A limiting groove 74 corresponding to the limiting plate 73 is provided on the upper end of the bottom plate 1, and a plurality of fixing holes 75 are provided on the side of the limiting groove 74.

[0024] By adopting the above technical solution, when it is necessary to adjust the spacing of the seeder body 4, first release the limit of the fixing component 72 on the limit plate 73, and then slide the seeder body 4, the seeder body 4 drives the slider 71 to slide in the slide groove 76, and at the same time, the seeder body 4 drives the limit plate 73 to slide inside the limit groove 74, thereby realizing the spacing adjustment of the seeder body 4.

[0025] Specifically, the fixing assembly 72 includes a fixing rod 721 and a spring 722. The spring 722 is disposed inside the limiting plate 73, and the fixing rod 721 is disposed at the other end of the spring 722.

[0026] By adopting the above technical solution, when it is necessary to adjust the spacing of the seeder body 4, the adjustment block 724 inside the sliding adjustment groove 723 is driven, and the adjustment block 724 drives the fixing rod 721 to compress the spring 722 and embed it into the inside of the limit plate 73, and then the seeder body 4 is slid, and the seeder body 4 drives the slider 71 to slide inside the slide groove 76. After adjusting the spacing of the seeder body 4, the adjustment block 724 is released, and the spring 722 rebounds, thereby driving the fixing rod 721 to insert into the designated fixing hole 75 to fix the seeder body 4.

[0027] Specifically, the fixing assembly 72 further includes an adjusting slot 723 and an adjusting block 724. The upper end of the fixing rod 721 is provided with an adjusting block 724.

[0032] By adopting the above technical solution, the seeds are poured into the interior of the seeder body 4 through the feed port 6, and the solenoid valve 81 is opened. After the solenoid valve 81 is opened, the seeds on the upper end of the partition 89 will enter the upper end of the weighing plate 82 through the discharge pipe 810 until they slide to the upper end of the baffle 84. The seeds that fall onto the baffle 84 are monitored by the weighing module 85 at the lower end of the baffle 84. When the weight of the seeds exceeds the threshold set by the PLC controller 86, the weighing module 85 transmits the monitoring signal to the PLC controller 86. The PLC controller 86 issues an instruction to control the solenoid valve 81 to close, and at the same time controls the electric push rod 83 to start. The electric push rod 83 drives the baffle 84 to slide, so that the seeds are discharged through the discharge port 9 to achieve the purpose of quantitative automatic sowing.

After the solenoid valve 81 is opened, the seeds on the upper end of the partition 89 will enter the upper end of the weighing plate 82 through the discharge pipe 810 until they slide to the upper end of the baffle 84. The seeds that fall onto the baffle 84 are monitored by the weighing module 85 at the lower end of the baffle 84. When the weight of the seeds exceeds the threshold set by the PLC controller 86, the weighing module 85 transmits the monitoring signal to the PLC controller 86. The PLC controller 86 issues an instruction to control the solenoid valve 81 to close, and at the same time controls the electric push rod 83 to start. The electric push rod 83 drives the baffle 84 to slide, so that the seeds are discharged through the discharge port 9 to achieve the purpose of quantitative automatic sowing.

After adjusting the spacing of the seeder body 4, the adjustment block 724 is released, and the spring 722 rebounds, thereby driving the fixing rod 721 to insert into the designated fixing hole 75 to fix the seeder body 4; the seeds are poured into the inside of the seeder body 4 through the feed port 6, Open the solenoid valve 81. After the solenoid valve 81 is opened, the seeds on the upper end of the partition 89 will enter the upper end of the weighing plate 82 through the discharge pipe 810 until they slide to the upper end of the baffle 84. The seeds that fall onto the baffle 84 are monitored by the weighing module 85 at the lower end of the baffle 84. When the weight of the seeds exceeds the threshold set by the PLC controller 86, the weighing module 85 transmits the monitoring signal to the PLC controller 86. The PLC controller 86 issues an instruction to control the solenoid valve 81 to close, and at the same time controls the electric push rod 83 to start. The electric push rod 83 drives the baffle 84 to slide, so that the seeds are discharged through the discharge port 9 to achieve the purpose of quantitative automatic sowing.
