Abstract

Uses: earthmoving machinery for the development of heavy soils. SUMMARY OF THE INVENTION: An excavator bucket comprises a bottom that extends toward the front wall and side walls. The latter have vertical upper parts and lower parts inclined to the front wall with cutting edges. A loosening tooth is fixed on the inside of the bottom. His rack goes through a window in the front wall. The cutting edge of the tooth is located between the geometric line of intersection of the extensions of the lower parts of the side walls of the bucket and the outer side of the front wall. This allows, in case of insufficiency of the pressure force of the earthmoving machine, to loosen the soil by furrows, and then to split the pillars between the furrows. 5 il.

Description

The invention relates to earthmoving machines used in the development of heavy soils, and is an improvement to the device according to the author. St. No. 1661288.

The aim of the invention is to expand the technological capabilities of earthmoving machines.

Figure 1 shows the excavator bucket, side view; FIG. 2 is a view A of FIG. one; on fig.Z - view B in figure 1; figure 4 is a section bb In figure 1; figure 5 - loosening the array.

The excavator bucket contains a bottom 1, a front wall 2 extending thereto and side walls 3, each of which contains a vertically positioned upper part 4 and a lower part 5 inclined to the front wall 2 with a cutting edge 6. The bucket is provided with teeth 7 placed on the cutting the edges 6, and the tooth 8, installed in the top of the front wall 2.

A window 9 is placed in the front wall 2 symmetrically with respect to the longitudinal vertical plane of symmetry of the bucket. The loosening tooth 10 is placed at the base. The loosening tooth base 10 is fixed on the inside of the bottom 1, and its cutting edge 11 is located between the geometric intersection line of the extensions of the lower parts 5 the side walls 3 and the outer front wall 2.

Bucket excavator works as follows.

Bucket cutting edges 6 are embedded in the ground. The tooth 7, as it penetrates into the ground, alternately enters the work, and each tooth 7 that is in front creates a preliminary loosening, facilitating the work of the next one.

In case the pressure force of an excavator when excavating heavy soil is insufficient for

directly scooping, the bucket is pre-loosening. For this, the bucket is turned upwards, the loosening tooth 10 is sunk into the array and the bucket feed is set so that the front wall 2 moves over the loosened surface with the formation of a groove. In this mode, a row of furrows is performed, after which the ground between the furrows is selected by scooping, or the side cleavage of the pillars between the furrows is performed. To do this, the tooth 8 is sunk into the furrow and the angle of the bucket is set so that the loosening tooth 10 enters the furrow to a certain depth. After that, the bucket set feed along the furrow. In this case, the bucket is wedge-shaped, destroying the pillars between the grooves, dividing them in the direction perpendicular to the direction of the scoop.

In the event that it is necessary to carry out the usual digging, the bucket is set the angle at which the cutting edge of the loosening tooth 10 passes over the surface of the massif or furrow. In this position, the bucket enters into the massif without jamming, providing for a particular soil a minimum scooping force. In the process of working on the position of the cutting edge 11 of the loosening tooth 10 relative to the surface

array can be judged on what mode corresponds to a particular angle of attack of the bucket. To do this, it is necessary to support the bucket in the zone of subsequent insertion into the array on the cutting edge 11 of the loosening tooth 10 and at the same time on the top of the tooth 8. las. If it is necessary to make a side split between the furrows, then the bucket must be rotated in the opposite direction.

Claims (1)

Claim of the invention Excavator bucket according to auth. No. 1661288, which is characterized by the fact that, in order to expand its technological capabilities, in the front wall of the bucket a window is symmetrically arranged relative to its vertical longitudinal plane, and the bucket is provided with a loosening tooth placed in the window, the base of which is fixed on the inside of the bottom of the bucket, wherein the cutting edge of the tooth is located between the geometric intersection line of the continuations of the lower parts of the side walls of the bucket and the outer side of the front wall.
