DESC:TECHNICAL FIELD
[1] The present invention relates to agricultural spraying systems and, more particularly, to a semi-automatic, self-propelled spraying apparatus equipped with an asymmetric container and efficient suction and nozzle systems for optimized fluid utilization in diverse field conditions. The present application is based on and claims priority from Indian Application Number 202421051443 filed on 2024/07/04, the disclosure of which is hereby incorporated by reference herein.
BACKGROUND
[2] In prior-arts, various types of liquid chemical spraying apparatus used for agriculture are known.
[3] JP3161267U discloses a wheeled chemical spraying apparatus with container of rectangular shape placed on a frame such that container is placed on frame in upright or vertical position. The container is of symmetrical shape and configuration which has a limitation of effective utilization of spraying material from the container. Nozzle unit disclosed in the captioned prior-art is hand held single nozzle rod which has limitation of spraying for large and medium sized fields or farms.
[4] KR101469661B1 discloses a wheeled chemical spraying apparatus with container of rectangular shaped placed on a frame such that container is placed on the frame in horizontal position. Further, nozzle assembly is placed vertical rod which is adjustable in height or width hence not suitable for large or medium size farm spraying.
[5] Hence, known prior-arts have problem of incomplete utilization of the spraying liquid due to rectangular or symmetrical shaped container designs. Further, the nozzle assembly disclosed in the prior-arts are not adjustable to accommodate large size and medium size farm spraying needs.
[6] Furthermore, agricultural spraying operations traditionally involve manually operated or towed systems that offer limited fluid utilization and agriculture field coverage. Most existing sprayers lack an efficient container design to ensure full fluid discharge and are not optimized for terrain adaptability or ergonomic operation. These systems may not adapt well to varied terrains or crop heights and frequently require significant labor input, leading to increased operational time and cost. These limitations result in wasted resources, operator fatigue, and increased time per acre. There is thus a need for a mobile, self-propelled, semi-automatic agriculture spraying apparatus with enhanced spray control, complete fluid usage, and terrain adaptability.

STATEMENT OF THE DISCLOSURE
[7] An aspect of the present disclosure is to provide an agricultural spraying apparatus comprising an asymmetrical container configured for efficient suction and utilization of spraying fluid. The asymmetric container includes a downwardly extending protrusion on a first side and a nozzle assembly point on a second side of the asymmetrical container. A sloped portion between the first and the second side of the asymmetric container facilitates gravitational flow of residual spraying fluid from the nozzle side toward the protrusion portion of said asymmetric container. A suction assembly positioned at the protrusion portion enables effective extraction of the remaining fluid, thereby minimizing fluid retention and enhancing the complete utilization of the spraying material.
