Description

DESCRIPTION

Seed cleaning system

TECHNICAL SECTOR

The object of this invention is a grain cleaning system, particularly aimed at cleaning seeds for bird feed.

BACKGROUND OF THE INVENTION

Thanks to grain cleaners, the seeds that remain at the bottom of the feeders are not wasted, without the need to carry out the action of blowing on them to separate them or waiting for a windy day to clean them as has been done until now. The method of use is very simple since the only action that needs to be carried out is to pour the grain into this object, so that it separates the seed from the shell into two boxes, where each one has a function.

Once a thorough investigation was carried out focusing on the products existing on the market, it was determined that most of these were manufactured in an artisanal manner and, furthermore, in many cases they did not even fulfill their function because they did not separate the shell from the seeds in the first pass, but the process had to be repeated several times, causing a loss of time.

Devices known in the state of the art [https://www.amazon.es/ARTESAL-LIMPIADOR-DE-SEMILLAS/dp/B071F8HNKS (Accessed February 26, 2022), https://www.amazon.es/nestQ-Limpiador-Semillas-Pajaros-Limpieza/dp/B08CBJTD34 (Accessed February 26, 2022), https://www.orniplus.com/maquinaria/462-limpiadora-alpiste.html (Accessed February 26, 2022), https://100ciaencasa.blogspot.com/2012/04/limpiadora-de-comida-de-pajaros.html (Accessed August 31, 2022] comprise a grain inlet that is located at the top and where the seeds are introduced with the shell to be cleaned; a system of ramps, each one placed at a different angle and of different measurements to facilitate the cleaning work; two drawers at the bottom of the box, where one collects the seeds and the other the shell, as well as an electrically powered fan whose function is to separate the shell from the clean grain in the different drawers with the air flow it expels; and a mosquito net type grid serves to make the air exit the box and not produce a draft that causes the shell, instead of going to the corresponding drawer, to remain spinning inside.

The present invention has as its object a grain cleaner taking into account the needs of the sector to which it is directed. The purpose is to make the cleaning task easier and produce a saving of time and money in grain, mainly when this product is used by breeders where consumption is higher, although its use is also suitable for people who have birds at home. Most of the known alternatives require several passes to achieve a complete cleaning.

EXPLANATION OF THE INVENTION

The system object of the present invention has a completely different internal configuration to that of the devices known in the state of the art, since it includes a main body inside which a vibrating plate is located, and with this plate and some fans is how the grain is cleaned. Another difference is that it does not include drawers for clean grain or garbage, but in this case the garbage is collected in a module connected to the main body but removable, thus allowing the garbage to be removed in the simplest way, while the clean grain is collected in a box that is placed on top of the vibrating plate. All this facilitates both the cleaning mechanism and the effectiveness of the process.

According to the above, the invention relates to a seed cleaning system characterized in that it comprises:

• A main body that houses:

oA tray (a horizontal structure limited in its perimeter by side walls) with an essentially flat, removable bottom, into which the seeds to be cleaned are poured;

or an essentially flat, mobile, vibrating structure on which the previous tray or box is placed;

or a ventilation subsystem, which generates an air flow that, combined with the movement of the structure, helps to separate the seeds from the shells, impurities or residues;

or an electrical subsystem, which allows the operation and control of the mobile components (mobile structure, ventilation subsystem); as well as

• a secondary body, which can be integrated with the main body and is removable from it, intended to accumulate the shells, impurities or residues resulting from the cleaning of the seeds;

and where:

• the walls of the removable tray that are perpendicular to the direction of the air flow form a 45-degree angle with the bottom of said tray to encourage said air flow to hit the seeds to be cleaned and separate and carry away the shells, impurities or residues; and

• the ventilation subsystem comprises at least two fans.

The term “substantially” should be construed herein as “not necessarily completely or entirely.”

In one embodiment of the system object of the invention, the fans, although ideally both operating at the same speed, have several operating modes, in order to be as energy efficient as possible, operating in the necessary mode according to the quantity of seeds that are present at that time or according to the thickness of the grain to be cleaned.

In another embodiment of the system object of the invention, to enable the movement of the essentially flat and mobile structure, it is placed on pillars that include wheels with support.

PREFERRED EMBODIMENT OF THE INVENTION

The example described below as a preferred embodiment of the invention consists of a wooden structure that includes the electrical part and all the elements for cleaning the grain, including two fans and a flat vibrating structure supported on four small wooden pillars (wheels with support have been included to enable its movement). The structure vibrates so that the shell moves and remains on top, taking advantage of the air flow generated by the fans to expel the shell towards a compartment connected to the main body but removable. The clean grains remain inside the box where they are added for cleaning, a box that is placed on the vibrating structure and vibrates with the movement of the latter, without the need for a drawer to accumulate them after cleaning.

Figures 1 and 2 show, exploded, the result of assembling all the structural elements listed and described below in the context of a preferred embodiment of the invention:

- Main body (1): Made of wood in this case, it incorporates all the electronic elements for the operation of the product. It includes the wooden slats (figures 3 and 4) that act as pillars and where the wheels (11) are screwed (figure 12) that allow the essentially flat and mobile structure (6) to move (figure 11) when vibrating. Figures 3, 4, 11 and 12 show views of the above. The front part of the main body (1) is completely defined with a T-shaped bracket (2) (figure 5) and a sliding door (3) (figure 6) on the sides of which a channel has been made that allows it to fit and slide with respect to the T-shaped bracket (2), making said front part have a mechanism to be opened easily without having to disassemble anything, allowing the extraction of the sliding door (3) when the system is to be used to couple the secondary body (5) to collect dirt. For its part, a methacrylate cover (10) (figure 14), delimited or finished on two of its edges or sides by L-shaped profiles (9) (figure 13) making the methacrylate cover (10) a sliding type, closes the upper part of this main body (1).

- Box (4) for the fans: This, which together with the fans themselves make up the ventilation subsystem, is made up of two wooden blocks where the shape of the fan was made so that it can fit in. It is also made up of a series of holes for ventilation, since under this box is the power supply that is part of the electrical subsystem and this allows it to work correctly without overheating and without any risk. There is also a board with a hole, this board separates the power supply from the essentially flat and mobile structure (6) and the removable tray (7) where the clean seeds are kept. The function of the hole that can be seen is to be able to pass the cables of the connections to this power supply. An additional board (12) allows that, once the box (4) for the fans is assembled in the main body (1), the whole assembly is perfectly closed, without direct access to the power supply housed in the lower space under the fans. Views of this box (4) for the fans are shown in figures 7 and 8.

- Secondary body (5): Intended to collect the shells, impurities or residues resulting from the cleaning of the seeds. It has two holes for ventilation and, during the cleaning process, the dirt does not return to the main body (1). Figures 15 and 16 show views of this secondary body (5).

- Seed tray (7): Used to add the seeds to be cleaned and, after the cleaning process, to accumulate the clean seeds. As can be seen in figure 4, the tray (7) has a 45 degree chamfer both at the front and at the back to facilitate the separation of the clean grain. This tray (7) is located inside the main body (1) supported on the essentially flat and mobile structure (6) with vibratory movement. In this example, the tray (7) has a handle (8) attached to it so that it can be easily removed and the clean grain can be emptied. Figures 9 and 10 show views of this box (4) for the fans.

Once the structural elements mentioned above have been assembled (figures 17 and 18), the system is complemented by the following electrical components and the corresponding connections between them: Two fans, each equipped with a propeller and a variable speed DC motor; a speed controller, common to both fans; a vibrating motor shaft, which is used to vibrate the essentially flat and mobile structure (6); a power supply for the fans and for the essentially flat and mobile structure (6); and a general on/off switch.
