[0023] With reference to Figure 1-5 , the utility model discloses a no-tillage air suction type precision seeder, it includes: car body 1, the left surface fixed connection of car body 1 has vertical board 2, the left surface fixed connection of vertical board 2 has mounting frame 3, flat plate 4, the left end fixed connection of mounting frame 3 upper surface has mounting block 7, the upper surface of car body 1, flat plate 4, mounting rod 9, mounting block 7 between fixed connection has seeding and fertilizing mechanism 5, the left surface fixed connection of mounting frame 3 has no. 1 mounting frame 11, the lower end fixed connection of no. 1 mounting frame 11 has soil breaking cutter 12, the surface fixed connection of soil breaking cutter 12 has material guide shell 13, and material guide shell 13 lower surface is provided with material falling hole 21, the left surface fixed connection of mounting frame 3 has two pedals 8, and pedal 8 is located at the front and rear ends of mounting frame 3, and seeding and fertilizing mechanism 5 and material guide shell 13 are mutually penetrated through conduit, and the above components cooperate, form the basic structure of seeder, wherein seeding and fertilizing mechanism 5 is composed of seed storage box, fertilizer storage box, seed divider, fan, conduit, and is the air suction type seeding structure commonly used for seeder.

[0024] Specifically, during the forward movement of the vehicle body 1, the soil-breaking blade 12 penetrates the ground to break the soil and form a trench. Meanwhile, the seed separator uses the suction provided by the blower to remove the seeds from the seed storage box. The seeds enter the conduit connected to the guide shell 13 through the conduit and fall into the trench through the drop hole 21 at the bottom of the guide shell 13.

[0025] Multiple mounting brackets 19 are fixedly connected to the lower end of the vertical plate 2. Wolf-tooth rollers 14 are rotatably connected to the left and right sides of the end of the mounting bracket 19 furthest from the vertical plate 2. The two wolf-tooth rollers 14 on the left side of the mounting bracket 19 have a V-shaped inclined structure and are located between the two side plates 18 in the limiting assembly 10. A T-shaped plate 17 is located between the two wolf-tooth rollers 14. The wolf-tooth rollers 14 are used to turn over the broken soil on both sides of the trench, restoring the turned-over soil to cover the seeds and fertilizer. A long... The lower surface of the long plate 15 is fixedly connected to a protective component 6. The protective component 6 consists of two side plates 18, a T-shaped plate 17, and a spring rod 16. The side plates 18 are fixedly connected to the lower surface of the long plate 15, and the T-shaped plate 17 is fixedly connected to the long plate 15 through the spring rod 16. The lower end of the T-shaped plate 17 and the surface of the side plates 18 do not contact the surface of the toothed roller 14, and the upper end of the T-shaped plate 17 does not contact the second mounting bracket 19. The protective component 6 is used to scrape off the dirt attached to the surface of the toothed roller 14 in a timely manner.

[0026] Specifically, as the vehicle body 1 continues to move forward, the spiked roller 14 rotates after contacting the soil turned over by the soil being broken up. Utilizing the V-shaped structure of the two spiked rollers 14 facing each other, the soil turned over on both sides of the trough is pushed into the trough to cover the seeds and fertilizer. During the rotation of the spiked roller 14, the soil attached to its surface directly collides with the side plate 18 and the T-shaped plate 17, thereby scraping off the soil attached to the surface of the spiked roller 14.

[0027] Both the left and right surfaces of the mounting frame 3 have limiting components 10. The lower end of the limiting component 10 penetrates the long plate 15. The limiting component 10 consists of a mounting box 22, a mounting plate 23, teeth 24, and a support spring 20. The mounting box 22 is fixedly connected to the mounting frame 3. The support spring 20 is fixedly connected to the inner wall of the mounting box 22. The mounting plate 23 is fixedly connected to the end of the support spring 20 away from the inner wall of the mounting box 22. The teeth 24 are fixedly connected to the side of the mounting plate 23 away from the support spring 20. The surface of the mounting plate 23 is in contact with the inner wall of the mounting box 22. The teeth 24 have an upwardly inclined structure. An inclined slot is provided at the point where the long plate 15 is penetrated by the limiting component 10. In the inclined state, the teeth 24 and the inclined slot form a self-locking structure. The limiting component 10 is used to limit the range of motion of the long plate 15 and improve the stability of the protective component 6 when it is in action.

[0028] Specific, between the seeding work, manually press the mounting plate 23, make the mounting plate 23 surface tooth 24 away from the inclined slot, the long plate 15 lack of tooth 24 limit naturally fall, thus change the height of the protection assembly 6, after finding the height of the lower end of T-shaped plate 17 is lower than the height of the lower end of the second mounting frame 19, remove the limit for mounting plate 23, the mounting plate 23 is affected by the support spring 20 pop out mounting box 22, so that the tooth 24 again enter the inside of the inclined slot for long plate 15 provide support force, and in the process of seeding machine before the installation plate 23 will not be affected by the external force to the inside of the mounting box 22, therefore will not appear the mounting plate 23 automatically enter the mounting box 22.

[0029] Working principle: first change the height of the long plate 15, reduce the height of the long plate 15, make the lower end of the T-shaped plate 17 height is lower than the second mounting frame 19, ensure that the mud attached to the surface of the wolf tooth roller 14 and the lower end of the T-shaped plate 17 contact, T-shaped plate 17 is scraped off, so as to avoid the wet soil stuck in the wolf tooth roller 14 and the second mounting frame 19, reduce the height of the long plate 15, manually press the mounting plate 23, make the support spring 20 compression, at this time the mounting plate 23 into the inside of the mounting box 22, and the tooth 24 away from the long plate 15 card joint, the long plate 15 lack of tooth 24 limit naturally fall, thus reduce the height of the protection assembly 6, wolf tooth roller 14 compaction, suspended broken soil cutter 12 as furrow opener, ensure the uniformity of seeding depth, after the wolf tooth roller 14 independent compaction, compaction, conservation, ensure the uniformity of emergence, each seed has sufficient nutrients.

[0030] The above embodiment of the present application is described in detail in combination with the drawings, but the present application is not limited to the above embodiment, within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the purpose of the present application.
