Working machine

Abstract

A working machine includes a machine body, a prime mover provided in the machine body, a hood to cover the prime mover, an operator's seat located above the prime mover, a cooling fan to take in outside air from an outside of the hood to an inside of the hood and cause the outside air to flow to a surrounding area of the prime mover, and a flow regulator to guide a portion of the outside air taken in by the cooling fan to an area above the prime mover.

What is claimed is: 
     
         1 . A working machine comprising:
 a machine body;   a prime mover provided in the machine body;   a prime mover room to house the prime mover;   a hood to cover the prime mover and define the prime mover room;   an operator's seat located above the prime mover;   a cooling fan to take in outside air from an outside of the hood to an inside of the hood and cause the outside air to flow to a surrounding area of the prime mover; and   a flow regulator to guide a portion of the outside air taken in by the cooling fan such that the portion of the outside air reaches an area above the prime mover from the cooling fan through a space within the prime mover room that has an opening to the prime mover.   
     
     
         2 . The working machine according to  claim 1 , wherein
 the hood includes a mount portion on which the operator's seat is provided, and   the flow regulator is configured to direct a portion of the outside air taken in by the cooling fan to the mount portion.   
     
     
         3 . The working machine according to  claim 1 , wherein the flow regulator includes at least one flow regulating plate located on the same side of an upper portion of the cooling fan as the prime mover and higher than the prime mover. 
     
     
         4 . The working machine according to  claim 1 , wherein the flow regulator includes at least one flow regulating plate provided in an inclined manner in which the at least one flow regulating plate is inclined upward with decreasing distance to the prime mover. 
     
     
         5 . The working machine according to  claim 4 , wherein the at least one flow regulating plate provided in the inclined manner includes a plurality of flow regulating plates with a space therebetween in an up-down direction. 
     
     
         6 . The working machine according to  claim 1 , wherein the flow regulator includes at least one flow regulating plate having a flat plate shape or a curved shape. 
     
     
         7 . The working machine according to  claim 1 , further comprising:
 a support frame vertically provided on the machine body inside the hood to support the hood; wherein   the flow regulator is attached to the support frame.   
     
     
         8 . The working machine according to  claim 7 , wherein
 the support frame includes a first-side pillar portion located on one of opposite sides of the cooling fan in a horizontal direction perpendicular to a rotation axis of the cooling fan, and a second-side pillar portion located on the other of the opposite sides of the cooling fan in the horizontal direction;   the flow regulator includes at least one flow regulating plate located on the same side of an upper portion of the cooling fan as the prime mover and higher than the prime mover, and a bracket body attached to at least one of the first-side pillar portion or the second-side pillar portion; and   the flow regulating plate is fixed to the bracket body by a fastener attached from above.   
     
     
         9 . The working machine according to  claim 1 , wherein
 the flow regulator includes at least one flow regulating plate located on the same side of an upper portion of the cooling fan as the prime mover and higher than the prime mover; and   the flow regulating plate includes a cutout portion in a portion corresponding to the cooling fan.
