Abstract

The invention relates to a lifting apparatus which may be fitted to a front loader. This apparatus comprises a frame 6 mounted on the loader 2, a lifting arm 7, an implement-holder 8 articulated on the arm 9 which itself slides in a cam 10 and allows the orientation of the implement-holder 8 held by the connecting rods 11a, 11b, 11c forming a pentagon which is deformed by the opening or closing of the jack. The apparatus thus designed makes it possible to grasp cylindrical bales of forage laid on the ground by their round part and thus to load them on several levels in a trailer and subsequently to take up these same bales again in order to stack them flat and therefore in columns without using a plurality of jacks and by forming all these different arrangements.

Description

L'invention concerne un surélèvateur adaptable sur un chargeur frontal. Ce surélèvateur fonctionne par l'intermédiaire d'un seul vérin qui étant actionné met en mouvement un système de bielles ; ce qui permet à l'accessoire qui maintient une balle de fourrage de prendre toutes les positions voulues tant au sol qu'à hauteurs intermédiaires ou au maximum de levée. The invention relates to a riser adaptable to a front loader. This elevator works by means of a single jack which being actuated sets in motion a system of connecting rods; which allows the accessory that holds a bale of forage to take all the desired positions both on the ground and at intermediate heights or maximum lift.

Il comprend un bâti (6) pouvant être fixé à la partie supérieure (E) du chargeur (2), un bras élèvateur (7) articule en (A) sur (6), un porte-accessoires (8) articulé en (B), un bras (9) pivotant sur le b ti (6). Les mouvements relatifs de ces quatre éléments (6 ; 7 t B ; 9) sont commandés par un unique vérin (12) dont le corps et la tige (12a) sont respectivement articulés en (F ; G) sur deux éléments voisins (6 ; 7). It includes a frame (6) which can be fixed to the upper part (E) of the loader (2), a lifting arm (7) articulated in (A) on (6), an accessory holder (8) articulated in (B ), an arm (9) pivoting on the b ti (6). The relative movements of these four elements (6; 7 t B; 9) are controlled by a single jack (12) whose body and rod (12a) are respectively articulated in (F; G) on two neighboring elements (6; 7).

Les éléments (6 ; 7 ; 8 ; 9) sont accouplés par les bielles (11 a ; Il b ; 11 c) de longueurs appropriées formant un pentagone déformant par le bras (9) coulissant en un point (D) dans la came (10) avec le porte-accessoires (B) et le bras élévateur (7). Le bras (9) articulé en (B) sur (B) et donnant l'inclinaison du porte-accessoires pour prendre les balles de paille ou de foin debout ou couchées. L'alimentation de l'ouverture et la fermeture du vérin (12) est synchronisée avec le dispositif de commande ; notamment les vérins (5) de commande du chargeur frontal (26 de manière que le porte-accessoires (B) du surélèvateur puisse prendre une balle debout ou couchée au sol ou à partir d'une certaine hauteur au dessus du sol, dans une remorque et permet d'empiler des balles de paille ou de foin ou d'un fourrage quelconque-sur une hauteur relativement grande pouvant atteindre le toit des hangars de stockage. The elements (6; 7; 8; 9) are coupled by the connecting rods (11 a; Il b; 11 c) of suitable lengths forming a pentagon deforming by the arm (9) sliding at a point (D) in the cam ( 10) with the accessory holder (B) and the lifting arm (7). The arm (9) articulated in (B) on (B) and giving the inclination of the accessories holder to take the bales of straw or hay standing or lying. The power supply for the opening and closing of the jack (12) is synchronized with the control device; in particular the front loader control jacks (5) (26 so that the accessory carrier (B) of the jack-up can take a ball standing or lying on the ground or from a certain height above the ground, in a trailer and allows stacking bales of straw or hay or any fodder-over a relatively large height up to the roof of storage sheds.

Claims

CLAIM5

1. Straw or hay bale riser adaptable to a front loader (2) and comprising four elements, in particular a frame (6) which can be fixed to the upper part (E) of the loader (2), at least one hras- elevator (7) pivoting on the frame (6), an arm (9) pivoting on the frame (6) and an accessory holder (8) for catching the balls; riser characterized in that the relative movements of its four elements (6) (7) (B) (9) are controlled by a single jack (12) whose body and rod (12a) are respectively articulated in (F) ( t) on two neighboring elements (6) (7) and that these four elements (6) (7) (e) (9) are coupled together by a system of connecting rods (lia) (1 lb) (? li).

2. Elevator according to claim 1; characterized in that the body and the rod of the jack (12) are articulated, one on the lifting arm (7) and the other on the frame (6) and that the arm (9) slides at a point (D ) in the cam (10) and that the system of connecting rods (lia) (1 lb) (etc) of suitable lengths forms a pentagon with the accessory holder (B) and the lifting arm (7) pentagon deforming by the arm ( 9) articulated in (3) on (e) and giving the inclination of the accessory holder to take the bales of forage standing or lying down.

3. Hoist according to any one of claims 1 and 2, characterized in that the supply of the jack (12) is synchronized with the control device, in particular the jacks (5) for controlling the front loader (2) so that the accessory holder (B) of the elevator can take a ball standing or lying on the ground or from a certain height above the ground, in a trailer.
