(54) WORK BODY OF THE SINGLE BUCKET

(57) Uses: multi-purpose single-bucket loaders. Essence

invention: the bucket contains the bottom, rear and side walls. The hinged front parts are attached to the fixed parts of the side walls. On the rear wall of the bucket are mounted hydraulic cylinders turning the front parts of the side walls. On the lower edges of the latter there are clamps in the form of mushroom fingers. The fingers enter the arcuate grooves of the bottom. The bucket is provided with removable clips for fastening the exchangeable working equipment to the front parts of the side machines. 8 il.

The claimed invention relates to multi-purpose multi-purpose loaders and is intended to increase the efficiency of use of the loader.

Structures of single-bucket loaders are known that are designed for loading and unloading operations, including a base machine, an arrow and interchangeable working parts (see A.F. Bazanov, G.V. Zabegalov. Self-propelled loaders, M., Mashinostroenie, 1979). The main disadvantage of these loaders is that the working body performs a strictly defined type of work, cannot be used in other works without human intervention, and its replacement requires the obligatory use of manual labor when removing the old one, installing and fixing a new working body. Moreover, it is not possible to carry on a minimum of equipment for carrying out a complex of works.

The closest to the technical nature of the present invention is a bucket known for and.with. № 1199867, CL.E 02

F 3/40. In the known device, including the bottom, the back wall and the side walls, the latter are made of a fixed part rigidly connected to the bottom and the back wall, and the front part hinged to it, provided with a fixture of its position. Performing the side walls of the bucket in a known device with composite parts allows the bucket to work with both bulk and long loads.

A disadvantage of the known bucket is to make the front part of the side walls passive, which limits the use of the bucket.

The purpose of the proposed invention is to expand the technological capabilities of a known working body. The goal is achieved by the fact that in a known bucket, including the bottom, rear wall, side walls containing rear fixed parts and front parts hinged to them and clamps of the latter, the bucket is equipped with hydraulic cylinders for rotating the front parts of the side walls and removable clamps for

the attachment of the interchangeable working equipment to the latter, on the bottom, are made arcuate slots, and the anchors are rigidly attached to the lower edges of the front parts of the side walls and have the shape of mushroom fingers arranged so as to move in the arcuate grooves of the bottom.

Such a working body provides a significant expansion of the technological capabilities of single-bucket loader.

Figure 1 shows a general view of a single-bucket loader bucket; figure 2 is a top view of the bucket; on fig.Z - section aa in figure 2; figure 4 is a view of the bucket, equipped with clamping jaws, when capturing a piece of cargo; figure 5 is a view of the bucket when they capture hollow piece goods; figure 6 is a view of the bucket when using the pivoting walls as a collider; figure 7 is a view of the bucket when capturing hollowed piece weights with a centrally mounted pin using pivoting walls as pushers; Fig. 8 is a top view of the bucket with extensions attached to the side walls of the bucket for scooping.

The tool body of the single-bucket loader (Figs. 1, 2, and 3) forms the bottom 1 with the horizontal knife 2, the rear wall 3, the side walls made of composite and consisting of the fixed part 4 and the front part 5 hingedly attached to it. To the front of the side walls there are attached mushroom-shaped clips 6 (Fig. 3), placed in the arcuate grooves 7 of the bottom 1 with the possibility of movement in them. The grooves in the bottom are made along the radius and are covered with a casing 8 on the bottom. On the front parts of the side walls there are levers 9, connected through pull 10 and pivot link 11 with hydraulic cylinder rods 12, the housings of which, in turn, are hinged on the back side of the bucket 3 . Removable clips 13 are fastened to the pivoting parts of the side walls.

The tool body of the single-bucket loader is completed with clamping jaws 14 (Fig. 1), pins 15 (Fig. 5), extension pieces of the side walls 16 (Fig. 8). Removable clamps are used for mounting on the pivoting parts of the side clamping jaws 14, pins 15, extension cords 16.

Swiveling the front parts of the side walls with its fixed part and supplying them with a turning drive allows them to be installed in the usual position, spread out to the sides and fold into the bucket. In the first case, loading and unloading operations are carried out as with

conventional front bucket. When operating a loader with light bulk loads and snow removal, when the pressure forces are small, in order to increase productivity, the side walls are parted to the side and in this case they play the role of an expansive

To allow the bucket to pick up long loads, the side walls

sideways or set inside the bucket in a closed position. In the latter case, when unloading side walls, you can push the load from the bottom. When working with sticky weights side walls, set before scooping in the closed position, you can forcibly push the load from the bottom and clean it.

The proposed loader may also perform loading and unloading operations with piece goods. In this case, the bucket elements (side walls, bottom, rear wall) are gripped with clips. When working with large piece loads with

clamping jaws 14 (Fig. 4) are mounted on the side walls by means of clamps.

During the work with hollow piece loads (pipes, rings, etc.) on lateral

the walls are mounted with clips pins 15 (Fig. 5). Turning the side walls, plant the ends of the pins into the open ends of the product and its grip. Unloading is performed by diluting the side walls.

Pivoting sidewalls can be used as cargo pushers from the bottom of the bucket (Fig. 6). The pins can also be mounted on the back wall of the bucket (Fig. 7). In this case, the pre-folded side walls can act as a collider,

When mounted on the back wall of two parallel pins, it is possible to load and unload cylindrical piece goods, such as barrels.

Loading small piles of garbage, sand,

bulk cargo scattered in a thin layer using a conventional front-end loader bucket is ineffective due to the fact that the load does not enter the bucket as it moves forward, but is collected in front of it in the form of a drag prism. In the proposed device for increasing the coefficient of filling the bucket on the side walls with the help of clamps install extenders 16 (Fig.8). Turning the side walls, along with the extension cords, towards the bucket, the cargo is piled up and forced into the bucket.

Thus, the equipment of the loader bucket with active side walls will significantly expand its technological capabilities, improve the use of the loader, and consequently, the efficiency of its use.
