Arable Injectors
The Terrasoc arable injector is made of a galvanised double-beam frame with two rows of rigid tines with very flat “duckfoot” shares at their ends (24 cm wide). The shape of the tines and the wide opening of the shares ensure a very good flow of the slurry and a wide distribution. The distance between the tines is 40 cm and the distance between the 2 rows is 70 cm. This wide spacing prevents any clogging of the soil and crop residues as well as the "rake" effect. Slurry is usually injected on a 10 to 12 cm working depth. The standard gauge wheels allow to limit the injection depth. The shear bolt security protects the tines against destructive obstacles. As a summary: the Terrasoc is the ideal injector for sandy and stony grounds.
Arable injectors make it possible to inject slurry deeply. They also loosen the ground. They are fastened on a double-beam frame reinforced by radiant crosspieces. The main advantage of this assembly is that it focuses 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: wide 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 certified road lighting system.
The slurry, flowing through a hose having the same shape as the tine, is laid down under the foot of the share making a groove in the ground. With the Terrasoc, slurry is injected over the entire width of the share (from 15 to 24 cm depending on the type of slurry and ground), which contributes to a high spacing between the tines, as well as less tractor power. The 200/60-14.5 rubber gauge wheels (Ø 605 x 210 mm) allow a central adjustment of the working depth. The tines are individually adjustable in 3 positions. The same principle allows to modify the sloping angle of the tines to loosen the ground more or less effectively.
As slurry (especially cattle slurry) contains fibres and foreign substances, it is essential to have an efficient macerator for the injector to work properly. Yet, a blocked opening means an uneven spreading pattern. The user therefore has to stop working and clean the machine, which is quite constraining! The JOSKIN solution is the patented system of macerator with cutting and self-sharpening discs: the JOSKIN SCALPER©. The cutting system of the SCALPER© is merciless: free rotating circular blades are fitted on a knife holder driven by a hydraulic motor. There is a scissor effect between the circular blades and the arched and off-centre elliptical openings of the counter blade (HARDOX), inevitably cutting all materials that can appear in the slurry. If the blades hit something hard, the rotation direction of the SCALPER© is reversed by the ‘‘Switch-Matic’’ system (option) until the obstacle is chopped. Furthermore, an electric reverser with manual control is installed in the cab for all rear implements with automaton. The JOSKIN macerator is assembled by fitting and clipping. A multi-position manual valve, fixed at the macerator inlet, provides a step by step adjustment of the injector feeding. The precise adjustment is carried out by means of the pressure relief valve and the chosen type of counter blade. The hydraulic circuit is isolated thanks to a cap. A drain cap can be used to detect a possible defect in the hydraulic seal.
The Terrasoc injectors with a working width larger than 3 m are standard fitted with a hydraulic folding system. Folding is easy thanks to the action of the powerful hydraulic rams. In transport position, the total width of the Terrasoc does not exceed 2.70 m (2.85 m on model 5200/13SH).
The injector is fitted with a support that can be hitched to the standardized 3-point linkage of a tractor. In this way, it can be used as a simple stubble plough or with an umbilical system.
