Technical Field

[0001] The utility model relates to the technical field of agricultural planting, in particular to a seeder with adjustable sowing range. Background Art

[0002] With the rapid development of modern agriculture, sowing is a key link in agricultural production. The use of seed drills has become quite common. By replacing manual sowing, it reduces labor and increases sowing efficiency.

[0003] Existing seed drills are generally divided into two types. One is a large device that performs seeding work by being installed on agricultural equipment such as tractors. It has the advantages of high efficiency and the ability to seed multiple planting paths, but it is expensive and is mostly used in large farmlands. The other is a small seed drill that is mostly pushed manually and continuously picks up and unloads materials for seeding through the bottom disc as it rotates. Although the cost is low, it is difficult to adjust the seeding spacing range with this device. The adjustment effect can only be achieved by changing different sizes, which makes it less practical.

[0031] Reference Figure 3-4In order to adjust the sowing interval range, an adjustment component is set on the outer wall of the rotating rod 8. The adjustment component includes the second gear set 11 and the first gear set 10. The outer wall of the rotating rod 8 is slidably sleeved with an outer cylinder 24. The second gear set 11 is sleeved on the outer wall of the outer cylinder 24 and includes the second large gear 14, the second medium gear 15 and the third small gear 16 in sequence, and the sizes are successively reduced. The first gear set 10 is sleeved on the outer wall of the rotating shaft 7 and includes the first small gear 19, the first medium gear 18 and the first large gear 17 in sequence, and the sizes are successively increased. The second large gear 14 cooperates with the first small gear 19, the second medium gear 15 cooperates with the first medium gear 18, and the first large gear 17 cooperates with the third small gear 16;

[0032] Specifically, the sliding outer cylinder 24 meshes the gears of other sizes with the gears on the outer wall of the rotating shaft 7, and controls the rotation speed of the sowing cylinder 6 through the transmission difference between the large and small gears, thereby adjusting the spacing between sowings.
