Background

Rhizoma Dioscoreae, also known as Dioscorea opposita and Dioscorea alata, belongs to Dioscoreaceae, and is served by its enlarged root tuber or cylindrical root. In order to ensure the high yield of the Chinese yam, sandy loam with loose soil, high and dry topography, deep and fertile soil layer, convenient irrigation and drainage, good permeability and water retention is selected in the Chinese yam land, and the Chinese yam sprouts at the ground temperature of about 10 ℃, so that the Chinese yam is in a proper planting period when the average temperature of an underground planting layer rises to 10 ℃, and planting furrows need to be dug in the Chinese yam land at the moment.

The length of the Chinese yam is different according to the variety of the Chinese yam, the depth of the planting groove is generally 15-20 cm, the labor intensity is high due to the fact that only manual ditching is needed, and if the portable soil aerator shown in Chinese patent application No. 200820122620.2 is used for manual ditching, only one planting groove can be dug at a time, and the efficiency is low. In order to improve the ditching efficiency, a mechanical device capable of continuously ditching needs to be developed, wherein how a rotary driving device of a drill bit automatically ascends and descends along with a lifting system at the same time is a key point and a difficult point in the development process.

When the lifting seat is located at the initial position, the pressure spring of the second support rod assembly is in an extended state, when the lifting seat descends, the first support rod rotates anticlockwise by taking a hinged point of the first support rod, which is hinged on the rack, as the center of a circle, the second support rod assembly is subjected to the pressure from the first support rod, and the pressure spring is compressed until the drill bit reaches a preset depth; when the drill bit rises along with the lifting seat, as shown in fig. 1, the first supporting rod rotates clockwise by taking a hinged point of the first supporting rod hinged on the rack as a circle center, and the pressure spring resets.
