DESCRIPTION

Holder with retention system and cutting of tied elements.

Technical object of the invention

The present invention relates to a machine capable of retaining and cutting the bundle elements of fiber bales (straw, hay, alfalfa, corn cañote ...) or industrial products (cardboard, paper, plastics, rags ... ) so that the operator without lowering the machine can carry out the operation in an optimal way, managing to reduce the efforts made in the task and managing to reduce the operating times and consequently the costs.

Sector of the technique to which the invention relates

The invention presented affects the Sectors of Current Needs of Life and Fixed Construction in its sections of Rural Activities and Implements for Industrial Machinery affecting the industry related to the project and manufacture of accessories for the loading and handling of bales or bales of agricultural or industrial products.

Background of the invention

Bale collection, transport and handling operations are common in agricultural or industrial work. The mechanization of this type of operations has been the subject of several inventions registered in the Patent Office. As an example we can cite the following:

ES-0329877 A1 Hydraulic bale loader

ES-0395197 A1 Bale loader mechanism

ES-1034219 U Device for loading and stacking bales on trailer ES-1004426U Bale loader trailer

ES-2034865 A1 Cylindrical bale loader trailer

ES-2039134 A1 Improved bale loader trailer ES-2241398 A1 Bale unifying compactor

ES-2335952 A1 Agricultural bullet collector

From its reading it follows that, practically in all cases, the cited inventions describe solutions for the loading of bales on the vehicle itself or on a tow vehicle for subsequent transfer to warehouse or any other place. When you want to use a bale, you must load it with the shovel in the warehouse, take it to the destination, unload it, flip it when necessary, cut the ties to remove them and distribute the product.

It is also known a procedure for handling bales in which the operator / s is the one who has to deposit the package on the belt, flip it to achieve its placement in the position required for cutting the tied elements, manually cut and extract the same (task for which another additional operator is normally needed). Once the package or bale is ready without any rope and still on the belt, it is necessary to use a loader to load the product in bulk from the ground and place it in the required place.

It is easily understood that the system described above requires a lot of time and additional labor with the consequent increase in the cost of the operation, which, in conclusion, requires the removal of the ties so that they do not intermingle with the main material.

In view of this background, the inventor presents in this document an implement for conventional machinery that allows handling bales of agricultural or industrial products, such as alfalfa, straw, corn cane, hay, cardboard, paper, plastic, rags, etc. ., developing a procedure that allows carrying out the operation with a single operator and a single device, such as the one described below and whose essential characteristics are set out in the following paragraphs, the inventor not knowing the existence of a background that satisfactorily resolved The problematic exposed.

Summary Description of the Invention

As indicated above, the object of the invention is a device that, as an implement of any usual loading machine, allows the bales of agricultural or industrial products to be manipulated, optimizing the operation. The process includes the following phases:

- Loading and transporting a bale or package, still tied, allowing the movement and location of the bale or package on the desired container or place, for unloading, after cutting the ties, without using a loader or any other element arranged for loading and / or transport.

- Retention / clamping and cutting of the bale or bundle tying elements avoiding the lowering of the machine operator and the manipulation of said tying elements.

- Transport and unloading of the tied elements in the selected place with the same machine and operator.

For this purpose, an implement that can be coupled to shovels, tractors, wheelbarrows, bulls, etc., is designed, consisting of the following main elements:

- Frame

- Quick hitch means

- Lower fasteners or side capture Fixed wedge-shaped bar

- Double mobile bar

- First hydraulic retention cylinder acting on the double mobile bar - Cutting device

- Second hydraulic cylinder acting on the cutting device

- Other accessories

Description of a preferred embodiment

Bale holder with retention and cutting system for tying elements consisting of an implement that, coupled to a tractor, shovel, wheelbarrow or similar machine, allows not only the handling and transport of fiber bales (straw, hay, alfalfa, cañote de corn ...) or industrial products (cardboard, paper, plastics, rags ...) but also the retention and cutting of its binding elements so that the operator performs such operations without lowering the machine. In a preferred embodiment by its inventor, it comprises a frame (1) with quick engagement plates (2), for coupling on the main machine, with several fasteners (3), a fixed bar (4) with a pointed tip. wedge (4.1), a double movable bar (5) that can rotate on the joint A (5.1), located at the end of the fixed bar (4) closest to the frame (1), actuated by means of a hydraulic cylinder of retention (6). It also has a guillotine cutting bar (7) rotating on the joint B (7.1) and a hydraulic cutting cylinder (8) as reflected in (Fig. 1)

The double mobile bar (5) is composed of two bars of preferably rectangular section, placed in parallel, leaving each other an opening that will vary depending on the thickness of the ties (10) in such a way as to allow the clamping of said ties (10) Without breaking them.

As for the cutting bar (7) guillotine type, it can rotate on its joint B (7.1), operated by the hydraulic cutting cylinder (8), so that when this reaches its maximum elongation is approximately the same height as the fixed bar (4) located at the opposite end of the frame (1).

This arrangement of the aforementioned elements allows the capture of a bale (9) by introducing the fixed bar (4) below the ties (10) with the guarantee that the bale (9) is supported, at the last end, by the elements clamping (3) (Figs. 1 and 2). The fixed bar (4) is introduced into the bale (9), puncturing and piercing its product, slightly raising the ties (10), without being damaged, when the wedge tip (4.1) is chamfered or rounded.

Once the position represented in (Fig. 2) is reached, the operator orders the extension of the hydraulic retention cylinder (6) so that the clamping of the ties (10) between the fixed bar (4) and the double mobile bar ( 5) according to detail represented schematically in (Fig. 5).

Once the ties (10) have been pinched, they are cut by ordering the operation of the hydraulic cutting cylinder (8) so that the bale (9) can be unloaded at the desired location.

Once the bale has been unloaded (9), the ties (10) are carried, which still remain pinched, to the place of provisional collection where the hydraulic cylinder (6) is held to undo the clamp effect and are released for subsequent transport to recycling.

It is important to emphasize that all these operations are carried out without the operator getting off the machine with the consequent saving and optimization of the process.

In (Fig. 3) the scheme of the hydraulic circuit of the device can be observed, for the case in which the device is operated hydraulically with a single control which, in addition to the hydraulic retention cylinder (6) and the hydraulic cutting cylinder ( 8), includes a flow regulating valve (11) that allows the control of the cylinders, a pressure limiting valve (12) to avoid overpressures and a double non-return valve (13) so that pressure losses do not occur and that, consequently, the ties (10) remain retained by the machine during the whole process that, started with the clamping, continues with the cutting and the subsequent transport until its release at the place of collection.

In optional solutions the hydraulic circuit is replaced by a pneumatic or electrical installation that responds to the same general program to ensure the moment when the clamping begins and the fastening of the ties (10) during the following cutting and transport process.

With regard to the clamping mechanism, in anticipation of the different types of existing ties (10) and to improve its retention, the option represented in (Fig. 6) is contemplated where the double mobile bar (5) is internally equipped with an elastic material (15) so that the normal capture of the ties (10) by lateral pressure is increased with a greater force that imprisons them on the fixed bar (4). As appropriate, fasteners (3) are placed in the form of cylindrical or conical skewers, wheelbarrow-type shovels (14) or lateral capture pliers.

The inventor also conceives an alternative solution, schematized in (Fig. 7), for cutting the ties (10) in which the guillotine type cutter bar (7) is replaced by a shear type cutter bar (7.2 ), adding another bar similar to the fixed bar (4) so that the set works like scissors.

Finally we can see in (Fig. 8) the versatility of the device of the invention with which cylindrical bales (9.1) can also be manipulated.

It is not considered necessary to make the content of this description more extensive so that a person skilled in the art can understand the scope and the advantages derived from the invention, as well as develop and implement the object thereof. However, it should be understood that the invention has been described according to a preferred embodiment thereof, so it may be susceptible to modifications without affecting or implying any alteration of the basis of said invention. That is to say, the terms in which this preferred description of the invention has been exposed should always be taken in a broad and non-limiting manner.
