Abstract

The machine empties grain from a vertical cylindrical silo, using a revolving helical screw (8) which pivots about the vertical silo axis to sweep the floor. A rubber wheel (68) rolling on the silo floor has rotational motion generated by the screw. Intermittent rotation is transmitted to the rubber wheel by an offset crank pin 60) and a linearly reciprocating strap (61). The one way strap motion is transmitted to an intermediate wheel (65) by an articulated (64) shoe (62) equipped with a brake block (63) and secured by a spring (67). A second articulated (71) brake block (70) applied by a second spring (74) prevents reverse rotation and strap amplitude may be regulated by a cam (75).

Description

Le Brevet principal décrit un dispositif de vidange intégrale d'un silo cylindrique a axe vertical, pour grain de récolte, au moyen d'une vis hélicoidale conique rotative a pas progressif solidaire d'un profil formant raclette, disposée radialement sur le plancher de la cellule et susceptible d'être entraînée en rotation autour de l'axe du silo par une roue caoutchoutée d'axe vertical roulant sur la surface interne du silo, ou par une roue d'axe horizontal roulant sur le plancher. Dans les deux cas la roue caoutchoutée est entrainée en rotation autour de son axe par l'intermédiaire de la vis hé2icodale autour de son propre axe avec interposition d'un réducteur de vitesse ou d'un systeme roue à rocher ensemble pignons et chaine. The main patent describes an integral emptying device of a cylindrical silo with vertical axis, for crop grain, by means of a conical rotary helical screw with progressive pitch secured to a squeegee profile, arranged radially on the floor of the cell and capable of being rotated about the axis of the silo by a rubberized wheel with a vertical axis rolling on the internal surface of the silo, or by a wheel with a horizontal axis rolling on the floor. In both cases the rubberized wheel is rotated around its axis by means of the helical screw around its own axis with the interposition of a speed reducer or a rock wheel system with pinions and chain.

La présente addition a pour objet une variante du dispositif d'avance de la vis de balayage et d'entrainement de la roue caoutchoutée d'axe horizontal roulant sur le plancher, objet du certificat d'addition n" 76 06406 en date du 5 Mars 1976. The present addition relates to a variant of the device for advancing the scanning screw and driving the rubberized wheel with a horizontal axis rolling on the floor, subject of addition certificate No. 76 06406 dated March 5 1976.

Ce dispositif consiste a prévoir a l'extrémité de la vis hélicofdale de balayage du plancher du silo un maneton excentré commandant le pied d'une bielle logée dans un carter dont l'extrémité porte un sabot équipé d'un patin monté sur unearticu lation élastique et engagé dans la gorge dsune roue d'axe horizontal sur lequel est montée la roue d'entraînement sur le plancher. Le mouvement circulaire uniforme de la vis de balayage est ainsi transformé en mouvement rectiligne alternatif de la bielle d'entrainement pas a pas des roues.  This device consists in providing at the end of the helical screw for sweeping the floor of the silo an eccentric crank pin controlling the foot of a connecting rod housed in a casing, the end of which carries a shoe fitted with a shoe mounted on an elastic strap. and engaged in the groove of a wheel with a horizontal axis on which the drive wheel is mounted on the floor. The uniform circular movement of the scanning screw is thus transformed into a reciprocating rectilinear movement of the stepping drive rod of the wheels.

D'autres caractéristiques de ce dispositif seront décrites ci-après en référence a un exemple de réalisation et en référence au dessin annexé. Other characteristics of this device will be described below with reference to an exemplary embodiment and with reference to the attached drawing.

La figure 11 est une vue en perspective de l'extr6- mité de la vis hélicoldale et de son système d'entraînement. Figure 11 is a perspective view of the end of the helical screw and its drive system.

La figure 12 est une vue en coupe verticale de ce meme système d'entraînement. Figure 12 is a vertical sectional view of the same drive system.

L'extrémité de l'axe de la vis hélicoldale radiale 8, débouchant dans un carter 40, comporte un maneton excentré 60 qui permet de transformer le mouvement circulaire uniforme en mouvement rectiligne alternatif par l'intermédiaire de la bielle 61. A l'extrémité de celle-ci, un sabot 62 équipé d'un patin 63 de section trapézoîdale, est monté sur une articulation élastique 64 bloquée en position de déformation angulaire permanente de façon que celle-ci provoque un couple de rappel élastique et assure de ce fait une pression constante à l'attaque dans la gorge trapézoidale d'une roue en fonte 65 calée sur un axe 66. The end of the axis of the radial helical screw 8, opening into a casing 40, comprises an eccentric crank pin 60 which makes it possible to transform the uniform circular movement into reciprocating rectilinear movement by means of the connecting rod 61. At the end thereof, a shoe 62 equipped with a shoe 63 of trapezoidal section, is mounted on an elastic articulation 64 locked in the position of permanent angular deformation so that the latter causes an elastic return torque and therefore ensures a constant attack pressure in the trapezoidal groove of a cast iron wheel 65 fixed on an axle 66.

Dans son mouvement rectiligne alternatif la bielle tenue en applique par un ressort de rappel 67 entraîne pas a pas la roue en rotation par l'intermédiaire du patin 63 qui adhère par coincement dans la gorge de celle-ci. In its reciprocating rectilinear movement, the connecting rod held in place by a return spring 67 drives the rotating wheel step by step by means of the shoe 63 which adheres by jamming in the groove thereof.

La rotation de la roue caoutchoutée 68 qui est ca lée sur le même axe que la roue en fonte et qui roule sur le plancher du silo est donc assurée, et par conséquent, celle de la vis hélicoidale de balayage 8 qui est nécessaire pour assurer la vidange intégrale de la cellule. The rotation of the rubberized wheel 68 which is cast on the same axis as the cast iron wheel and which rolls on the floor of the silo is therefore ensured, and therefore that of the helical scanning screw 8 which is necessary to ensure the complete emptying of the cell.

Un sabot 69, équipé d'un patin 70 bloqué sur une ar articulation élastique 71 de conception identique a celle décrite précédeminent est monté sur un bras de couple 72 maintenu en position de contact permanent avec la roue 65 par i 'intermédiai- re d'une autre articulation élastique 73 et d'un ressort de rappel 74 empêche 1 retour en arrière de la roue 65 par coincement du patin 69 dans la gorge trapézoidale de celle-ci et par con séquentcelui de la roue caoutchoutée -68 et de la vis hélicoldale de balayage autour de l'axe vertical du silo. A shoe 69, fitted with a shoe 70 blocked on an elastic articulation ar of design identical to that described above, is mounted on a torque arm 72 held in position of permanent contact with the wheel 65 by means of the another elastic joint 73 and a return spring 74 prevents 1 backward movement of the wheel 65 by jamming of the shoe 69 in the trapezoidal groove thereof and by consequence of that of the rubberized wheel -68 and of the helical screw sweep around the vertical axis of the silo.

Une came 75 permet de réduire a volonté le déplacement angulaire de la bielle 61 et donc de diminuer l'angle d'at taque de celle-ci par rapport a la roue 65. A cam 75 makes it possible to reduce the angular displacement of the connecting rod 61 at will and therefore to reduce the angle of attack of the latter relative to the wheel 65.

De ce fait l'amplitude du sabot varie et l'avance pas a pas aussi, Ce système fait office de variateur de vitesse. Therefore the amplitude of the shoe varies and the advance step by step also. This system acts as a speed variator.

Il peut être étendu a tout système de réduction et de variation de vitesse pas a pas par la transformation d'un mouvement circulaire uniforme en mouvement rectiligne alternatif et par l'entraînement pas à pas d'une roue autour d'un axe.  It can be extended to any step reduction and speed variation system by transforming a uniform circular movement into an alternating rectilinear movement and by stepping a wheel around an axis.
