3.5
Manure spreader design is shown in figure (3.1). The manure spreader consists of a V-
shaped monocoque load box (1) connected with rigid single axle system (2). The front wall
has an inspection opening for controlling the load movement inside the load box. The axle
system is equipped with large wheels which ensure low rolling resistance and facilitate
travelling on wet ground and towing the manure spreader.
The support (7) is attached to the front wall of the load box. The support is used for
supporting the manure spreader during parking, when the machine is not hitched to the
tractor, and for adjusting the drawbar eye height when hitching the machine to tractor. The
manure spreader is hitched to the tractor using the lower drawbar with shock absorber (3)
and rotating drawbar eye (5) or ball drawbar eye (12). Optionally, the manure spreader can
be equipped with upper drawbar (4) with fixed drawbar eye (6). NV161/4 manure spreader
and NV161/5 manure spreader are equipped with drawbar with shock absorber (13).
Ladder (8) for climbing on top of the load box in order to perform cleaning or maintenance
work is attached to the left wall of the load box. Wheel chocks are placed on the right wall. In
the rear section of the manure spreader there is a PTO driven vertical spreader unit (9) with
two wormshafts. Slide gate (10) can be additionally installed between the load box space and
the spreader unit. The manure spreader can be additionally equipped with tailgates (11) to
prevent load spill during transport and limit the manure spreading width during fieldwork.
3.2.2 FEEDING MECHANISM
The feeding mechanism in NV161/1 and NV161/2 and NV161/3 manure spreaders consists
of transfer unit (1), tensioning unit (2) and drive unit (3) – figure (3.2) . The feeding
mechanism in NV161/4 and NV161/5 manure spreaders consists of two transfer units (3),
two tensioning units (2) and a drive unit (3) – figure (3.3).
The transfer unit consists of two chains (4) and scraping strips (5) bolted to the chains. The
chains in the rear section of the manure spreader's load box are seated on cast iron gear
wheels of drive mechanism shaft (3). The chains in the front section of the manure spreader's
load box are seated on the front wheels of the tensioning unit (2).
The transfer mechanism is driven by hydraulic motor (6) which rotates drive mechanism shaft
(3) via reduction gear (5). Chain wheels are mounted on the drive mechanism shaft. The
rotating chain wheels cause shifting of transfer unit.
