Description

Technical Field

[0001] This utility model belongs to the field of seeding machinery technology, and specifically refers to an offset duckbill structure for a seeder. Background Technology

[0002] Currently, the seeders used in existing seeders generally consist of a fixed and a movable spout. The movable spout is hinged to the fixed spout. Upon contact with the ground, the fixed and movable spouts press into the soil to form a seed hole. Simultaneously, by pressing the ground, the movable spout is activated, and the seeds accumulated in the fixed and movable spouts fall into the seed hole along the fixed spout, thus completing the sowing operation. However, when using existing seeders, because planting requires drip irrigation tape to be laid under the film and sowing is done after mulching, the spacing between the two parallel seeding trays is too small, and the drip irrigation tape is located between the two trays. This often results in damage to the drip irrigation tape due to the spout crushing it. Furthermore, due to the operation of the seeder, the falling seeds often scatter and land at the edge of the seed hole, resulting in low seed concentration and uneven emergence. For mulched sowing, this often leads to the emergence position deviating from the film holes, causing emergence difficulties and affecting the crop emergence rate. Utility Model Content

[0003] The purpose of this invention is to provide a reasonably structured, offset duckbill structure for the seeders, which increases the spacing between the seeders and reduces the risk of damage to the drip irrigation tape.

[0004] The purpose of this utility model is achieved as follows:

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0022] like Figures 1-3As shown: An offset duckbill structure for a seeder includes an offset guide plate 1, a duckbill connecting plate 2, a duckbill sleeve 3, a movable plate 4, and a reset component 5. The duckbill connecting plate 2 is provided with an offset hole 21. The upper opening of the duckbill sleeve 3 is located below the offset hole 21. The movable plate 4 is rotatably disposed on one side of the lower opening of the duckbill sleeve 3, and the movable plate 4 is always closed by means of the reset function of the reset component 5. The offset guide plate 1 is located above the duckbill connecting plate 2, and a material guiding channel 11 is provided inside the offset guide plate 1. The offset hole 21 is located on one side of the lower opening of the material guiding channel 11. The offset duckbill structure can increase the spacing between seeders, reduce damage to drip irrigation tape, and extend the sowing spacing.

[0023] In the above-mentioned offset duckbill structure of the seeder, the lower end of the duckbill sleeve 3 is provided with an inclined surface 31, and the movable plate 4 cooperates with the inclined surface 31. Specifically, the two cooperate to facilitate the insertion of the duckbill into the soil.

[0024] In the aforementioned offset duckbill structure of the seed planter, the movable plate 4 includes an integrally formed closing part 41 and an opening part 42. The closing part 41 at least partially cooperates with the inclined surface 31. The opening part 42 is subjected to pressure to cause the closing part 41 to open the lower opening of the duckbill sleeve. The movable plate 4 has an L-shaped structure. Specifically, when the duckbill is inserted into the soil, the seed planter rotates. When the opening part contacts the ground, the lever principle controls the closing part to open. After the seed enters the soil, the opening part leaves the ground. Finally, the reset member pushes the opening part to reset, and the closing part closes the lower opening of the duckbill sleeve.

[0025] In the above-mentioned biased duckbill structure of the seeding device, the reset element 5 is a reset spring, and its two ends are respectively connected to the movable plate 4 and the duckbill connecting plate 2.
