This invention relates to a mining transport, in particular to bucket loading machines.

The purpose of the invention is to increase the reliability of the machine at large angles of rotation.

Figure 1 shows a diagram of a bucket loader, general view on. Figure 2 - the same, top view; figure 3 is a section aa in figure 2; figure 4 - loading machine with a rotated platform, top view.

The bucket loading machine includes code part 1 with a turntable 2, on which is mounted the turning platform 3, the lifting mechanism 4, the bucket 5 on the handle 6 and the power cylinder 7 turning the platform. On the turntable 3, an automatic turner is installed, made in the form of a profiled drum 8 and connected to the left wing of the armorti 6 by means of levers 9 and 10.

On the undercarriage 1 on the axle 11, located on the longitudinal axis of the undercarriage, but displaced relative to the axis of rotation of the platform 3, a swivel lever 12 is installed, at one end of which a roller 13 is fixed, interacting with the profile drum 8, and on the other the end of the lever 12 is installed slider 14 with the possibility of turning in the lever 12 and in contact with the profile sleeve 15, forming a groove in

When the platform 3 is rotated by the cylinder 7, the platform rotates the pivoting lever 12 through the slider 14, the pivot 13 of which does not leave the zone of action of the profiled drum 8. Thus, with this lever system and the movable roller 13, the pivoting automatic device when tilting swivel bucket at a greater angle.

This is achieved by means of a pivoting lever enabling the bucket to be centered at the time of its unloading into the vehicle.
