Elastic chain belt type guide sleeve

An elastic chain belt type guide sleeve is characterized in that a plurality of outer sleeves are connected in series into a whole through an elastic chain belt, a guide sleeve with one closed end is slidably sleeved in each outer sleeve, each guide sleeve is blocked in the corresponding outer sleeve through a flexible stop dog, small sections of Chinese yam tubers are loaded into the guide sleeves, and the small sections of Chinese yam tubers are separated from each other under the pulling action of the elastic chain belt. Each outer sleeve transversely moves to sequentially correspond to a pushing hydraulic cylinder, a guide sleeve is ejected out of the outer sleeve through a piston rod, and the guide sleeve is obliquely inserted into soil, so that the Chinese yam is automatically and quickly planted, and the planting efficiency of the Chinese yam is greatly improved; the spacing between the outer sleeves can be adjusted according to the row spacing of Chinese yam planting, multiple pushing hydraulic cylind
