Description

SCOPE OF THE INVENTION

The main object of this utility model is a NEW ASSEMBLY ARRANGEMENT OF THE CRADLE THAT LIFTS THE BAG INTO THE BAGGING POSITION TO ARRANGE THE SAME ON THE GRAIN BAGGER TUNNEL, so that the need of manually moving the folding bag from the cradle that lifted the same up to the top tunnel of the grain bagger, is thoroughly removed, to arrange it supported over the external face thereof, so that it hangs forming a tubular body of substantially circumferential section.

Specifically, the present utility model encompasses a new assembly arrangement that takes the above mentioned cradle that lifts and places the bag into the bagging position, which folding bag is received, lifted and then positioned over the curved tunnel of the grain bagger being ready to be used.

As it is already known, the referenced cradle that receives the folding bag to be positioned over the tunnel, is kept by a lifting equipment basically formed by two pairs of articulated side arms that define the systems of distorting parallelogram, which turn round on an angular basis so as to lift the same up to arrange it in a coplanar way and adjacent to the machine tunnel.

Then, the user has to proceed to move the holding and lifting bag, by manually displacing it from the cradle to the tunnel, so as to arrange it supported over its curve surface, so that it keeps hanging and taking the above mentioned tubular shape.

This new assembly which the present utility model refers to allows the same cradle supported by the pairs of articulated arms, to be totally arranged over the tunnel, removing the above mentioned need to handle the bag, thus avoiding all the inconvenient this may cause.

It deals about a new arrangement obtained on known objects that renders a better use of the function to which they are intended. Accordingly, such new arrangement may be protected under the concept of Utility Model set forth by the Invention Patents Act under the articles 53 to 58.

PREVIOUS ART

As it is already known the grain baggers of dry grains in bags hold a fixed structural tunnel that defines a curved surface of semi-circumferential section, which diameter is equivalent to the one the bag will have when filled with grains.

The tunnel so made acts as a receiving rigid support of the folding bag, designed to position the bag so that it may go unfolding as it is filled with grains being discharged thereon.

Once the folding bag is positioned over the tunnel, the first unfolding is carried out to make up an end sealing that is carried out before starting the grain feeding load

As it is already known, then it follows the entering of bulk grains mass that are received by the top hopper so that, as the internal pressure into the hopper increases, the bag is progressively unfolding as a consequence of the displacement, in an opposite sense of the load, that is being made by the machine, remaining in suitable conditions to continue receiving grains on a constant basis.

It remains clear that to carry out the whole load and feeding process explained in the foregoing paragraphs, it comes to be extremely important that the folding bag being supported by the surface that define the top external face of the tunnel.

The problem appears when the assembling of the bag should be carried out over the tunnel as, the cradle only shows the bag lifted and adjacent to the tunnel body. The user has to manually dissemble the bag from the cradle and move it to the position over the tunnel.

This manual loading, moving and positioning, is extremely uncomfortable to be made manually, above all due to the proper weight of the folding bag, being necessary, in most cases, the cooperation of various people.

Presently, these cradles comprise a light tubular and curved structure, comprised of a pair of elongated loading skids with a curved shape which curvature has a diameter equal or similar to the one that defines the tunnel body.

Such loading skids with a curved shape, are kept bonded and parallel by a group of members that extend between both to confer a structural rigidity to the cradle, being the separation established between them which determines the width of the cradle structure.

This constitutive structure of a cradle is mounted on the top free end of a lifting equipment that comprises of both pairs of arms extending in a rotating way from a vertical fixed supporting plate that the machine has below the tunnel, making up a system of distorting parallelogram.

With the rotation of the mentioned rotating arms, the cradle progressively lifts, up to being arranged adjacent to the tunnel.

However it is worthwhile mentioning that the arrangement of these pairs of rotating arms in the above mentioned fixed plate of the grain bagger and, above all the location of the rotating point where the assembly in the structure that constitutes the cradle body is produced, prevents said cradle from being arranged above the tunnel.

It just reaches to locate adjacent thereto, requiring the user to make the referred manual work to draw the bag from the cradle and move it so as to arrange it over the tunnel.

DESCRIPTION OF THE INVENTION

The new assembly arrangement of the cradle of the folding bag, has specifically been created so that it is duly positioned over the grain bagger tunnel, directly, without being necessary any manual moving.

Indeed, the light tubular structure that gives a curved shape to the above explained cradle keeps unalterable, being always the same; neither altering nor disappearing the above mentioned pairs of arms that extend in a rotating way from the supporting fixed plate, however, with the assembly established according to the present invention, the cradle may be arranged directly over the top and external surface of the tunnel.

The novelty being incorporated and encompassed by the register of this utility model is based on the following two assembly conditions, namely:

• • 1. The above mentioned pairs of rotating arms that constitute the above mentioned lifting equipment, extend towards outside, in the longitudinal direction of the machine, from a respective fixed and lower elongated plate that, mounted on the machine structure extends towards outside beyond the space that defines the tunnel, so that the respective articulations of lower pivot of said rotating arms, are arranged lower outside the space that determines the tunnel;
  • 2. Meanwhile the same pairs of rotating arms of the lifting equipment extend up to the respective points of upper articulated bonding that are located in correspondence with the curved member further away from the machine that has the above mentioned cradle.

As from these novel assembly conditions, when the cradle, holding the folding bag is lifted, both pairs of rotating arms may turn around up to position the bag in an upper level, above the height level that constitute the tunnel, after which nothing prevents both pairs of arms from continuing turning around as regards their rotating points, in which case, the same cradle turns back a short path and decreases its height till being arranged over the tunnel.

In order to command and control the turning movement made by the above mentioned pairs of rotating arms, it is possible to use a little winch of manual driving or, to use an hydraulic engine associated thereto, which pulling cable before getting associated to the cradle, will pass through a free pulley mounted fixed to an upper point, through which it is possible to lift the cradle allowing the same, besides the ascendant displacements produced by the pairs of supporting rotating arms, make a first displacement forwards, and then a second displacement backwards, up to being located over the tunnel.

The cradle without holding the folding bag may also be arranged over the tunnel during the machine movements.

DETAILED DESCRIPTION OF A PREFERRED EXAMPLE

As it can be appreciated in FIG. 1, the present utility model refers to a new assembly arrangement of the cradle (P) that lifts the bagging (not shown), that allows to arrange the bag over the top face (2) of the tunnel (C) that is possessed by the grain bagger (B).

Specifically, this figure schematically represents a grain bagger (B) of the type that holds a tunnel (C) that has a curved roof (2) that extends with lateral walls to give a receiving seat to the folding bag.

Below the feeding hopper (V) there stands a communication mouth wherein a feed auger (3) that drives the grains towards the interior of the bag being positioned turning round the tunnel, which goes unfolding as the internal pressure produced by said grains mass generates the displacement of the machine in the opposite sense of the load.

The machine is completed with a rolling train (R), a drawing pipe (T) with its corresponding engagement (G), the hopper (V), and a gimbled transmission (4) where the actuator for the referred feed auger takes the command from (3), as well as, eventually, to the winch (not shown) that produces the lifting of the lifting equipment (S) that holds such cradle (P).

It is appreciated that this cradle (P) belongs to the type that is made by a pair of curved, equal and parallel loading skids, one proximal (5) and the other one distal (6), which are kept joined by a group of members (7), with a separating distance sufficiently wide as to be able to suitably receive the folding bag.

As it is specially shown by FIG. 2, the new assembly arrangement of the cradle (P) which the present utility model refers to, is defined with the new lifting equipment (S) that, in this case, is made from a pair of elongated planar plates (8) arranged in vertical parallel plans to the longitudinal direction of the machine, which extend from a substantially vertical wall (9) located in a back plan, within the space enclosing the tunnel (C).

Specifically, FIG. 2 shows one of said pair of elongated fixed plates (8), being possible to observe that the same extends towards outside clearly protruding of the edge line of said tunnel (C), and following a descendant right line.

Each elongated plate (8), in correspondence with its free end, defines a peripheral side (10) where the lower rotating points (11) and (12) of the pairs of rotating arms are formed which, together with said elongated plates constitute the referred lifting equipment (S).

Said rotating arms, identified with the reference numerals (13), (14), (15) and (16) extend to associate with the cradle (P) in the upper rotating points (17), (18), (19) and (20) that are formed in the rigid triangular flat plates (21) and (22) (shown in FIG. 1) supportive to the cradle.

As it is specially shown in the detail that represents the FIG. 3., the novelty characterizing the assembly that encompasses the present utility model, is based on the fact that said rigid flat plates (21) and (22) are mounted in correspondence with the distal curved member (6) that constitutes the cradle body, the cradle extends projecting from.

As it is specially shown in FIG. 6, this projecting of the cradle body, together with the new location of the lower rotating points (11/11′) and (12/12′) of the pairs of the rotating arms ((13/14) and (15/16) of the lifting equipment (S), is the one that allows to arrange the cradle over the curved roof (2) of the tunnel (C).

Under the mentioned conditions, FIGS. 4, 5 and 6 respectively represent the different positions that the cradle is taking as it is lifted up to be positioned over the tunnel.

FIG. 4 represents the cradle in the lower position that is taken to receive the folding bag. It is appreciated that, in this position, said cradle (P) is arranged in the further away position from the tunnel keeping free spaces so that users may work comfortably in the bag placement.

FIG. 5 shows the cradle in an intermediate lifting position of its ascendant path. It is appreciated that the cradle body (P) by keeping its horizontal arrangement, is nearer to the tunnel, in this case the rotating arms have made an ascendant angular movement.

Finally, FIG. 6 shows the cradle duly positioned over the tunnel which is the definitive position that takes to keep the folding bag in the use arrangement. The cradle (P) stays superimposed following the same curvature degree than the tunnel, remaining as a light structure inserted between the bag and the tunnel.
