Description

1 / 16 “ARRANGEMENT INTRODUCED IN AN AGRICULTURAL IMPLEMENT FOR THE DISTRIBUTION OF A PRODUCT OF VARIABLE GRANULOMETRY, SUCH AS MEAL, AGGLUTINATED OR POWDERED PRODUCTS” FIELD OF INVENTION

[001] The present invention belongs to the field of agricultural implements, more specifically to devices for the distribution of products of variable particle size, such as bran, agglomerates or powders. This invention's main difference from prior art solutions is the use of a demountable, weld-free metal conveyor belt. This feature allows the use of different materials in manufacturing and facilitates maintenance. In addition, the implement incorporates a hydraulic drive system with a suspended pump that eliminates the cardan shaft, distributor discs with tilt adjustments that optimize material distribution, and wheel track adjustment that retracts the structure's beams, reducing the implement's maximum width for transport. SUMMARY OF THE INVENTION

[002] Agricultural implements for the distribution of products of variable particle size, such as bran, agglomerates or powders, are known technologies in the state of the art. Comprising a chassis to be hitched to three-point hitch systems or simply towed by a tractor unit, usually a wheeled tractor.

[003] The basic structure of the implement consists of a cargo box or reservoir, which stores the material to be distributed. This reservoir is manufactured from resistant metal sheets, often treated with anti-corrosion coatings to ensure durability and Petition 870250066184, dated 07 / 30 / 2025, page 6 / 23 2 / 16 resistance to adverse conditions in the agricultural environment. Internally, the box walls are inclined to facilitate the flow of material towards the transport system, preventing product accumulation in specific points and ensuring continuous and uniform feeding to the conveyor belts.

[004] The tractor hitch system, as already described, whether by means of a three-point hitch or by trailing hitch, is designed to support the weight of the loaded implement and offer stability during operation. In the case of the three-point hitch, the attachment uses adjustable metal rods that connect the implement to the hydraulic arms of the tractor unit, allowing for precise lifting and control of the implement's height relative to the ground. In the trailing hitch system, a fixed hitch is used, connecting the implement to a support on the tractor and ensuring that it follows the vehicle's movements during operation.

[005] The implement has a conveyor belt system that transports the material from the reservoir to the distribution discs. These belts are manufactured with high-strength materials, such as fabric-reinforced rubber or polyurethane, or spaced metal cleats joined by chains. The design of the rubber belts may include textured elements, such as grooves or fins, to increase material grip and ensure its uniform movement, even under adverse operating conditions, and the cleat belts may have specific shapes that prevent intermittent material spillage onto the discs.

[006] The conveyor belts are driven by a transmission system that uses the power take-off (PTO) of the Petition 870250066184, dated 07 / 30 / 2025, page 7 / 23 3 / 16 tractor. A driveshaft connects the PTO to a set of gears or pulleys located on the implement, transmitting rotation to the track axles. In more advanced models, the drive can be hydraulic, with motors controlled by adjustable valves that allow the operator to regulate the track speed directly from the tractor cab. This control offers great flexibility to adapt the distribution rate to the specific needs of the field and the type of input used.

[007] The distributor discs, located at the rear of the implement, receive the material transported by the conveyor belts and are responsible for its uniform application to the ground. These discs are made of wear-resistant metallic materials and feature radial fins that ensure controlled dispersion of the product over a predetermined area. The rotation of the discs is generated by the same transmission system that drives the conveyor belts, using belts, pulleys, or hydraulic motors. The rotation speed of the discs can be adjusted to alter the distribution range, ensuring greater precision in different types of application.

[008] Another relevant technical aspect of this implement is the track width adjustment system, which allows the overall width of the implement to be changed to meet different transport and field operation conditions. The adjustment system consists of telescopic or sliding mechanisms coupled to the implement's wheel axles. In some models, the adjustment can be made manually, using fixing screws that allow the position of the side wheels to be changed. In more modern models, the system is hydraulic. Petition 870250066184, dated 07 / 30 / 2025, page 8 / 23 4 / 16 allowing the operator to adjust the track width quickly and precisely without leaving the tractor cab.

[009] The integrated operation of all implement systems ensures high efficiency and versatility. The operational process begins with coupling the implement to a tractor unit such as a wheeled tractor and filling the reservoir with the material to be distributed. The operator adjusts the implement height, in the case of a three-point hitch, and configures the track and disc systems to operate at the speed appropriate to the field conditions. During operation, the material is transported by the tracks to the distribution discs, which disperse it uniformly on the ground. The application rate is kept constant by synchronizing the track speeds and the implement's movement, allowing the operator to achieve the desired levels of uniformity and efficiency.

[0010] When fieldwork is completed, adjusting the track width allows the implement to be prepared for road transport. Although side wheels are retracted or adjusted to reduce the overall width of the implement, facilitating movement between different areas, there is still part of the structure that extends beyond the desired perimeter.

[0011] Although this type of implement functions relatively satisfactorily, there are a number of disadvantages, including the materials and processes used in the construction of the track, which present a number of operational and construction problems that negatively impact its efficiency, functionality, and cost. The use of such materials and processes can result in a track with deficiencies in Petition 870250066184, dated 07 / 30 / 2025, page 9 / 23 5 / 16 material flow, especially in the case of products with variable particle size, compromising the uniformity of distribution.

[0012] Track gauge adjustment that keeps part of the implement structure outside the nominal usable width permitted by law also presents significant challenges. During road transport, these implements may exceed established width limits, which implies potential legal penalties and movement restrictions. This configuration forces the operator to perform partial disassemblies or use specialized transport, increasing costs and reducing practicality. In the field, an improperly adjusted track gauge can result in poor weight distribution and implement instability, compromising the accuracy of material application and increasing the risk of structural damage to the equipment.

[0013] The implement has a complex transmission system for rotating the discs; the disadvantages of this power transmission system using multiplier or reduction gearboxes are well-known, both in terms of operation and maintenance. These gearboxes are designed to adjust the tractor's power take-off rotation ratio and synchronize the position of the launching blades, preventing collisions between them.

[0014] Transmission systems with multiple moving components are more likely to experience mechanical failures due to wear, especially in agricultural environments where exposure to dust, moisture, and impacts is constant. Maintaining such systems requires specialized labor and is costly, with periods of downtime. Petition 870250066184, dated 07 / 30 / 2025, page 10 / 23 6 / 16 extended in case of repairs. The complexity of the configuration also makes the system less adaptable to different working conditions, hindering quick operational adjustments in the field.

[0015] Thus, the objective of the present invention is to provide an arrangement introduced into an agricultural implement for distributing a product of variable particle size, such as bran, agglomerates or powder, which has a detachable and weld-free metal conveyor belt with overlapping cleats, so that there is no spacing for the product to fall between the cleats, thus eliminating the lower barrier that runs along the perimeter of the conveyor belt. The overlapping of the cleats also forms steps with specific geometries such as rectangular, semi-rectangular or other known and suitable geometries that provide increased adhesion of the material to ensure its uniform movement.

[0016] It is also an objective of the present invention to provide an arrangement introduced into an agricultural implement for distributing a product of variable particle size, such as bran, agglomerates or powder, equipped with a hydraulic drive system with a suspended pump that eliminates the cardan shaft.

[0017] Additionally, the present invention aims to provide an arrangement introduced into an agricultural implement for distributing a product of variable particle size, such as bran, agglomerates or powder, equipped with a means of direct hydraulic actuation of the distribution discs, thereby eliminating the use of systems with synchronized transmission boxes. Petition 870250066184, dated 07 / 30 / 2025, page 11 / 23 7 / 16 rotation.

[0018] Additionally, the present invention aims to provide an arrangement introduced into an agricultural implement for distributing a product of variable particle size, such as bran, agglomerates or powder, which has a gauge adjustment system by parallel bars, which retracts the beams of the structure reducing the maximum width of the implement for transport.

[0019] Finally, the objective of the present invention is to provide an arrangement introduced into an agricultural implement for distributing a product of variable particle size, such as bran, agglomerates or powder, that is easy to construct, maintain and cost-competitive.

[0020] These and other advantages and benefits are achieved by providing a device introduced into an agricultural implement for distributing a product of variable particle size, such as bran, agglomerates or powder,

[0021] The first objective of the invention is achieved by introducing a conveyor belt equipped with overlapping cleats. This design completely eliminates the spacing between the cleats, preventing the product from leaking or falling between the conveyor belt elements. This eliminates the need for a lower barrier that runs along the perimeter of the conveyor belt, reducing structural complexity and maintenance requirements. This approach not only improves the efficient transport of materials with varying particle sizes, but also ensures greater reliability over time, preventing the accumulation of residue and premature wear in critical areas. Petition 870250066184, dated 07 / 30 / 2025, page 12 / 23 8 / 16

[0022] Furthermore, the invention incorporates a direct hydraulic drive system for the distributor discs, eliminating the need for traditional systems based on multiplier or reduction gearboxes. This solution significantly reduces the implement's complexity by eliminating heavy and failure-prone components such as additional gears and pulleys. The direct drive is designed to operate more efficiently, minimizing mechanical losses and ensuring precise and reliable power transfer from the tractor's power take-off to the discs. This simplified system reduces maintenance costs, increases durability, and improves consistency in input application, even under intensive working conditions.

[0023] Finally, the invention fulfills the objective of ensuring a functional and efficient gauge adjustment by means of movable side bars. This system maintains the maximum usable width of the implement within the limits permitted by law, regardless of the gauge configuration. The side bars provide a robust and adjustable mechanism that allows for practical and quick adjustment of the implement's width, without compromising its stability or efficiency during fieldwork. In addition to optimizing operation in different growing conditions, this functionality ensures that the implement is always suitable for road transport, eliminating the need for disassembly or complex adjustments.

[0042] The present invention comprises an arrangement introduced in an agricultural implement for distributing a product of variable granulometry, such as bran, agglomerates or powder, equipped with a chassis (01), constructed of steel beams or tubes, supported by ground wheels (02) and preceded by means of hitch on a tractor unit, carrying at the top a reservoir or cargo box (03), which forms an enclosure provided with transverse and longitudinal walls having an upper opening for loading and another lower one for unloading from the conveyor system (04) this conveyor system is constituted by a modular structure designed for the transport of materials in agricultural implements.The conveyor belts are composed of interconnected segments, which have integrated cleats (05) with a shape that maximizes the drag of the transported material, ensuring continuous and uniform movement, even with products of variable particle size, such as bran, agglomerates or powder.

[0043] Each track module is articulated, facilitating its movement along axles or pulleys, according to the implement's drive system. The cleats have a design that partially overlaps, eliminating any Petition 870250066184, dated 07 / 30 / 2025, page 17 / 23 13 / 16 significant spacing between segments. This configuration prevents material from seeping in or escaping through the gaps in the conveyor belt, eliminating the need for lower barriers. This feature reduces maintenance requirements and optimizes transport efficiency.

[0044] In addition, the conveyor drive system is driven by a set of (06) split gears to facilitate coupling and maintenance. These gears are divided into two parts, which are joined by means of screws or other non-permanent joining means, arranged at points along their circumference. The split construction allows for assembly, disassembly and replacement, offering great practicality in maintenance and replacement operations.

[0045] The gear design is comprised of internal and external teeth, which enhances its functionality in the track transmission system. The internal and external teeth are designed to fit into track fasteners or guides, ensuring precise alignment and efficient torque transmission via the drive shaft (07). This shaft is connected to the implement's hydraulic transmission, ensuring consistent force application for track movement. The modular and articulated system facilitates maintenance and adjustment, while integration with the drive components ensures that the tracks operate synchronously with other elements of the agricultural implement, such as the distributor discs. The robust and functional design is ideal for operating in demanding environments and resisting the abrasiveness of the transported materials, ensuring durability and Petition 870250066184, dated 07 / 30 / 2025, page 18 / 23 14 / 16 reliability in use.

[0046] The implement also features a disc system (08), comprising a partitioned configuration that shares the same hypothetical center of the drive shaft and has a semicircular geometry in its central region, designed to perform the uniform distribution of materials of varying granulometry in agricultural implements. This disc has a circular central core with perforations that facilitate its coupling to a drive shaft by means of screws, ensuring a firm and stable fixation. The semicircular geometry distributes the material along its outer perimeter, optimizing the flow and providing uniform coverage on the ground.

[0047] The discs have integrated radial vanes to propel the material across the distribution swath, utilizing the centrifugal force generated by the disc's rotation. These vanes have a specific position that directs the material across the entire area, generating reach and uniformity of application. The vane design is robust and engineered to withstand wear caused by abrasive materials such as fertilizers or soil amendments.

[0048] The semicircular central perimeter acts as the disc itself and serves to balance the weight distribution and reduce vibrations during operation. This mechanical balance increases the precision of the application, while extending the system's lifespan by minimizing wear at specific points. This disc system is particularly efficient for agricultural work requiring wide and uniform coverage, offering versatility and reliability in different conditions. Petition 870250066184, dated 07 / 30 / 2025, page 19 / 23 15 / 16 field.

[0049] The disc in question is driven by a hydraulic motor (09), which is operatively associated with a support (10), this support is constructed of metallic material, such as steel or other resistant alloy, the base of the support is equipped with a fastening system to the chassis of the agricultural implement, providing a firm and stable mounting. This base contains oblong holes for screws, allowing fine adjustment of the position of the assembly.

[0050] This fine adjustment is achieved by selectively adjusting the respective assembly in the Cartesian planes yez, represented by the dimensions (A) and (B) in figures 07, 08 and 09.

[0051] The hydraulic motor (09) is mounted in an elevated position relative to the disc. The connection between the hydraulic motor (09) and the distributor disc (08) is made through a transmission shaft coupled to the motor output, eliminating the need for intermediate components such as gears or belts.

[0052] The implement also features a track width adjustment system, which allows lateral displacement of the wheels to change the width of the agricultural implement in a practical and efficient way. The mechanism consists of a central structure (11) fixed to the main chassis of the implement, which houses the wheel support bars. These bars are designed to move parallel to the central structure, allowing adjustment of the wheel position without compromising the stability of the assembly.

[0053] The parallel bars (12a-12b) are fixed to the wheel axle via joints that ensure correct alignment during adjustment and operation. The movement of the bars Petition 870250066184, dated 07 / 30 / 2025, page 20 / 23 The 16 / 16 system is enabled by a drive system, which can be manual or hydraulic. In a manual configuration, adjustable screws or locking pins are used to fix the bars in the desired position, while in a hydraulic configuration, hydraulic cylinders control the lateral displacement, providing greater practicality and speed in adjustment.

[0054] This system allows the overall width of the implement to be altered to suit different transport and field operation conditions. During road transport, the bars can be retracted to reduce the width, ensuring compliance with traffic regulations. In field operation, the bars can be adjusted to align the wheels with the tractor tracks, minimizing soil compaction and optimizing implement stability.

[0055] Although only one constructive form has been described for the arrangement introduced in an agricultural implement for distributing a product of variable particle size, such as bran, agglomerates or powder, it is obvious that eventual changes in forms or arrangements may occur, without departing from the scope of one or more claims accompanying this descriptive report.
