Grab type yam seeder

Abstract

The invention relates to a grabbing Chinese yam seeder, which comprises a seeding mechanism, wherein the seeding mechanism comprises a crank-link mechanism and a mechanical arm; a crank in the crank-link mechanism is rotationally connected to an output shaft; the connecting rod is connected with the mechanical arm; the mechanical arm comprises a connecting rod, a slideway and a grabbing arm; one end of the connecting d is hinged to a connecting link in the crank-link mechanism and the other end is fixedly connected with the grabbing arm; and a baffle plate is formed on a rack. According to the grabbing Chinese yam seeder, through cooperation of the crank-link mechanism and the mechanical arm, the mechanical arm grabs Chinese yam circularly to seed and grabs one Chinese yam seed each time, the grabbing accuracy is high, the problems of seed blockage and leakage are solved. In addition, by using a tractor for traction, ditching, seed discharging, seeding, earthing and tapping are completed at one time, so that the number of grinding times for soil is reduced, the work efficiency of a machine is improved, conversion from manual seeding to automatic seeding is achieved and the labor burden is reduced.

Description

technical field [0001] The invention relates to a grab type yam seeder. Background technique [0002] Since 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 yam planting area and consumption. 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 been basically 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. Therefore, the overall degree of mechanization of yam is still very low. Yam is a produ...

AI Technical Summary

Problems solved by technology

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 artificial discharge and sowing. This traditional planting method is very inefficient and time-consuming.

Although there is a yam seeder, the machine has the problem of seeding, and it cannot be fully automated, nor can it completely liberate the labor force

These backward sowing methods have greatly restricted the large-scale production and development of Chinese yam
