Description

Technical Field

[0001] This invention relates to the field of hydroponic vegetable cultivation technology, specifically to an automated hydroponic vegetable sowing device. Background Technology

[0002] Hydroponic vegetables refer to vegetables whose roots mostly grow in a nutrient solution layer, and which are provided with water, nutrients and oxygen only by the nutrient solution. They are of high quality, have a sweet taste, and high yield, and meet the standards of green vegetables. They can also be grown in multiple crops, which improves land utilization and achieves pollution-free vegetables, thus effectively promoting agricultural efficiency and income growth.

[0003] In hydroponic vegetable cultivation, seeds must first be placed inside a planting plate for hydroponic growth. However, most current seeding devices require manual sowing, which can lead to operator fatigue over long periods, resulting in decreased efficiency. Furthermore, most seeding devices are prone to deviations, causing seeds to fail to accurately enter the planting holes of the planting plate, requiring manual re-insertion and further impacting sowing efficiency. To address these issues, the inventor proposes an automated hydroponic vegetable seeding device. Summary of the Invention

[0046] By adopting the above technical solution, the fourth screw 505 can install the rectangular plate 501.

[0047] A movable block 317 is slidably installed inside the mounting plate 302 on the right side, and the end of the connecting strip 503 away from the movable plate 502 is movably locked inside the movable block 317. A third screw 318 is rotatably installed inside the mounting plate 302 on the right side, and the movable block 317 is threaded onto the third screw 318.

A third gear plate 323 is fixedly installed inside the side plate of the fixing bracket 301 near the mounting rod 319, and the third gear plate 323 and the second gear 322 are movably meshed.

[0048] By adopting the above technical solution, the moving block 317 can drive the moving plate 502 to move.

[0049] Working principle: First, place the planting board on the feeding platform 101, turn on the electric cylinder 102 to drive the push plate 103 to move. The movement of the push plate 103 drives the planting board to move onto the square plate 401. At this time, when the planting board passes through the support frame 201, the nozzle 205 sprays nutrient solution onto the upper surface of the planting board to facilitate subsequent seed cultivation.

[0050] Secondly, the movement of the push plate 103 drives the first toothed plate 107 to move. The meshing of the first toothed plate 107 and the first gear 106 drives the first gear 106 to rotate. The rotation of the first gear 106 drives the transmission rod 105 to rotate. The rotation of the transmission rod 105 drives the mounting rod 319 to rotate. The rotation of the mounting rod 319 drives the second screw 316 to rotate. The rotation of the second screw 316 drives the limiting block 315 to move. The movement of the limiting block 315 drives the moving frame 314 to move. The movement of the moving frame 314 drives the seeds inside the moving frame 314 to move, so that the seeds pass through the rectangular plate 501 and enter the placement hole of the rectangular plate 501.

[0051] Then, when the push plate 103 returns to its original position, the motor 312 is turned on, driving the rotating rod 309 to rotate. The rotation of the rotating rod 309 drives the fourth bevel gear 311 to rotate, which in turn drives the third bevel gear 310 to rotate. The rotation of the third bevel gear 310 drives the rotating rod 306 to rotate, which in turn drives the second bevel gear 307 to rotate. The rotation of the second bevel gear 307 drives the first bevel gear 305 to rotate, which in turn drives the first screw 304 to rotate. The rotation of the first screw 304 drives the slider 303 to move, which in turn drives the mounting plate 302 to move. The movement of the mounting plate 302 drives the rectangular plate 501 to move, and the movement of the rectangular plate 501... The guide tube 506 is moved so that it is inserted into the planting hole of the planting plate. At this time, the movement of the mounting plate 302 on the right side causes the fixing block 320 to move. The movement of the fixing block 320 causes the bottom end of the second tooth plate 321 to move. The meshing of the second tooth plate 321 and the third gear 405 causes the third gear 405 to rotate. The rotation of the third gear 405 causes the double-headed screw 404 to rotate. The rotation of the double-headed screw 404 causes the slide bar 403 to move. The movement of the slide bar 403 causes the moving bar 402 to move. The movement of the moving bar 402 causes the moving seat 406 to move. The movement of the moving seat 406 causes the limiting wheel 412 to move, so that the outer surface of the limiting wheel 412 contacts the outer surface of the planting plate, thereby positioning the planting plate.

[0052] Finally, the movement of the mounting plate 302 drives the movement of the third screw 318, which in turn drives the movement of the second gear 322. When the second gear 322 meshes with the third gear plate 323, it rotates, which in turn drives the third screw 318 to rotate. This rotation then drives the moving block 317 to move, which in turn drives the connecting strip 503 to move. The movement of the connecting strip 503 then drives the moving plate 502 to move, aligning the holes in the moving plate 502 with the placement holes in the rectangular plate 501 and the guide tube 506. At this point, the seeds inside the placement holes of the rectangular plate 501 fall through the holes in the moving plate 502 into the guide tube 506, and then enter the planting holes of the planting plate through the guide tube 506, completing the sowing process.

Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
