DESCRIPTION

Mouthpiece for granules with automatic closure and agitation system Object of the invention

The object of the present invention is a mouthpiece for channeling granulated products with an automatic closing and stirring system to avoid lumps, so that any accumulation of product can be broken and avoid embossing without the need for manual intervention of No operator

The field of application of the invention is framed within the logistic sector and more specifically in the field of apparatus, machines and devices for loading and unloading systems of goods, particularly solid granulated merchandise from maritime containers to silos.

State of the art

As it is known, today, to facilitate the transport in containers and the unloading in silos of solid granulated goods, with different thicknesses of grain, some containers known as “liner” are used that normally cover the entire capacity of a container .

The liner is a large bag with certain benefits for filling, closing, securing and opening for emptying that is introduced into the shipping containers.

Once transported, for unloading in the final container, the granules packed in the aforementioned container liner, precipitate by gravity, tilting the trailer on which the container goes, towards the mouth of a rotating valve that, with the contribution of Pressurized air, manages to propel it through tubes towards said container, normally silos.

The mouthpiece to which the market falls has the purpose of channeling the granulated product inside the rotary valve and, at the same time, has a system to break some small lump or caking that, currently, is manual, like the broth gate of the product.

GB-A-3 223 290 discloses a mouthpiece for channeling granulated products according to the preamble of claim 1.

The problem is that said manual system implies that it is the driver or operator who is doing the unloading that is manipulating the closing lever, while the container continues to swing on the trailer, with the entire unloading system in full operation.

This need, obviously, implies a risk situation for the operator who is carrying out the discharge, being an object of the present invention the development of a new type of mouthpiece that meets the same purpose as those currently existing, but where the agitation of the product is carried out automatically, so that while the discharge is taking place, the operator in charge does not have to be manually manipulating the mouth and can wait for the discharge to be completed away from the tipping container, eliminating any risk of security.

Description of the invention

In order to solve the technical problems reflected in the state of the art, the mouthpiece for the channeling of granulated products with automatic closing and agitation system, object of the present invention, is as indicated in the attached claim 1.

In a first embodiment of the invention, the connection mechanism comprises a rack connected to the pneumatic drive to which a pinion is attached, whose axis, in turn, joins the lower end of the blade inside the hopper.

In this first practical embodiment, the closing lid is linked to a second pneumatic drive and configured to regulate the flow in the hopper. Both the first pneumatic drive and the second pneumatic cylinder are compact double-acting and 100 mm diameter cylinders.

In a second embodiment of the invention, the connection mechanism comprises a connecting rod coupled to a first shaft which, in turn, is connected with a second shaft jointly joined to the lower end of the blade located inside the hopper. In this

realization the pneumatic drive is a compact double acting cylinder with a diameter of 100 mm, connected with a bistable valve.

In both practical embodiments the pneumatic drive and the connection mechanism are housed in a housing adjacent to the hopper. In addition, the hopper is attached to the liner outlet, since both have the same shape and dimensions, by means of a plurality of side anchors configured to prevent access from the top and bottom during the operation of the hopper.

Throughout the description and the claims the word "comprises" and its variants are not intended to exclude other technical characteristics, additives, components or steps. For those skilled in the art, other objects, advantages and characteristics of the invention will be derived partly from the description and partly from the practice of the invention. The following examples and drawings are provided by way of illustration, and are not intended to restrict the present invention defined in the appended claims.

Exhibition of a detailed mode of realization of the invention

A first example of practical embodiment of the present invention is shown in Figures 1 to 3. Thus, as observed in said figures 1 to 3, the mouthpiece (1) in question is configured from a hopper (2) that is coupled, at its top to the outlet of the liner to which it is intended, and from the bottom, through an outlet pipe (3) to the emptying vessel. The liner is not represented in figures 1 to 3.

The hopper (2) has the particularity of having, internally, with a mobile shovel (4) that is configured to hit the granulated product that passes through the hopper (2) in the gravity emptying operations of the liner, in order to break the lumps or lumps that may be formed and for whose operation said blade (4) is linked to a pneumatic mechanism housed in a housing (5) located adjacent to the hopper (2).

Said mechanism comprises, at least, a double acting cylinder (6), with two limit switches and which is fed by a valve (7), preferably bistable. This cylinder (6) moves a rack (8) coupled to a pinion (9) whose shaft (10), in turn, joins the lower end of the blade (4) inside the hopper (2).

In parallel, the hopper (2) has a lid (11) that closes said hopper (2) inferiorly to give way or not to the product. This cover (11) is associated with a second cylinder (13) of the pneumatic mechanism located laterally, and with the same characteristics as the first cylinder (6), said second cylinder (13) being associated, by means of a connecting rod (14) to a support in the form of a second axis on which said cover (11) tilts, so that the gradual actuation of said cylinder (13) causes the graduated opening of the cover (11) to give way to more or less product flow and be able to close it automatically.

Finally, it should be noted that the hopper (2) is fixed in the liner by means of a plurality of lateral anchors (12) provided for this purpose, the hopper (2) being arranged so that it is not accessible in operation from its upper or lower part.

A second example of practical realization of the invention is shown in Figures 4 to 6, where the mouth (1) for granules with automatic closure and agitation system is configured from a hopper (2) suitable for coupling, meanwhile upper, at the exit of the 5 liner to which it is intended, and from the bottom, through an outlet tube (3) to the container of

emptying The liner is not represented in figures 4 to 6.

The hopper (2) has the particularity of having, internally, with a mobile shovel (4) that is configured to hit the granulated product that passes through the hopper (2) in the 10 gravity emptying operations of the liner, with the object of breaking the lumps or lumps that may be formed and for whose operation said blade (4) is linked to a mechanism housed in a housing (5) located adjacent to the hopper (2).

Said mechanism comprises, at least, a double-acting cylinder (6), with two endings of 15 stroke and which is fed by a valve (7), preferably bistable. This

cylinder (6) moves a connecting rod (8 ’) coupled to a first axis (9’) connected to a second axis

(10 ’) which, in turn, joins the lower end of the blade (4) in the interior of the hopper (2), forming a crank-crank mechanism pneumatically actuated by the cylinder (6).

In parallel, the hopper (2) has a closing lid (11) configured to give way to the product.

Finally, it should be noted that the hopper (2) is fixed in the liner by means of a plurality of 25 lateral anchors (12) provided for this purpose, being arranged so that it is not accessible in operation by its upper part or its part lower.
