(S) EXCAVATORY BUCKET WITH DOUBLE-CHARGED DOWNLOAD SYSTEM

I

The invention relates to excavator-type excavating machines, namely single-bucket excavators, and is aimed at improving their design.

Known attachments are designed mainly for the development of frozen soils with an additionally mounted ripper and mounted on a common axis with a bucket, relative to which they are rotated using DI hydraulic cylinders.

However, this equipment does not allow performing a whole range of other works in construction, apart from loosening frozen soils. They are not provided with the performance of the stripping and planning works, the digging is carried out only by the front edge, which, compared to the two-knife system, has an increased duration / cycle. In addition, the location in the front of the ripper in the front end limits the operating parameters of the excavator equipment.

The closest technical solution to the invention is an excavator bucket with a double-slotted loading system comprising a rear wall, a front wall with a main cutting edge and a rear loading slot, side walls and an attachment located under the front wall.

10 with an additional cutting edge and mounting arms covering the side walls, which are connected to the control cylinders of the attachment | 2.

The disadvantage of the known bucket is that its design only provides for excavating the soil and carrying out the stripping work.

The purpose of the invention is the expansion

20 bucket technological capabilities.

This goal is achieved by the fact that the side walls are made with t-slits directed from the front of the V. jHeM walls to the rear, and the connection of the mounting levers with hydraulic cylinders is made of hinge rods, which are connected to the assembly levers by means of fingers mounted in the grooves of the side walls, and mounted on the back side of the double-arm levers, whose shoulders are connected by means of joint pins and hydraulic cylinders, while the prefix has loosening teeth attached to its back side. In addition, the bucket is equipped with a jaw gripper attached to the rear of the front wall. Nafig shows a bucket when digging soil with a front cutting edge or grabbing goods; Figure 2 is the same when digging soil at the same time but with two cutting edges; on fig.Z the same, when loosening the Soil. The excavator bucket includes a front wall 1, a main cutting edge 2, for example, in the form of teeth, mounting loops 3, side walls. In the front wall 1 there is a loading slot 5 across the entire width of the bucket, from below which adjoins attachment 6 with mounting levers 7, is equipped with a cutting edge 8 at the front, and at the opposite end - with a loosening tooth 9 - fingers 10 are mounted at the top of the levers 7, which installed in lateral vertical slots 11 in the cteHKax 4 bucket, while the fingers 10 are connected to the side arms 12, having two shoulders levers 13 and connected to the control cylinders I. And on the back side of the front wall 1 after the slit 5 a gripping jaw 15 is mounted , image The ripper 9 (FIG. T) is a gripping tool body. Two shoulders levers mounted on the rear wall 16. The bucket works as follows. When cutting soil with a small chip thickness, the main cutting edge 2 initially interacts with it, which destroys this soil and the digging force causes this soil to move along the wall in front of it (Fig. 1). With an increase in the thickness of the cut soil chips, the cutting edge 8 participates in the cutting, which inserts it into the soil when the hydraulic cylinders pull out. In this case, the levers 13, f4 12 side rods and the levers 7 are activated. The soil enters the bucket through the slot 5 (Fig. 2. When it is necessary to seize any cargo or loosen the frozen and frozen soils, with the help of alts 10 levers 7 in such a way that the cutting edge 8 joins to the cutting edge 2. When the bucket moves in the opposite direction of digging, the loosening tooth 9 realizes the development of strong soils (when loosening or seizing loads between the loosening tooth 9 and the gripping jaw 15. Thus Thus, the use of such a structure the bucket allows it to be adapted to different working conditions, reduce the energy consumption of the digging process, thereby increasing the versatility of the excavator equipment. 1. Excavator bucket with a two-slot loading system, including the rear wall, the front wall with the main cutting edge and rear loading slot, side walls and an attachment box under the front wall with an additional cutting edge and mounting arms covering the side walls, which are connected to the control cylinders detecting the prefix, characterized in that, in order to expand its technological capabilities, the side wall formed with slits directed from the front wall to the rear and bond assembly of levers with hydro. cylinders are made of hinge rods that are connected to the mounting levers by means of fingers mounted in the grooves of the side walls, and from double-arm levers mounted on the back side of the rear wall, whose arms are connected respectively to the hinge rods and hydraulic cylinders, while the attachment is mounted on the back side loosening teeth., 1, about t of l and h 2.
