The invention relates to road construction machines, in particular, to emleroynyh machines such as bulldozers.

The aim of the invention is to expand the operational capabilities when working on easily developed loose soils.

FIG. 1 shows dozer equipment, general side view; in fig. 2 - the same, front view; on ig. 3 - the same, with the jaw partially parted and replaced to the side; on ig. 4 - the same, with a fully opened jaw; in fig. 5 - the same, when capturing bulk materials; on ig. 6 - the same when digging the soil with a blade.

Bulldozer equipment includes pushing bars 1, blade 2 with knife 3 and side cheeks 4, front jaw 5 connected to blade 2 with its sides b and 7 hingedly. The jaws of front jaw 5 are made of sections 8 and 9, one above the other and fixed section 8 on the side 6 and section 9 on the side 7. The hydraulic cylinder 10 of the bilateral action of sliding the sides 6 and 7 of the front jaw 5 is mounted between the upper ends of the sides.

The upper rod 11 is attached to both ends of the side of the cheeks 4 blade 2. The lower horizontal rod 12 is installed with the possibility of rotation relative to the upper rod 11 in the vertical plane between the cheeks 4. The rod 13 of the hydraulic cylinder 14 turns

the front jaw 5 is attached to the middle part of the housing of the hydraulic cylinder 10 extending the front jaw 5, and the lateral parts of the housing of the hydraulic cylinder 10 are pivotally connected to the upper rod 11 by brackets 15. The knives of sections 8 and 9 are made with two opposite cutting edges 16 and 17. Each section 8 and 9 is pivotally mounted on the lower shaft 12 by means of lugs 18 and 19 rigidly connected to sections 8 and 9. The lugs 18 are connected to corresponding sidewalls b and 7 by means of pins 20 with cotter pins 21. Sections 8 and 9 have the possibility of fixed rotation and on the rod 12. For this purpose, additional through-holes 22 are formed in the sidewalls 6 and 7. The hydraulic cylinder 14 is connected to the hydraulic cylinder housing 10 by a detachable hinge 23. Both rods 11 and 12 have grooves 24 for the axial movement clamps 25 along the sidewall blade 6 and 7. Front the edges of the side cheeks 4 are made with teeth 26 located against the hollows of the teeth 27 formed on the back side of the sidewalls 6 and 7.

The equipment works as follows.

When digging the ground with a knife 3 blades 2, the rod 13 of the hydraulic cylinder is retracted and the front jaw is turned upwards (FIG. 6). When developing a more solid soil

The rod 13 of the hydraulic cylinder extends by acting on the body of the hydraulic cylinder 10 and turning the front jaw down to the stop of section 8 and At the knife of the jaw into knife 3 O1 call 2. W reaped rods hydro5164

cylinder 10 provides the minimum width of the soil digging knife jaw (Fig. 2). The sides 6 and 7 are fixed in this position by the clips 25 in the slots 24 of the rods 11 and 12.

When developing less solid ground, the clips 25 on the outer side of the sidewalls 6 and 7 are pulled out and when the rods of the hydraulic cylinder 10 of the sidewall 6 and 7 are extended, they move apart, moving along the blade parallel to each other sections j and 9 of the jaw knife before setting the required width of the soil digging with a jaw knife, after The sidewalls 6 and 7 are fixed by the clips 25 in the slots 24 of the rods 11 and 12. The extension of the rods of the hydraulic cylinder 10 is limited by the side cheeks 4 of the blade. Sidewalls 6 and 7

ke loose soil. In this case, the maximum width of the soil digging with a jaw knife (Fig. 4) is achieved.

If it is necessary to work in cramped conditions, for example, with the right edge of the blade, the latches 25 of the sidewall 6 are removed, the rods of the hydraulic cylinder 10 are extended and the sidewall 6 with the section b is moved to the required position in which it is fixed by the latches 25 in the slots 24 of the rods 11 and 12 ( Fig. 3).

When grabbing bulk materials, the fingers 20 are removed, sections 8 and 9 are rotated relative to the rod

12 and are fixed with fingers 20 in the free openings 22 of the sidewalls 6 and 7.
