Abstract
Harvesting and transporting belong to the heaviest work in vinyl house. The mono-crawler cart was therefore made experimentally which is a ground-run type transporter, for the reduction of labour and the examination of possibility and the propulsion of the mechanization. The mechanism and performance of this cart is summarized as follows.
(1) The crawler was adopted which is suited for running on the narrow path and getting over the heating pipes and others. The results of performance test showed that the power requirement for transporting the maximum load of 120kg was 200-240W at the speed of 20-25cm/s.
(2) The field efficiency was 40-55%.
(3) The performance of harvesting and transporting green pepper was worse a little than the customary working (manual) in the working time per unit yield, but was improved remarkably in the transporting distance per unit yield.
(4) The improvement of the working and operating performance may be accomplished by rebuilding this model to the small size and light weight battery-car, in future.
