Hence there has been proposed to produce corn silage as forage alternatives. The quality of bag corn silage is stable and long-term preservable. But the bag corn silage is packed in factory, so the corn can''t be packed immediately after harvested. And its packaging operation requires extra labor cost. Therefore, in order to improve those defects, National Chung Hsing University designed an automatic mobile packing system. However, the system has no suitable packaging container and feeding system, so the objectives of this study are to design a corn silage barrel with automatic capping devices, and to design a feeding system associated with a swinging motion.
The design of corn silage barrel and feeding system are completed in this study, the capacity of barrel is about 28.55 liters. After packing corns of 20 kg, the silage density is about 0.70 g/cm^3. The design of lid facilitates an easy opening and capping mechanism using the sliding latch. Then, this study applies the finite element method using commercially available analysis software, ANSYS, to analyze the barrel, and the results show that the safety factor of barrel and related parts are all above 1.5. In addition, the automatic capping devices have been tested by a prototype of corn silage packing machine. Testing results greatly increase the possibility of using the lid. This study completes the design of a feeding system as well. The feeding system implements a discharge port using swinging movement associated with a swing rod connected with gear mechanism. The swinging mechanism is able to use the conveyor''s power directly.
