Problems solved by technology

[0003] Conversely, when the seeds are irregularly shaped or do not fit, the disc cannot extract the seeds from the reservoir through the grooves, or the seeds enter in pairs, which produces more missing seeds and / or double seeds
Therefore, the accuracy of seeding is reduced
[0004] In addition, the presence of cavities in the grooves makes the ejection of the seeds more difficult because the seeds are too embedded in the grooves

Embodiment Construction

[0012] figure 1 An exploded perspective view of a dispensing cassette 1 according to the invention is shown. Such a distribution box 1 is generally located on a single-seed planter which distributes the seeds one by one along the sowing row. This single seed planter consists of a collapsible or non-collapsible frame carrying the sowing parts. The brackets are designed so that the spacing between the sowing parts can be changed. Each sowing part has its individual hopper or a remotely fed hopper, its distributor, its burying, rappuyage, covering and depth control mechanisms. Each sowing part is respectively installed on the support through a deformable parallelogram body, and the deformable parallelogram body can keep the sowing part parallel to the ground at any position. The function of the distributor or distribution box 1 is to take the seeds one by one from the hopper and distribute the seeds along the rows at constant intervals. The hopper constitutes the seed storage...

Abstract

The present invention relates to a distribution box (1) for a single-seed seed drill with a disc (4) provided with radial grooves (5) which are evenly spaced and open at the periphery of said disc (4), said disc (4) being mounted to rotate on a horizontal axis (4a) and separating a seed reservoir (6) from a suction device (7) so that the seeds are picked up from the reservoir (6) by said disc (4) using the stream of air at a depression and are held over at least part of their angular travel until they are expelled from a discharge opening (8). The box is notable in that each groove (5) has a suction hole (10) of a size smaller than that of the seeds that are to be distributed, said suction hole (10) opens onto a canal (11) of a width smaller than the diameter of the suction hole (10), said canal (11) is open as far as the periphery of the disc (4). The present invention also relates to a single-seed seed drill with at least one distribution box according to the invention.

Description

technical field [0001] The present invention relates to the general technical field of agricultural machinery. The invention relates to a distribution box for a single-grain planter with a distribution disk provided with radial grooves evenly spaced and opening to the periphery of the distribution disk, said distribution disk being mounted rotatably on a horizontal axis, The distribution disc separates the seed reservoir from the suction device such that the distribution disc extracts the seeds from the reservoir by the negative air flow and holds the seeds during at least a portion of the angular displacement of the seeds until the seeds are at the discharge port discharge. Background technique [0002] Such a dispensing box for single-seed seeders is described in patent application DE 10 2008 037 397 A1. The dispenser box consists of a planar rotating disk mounted on a horizontal axis. The disc picks up the seeds with an air flow that picks up and holds the seeds during...
