BR-202020002278-Y1 - CONFIGURATION APPLIED TO A SPRAYER ATTACHED TO AGRICULTURAL IMPLEMENTS FOR SOIL PREPARATION

Abstract

CONFIGURATION APPLIED IN A SPRAYER ATTACHED TO AGRICULTURAL IMPLEMENTS FOR SOIL PREPARATION. This utility model application generally pertains to the agricultural machinery and implements sector and refers more specifically to a new constructive arrangement for a pesticide sprayer mounted on soil preparation implements such as subsoilers, subsoiler plows, decompactors, scarifiers, among others, whether attached or towed. The model consists of the assembly (1) mounted on a main chassis (1.2), a mounted spray bar (2) and an access/operation ladder (3). The utility model, in general, describes a complete spraying unit attachable to soil preparation implements such as subsoilers, scarifiers, etc., with the objective of desiccating the field or distributing liquid fertilizers on the soil surface simultaneously with the soil decompaction and preparation process before no-till planting, thus reducing the need for time, labor, fuel and various inputs, optimizing operational windows.

Description

Technological sector of the model [001] This utility model application generally pertains to the agricultural machinery and implements sector and refers more specifically to a new constructive arrangement for a pesticide sprayer mounted on a soil preparation implement such as subsoilers, subsoiler plows, decompactors, scarifiers, among others, whether coupled or towed. Known state of the art [002] Currently, the most widely used grain cultivation method in Brazil is no-till farming. This method does not involve tilling the soil, thus keeping its surface intact and only planting the new crop over the residues of the previous harvest. These crop residues are of great importance for the success of the newly planted crop, so that, in some cases, cover crops are applied in order to provide an increase in organic matter cover. [003] In any of the above cases, with or without cover crops, and considering that this method does not involve soil disturbance, all pre-existing living plants remain in the soil, whether weeds, volunteer plants, or cover crops. Such living plants or green vegetation, when in large quantities, can cause problems at the time of planting the new crop, the main ones being clogging or accumulation of plants in the seed hoppers, difficulty in depositing the seed and/or fertilizer in the correct location, and damage to the development of the new crop due to competition for nutrients and sunlight. [004] That said, it is very common to carry out chemical desiccation of any living plant in the field before planting the new crop; this desiccation is characterized by the spraying operation carried out using implements driven by tractors or self-propelled equipment; in either case, this operation is characterized as an additional operation. [005] Similarly, due to the basic characteristic of no-till farming of not using traditional prior soil preparation, over the years there is a progressive formation and evolution of a compacted layer immediately below the depth commonly practiced in planting operations. This compacted layer hinders the advancement of crop roots and their consequent access to water and nutrient reserves, increases fertilizer loss through washing and leaching, and ultimately produces severe soil erosion. [006] To combat soil compaction problems, agricultural implements with low surface disturbance, such as subsoilers and scarifiers, are used in soil preparation. The decompaction operation essentially takes place before planting a new crop. New features and advantages of the model. [007] The utility model in question has the main objective of reducing the number of field operations by combining soil decompaction with desiccation, thus reducing the need for field interventions and, consequently, generating savings in time, labor and fuel, thereby optimizing the pre-planting operational window and the cultivation of multiple crops throughout the year. [008] The utility model in question provides for the assembly of a complete surface spraying system on soil preparation equipment using existing propulsion and drive means on the tractor machine with virtually no increase in power required for the combined operation. Brief description of the model [009] The present utility model consists of a complete surface spraying system attached to soil preparation implements comprising a spray tank; adapter chassis; hydraulic system composed of an orbital hydraulic motor and peripherals; spray pump; spray control unit with flow regulator; spray boom; and spray nozzles. The spray tank is positioned on the adapter chassis, and similarly, the hydraulic motor, spray pump, and spray control unit are attached to the adapter chassis, which is mechanically attached to the chassis of the soil preparation implement. The spray nozzles are attached to the spray boom, which in turn is mechanically attached to the chassis of the soil preparation implement, so that it is located at the rear end of the soil preparation implement, covering the available working width. Brief description of the figures [010] In order for the present model to be fully understood, differentiated and functional, it will be described clearly, concisely and sufficiently through the figures listed below: [011] Figures 1, 2 and 3: Perspective views illustrating the main items of the configuration; [012] Figures 4 and 5: Perspective views illustrating the items referred to as the assembly mounted on a main chassis and spray bar; [013] Figures 6 and 7: Perspective view and left side view illustrating the configuration coupled to a soil preparation implement; [014] Figures 8 and 9: Perspective and left side view illustrating the complete configuration coupled to a soil preparation implement - scarifier. Detailed description of the model [015] As can be seen in Figures 1, 2 and 3, the model consists of the assembly (1) mounted on a main chassis (1.2), a spray bar (2) mounted and an access/operation ladder (3).
