The Study of Cassava Root Conveying Equipment Attached to a Truck

摘要

The objective of this study was for development of cassava transporting equipment installed on a truck. The study process was divided into 2 steps: 1) The study of cassava harvesting and transporting to the truck pattern by farmers practice today and 2) preliminary study of transporting cassava by using additional conveying device in order to reduce time and labor for the overall harvest system. Results in step 1 indicated that the pattern of cassava harvesting consisted of four main steps : tillage, heap compiling, stem cutting and cassava transporting to the truck. The most time consuming step was the transporting of cassava to the truck. The cassava's transporting to the plant normally had to be completed within one day. The consequently, cassava transporting was considered to be the bottle-neck problem of cassava harvest system. Result from the study in step 2, which was preliminary study of using a conveying device attached to the truck to reduce time and labor indicated that a working capacity of 1.44 rai/hour was obtained, being 3.13 time higher than the usual manual labor method.
