Le conditionnement doseur selon la présente invention est constitué de trois éléments : un corps (1) creux en polypropylène injecté, un verseur (2) en polypropylène injecté, un capot (3) en une matière plastique quelconque; le corps creux et le verseur étant capables d'être liés l'un à l'autre par emboîtement en produisant une fermeture étanche, ce conditionnement a une durée de vie prolongée par rapport aux sachets en papier.

Ce semoir comporte en combinaison : une trémie (3) contenant les graines, un organe distributeur (10, 19) placé en aval de cette trémie, un organe régulateur (14) déterminant le débit des graines de la trémie à l'organe distributeur et un petit moteur électrique inclus dans un carter (1) auquel il transmet des vibrations et sur lequel est montée la trémie précitée.

The present invention refers to a self-propelled sowing machine (1), steered by a user standing on the ground, comprising a frame (2) to which are connected at least one front wheel (3A) and at least one rear wheel (3B) that allow its movement in the direction of travel (A) controlled through manoeuvring means (5), and a pneumatic precision seeding device (50) mounted on the frame (2) and comprising a rotating perforated disk interposed between a seed container (11) and a case (12) defining a suction chamber, and cooperating on one hand with an air suction device (20) and on the other with a selector suitable to select individual seeds that are released into at least one discharge chute (8) for laying the seeds on the ground. The sowing machine includes a single drive means (4) fastened on said frame (2) that transfers the movement to said at least one front wheel (3A) through a first transmission unit (14) and to the air suction device (20) through a second transmission unit (24) separate from said first transmission unit (14).

Methods and apparatus are provided for dispensing chemical material, and in particular, granular, agricultural material, from a moving device driven over terrain to be treated with the material. A metering system for dispersing the material includes on apertured metering disk (70) positioned above a rotatable impeller (114). The apertured disk meters material from a product container (6), by gravity feed, onto the impeller (114) below at a rate proportional to the linear speed at which the apparatus is driven to dispense material at a uniform density over the terrain. The metering disk (70) is a component of a product container (6) which is removably mounted to the device. The impeller (114) rotates at a constant speed to disperse the deposited material at a uniform distance from the apparatus, and the position on which the material is deposited on the impeller (114) is adjustable. A clutch permits the user to discontinue dispensing material from the device at the selection of the user, and automatically discontinues dispensing of material when the apparatus is driven in a reverse direction.
