Problems solved by technology

[0012] In fact, one of the problems with these known embodiments is that since the distance between the seeds on the ground depends on the rotational speed of the distribution disc, unwanted variations in this rotational speed affect the accuracy of sowing, and due to the mechanical play that exists between the components or other reasons, the change would depend on the fact that the mechanical transmission of power becomes less precise over time
[0013] In fact, another disadvantage of these known systems is that, since they are composed of mechanical transmission parts, they are undoubtedly rather bulky

Embodiment Construction

[0039] With particular reference to these figures, a dispensing device generally designated 100, which is intended to cooperate with agricultural machinery, typically a planter, comprises an internally hollow housing 101 for defining a cavity therein. Chamber 110 for housing a dispensing disc 120 of material to be dispensed, as will be described in more detail below.

[0040] The housing 101 is defined by a first half-shell 102 and a second half-shell 103 configured to be interconnected to define a chamber 110 .

[0041] In particular, each half-shell 102 , 103 is generally defined as a concave body and is adapted to be provided with a concave surface towards the other half-shell 102 , 103 .

[0042] Furthermore, each half-shell 102, 103 comprises an outer edge flange 104 adapted to be connected and fixed to the outer edge of the other half-shell 102, 103 by suitable (per se known) fixing methods The flange 104', for example, inserts a sealing gasket.

[0043] In use, the ho...

Abstract

A material distributor device (100, 100') for a farm machine (10), comprising: a chamber (110) provided with an inlet (105) and an outlet (106) for the material to be distributed, pneumatic means forgenerating a vacuum inside the chamber (110); a rotating distributor element (120) accommodated in the chamber (110) and adapted to receive the material due to the effect of the vacuum and to transport it from the inlet (105) to the outlet (106) of the chamber (110) where the distributor device (100, 100') comprises an electric motor (100, 200') configured for rotating the rotating distributor element (120) with a rotation speed (omega) that depends on the advancement speed (v) of the farm machine (10) and on the quantity of product to be distributed.

Description

technical field [0001] The invention relates to a material distribution device for agricultural machinery, in particular for sowing seeds on the ground. Background technique [0002] As is well known, trailed or self-propelled agricultural machinery for the distribution of materials (eg, fertilizers or seeds) is common in the field of automated agriculture. [0003] A typical example of such agricultural machinery is a precision seeder, which is adapted to deposit one seed at a time with a constant distance between two seeds placed on the ground. [0004] In a precision seeder, this is used to ensure that the plants grow at the same distance from each other so that each plant has enough soil to grow. [0005] Specifically, in this field, according to the type of cultivated crops, it is pre-determined that the 2 The specific seed amount is known. [0006] A precision seeder includes a plurality of seeding units supported by a frame supported on the ground by at least one w...
