1. DESIGN AND CONSTRUCTION OF MANUALLY OPERATED PESTICIDE SPRAY PUMP By Chandiga Richard Enrique 20/1/335/D/319 Kalimbaza Eric 20/1/335/D/622 Supervised by Mr. Mpiima Isaac Ms. Atto Gloria 12/12/2023 1

2. Background Agriculture is the backbone of Ugandan economy . (Bamwesigye et al., 2020) Insects are largely responsible for crop destruction . (Ebregt et al., 2005) The use of pesticide is still increasing on control of pests . (Jalu et al., 2023). The argument for using a conventional sprayer includes; This research proposes for a design and construction of manually operated pesticide spray pump. 12/12/2023 2

3. Problem statement S mall scale farmers use conventional spray pump to control pests Hand operated pesticide spray pump Motorized back pesticide spray pump This research proposes for design and construction of manually operated pesticide spray pump. 12/12/2023 3

4. Main Objective To design and construct a manually operated pesticide spray pump. Specific Objectives The specific objectives of this study will be; To construct the various components of the spray pump. To fabricate the spray pump. To test the spray pump. 12/12/2023 4

5. Justification of study Wheel-driven sprayers will be cost-effective compared to traditional methods of spraying since they will require less labor and will not consume fuel, which will result in a lower operational cost. Their cost-effectiveness will ensure that farmers maintain profit while keeping production costs low. Wheel-driven sprayers will cover a larger area in a short time compared to hand operated spray pump. This will save time that will allow farmers to complete spraying operations quickly and effectively. 12/12/2023 5

6. Scope of study This research will be limited to the design and construction of manually operated pesticide spray pump which will use the principles of motion of wheel which will transmit its rotary motion from chain and sprocket arrangement and reciprocating piston into the cylinder for pumping the pesticides . This will be used by small scale farmers for short crops with fair spacing planted on relatively flat land. 12/12/2023 6

8. Methodology Research Design Qualitative design Quantitative design Design capacity The final design will have a standard 20litre knapsack tank to hold the pesticides Data collection methods Primary sources Secondary sources 12/12/2023 8

9. Methodology( continued) Data analysis and interpretation Material selection This will include weldabillity, ductility, malleability, corrosive resistance ability. Description of the manually operated pesticide spray pump . The components of the wheel spray pump will be a main frame, tank, wheel, driving and driven sprockets, boom assembly, nozzle, chain, piston pump, hose, shaft, Plummer block bearing and connecting rod. This wheel operated pesticide spray pump will use crank mechanism with piston pump, which will be driven by moving the wheel . The system will be framed with steel and painted to prevent rusting. It will be joined by bolts and nuts in order to ease assembling and disassembling the spray pump. 12/12/2023 9

10. Methodology(continued) Angular velocity of the wheel ( = where; v is the velocity and r is the radius of the wheel   Design analysis Actual Field Capacity of the Spray pump Actual Field Capacity = where; A will be area covered in ha and Total Time Taken = time of refilling the tanks + time of turning + time of actual work   12/12/2023 10

11. Methodology(continued) The theoretical field capacity Theoretical Field Capacity = Where speed (km/ hr )= wheel diameter (cm)*operator’s speed (rpm)   Field efficiency Field efficiency = 100 Total force required Total force required= Where; F=force, µ=coefficient of friction for mud and W= total load on the complete assembly   12/12/2023 11

12. Discharge Discharge is defined as the volume of water flows or rate of water flow through given cross sectional area is called as discharge. Discharge=Area of piston× stroke length× r.p.s Q= π/4 ( *L) r.p.s Total discharge Q= Q 1 +Q 2 +Q 3 +Q 4 Given that all the dimension ( diameter and length) of the nozzles are the same Where d 1 =d 2 =d 3 =d 4 Q 1 =Q 2 =Q 3 =Q 4 = Q/4   Methodology(continued) 12/12/2023 12
