(54) DEVICE FOR UNLOADING BULK CARGOES

(37) The invention relates to loading devices and can be used for unloading tubers, such as potatoes, from covered railway cars or from a warehouse. The goal is to increase efficiency by reversing the intake conveyor.

The device for unloading bulk cargo contains installed on self-propelled chassis 1 dump 4 and intake 3 conveyors. On the shaft 9 of the intake conveyor 3 is installed a screw 10, made in the form of pins mounted on rings with rubber lugs 15. The rings are rotatably mounted relative to the shaft of the screw, on which two stops are installed for engagement with the corresponding fingers of the screw. The stops are located along two screw lines of the opposite direction, which makes it possible to change the screw winding while reversing the rotation of the screw shaft. When the device is in operation, the intake conveyor can move the material to both the upper and lower branches, while the auger feeds the material to the intake conveyor. 1 z.Po f-ly, 6 ill.

The invention relates to loading and unloading devices and can be used to unload a club of non-root crops, such as potatoes and covered railway wagons or from a warehouse.

The purpose of the invention is to increase efficiency by ensuring that the intake conveyor is reversed,

Figo shows a device for unloading, a general view; figure 2 - the same; on fig.Z - raking auger on fig, 4 - section aa on fig.Z; on fig.Z - node 1 in figure 4; figure 6 - scan of the screw shaft with stops.

The device contains a self-propelled chassis 1, on which an inclined intake conveyor 2, made with plastic-scraper with transport chute 3, and dump KOHBefiep 4, is mounted. The traction body of conveyor 2 is two sleeve-roller chains, on which plates are scraper 5 the combs with flexible tips 6 made of elastic materials, such as a rubber tube, and flooring 7. Shaft 8 and 9 form a deviation on the plate-scraper conveyor 2 sections of breaking, collecting, lifting and reverse movement of scrapers. On the lower deflecting shaft 9, driven in rotation by the conveyor chains, the rakes 10 are fastened. Each of the rakes 10 consists of a hollow shaft 11, on the outer surface of which annular grooves 12 are made. Opposite each of the grooves 12 are installed with the possibility of free rotation relative to shaft 11; outer rings — 13, each of which has a finger 14 with a tip 15 mounted on it from a rubber tube, with the part of the finger 14 that protrudes along the inner diameter of the ring 13 with a guaranteed A locking ring 16 is mounted on the shaft P to prevent the rings 13 from holding the longitudinal movement of the rings 13. To limit the angle of rotation of each of the rings 13 as it rotates, two stops 17 are installed in each of the grooves 12 of the shaft 11. on two screw lines of the right and left directions (fig.b).

The device works as follows.

The self-propelled chassis 1 enters the carriage before the interaction of the sections of the collapse and intake of the lamellar-scraper conveyor 2 and the scooping augers 10 with the unloaded cargo. The drive of the conveyor 2 is activated. When the scrapers 5 pass through the inclined frontal area of the collapse between the deflecting shafts 8 and 9, the load slope collapses. The final filling of the scrapers 5 takes place on the lower deflecting shaft 9 when the scrapers move downwards and the conveyor of the lower working branch (along the transport chute H) operates during unloading or on the upper deflecting shaft 8 when moving

scrappers 5 upwards and the conveyor’s operation with the upper branch along the decking of the lamellar-scraper conveyor 2 (for example, when unloading clogged potatoes, beets and other root crops larger than 100 mm), the rowing screws 10 with the right and left winding lines transport the unloaded load with the sides of the device to the center, i.e. to the scrapers of the lamellar-scraper conveyor 2. At the same time, the fingers 14 of the screw 10 under the influence of the resistance forces of the load on them turn with the rings 13 relative to the shaft 11 until the lower

the guide part of the fingers 14 with the stops 17 installed in the grooves, ensuring the arrangement of the fingers 14 along the respective helix. When you change the direction of motion

the conveyor 2 changes the direction of rotation of the screws 10 to the opposite. Under the influence of the resistance forces of the load on the fingers 14, the latter are rotated with rings 13 along

grooves on shaft 11 to the side opposite to the direction of rotation of shaft 11, before interacting with other stops 17. Placing the stops 17 along two intersecting screw lines

determines in the process of work the arrangement of the fingers 14 along the screw lines of the right or left winding. I

So when reversing

rotation of the screws 10 under the influence of the load resistance forces on the fingers 14, depending on the direction of rotation on the screws 10, changes the direction of winding of the helix (left

right and vice versa) and as a result, the direction of transport by the augers 10 of the load remains constant to the plate-scraper conveyor 2.

Next, the transported cargo is moved by the plate-scraper conveyor 2 to the place of unloading on the dump conveyor 4. The dump conveyor 4 moves the cargo from the place of unloading of the plate-scraper conveyor 2 to the doorway of the car.
