Development of Tractor Mounted FYM Spreader

The application of FYM in the field is carried out traditionally lead to uneven distribution, increases cost and labour requirements. The developed machine consists of the manure tub, FYM conveyor unit, manure discharging gate, shredding and spreading unit. The conveyor unit passes FYM from manure tub in to the shredder unit with the help of belt conveyor through the manure discharge gate and manure discharge gate provided to change levels of opening from the bottom of conveyor belt. The shredding unit is mounted on the mainframe. Flexible chains are used as beating elements. The shredder collects FYM material from top surface further it directs to the openings designed in such way that the material is evenly spread on the field. The developed machine was evaluated for field performance with the optimized variables derived from the experimental trials is the conveyor speed, bulk density and clod size distribution. The optimized parameters were conveyor speed is 48 RPM, beating roller speed 255 rpm, bulk density and clod size distribution were observed as 0.503 g cm ⁻³ and 57.66% at 100 mm discharge gate opening with 4 chain links respectively. The discharge rate was 4.9 t/h at 100 mm manure discharge gate opening belt speed at 48 rpm.
