Abstract

This utility model belongs to the field of agricultural machinery and implements, more specifically, agricultural machinery and implements for distributing nutritional compost in animal breeding environments, whether confined or not. The present invention, in the nature of a utility model, presents as its main advantage over known devices in the prior art the fact that it possesses a load-damping system in the transverse arms, equipped with springs that interoperate with a shaft whose diameter is slightly smaller than the inner diameter of the spring. This causes the compression of the spring, very close to the shaft, to allow the spring coils themselves to act as perimeter wipers for the shaft. In this way, mechanical jams generated by the accumulation of feed between the spring coils and the respective shaft to which the spring is operatively associated are eliminated. This greatly reduces the number of operational stops for equipment maintenance.

Description

UTILITY MODEL FIELD [001] The present utility model belongs to the field of agricultural machinery and implements, more specifically, agricultural machinery and implements for distributing nutritional compost in animal breeding environments, whether confined or not. [002] The present invention, in the nature of a utility model, has as its main advantage in relation to devices known in the state of the art the fact that it has a load damping system in the transverse arms, equipped with helical springs that interoperate with a shaft with a diameter slightly smaller than the inner diameter of the spring. This causes the compression of the spring, very close to the shaft, to allow the spring links themselves to act as wipers of the shaft perimeter. [003] In this way, mechanical blocks generated by the accumulation of feed between the links of the helical spring and the respective shaft to which the spring is operatively associated are eliminated. This greatly reduces the number of operational stops for equipment maintenance. [004] The locking of the arms by the generation of mechanical wedges due to the accumulation of feed in the links of the compression springs in the longitudinal arms of the machine rotors is one of the main problems presented in the equipment known in the state of the art. SUMMARY OF THE UTILITY MODEL [005] Feed mixer wagons for use in agricultural environments are well known in the state of the art, being an essential piece of equipment for the efficient management of livestock feed, ensuring a homogeneous mixture of ingredients and the correct distribution of feed to the animals. This equipment is widely used on dairy and beef cattle farms and in other livestock operations, where precision in feed formulation and distribution directly impacts animal health and productivity. [006] In general terms, the mixer wagon is equipped with a chassis, constructed of steel beams or tubes, to act as a base for the other sub-assemblies. This chassis is constructed of high-strength steel to support the weight of the materials and resist wear caused by constant use. The chassis is mounted on a wheel system attachable to a tractor unit, such as a wheeled or tracked tractor, in a simple towing system or via hydraulic arms in a three-point hitch system, allowing the wagon to move around the farm. In some configurations, this equipment can be stationary. [007] Mounted on the chassis is a reservoir or cargo box, which is the compartment where the feed ingredients are loaded and mixed. It can have different capacities, depending on the wagon model and the specific needs of the livestock operation. The reservoir or cargo box is usually constructed of stainless steel or carbon steel with an anti-corrosion coating to prevent deterioration caused by moisture and the chemical components of the feed. Its shape can vary, but it is frequently cylindrical or trapezoidal, optimizing the mixing of the ingredients, since the material flows by gravity in these shapes. [008] These tanks or cargo boxes can be loaded in two ways: manually, with operators adding the ingredients directly to the tank, or automatically, using conveyors, such as milling systems located at the extreme portions to transfer the materials into the wagon. In some models, there are integrated scales that allow for precise weighing of the ingredients before mixing. [009] Inside the reservoir or cargo box, there is a mixing system. The mixing system of the mixer wagon includes the mixing arms operatively associated with the rotation shaft and the drive mechanism. This system is responsible for ensuring that the ingredients are mixed homogeneously, so that each portion of the feed has the same nutritional composition. [0010] These mixing systems are equipped with mixing arms, which are typically manufactured from high-strength steel, such as carbon steel or stainless steel. These materials are chosen for their durability and corrosion resistance, ensuring a long service life even under intensive use. In some applications, the arms may receive additional coatings of wear-resistant materials, such as tungsten carbide, to further increase their longevity. [0011] The geometry of the mixing arms varies according to the type of wagon and the mixing requirements. Some arms have angled paddles or propellers, designed to lift and turn materials, while others may have serrated knives or blades to cut whole bales of silage or other bulky ingredients. The angle and arrangement of the paddles are optimized to create the movement necessary for efficient mixing. [0012] The mixing arms are firmly coupled to the central shaft of the wagon, which is the component that transmits the engine power to the arms. This coupling is usually done through flanges or welded connections, ensuring that the arms rotate in sync with the shaft. In some models, the coupling may be adjustable, allowing the operator to change the position of the arms as needed for different types of mixing. [0
