The shaft 1 beam 2 is provided with an additional element 5 made in the form of a lever, one end of which is rigidly fixed on the shaft 1 beam 2, and a second end pivotally connected hard thrust 6 with the frame of turn 7. Additional link 5 from the axis OIIshaft 1 beam 2 to the axis OIIIhinge 8 attachment 6 together with a thrust of 6 between the axis OIIIhinge 8 attachment 6 and the axis OIVhinge 9 attachment 6 to the frame of turn 7 is formed by two link OII-OIIIand OIII-OIVarticulated chetyrehzvennoy. The third and fourth links are formed by the frame of turn 7 from the axis OIVhinge 9 attachment 6 frame move to the axis OIrotation of the turntable 3 and a plot of the rotary platform 3 from the axis OIrotation of the turntable 3 to the axis OIIshaft 1 beam 2.

One ends of the cylinders 10 pivotally connected with the head plate 2, which is mounted on the shaft 1 can be rotated relative to the shaft 1, and the second ends secured to the plate 11, which is fixedly mounted on the shaft 1 beam 2.

The engine is turning moldboard boom bucket wheel excavator as follows.

formed by the frame of turn 7 from the axis OIVhinge 9 attachment 6 frame move 7 to the axis OIrotation of the turntable 3 remains stationary. Links OI-OIIand OIV-OIIIformed a plot of the turntable 3 and the hard thrust of 6, are rotated together with the rotary platform 3 (see Fig.3). Link AboutII-OIIItogether with the plate 11 and the head plate 2 when moving remains parallel to the fixed link of the site OIV-OIthe frame of turn 7. Thus by rotating the turntable 3 heaped boom bucket wheel excavator is not rotated. The end of the moldboard boom remains above the place of unloading. A small lateral movement of the boom in this case can be compensated for by the unequal length of the opposite links of the articulated chetyrehzvennoy. When the moving plate 11 and the head plate 2 is deviated from a parallel position relative to the fixed link OIV-OIthe frame of turn 7, providing movement relative to the latter. To change the designated unloading include drive rotation of the bar. The cylinders 10 of the drive beam 2 carry out the rotation of the bar 2 relative to the plate 11.

The rotation mechanism moldboard boom bucket wheel excavator with change is intended to consolidate the moldboard boom bucket wheel excavator. The shaft 1 mounted on the rotary platform 3 and offset from its axis of rotation. In this mechanism the axis of rotation of the turntable is a geometric axis OIpassing through the center of a turntable 4 turntable 3. The shaft 1 beam 2 is provided with an additional element 5 made in the form of a lever, one end of which is rigidly fixed on the shaft 1 beam 2, and a second end pivotally connected hard thrust 6 with the frame of turn 7. Additional link 5 from the axis OIIshaft 1 beam 2 to the axis OIIIhinge 8 attachment 6 together with a thrust of 6 between the axis OIIIhinge 8 attachment 6 and the axis OIVhinge 9 attachment 6 to the frame of turn 7 is formed by two link AboutII-OIIIand OIII-OIVarticulated chetyrehzvennoy. The third and fourth links are formed by the frame of turn 7 from the axis OIVhinge 9 attachment 6 frame move 7 to the axis OIrotation of the turntable 3 and the plot of the turntable 3 and from the axis OIrotation of the turntable 3 to the axis OIIshaft 1 beam 2.
