Description

[0001] CONSTRUCTION ARRANGEMENT APPLIED IN A CORN SEED-CONDUCTING DISC

[0002] TECHNICAL FIELD

[0003]

[0001] This utility model refers to an innovation concerning a construction arrangement introduced in a corn seed-conducting disc to be applied in the technical field of seeding machines, more specifically in seed dispensers used in planters.

[0004] STATE OF ART

[0005]

[0002] With the advent of the Agricultural Revolution and the consequent specialization of harvesting and planting processes, it became possible to manage agricultural processes in a more strategic manner in order to increase productivity and efficiency in the fields, as well as reduce the incidence of errors in the processes.

[0006]

[0003] In this sense, increasingly specialized implements were developed in order to solve specific process problems. One of said implements, which contributed greatly to increasing efficiency, particularly in planting operations, are seed-conducting discs or planting discs. These discs work to separate / individualize seeds at the time of feeding the seeds and then dose them so that the planting process occurs regularly and equidistantly.

[0007]

[0004] This procedure is important mainly to prevent the dosing of more than one seed at the same time, which can cause damage to the crop due to competition for light, water and nutrients. In addition, it is also important to reduce the existence of unseeded areas in the middle of the plantation, which generate discontinuity and prevent maximum use of the planting area. Furthermore, different crops require different spacings so that there is no competition between plants, so it is also important that the discs are specific to each crop.

[0008]

[0005] Thus, different seed conducting discs are known in the state of art, created to meet the aforementioned needs. Some examples are in the patents US 7093548B2, US 10932406B1, US 4047638 and CN 105850309B.

[0009]

[0006] Although these patents address the basic needs already mentioned, they have disadvantages, such as the use of methods involving high exit speeds and / or vacuum to retain the seed in the transport disc. The methods currently used will subsequently cause the seed to be expelled at a speed that is not suitable for its penetration in clayey soils - such as Brazilian soils - or will even cause increased rebound depending on the shape of the exit tube.

[0007] Another disadvantage of the state of art that can still be highlighted concerns the shape and depth of the receptacles, which are not suitable for the ideal allocation of the seed and, therefore, make it possible for undue displacements to occur during transport and generate difficulty in "individualizing" the aforementioned seeds, which, especially with regard to the expulsion method that uses positive pressure, creates "non-optimal" working conditions.

[0010]

[0008] Therefore, in order to resolve the difficulties encountered in the state of art, while still meeting the aforementioned agricultural needs presented, the present innovation was developed, which concerns a constructive arrangement applied to a corn seed conducting disc designed with the main purpose of providing a constructive variation in a specific shape for the type of seed, and having greater depth in order to allow the adequate individualization of the seeds in the alveoli, since they will be completely fitted and not just positioned, and subsequently their expulsion at an ideal speed for clayey soils by means of pressure variation in each alveoli as the conducting disc rotates and passes through a predetermined region of the seed dispenser, which will reduce the seed rebound rate. The innovation will be better specified in the following description.

[0011] OBJECTIVES OF THE INNOVATION

[0012]

[0009] It is worth highlighting that this patent application meets the requirements of a utility model and aims to present a seed-conducting disc having its construction arrangement adapted so that it has alveoli with a suitable shape and depth to, using positive pressure, allow the adequate insertion of corn seeds and provide a channel that allows the pressure to be equalized at a specific, predetermined point to promote their expulsion from the system at an ideal speed for penetration in clayey soils, such as Brazilian soil.

[0023] DETAILED DESCRIPTION OF THE INNOVATION

[0024] [Oil] This innovation concerns a constructive arrangement applied to a corn seedconducting disk (01) to be used in a seed dispenser (02) of seeding / planting machines.

[0025]

[0012] More specifically the innovation, in a first aspect, refers to a constructive arrangement in said disc (01), which is an internal component of a corn seed dispenser (02) and acts as an individualization, transport and dosage structure for the corn seeds admitted in the seed dispenser (02). The disc (01) essentially comprises a circular structure having projections and recesses allocated in order to provide it with functionality; more particularly, the disc (01) comprises a series of cavities, hereinafter called alveoli, distributed along its surface.

[0026]

[0013] Therefore, in its preferred configuration, the conducting disc (01) has an external diameter between 178.35 mm (7.02") and 297.25 mm (11.70"), preferably 237.80 mm (9.36"), a maximum thickness of 10 mm (0.39"), and has alveoli along the entire length of its external circumference, wherein said alveoli comprise recesses or grooves (03, 05) consisting of two different shapes that are allocated along the length of the circumference of the disc (01) in an intercalated manner, with the first groove (03) being determined by an irregular oval shape having a first axis measuring between 13.60 mm (0.55'9 and 22.80 mm (0.90"), preferably 18.22 mm (0.72"), and a second axis measuring between 10 mm (0.39") and 17 mm (0.67"), preferably 13.40 mm (0.53"). Thus, the aforementioned first groove (03) comprises a region in space that originates from the contour having the aforementioned irregular oval shape arranged on the rear face of the disc, and tapers into a cradle shape to the circumference of a through hole (04) having a diameter between 3.75 mm (0.15") and 6.25 mm (0.25"), preferably 5 mm (0.20").

[0027]

[0014] In turn, the second groove (05) is determined by an oblong shape having a length measuring between 10.50 mm (0.41") and 17.50 mm (0.69"), preferably 14 mm (0.55"), and a width measuring between 4.50 mm (0.18") and 7.50 mm (0.30"), preferably 6 mm (0,24"), wherein its length is its largest measurement. Thus, this second groove (05) is arranged in such a way as to comprise a region in space that originates from the contour having the aforementioned oblong shape on the rear face of the disc (01), and, like the first groove (03), also incorporates the shape of a cradle so that the entire region of the second groove (05) comprises a blind recess having a depth between 3 mm (0.12") and 5 mm (0.20"), preferably 4 mm (0.16"), and also in such a way that its longest side is tangent to the first groove (03).

[0028]

[0015] The disc (01), arranged on the inner side of the housing of the seed dispenser (02), also comprises a central recess (06) and a slit (07) having an internal fitting geometry for allocation and locking of a support structure (08) that is coupled to the disc (01) concentrically, in order to promote a locking between these two parts so that the rotation of the structure guides the rotation of the disc (01) by means of the slit (07) having the aforementioned fitting geometry, so that the aforementioned union promotes a synchronous rotation movement at the same speed.

[0029]

[0016] Furthermore, the aforementioned support structure (08) internally delimits a seat of a turbine (09) and, in a preferred configuration, externally engages with a motion generator that, in its preferred configuration, comprises an electric motor and is arranged on the external side of the housing of the seed dispenser (02). In a second embodiment, a motion generator of the system comprises an internal electric motor, concentric to the disc. In a third embodiment, the system does not have an electric motor, and the motion generator comprises an external mechanical drive with transmission originating from the agricultural implement on which the seed dispenser (02) is arranged.

[0030]

[0017] Furthermore, the rear face of the disc (01) delimits a chamber having positive pressure to force the corn seed into the alveoli until this alveoli reaches, through the rotary movement of the disc (01), a region having application of counter pressure that will allow the detachment of the seed.

[0031]

[0018] In an embodiment, the system comprising the disc (01) operates by means of admission of air by the turbine (09), so that this air is subsequently expelled axially and radially and fills both the upper chamber delimited by the rear face of the disc (01) and a lower chamber that will conduct the air to an injector that, at an opportune moment, will equalize the pressure in the alveolus so that the seed is released through the outlet duct of the seed dispenser (02) by gravity.

[0032]

[0019] Finally, the disc (01) also comprises a plurality of reinforcement structures (10) arranged both on its front face and on its rear face, in the internal region of the central recess (06) between said recess (06) and the slit (07) having said fitting geometry.
