3.3.3 Driving wheel
A wheel of 600mm diameter was used. The wheel was attached to a sprocket gear having 15 tooth and small sprocket gear having 13 tooth and both were connected with chain. A crank was used for receiving motion from the chain
3.3.4 Crank mechanism
A crank mechanism was used to convert the rotary motion from driving sprocket to reciprocating motion of the piston for operating the single wheel driven boom sprayer.
The crank mechanism is represented as shown below

ABSRACT - [ Total Page(s): 1 ]ABSTRACTThe single wheel driven boom sprayer was developed, fabricated and evaluated for its performance at the department of Agricultural and Bio-environmental engineering workshop, Kwara state polytechnic, Ilorin. The spraying performance was carried out at spraying height of 0.5m, 0.6m and 0.7m respectively. The theoretical field capacity CT, the effective field capacity CE and Field efficiency (Å‹) at spraying height of 0.5m are 0.285ha/hr , 0.165ha/hr and 58%, while at spraying hei ...

CHAPTER ONE - [ Total Page(s): 2 ]CHAPTER ONE1.0   IntroductionCrop yield is reduced by mainly due to attack of pest, diseases and weeds. Chemical control is the popular method adopted for controlling most insects, weed and diseases. The chemical are applied either by spraying or dusting. Spraying is one of the most effective and efficient techniques for applying small volume of spray liquid to protect crops. In conventional methods, manually operated low and high volume hydraulic sprayer and power operated hydraulic s ...

CHAPTER TWO - [ Total Page(s): 9 ]   Centrifugal energy sprayers: In the centrifugal energy sprayer the spray fluid is fed under low pressure at the center of a high speed rotating device such as flat, concave or convex disc. Spray is atomized by centrifugal force as it leaves the periphery of the atomizer. The droplets are carried by the air stream generated by the blower of the sprayer or by prevailing wind, if the sprayer is not provided with a fan.Kinetic energy sprayers: In kinetic energy sprayer the spray fluid ...
