The system significantly improves silage preservation, reducing nutritional losses and optimizing storage and transport. STATE OF THE ART

[002] A silage baler and wrapper is a piece of agricultural equipment that forms compact bales of chopped forage and wraps them in plastic film to create anaerobic conditions that preserve the silage.

[003] An example of a bagging and compacting machine for silage and / or storage of other particulate materials in general is disclosed in BR102013026252, which comprises a structure composed of a material inlet nozzle, inside which are positioned screw shafts driven by the motor, the screw shafts conveying the material through the bagging and compaction nozzle, where a table is positioned, which is sliding on rails and equipped with a stop with a brake device operated by a lever and equipped with a sensor.

[004] A bagging and compaction apparatus for particulate materials is described in BR202019023497, where the apparatus comprises a tall and wide structure for storing the material, an internal funnel for adding material, two Petition 870250104250, dated 11 / 14 / 2025, page 5 / 21 / 8 augers, coupled to the motor, protected by the housing. The two augers that convey the material to the table that slides on the rails, equipped with a stop, with brake devices and a sensor.

[005] Document CN218537366 discloses a fully automatic silage baling and wrapping machine. The equipment includes a frame, a baling device, a film baling device, a primary loading silo, and a secondary loading silo. The baling device is provided with a net device, and the frame is also provided with a material recovery device and a power control device. The material recovery device is located below the baling device and the film wrapping device. The rear end of the secondary loading silo is coupled to the front end of the primary loading silo to facilitate material transport. The secondary loading silo includes a storage conveyor, an arc-shaped enveloping material locking cover, a silo base, a secondary support, and a material diversion device.The material diversion device is located at the rear end of the secondary loading silo. The utility model performs the action of diverting material in the secondary loading silo, providing the material diversion device, continuously and uniformly transferring material from the secondary loading silo to the primary loading silo, effectively improving the uniformity and stability of forage feeding. PROBLEMS WITH THE TECHNIQUE

[006] Although similar equipment exists, with us Petition 870250104250, dated 11 / 14 / 2025, p. 6 / 21 / 8 cases revealed, these devices do not perform the compaction and baling operations on the plastic film automatically. The equipment that does perform this, for example, CN218537366, is a device that includes a frame, a baling device, a film wrapping device, a primary loading box and a secondary loading box. The baling device is equipped with a net device, the frame is also equipped with a material recovery device and a power control device, the material recovery device is located below the baling device and the film wrapping device, the rear end of the secondary bucket is coupled to the front end of the primary bucket to cooperate with the transport of the material, and the secondary bucket includes a storage conveyor.The secondary cargo box includes a storage conveyor, an arc-shaped locking material cover, a box base, a secondary support, and a switching device, with the switching device located at the rear end of the secondary cargo box. PROPOSED SOLUTION

[007] Although other baling and packaging machines exist, these machines are larger or consist of two separate units. The proposed machine is a monobloc, where all the equipment necessary for its operation is mounted on the same chassis.

[008] Another distinguishing feature of the machine is its capacity Petition 870250104250, dated 11 / 14 / 2025, page 7 / 21 / 8, to process multiple types of forage, such as corn, grass, straw, agricultural residues and other materials, providing a sustainable and economical storage and transportation system.

[009] The machine is composed of multiple integrated systems that guarantee its efficient and automated operation. It includes a reinforced chassis, manufactured with high-strength steel, ensuring durability and stability. The anti-corrosion paint provides protection against moisture and wear. The electronic control panel has a user-friendly interface for simplified operation and real-time monitoring.

[010] The feeding and baling system contains an automatic feeding conveyor that directs the forage to the compression chamber. The high-density compression chamber compacts the forage uniformly to optimize bale formation. Pressure and weight sensors monitor the compaction level, ensuring uniform bales between 100 kg and 200 kg. The electro-electronic pressing system offers efficient compaction with automatic pressure adjustment. The packaging system features controlled rotation, which keeps the bales stable during the wrapping process. Mechanical arms with tension sensors maintain uniform application of the plastic film. Automatic film cutting prevents waste and reduces cycle time. The film layer configuration is customizable from 2 to 6 layers, according to the sealing needs.

[011] The electronic control system comprises the intelligent digital panel, with control of speed, compression and number of film layers. Safety sensors detect faults and Petition 870250104250, dated 11 / 14 / 2025, page 8 / 21 / 8 interrupt operation to prevent damage. The self-diagnostic system issues alerts about the need for preventive maintenance.

[012] The silage baling and packaging machine features operational functioning with forage feeding, where the material is inserted into the automatic conveyor.

[013] For compaction in the pressing chamber, the forage is compressed into a cylindrical shape. This compacted cylinder is moved to the packaging unit, to be wrapped in plastic film, where the bale is rotated and wrapped automatically. The film is sealed and cut, completing the process.

[014] The machine improves forage preservation, preventing uncontrolled fermentation and reducing the proliferation of unwanted bacteria. It also preserves proteins and carbohydrates, ensuring balanced nutrition for the animals.

[015] It also reduces waste and maintains feed quality for longer periods. It enables the reduction of operational costs through automation, which reduces the need for labor. Automation results in less loss of stored forage, enables reduced logistics and transportation costs, generating greater storage efficiency. Optimized compaction ensures less space is needed to store large volumes, provides protection against climatic factors, as the plastic film prevents the entry of moisture and oxygen, and also facilitates transportation, since the standardized bales allow for safe stacking.

[016] The silage baling and packaging machine represents an innovative, economical and sustainable solution for Petition 870250104250, dated 11 / 14 / 2025, page 9 / 21 / 8 livestock farmers and agricultural producers who need high-quality silage, efficient storage, and reduced waste.

[017] With advanced technology, a robust structure, and a high-performance automated system, the machine stands out in the market for its efficiency, safety, and productive capacity, providing direct benefits in animal nutrition and agricultural logistics. DESCRIPTION
