CONSTRUCTIVE ARRANGEMENT IN CUTTING AND COLLECTION PLATFORM COUPLED TO THE FORAGE HARVESTER

BRIEF PRESENTATION [001] This application concerns the Utility Model Patent “CONSTRUCTIVE ARRANGEMENT IN CUTTING AND COLLECTION PLATFORM COUPLED TO THE FORAGE HARVEST”, particularly for improvement carried out in equipment designed for cutting and collecting forage plants such as grass, father-in-law, oats and others. The model consists of a cutting and collecting platform that can be attached to a forage harvester, in order to cut, collect the material to be launched in any area, standing out for presenting, in relation to the state of the art, a series of extraordinary advantages, which result in functional, constructive, operational improvements, in addition to others to be better understood throughout this specification, particularly by eliminating the need for a reel to launch the cut material, and creating, in this type of equipment , an unprecedented transmission system.

STATE OF THE TECHNIQUE [002] Patent application Pl 0203771-8, from the same depositor, is known from the state of the art, which consists of a cutting and collecting platform, coupled to a forage harvester.

[003] That is, the depositor cites as an advantage the fact that the cutting and collecting platform can be coupled or decoupled, allowing the forage harvester to be used for other forage plants such as corn and sugar cane, just uncouple the platform, without the need to purchase another machine, which makes the equipment multipurpose.

[004] In the aforementioned state of the art equipment, a cutting platform composed of elements that rotate in high rotation was highlighted, so that, due to this high rotation, the cut material does not even fall to the ground, in order to provide a uniform cut in the clumps of forage plants, with positive results in terms of regrowth and soil reduction.

[005] On said platform of the previous patent application, a second element called a tipping roller was provided, in the form of a rectangular prism with claws

2/5 trapezoidal edges, with the cut material being routed integrally to the helical roller, from where it went to the ensilage.

FROM THE PRESENT UTILITY MODEL [006] The new cutting and gathering platform, object of this utility model patent, can, like the previous one, be coupled or uncoupled to a harvester, however, either to operate with forage plants such as grass , sorghum, oats and others, or release the forage harvester for use in other crops.

[007] However, aiming at the performance of the equipment, the inventor implements important improvements in the cutting and collecting platform, which is presented here in versions for three or five cutting and launching discs, which are triggered from a set of sprockets that receive the transmission from the PTO of the agricultural implement. The cutting and launching discs have a combination of synchronism and direction of rotation, in addition to being designed conically, which creates better space for the entry and cutting of products, where the so-called launchers that take the cut and collected products and the they launch with great speed into the equipment, aided by deflectors, in order to be passed on to the unit that bites the product, where the process is finished being the material laced to the outside of the equipment.

[008] In this model, as a result of this new constructivity, both the tipping roller and the helical roller are eliminated, due to the operational and rotational interaction between the cutting and launching discs, this elimination was achieved.

[009] With the new transmission technique adopted in this new cutting and retracting platform, it becomes possible to guarantee the efficiency of the equipment's operating system with a minimum of losses, even in severe operating conditions, in addition to maintaining the equipment's side free, which avoids folding the product to be worked.

[010] With the new transmission technique adopted in this new cutting and retracting platform, it becomes possible to guarantee the equipment's operation with a minimum of losses, even in severe operating conditions, in addition to keeping the equipment side free, which prevents folding of the product to be worked.

3/5 [011] Additionally, the elimination of components such as tipping roller and helical roller, high cost components, makes the equipment less expensive, more accessible to farmers, with less maintenance and highly reliable.

[012] Thus, the present equipment, in addition to the mentioned advantages, has in relation to the state of the technique indicated, less number of moving parts, therefore less subject to breakage and maintenance. Also with regard to the equipment, the manufacturing process of the equipment is significantly optimized on the assembly line.

4/5 and collection that can be used in conjunction with a forage harvester, particularly for cutting, collecting forage material such as grass, sorghum, oats and others.

[015] Figure 1 shows the cutting and collecting platform (P) coupled to the forage harvester (F), showing the coupling means (1), as well as the chassis (2) of the set supporting the forage harvester. itself (E) where the product previously cut and collected is chopped to be thrown out of the equipment. This figure also shows the coupling points (3) to the tractor or similar, as well as the coupling (4) to the power take-off.

[016] The forage harvester (E) has conventional characteristics, being equipped with a high discharge nozzle (5) and a unit (6) to chop the material.

[017] Still in the aforementioned figure 1, there is shown the cutting and collecting platform (P) coupled to the forage harvester (E), being that, on the axis (7) coming from the coupling to the power take-off (4), there is a reducer (8) supporting the chassis (2), from where another transmission shaft (9) is projected, providing a predetermined rotation in RPM, and this transmission mechanism is coupled to the mechanism (10) provided in the cutting platform and (P), which can be viewed in isolation in figure 2.

[018] The transmission mechanism (10) of the pick-up cutting platform (P) is such that it activates a turning element (11) whose axis (12) is, with the cut and pick-up platform (P) coupled to the harvesting harvester. forage (E), positioned on the part of said platform (P), from where projected towards the previous part of it, a means of transmission (13) as a belt or similar, which extends to an anterior reduction box (14) , which is connected, by an axis (16), to a substantially L-shaped lower guide (15) where a series of contiguous sprockets (17) of the same module are positioned, with the sprockets (17A) having their axes coupled to the axes of the cutting and launching discs (19), which can be in number of three or five, in the versions shown here, but they can still be in greater number, these cog wheels (17A) designed so that the discs of contiguous cut and throw (19) rotate in opposite directions, causing the previously cut material to be launched with great speed into the equipment.

5/5 [019] The cutting and throwing discs (19) are seated on the guide (15), so that they have a predetermined inclination and a truncated configuration aiming to produce perfect against the products and generate the necessary space for it to be launched for inside the equipment, reaching the unit (6) where it is chopped.

[020] As shown in figure 2, the cutting and launching discs (19) have a cutting device (20) below and, above, the tapered disc itself, in which the so-called launchers (21) are arranged in the form fins positioned on circular flaps (22).

[021] It is important to emphasize that the present model, in addition to the advantages already mentioned, has as an important characteristic the release of the side of the equipment, leaving it free and, thus, preventing the product from bending; also, it has a lower number of moving parts, resulting in less maintenance at break rates. With these characteristics, the equipment manufacturing process is also optimized.

[022] The entire set described above is housed inside a fairing (23) that internally provides deflectors (24) that direct the cut material to the ideal point at the entrance of the cutting and launching platform, so that it is launched with the proper speed for the unit (6). In the front part of the fairing (23) there are guides (25) of material entrance in the cutting and launching platform (P), which act both in the lateral direction and in the height.

[023] Figure 9 shows an optional schematic construction of the cutting and launching platform (P) with five cutting and launching discs (19), so that two inlet lines (26) of material between spinning discs in reverse are established , however, maintaining the entire construction in terms of driving and transmitting movements.

[024] The cutting and launching platform (P) can be released, or decoupled from the forage harvester (E), allowing the latter to be used in other types of crops.
