[0002] The seed tray is the core component of the air-suction seed meter. When the seed tray rotates, the seeds are adsorbed on the seed tray under the negative pressure of the vacuum chamber and rotate with the seed tray. When the seeds are rotated out of the vacuum chamber, they are no longer under negative pressure, and the seeds fall into the soil by their own weight or under the action of the seed scraper, completing the sowing process. When installing each seed meter of the same seeder, the seed suction holes of the seed tray of each seed meter must be kept in the same position. However, it is difficult to keep the seed tray in the same state by manual visual observation alone. Different positions of the seed tray will result in different seed placement positions for each row of seeds, affecting the sowing effect. Summary of the invention

[0035] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0036] Figure 1 This is the exploded view of the seed plate zero position adjustment device;

[0037] Figure 2 This is the axonometric view of the seed tray zero position adjustment device of the seeding device;

[0038] The invention discloses a disk zero position adjustment device, comprising:

[0039] A seed meter housing 12, a motor support 15 is installed on one side of the seed meter housing 12;

[0040] The seeding device shaft 8 is rotatably connected to the seeding device housing 12, and the seeding disk hub 4, the seeding disk 3, and the stirring disk 2 are sequentially installed on the seeding device shaft 8;

[0041] The motor support 15 is provided with a detection collar 16 which is installed on the seed metering device shaft 8 and has a detection point. The detection collar 16 has a first working position and a second working position.

[0042] The motor support 15 is provided with a detection hole;

[0043] The zero position adjustment card plate 1 is arranged at the end of the seed metering device shaft 8 and is fixed in position;

[0044] The zero-position adjustment card plate 1 is provided with a position-limiting member for fixing the position of the seeding disc 3;

[0045] When the detection collar 16 rotates relative to the seeding device shaft 8 and is in the second working position, the zero position detection sensor 7 installed on the motor support 15 can detect the detection point, and the zero position detection sensor 7 sends a signal to the indicator light, the indicator light is on, and the zero position adjustment of the seeding disc 3 is completed (as shown in Figures 5 and 6).

[0046] Preferably, when the detection collar 16 is in the first working position, the detection collar 16 is fixedly connected to the seed metering device shaft 8, and when the detection collar 16 is in the second working position, the detection collar 16 can rotate relative to the seed metering device shaft 8;

[0047] Specifically, a set screw 17 is installed on the detection collar 16, which abuts against the seed meter shaft 8 through the set screw 17 to fix the detection collar 16 on the seed meter shaft 8. By loosening the set screw 17, the detection collar 16 can be driven to rotate relative to the seed meter shaft 8, so that the zero-position detection sensor 7 detects the detection point on the detection collar 16 through the detection hole on the motor support 15. At this time, tighten the set screw 17 to switch the detection collar 16 from the second working position to the first working position, thereby completing the zero-position adjustment of the seed disk 3.

[0049] Both ends of the zero position adjustment card plate 1 are provided with mounting holes for connecting between the seed meter housing 12 and the seed meter shaft 8, and the zero position adjustment card plate 1 is provided with a plurality of limit holes corresponding to the seed suction hole positions of the seed disk 3, and the limit member can be connected to any seed suction hole of the seed disk 3 through the limit member.

In this embodiment, a bolt is taken as an example, and a bolt is passed through one of the limiting holes in a row on the zero position adjustment card plate 1, and at the same time, it passes through any seed suction hole on the seeding disk 3 to fix the seeding disk 3. Among them, the zero position adjustment method of other seeding devices on the same seeder is the same as that of adjusting the zero position of the seeding disk 3 of the first seeding device. The upper limit hole of the zero position adjustment card plate 1 adopts the limiting hole in the same position, and the zero position adjustment card plate 1 is removed when the zero position adjustment of the seeding disk 3 is completed.

This embodiment only takes a bolt as an example, and other rod-shaped members can also be used.

[0059] The present invention also discloses an air-suction electric-driven seed-drilling device, which includes the above-mentioned seed tray zero-position adjustment device, and a plurality of seed-drilling devices are provided on the same seed drill;

[0060] In the seed disc zero position adjustment device of the seed meter, a sealing ring 11, a sealing ring pressing piece 9, a seed disc hub 4, a seed disc 3, and a stirring seed disc 2 are sequentially mounted on the seed meter shaft 8.

[0061] In the above technical solution, the present invention provides an air-suction electric-driven seed metering device;

[0062] Working principle:

[0063] The air-suction electric-driven seeding device generates negative pressure through the fan, and the negative pressure is transmitted to the vacuum chamber of the seeding unit. When the seeding disc 3 rotates, the seeds are adsorbed on the seeding disc 3 under the action of the negative pressure in the vacuum chamber, and rotate with the seeding disc 3. When the seeds are rotated out of the vacuum chamber, they are no longer subjected to negative pressure, and the seeds fall into the soil by their own weight or under the action of the seed scraper, completing the sowing process;

[0066] The zero position adjustment card plate 1 is installed on the seeding device shaft 8 and the connecting bolt 10 through the mounting holes at both ends. A limit piece is passed through any limit hole in a row of limit holes on the zero position adjustment card plate 1, and at the same time, it passes through any seed suction hole on the seeding disk 3. The seeding disk 3 is fixed, the set screw on the detection collar 16 is loosened, and the detection collar 16 is rotated until the detection bolt is detected by the zero position detection sensor 7, the indicator light is on, and the set screw is fixed. The zero position adjustment method of other seeding devices on the same seeding machine is the same as that of adjusting the zero position of the seeding disk 3 of the first seeding device. The upper limit hole of the zero position adjustment card plate 1 adopts the limit hole in the same position. When the zero position adjustment of the seeding disk 3 is completed, the zero position adjustment card plate 1 is removed. The device effectively solves the problem that it is difficult to keep the seeding disk in the same state by relying on manual naked eye observation, resulting in different seed placement positions for each row of seeds, which affects the sowing effect.
