(54) BUCKET EXCAVATOR

I

This invention relates to working bodies of excavators, in particular, to their buckets.

A excavator bucket is known, in the walls of which there are openings for the passage of soil when it is being cut with additional knives located opposite said openings 1.

Another known technical solution is an excavator bucket comprising a back wall, side walls and a bottom, e with a rezush, its edge, rectangular openings and opposite rectangular knives opposite npoev, attached to the side walls and bottom 2.

The disadvantage of this bucket is the relatively high power consumption of the cop; and the ground.

The purpose of the invention is to reduce the energy intensity of digging soils of different densities.

This is achieved by the fact that in the excavator bucket, containing the back wall, side walls and bottom with rectangular openings and straight lines opposite to the openings, are attached to the side walls and bottom, each

the side wall is set at an angle to the longitudinal axis of the bucket, equal to 5-7 °, the apex of the angle is located in front of the rezhushy edge of the knife side wall.

The width between the knives of the side walls is equal to the width of the back wall of the bucket, and the openings are made in the middle part of the bucket.

FIG. 1 shows an excavator bucket; in fig. 2 - view A of FIG. one; in fig. 3 - bucket, side view; in fig. 4 - view B of FIG. 3

The excavator bucket contains the rear wall 1, as well as the side walls 2 and 3 and below 4 with the rectangular openings 5, 6 and 7 made in them and the straight knives 8, 9 and 10 located opposite the openings. The knives are attached to the side walls and the bottom. ,

The side walls and the blades are arranged parallel to the vertical axis 11 (Fig. 4) of the bucket, while the side walls are set at an angle to the longitudinal axis 12 of the bucket and are divergent to the rear wall 1.

The angle o between each side wall 2 and 3 of the bucket and its longitudinal axis 12 is chosen to be 5-7 °. The width between the knives of the side walls 2 and 3 is chosen as the slave width of the nalny walls of the bucket 1. Gaps 5, 6 and 7 in |. | 11 are full in the middle part of KOBiJi;). KOIUII has a front knife 13. KOBHI works as follows. When the soil is coianin, the front knife 13 and 10 are successively inserted into it. At the same time, the soil enters the bucket through its open front part and through the opening 7. This reduces the resistance to cutting the soil. At the same time, the ground is also cut off with knives 8 and 9 and, entering the COB1I through nrohems 5 and 6, goes to the sides and to the back wall 1 along the side walls 2 and 3 that are spread to the sides. This reduces the resistance to ground movement in KOBUI . Claims 1. An excavator bucket comprising a rear wall, side walls and a bottom with rectangular A-2 .2 rectangular openings and rectilinear straight knives opposite the openings attached to the side walls and characterized in that in order to reduce the energy intensity of digging soils of different density, each wall is set at an angle to the longitudinal axis of the bucket, 5-7 °, and the top of the angle is located in front of the cutting edge of the side wall knife. 2. Excavator bucket according to Claim 1, characterized in that the distance between the cutting edges of the side walls is equal to the width of the rear wall of the bucket.
