Abstract

The invention relates to the excavation of soils and can be used in the construction of excavators that develop heavy soils in places where drilling and blasting operations cannot be carried out for preliminary loosening. The purpose of the invention is to reduce the energy intensity of the development of heavy soils. The bucket of the excavator contains the bottom 1, the front wall 2 having the shape of an isosceles triangle, and side walls. The latter are made of vertical upper parts 4 and lower parts 5 having cutting edges 6 and inclined at an obtuse angle to the front wall 2. The base of the front wall 2 is fixed to the bottom 1, and the cutting edges 6 of the side walls converge at its tops. When the bucket is introduced into the ground by the action of teeth 9 and 10 and cutting edges 6, large pieces are separated from the array and fill the bucket without jamming. 3 il.

Description

1

The invention relates to the excavation of soils and can be used in the construction of excavators that develop heavy soils in places where drilling and blasting operations cannot be carried out for preliminary loosening.

The purpose of the invention is to reduce the energy intensity of the development of heavy soils.

Fig, 1 shows the excavator bucket, side view; in fig. 2 - the same, top view; in fig. 3 is a view A of FIG. one.

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 at an obtuse angle to the front wall 2 with a cutting edge 6 located at an acute angle of cutting. The front wall 2 is made in the form of an isosceles triangle, the base 7 of which is fixed on the bottom 1. The cutting edges 6 of the side walls 3 converge at the top 8 of the front wall. The bucket is provided with teeth 9 placed on the cutting edges 6 and a tooth 10 mounted at the top 8 of the front wall 2.

Bucket excavator works as follows

Maneuvering the boom and excavator arm, the bucket is led to the array so that the base 7 of the isosceles triangle of the front wall 2 is slightly elevated relative to its top 8 with the tooth 10, and inserted into the array in the direction corresponding to the movement along the side walls 3 without jamming. Under the action of a pressure force developed by the boom and excavator hand, the bucket enters the massif to a certain depth depending on the properties of the soil. After that, the bucket is given a certain upward rotation with simultaneous feeding by the hand. When this bucket impact teeth 9 and 10 and cutting edges B separates

from the array, large pieces of soil, which, moving without jamming along the front wall 2 and between the lower parts 5 of the side walls 3, fill the space between the bottom 1 and the upper parts 4

side walls 3 Thereafter, the bucket is retracted from the array and unloaded.

Claims (1)

Claims of an excavator bucket comprising a bottom, a back wall, an anterior wall extending thereto and side walls, each of which has a vertically placed upper part and a lower part inclined at an obtuse angle to the front wall with an acute cutting angle located at an acute angle of cutting The fact that, in order to reduce the energy of the bone development of heavy soils, the front wall is made in the form of an isosceles triangle, the base of which is fixed to the bottom, while the cutting edges of the side walls c d are in the top of the front wall, and the ladle is equipped with teeth arranged at the apex of the latter and on the cutting edges ..
