Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery, in particular to a taro harvester. Background Art

[0002] Taro, also known as taro or taro, is an underground corm of the Araceae family. Its shape and texture vary depending on the species, and small taro is usually edible. It is a perennial tuberous plant, often cultivated as an annual crop. The leaves are shield-shaped, with long and thick petioles, green or purple-red. A shortened stem is formed at the base of the plant, which gradually accumulates nutrients and grows into a fleshy corm, called "taro" or "mother taro", which is spherical, ovate, elliptical or blocky. Each node of the mother taro has a brain bud, but the axillary buds at the middle and lower nodes are the most active, and the first tillering occurs, forming a small corm called "son taro", and then "grandson taro" occurs from the son taro. Under suitable conditions, great-grandson or great-great-grandson taro can be formed.

[0003] Since taro tubers are buried in the soil, the traditional method of harvesting is to manually use a hoe to dig the soil around the taro, and eventually lift up the entire taro tuber to complete the taro harvest. However, with the progress of agricultural modernization, the amount of taro cultivation has been expanding, and the efficiency of manual harvesting cannot keep up with the increase in the number of plantings, and the labor cost is getting higher and higher.
