摘要:
An agricultural device includes a number of row units that each includes a seed furrow opener that creates a furrow in the soil for seed placement. Each row unit is mounted to a toolbar of the device by a four-bar linkage which allows each row unit to move vertically to adjust to the contour of the soil independently of the other row units on the same toolbar. The four-bar linkages include one or more springs which work to transfer weight from the toolbar to the row unit. An actuator varies the tension in the spring thereby adjusting the down or up force applied to the row unit.

A seeding boot, for a seeding apparatus mountable on a tyne, or adjacent a soil-opening disc, of a tillage implement, has a hollow boot body mountable adjacent the lower end of the tyne or lower portion of the soil-opening disc. A seed distributor in the boot body has a seed inlet connectable to a source of seeds; at least one seed outlet spaced laterally from the tyne or soil-opening disc; and at least one fertilizer or chemical distributor located rearwardly of the tyne or the soil-opening disc. The seed outlet(s) are provided at, or adjacent, the distal ends of laterally-extending hollow wings, which extend from the seed distributor. When two fertilizer or chemical distributors are provided, the first distributor is connected to “dry” or “granular” fertilizer; while the second distributor is connected to “liquid” fertilizer or chemical(s); the outlet from the second distributor is located intermediate the tyne or soil-opening disc and the outlet from the first distributor; and the outlets of the first and second distributors are at a reduced depth in the soil relative to the seed outlet(s).

At least one set of a double-disc ploughshare (7, 8) and one depth-guide roller (9) is arranged on the frame (6) of a pneumatic precision seeder. Said depth-guide roller (9) is arranged between the two disc ploughshares (7, 8) when viewed in the direction of travel and both ploughshares (7, 8) and the depth-guide roller (9) rotate in the same direction.
摘要:
La présente invention concerne un semoir (1) comportant un châssis (2) composé d'une poutre avant (5) supportant des outils ouvreurs (6) et d'une poutre arrière (7) supportant des outils semeurs (8), les outils semeurs (8) s'étendent derrière les outils ouvreurs (6), chaque outil ouvreur (6) comporte un dispositif pour la fertilisation. Le semoir (1) est remarquable en ce que la poutre arrière (7) est liée au châssis (2) par l'intermédiaire d'un parallélogramme déformable (11) transversalement à la direction d'avance (A), le parallélogramme déformable (11) comporte au moins deux bras articulés (12, 13) et un élément de verrouillage (14) prévu entre deux côtés consécutifs du parallélogramme déformable (11).

The present invention concerns a single-grain seeder having a chassis that supports at least one seeding element (3) comprising a dispensing housing (7), at least one opening disk (8) for opening a furrow in the ground and at least one depth control wheel (9), said dispensing housing (7) delivering seeds one by one via a rotary dosing element intended to turn about a rotation axis (11), each seed being ejected from the rotary dosing element at an ejection point (12) extending in the lower portion of said rotary dosing element. The single-grain seeder is remarkable in that said ejection point (12) is disposed in the external diameter of said opening disk (8), when viewed along the rotation axis (11) of the rotary dosing element.
