Supply brushes for agricultural machinery, brush rollers for planting machinery, brushes for planting machinery1

The utility model relates to a seeder used for a hand-operated seedling raising seeder. The lower part of the cross section of its seed box is 'V'-shaped, and the bottom intersection is the seeding opening. Below the seeding opening, there is a cylindrical large seeding wheel along the vertical center line of the cross section of the seed box. The cylindrical large seeding The surface of the outer edge of the wheel is evenly provided with seeding grooves running through the two ends parallel to each other. Between the outer edge of the rear side of the large cylindrical seeding wheel and the edge of the inclined bottom plate on the other side of the center line, there is a seed collecting plate, and the large cylindrical seeding wheel The front side is equipped with a seed guard, and the upper part of the cylindrical large seeding wheel is equipped with a cylindrical brush, and the outer edge of the cylindrical large seeding wheel and the cylindrical brush are tangent. The utility model has the advantages that: due to the adoption of the columnar seeding wheel for seeding, the linear speed of the outer edge of the seeding wheel is relatively low, which greatly reduces the rate of damage to the buds; the rotation speed of the columnar seeding wheel is mainly adjusted by replacing the sprocket. The brush micro-adjustment is supplemented, and the speed ratio of the columnar seeding wheel and the seedling tray conveying mechanism is realized by changing the sprocket, and the sowing amount can be adjusted in a large range.
