3.9
Design and diagram of hydraulic system of feeding mechanism is shown in figure (3.4). This
system is used for controlling the floor conveyor. The hydraulic system is supplied from the
tractor's external hydraulic system through hydraulic conduits (4) and (5). Conveyor
movement direction depends on direction of hydraulic oil flow in the motor (2) which drives
the feeding mechanism via reduction gear (3).
ATTENTION
In order to identify the conduits, labels with arrows are located near the connection
plugs. The arrows indicate direction of hydraulic oil flow through hydraulic motor.
Hydraulic conduits of the system are marked with black plugs.
The floor conveyor operation is controlled by means of the manifold in the tractor cab. Such a
solution enables quick change of conveyor movement direction and shortens reaction time.
Conveyor movement speed is adjusted with flow regulator knob (1) within scale from 0 to 10.
The flow regulator is installed on the outrigger in the front section of the manure spreader.
The maximum flow rate (maximum conveyor speed) is achieved if flow regulator setting is 10,
while the minimum flow rate is achieved if flow regulator setting is 0.
3.2.4 DRIVE TRANSMISSION
Spreader unit is driven by the drive transmission system whose design is shown in figure
(3.5).
Torque is transmitted from the tractor PTO to the manure spreader's mechanisms via PTO
shaft with shear bolt clutch (1). Torque from shaft (1) is transmitted to reduction gear of the
spreader unit drive (4) via power transmission shaft (2) and PTO shaft with unidirectional
overload clutch (3).
ATTENTION
For a given type of manure spreader, do NOT use PTO rotation speed other than
specified in table 3.1.
If PTO shaft works at a different speed, rotation speed of spreading wormshafts will be
insufficient and the drive will be at the risk of damage.
