Product soil.
Fig. 4 is the structural schematic diagram that the utility model embodiment provides that bull-dozer pushes away ditch operation, as shown in figure 4, when bulldozing
When machine carries out pushing away ditch operation, hydraulic cylinder 6 is stretch up and down in vertical direction, pushes away ditch and shovels 4 descending depths by hydraulic oil
6 piston stroke of cylinder determines that maximum descending depth must not exceed piston range, the minimum width for pushing away ditch shovel 4 of groove width,
Groove width can be expanded by multiple reciprocating working, maximum width must not exceed crawler belt spacing.When needing to carry out backfill operation,
6 piston retraction of hydraulic cylinder pushes away ditch shovel 4 and is raised to extreme higher position to minimum stroke, pushes away ditch shovel 4 with dozer 1 and forms an entirety,
Dozer lower adjustment on the whole is controlled by left lift cylinder 3 and right lift cylinder 2, to complete backfill operation.
The bull-dozer except have conventional type have soil-shifting, it is smooth, push away the functions such as hole, backfill in addition to, also have push away narrow ditch, zanjon
Etc. functions；By about 6 telescopic adjustment of hydraulic cylinder, that realizes different depth pushes away ditch operation, repeatedly reciprocal by bull-dozer, can
That realizes different in width pushes away ditch operation.Structure is simple and convenient to operate, and can satisfy in present engineering construction that pipeline is embedded etc. to be wanted
It asks.
