Abstract:
A tilting boom applicator broadly includes a laterally- extending applicator boom a lift (24), and a tilt frame (26). The lift includes upper (70) and lower (72) lift arms that support the applicator boom and are operable to vertically shift the applicator boom. The tilt frame (26) interconnects the applicator boom and lift and includes a fixed section (116) mounted to upper lift arms (70) and a swinging (118) section mounted to the applicator boom. The frame sections are attached to each other at a frame pivot joint (194) that defines a longitudinal tilt axis, with the frame pivot joint permitting tilting movement of the applicator boom relative to the lift about the longitudinal tilt axis. Lower lift arms (72) are directly attached to the swinging section (118) to limit movement of the applicator boom relative to the lift about a lateral pitch axis while permitting the tilting movement.
Abstract:
La présente invention concerne une rampe d'épandage de produits (1) pour un appareil agricole d'épandage de produits (2) équipée d'un dispositif de suspension (3) par l'intermédiaire duquel la rampe (1) est destinée à être liée au châssis (4) de l'appareil agricole (2), ledit dispositif de suspension (3) comportant : - une bielle de liaison (6) qui relie ladite rampe (1) audit châssis (4), cette bielle de liaison (6) étant liée audit châssis (4) par l'intermédiaire d'une première articulation (7) d'axe dirigée dans la direction d'avance (A) au travail, et à la rampe (1) au moyen d'une deuxième articulation (8) d'axe également dirigée dans la direction d'avance (A) au travail, - des ressorts (16A, 16B) destinés à agir à l' encontre du pivotement de la rampe (1) autour de ladite deuxième articulation (8), et - des amortisseurs (18A, 18B) destinés à amortir ledit pivotement de la rampe (1) autour de ladite deuxième articulation (8). Ladite rampe (1) est remarquable par le fait que ledit dispositif de suspension (3) comporte en sus des ressorts supplémentaires (2 IA, 21B) agissant entre la rampe (1) et le châssis (4) et que le centre de gravité (28) de la rampe (1) se trouve sensiblement dans le voisinage de ladite deuxième articulation (8), et de préférence quelque peu en dessous de ladite deuxième articulation (8). L'invention concerne également un appareil agricole d'épandage de produits (2) équipée d'une telle rampe (1).
Abstract:
The invention concerns a suspension device (1; 100) for a boom (2) of a product spraying agricultural appliance, comprising elements for mounting said boom (2) on a body (1a; 101a) of said appliance. The suspension device (1; 100) is characterised in that it further comprises means (7, 8; 107, 108, 115) to dampen the boom (2) movements and adjusting members (7, 8; 107, 108) capable of acting on said boom (2) mounting elements so as to vary the position of said boom (2) instantaneous centre of rotation (CIR) relative to its centre of gravity (CG), preferably by modifying the spacing between said centre of gravity (CG) and said instantaneous centre of rotation (CIR) located higher than the centre of gravity (CG).
Abstract:
An apparatus for the spraying of an area of interest (S) of a high-pressure working fluid (V) wherein the apparatus is susceptible to move relatively to the ground (S) along a direction of reciprocal advancement (d) and it comprises at least one tank (2) for the working fluid (V), at least one outlet nozzle (41) and a fluid connecting line (4) extending from the tank (2) towards the outlet nozzle (41). The apparatus further comprises supply means (5) of the working fluid (V) that include a high- pressure pump and at least one spraying device (10) placed along the fluid connecting line (4) the former (5) upstream with respect to the latter (10). Furthermore, the spraying device (10) comprises a support structure (11) that comprises a first plate (12), motor means (35) acting upon the first plate (12) to promote the eccentric rotation thereof around a first axis (Z) and at least one manifold (42) placed on the first plate (12) to move integrally therewith. In particular, the latter (42) comprises at least one outlet nozzle (41) oriented so as to spray a jet of working fluid (V) towards the ground (S). The first plate (12) is mounted movable with said support structure (11) so that upon the movement along the direction of reciprocal advancement (d) of the apparatus (1) and of the ground (S), the jet flowing from the outlet nozzle (41) hits the latter with helical path.
Abstract:
Aperfeiçoamento em barra central para pulverização e/ou distribuição de produtos em que o conjunto da barra (1) é composto por um quadro central (2) que se destina à fixação no chassi do veículo propulsor por meio das travessas do quadro (3) e visa minimizar e suavizar os efeitos das vibrações e trancos que ocorrem durante o trabalho das barras laterais (4), sendo para tanto dotado de um ponto de giro (5) que suaviza os trancos e trepidações longitudinais que ditas barras (4) sofrem durante os deslocamentos no trabalho e nas voltas que o veículo executa.
Abstract:
A self-propelled agricultural application machine (10) comprising a chassis (100) which carries a storage tank (15) for the material to be applied is provided. The chassis (100) comprises a central longitudinal beam (110) from which at least a pair of wheels (12, 14) are suspended. The narrow chassis (100) allows steerable wheels to be positioned at tolerable track widths whilst permitting a large steering angle and thus small turning radii.
