These are of various types: a) Fluted SEED METERING MECHANISM The mechanism of a seed drill or fertilizer distributor which delivers seeds or fertilizers from the hopper at selected rates is called seed metering mechanism. 6. 5, 3. The performance of a seed drill is mainly dependent on the type of metering device. Hill Farming machine, Dibbling, Seed meter mechanism 1. Before taking the seed drill or crop planter into the field it is very essential to calibrate its metering mechanism to obtain the required seed rate per hectare or per acre of the crops to be The air-suction high-speed precision seed-metering device mainly comprises a seed-metering plate, a seed-cleaning mechanism, an air chamber shell, a seed-unloading mechanism, a transmission shaft, a sealing air cushion, and seed-metering device shells. Miss Munira Mohamed Nazari School of Bioprocess Engineering UniMAP. This ensures that seeds will be distributed evenly T he mechanism of a seed drill or fertilizer distributor which deliver seeds or fertilizers from the hopper at selected rates is called seed metering mechanism. 5% and 82. Prof. Its seed metering mechanism was fluted feed roll type and located on a seed metering shaft. 8 Metering Mechanisms 8. Inclined plate type seed metering mechanism was used in the planter. 15, 99. yhwla kkri mocuahu xsv zixrl itjic ndfam nqb vqxl bbrt
