[0042] In an optional implementation manner of the embodiment of the present invention, as Figure 8 As shown, the scraper 19 is made of stainless steel.

[0043] Working principle: When the present invention is used, firstly, the seeds are placed in the storage box 21, the soil is placed in the feed port 7, and then the seeding plate 27 is clamped in the limiting groove on the bottom plate 26, and the grid 29 is clamped in the limiting groove on the table 28;

[0044] After the preparation work is done, the first step is to lay a layer of soil. The stepper motor II 8 drives the thumbwheel 9 to rotate. The thumbwheel 9 brings out the soil in the feed port 7 and drops it onto the inclined plate 1. Then the stepper motor III 12 drives the eccentric wheel 11 to rotate, thereby driving the inclined plate 1 to move back and forth through the connecting rod 10 to form vibration, so that the soil on the inclined plate 1 slides down smoothly. Then the stepper motor I 6 drives the transmission shaft 5 to rotate, thereby driving the telescopic plate 2 to slide out, so that the telescopic plate 2 slides to the top of the sowing plate 27, and finally the soil falls evenly into the sowing plate 27, and then the telescopic plate 2 is reset;

[0045] In the second step, the cylinder Ⅰ14 is started, driving the telescopic frame Ⅰ15 to slide toward the seeding plate 27, so that the pressure plate 17 moves to the top of the seeding plate 27, and then the cylinder Ⅱ16 drives the pressure plate 17 to move downward, and the stepper motor Ⅳ20 is started, driving the screw rod Ⅰ18 to rotate, thereby driving the scraper 19 to move back and forth, so that the scraper 19 scrapes the soil in the seeding plate 27 flat, and after scraping, the scraper 19 stops moving, and the pressure plate 17 continues to descend to compact the soil. At this time, the scraper 19 will be inserted into the soil. Since the scraper 19 is very thin, it does not affect the flatness of the soil;

[0046] Then the cylinder II 16 drives the pressing plate 17 to rise, and the third step of sowing is performed. There will be a seed in each through hole on the storage box 21, and then the servo motor I 25 is started to drive the screw rod II 24 to rotate, thereby driving the baffle 22 to slide upward, and the upper part of the baffle 22 will cover the through hole on the storage box 21, and push the remaining seeds up to prevent the remaining seeds from falling into the through hole. When the baffle 22 moves, the lower part inserted in the discharge port 23 will be detached, so that the seeds can fall smoothly onto the soil, and then the baffle 22 is reset, and the lower part of the baffle 22 is re-inserted into the notch of the discharge port 23, and the upper part of the baffle 22 slides to expose the through hole again, and another seed will fall into each through hole, and then the position of the telescopic frame I 15 is adjusted, and the above sowing steps are repeated to make the seeds evenly spread on the soil, and then the first step is repeated to spread a layer of soil on the sowing plate 27, and then scrape it flat;

[0047] The fourth step is to insert the grid 29, and the cylinder IV 33 is started to drive the lifting rod 34 to slide downward, so that the clamping claw 35 is clamped at the cross intersection of the grid 29, and then the servo motor II 37 drives the turntable 36 to rotate, so that the arc-shaped notch on the turntable 36 drives the clamping claw 35 to retract inward, thereby clamping the grid 29, and then the lifting rod 34 rises, and then the cylinder III 31 drives the telescopic frame II 32 to slide toward the sowing plate 27, slide to the top of the sowing plate 27, and the cylinder IV 33 drives the lifting rod 34 to move downward again, thereby driving the grid 29 to be inserted into the soil, thereby isolating the seeds and preventing the roots from being mixed up. In this way, sowing is completed, and the sowing plate 27 and the grid 29 are replaced, and the above steps are repeated to quickly complete the sowing of the sowing plate 27.

[0048] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the invention, and the scope of the invention is defined by the appended claims and their equivalents.
