Description

Scope of Application of the Utility Model [0001] This utility model refers, in general, to a new constructive arrangement applied to the slats of the elevator assembly of a harvesting machine, particularly those intended for harvesting tall and stemmed plants, such as sugarcane and sweet sorghum. More specifically, this new constructive arrangement was designed and developed to significantly simplify production lines and, mainly, the maintenance process of these slats and the elevator assembly of harvesting machines. Fundamentals of the Utility Model [0002] In the state of the art, there are numerous models of agricultural equipment and machinery developed to increase productivity in the harvesting of various types of plant crops, for example, grain harvesters, forage harvesters, and also harvesting machines for so-called tall and stem-bearing plants, such as sugarcane and sweet sorghum. [0003] The machines designed for harvesting these tall, stem-bearing plants are designed and developed to facilitate the harvesting of this specific type of crop, because their intrinsic characteristics require specific conditions for their proper processing, from cutting to transfer to transshipment vehicles and/or trailers. [0004] In this context, it is known that these harvesting machines for tall and stem-bearing plants comprise a chassis that supports a series of conveyor and chopper rollers responsible for conveying and chopping the cane into billets, which are transferred to the transshipment vehicles and/or trailers via an elevator assembly. [0005] This elevator assembly consists of a housing structure, usually metallic, made up of a plurality of individual parts and pieces which, when combined, support various components, such as the mechanisms responsible for moving the slats, which guide and drag the billets and harvested material to be dumped into the transfer vehicles and/or trailers that move parallel to the harvesting machine when in operation, in order to, by directing the upper outlet end of the elevator assembly towards the transfer vehicle and/or trailer, promote the transfer of the harvested material. [0006] However, despite being functional, it was observed that the construction method of these elevator assemblies and, more particularly, the construction of the slats, according to the practices known in the state of the art, could be improved and enhanced, considering some factors related to the production line, assembly, but mainly for the maintenance of these assemblies. [0007] More specifically, as can be seen, the cleats known in the state of the art are normally made up of a set of welded parts, forming a single inseparable unit, that is, the side supports used for fixing to the chain are welded to the ends of a plate responsible for dragging the harvested material towards the distal portion of the elevator assembly. Therefore, if any part of the cleat is damaged, it will necessarily be necessary to replace the entire cleat, since the parts are not separable, that is, if the material drag plate is damaged, the operator will need to replace the entire cleat, regardless of whether the side supports are in perfect condition. As a result, this type of construction ends up affecting the maintenance costs of harvesting machines. [0008] As experts in the field should note, this type of inconvenience can substantially impact the logistics and maintenance costs of harvesting machines, since the slats are components that are frequently subjected to stress and sudden impacts, considering that the harvested material is literally dumped onto the elevator assembly and, consequently, onto the slats, creating a high risk of breakage and damage to the slats. For this reason, considering that the maintenance of these parts involves the complete replacement of the slat, there is a considerable cost that farmers and producers need to provision for, which ultimately affects the productivity and profitability of the harvests. [0009] Furthermore, it is worth mentioning that, due to the production of these state-of-the-art slats involving a welding process, with the use of equipment and operators trained to perform the task properly and safely, there is a relatively high cost for a part that needs to be replaced fairly frequently and, therefore, another inconvenience that ultimately directly affects the manufacturing and maintenance costs of harvesting machines and, indirectly, the profitability of the harvests. [0010] Thus, it is observed that state-of-the-art machines, especially those intended for harvesting sugarcane and sorghum, reveal some drawbacks and limitations that can directly affect the production, assembly, and maintenance of the machines, and more particularly with regard to the complexity of the production and maintenance of the elevator assembly slats. Therefore, it becomes desirable to obtain slats with more versatile constructions in order to eliminate or minimize the drawbacks of the state of the art,
