(54) LOADING MACHINE BUCKET.

one

The invention relates to machines for loading and transporting various materials, in particular to machines such as single-bucket loaders.

Known bucket single-bucket front loader, including side walls and the bottom 1.

The disadvantage of this bucket is that the front cutting edge, made along the straight line, provides increased resistance to its introduction, which reduces the efficiency of the loader.

The closest to the proposed technical essence & and the achieved result is a bucket of the earth-moving machine, including jaws mounted on a common vertical axis, and a drive for rotating the jaws, made in the form of hydraulic cylinders. During the operation of the bucket, its jaws under the action of hydraulic cylinders, when inserted into the material, are turned to the outside. The poi front bucket cutting edge consists of two wedges, the force for insertion of which is lower than the ASE / IGN required for insertion of the bucket with a straight cutting edge. By

as the bucket is filled, the jaws are closed under the action of the hydraulic cylinders. Then the bucket is raised to the transport position and the material is transported to the place of unloading 2.

Its disadvantage is that a hydraulic system with power cylinders is used to open and close the jaws. This complicates the design of the bucket as a whole.

The purpose of the invention is to simplify the bucket design.

This goal is achieved by the fact that the drive is made and the form of a spring

5 compression with rods, the spring has a body, and the rods are pivotally connected to the back walls of the jaws.

FIG. 1-3 depicts a bucket in different positions.

The loader bucket contains a boom 1 and two jaws 2, which with the help of earrings 3 and a finger 4 are fixed on the boom 1 so that both half-jaws can be turned around the finger in the outer sides. On the rear wall of each floor, there are stops 5 on the outside, connected by rods of a cylindrical spiral spring SHINE 7, enclosed in a cylindrical

cue case 8. On the bottom sheet of the boom 1 at its front edge mounted thrust protrusion 9.

The bucket works as follows.

Before being introduced into the stack, the bucket is in the ORIGINAL position (Fig. 1), in which both half of the bucket are closed. When the bucket is inserted into the head on the front edge of the bottom of the jaws 2, there is a force of resistance to penetration that creates a torque that causes both jaws 2 to turn to the outside on the earrings 3 relative to the finger 4, and with the help of stops 5 and rods b compresses the cylindrical helical spring 7. The bucket (Fig. 2) is inserted into the stack, and its implementation occurs with less pressure than if the bucket was solid. After the bucket is fully inserted into the stack, its lifting begins, and the force, resistance to insertion acting on the front edge of the jaws 2, and jaws under the action of the compressed spring 7, rotate around the finger 4 and close, and the side walls of the bucket

grab the captured material from the sides into the middle of the bucket and thereby increase its content.

A bucket with a spring-loaded turn of the jaws makes it possible to eliminate a complicated hydraulic system, in connection with which the machine as a whole becomes simpler and cheaper.
