Abstract
A work machine that can discharge water collected inside a casing to the outside, reduce leakage of noise, and reduce entry of foreign matter from outside. The work machine includes a bottom portion cover forming a portion of a casing, and the bottom portion cover includes: at least two ribs and a bead (strengthening structure portions) that are formed substantially perpendicular to a bottom surface of the bottom portion cover; and a drain hole located in a connecting portion connecting the bottom surface of the bottom portion cover and a water-discharging rib among the at least two ribs. An upper portion of the water-discharging rib is located over the drain hole.
Claims6
A work machine comprising a bottom portion cover forming a portion of a casing of a generator,
- the bottom portion cover comprising:
- a plurality of strengthening structure portions formed substantially perpendicular to a bottom surface of the bottom portion cover;
- and
- a plurality of drain holes, each of which is located in a connecting portion connecting the bottom surface of the bottom portion cover and an associated one of the plurality of strengthening structure portions,
- each of the plurality of strengthening structure portions having an upper portion located over the plurality of drain holes, wherein
- the plurality of strengthening structure portions includes a lattice portion formed in a lattice shape and includes:
- two first strengthening structure portions extending in parallel to each other and a second strengthening structure portion intersecting with and being substantially orthogonal to the two first strengthening structure portions,
- the plurality of drain holes comprises:
- a first drain hole formed in the lattice portion at a position of intersection of one of the two first strengthening structure portions and the second strengthening structure portion,
- a second drain hole formed at a location in which the lattice portion is not formed, in a substantially middle portion of a further second strengthening structure portion in a longitudinal direction of the further second strengthening structure portion,
- the bottom portion cover is located at a bottom portion of the casing of the generator to support an engine of the generator,
- the plurality of strengthening structure portions are formed between engine-retaining structure portions for supporting the engine, the engine-retaining structure portions being formed on the upper surface of the bottom portion cover.
