PROJECT PRESENTATION
Only by utilizing modern harvesting and conserving technologies of fodder plants and
through the appropriate endowment with performant tractors and machines, able to achieve
high working indexes, little fuel consumption with minimum losses and diminished
manpower we can obtain high quality fodder at a low cost price.
The main objective of this project is to achieve a modern technical equipment designed
to mowing, crushing and forming cautions herbaceous fodder, which should be manufactured
by SC „MECANICA CEAHLĂU„ Piatra Neamţ.
Destination
The technical equipment for mowing, crushing and forming continous furrows of
herbaceous fodder-named trailed windrower for fodder harvesting is designed to perform
the operation of mowing, crushing and laying on the soil as a continous and uniform furrow
the herbaceous fodder aimed to the naturally dried. According to the tackled working
technology the fodder plants in the furrow can be gathered and chopped when they reach
50…55% humidity for low humidity ensling or can be let to dry till around 20%, after what
they are gathered and stored as bulk hay or bales of hay.
The trailed windrower works in aggregate with 45…65 HP tractor, being coupled to the
draw bar, the working parts being driven from the PTO through a cardan drive. At the same
time, the windrower can work with any wheeled tractor which is equipped with a II nd
category three point hitching device draw bar with holes at its rear part and power take off
with 540 rot/min rotative speed .
The windrower can be used at herbaceous fodder plant harvesting: vegetables
(lucerne, trefoil) vegetable mixtures with herbs from the lawns situated on slope fields which
be easy to access by the tractor in the aggregate.
Constructive description
The trailed windrower VTR mainly comprises the following sub assemblies:
- harvesting equipment;
- running frame;
- transmission.
The harvesting equipment represents the machine part which performs the mowing,
crushing and laying down the mown fodder on continous furrow and comprises the
following parts: frame, incling device, plant crushing device, transmission.
The frame is a metallic structure made of pipes, plates and welded sections of
different shapes and sizes and for coupling on running frame it is endowed with a coupling
device with jointed rods.
The cutting apparatus is of double forged fingers type and knife with cutting plates with
normal cutting, being driven by an oscillating washer mechanism.
The inclining device is the cam-type, being endowed with four bars with elastic fingers.
The inclining device position can be adjusted in comparison with the cutting device
according to the green matter production per hectare.
The fodder crushing device comprises two finned metallic rolls, placed behind the
cutting apparatus. The upper roll can vertically float depending on the plant layer thickness
which passes through the crushing device and the lower roll is in a fixed position. The
upper roll presses on the plant layer passing through the crushing device by means of its
two helical springs situated at the roll’s end, endowed with tension screw designed to adjust
the pressing force.
In order to adapt the crushing device to different fodder harvesting, the upper roll is
manufactured in two variants: a metallic variant with inclined ribs recommended for
crushing the plants which are more resistant during the shaking process and a rubbered
surface variant designed to fodder plants which are sensible to shaking (lucerne, trefoil).
The running frame, is the windrower component part which ensures the displacement
both during the work process and the transport. It is mainly composed of the following
assemblies :welded frame running wheels, hitch and hydraulic installation.
The running wheels are of low pressure tyre-type being placed behind the frame, at its
extremities by means of two hinged tension members. The running wheels are similar to
those used on the fodder trailed combine CTF.
The hitch is situated on the left side of running frame and the windrower’s coupling to
tractor is performed through its agency. The hitch is hinged on the frame and takes two
distinct positions:
a) When the hitch is right - inclined (towards the machine) it corresponds to windrower
transport position situation in which the tractor’s overall size frames within the
windrower overall dimensions;
b) When the hitch is left inclined (towards the outer part) it corresponds to the working
position and the windrower is laterally – right placed in comparison with the tractor. In
this case, during the work, the tractor overpasses the furrow, which was previously
mown and the windrower’s equipment works on the whole working width in the field to
be harvested.
Taking into account the fact that the latest years within Romanian agricultural farms
are used many types and ranges of tractors internally or externally manufactured,
surpassing 50 HP power, the hitch coupling system to tractor comprises a rotative
mechanism (named GYRODINE), made of two reduction gear boxes with conical gear
wheels which are coupled by means of a bearing axle and a metallic frame, being coupled
on the side tensional bars of three point hitch (of II nd category to left or right) belonging to
relevant tractor. This mechanism allows to coupling frame to rotate with a 90°angle in
comparison with the hitch ensuring a very good mobility of aggregate during the work. At
the same time, the cardan transmission angle which drives the windrower remains
constant, removing this way the danger of deteriorating it when the lifting mechanism is
acted or during larger road curves.
A supporting leg is mounted on the hitch ensuring the windrower’s stability state and
allowing an easy coupling to tractor.
The working equipment is coupled on running frame by means of two lower tensional
bars (sidely placed) and an upper central tensional bar. This mechanism allows to
equipment to reproduce the soil micro-relief during the work both on the displacement
direction and the cross side, the cutting height resulted being uniformly performed.
The working equipment leans upon the soil by means of two shoes (skids) placed to
extremities (by means of which the equipment reproduces the soil) and by whose
adjustment different cutting heights can be obtained depending on the crop to harvest. In
order to diminish the equipment pressing force on soil, the coupling mechanism has been
endowed with two helical springs which take over a part of equipment pressing force on
soil.
For lifting or lowering the working equipment to soil the windrower is endowed with a
hydraulic installation made of two hydraulical cylinders with simple effect and connecting
pipes.
The transmission to windrower’s working parts is mechanical, being constituted of
cardan drive transmissions, angular belts and chain transmissions. The mechanism is
driven from tractor’s PTO through a cardan drive transmission. In order to ensure a
protection against overloads, the transmission is equipped with overload coupling of friction
type.
