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 pneumatic single-grain seeder having a plurality of seed meters (1) for accommodating isolating devices (3), which are rotatably arranged and exposed to a pressure difference between the interior (21) of the isolating devices and the exterior (22) of the isolating devices. A plurality of holes (17-20) used to take up seeds is arranged in the device (3). The isolating device (3) is formed by a pair of isolating plates (4, 5) connected to each other at the outer edge (38, 39) of the isolating plates, which isolating plates are arranged at an offset to each other in a tangential direction in order to produce a spread seed row and are associated with separate outlets (23, 24) for leading away the seeds from the seed meter (1) in the direction of a seed coulter.

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 equally spaced in the ground. The seed meters play a special role here, which a...
