Description

A kind of yam seeder

technical field

The utility model relates to an agricultural mechanical equipment, in particular to a yam seeder.

Background technique

After the 1990s, my country's yam planting area, yield per unit area, and total output have all increased significantly. The planting area is more than 250,000 hectares, and the annual output is more than 5 million tons. It is the country with the largest planting area and consumption of yam. However, the mechanized planting of yam is still relatively backward at present, mainly relying on artificial planting, and the production efficiency is low. The level of my country's agricultural machinery operations continues to improve. Mechanized sowing and harvesting of the three major grain crops of wheat, rice and corn have basically been realized. There are already corresponding machines for loosening the soil and ditching yam, but there is no professional seeder for the key step of seeding. The overall mechanization degree of yam is still very low.

Yam is a product of underground tubers, and its planting requires a certain depth in the ground. In my country, its planting methods are mainly artificial shovel digging or mechanical digging, and manual seeding. This traditional planting method is very inefficient and time-consuming. This backward sowing method has greatly restricted the large-scale production and development of Chinese yam. The demand for the degree of mechanization of yam planting is increasing, and it is imminent to effectively solve the problem of yam planting mechanization. The yam seeder is a high-efficiency operating machine that uses mechanization to realize the sequential sowing of yams. It uses tractor traction and hangs the seeder behind it to realize manual seeding to machine automatic seeding, which can greatly improve seeding efficiency and reduce labor costs. At the same time, it can release a large amount of agricultural labor. The development of yam seeder plays an extremely important role in adjusting and optimizing the agricultural industrial structure and accelerating the pace of increasing farmers' production and income.

At present, my country is still in a relatively backward state in the development of yam seeders. The mechanization level of yam seeding is not high. Most of the operations are manual or partially mechanized, and a large amount of manual labor is still required. Based on comprehensive considerations, it is extremely important to develop a planter that can effectively solve the problem of yam sowing, and is economical and suitable for the majority of farmers.
