Embodiment Construction

[0034] Such asfigure 1 Shown is a seed meter 1 with a supply air inlet 66 through which a supply air flow carrying the seeds enters the seed meter 1 , more precisely into the outer space 22 of the separating plate. For example, a fan is used to supply air flow to the supply air flow inlet 66 through ductwork. The supply air flow can also be drawn into the seed meter 1 through the vacuum in the housing 16. The most important function of the housing 16 is to accommodate the separation device 3 in the form of double separation plates. Only the right side of the separation plates is marked as The separation plate of 4 can be seen in the figure. This relatively small separation device 3 can be completely accommodated in said housing 16, so that compressed air can be used particularly effectively to generate a pressure gradient. For example, four of the holes on the separation device 3 are marked 17,18,19,20. From here, the seeds are finally released through the two outlets 23, 24...

Abstract

The invention relates to a precision pneumatic seeder with a plurality of seed meters (1), said seed meter (1) comprising a separating device (3) arranged in rotation, an inner space (21) and an outer space 22 of the separating device There is a pressure difference between them. The separating device (3) has a plurality of holes (17-20) for collecting seeds. The separating device (3) is formed by a pair of separating plates (4, 5) connected to each other at respective outer edges 38, (39), the separating plates (4, 5) being offset from each other in the tangential direction, so as to Extended rows of seeds are produced and the separating plates (4,5) are distributed to respective separate outlets (23,24) for removing the seeds from the metering device (1) Discharge in the direction of the sowing coulters.

Description

technical field [0001] The invention relates to a precision pneumatic seeder, which has a plurality of seed metering devices, and the seed metering device includes a separation device arranged in rotation. There is a pressure difference between the inner space and the outer space of the separation device, and the separation device has multiple holes for collecting seeds. [0002] In addition, the present invention relates to a seed meter for a precision pneumatic seeder, said seed meter comprising a rotatably arranged separating device having a pressure difference between an inner space and an outer space of the separating device, said separating device having Multiple holes for collecting seeds. Background technique [0003] Precision pneumatic seeders, such as those known from document DE 10 2005 051 527 A1, are used in agricultural production in order to be able to sow seeds individually and at equal intervals in the ground. The seed meters play a special role here, whi...
