SEED SOWING DEVICE

Application for direct sow seeds

This seed sowing device is suitable for sowing small seed of crops that require thin the clusters crops such as spinach, radish, carrot, Chinese cabbage, cabbage, and the sunflower for ornamental cut flowers, etc. It dispenses seeds via a seeding disc.

In addition to seeding discs with regular dispensing holes, there is a spare seeding disc without dispensing hole for self-processing to suit other seed size and spacing.

Due to the straight line sowing, the row spacing is regular, which is conducive to field management operations such as fertilization and weeding.

Characteristic

1. There is a 25mm x 25mm square link buckle in front of the device for easily locking at a square connecting steel rod pipe, which link at the tractors, cultivators or manual propulsion equipment for manual seeding.
2. Easy to add or reduce seeding rows. Quickly assemble and disassemble.
3. Lightweight for easy working, improve work efficiency.
4. Eliminate the parts of not necessary, concise structure of device make cost reasonable. This is an easy vegetable seeder
5. Save seeding work and reduce seed costs. Reduce the thinning operation of clusters crop.
6. It is very easy to operate with this device and can be operated without special training.

Structure of seed sowing device

The seed sowing device is mainly constructed with a square link buckle portion, a seeding and land wheel portion, and a seed drop portion.

1. The square link buckle is in front of the seed sowing device. It is used to be locked to a 25mm x 25mm square connecting steel rod pipe. The square connecting steel rod pipe can be connected and fixed to the pulling equipment, such as tractors, cultivators or even manpower device.

2. The seeding and land wheel portion includes a seed box, a seeding case, a seeding disc, a barrier brush and a land wheel.
3. The seed box is placed above the seed sowing device to load the seeds. It includes two parts: the seed box body and the lid.
4. The seeding case is under the seed box, includes the seeding case body and the cover. To be used to place a seeding disc.
5. The seeding disc is located in the center of the seeding case. At its outer edge has some concave seed dispensing holes. There are three seeding discs with regular holes for radish, leeks and spinach.

In addition, there is a spare seeding disc without seed dispensing hole. This spare seeding disc is for self-processing concave holes to meet the needs of various vegetable seeds.

Seeding disc is changeable for different sizes of seeds with different drop distance.

1. The barrier brush is located at the upper going edge of the seeding case to remove excess seeds.
2. The center of the seeding case has a drive shaft that runs vertically through the seeding case. A section of drive shaft out of seeding case is used to install a plastic land wheel.
3. The seed drop portion contains a ditching duct and a soil covering plate. The ditching duct can be adjusted according to the ditch depth for seeding. The soil covering plate is used to cover the soil on the seeds that fall on the ground.
4. 

How the seed sowing device working

The seed sowing device pulled by power, then the land wheel turn forward. Seeds are down from the seed box to the seeding disc with certain volume in certain distance, finally the seeds down into the soil via the ditch duct below. The delivery of the seeds utilizes its own weight.

When falling into the seed dispensing holes of the seeding disc, the seeding disc is turned forward in a counterclockwise direction. The inside of the seeding case has a concave guide groove above the outer edge. The seeds to be broadcast will enter here. Before entering, due to the blocking of barrier brush, the extra seeds in the seeding disc hole will be swept out. The seed dispensing holes set the distance and volume to drop the seeds.

The rotation of the seeding disc is driven by the coaxial land wheel. When in contact with the soil, land wheel drives the drive shaft and rotates the seed disc.

The seeds are introduced into the ditching duct and then fall into the ditch, which is then covered with soil by soil covering plate. In this way, ditching, sowing, and covering soil have been completed the same time.

The circumference of land wheel is around 100 cm so the dispensing distance of seeding disc is around 100 cm a turning circle. The dispensing distance of each hole is divided by the quantity of hole.

Seed sowing device operation steps:

1. The soil in the sowing bed should be loosed first.

When deciding the type of vegetable, select the seeding disc depend on the volume and distance of dispensing holes.

After selecting the appropriate seeding disc, open the cover of seeding case and place the seeding disc in the seeding case. Then adjust the gap between brush and seeding disc, and adjust the sowing depth of ditching duct.

2. Place the seeds in the seed box.
3. For seeding seeds, if we need to cover the soil, the ditching duct and soil covering plate below the seeding case must be installed. We can adjust the ditching duct and soil covering plate as the depth needed.

If the seeds do not need to be covered, the ditching duct and soil covering plate can be removed.

4. Before starting the seeding operation, rotate the land wheel goes forward for a half turn first. After confirm the seed is dropped to the ditching duct, the seeding operation can be started.

In this way, the initial 30 cm sowing missing can be avoided.

5. During operation, pay attention to whether the land wheel rotates normally. That can avoid the intermittent seeding.
