Description

The invention relates to a device for loading a ship with loose bulk goods, in particular with Cement. Lime or gypsum, the device being arranged to be movable on rails outside the ship and the bulk material can be fed to the ship's ship via a feed belt, one of which is stationary and one that is rotatable Conveyor belt as well as on the boom has a boom belt that can be changed in its height, with each Transfer section of the bulk material from a conveyor belt to the subsequent conveyor belt, a dedusting line is connected and where the feed belt is a Dump truck is assigned, which is permanently attached to the steel structure of the ship loading device and is arranged so that it can be moved along with it on separate rails.

To load a ship with loose bulk material with a device of the type shown, the must Bulk goods are transferred several times from one belt to the other belt. The resulting dust is sucked through mostly flexible hoses in order to ensure the mobility of the loading device. Flexible hoses are extremely prone to breakage and, in addition, geometrically hardly suitable as dust ducts. BcI Flexible hoses, dust deposits cannot be avoided, which creates the risk of failure of the dedusting process consists. Special dust removal problems occur on the moving parts.

The transfer of dusty bulk goods to one vertically rotating boom is a problem even without dust removal, as the height of fall varies depending on the position of the Boom changes.

In the case of movable loading devices, the loading is of bulk goods via an open infeed belt is also problematic. When arranging a normal cover of the infeed belt to the discharge trolley, the mobility of the discharge trolley is hindered. Such Cover is therefore ruled out for the travel range of the drop trolley.

In the device known from DE-OS 27 01 343 for loading containers in general

With a thin material, the material becomes a Auinahmeirichter made by gravity over rotatable hose slides one below the Receiving funnel located container supplied. The hose slides are spaced accordingly shaped outer tubes, with the space between hose slides and outer tubes attached to a Suction member is connected to generate a negative pressure. This is intended to bring material out of all rotating connections between the hose lines be prevented.

Apart from the fact that with this known training nu: a transport of the material due to the effect of gravity is possible and therefore only one in a limited radius below the receiving funnel Loading of any container can take place, is a relatively large constructive for the functionality Effort required. A use for loading a ship with loose bulk material is due to the limited loading radius excluded.

The invention is based on the object of developing a device of the gaming $ 0 indicated at the beginning, that a dedusting at all points, -uch at the transition to the vertically rotating boom, as well as one Perfect removal of the dust is guaranteed and the feed belt also in the area of the displacement path of the drop trolley can be provided with a rainproof cover without the sliding ability of the drop trolley is restricted.

According to the invention, this object is achieved in that at the transfer points from one belt to the next Band dedusting hoods arranged as well as the connected dedusting lines through pipes are formed and that the feed belt in the displacement area of the discharge carriage by telescopic pull-out and / or sliding covers is covered. The dust collector between the conveyor belt of the rotatable part and the conveyor belt of the boom can be formed by a telescopic chute, the displaceable part of the chute expediently the conveyor belt de .; Boom and the fixed part of the chute is assigned to the rotatable conveyor belt.

In an embodiment of the invention, the dust extraction hood in two parts between the conveyor belt of the stationary part and the conveyor belt of the rotatable part designed and consists of a fixed and a rotatable part connected to it.

Further expedient refinements of the invention emerge from the further subclaims.

The design according to the invention enables reliable dedusting at all points. The arrangement of telescopically extendable and / or displaceable cover hoods in the is particularly advantageous Sliding area of the drop trolley. As a result, when the infeed conveyor is covered, the discharge trolley is in his Movements not inhibited.

When obtaining the required vertical movement of the boom, the arrangement of a dust extraction hood in the form of a closed chute, perfect dust removal in every position of the boom guaranteed. By using pipes to form the dedusting lines and their rotatable ones Connection Is the risk of dust deposits and a possible failure of the dedusting system locked out.
