| Abstract: |
| Given the unwanted large holes on film surface with basket-type planting devices during above-film hole-forming device, and establishing a motion model of the planting mechanism, we analyzed the trajectory characteristics of the planter. It was found that when the trajectory of the planter was the trochoidal line, the distance of the maximum transverse chord of the trochoidal ring buckle was equal to the distance between the intersection of the trajectory line and the film, and the planter was opened in the uplifting stage. It was beneficial to reduce the size of the membrane face. Through simulation analysis and transplanting of tomato seedlings on the film, it was concluded that the trajectory characteristic coefficient, λ, had a significant influence on the longitudinal dimension of hole on the film, the transverse dimension and inclination rate were not obvious. As the λ value increased, the longitudinal dimension of the hole first decreased and then increased. When the transplanting frequency was 50 and 55 plants·min-1, and the λ was 1.093, the longitudinal dimension of the hole was 10.12 and 9.49 cm, respectively, which was the minimum value. Under the two transplanting frequency conditions, as the λ value increased, the transplanting plant distance decreased from 39.8 cm to 33.5 cm and from 39.1 cm to 33.1 cm, respectively. This conclusion can be used to guide the optimization of the structure and working parameters of the basket-type transplanter. |
