type are such that the feed device, which in the operating position projects beyond the feed opening of the crusher or beyond the feed opening of the sieving device connected in front of the crusher, is used when traveling on public roads or If the overall height of 4 m prescribed for transport is not exceeded, and if the feed end of the feed device projects beyond the pivot axis, the feed hopper may be located as low as possible in the operating position. It is designed so that it can be supported on the ground.

It is not easily possible to rotate the feeding device up and down. This is because the crusher or the sieving device connected upstream thereof locates the feeding device in the region of rotation. Various devices have therefore been provided to enable this pivoting movement.

For example, the feeding device is mounted on a link, which makes it possible to move the feeding device to a lower position in an arc around the device to be fed (US Pat. No. 3,203,632). In this case, however, the feed hopper is very high in the operating position, which is disadvantageous for feeding by the tractor shovels that are normally used.

In other known movable grinding devices, the sieving device is pivotally mounted on the grinder, so that the feeding device can be swung somewhat downwards and outwards (DE 1607502). . However, in this case the feeding device is only swung downwards slightly, which is particularly the case if: This is disadvantageous when protruding beyond the axis. The small pivot angle does not allow the feed end to be as low as possible in the operating position.

Furthermore, it is known to allow the delivery end of the belt conveyor of the feeder to be pivoted high relative to the rest of the belt conveyor, so that a downward pivoting of the feeder is possible (German Patent Publication No.
Publication No. 1816165). However, this approach complicates the construction and drive of the two-part belt conveyor.

Finally, from the magazine "Water, Air, Operation", September issue, 1982, page 81, a mobile crusher known from
Both devices are movably arranged on a carriage in such a way that the crusher and the sieving device connected in front of it are located above the wheel set with respect to the vehicle. This also provides the necessary space for the downward swivel of the feeding device into the running position. However, if the drive, transmission and auxiliary drive for the crusher are arranged on the carriage or frame, such movement of the crusher is not possible.

An object of the present invention is to provide a transportable or transportable device in which the transport of the feeding device from the operating position to the transport position and vice versa can be carried out without any problems in the above-mentioned cases and therefore in a simple manner. The aim is to create a transportable crushing device. According to the present invention, this object is achieved by taking the following measures. That is, the supply device is disposed on the carriage or frame so as to be movable in the longitudinal direction of the carriage or frame as follows. That is, the feed device is arranged in such a way that it can be freely swung downwards into a traveling position from the crusher or from the sieving device connected in front of it, when it is furthest away from the crusher.

Of course, in the case of movable grinding devices, it is already known to remove the feed device from the grinder and move it in order to bring it into a traveling position. However, for this purpose, the feeding device is arranged on a separate carriage that can be connected to the main carriage (Seisen Gijutsu, 1975, p. 395). On the other hand, it is an object of the invention to arrange all the equipment of the device on a single and not excessively long carriage or frame, thereby significantly simplifying the commissioning and shutting down of the device.

According to one embodiment of the invention, the movement of the feeding device is achieved in that the pivot axis for the feeding device is supported on a carriage or a frame which is movable in its longitudinal direction. It is done. The carriages are provided on both sides of the carriage or frame in order to ensure that the feed end of the feed device projects beyond the pivot axis, so that when the feed device is swiveled high, the feed end can be swung downwards. Recesses are arranged on the sliding tracks and between the sliding tracks, opening towards the ends of the carriage or frame. The downwardly swiveled feed end of the feeding device is moved into this recess from the carriage or frame when the highly swiveled feeding device is moved towards the crusher.

According to another embodiment of the invention, it is also possible to arrange the feeding device on a support that is supported on a pivot axis that is fixedly provided on the carriage or frame. In this case, the feed device is moved diagonally downwards on the support in a high pivoted movable position and then pivoted downwards into the traveling position.
In this embodiment, the feeding device in the highly swiveled position must not completely reach the ground in order to be able to carry out the moving movement.

The movement of the carriage on the carriage or frame, or the feeding device on the support, takes place in particular by means of a hydraulic cylinder-piston unit.

Next, both embodiments of the transportable crushing device according to the present invention described above will be described with reference to the accompanying drawings.

In both of the embodiments shown, the crushing device is mounted on a frame 1, which is equipped with support jacks 2 for resting on the ground and which can be transported by a low bed 3 of a semi-trailer (FIGS. 3 and 6).
