WORKING EQUIPMENT OF THE EXCAVATOR REVERSIBLE SHOVEL, including a handle with a bucket pivotally connected to the boom, additional equipment and hydraulic cylinders for controlling the bucket, characterized in that, in order to expand technological capabilities, the additional working equipment is made of a rigidly fixed bottom guide rail , carriages with a beam movably mounted on the guide beam and from an additional bucket with a stripping knife hinged on the beam and connected with it by means of hydro ilindra. 2. The equipment according to claim 1, characterized in that, in order to ensure that the bucket is fixed in different positions, the guide beam has holes, and the carriage has a finger.

Description

The invention relates to earthmoving, namely, onHOKOsmoBbnv hydraulic 1-excavator excavators with working equipment backward sloped.

A working equipment of an excavator is known, including an arrow, a handle, a bucket, and control hydraulic grinders lj;

The disadvantage of this excavator is that it does not ensure the performance of Yr doe full-time and other types of work.

The closest to the proposed package is the working equipment of an excavator backhoe, including an arrow arm, a bucket, additional working equipment and control cylinders.

In this additional equipment is made in the form of a blade attached to the bucket 21,

The disadvantages of the known equipment are the limited number of technological operations, as well as the need to repair the equipment for working with a bucket.

The purpose of the invention is to expand the capacity of the city.

This goal is achieved by the fact that in the working equipment of the oOpatHaH excavator, there is a boom, including a boom, a hilt, a bucket, control hydroscopes and additional working equipment, the last of the rigidly fixed bottom of the hilt of the guide beam, on which the carriage with a bar and from an additional bucket with a sweeping knife, hingedly mounted on the beam and connected to it by means of a hydraulic cylinder.

Moreover, the sent ball guide has holes, and the carriage has a finger.

FIG. 1 shows the proposed equipment, a general view ;, in FIG. 2, a bucket with teeth, front view in FIG. 3; an additional bucket with a stripping knife, front view; 4 shows the process of early work with an additional bucket with a finishing knife in FIG. 5 - grab construction materials with an additional bucket.

The working equipment consists of a spreader 1, a handle 2, a bucket 3 with teeth 4, which is controlled by means of a hydrocylinder 5. At the bottom of the handle 2

An additional KOBtu 6 with a clipping knife {knife 7 mounted on a guide beam 8, which is rigidly fixed to the lower part of the handle 2, 5 is mounted. To fix the additional bucket 6 relative to the handle 2 on the beam 8, a series of mounting holes 9 are made with odiyakovymi step. The additional bucket 6 is moved along the beam 8 by means of the carriage 1O, within which movable rollers 12 are mounted on the axles 11, the carriage 10 is rigidly fixed to the bar 13, which is jointly connected with the additional bucket 6 by one KOHUOM and the other 5 end is hinged hydraulic cylinder 14 control. The carriage 10 oi is fixed relative to the beam 8 by means of pins 15 mounted in the mounting holes 9. The excavator equipment operates in the following way.

The development of the soil is carried out with the help of the working equipment of the excavator consisting of the boom 1, the arm 5 2 and the bucket 3 with the teeth 4, the controlled hydraulic cylinder 5. If the need for cleaning works is necessary, the additional bucket 6 is moved along the beam 8 towards the bucket 3 with teeth 4 using the carriage 10, with the finger 15 being dismantled from the mounting holes 9. Cleaning the bottom of trenches and trenches is performed by an additional bucket 6 with a cleaning knife 7 when the excavator works backwards using the boom hydraulic cylinder, arm ( shown) and control 14 gidroshshindra additional bucket 6.

The capture of large stones and construction materials Q is carried out using a bucket 3 controlled by a hydraulic cylinder R and an additional bucket 6 controlled by a hydraulic cylinder 14, while the additional bucket 6 is moved along the frame 8 to 5 opposite side of the bucket 3 and fixed with the help of a rod 15 in the mounting holes x 9.

The use of the invention allows to carry out stripping works for ditches and trenches, as well as to carry out auxiliary works (the seizure and movement of large stones, timber, curb stones).
