Abstract:

Manual harvesting of paddy is more time consuming and has become a costly operation. Hence there is a need for mechanization of harvesting, at present the available machinery for harvesting are large in size and expensive and are not reaching the small scale farmers. The rotary type cutting mechanism has been developed with the proper transmission system by using the knapsack power sprayer engine as a prime source. This entire equipment can be utilized as a multipurpose for both operations separately as a sprayer and as a paddy harvester. In this study the engine of 1.64 kW with rated RPM of 5600 has been selected and calculated the flexible shaft diameter as a 16mm and to reach the required rpm of the cutter shaft. The transmission system with bevel gear of reduction of 1:2 has been designed. The trapezoidal shape of blades with serrations have been designed with the height of cut was 25 mm. the rotary cutter diameter has been designed 300 mm with the peripheral speed of 60 m/s for cereal crops. The overall transmission efficiency of the machine with input speed of 4800 with output speed at cutter shaft is achieved 75%. The theoretical field capacity of the paddy harvester has been achieved as 0.082 ha/h.
