Abstract
A blade preferably adopted to work machines for digging, carrying of soil and leveling, which achieves an increase in a quantity of soil per tractional force with a simple structure to reduce consumption horsepower and increase fuel consumption efficiency thereby leading to low cost, has a central front face section (12) having a linear first cutting edge (15) at a bottom end thereof, a jointed front face section (13) having a second cutting edge (16) which continues from the first cutting edge (15) and extends backward at a predetermined angle, and an end front face section (14) having a third cutting edge (17) which continues from the second cutting edge (16) and extended forward at a predetermined angle.
Claims15
A blade to be mounted on various kinds of work machines, comprising:
- a central front face section and end front face sections disposed at right and left end sections thereof via jointed front face sections, wherein
- a bottom end of each of the jointed front face sections and a bottom end of each of the end front face sections are disposed backward of a bottom end of the central front face section when viewed from their tops,
- the bottom end of the central front face section is extended in right and left directions perpendicularly to a digging direction, and
- width W1 at the bottom end of the central front face section is larger than internal width W0 between right and left traveling units.
A blade to be mounted on various kinds of work machines, comprising:
- a central front face section and end front face sections disposed at right and left end sections thereof via jointed front face sections, wherein
- a bottom end of each of the jointed front face sections and a bottom end of each of the end front face sections are disposed backward of a bottom end of the central front face section when viewed from their tops, and
- blade width W1 at the bottom end of the central front face section is substantially equal to gauge width WG which is a distance between right and left traveling unit centers.
