The invention provides an improvement to the feed path for conventional belt round balers in the agricultural industry, and reduces the jamming of baling material in the feed gap of the baler. In a commonly known round baler the baling material enters the bale forming chamber through a feed gap defined by an upper roller and rotating away from the bale forming chamber, and a lower roller and rotating towards the bale forming chamber. As the upper roller is moving counter to the flow of baling material into the bale forming chamber, baling material which contacts them is retarded, and tends to form a ball of material which can plug the feed gap. The present invention provides a plate covering the upper roller which plate deflects the baling material into the feed gap and prevents the baling material from contacting the upper roller. The invention could be provided as an integral flange manufactured in new balers, or could be produced as a mountable plate for retrofitting of existing equipment.
L'invention fournit une amélioration au trajet d'alimentation de presses à balle ronde classiques dans l'industrie agricole, et réduit les risques de blocage de matériau à mettre en balles dans l'espace d'alimentation de la presse à balle. Dans une presse à balle courante, le matériau à mettre en balles entre dans la chambre de formation de balles à travers un espace d'alimentation défini par un rouleau supérieur et tournant en s'éloignant de la chambre de formation de balles, et un rouleau inférieur et tournant en direction de la chambre de formation de balles. Lorsque le rouleau supérieur se déplace à contre-courant du flux de matériau à mettre en balles dans la chambre de formation de balles, le matériau à mettre en balles qui entre en contact avec eux est retardé, et tend à former une boule de matériau qui peut boucher l'espace d'alimentation. La présente invention fournit une plaque couvrant le rouleau supérieur, plaque qui dévie le matériau à mettre en balles dans l'espace d'alimentation et empêche le matériau à mettre en balles d'entrer en contact avec le rouleau supérieur. L'invention peut être fournie sous forme de bride intégrée fabriquée dans de nouvelles presses à balle, ou peut être produite sous forme de plaque montable pour la modernisation des équipements existants.
