Abstract

The invention discloses a device for absorbing and separating railway ballast bed sand deposition. The device comprises a separation compartment body (3'). The front part of the separation compartment body (3') is connected with a corrugated pipe (1') through a bend air pipe (2'). The corrugated pipe (1') is connected with a sand absorbing fan cover (23'). A sand discharging device (27') is installed at the lower portion of the separation compartment body (3'). The rear portion of the separation compartment body (3') is connected with an air suction fan (14') through an air exhaust corrugated pipe (13'). A conveying device (15') is installed below the sand discharging device (27'). The interior of separation compartment body (3') comprises three compartments which are the first separation compartment (4'), the second separation compartment (9') and the third separation compartment (11') from front to back in sequence. A railway ballast bed sand removal vehicle comprising the device for absorbing and separating railway ballast bed sand deposition comprises a vehicle frame. A driver cab is installed in front of the upper portion of the vehicle frame. A power house and an electric generator are installed behind the driver cab. A sand blowing fan is fixedly installed in the middle above the vehicle frame. The device for absorbing and separating railway ballast bed sand deposition is installed at the portion, behind the sand blowing fan, of the vehicle frame. The device comprises the separation compartment body (3').

Description

technical field [0001] The invention relates to a device for absorbing and separating deposited sand on a railway track bed, in particular to a device for absorbing and separating deposited sand on the surface of a railway track bed, belonging to the technical field of engineering equipment. Background technique [0002] There are a large number of railways built in windy and sandy areas in our country. In spring and autumn, strong winds will roll the sand around the railways to the railway track bed, which will affect the running speed of the train in the slightest, increase the wear between the train wheels and the rails, and bury the track bed and rails in severe cases. If it falls, it will affect the normal operation of the train. [0003] At present, the manual cleaning method is adopted for the accumulated sand. After the sandstorm, a large number of workers are organized to sweep away the accumulated sand on the railway track bed to ensure the normal operation of the ...
