The conveyor belt is sleeved on the outer sides of the driving roller 14 and the driven roller 15. The driving motor 13 and the driving roller 14 are driven by a transmission belt. The driving motor 13 drives the driving roller 14 to rotate, thereby driving the conveyor belt to roll, so as to realize the movement of the culture vessel 40 from the feeding end 10a to the discharging end 10b.

[0043] Specifically, a material blocking module 16 is arranged on the connecting frame 11, and the material blocking module 16 includes a push cylinder 161 fixed on the connecting frame 11, and a material blocking block 162 fixed to the driving end of the push cylinder 161.

[0044] Specifically, relatively arranged inductive switches are provided on the connecting frame 11, and the inductive ends of the inductive switches face the conveyor belt 12; further, a first inductive switch 17a and a second inductive switch 17b are provided; the first inductive switch 17a is provided in the sowing station 10c, and is used to sense whether the cultivation vessel 40 is moved into the sowing station 10c; the second inductive switch 17b is provided at one end of the sowing station 10c close to the discharge end 10b, and is used to sense that the cultivation vessel 40 leaves the sowing station 10c.

[0045] See alsoFigure 7 On one side of the tray 20, an installation part 21 extends, and a vibrator 22 is connected to the installation part 21. Before sucking seeds, the vibrator 22 drives the tray 20 to vibrate; under the action of vibration, the seeds on the tray 20 are dispersed, so as to be sucked by the material sucking module 33. In this embodiment, the vibrator 22 is a pneumatic piston vibrator 22.

[0046] Please refer to Figure 5 and Figure 6 , the seeding mechanism 30 includes a connecting plate 31, a driving module 32 drivingly connected to the connecting plate 31, and a plurality of material sucking modules 33 assembled on the connecting plate 31.

The assembly grooves 311 are arranged corresponding to the cultivation grooves 41. The material sucking modules 33 are assembled into the assembly grooves 311. A first through hole 312 is formed at the bottom of the assembly groove 311, and the lower end of the material sucking module 33 extends out through the first through hole 312. In actual use, the material sucking module 33 can be disassembled or installed in the assembly groove 311, so the number of the material sucking modules 33 can be adjusted according to the cultivation grooves 41 of the cultivation vessel 40. In addition, a cover plate 34 is provided at the upper end of the connecting plate 31. A plurality of second through holes 341 are formed on the cover plate 34. The second through holes 341 are arranged corresponding to the assembly grooves 311. The upper end of the material sucking module 33 passes through the second through holes 341. The specific assembly sequence is as follows: put the material sucking module 33 into the assembly groove 311, place the cover plate 34 on the connecting plate 31, and lock the cover plate 34 and the connecting plate 31 with bolts; it should be noted that the second through holes 341 are smaller than the openings of the assembly grooves 311. After assembly, the material sucking module 33 will be fixed in the assembly groove 311.

[0048] Among them, the material sucking module 33 includes a connecting seat 331 and a material sucking needle 332; the material sucking needles 332 are uniformly distributed at the lower end of the connecting seat 331, and an air pipe joint 333 is provided at the upper end of the connecting seat 331; the air pipe joint 333, the connecting seat 331 and the inside of the material sucking needle 332 are in mutual communication. The air pipe joint 333 is externally connected to an air pipe and connected to a vacuum pump through the air pipe. When seeds need to be sucked, the vacuum pump creates negative pressure in the material sucking needle 332. Under the action of the negative pressure, the seeds are sucked into the material sucking needle 332; on the contrary, when sowing, the vacuum pump stops working. After the negative pressure is released, the seeds fall off from the material sucking needle 332 and fall into the cultivation groove 41 to complete sowing.

[0049] Among them, the driving module 32 includes a driving cylinder 321 and a connecting rod assembly 322; the connecting rod assembly 322 includes a T-shaped movable frame 3221, first connecting rods 3222 rotatably connected to both sides of the movable frame 3221, second connecting rods 3223 arranged in parallel with the first connecting rods 3222, and a third connecting rod 3224 arranged horizontally; the upper ends of the first connecting rods 3222 and the second connecting rods 3223 are rotatably connected to the connecting plate 31, and the lower ends of the first connecting rods 3222 and the second connecting rods 3223 are rotatably connected to the third connecting rod 3224. The first connecting rods 3222, the second connecting rods 3223, the third connecting rod 3224, and the connecting plate 31 form a parallelogram structure. In addition, the third connecting rod 3224 is in a fixed state. Therefore, when the driving cylinder 321 retracts, the connecting plate 31 will swing towards the discharging end 10b, and conversely, when the driving cylinder 321 extends, the connecting plate 31 will swing towards the feeding end 10a.

[0050] Please refer to Figures 1 to 2 , and further includes a support frame 50. The conveying mechanism 10 is assembled at the upper end of the support frame 50; a machine cover 60 is provided on the support frame 50. The machine cover 60 covers the conveying mechanism 10 from above, and the material tray 20 and the connecting plate 31 are arranged inside the machine cover 60.

[0051] The working principle of the automatic seeding machine involved in the present utility model is as follows:

[0052] The driving cylinder 321 retracts, driving the material suction module 33 to move to the material tray 20, and at the same time, the vibrator 22 vibrates the material tray 20. Subsequently, the material suction module 33 sucks the seeds; when the first induction switch 17a senses the cultivation vessel 40, the driving cylinder 321 extends, driving the material suction module 33 to move into the cultivation groove 41 and perform seeding.

[0053] Compared with the prior art, the automatic seeding machine involved in the present utility model includes a conveying mechanism 10, a material tray 20, and a seeding mechanism 30; the conveying mechanism 10 moves the cultivation vessel 40 to the seeding station 10c, and the seeding mechanism 30 automatically sucks the seeds in the material tray 20 and moves to the designated position in the cultivation vessel 40 for seeding; the seeding efficiency is improved, and at the same time, the seeding position can be controlled to meet the seeding requirements; specifically, the seeding mechanism 30 includes a connecting block and a plurality of material suction modules 33. The material suction modules 33 suck or release the seeds by means of vacuum adsorption, further improving the efficiency. In addition, a plurality of material suction modules 33 are provided, which can seed multiple cultivation vessels 40 simultaneously; in addition, the seeding mechanism 30 uses a cylinder and a connecting rod in cooperation to drive the reciprocating movement of the material suction module 33 between the material tray 20 and the cultivation vessel 40, and mechanical control is used to improve the movement accuracy, thereby controlling the seeding position and improving the seeding accuracy.

[0054] The above only expresses the preferred technical solutions of the present utility model, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and the present utility model also intends to include these modifications and variations.
