Abstract
The invention relates to the technical field of harvesting and planting machinery for agricultural products, in particular relates to a Chinese yam harvesting and planting dual-purpose machine. The soil requires to be loosened deeply before the planting of long-rootstock crops; because the crops grow deeply in the soil and especially the growing situations of Chinese yam, burdock and the like are difficultly known, most of the crops are harvested manually so as to avoid damage of the crops during the harvesting, and thus the labour intensity is high and the work efficiency is low. The technical scheme of the Chinese yam harvesting and planting dual-purpose machine disclosed by the invention is characterized by comprising a frame, a power device and a furrowing device; the upper end of a shaft sleeve of a vibrating device is assembled at the rear part of the furrowing device, and the lower end of the shaft sleeve of the vibrating device is fixedly provided with a wedge-shaped vibrating box. During the harvesting of the crops such as Chinese yams and the like, the soil at two sides of a crop ridge is dug to be loose by using the furrowing device, then the soil below or around the crop is vibrated to be loose by using the vibrating device, and finally, the crop is ejected upwards, so that the intactness of the crop in the digging process is guaranteed and the work efficiency is improved greatly. The Chinese yam harvesting and planting dual-purpose machine further can be used for digging the soil to be loose by only using the furrowing device and improves the planting efficiency of the agricultural crops.
