BUNKER TRANSFORMATION MECHANISM Russian patent published in 2013 - IPC A01F12/60 A01D41/12 

FIELD: agriculture.

SUBSTANCE: invention relates to agricultural machine building and may be used in design of bunkers of agricultural machines. The bunker transformation mechanism 21 has a front 1, a rear 2 and two side 3, 4 sections of the roof, rigid triangular sections 6, a hatch 25, a linear electric mechanism 18 and a loading auger 17. The front 1, rear 2 and two side 3, 4 sections of the roof are hingedly fixed on the body of the bunker 21. Rigid triangular sections 6 are arranged at the corners of the bunker 21, and its front 1 and rear 2 sections are connected with the side 3, 4 sections. The hatch 25 is fixed to the rear 2 section by means of a hinged loop 23 and a collet. The front 1, rear 2 and two side 3, 4 sections of the roof are connected with levers 8, 12 of longitudinal 7 and transverse 11 torsions. The longitudinal torsion 7 is connected with a traction rod 16, connected with a loading auger 17. The linear electric mechanism 18 by one end is connected with the bunker body 21, and by its other end - with the loading auger 17.

EFFECT: bunker transformation mechanism 21 provides for increase of its volume in working condition with preservation of transport size of a combine.
