Description

Technical Field

[0002] Vegetables contain a variety of nutrients needed by the human body. Some of the nutrients in vegetables can effectively prevent diseases. With the improvement of living standards, people pay more attention to the intake of vegetables, and the market demand for different varieties of vegetables is also growing. my country is now the world's largest vegetable production base, with the world's largest vegetable output and planting area.

[0003] At present, semi-automatic transplanting machines are mainly used in China, and manual labor is still required to take the seedlings out of the hole tray and put them into the planter, and then the planter will plant the seedlings into the field. The transplanting efficiency is between 800 and 1,000 plants per hour, and the manual labor intensity is high and the efficiency is low.

[0004] my country started late in designing transplanters, and there are many problems. my country's infrastructure is relatively backward, and it has not formed a unique industrial chain. Problems are prone to occur in a certain link during the production process, which greatly restricts the development of transplanters. The transplanter models developed in my country are mainly based on imitations of more mature foreign models, and have not formed their own characteristics. The transplanter models developed abroad do not conform to the actual situation of my country's agriculture in some aspects. There is still a big gap between the agronomic level at home and abroad, and the standards and requirements of the production links are not the same. The transplanters developed in my country at this stage have low precision, poor versatility, complex operation, and single specifications, which are not suitable for multiple crop operations. my country's large land area and diverse landforms have led to different crop production standards in various regions, which cannot be unified, so any model of machinery cannot be applied to production in various regions.
