WO2012006755A1 - Magnetic system for precisely sowing seeds of all sizes - Google Patents

Abstract

This invention concerns a system for dispensing, selecting and transporting seeds by implanting magnetic granules attached to the surface of the seed and added during the pelletizing process before being taken one by one by the adjustable-power electromagnetic core, which can be turned off sequentially to release them and place them where required.

Description

 PRECISE SEED MAGNETIC SYSTEM FOR ALL SEEDS

 SIZE

STATE OF THE TECHNIQUE AND PROBLEMS TO BE SOLVED

At present there are several sowing systems based on the homogeneity of the seed size.

 For this, prior calibration and subsequent coating processes (pelletizing, pelleting and others) are carried out to achieve uniformity and increase them to enter the standard dimensions indicated by the manufacturers of seeders and other physical seed handling equipment.

 The Magnetic System allows to take a seed in a precise way, regulating the percentage and granulometry of the magnetic particles such as iron filings adhered to the surface of the seed, the shape and size of the electrode and the electrical intensity that is applied to the coil of the electromagnet.

 This original criterion can be applied to an infinity of traditional or new systems of dosing and selection of seeds.

The simple addition of magnetic particles to the classic seed coating processes does not add new steps or significant costs due to the economic nature of the material.

 The system adapts, among others, to a rotating one consisting of a hollow cylinder of electricity insulating material, with the electromagnets fixed inside, orienting their cores perpendicular to the surface of the cylinder.

 Said cylinder rotates laterally from a seed container container at a distance smaller than their size, with a lateral mouth and without a top cover so that by grains the grains are pressed against the cylinder,

 Activated electromagnets on the side of the container take the seeds, pick them up one at a time and release them on the opposite side when the electrical flow is programmed cut off.

 If there are seeds of different sizes in the tank and the cores of the electromagnets have a smaller diameter than that of the smallest seed, it will always be taken one by one, regardless of their size.

 It is necessary to decide the standards between each species, size, percentage and granulometry of the magnetic material, so that the standard indicates which electromagnet model and with what voltage we will calibrate the equipment.

Due to its mechanical simplicity, the system adapts to the management of large and small seeds such as traditional, forestry, horticultural and ornamental extensive crops. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

 There are two systems for handling and dosing seeds: the mechanic by gravity and the pneumatic suction. Although the pneumatic dosing system achieved more precision with less calibrated seeds, the suction as a means to hold the grains, adds complexity with lines of hoses and pumps that also suck dirt and foreign objects that obstruct and wear out the equipment for that purpose.

 Under these criteria, many industrial models were designed for different applications.

 Seed coating techniques are part of the quality protocols.

By adding a ferrous particulate during this process, we will make the material we are doing the peleting paramagnetic so that it can be handled by means of magnetism.

 This new system opens the way to a third generation of dispensers characterized by its simplicity, reliability and prepared to be associated with all precision sowing systems operated by software, controlling the sequence of action of the electromagnets that take and release the seeds as required. righ now.

 We can convert a pneumatic to magnetic dispenser in a simple way by installing coils in the disk that takes the seeds, replacing the hoses and the depressor with a power cable that excites or not to these coils by means of a sequencer.

 By not having suction holes that are clogged, we will handle small-sized seeds together by means of a needle-type electrode.

 Magnetic dispensers can also be applied to a focused and sequential fertilization if the nutrient granules have the ferrous aggregate and we convert them into paramagnetic. By varying the electric power intensity of the coil, surface and shape of the electrode, it is possible to modify the dose of the necessary fertilizer.

 Among the innumerable applications, industrial models are mentioned for planting germination trays, planting seedlings "raised" at a fair density for each species, seed collectors in fractionation plants avoiding the sweeping that makes them useless and sowing rollers with matrix of coils managed by systems equivalent to that of the luminous LED signs, to replace the seed sowing system by blasting.
