In summary, the working principle of the integrated seeding apparatus for vegetable planting in the embodiment in the specific working process is specifically described as follows:
the first stage is as follows: when the seeder works, a tractor drives the whole seeding equipment to advance through the traction frame 1, the power main shaft 15 of the lifting driving mechanism drives the eccentric wheel 16 to rotate, the eccentric shaft of the eccentric wheel 16 rotates from the highest point to the low point, the eccentric shaft drives the lifting frame 13 to descend through the groove-shaped guide rail 17, the lifting frame 13 drives the lifting arm 3 and the seeding pipe 2 which are installed on the lifting frame to descend, and the soil opener at the bottom end of the seeding pipe 2 is inserted into soil.
And a second stage: during the process that the eccentric shaft of the eccentric wheel 16 continuously rotates from the low position to the lowest point, the soil opener is inserted into the soil and continuously descends. Meanwhile, the rotating shaft 20 of the pressing driving mechanism synchronously drives the pressing head 22 to rotate from the low position to the lowest point, and since the turning radius of the pressing head 22 is greater than that of the eccentric shaft, the pressing head 22 contacts with the pressing driving frame 18 at the moment and pushes the pressing driving frame 18 to move downwards, and the pressing driving frame 18 with the seeding pipe 2 and the core body control rod 1006 connected with the pressing driving frame descends to the following state: 1. the seeding pipe 2 and the lifting arm 3 slide relatively, so that the soil opener is driven to open, soil is raked to form a seed hole, and the lower port of the seeding pipe 2 is opened to enable seeds in the pipe to fall into the seed hole; 2. the core operation rod 1006 drives the outer core 1002 to slide from top to bottom to close the second runner opening and open the first runner opening, and the seeds in the seed box 9 fall into the runner 1003 from the first runner opening.
And a third stage: the eccentric shaft of the eccentric wheel 16 rotates from the lowest point to a lower position which is slightly higher, the lifting frame 13 is driven to rise, the pressure spring 8 on the lifting arm 3 and the return spring 19 on the lifting frame 13 provide upward elastic force, so that the sowing pipe 2 and the pressing driving frame 18 also move upwards, but the soil opener cannot completely leave the soil in the process. Meanwhile, the rotating shaft 20 synchronously drives the pressing head 22 to rotate from the lowest point to a slightly higher low position, in the process, the pressing driving frame 18 still abuts against the lower end of the pressing head 22 under the action of elastic force, and only when the pressing head 22 continues to rotate upwards and is separated from the pressing driving frame 18 again, the pressing driving frame 18 and the sowing pipe 2 can be completely reset and the soil opener is closed again, so that the soil opener in the stage is in a state of rising and slowly closing. It is worth mentioning that in the closing process of the soil opener, the soil in the shovel body 7 is accumulated towards the middle, and along with the rising of the soil opener, the soil inside the shovel body 7 falls off, so that the effect of covering the seed holes with soil again is achieved.
A fourth stage: with the eccentric shaft of the eccentric wheel 16 and the pressing head 22 continuing to rotate upwards, at this time, the pressing head 22 is completely separated from the pressing driving frame 18, the pressing driving frame 18 and the sowing pipe 2 are completely reset, the soil opener is closed again, meanwhile, the pressing driving frame 18 drives the core body control rod 1006 to drive the outer core body 1002 to slide from bottom to top to a position where the first flow passage opening is closed, at this time, the second flow passage opening is opened, and seeds in the flow passage 1003 flow into the sowing pipe 2 again to prepare for next planting.
The fifth stage: the eccentric shaft of the eccentric wheel 16 comes to the highest position again, the lifting arm 3 and the seeding tube 2 are completely separated from the soil and return to the highest position again, and four steps of soil breaking, hole opening, seeding and soil covering are completed. When the tractor pulls to advance and then plants the next time, the two planting positions generate a spacing distance. All planting work can be completed by circulating the steps.
