SOLODISC XXL General Points

General Points

The Solodisc XXL is a versatile disc injector, ideal for high-precision spreading on all types of arable lands, and especially on meadows. Available with several working widths, it is made of a galvanised single-beam frame with free-steering elements. Each of them is fully galvanised and fitted with a pair of discs, with a 18.75-cm spacing, followed by injection cones. Thanks to the large diameter of the discs (Ø 400 mm x 20 mm), it can also work on stubble fields, young plants, and also on meadows. Its special feature is the adjustable working depth (max. 6 cm), which is kept constant by applying a continuous pressure on the linkage. For a more precise spreading, this injector can be equipped with a section control that, thanks to an ISOBUS control and a GPS system, locates the areas that have already been fertilised and automatically closes the appropriate injection hoses.

SOLODISC XXL Discs

Discs

The Solodisc XXL is fitted with 20 mm thick self-sharpening discs with a diameter of 400 mm that are assembled on hubs with large watertight conical bearings (which can be tightened up). Made up of metal, rubber and NBR nitrile, these discs are extremely sturdy and ensure a long lifespan to the Solodisc XXL. Specially designed for JOSKIN, they are lighter than solid discs for an equivalent sturdiness. Thanks to their diameter, the required traction power is less high. They make a groove in the soil (max. 6 cm) so that the injection cone can lay the slurry homogeneously in the heart of the groove, without damaging the vegetation and ensuring a faster penetration into the soil. After the disc has done its work and the slurry has been injected, the groove closes naturally due to the normal pressure of the soil ("ice skate" effect).

SOLODISC XXL Structure and Working Principle

Structure and Working Principle

The Solodisc XXL is made up of a galvanised single-beam frame (galvanisation at the galvanising plant of the JOSKIN group) with free-steering elements that are each fitted with a pair of self-sharpening discs (Ø 400 mm x 20 mm) followed by 2-position injection cones. The discs have an 18.75 cm spacing. As far as the injection cone is concerned, it is made up of a galvanised spout, an anti-drip pincer and a very flexible injection cone in profiled rubber. The ideal working depth is 3 cm. It can be adjusted (0-6cm) and it is kept constant by means of the application of a constant pressure on the linkage. The pressure has simply to be changed by means of an easy-to-reach handle to adjust the working depth. This adjustment is usually made at the beginning of the work and is easily adapted according to the soil moisture and conditions at the time. Springs on the free-steering elements are used as mechanical shock absorbers and push the discs on the ground with a given pressure. Furthermore, they limit the injection depth variations and allow a vertical movement of each element of approx. 10 cm in order to face transverse ground unevenness. As an option, the springs can be replaced by a hydraulic cross-compensation system keeping the same ground pressure for each element (communicating vessels principle). Regarding the compactness for journeys on public roads, the models are fitted with a double acting (DA) hydraulic folding system in order to comply with the required transport width. Once the injector is folded, the elements on the upper arms are kept in position by a locking system. A simple notch prevents each element from making a rotation round its axis and from falling down. The elements remain thus very rigid in relation to the vibrations due to transport. The folding system is also 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. The Solodisc XXL has a very compact frame: this design allowed to bring the opening discs as close as possible to the frame beam, thereby limiting the overhang on the linkage.

SOLODISC XXL Pincers

Pincers

The JOSKIN Solodisc XXL injectors are standard fitted with anti-drip pincers with hydraulic closing system. They automatically open the injection pipe as soon as the injector hits the ground (and inversely when it 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. In addition, they can work with the section control (option) to avoid spreading on areas that have already been fertilised, thereby ensuring an even more precise spreading pattern.

SOLODISC XXL Free-Steering Elements

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 20° in bends (10° to the left and 10° to the right) without lifting the machine nor damaging the meadow. These free-steering elements are fully galvanised for a long lifespan.

SOLODISC XXL Eccentric Scalper Macerator

Eccentric Scalper Macerator

The macerator is of utmost importance in order to make sure the spreading implement works properly. Regardless of the spreading width, the Solodisc XXL is equipped as standard with two vertical macerators to reduce the reaction time at the start of the spreading work as well as the pressure losses (more even spreading pattern). This macerator has a variable opening of the counter blade, which allows an extremely precise dosing of the quantity to be spread, regardless of the desired flow. A hand-accessible thumbwheel allows the operator to change the flow rate according to the type of material and quantity of material to be spread. The macerator has a single knife unit in the form of a diabolo that rotates eccentrically on the Hardox counter blade for an even distribution. The central venting system through the middle of the diabolo with two inlets allows a smooth flow in the various hoses to the ground, without suction effect. This compact macerator is equipped with quick-opening side covers and a stone trap for a quick and easy maintenance.
