Minisize snow removal frostproof machine for railway crossing

The utility model discloses a minisize snow removal frostproof machine for a railway crossing, which comprises a shell (1), a heating device (2), a draught fan (3) and a transformer (4). The end part of the shell is provided with of an air inlet (1-1), and the inside of the shell is communicated with two ends; the heating device (2), the draught fan (3) and the transformer (4) are arranged inside the shell; and the heating device (2), the draught fan (3) and the transformer (4) are connected by a conduction wire. With the adoption of the minisize snow removal frostproof machine for the railway crossing, the heating device heats the air, the draught fan blows hot air flow to the railway crossing so that the temperature among the railway crossings rises, rain and snow can not be easily solidified, or ice snow attached on the railway crossings is thawed; due to the connection of the minisize snow removal frostproof machine for the railway crossing and a control cabinet of the railway crossing, the power source i
