Description

The invention relates to loading and unloading operations in transport and can be used when loading bulk materials into a moving train of gondola cars.

The purpose of the invention is to increase efficiency by preventing loss of materials during transportation from aerodynamic effects.

In FIG. 1 schematically shows the proposed device, General view; in FIG. 2 — section A — A in FIG. 1; in FIG. 3 view B in FIG. 1.

The device consists of a feed conveyor 1, a receiving storage hopper 2 with a shutter 3. A vertical telescopic chute consisting of a stationary chute 4 and a movable chute 5 equipped with a drive 6 for raising and lowering is rigidly attached to the hopper.

The receiving storage hopper 2, the vertical stationary trough 4 and the movable trough 5 are equipped with a vertical telescopic partition 7, which forms two separate cavities 8 and 9. In the upper part of the receiving storage hopper 2, a classification grid 10 is mounted having an angle of inclination towards the cavity 8. The slots between individual grates of the classification grid 10 are expanded in the direction of movement of the material.

The outlet of the movable chute 30 ba 5 is limited by stepped walls. The protruding walls are limited by the cavity 9. The ends of the walls of the movable trough 5 are made concave with a cutout to form a “cap” of large fractions of the cargo in the gondola car 11. ³⁵

The device operates as follows.

Bulk material is conveyed by conveyor 2 to the surface of the classification grid 10. The material, moving along the inclined surface of the grid, is divided into a small fraction falling into the cavity 9, and into a large fraction directed by the classification grid into the cavity 8. When the shutter 4 is closed, the material accumulates in the cavities 8 and 9 of the receiving ¹⁰ storage hopper 1. When filling the cavity 8 with the first, the large fraction rolls down through the telescopic vertical partition 7 and enters the tank 9, mixing with the fine fraction, ₁₅ t. e. bulk material without separation supplements the tank 9.

When the next gondola car is fed for loading with bulk material, the shutter 4 opens and the material from the cavities 8 ²⁰ and 9 enters the gondola car 11. The beginning of the gondola car tank 11 is loaded when the fractions are mixed until the material is supported with the end face of the steps of the lower part of the movable trough 5.

With further movement of the gondola car 11, its capacity is filled with small or mixed fractions of the material from the cavity 9 to a height with the formation of a “cap” caused by the end face of the protruding step of the telescopic gutter. The end face of the less protruding stage of the telescopic trough forms the upper layer of the “cap” from a large fraction of the material of the cavity 8. Considering that the bulk of the material for loading comes from the cavity 9, it should be made larger.
