FIELD: agriculture.SUBSTANCE: wide-coverage tillage combine comprises a frame (1) with a towing hook (2), pneumatic wheels (3), the middle movable spragger (5), side movable spraggers (8) with impellers (10) and transport wheels (9), "?"-shaped leashes (19). Bracing wires consist of two parts: front - short (12) and rear - long (18)ones. The bracing wires comprise fingers, springs, catchers and latches. On the movable spraggers (5, 8) the removable paired racks (22) or removable single long racks with zig-zag spike tooth harrows (24) are fixedly mounted with adjustable along the length anchor chains (23). The bracing wires are fixed by retainers in the form of corners with cut-outs and provided with horizontal axes. The removable single long racks are interconnected with braces and form rigid systems. On the removable single racks two rows of zig-zag spike tooth harrows can be mounted. The removable single long racks are made folding. The rails and toothed semi-wheels are fixed on the folding parts of the removable single long racks. Drive of the rails is carried out by hydraulic cylinders.EFFECT: simplification of the design of the unit, elimination of breakage of the bracing wires and folding the unit at turns and U-turns.3 cl, 6 dwg |
