Description

TECHNICAL FIELD [001] This utility model patent application belongs to the agro-industrial segment, more specifically applied in the agricultural industry to improve the quality of grains before processing, notably improving the fastening hangers used in the sieve boxes of pre-cleaning and cleaning machines. With a simple and robust construction, these hangers optimize maintenance time and reduce production downtime due to unexpected machine failures. Furthermore, they increase the component's lifespan, significantly improving manufacturing efficiency. The design consists of a set of plates fixed to the chassis and boxes, allowing them to swing through the eccentric rotation of the shaft. HISTORY OF THE TECHNIQUE [002] As agriculture modernized, especially from the 19th century onwards with the Industrial Revolution, there was a growing demand for high-quality grains in large quantities. Impurities in the grains could cause problems in subsequent processes, such as milling and storage, and reduce the quality of the final product. [003] With the advancement of technology, machines emerged capable of performing tasks that were previously done manually. The introduction of steam engines and, later, internal combustion engines, allowed the development of more complex and efficient agricultural equipment. The first versions of pre-cleaning machines used sieves and fans driven by mechanical force. [004] During the 20th century, agriculture became increasingly industrialized. This included the mechanization of various stages of the agricultural production process, from planting to harvesting and post-harvesting. Pre-cleaning machines became essential to ensure that harvested grains were processed efficiently and with high quality. [005] Over time, these machines have undergone several innovations and improvements. Technologies such as density separation, the use of optical sensors, and automated control have been incorporated, making pre-cleaning machines more precise and efficient. [006] Globalization and the increased global demand for food have further driven the need for high-quality grains. Pre-cleaning machines have become a vital component of the global production chain, ensuring that exported grains meet international quality standards. State of the Art Analysis [007] Research conducted in specialized databases revealed documents related to pre-cleaning and cleaning machines, such as document number BR 102018010796-8, which deals with a "PRE-CLEANING MACHINE WITH A SCRAPING SYSTEM FOR CLEANING SIEVES TO PREVENT RESIDUES FROM OBSTRUCTING THE SIEVE CAVITIES, OBTAINING BETTER RESULTS AND PERFORMANCE IN GRAIN CLEANING". This pre-cleaning machine is used in the grain cleaning process, where grains enter with a large quantity of impurities. These impurities remain trapped in the sieves, and with the new rotary vane system (Figure 5), whose main characteristic is the cleaning of the sieve cavities (Figure 4), leaving them clean until the next cycle, there is a continuous reduction in labor, as it will not be necessary to manually clean the machine. an improvement in performance during the grain cleaning process. [008] Document No. BR 102014009702-3, which deals with an “IMPURITY SEPARATION MACHINE FOR ANALYSIS AND PRE-CLEANING AND/OR CLEANING OF GRAINS AND/OR SEEDS, ON A LABORATORY SCALE”, the present invention consists of air and flat sieve equipment, made of wood and/or metal, which allows the removal of impurities larger, smaller and much lighter than grains and/or seeds, through a set of flat sieves, with a tilt control device according to the product being used and the type of impurities to be removed, in addition to air flow control and regulation in the fan. It presents results comparable to those of commercially available machines. It operates on a small scale, from 4 to 80 Kg.h-1 of samples. [009] Document No. PI 0605574-5, which deals with a “PRE-CLEANING MACHINE WITH SWEEPING AND GRAIN RECOVERY SYSTEM FOR GRAINS PRECIPITATED ON THE GROUND AFTER HARVESTING PROCEDURE”, represented by an inventive solution in a pre-cleaning machine (A) composed of a pair of wheels (A2), with a hitch (A3) for connection to a traction vehicle, having a motor (A4) to which a compaction system (1) and a grain sweeping and recovery system (B) are connected, where once put into operation it guarantees excellent performance in recovering grains (B) that precipitate onto the ground during the harvesting procedure, being especially useful when used in coffee plantations where harvesting is carried out by means of specialized mechanical harvesters for this purpose, minimizing losses for the farmer due to grain loss and thus guaranteeing the maximization of the value of a grain harvest. [010] However, the equipment mentioned above, despite fulfilling its function, has limitations in its construction. In addition, the pre-cleaning and cleaning machines currently in use utilize metal plates, commonly called rails, as suspensions for f
