SPREADING DEVICE FOR THE APPLICATION OF BRAKE SAND ON RAIL-MOUNTED VEHICLES

摘要

A spreading device for a pneumatic application of brake sand on rail-mounted vehicles, comprising an air source and a sand container as storage container for the brake sand or the spreading material, an outlet at the lower end of the sand container, a connecting pipe to a mixing container provided for air-charged swirling of the spreading material to form a sand stairway and a dispensing device disposed on the mixing container for the specific dispensing of the spreading material onto the rails in front of the wheels.

主权项

1. Spreading device (1) for the pneumatic dispensing of a free-flowing spreading material (2) on rail-mounted vehicles, comprising a sand container (3) with an outlet opening (31) and a connecting pipe (6) at the lower end of the sand container with a further outlet opening (61) at the lower end of the connecting pipe, a mixing container (5) substantially enclosed in an airtight manner on all sides with cover (51) and base (52) with inner ventilation floor (54) and an outlet (57) with adjoining dispensing device (7) for the spreading material, an air source (4) with an air line (41) and an air inlet (55) into the mixing container, as well as a sand staircase, wherein the sand container as storage container contains the spreading material and the spreading material can trickle as a result of weight force through the outlet opening (31) into the connecting pipe and through the further outlet opening (61) into the mixing container and can be deposited on the ventilation floor, wherein the outlet opening (61) at the lower end of the connecting pipe forming the sand staircase lies lower than the outlet (57) of the mixing container, wherein the air inlet (55) is disposed below the ventilation floor and spreading material deposited on the ventilation floor can have air from the air source flowing through from bottom to top and mobilized spreading material (2) can be dispensed as air-spreading material mixture through the dispensing device (7) from the spreading device (1).
