Description

The invention relates to the construction engineering machine building and can be used on scrapers, bulldozers, grader elevators and other earth-moving machinery.

The purpose of the invention is to expand the functionality of the earthmoving machinery.

Figure 1 shows the working body of the earthmoving machinery; figure 2 - section aa in figure 1.

The working body of the earthmoving machine consists of a convex knife

1c is curved in plan, with a cutting edge, of a foot plate 2, made in the form of a knife 1, which is connected by means of a hinge 3 to a bracket fixed on the back side of the bottom 4 (ground guide element), a scraper bucket, hydraulic cylinders 5 are installed on the side walls bucket 6, associated with footboard

2 using the hinge 7, the movable base plate 2 and the bottom 4 are connected by means of an elastic element 8.

The device works as follows. .

When performing planning works, the convex semicircle of the cutting edge of the knife 1 when cutting is placed in such a position that its projection onto the frontal plane is depicted as a straight line segment. Therefore, when removing the surface layer, the trough has a flat shape.

When it is necessary to work on denser soils, the hydraulic fluid is fed into the hydraulic cylinders 5 rotations, which turn it over.

plate 2 with the knife 1 fixed on it on the hinge 3, cutting the edges of the knives while cutting takes up such a position that its projection on

frontal plane depicted as an arc. In this position, the earthmoving machine works like a knife with a curvilinear shape, and with the help of hydraulic cylinders 5, turning the base plate 2, the arc curvature and cutting angle can be changed, which affects the efficiency of the earthmoving machinery.

Extending forward sidewalls

6 Buckets prevent soil going to the sides and thus contribute to improving the performance of the earthmoving machinery. The use of the elastic element 8 prevents the soil from entering the area between the movable footplate 2 and the bottom 4. The protuberance of the knife reduces its thickness by increasing its rigidity, which is provided by this form of knife. Cutting of the soil occurs with the effect of oblique cutting, which reduces the energy intensity of the work.

Soil ,, cut with a knife shavings

of a certain thickness, enters the bucket and, due to the convex shape of the knife, accumulates at the side walls. At the final stage of filling; bucket lifting of the soil column is facilitated, as well, as the soil column in such a bucket is compressed by the pyramids of the soil, and not by prisms as would be observed when flat knives are pierced, which contributes to an increase in the filling ratio.
