DESC:CROSS REFERENCE TO RELATED APPLICATION
This Application is based on and derives the benefit of Indian Provisional Application 202411017473 filed on 11th March 2024, the contents of which are incorporated herein by reference.
TECHNICAL FIELD
[001] Embodiments herein generally relates to agricultural sprayers and more particularly to the agricultural sprayer with oscillating spray nozzles.
BACKGROUND
[002] Agricultural sprayer is used to spray chemical agent and/or biological agent to the crops cultivated in a region to treat the disease in crops or to provide nutrition to the crops. A conventional agricultural sprayer mainly comprises a tank which is used to store any of chemical agent and/ or biological agent, a plurality of nozzles which are used to spray the chemical/biological agent to the crops, a boom for mounting the nozzles, and a mechanical pump which is usually driven by a power take-off shaft (PTO shaft) of a vehicle to pump any of chemical agent and/ or biological agent from the tank to the plurality of nozzles. Each nozzle of the conventional agricultural sprayer is a stationary nozzle that sprays any of chemical agent and/or biological agent in fixed directions thereby resulting in wastage of chemical agent and/or biological agent, increased cost for refilling chemical agent and/or biological agent in tank and also results in contamination of water, soil and air which is undesirable. Further, the conventional agricultural sprayer uses more number of nozzles which are adjusted manually for different crops thereby leading to operator’s discomfort. Furthermore, the conventional boom type agricultural sprayer may not have more stability in agricultural fields due to larger working width of the agricultural sprayer.
[003] Therefore, there exists a need for an agricultural sprayer which obviates the aforementioned drawbacks.

OBJECTS
[004] The principal object of embodiments herein is to provide an agricultural sprayer with oscillating spray nozzles.
[005] Another object of embodiments herein is to provide a compact agricultural sprayer which is lightweight and has reduced overall width when compared to the width of the conventional agricultural sprayers.
[006] Another object of embodiments herein is to provide the agricultural sprayer with lesser number of oscillating nozzles when compared to more number of stationary nozzles used in the conventional agricultural sprayers.
[007] Another object of embodiments herein is to provide the agricultural sprayer which reduces wastage of chemical agent and/or biological agent thereby reducing cost for refilling chemical agent and/or biological agent in tank.
[008] Another object of embodiments herein is to provide the agricultural sprayer which is cost-effective and has reduced weight.
[009] Another object of embodiments herein is to provide the agricultural sprayer which can work faster as well as spray for longer distance.
[0010] These and other objects of embodiments herein will be better appreciated and understood when considered in conjunction with following description and accompanying drawings. It should be understood, however, that the following descriptions, while indicating embodiments and numerous specific details thereof, are given by way of illustration and not of limitation.

The nozzle mounting bracket assembly (106A) of each nozzle mounting assembly (106) is adapted to facilitate mounting of the corresponding oscillating spray nozzle (104) thereon via the corresponding nozzle retainer assembly (106B). The nozzle mounting bracket assembly (106A) of each nozzle mounting assembly (106) includes a first mounting bracket (106AF) and a second mounting bracket (106AS). The first mounting bracket (106AF) is mounted onto a top end of the nozzle oscillating shaft (106C). The second mounting bracket (106AS) is pivotably connected to the first mounting bracket (106AF) through a pair of pivot pin joints (106J) (only one of which is shown in figs. 3A, 4A and 4B). The fastener (106F) of the nozzle mounting bracket assembly (106A) of each nozzle mounting assembly (106) is adapted to secure the corresponding second mounting bracket (106AS) with the corresponding first mounting bracket (106AF). The second mounting bracket (106AS) of each nozzle mounting assembly (106) is adapted to mount the corresponding nozzle retainer assembly (106B) therein to facilitate mounting of the corresponding oscillating spray nozzle (104) thereon.

For the purpose of this description and ease of understanding, the power transmission unit (112) is considered to be a reduction speed gearbox.
[0029] The technical advantages of the agricultural sprayer (100) are as follows. The agricultural sprayer is compact and lightweight and has reduced overall width when compared to conventional agricultural sprayers. The agricultural sprayer has lesser number of oscillating nozzles when compared to more number of stationary nozzles used in conventional agricultural sprayers. The agricultural sprayer reduces wastage of chemical agent and/or biological agent thereby reducing cost for refilling chemical agent and/or biological agent in tank. The agricultural sprayer is cost-effective and has reduced weight. The agricultural sprayer can work faster as well as spray for longer distance.
