Rain hat for heavy construction equipment

Abstract

A rain hat for heavy construction equipment is disclosed, which comprises a plate which corresponds to a shape of an outlet of the exhaust tube; a connection part which is formed at one end of the plate and is extended in a downward direction; and an elastic plate of which one end is connected with the connection part, and the other end is engaged with the exhaust tube, said elastic plate having a certain length, whereby the outlet of the exhaust tube, which is closed by means of the plate, opens as a discharge pressure overcomes an elastic force of the elastic plate when exhaust gas is discharged from the exhaust tube.

1 . In a rain hat which is mounted on an exhaust tube of heavy construction equipment, a rain hat for heavy construction equipment, comprising:
 a plate which corresponds to a shape of an outlet of the exhaust tube;   a connection part which is formed at one end of the plate and is extended in a downward direction; and   an elastic plate of which one end is connected with the connection part, and the other end is engaged with the exhaust tube, said elastic plate having a certain length,   whereby the outlet of the exhaust tube, which is closed by means of the plate, opens as a discharge pressure overcomes an elastic force of the elastic plate when exhaust gas is discharged from the exhaust tube.   
   
   
       2 . The rain hat of  claim 1 , wherein said elastic plate is a plate spring. 
   
   
       3 . In a rain hat which is mounted on an exhaust tube of heavy construction equipment, a rain hat for heavy construction equipment, comprising:
 a plate which corresponds to a shape of an outlet of the exhaust tube;   a connection part which is formed at one end of the plate and is extended in a downward direction;   a pair of coil springs of which ends are connected with both lower sides of the connection part; and   a bracket which is mounted on the exhaust tube in which the other end of each coil spring is horizontally connected,   whereby the outlet of the exhaust tube, which is closed by means of the plate, opens as a discharge pressure overcomes an elastic force of the coil spring when exhaust gas is discharged from the exhaust tube.
