Fabrication and Evaluation of a Metering Device for a Sugarcane Billet Planter

Ölçüm cihazı, toprak yüzeyinde tohumların veya çeliklerin kesin sayım ve bir örnek dağıtımındansorumlu olan herhangi bir ekici-dikicinin en önemli parçasıdır. Bu araştırmada yeni bir ölçüm ünitesi,şeker kamışı çelik dikim aleti için tasarlanmış ve imal edilmiştir. Prototip, esas dikim karıkları yüzeyineçelik taşınması için bazı tutma dolabı ile sonsuz bir zincir konveyörden oluşmaktadır. Bu zincirlikonveyör sisteminin etkili ve verimli bir tasarımı, çubukların istenen bir örtüşme ve kesin zamanlama iledikilmesini sağlamaktadır. Sonuç olarak, filizlenmeden sonra daha muntazam bir ürün kaplanmasının eldeedilebilmektedir. Bir laboratuar test teçhizatı kullanarak, dikim hızı, şeker kamışı değişim ve dolaplarıyüzdesini doldurmasında zincir yapısının açısı, örtüşme ve dikili çelik altında örtüşme etkilerideğerlendirilmiştir. Testler için tamamen tesadüfî faktöriyel deneme deseni kullanılmıştır. Sonuçlara göre,tasarım ölçüm ünitesinin en iyi performansına, konveyör zinciri için 20º açı ve 3.5 km/h dikim hızıolduğu durumdadır.

Şeker Kamışı Çelik Dikim Aleti İçin Ölçüm Cihazı İmalatı ve Değerlendirilmesi

Metering device is the most important part of any planter that is responsible for precisecounting and uniform distributing the seeds or billets over ground surface. In this research a new meteringunit was designed and fabricated for sugarcane billet planter. The prototype is mainly consisted of anendless chain conveyor with some holding cupboard for conveying the billets to the surface of theplanting furrows. An effective and efficient design of this chain conveyor system enables it the precisetiming for the billet to be planted with desirable overlap. As result, a more uniform crop coverage can beachieved after sprouting. Using a laboratory test rig, the effects of planting speed, cane variety and angleof chain structure on filling percentage of the cupboards, overlapping and under overlapping of theplanted billets were evaluated. A factorial experiment in a completely randomized design was used for thetests. According to the results, the best performance of the design metering unit is found to be at plantingspeed of 3.5 km h-1and 20º angle for conveyor chain.
