JOSKIN Spreading implements

Structure

Arable injectors make it possible to inject slurry deeply. They also loosen the ground.

They are fastened on a galvanized double-beam frame reinforced by radiant crosspieces. The main advantage of this assembly is to focus the strains of the implement on the tanker, which then transfers them to the tractor. The stress is therefore reduced and the tank is not subjected to distortion.

The basic frame is modular for all models: large width models are manufactured on the basis of the 2.80 m models with extensions.

The frame of the injectors wider than 3 m are fitted with a double-acting hydraulic folding system with anti-twisting safety stop. All these implements are fitted with a road lighting system.

General Points

Meadow injectors make it possible to inject slurry in the ground while avoiding damages to the surface dressing as much as possible.
They are mounted on identical galvanized frames. This standardization makes it possible to interchange the spreading elements.
These single-beam frames are made of high tensile steel offering the best compromise between strength and lightness.
The highly compact design and the folding system of the injector lead to a particularly limited overhang, which allows to significantly reduce the strains at the back of the slurry tanker.

Pincers

JOSKIN injectors are standard fitted with mechanical anti-drip pincers that automatically release the injection pipe when the injection element hits the ground (and inversely when the element leaves it).

Each pincer is fitted with a rounded jaw and a pinching stop in order to limit the wear to the rubber injection cone as much as possible. They can be replaced by hydraulic pincers.

Free steering elements

The injection elements are made up of 2 outlets and are fixed to the frame by means of an axis. They can pivot by 30° in bends (15° to the left and 15° to the right) without lifting the machine nor damaging the meadow.

Lock-Matic

Models that are more than 3 m wide are fitted with a double acting (DA) hydraulic folding system in order to respect the prescribed transport width.

In this case, the folding system is fitted with the Lock-Matic© automatic locking in order to enhance the driving safety as much as possible, namely on the road. This locking device is operated by the same hydraulic function as the folding system, thanks to the steered valves.

Hydraulic folding.

All booms are fitted with a hydraulic folding system that has an insignificant overhang and that does not affect at all the driving of the carriage. During transport, the whole is fastened by a boom clipping system These has a height adjustment device and a craddle with a damping rubber.

The hydraulic folding system has the following specifications:
hydraulic safety device;
locking of the boom wings in transport position thanks to interlocking supports;
diagonally positioned rams (not vertically) to better hold the boom in position (reduction of the swinging movement).

For a higher safety, the folded boom is such that the position of the macerators is pointed inwards so as not to exceed the boom size. From 18 m wide, a double folding system is required.

Macerator

The macerator is of utmost importance in order to make sure the spreading implement works properly. 9 m booms have one single macerator, while those from 12 m have two of them in order to get a greater reactivity at the beginning of the spreading phase and to reduce load losses (slurry is more uniformly spread).

Twist and anti-drip systems

JOSKIN booms (except the TWINJET) are all standard fitted with the (double acting) anti-drip lifting device with Twist system.
It allows a transport in a very clean way thanks to the complete rotation of the line spreading hoses, which prevents any loss of slurry on the road as well as in the fields when manoeuvring.
JOSKIN line spreading booms are standard fitted with the Twist system allowing a 150° rotation of the boom.

Besides this anti-drip function, the Twist system has other advantages:
it offers a limited overhang;
it allows, as an option, to spread with an exact scatterer without having to take off the boom. The macerator and two manual or hydraulic valves just have to be added.

Anti-crash

JOSKIN booms are all standard fitted with the anti-crash device that offer an extra safety when working on hilly ground. Every boom wing is fitted with springs and articulations that, when spreading on a bumpy ground, retract the ends of the boom (max. 55 cm) if it hits the ground. Mounting the wings at the end of the oblong holes allows them to pivot and makes it possible to adjust their height.
