Description

A galangal digging harvester with a disc cutter

technical field

The invention relates to a galangal harvesting device, in particular to a galangal digging and harvesting machine with a disc cutter.

Background technique

Galangal, also known as galangal, galangal, etc., is an evergreen perennial herb of the genus Zingiberaceae. Galangal likes a warm and humid climate, resistant to drought, waterlogging, and frost-resistant. It is native to the tropical and subtropical regions of South my country, and is now mainly distributed in Guangdong, Hainan, Guangxi, Yunnan and other regions in my country, of which Guangdong Xuwen County, Zhanjiang City, is the main production area of galangal. The planting volume is about 60,000 mu, the highest planting volume reaches about 100,000 mu, and the output accounts for more than 90% of the country. Propagation, general planting 3-6 years can be harvested. The current production and agronomic mode mainly adopts digging holes or opening shallow trenches for planting. Generally, the spacing between plants is about 35-50cm, and the row spacing is about 70-80cm. The field production process of galangal mainly includes plowing, planting, field management, and harvesting. At present, apart from plowing and land preparation, the planting of galangal, field management (weeding, fertilization, etc.), harvesting and other links basically rely on manual work. Especially the harvesting link requires a lot of labor. The harvest of galangal is mainly to harvest the underground galangal root. The galangal root is generally located at a depth of about 40cm below the ground surface after maturity, and the growth depth is deeper than that of general underground root crops. At the same time, the soil is compacted or compacted due to the growth of galangal for many years. Harvesting labor costs about 4,000 yuan per mu. At present, the lack of mature and available galangal harvesting equipment has seriously restricted the growth and development of the galangal industry.
