Multi-row precision seeder

Abstract

A multi-row precision seeder comprises a frame with road wheels, ditching devices, fertilizer applicators and a seed metering devices, every seed metering device comprises a material storage box, wherein concave chambers are respectively arranged at two sides of the material storage box, the material storage box are provided with a seed filling plate and a rotating disc corresponding to the concave chambers, the seed filling plate and the concave chambers form a material storage chamber, the bottom of the material storage chamber is a seed filling area, the seed filling plate is provided with a plurality of seed accommodating pits, every seed accommodating pit is provided with a seed eduction opening, the rotating disc is provided with seed accommodating chambers corresponding to the seed accommodating pits, a separator plate is arranged between the seed filling plate and the rotating disc, and the separator plate is provided with seed delivery holes; and the material storage box is provided with a baffle sleeve which sleeves the rotating disc, the bottom end of the baffle sleeve is provided with a seed discharging opening, every seed accommodating chamber is provided with a seed outlet which communicates with the seed discharging opening when seeds move to the position of the seed discharging opening, and the multi-row precision seeder also comprises a rotating driving device for driving all the seed filling plates and the rotating disc to simultaneously rotate. The multi-row precision seeder has the advantages of simple and compact structure, low cost, convenience in installation and maintenance, high working efficiency, good reliability and stability, low seed breaking rate and low missing seeding rate.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a multi-row precision seeder. Background technique [0002] At present, there are the following types of cotton precision seeders with better performance: [0003] 1. Air-suction cotton precision seeder. Its stable working speed is about 3.5KM / H. When the seed meter is working, a vacuum is generated in the seed meter cavity, and the seeds are adsorbed on the suction hole under the action of the pressure difference, and the seeds move at a uniform speed synchronously with the radial groove plate. During the movement, the excess seeds are removed by gravity, and only one seed is left, which is thrown into the inner cavity of the duckbill along the radial groove plate by its own weight, and reaches the top of the duckbill with the roller to complete one seeding. When the duckbill rotates to 15° vertical to the ground and penetrates the plastic film into the soil, th...

AI Technical Summary

Problems solved by technology

However, it has poor adaptability to cotton seeds, strict requirements on seed size, low operation quality, and it is difficult to meet the requirements of precision sowing and high-speed operation.

It has the functions of picking, clearing and sorting seeds, but it does not have the function of protecting seeds. It cannot adapt to the inclination of the seed meter caused by uneven ground, nor can it adapt to the situation where the seeder vibrates greatly; °It is in full-line working condition, and the mechanism is seriously worn

[0010] 3. The electromagnetic cotton precision seeder is to make a fuss about the coating of cotton seeds, that is, add a certain amount of magnetic powder to the coating powder, and use the generation and disappearance of magnetic force to implement the seed collection and discharge of the seed meter. The planter produces irregular mechanical vibrations when it is working, and it is in a muddy environment that is unfavorable to the electric control components, resulting in poor contact of the circuit or failure of the electric control components, making the seed meter poor in stability or unable to work, so it has not been used so far. widely used
