Description

Technical Field

[0001] The utility model relates to the field of seed drill equipment, in particular to a seed box for a seed drill. Background Art

[0002] At present, when the seeder is sowing, there are two ways to install the seeding device, one is side by side installation, and the other is one front and one back installation. When the side-by-side installation method is adopted, the disc opener at the bottom of the seeding device will produce soil furrows when digging the soil. Since the two disc openers are very close, the soil will gather in the middle, causing congestion in the middle, forming a pile of soil, and accumulating in front of the opening disc, affecting the advancement of the opening disc, making the ground uneven, and the seed depth does not meet the sowing requirements. When the one-front-one-back installation method is adopted, the seeding device will not be congested during sowing, but the discharge ports at the bottom of the existing seeding box are mostly arranged side by side, and the inclination angles when the discharge pipe is connected to the seeding device are inconsistent, resulting in a large difference in flow rate when the seeds are discharged, uneven seeding of the seeding device, and affecting the sowing effect. Utility Model Content

[0005] The seed discharging openings at the front and the seed discharging openings at the rear are arranged alternately.

[0006] The seed discharge port is a circular seed discharge port.

[0007] The seed discharging port is a long waist hole, and a group of regulating pipe openings used in conjunction with the seed discharging port are arranged on the bottom surface of the box body.

[0008] The adjusting pipe mouth is composed of an adjusting plate and a discharge pipe. The adjusting plate is provided with at least one pair of long waist holes. Bolts pass through the long waist holes. Nuts are screwed on the bolts to fix the adjusting plate on the seed discharge port. The discharge pipe is fixedly installed in the middle of the adjusting plate.

[0009] The outlet end of the discharge pipe is provided with a flange, and the discharge pipe is connected with the feed port of the seed metering device through an arrangement hose.

[0010] Box fixing plates are respectively arranged on both sides of the box.

[0011] The utility model has the advantages that the sowing box adopts a W-shaped box bottom, so that the discharging pipe and the seed metering device are connected at the same inclination angle, the seed discharging flow rate is consistent, and the sowing is smooth.
