Low demand solid particle conveyor for agricultural machinery. Includes a pressure source (12)A distributor of solid particle "s" (11),A base plate (10) supplies solid "s" particles to the distributor, and a permeable air passage plate (31) serves as the basis for these "s" particles. There is a higher channel (28) and a lower channel (29) within the distributor (11),Overlap vertically, separate from each other. The upper channel ends with a vertical wall (30), leans against the plate edge (31) from the bottom of the distributor, and extends by determining the channel of the second wall (10, 10a) by determining the crown or free edge (32). The second (10a) long downward wall is substantially parallel to the first (30) vertical wall, forming a vertical chamber (33). The pipe (24) at the outlet (26) defines the communication between the second section (29) and the vertical chamber (33) (26);The outlet (26) of the first (24) of the second section (29) is in line with the second outlet (35) and the second outlet (35) connected with the second (24) axis and the second vertical wall (10a).The "C" air flow into the distributor (11) is divided into two streams, one upflow and the other downflow (CI),What's on this super channel isThe flow (CI) goes to the first pipe (24). The first channel (28) has a facility (37) for recording the first flow of traffic,As the same intern through cricket. The "s" seed is driven by the "CS" over the coronation (32),They are absorbed and towed by the acceleration flow (CI) in the vertical chamber (33).Dispositivo de entrega de partículas sólidas bajo demanda, aplicada a una máquina agrícola. Incluye uno fuente de aire a presión (12), un distribuidor (11) de partículas sólidas “S”, una tolva (10) cuyo fondo alimenta partículas sólidas “S” al distribuidor y una placa (31) permeable al pasaje del aire y sobre la cual asientan dichas partículas “S”. El interior del distribuidor (11) presenta un canal superior (28) y un canal inferior (29), superp
