Popis: A tractor-mounted cabbage collection system is under development to improve the mechanization rate of dryland crop production. The design of the cabbage-transportation part of a tractor-mounted Chinese cabbage collector is crucial for minimizing cabbage losses and for effective operation. Investigation of the effects of design parameters is useful to provide guidelines to fabricate the mechanism efficiently. Therefore, the present study aimed to conduct kinematic analysis of the cabbage-transportation part for optimum design of the Chinese cabbage collector. The conceptual design of the Chinese cabbage collector mainly consists of the cabbage transportation, packaging, and unloading parts. Kinematic analysis of the cabbage-transportation part was conducted to investigate the effects of link lengths on the position, velocity, and acceleration of the mechanism. The performance of the cabbage-transportation part was simulated using a commercial software. The simulations were carried out using several cabbage sizes, cabbage transfer speeds, and link sizes at different locations on the cabbage-transportation part. The kinematic modeling and analytical procedure of the cabbage-transportation part were analyzed using mathematical models. The successful transfer of cabbage through the conveyor belt was influenced by the width of the cabbage-transportation part, cabbage size, and feeding speed. Consequently, some combinations of link lengths were not acceptable to convey the cabbages with the increase in the width of the transportation part. On the contrary, interferences between the links occurred with the decrease in the width of the transportation part. The simulated results showed that greater transferring speeds of cabbage increased the kinematic values, causing damage to the cabbages. The recommended and effective cabbage transferring speed, the length of the link, and the width of the transportation part were found to be 0.2 m/s, 190 to 200 mm, and 500 to 600 mm, respectively. This study is useful for the design of an efficient cabbage-transportation part, and suitable improvements to the fabrication of the Chinese cabbage collector prototype.
