Seed cylinder assembly structure for miniature potato seeder

Abstract

The invention provides a seed cylinder assembly structure for a miniature potato seeder. The seed cylinder assembly structure comprises a support frame, a seed cylinder, an auxiliary seed box and a seeding furrow opener, wherein the support frame is fixedly connected with a body of the seeder; the seed cylinder is fixed on the support frame by a special U-shaped structure; a vibration motor mounting hole is formed in the seed cylinder; seeding sprocket shaft supporting holes are formed in the upper and lower positions; the auxiliary seed box is fixed at the lower middle part of the support frame, a seeding chain port is formed in the bottom, miniature potatoes are extracted from the auxiliary seed box by seed spoons on seeding chains, the seed spoons are uniformly distributed and fixed onthe seeding chains, and the seeding chains bypass a drive sprocket at the upper part and pass through a driven sprocket at the lower part to be connected; a vibration motor is mounted at the middle-upper part of the support frame, a roller at the shaft end of the vibration motor rotates to drive the seeding chains to vibrate and clear out the redundant potatoes in the seed spoons, and repeated seeding is avoided; the seeding furrow opener is fixed at the lowermost part of the support frame and performs furrowing for seeding, and spray nozzles are mounted at the lower part of the support frame,located between two rows of seed chain protecting cases and arranged on the front and back respectively and have the main function of weeding.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a seed tube assembly structure of a miniature potato planter. Background technique [0002] At this stage, my country, as a major potato-producing country, ranks among the top in the world in planting area and output, and is the fourth largest food crop in the world. It plays an important role in ensuring domestic food security, energy security and poverty eradication. However, compared with developed countries, there is still a big gap between the level of potato mechanized production in my country and the development of potato mechanized production technology in China. Therefore, under the trend of accelerating the transformation of extensive production methods and vigorously developing the mechanization of potato production, improving the mechanization level of potato sowing is of great significance for reducing the labor intensity of farmers and increasing farm...

AI Technical Summary

Problems solved by technology

[0003] At present, most of the domestic potato planters sow diced seed potatoes. The diced seed potatoes have the disadvantage of low survival rate, and the diced seed potatoes are of different sizes, resulting in serious waste.

It cannot meet the growing demand of potatoes in our country, which requires the development of a miniature potato planter seed tube assembly mechanism
