Chinese yam seeder

Abstract

The invention discloses a Chinese yam seeder which comprises a rack and traveling wheels, and further comprises a seed conveying mechanism and a seed-metering mechanism, wherein the seed conveying mechanism is used for conveying Chinese yam seeds into a seeding trough; the seed-metering mechanism is used for conveying the Chinese yam seeds to the seed conveying mechanism; the seed conveying mechanism comprises a chain slot formed longitudinally; the chain slot comprises baffles on both sides; a seed outlet of the seed-metering mechanism is communicated with the chain slot; a seed conveying closed structure is formed in the bottom of the chain slot and comprises a sector gear and an incomplete gear meshed with each other, and the sector gear and the incomplete gear are driven by the traveling wheels; the sector gear is arranged below the baffle on one side of the chain slot and connected with a closed baffle; in the rotating process of the sector gear and the incomplete gear, the closedbaffle can be closed with or separated from a chain slot baffle on one side disconnected with the sector gear. Aiming at morphologic characteristics of the Chinese yam seeds, in order to prevent orientation changes of the Chinese yam seeds in the dropping process, a Chinese yam seed direction correction closing mechanism is designed at the lower seed outlet, so that the seeds can be smoothly seeded into the seeding trough according to a certain orientation, and the agricultural requirements are met.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a yam seeder. Background technique [0002] At present, the research and development level of domestic yam seeding machinery is relatively low, and the research and development process is relatively slow. At the same time, with the increase of demand, the total domestic yam production and planting area have increased greatly in recent years. The annual output is about 5 million tons, and the planting area is about 250,000 hectares. Compared with other countries in the world, my country has the largest total area of ​​yam planting area, and my country is also the country with the largest consumption of yam. As the market of yam continues to expand, its mechanized demand for sowing will also continue to expand, which can better ensure the improvement of economic benefits. [0003] The current yam seeder is generally connected to the tractor through a three-point su...

AI Technical Summary

Problems solved by technology

Most of the domestically developed yam seeders are single-operation machines, such as machines for covering soil and compacting alone. Although this type of machine can liberate part of the labor force, it has only initially completed a certain part of the mechanization of yam seeding, and has not integrated a series of steps for yam seeding. to the all-in-one machine, and the operation is relatively complicated, the work efficiency is low, the adaptability is poor, and the loss rate is too large

[0004] The yam seeder in the prior art mainly has the following problems: (1) the existing yam seeder has many components of manual intervention, the labor intensity is too high, and the degree of automation is low. Realize automatic execution of the machine, but functions such as missing seeds and replanting need manual detection and manual replanting, which affects the efficiency of yam sowing; (2) yam seeds have larger volume and longer length than granular seeds such as corn and wheat. characteristics, and the yam seeds are required to be sown head to tail, and there are directional requirements. If the direction of the yam seeds is not adjusted, the subsequent growth of the yam will be affected; Problems such as good seeding and stuck seeds will cause seed damage, affect the sowing efficiency and have a negative impact on the growth of yam in the later stage
