[0035] As a technical optimization solution of the present invention, a supporting frame 8 is matched and fixed below the rectangular frame 1, and both ends of the supporting frame 8 can be connected to an existing mobile device, such as a powered electric wheel, or the supporting frame 8 as a whole can also be installed on the upper side of the conveyor belt.

The rectangular annular block 9 plays a role in limiting the rectangular vibration disk 3, and at the same time can ensure that the upper end of the rectangular vibration disk 3 covers the rectangular shell 2, thereby limiting the vibration amplitude of the rectangular vibration disk 3.

[0037] As a technical optimization solution of the present invention, the port of the rectangular vibration disk 3 has the same shape as the air suction cup 4, and the area of ​​the rectangular vibration disk 3 is larger than the area of ​​the air suction cup 4.

The rotating shaft of the rubber roller 19 is arranged vertically, and the side of the rubber roller 19 contacts and matches with the bending block 20. As the rectangular shell 2 moves, the bending blocks 20 at both ends of the scraper 13 touch the rubber roller 19 respectively, so that the corresponding slider 14 slides on the slide rail 15, and the scraper 13 translates inside the rectangular vibration disk 3, and the scraper 13 performs a leveling operation on the rice seeds inside the rectangular vibration disk 3.

[0040] As a technical optimization scheme of the present invention, the sealing mechanism includes a sealing plate 21 horizontally arranged at the end of the discharge port 7, rectangular notches 22 are provided at both ends of the sealing plate 21, and both ends of the sealing plate 21 slide through the discharge port 7, an intermediate block 23 is fixed on the upper side of the middle part of the sealing plate 21, the intermediate block 23 extends to the upper side of the discharge port 7, and the discharge port 7 is provided with a slide groove matching the intermediate block 23, and light rods 24 are fixed on both sides of the intermediate block 23, and two fixed blocks 25 are symmetrically fixed on the upper side of the discharge port 7, the two light rods 24 slide through the two fixed blocks 25 respectively, and the two light rods 24 are coaxially sleeved with reset springs 26 on the outside, the reset spring 26 is located between the intermediate block 23 and the fixed block 25, and the reset spring 26 plays a reset role, and the corresponding two reset springs 26 can reset the intermediate block 23 to the middle position, and the light rod 24 plays the role of stabilizing the reset spring 26. A bending abutment block 27 is fixed in the middle of the blocking plate 21 and extends to the lower side of the discharge port 7. Two bending push blocks 28 are symmetrically fixed to the sides of the rectangular shell 2 corresponding to the bending abutment block 27. The upper ends of the bending push blocks 28 extend to the upper side of the rectangular shell 2 and abut against the bending abutment block 27. The bending push blocks 28 can push the bending abutment block 27, and the bending abutment block 27 pushes the blocking plate 21 to move, so that the rectangular notch 22 at one end of the blocking plate 21 enters the inner position of the discharge port 7. At this time, the discharge port 7 is opened, and the rice seeds in the seed feeding box 6 just slide from the discharge port 7 to the rectangular vibration plate 3.

[0041] As a technical optimization solution of the present invention, a movable plate 10 is provided at the joint between the discharge port 7 and the seeding box 6 for sliding up and down, and an opening aligned with the discharge port 7 is provided in the middle of the movable plate 10. An electric push rod 11 is fixed to the bottom of the seeding box 6, and the telescopic end of the electric push rod 11 is fixedly connected to the bottom of the movable plate 10, and the movable plate 10 corresponds to the sealing plate 21 in parallel.

[0042] As a technical optimization solution of the present invention, the driving mechanism includes two driving motors 29 symmetrically fixed at the bottom of the rectangular shell 2, two racks 30 are laterally symmetrically fixed at the bottom of the rectangular frame 1, and the two driving motors 29 are coaxially fixed with driving gears 31, and the two driving gears 31 are respectively meshed and matched with the two racks 30. A number of position sensors 32 are evenly fixed on the upper side of the rectangular frame 1, and the position sensors 32 are the same as the existing inductive sensors of model LJ12A3. The two driving motors 29 are started, and the two driving gears 31 are respectively meshed and matched with the two racks 30 to accurately control the movement of the rectangular shell 2 and the corresponding rectangular vibration plate 3 on the rectangular frame 1. The position sensor 32 can transmit position information to ensure the accurate movement of the rectangular frame 1.

[0043] As a technical optimization solution of the present invention, the vibration mechanism includes a vibration motor 33 fixed to the bottom of the rectangular vibration plate 3, and a plurality of vibration springs 34 are vertically arranged at the bottom of the rectangular vibration plate 3. The plurality of vibration springs 34 are evenly distributed around the vibration motor 33, and the two ends of the plurality of vibration springs 34 are respectively fixedly connected to the rectangular vibration plate 3 and the rectangular housing 2. The vibration motor 33 is started to vibrate the rectangular vibration plate 3, and the plurality of vibration springs 34 play the role of amplifying the vibration, and at the same time play the role of connecting the rectangular vibration plate 3 and the rectangular housing 2.

[0044] When the present invention is in use, before sowing, a proper amount of rice seeds are placed inside the rectangular vibration disk 3, all the seed adding boxes 6 are pre-filled with rice seeds, and a plurality of air suction cups 4 are raised and reset to the initial position at the top through the electric telescopic rod 5 at the top, and the rectangular shell 2 is located at one end of the rectangular frame 1, that is, the initial position. During the sowing operation, the air suction cup 4 corresponding to the upper side of the rectangular shell 2 is controlled to descend by the electric telescopic rod 5, and the air suction cup 4 extends into the rectangular shell 2, and then the vibration motor 33 at the bottom of the rectangular vibration disk 3 is started, and through the amplification effect of a plurality of vibration springs 34, the rectangular vibration disk 3 vibrates up and down, so that the rice seeds inside the rectangular vibration disk 3 vibrate and jump up, and at this time, the plurality of suction nozzles 12 at the bottom of the air suction cup 4 can more conveniently absorb and absorb the rice seeds. After all the suction nozzles 12 have absorbed the rice seeds, the air suction cup 4 rises, the vibration motor 33 stops, and then the two drive motors 29 are started, and the two drive gears 31 are respectively engaged and matched with the two racks 30 to accurately control the movement of the rectangular shell 2 and the corresponding rectangular vibration disk 3, and accurately move to the bottom of the next air suction cup 4, and then the above-mentioned step of absorbing rice seeds is performed again. When the air suction cup 4 is performing the step of absorbing rice seeds, the previous air suction cup 4 that has completed the absorption is controlled to descend to the bottom of the support frame 8 by the electric telescopic rod 5, and the negative pressure airflow is closed, and the absorbed rice seeds fall, and the rice seeds fall onto the seedling tray prepared in advance on the lower side, completing the precision sowing operation. From the above steps, it can be known that the rectangular shell 2 moves back and forth on the rectangular frame 1 with the rectangular vibration plate 3, and each movement corresponds to the bottom of an air suction cup 4, and then the air suction cup 4 descends to absorb the rice seeds. After the rectangular vibration plate 3 is removed, the air suction cup 4 performs the rice seed sowing operation, and the air suction cup 4 on its side can synchronously perform the seed suction operation while it is performing the sowing operation. The entire continuous process effectively reduces the operating gap between sowing and seed suction, thereby improving work efficiency, which is beneficial to large-scale sowing production.

[0045] At the same time, in the process of the rectangular shell 2 carrying the rectangular vibrating disk 3 to move back and forth on the rectangular frame 1, each time the rectangular shell 2 moves close to one end of the rectangular frame 1, that is, close to the seed adding box 6 on both sides of one end of the rectangular frame 1, the bent push block 28 close to this end on the rectangular shell 2 abuts against the corresponding bent abutment block 27, that is, the two bent abutment blocks 27 at both ends are respectively abutted by the two bent push blocks 28. As the rectangular shell 2 moves, the bent push block 28 pushes the bent abutment block 27, and the bent abutment block 27 pushes the blocking plate 21 to move, so that the rectangular notch 22 at one end of the blocking plate 21 enters the internal position of the discharge port 7. At this time, the discharge port 7 is opened, and the rice seeds in the seed adding box 6 just slide from the discharge port 7 to the rectangular vibrating disk 3, thereby replenishing the rice seeds inside the rectangular vibrating disk 3 and making up for the consumption of rice seeds. At the same time, it is ensured that the rice seeds in the rectangular vibrating disk 3 are maintained at a certain amount, effectively ensuring the seed suction operation of the air suction cup 4, and there is no need to stop the machine for seeding.

[0046] At the same time, after the seed adding operation is performed, the seed suction operation can be performed. After that, when the rectangular shell 2 moves with the rectangular vibration disk 3 to the middle of the rectangular frame 1, the bending push block 28 disengages from the bending abutment block 27. During the disengagement process, the corresponding two reset springs 26 reset the middle block 23, and the light rod 24 plays a role in stabilizing the reset spring 26. The rectangular notch 22 of the blocking plate 21 leaves the internal position of the discharge port 7, and finally the discharge port 7 is closed. And then, as the rectangular shell 2 moves, the bending blocks 20 at both ends of the scraper 13 touch the rubber roller 19 respectively, so that the corresponding slider 14 slides on the slide rail 15, and the scraper 13 translates inside the rectangular vibration disk 3, and the scraper 13 performs a leveling operation on the rice seeds inside the rectangular vibration disk 3, ensuring the vibration and seed suction effect of the rice seeds in the rectangular vibration disk 3, and reducing the impact caused by the uneven terrain of field operations. And with the movement of the rectangular shell 2, the scraper 13 can be completely moved to the other end of the rectangular vibration disk 3, and the slider 14 is magnetically matched with the slide rail 15 to position it, and due to the telescopic effect of the elastic telescopic rod 18, the corresponding bending block 20 can be squeezed into between the two rubber rollers 19 of a T-shaped bracket 16, and the bending block 20 will not affect the movement of the rectangular shell 2 by squeezing and contracting the rubber roller 19 in the subsequent movement. And after reaching the other end, when the rectangular shell 2 moves back, the bending block 20 can be matched with the rubber roller 19 again, and the rice seeds inside the rectangular vibration disk 3 are leveled again. At the same time, each time the scraper 13 moves, it will be at one end of the rectangular vibration disk 3, which will not affect the suction of the air suction cup 4, and because it slides with the rectangular shell 2, it will not affect the vibration of the rectangular vibration disk 3.

[0047] At the same time, when sowing, the bottom of the support frame 8 can be matched with the existing electric wheel, and the positions of the multiple seedling trays corresponding to the several air suction cups 4 can be arranged in advance, so that as the support frame 8 moves, the several air suction cups 4 can achieve precise sowing of the several seedling trays. This method can be applied in the greenhouse, that is, the seedling trays are laid in the greenhouse in advance. In addition, the support frame 8 can also be installed on the upper side of the existing conveyor belt, and the conveyor belt can accurately transport and position the several seedling trays, so that the several air suction cups 4 can achieve the effect of precise sowing of the several seedling trays on the conveyor belt below. The seedling trays can achieve continuous transportation, and the several air suction cups 4 achieve continuous sowing, realizing high-efficiency sowing production of the seedling trays.

[0048] When the seed adding box 6 is idle or needs to be added with seeds, the electric push rod 11 at the bottom of the seed adding box 6 is started and drives the movable plate 10 to descend, so that the movable plate 10 can close the internal port of the discharge port 7, effectively ensuring the closing effect.

[0049] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
