FIELD: agriculture. ^ SUBSTANCE: deck contains covering and covered sections established on axes. The covering section is connected with axes rigidly, and the covered section is established on them with possibility of axial movement. Both sections consist from side frames, cross-section laths and longitudinal rods and are executed mounted one in another in such a manner that the laths and the rods of each section are placed accordingly between the laths and rods of another section. The cross-section laths of each section are rigidly connected with its side frames, freely established in grooves of another section side frames. At reversive rotation of the screw established in covering section and interacting with a nut, rigidly fixed on covered section, there is a back and forth motion of covered section. At the expense of it there is an alternate narrowing and expansion of apertures decks. ^ EFFECT: effective clearing of deck surface from sticking products. ^ 2 cl, 8 dwg |
