The lower hinge seat 340 is fixedly connected in the lower hole 312 of the seed-leveling frame, and the lower hinge seat 340 is hinged to the cross shaft 350. A cross swing frame 330 is arranged between the cross shaft 350 and the power rod 320, and a cross swing frame shaft 331 is arranged in the middle of the cross swing frame 330. The ball head 332 on the upper part of the cross swing frame shaft 331 is rotatably connected to the ball hole 321 on one side of the power rod 320, and the cross swing frame hinge seat 333 on the lower part of the cross swing frame shaft 331 is hinged to the cross shaft 350. When the second motor 390 rotates, it drives the power rod 320 to rotate, and the rotation of the power rod 320 drives the cross swing frame 330 to rotate. The cross swing frame 330 swings around the axis of the power rod 320 under the action of the lower hinge seat 340 and the cross shaft 350.

[0030] refer to Figures 8 to 11 A seeding plate 360 ​​is disposed at the lower part of the cross swing frame 330, a cross swing frame hole 334 is disposed at each corner of the cross swing frame 330, and four seeding plate fixing rods 363 are disposed at the upper part of the seeding plate 360, and the four seeding plate fixing rods 363 are fixedly connected to the four cross swing frame holes 334 respectively.

[0031] refer to Fig.14 A group of seeding holes 361 corresponding to the acupuncture points of the seed plate 140 are evenly distributed on the end surface of the seeding plate 360. The diameter of the seeding holes 361 is slightly larger than the diameter of the seeds. A seeding plate groove 362 is provided in the middle of the seeding plate 360, and the seeding plate groove 362 is slidably connected to the seeding plate 370.

[0032] refer to Fig.15 The seed placement plate 370 is a hollow structure with an inner cavity 371. The surface of the seed placement plate 370 has a group of seed placement holes 372 and air holes 373 corresponding to the acupuncture points of the seed plate 140. The aperture of the seed placement hole 372 is consistent with the aperture of the seed leveling hole 361, and the aperture of the air hole 373 is smaller than the diameter of the seed. The seed placement hole 372 runs through the seed placement plate 370, and the air hole 373 is connected to the inner cavity. When discharging seeds, the seed placement hole 372 corresponds to the seed leveling hole 361, and when sucking seeds, the seed leveling hole 361 corresponds to the air hole 373.

[0033] refer to Figure 8 The outlet at the bottom of the seeding hole 361 and the inlet at the top of the chassis hole 121 are connected by a hose.

[0034] refer to Fig.15 The inner cavity 371 in the middle of the seed placement plate 370 has an air nozzle 374, and the air nozzle 374 is connected to a vacuum pump.

[0035] refer to Figure 8 The cylinder 380 is connected between the seed-leveling disk 360 and the seed-dropping disk 370, the cylinder body of the cylinder 380 is fixed on the seed-leveling disk 360, and the telescopic rod of the cylinder 380 is fixed on the fixing seat 375 on one side of the seed-dropping disk 370. When leveling the seeds, the seeds are placed in the seed-leveling disk 360, and the vacuum pump connected to the air nozzle 374 is in a working state. The inner cavity 371 is in a negative pressure state, and the seed-leveling hole 361 corresponds to the air hole 373. When the cross swing frame 330 swings, it drives the seed-leveling disk 360 and the seed-dropping disk 370 to swing together. The swinging seed-leveling disk 360 makes the seeds roll around inside the seed-leveling disk 360, and the rolling seeds will randomly fall into the seed-leveling hole 361. The seeds falling into the seed-leveling hole 361 are sucked under the action of the negative pressure and will not fall out due to the swing of the seed-leveling disk 360. After 360 swings several times, all the seed holes 361 will be filled with seeds, and the second motor 390 stops rotating. At this time, the seeds in the seed plate 360 ​​are gathered on one side of the seed plate 360 ​​due to the tilt of the seed plate 360. When the seed plate 140 is pushed to the lower part of the chassis 120, the cylinder 380 acts, the seed plate 370 is pushed, the seed hole 372 is aligned with the seed hole 361, and the seeds in the seed hole 361 fall into the chassis hole 121 through the seed hole 372 and the lower hose, and the seeds fall into each hole of the seed plate 140 through the chassis hole 121. The seedling raising method of the present invention saves time and improves efficiency. The seedling raising method in the hole plate can significantly shorten the seedling raising cycle, thereby improving the production efficiency of poplar seedling raising and reducing labor intensity. Precision sowing can save 30%-50% of the seed consumption and reduce labor costs. The seedling raising method in the hole plate can ensure that each seedling has an independent growth space, avoid competition for water and nutrients, and make the seedlings grow stronger and more neat. At the same time, due to the lack of slow seedling stage and root damage, the survival rate of seedlings after transplanting is high, the seedling slowing period is short, and the spread of pests and diseases is reduced: the "one seed, one nest" mode of seedling cultivation in plug trays reduces the contact between seedlings, thereby reducing the risk of pest and disease transmission. Seedlings grown in plug trays are not easily damaged during transportation, which is conducive to long-distance transportation.

[0036] The invention discloses an operating method of a poplar plantation seedling raising device, comprising the following steps: a first step, when using the device, poplar seeds are placed in a seed leveling plate 360, a vacuum pump connected to an air nozzle 374 is in a working state, the inner cavity 371 is in a negative pressure state, and the seed leveling hole 361 corresponds to the air hole 373; a second step, when the cross swing frame 330 swings, the seed leveling plate 360 ​​and the seed dropping plate 370 are driven to swing together, the swinging seed leveling plate 360 ​​makes the seeds roll around inside the seed leveling plate 360, and the rolling seeds will randomly fall into the seed leveling holes 361, and the seeds falling into the seed leveling holes 361 will be sucked under the action of the negative pressure and will not fall out due to the swinging of the seed leveling plate 360; after the seed leveling plate 360 ​​swings several times, all the seed leveling holes 361 will be filled with seeds, and the second motor 390 stops rotating. The seeds in 360 are gathered on one side of the seeding plate 360 ​​due to the inclination of the seeding plate 360, and then the No. 1 motor 250 is started, and the movable seat 230 moves to the right. When the movable seat 230 moves to the right, the push plate 233 pushes the seeding plate 140 stuck in the lowest part of the four vertical rods 112 to the right. After the seeding plate 140 is pushed out, the movable seat 230 returns. At this time, each position of the chassis hole 121 corresponds to each acupuncture point of the seeding plate 140. When the seeding plate 140 is pushed to the lower part of the chassis 120, the cylinder 380 is actuated, the seeding plate 370 is pushed, and the seeding hole 372 is aligned with the seeding hole 361. The seeds in the seeding hole 361 fall into the chassis hole 121 through the seeding hole 372 and the lower hose, and the poplar seeds fall into each acupuncture point of the seeding plate 140 through the chassis hole 121.

[0037] The swinging cross swing frame 330 drives the seed leveling plate 360 ​​and the seed dropping plate 370 to swing together. The swinging seed leveling plate 360 ​​makes the seeds roll around inside the seed leveling plate 360, and the rolling poplar seeds will randomly fall into the seed leveling holes 361. The swinging of the seed leveling plate 360 ​​not only makes the seeds fall evenly in the seed leveling holes 361, thereby improving the seed leveling speed, but also makes the seeds fall on one side of the seed leveling plate 360 ​​due to the inclination of the seed leveling plate 360 ​​when the seed leveling plate 360 ​​stops swinging, and the seeds will not fall repeatedly. The seeds falling in the seed leveling holes 361 are sucked under the action of negative pressure and will not fall away due to the swinging of the seed leveling plate 360, thereby causing cavitation in the seed leveling holes 361, causing cavitation in the seed plate 140, and affecting the planting effect. The power device 200 not only achieves the purpose of pushing the seed plate 140, but also ensures the relative position of the seed plate 140 and the upper chassis 120, thereby ensuring that the seeds can fall into each hole of the seed plate 140.
