Description

(54) BUCKET EXCHANGER WITH DOUBLE-ROW DOWNLOADING SYSTEM

one

The invention relates to earth moving machinery, namely to single-bucket excavators.

An excavator bucket with a two-purpose loading system 1 is known. It is effective only in homogeneous soil conditions, since it is not possible to adjust its parameters during operation.

The closest technical solution to the invention is an excavator bucket with a double-track loading system, comprising a rear wall with mounting lugs, a main body part with side walls, a cylindrical bottom and a rear edge, a rotary and spring-loaded relative to the rear wall an attachment with side walls, a bottom and a front cutting edge 2.

The disadvantage of such a bucket lies in the absence of self-adjustment of its parameters when working on dissimilar soils.

The aim of the invention is to expand the technological capabilities of an excavator bucket with a double-slot loading system.

The goal is achieved by the fact that the attachment is located inside the main part of the body and is pivotally connected to the 11th side of the rear wall, the bottom of the FSNIIO / IHe io casing is cylindrical with the middle loading slot, and the main body part; the side walls through a hinge located coaxially with the hinge of the prefix, is connected with the rear wall and has a rotational drive relative to the latter.

On fis. I shows a general view of an excavator bucket when operating with two cutting edges. in fig. 2 the same when working with one cutting edge.

Claims (2)

The excavator bucket includes a prefix consisting of side walls 1, a cylindrical bottom 2 with a middle loading slot 3, a front cutting edge 4. The attachment is pivotally connected to the rear wall 5 and is located inside the main part of the body consisting of the side walls 6. of a cylindrical bottom 7 and the rear cutting edge 8. The main part of the body is also pivotally connected to the rear wall 5 and has a rotational drive relative to the latter, including 9 and a hydraulic cylinder 10. The prefix by means of a flexible rod 11, passed through the guide role to 12 connected to the spring 13. Since the outer side of the rear wall 5 mounted nrounshny assembly 14 for connection with an excavator kov1na Tew handle. When connecting the bonded soil, the ladle is converted according to FIG. 1. The soil in the digging process is cut out by the front cutting edge 4 and the rear 8 at the same time and pushed into the bucket. If 3 large pieces, for example stones, get into the loading slot, the dimensions of the large width of the slot, the attachment rotates relative to the hinge of the fastening clockwise, while increasing the width of the shell, which ensures the passage of an oversized piece of material inside the bucket. When the attachment is rotated, the spring 13 is stretched under the force exerted by the flexible tube 11. The prefix returns to its original position under the action of the energy of the extended spring 13. Under the operating conditions of the excavator bucket, the minimum width of the loading shell 3 is set depending on the type soil, its moisture, strength, lumpiness. The largest size of the loading shell is established when the hydraulic cylinder 10 extends. At the same time, the main part of the bucket body turns counterclockwise and side walls 6 abuts against the rear wall 5. To reduce the width of the slit, the hydraulic cylinder 10 should be reversed. lumpy, and also with stony inclusions of soils. The maximum size of the sheel is also necessary when developing wet. sticky and waterlogged soils, when there is bad unloading of its internal capacity. When digging loose soil, the bucket with the help of hydraulic cylinder 10 is rotated clockwise until the cutting edges 4 and 8 are combined and form a single continuous cutting edge (Fig. 2). Claim of the invention Excavator bucket with two-way loading system, including rear wall with mounting eyes, main body part with side walls, - cylindrical bottom and rear cutting edge, swivel and spring-loaded relative to the rear wall attachment with side walls, bottom and front cutting edge , characterized in that, in order to expand the technological capabilities, the prefix is located inside the main part of the body and is hingedly connected to the front side of the rear wall; ying cylindrical with an average loading slit, as main body portion botyuvymi walls by a hinge disposed coaxially with the hinge pivot prefix associated with the rear wall and has a rotation drive with respect to the latter.
