Description

UNLOADING MACHINE This invention relates to unloading machines for unloading heavy ore material like coal, cement, iron ore transported by a flat car or rail freight car from a mine or port.

There is known in the prior art, a forklifter or a forkmachine for rotating a freight car (a so called 'rotating dump').

This must be operated by manually, and is expensive to equip. In addition, the prior art forklifter can only be used with a freight car of limited size, thus, it cannot cope with various sizes of freight cars and thus kinds of cargo material. Especially in winter, when the cargo is frozen, it takes too much labour to unload, and other trailers are needed to meet the freight car with the fixed machine.

I have appreciated that the prior art is deficient.

Accordingly, the invention generally resides in providing an unloading machine to cope with the above mentioned problems, and which can trail freight cars without any aid of another trailing car. The invention also generally resides in providing an unloading machine that can easily unload frozen cargo which is stuck to the wall of a car.

Accordingly there is provided, an unloading machine comprising a first frame having a moving frame 'M' which is slidable along an inner guide rail 'R' attached on the inner side of the first frame, and having first and second opposed unloading apparatuses each comprising: a cage movable along a further guide rail and having a rotatable member attached thereto, an operating arm connected to the rotatable member, a blade arm connected with the operating arm and with a scraper, a first cylinder operable to move the operating arm upwards and downwards and a second cylinder operable to move the blade arm forwards and backwards, a third cylinder operable to move the scraper to a plurality of positions, the unloading machine further comprising a third unloading apparatus attached to the moving frame 'M' and comprising:: a bracket member moveable in a direction perpendicular to the guide rail 'R', a slide bar received in the bracket member and fixed between two end plates of the bracket member, a fourth cylinder operable to move the bracket member in a direction perpendicular to the rail 'R', an operating arm connected to the bracket member, a blade arm connected to the operating arm to which a bucket is fixed, a fifth cylinder connected between the bracket member and the operating arm, and a sixth cylinder connected between the operating arm and the blade arm.

The invention also provides an unloading machine having a fixed frame consisted of several steel bars 'F-I, F-2, F-3' and shaped a hexagonal frame fixed above usual rail 'R', a moving frame 'M' slides along inner guide rail 'R' attached on the inner side of steel bar 'F-l' and extending along rail 'R' with cooperation of roller 7 of moving frame 'M' comprises; a pair of unloading apparatuses A-l facing in opposite direction consisted of; a moving cage A-10 moves along guide rail 8 by the operating cylinder 4 and has a pinion 3 connected with a motor 2 to rotate spur gear 1 made on the rotating shaft 6.

an operating arm 15 connected with the rotating member by pin 5.

a blade arm 10 connected with the said operating arm 15 at its middle position by pin 5' and with a scraper 14 which is a bucket and can be used as a scraping blade.

a cylinder 12 makes the operating arm 15 move upward and downward and a cylinder 13 lets the blade arm 10 move forward and backward.

a cylinder 11 makes the said scraper 14 to be at a certain inclined position. and another unloading apparatus B-l assembled on the said moving cage 'M' and consisted of; a bracket member 30 which do not rotate but just moves in a vertical direction of rail 'R' with cooperation of guide rail 28 and another roller 8 attached to bracket frame 30.
