The invention is specifically designed for use in agricultural machinery and spraying machines. The part relates to an arm made from profile steel. State of the Art Today, the boom structure in agricultural spraying machines allows for a wide range of pesticide nozzles. It is the most important structural element used to distribute the load across the area. Traditional boom Their designs are generally based on a single-piece or simple profile structure, and these structures can withstand a load of 15. Carrying capacity is limited. The advertising labels commonly used on agricultural spraying machines in current technology. (Boom / arm) are structural elements usually made of metal profiles (Figure 4a, 4b, 4c, 4d). These arms extend to both sides of the sprayer, applying pesticide evenly over a wide area. It provides spraying. Booms are generally of the fixed, hydraulically retractable, or telescopic type. It is designed with spray nozzles placed at specific intervals on the boom. Its structure varies depending on strength, weight, flexibility, and driving conditions. This indicates a risk of mechanical damage, transportation difficulties, and on-site collision situations. It may encounter repairability problems. These technical limitations, pest control 25 This can negatively impact performance, operator safety, and machine durability. In agricultural machinery (especially spraying machines), these types of profiles are related. The carrier arm is used as a boom or connecting arm that transports the drug. Multi-part profile. Due to their structure, their production is both challenging and involves high production costs. 30 Subsequent maintenance and repair costs are among the additional disadvantages. Also included in the current technology is the US10433535B2 "Agricultural Sprayer Boom". The patent, titled "Development of Boom Structure for Agricultural Spraying Machines," 2 It is directed towards agricultural applications.

No. US20190281807A1, “Sprayer or spreader bom structure and sprayer The patent titled "or spreader with such a boom" describes expanding the boom structure and making it lightweight. A 10 that facilitates the use of materials and maintenance / repair on assembled booms. It proposes a structural design. It aims to overcome the welded weaknesses of aluminum or alloy booms. Patent number US11974566B2, titled "Bom section for an agricultural machine," states: Faster and more flexible nozzle (spray nozzle) positioning on the boom. It offers a boom section structure that enables this; thus, different fields 15 Under these conditions, adjusting the boom and changing the nozzle sequence becomes easier. Figures 4a, 4b, 4c, and 4d show the joining of multi-part sheet metal profiles from the previous technique. The images show various handle structures obtained by welding, screwing, etc. As can be seen in Figures 4a, 4b, 4c, 4d; several 20s were used in the known state of the technique. Hair-based arm systems are actively used. In these, for strengthening purposes... The production process involves a laborious process involving auxiliary hair strands welded together. In conventional agricultural spraying machines, the lateral boom / arm structures are generally fixed or It consists of welded metal profiles. The joining of these profiles by welding takes 25 minutes to produce. This can lead to the emergence of residual stresses during this phase. These stresses can cause cracking or compromise the integrity of the weld during service. It increases the risk of deformation. In the welded boom units of the previous technique, shown in Figures 4a, 4b, 4c, and 4d, there were only 30 Even if an area is damaged, repair can often be difficult and costly; because The welded joint may need to be reworked or the part replaced. Additionally, Increased bending moment under long boom profiles causes fatigue in structural elements. This can lead to stress and ultimately breakage. These disadvantages are present. 3 boom designs' durability, ease of maintenance, and manufacturing efficiency These technical limitations necessitate a more robust, easy-to-repair, and structurally sound system. This highlights the need for boom designs with enhanced integrity. Purpose of the Invention The invention aims to eliminate the disadvantages inherent in the prior art. One purpose is to produce a single piece from a single profile, without welding, with less material and low labor costs. It is about ensuring production. Another purpose of the invention is to provide an additional welded frame for connection with the additional profile or The point is that no combination is needed. Another aim of the invention is to achieve high surface quality and production repeatability. The advantage is that the profile cross-section can be controlled by extrusion. 15 Another aim of the invention is to have fewer interconnections and therefore less maintenance. Thanks to the reduced number of parts, the need for maintenance decreases. Another purpose of the invention is to ensure low production costs. 20 Another aim of the invention is to ensure continuity in production. Another objective of the invention is to ensure smooth load transfer. Another purpose of the invention is to provide the advantage of low labor costs. Another purpose of the invention is to make the arm affordable for small farmers. It is the advantage it provides. Another purpose of the invention is to reduce the weight of the machine because the arm has less material. Its low cost offers an advantage when spraying agricultural products such as rice. 4 To provide the advantages mentioned above, the invention is used for agricultural machinery and spraying. for their machines, preferably with hinges on both sides that can be opened and closed; in a single piece.
