Description

Crop planting device for tractor towing The present invention relates to a tractor-towed crop transplanter that is towed by agricultural machinery such as a tractor to plant seedlings. Generally, vegetables (chili peppers, eggplants, cucumbers, etc.) and sweet potatoes are planted by transplanting seedlings, while root vegetables (potatoes) and ginger are cultivated by sowing rootstocks. The work process for sowing seedlings germinated in seedling pots or potatoes, etc., is carried out in a molded ridge covered with plastic film, consisting of the following steps: ① distribution of seedlings in seedling pots ⇒ ② perforation of the plastic ridge ⇒ ③ watering of the perforated ridge ⇒ ④ planting (sowing) of seedlings. This type of work requires a large workforce, but the rural areas where the work is taking place face a severe labor shortage due to reasons such as an aging population and population decline. Recently, various technologies related to planting machines are being developed and provided as patented technologies to address the decline in manpower caused by factors such as aging and population decrease in rural areas. Korean registered patent No. 10-2697420, 'Chain seedling supply unit for seedling transplanting device,' provides a technology in which chain seedlings, consisting of seedlings grown in a sausage shape connected by a connecting string, are separated one by one and supplied to a seedling transplanting unit for transplanting. Korean registered patent No. 10-0307388, 'Method and apparatus for transplanting onions,' provides a technology that enables accurate transplanting by configuring the transplanting method to strike the ground at regular intervals using a transplanting blade and drop the seedlings. Korean registered patent No. 10-1945853, titled 'Sweet Potato Transplanter and Driving Method Thereof,' provides a technology that enhances the price competitiveness of sweet potatoes by reducing labor, by being towed by a tractor and simultaneously transplanting multiple sweet potato seedlings onto ridges in a batch.
