This invention relates to a bulk leveling or unloading device in a loading or storage space, comprising at least one scraper device arranged to transfer bulk to a second scraper device, which in turn is adapted to transfer the received bulk to at least one unloading device. movable transversely to the direction in which it moves the bulk.

A device of the above type is disclosed, for example, in French Patent Nos. 1,343,751 and 911,594. When using this type of device, for example when unloading a ship's cargo, it may be necessary to move bulk up an inclined plane to one or more belt conveyors transverse, the bulk material. Belt conveyors require a lot of space and thus reduce the effective volume of the cargo hold. In addition, the placement of belt conveyors on the bottom of the vessel makes it difficult to carry out repairs and maintenance.

When the machine is used on ships, especially large ships, arches, stiffening plates and plates often protrude into the cargo hold, 2 661 56 which prevents scrapers from removing loose goods accumulated near the outer walls of the hold. In addition, scraper devices may have difficulty extending the full width of the hold if its width varies in height, because the guide bars of the scraper devices depend on vertical guides.

The object of the present invention is to provide a leveling and unloading device of the above-mentioned type, by means of which some of the above-mentioned problems can be eliminated.

This is achieved by the invention as defined in the claims.

To clarify the invention, it is described with the aid of structural examples shown in the drawing.

Fig. 1 shows a section of a ship's hold containing a leveling and unloading device according to the invention without a belt conveyor requiring space in the lower part of the hold, Fig. 2 shows a cross section of a ship's cargo space varying in height and in which the device according to the invention is placed; Fig. 4 shows a section of the device according to the invention shown in Fig. 1, and Fig. 5 shows the device according to Fig. 4 in the direction of the arrows VV.

Figure 1 shows a cross-section of a ship's hull 1 with a cargo hold 2 on which a scraper device 3 is mounted. The scraper device can move bulk goods in the longitudinal direction of the ship, i. perpendicular to the plane of the drawing, and can be moved transversely along the guide beams 4, which in turn can be moved vertically along the guides at their ends. In addition, a scraper device 5 of the same type is mounted at the other end of the scraper device 3, which forms an angle with the scraper device 3 and is thus transverse to this. The transverse scraper device 5 can move the bulk material towards the vertical conveying device 6, which is, for example, placed close to one side of the hold. In the illustrated construction example, the vertical conveying device 6 is a Paternoster conveyor which conveys bulk goods to a belt conveyor 7 on the deck of the vessel. The transverse scraper device 5 can be two or more parts, 3 661 56 of which the parts transport bulk in their own or the same vertical conveyor. The transverse scraper device can be moved vertically, for example by means of suspension members 8, the length of which can be changed. The transverse scraper device is preferably always kept somewhat lower than the main scraper device 3 in order to obtain a certain avalanche angle by means of the latter. In this case, the bulk falls by itself and the power consumption can be adjusted.

By using a transverse scraper device in conjunction with a vertical conveyor, the hold can be filled more efficiently by avoiding dead spaces below the oblique levels leading to the transverse belt conveyors. In addition, repairs and maintenance are facilitated because the scraper devices can always be located above the load.

Figure 2 shows how the scraper device according to the invention is mounted in a hold 2, the width of which varies greatly in the height direction. The scraper device 3, the guide bar of which is indicated in its entirety by the number 4, is shown in full lines in the upper position and in broken lines in the lower position. The lower position best shows how the guide beam 4 comprises two end portions 4 'telescopically mounted in the central portion 4 ". The outer ends of the guide beam end portions 4' are provided with rollers 9 or the like moving in guides approximately parallel to the sidewalls of the hold. than the shortest distance between the controls 10. The center part 4 "of the guide bar can possibly be slidably mounted on the two end parts 4 'so that together with the scraper device 3 it can be moved all the way to the guide devices 10 when the guide bar is in its lower position. This avoids possible problems when the scraper device 3 has to be moved or the opposite.

Figure 3 shows a longitudinal section of the hold 2. It is mounted on a main scraper device 3 which moves bulk goods in the longitudinal direction of the hold, as well as a transverse scraper device 5 and a vertical conveyor 6. The main scraper device 3 is here provided By means of the digging arm 11, the bulk material can be excavated between the arches 12 and the stiffening plates 13 so that the main scraper device 3, respectively, the transverse scraper device 5 can transfer it further to the vertical conveyor. Because the excavator unit can be moved along the scraper device, it can reach any debris left between or on the protrusions and therefore the vessel can be permanently dismantled without additional equipment.

Figure 4 shows in more detail a particularly preferred embodiment of the vertical conveyor 6. It comprises a Pater-noster conveyor, the hoists 14 of which are attached to two endless chains 15 which pass over the upper and lower traction / swivel wheels 16, only the lower of which is shown.

That part of the Pater-noster conveyor which is in each case below the surface of the surrounding bulk material is protected by plates 17 which are fastened to chains which pass below the swivel wheel 19 at the bottom. The plates 17 and the chains 18 together form a blind-like device, the upper edge 20 of which, as best seen in Figure 5, can be pulled down to expose the Pater-noster device as the level of the bulk material decreases. The upper edge of the blind 20 is always held slightly below the transverse scraper device 5 so that the bulk can roll down from its end to the lifts 14 of the Pater-noster device.

The expression "vertical conveyor" used in the foregoing and in the claims is not limited to conveyors which are in a completely vertical hold, but means any suitable conveyor by which bulk goods can be moved from a lower level to a higher one.

In addition, if necessary, several vertical conveyors can be used in the same hold.
