Description

"ARRANGEMENT APPLIED TO SUGAR MECHANICAL HARVEST"

It addresses the present Utility Model Patent application of an unpublished "ARRANGEMENT APPLIED TO SUGAR MECHANICAL HARVEST"; especially of equipment for harvesting whole sugarcane in a fully mechanized manner to be coupled to the third point of the tractor, the highlight of which is to convey, by conveyor belt, the entire cane which is deposited on a solidarity tipped trailer, also having a herbicide spraying system adjoining the track, as well as another system of application of inputs located in the bordering region of the tractor hydraulic, thus enabling the mechanized harvesting of the whole cane.

Sugarcane cultivation tends to become fully mechanized, eliminating the use of labor in crops and other archaic procedures, such as manual pre-burn burning, which causes great environmental damage.

Large and cost-prohibitive equipment is currently known to small and medium-sized farmers, capable of performing various operations to fulfill the inherent harvesting stages, already established in the field, but in a mechanized manner. , smaller harvests are anticipated in some patent documents, such as PI 9204564-2 "Improvements in Sugarcane Harvester", through which extraordinary operational resources are obtained at both as well as preparation and quality of the harvested and cut product, still incurring a significantly higher productivity compared to the current state of the art, taking the harvester indicated for sugar and alcohol plants, composed of a chassis supported by tires, whose axles are provided adjustable eccentric mechanisms according to the desired fixed height in relation to the ground; 1 of the equipment are the parallel toothed rollers, situated between the side plates that guide the entrance of the cane, said rollers supported in corresponding chassis, so that the collected cane is subjected to a first cut in the knives, thereafter to the horizontal knobs, They then move to the rotor where, after being cut into tails, they are centrifuged and thrown out and, with the aid of fans, reach the main chute until dispensed by the diffuser, while a second diffuser acts, just below that, producing air. necessary for the leaves and other residues to fall, by gravity, to be separated, and the bollards are collected in the transport vehicle which moves parallel to the machine, while the leaves and others are thrown away from the same vehicle ".

The equipment anticipated above works by means of a tractor element being coupled to the third point of it, forming a compact solution for harvesting the sugarcane captured by front rollers to the interior of the machine where it is cut for subsequent mincing performed in the cutting rotor where suffers forced ventilation for cleaning purposes.

M U - 8600385-2 "Constructive Forage Harvester Arrangement" for uninterrupted harvesting of cane and other products that are cut or minced by equipment and spouted into an transhipment vehicle. The mesh harvester, which can be coupled to the tractor, has a substantially "V" inlet which, with the aid of an upper bulkhead, directs the product to be cut and minced to drag rollers and thence to the helical knives on both sides of the rotor. The main highlight of this equipment is that it directs the shredded material to the outlet spout without contact with rigid parts, thanks to the rotary movement of the rotor and knives.

As can be seen the models of early compact harvester, regardless of their improvements, produce chopped sugarcane which presents a number of drawbacks in the operational part of the sugar-alcohol process, such as the fact that it needs to be processed quickly to avoid pericibility due to more fermentation. accelerated. On the other hand, chopped sugarcane carries a large amount of soil and other solid waste, making it difficult to produce sugar and alcohol, as it cannot be washed, which would lead to the loss of sucrose. Finally, such equipment requires a transhipment vehicle in parallel with the discharge spout outlet.

The aim of the present invention is to enable a whole cane harvester captured at the front of the machine by means of collecting rollers that direct the cane to the cutting knives and in the upper front portion, the claimed equipment has a cutting device. leaves able to vent the passage through the collecting rollers and then the entire cane follows by conveyor belt to the rear reservoir with hydraulic cylinder that makes it tilting. In addition, the innovative harvester features a herbicide spraying system located under the lower mat, as well as an input application system thrown in the region adjacent to the header.

In addition, the cutting of the whole sugarcane does not harm the buds, allowing the destination also as plant sugarcane or a period of stay in the field before grinding, without risk of danger, of at least 72 hours and, depending on temperature, even longer. It should also be noted that a single tractor holds the equipment and the tipping trailer type trailer.

In short it can be highlighted as main advantages of the innovative equipment:

• Harvesting the entire cane;

• No aggression to sugarcane bud;

• Easy operation on any type of terrain;

• Low cost of acquisition and maintenance;

• Exemption from the use of transhipment;

• Remaining of cut cane in the field for a minimum of 72 hours (3 days);

• Use of a single tractor for the cutting process and the tilting reservoir (trailer);

• Possibility of spraying pesticides and application of inputs simultaneously to sugarcane cutting;

• The whole cut cane does not cause damage to the bud, which allows its destination for planting.

Innovation can best be understood from the accompanying drawings in which they are illustrated by way of illustration and not limitation:

The "MECHANICAL SUGAR CANE APPLIED ARRANGEMENT" object of this Utility Model Patent Application consists of a harvester (1) provided with a head (2) for coupling to the third point of a tractor element (T) in that the cane is directed by helical lifter (3) to the front rotor (4) with lower knives (5) acting in conjunction with the plant pointer cutter (6), and hence the entire cane follows at the intersection of a pair (7) to a conduit (8) which discharges the cane into a swiveling rear reservoir (9), furthermore, the harvester (1) has a herbicide spraying system (10) and other input application system (11). ) that run in parallel with sugarcane cutting.

More particularly, the harvester (1) has a head (2) to be coupled to the third tractor point (T), consisting of a chassis (11F and 11L) supported by tires (12). The front frame (11F) comprises a pair of helical lifters (3) which run in parallel with the canopy cutter (6) which is directed to the front rotor (4) with lower knives (5) which cut the cane directing it all the way to the treadmill (7). The rotary pointer cutter (6), equipped with rotary knives and knobs, is vertically movable since it is supported by a compatible structure (E) and connected to a driving piston (13). On the other hand, the parallel tracks (7) also feature the adjustable interleaving (V) with damping mechanism that is adjusted according to volume and optimizes the cane routing. Thus, the entire cane is poured into the discharge duct (14) where a pair of steering rollers (15 I and 15S) are evident where the lower roll (151) has a leak (16) for solid waste output accompanying the harvested material, the rotation and torque of the rollers (151 and 15S) being sufficient to throw the cane into the rear reservoir (9) supported on the side frame (11L), pivotable by means of piston (17). Finally, the harvester (1) has a herbicide spraying system (10) just below the lower mat (7), as well as an input application system (11) located on the head (C) of the equipment.
