Design and Fabrication of a Multifunctional Punch Planter with the Capability of Performing Four Planting Steps in a Single Pass
摘要
This research aimed to design, fabricate, and evaluate a multifunctional machine for cucumber cultivation, capable of simultaneously applying animal manure fertilizer, forming ridges, installing drip tape, laying plastic mulch, piercing the mulch film, and planting seeds.
MethodsThe designed machine features an integrated chassis, a manure tank with an internal agitator, a mechanical power transmission system, a roller-based seed metering mechanism, and a reciprocating puncher. To assess its performance under field conditions, key indices such as the Miss Index (Mind) and Damage Index (Dind) were evaluated. The punch planter's performance was tested at three forward speeds (1, 2, and 3 km/h), two planting depths (2 and 4 cm), and two seed planting modes: two seeds per hole (Nh2) and three seeds per hole (Nh3). Additionally, this machine allows for precise adjustment of seed intervals between 17 to 25 cm, ensuring flexibility to accommodate different planting requirements and optimize crop spacing.
ResultsThe results indicated that forward speed significantly affected the seed damage and miss indices in the Nh3 mode, whereas no significant effect was observed in the Nh2 mode. Similarly, planting depth had no statistically significant impact on these indices in either mode. The final evaluation suggested an optimal forward speed of 2 km/h for the Nh2 mode and 1 km/h for the Nh3 mode, ensuring improved planting accuracy and reduced seed loss.
ConclusionsBy integrating multiple operations into a single pass, this machine minimizes soil structure damage, reduces costs and labor time, and represents a significant step toward sustainable agriculture. Overall, the findings demonstrate that the proposed simple and cost-effective mechanism ensures precise cucumber seed planting under real-world conditions, offering a viable alternative to existing punching mechanisms.
