A precision seeding machine for plug seedlings

Abstract

The invention discloses a plug seedling precision seeder, which comprises a vibrating platform module. The vibrating platform module comprises a piezoelectric element and a narrow seed tray of which the size satisfies the seed suction requirement of the first and second rows of holes on a seed sucking tray; the piezoelectric element is installed on the narrow seed tray and externally connected with a drive power source. The plug seedling precision seeder disclosed by the invention has the advantages of: reducing the size of the seed tray, saving the cost, solving the problem that the seeds cannot be sucked because of deflective concentration of the seeds, greatly reducing the power consumption and various noises such as electromagnetic noise, pneumatic noise and mechanical noise, easily achieving reliability control and regulation, greatly increasing the service life and safety, and ensuring that the position of a dribbling head of a dribbling mechanism and the positions of the seed sucking holes are respectively corresponding to the positions of the seed discharging holes on the plug via concentrated driving so as to finish the precise seeding process of the seeder. The plug seedling precision seeder is benefit for application and popularization, saves a great amount of labor and materials, improves the work environment and labor intensity of technicians for planting, and achieves good economic and social efficiencies.

Description

[0001] technical field [0002] The project described in the present invention belongs to the field of precision seeding technology for industrialized plug seedling cultivation in facility cultivation, and specifically relates to a precise variable seeding machine for plug seedling cultivation that can meet the precise variable seeding requirements of 1-multiple grains / hole. Background technique [0003] The precision seeding equipment for plug seedling raising is a key equipment in industrial seedling raising technology. One of the most important devices is the precision seeding device. It is mainly used for precision seeding and sowing of seedlings such as vegetables, flowers, forest trees and rice. It has the advantages of saving the amount of high-quality seeds, high and neat emergence rate, increasing production and income, etc. [0004] The seeds in the seed tray of the precision sowing device are loose materials. The theory of granular dynamics shows that in ord...

AI Technical Summary

Problems solved by technology

[0006] 1) The service life and maintenance requirements are high, the parts and components have many and complex structures, and the precision requirements in manufacturing, installation, and use are high. For example, the seed tray must be kept at a constant level during vibration, otherwise the seeds will be seriously segregated and cause seed suction. cannot proceed;

[0007] 2) High power consumption and high working noise, such as electromagnetic noise, pneumatic noise, mechanical noise;

[0008] 3) The unevenness of the vibration caused by the manufacturing error of the vibrating table surface, the uneven mass distribution, and the uneven return spring parameters of the seeds on the seed plate are prone to seed segregation, resulting in the failure of seed suction;

[0011] 6) The existing vibration method sometimes requires special treatment when sowing small seeds, which increases the cost of sowing
