Abstract

Aimed at solving the problem of the incidence of large film-breaking holes in the current sweet potato boat-bottom-shaped transplant, a boat-bottom-shaped up-film transplanting device was designed. Starting from the agronomic requirements of sweet potato up-film transplanting with a boat-bottom posture, an arc-shaped gripping mechanism was designed. In order to avoid further tearing and breaking the film hole during the movement of the clamping mechanism under the membrane, a transposition mechanism and a positioning cam were designed to jointly control the movement of the clamping mechanism. In order to ensure the stability of the transplanting plant spacing during the operation of the machine, a rotary encoder was used to collect the forward speed of the machine and adjust the speed of the power shaft in real time. Field experiments were carried out in order to verify the reliability and stability of the operation of the above-mentioned design mechanism. In the field test, the advance speed was used as the test factor, and the test indexes included three indexes of the seedlings after transplanting and three indexes of the film holes. The test results showed that the qualified rate of node depth in the middle of the seedling (QRNDMS) is between 95.67% and 86.79%, the qualified rate of root depth at the base of the seedlings (QRRDS) is between 94.00% and 90.11%, and the qualified rate of seedling length into the soil (QRSLS) is between 97.89% and 91.67%. The film hole spacing is between 240.33 mm and 245.32 mm, the film hole length is between 37.01 mm and 42.10 mm, and the film hole length variation rate is between 1.05% and 7.48%. This study can serve as a reference for up-film transplantation, particularly for boat-bottom-shaped up-film transplantation devices.
