10 DESCRIPTION DETAILLEE Un épandeur, montré figure 1, est essentiellement une remorque comportant une caisse 10 ouverte à l'arrière, montée sur un essieu porteur muni de roues 11 et d'un timon 12 d'attelage à un tracteur. Des moyens sont aussi prévus pour relier la remorque à une prise de force du tracteur, 15 ainsi qu'éventuellement des moyens permettant de manière générale une commande hydraulique des organes de la remorque. Un tapis de transport 20 installé de manière connue en soi au fond de la caisse. Ce tapis est entraîné par un ensemble motoréducteur, non représenté, qui lui transmet un mouvement de déplacement vers l'arrière, 20 selon la flèche Fi. Un ensemble d'épandage 3 est fixé à l'arrière de la caisse 10. Cet ensemble d'épandage 3 comporte deux hérissons 30 d'axe horizontal monté rotatifs sur un cadre placé dans le prolongement de la caisse. L'ensemble d'épandage comporte en outre deux disques rotatif placé en 25 partie inférieure du cadre et formant une table d'épandage 31. Lors de leur rotation les hérissons 30 font tomber la matière contenue dans la caisse 10 sur la table d'épandage qui projette la matière du fait de la rotation des disques 31. Le hérisson 30 selon l'invention comporte un arbre principal 301 30 destiné à être mis en rotation selon son axe. Il comporte une série de flasques 302 fixés sur l'arbre et répartis tout au long de l'arbre. Les flasques 302 sont plans, de forme générale de disque et fixés sur l'arbre principal 301 par soudure, le plan du disque formant un angle compris entre 10 et 150 avec un plan radial de l'arbre principal 301.DETAILED DESCRIPTION A spreader, shown in FIG. 1, is essentially a trailer comprising a box 10 open at the rear, mounted on a carrying axle provided with wheels 11 and a drawbar 12 to a tractor. Means are also provided for connecting the trailer to a tractor power take-off, as well as possibly means generally allowing hydraulic control of the trailer bodies. A conveyor belt 20 installed in a manner known per se at the bottom of the box. This belt is driven by a geared motor assembly, not shown, which transmits a rearward movement movement, according to the arrow Fi. A spreading unit 3 is attached to the rear of the body 10. This spreading unit 3 comprises two hedgehogs 30 of horizontal axis rotatably mounted on a frame placed in the extension of the body. The spreading assembly also comprises two rotating discs placed at the bottom of the frame and forming a spreading table 31. During their rotation, the hedgehogs 30 drop the material contained in the box 10 onto the spreading table. The hedgehog 30 according to the invention comprises a main shaft 301 30 intended to be rotated along its axis. It comprises a series of flanges 302 fixed on the shaft and distributed along the shaft. The flanges 302 are planar, generally disk-shaped and fixed to the main shaft 301 by welding, the plane of the disk forming an angle of between 10 and 150 with a radial plane of the main shaft 301.

5 Les flasques 302 ont des échancrures 3021 en périphérie 3020 de manière à former des dents 3022 faisant saillie entre les échancrures 3021. Les dents 3022 sont prolongées par des couteaux fixés de manière amovible, par exemple par boulonnage, et prolongeant les dents 3022. En fonctionnement, les hérissons 30 tournent dans le même sens, 10 montré par la flèche F2 de manière à remonter la matière en provenance de la caisse vers le haut. La matière est contenue par un écran 33 et retombe le long de hérissons 30, à l'opposé de la caisse 10, en direction de la table d'épandage 31. On constate qu'un tel hérisson 30 déchiquète proprement la matière 15 en provenance de la caisse, sans créer de concentration à l'horizontal, contrairement aux hérissons 30 en forme de vis.The flanges 302 have notches 3021 at the periphery 3020 so as to form teeth 3022 protruding between the notches 3021. The teeth 3022 are extended by knives removably attached, for example by bolting, and extending the teeth 3022. In In operation, the hedgehogs 30 turn in the same direction, 10 shown by the arrow F2 so as to raise the material coming from the box upwards. The material is contained by a screen 33 and falls along hedgehogs 30, opposite the body 10, in the direction of the spreading table 31. It can be seen that such a hedgehog shreds cleanly the material 15 coming from of the box, without creating horizontal concentration, unlike the hedgehogs 30 in the form of screws.
