Fig. 9As shown, the rotating disc 6 is connected with a rotating collection mechanism and a pushing and sowing mechanism, and the seedling seeds are sequentially transported to the corresponding placement holes 7 through the action of the rotating collection mechanism, and the movable frame 5 is connected with a front ridge grooving mechanism and a moving soil covering mechanism; when working, the prior art usually uses a sowing device for automatic sowing when sowing seedlings, and the sowing device is moved by the sowing personnel to sow the seedling seeds in the nursery ground, but in the actual operation process, since the sowing speed of the automatic sowing device remains unchanged, the sowing speed of the seedling seeds cannot be changed in real time according to the actual moving speed of the sowing device, thereby affecting the uniformity of the distribution of the seedling seeds in the nursery ground and reducing the sowing effect of the seedling seeds; the technical solution can solve the above problems, and the specific working method is as follows: when the seedling seeds are sown, the movable frame 5 is moved vertically downward by the action of the vertical lifting mechanism, and the rotating disc 6 is driven to move downward, and the rotating disc 6 is elastically pressed against the ground by the action of the elastic giving way mechanism, and then the fixed frame 2 is driven to move by the tractor 1, and the rotating disc 6 on the fixed frame 2 is The movable roller 4 rotates in coordination on the ground, and when the fixed frame 2 drives the movable frame 5 to move horizontally, the front ridge grooving mechanism moves and grooves on the ground, and the rotating disc 6 rolls in contact in the groove by elastic pressure, and in the rolling process, the seedling seeds are transported to the corresponding placement holes 7 for collection in sequence by the action of the rotating collection mechanism, and when the placement holes 7 rotate to the bottom of the rotating disc 6 as the rotating disc 6, the seedling seeds are pushed out of the corresponding placement holes 7 by the action of the pushing sowing mechanism and remain in the groove, and then the soil on both sides of the groove is pushed into the groove by the action of the soil covering mechanism to bury the seedling seeds in the groove, when sowing the seedling seeds, the rotating disc 6 contacts the ground and rotates in coordination with the movement of the fixed frame 2, and in the process of rotation, the seedling seeds are transported to the corresponding placement holes 7 and then rotated for sowing, so that the sowing speed of the seedling seeds can be changed in real time according to the actual moving speed of the sowing equipment, reducing the distance change between adjacent seedlings, and improving the uniformity and sowing effect of sowing the seedling seeds.

[0024] As a further embodiment of the present invention, the elastic yielding mechanism comprises a mounting frame 8 and two limiting rings 9, wherein the mounting frame 8 is arranged between the movable frame 5 and the rotating disk 6. Figure 5 As shown, the bottom of the mounting frame 8 is fixedly connected to two second support rods 10, a rotating shaft 11 is fixedly connected between the two second support rods 10, the rotating disc 6 is rotatably connected to the rotating shaft 11, and two limit rings 9 are fixedly connected to both sides of the inside of the movable frame 5, as shown in FIG.

When the movable frame 5 moves vertically downward, the rotating disk 6 moves downward. When the rotating disk 6 contacts the ground and the movable frame 5 continues to move downward, the limit pins 12 on the top of the mounting frame 8 move along the sliding insertion of the limit ring 9, thereby squeezing the springs 13 to produce compression deformation, so that the rotating disk 6 elastically gives way when the movable frame 5 continues to move downward, and the rotating disk 6 is elastically pressed against the ground through the elastic extension effect generated by the compression of the spring 13.

[0025] As a further embodiment of the present invention, the rotating collection mechanism includes a storage cylinder 14 and a limit stop ring 15. The storage cylinder 14 is fixedly connected to the mounting frame 8. The limit stop ring 15 is rotatably sleeved on the rotating disc 6 and fixedly connected to the mounting frame 8. The bottom of the storage cylinder 14 is fixedly connected to a feeding pipe 16. The bottom end of the feeding pipe 16 is fixedly connected to the top of the limit stop ring 15. The bottom of the limit stop ring 15 is provided with a discharge groove 17. Fig.10 As shown, two groups of anti-skid feet 18 are fixedly connected to the surface of the rotating disk 6 along the circumferential direction, and the two groups of anti-skid feet 18 are respectively located on both sides of the limit ring 15; when working, when the rotating disk 6 contacts the ground and rotates along the rotating connection of the rotating shaft 11, the two groups of anti-skid feet 18 rotate synchronously with the rotating disk 6, and are inserted into the ground during the rotation process to perform anti-skid operations, thereby improving the contact rotation efficiency of the rotating disk 6, placing the seedlings and seeds inside the storage tube 14, and the seedlings and seeds enter the feeding tube 16 along the storage tube 14, and when the rotating disk 6 rotates along the inside of the limit ring 15, the rotating disk 6 rotates. The placement holes 7 on the disc 6 rotate to the bottom of the connection between the feeding tube 16 and the limit stop ring 15, so that the seedling seeds at the bottom of the feeding tube 16 fall into the corresponding placement holes 7 under the action of gravity, so that under the rotation of the rotating disc 6, the seedling seeds enter the corresponding placement holes 7 in turn. When the seedling seeds in the placement holes 7 rotate to the discharge groove 17 at the bottom of the limit stop ring 15 along with the rotating disc 6, the placement holes 7 lose the blocking limit of the limit stop ring 15, and under the action of the pushing sowing mechanism, the seedling seeds in the placement holes 7 are pushed out along the discharge groove 17, thereby completing the sowing of the seedling seeds.

[0026] As a further embodiment of the present invention, the push-feeding sowing mechanism includes a plurality of push pins 19, which are respectively slidably inserted into the corresponding placement holes 7, a plurality of movable grooves 20 are provided on one side of the rotating disc 6, and the movable grooves 20 are respectively connected to the corresponding placement holes 7, and the push pins 19 are fixedly connected with movable bars 21, and one end of the movable bar 21 extends along the corresponding movable groove 20 to one side of the rotating disc 6 and is fixedly connected with a circular pin 22, and a fixed bracket 23 is fixedly connected to the rotating shaft 11.

Fig.12 As shown, it includes an inner arc segment 2501 and an outer arc segment 2502, and the outer arc segment 2502 is located at the bottom of the guide groove 25; when working, when the rotating disc 6 rotates and collects the seedlings into the corresponding placement hole 7, the seedlings are supported by one end of the push pin 19 and the placement hole 7 is kept in the collection space of a single seedling. During the rotation of the rotating disc 6, the circular pin 22 moves along the inside of the guide groove 25, and when the placement hole 7 rotates to the inside of the discharge trough 17, the circular pin 22 moves along the inner arc segment 2501 to the outer arc segment 2502, so that The movable bar 21 moves along the movable groove 20, and makes one end of the pushing pin 19 move along the placement hole 7 toward the surface of the rotating disk 6, so that the seedling seeds inside the placement hole 7 are pushed out from the placement hole 7 and fall to the ground along the discharge groove 17 for sowing. When the circular pin 22 moves from the outer arc segment 2502 to the inner arc segment 2501 again, the pushing pin 19 returns to the initial position so that the placement hole 7 can continue to collect seedling seeds. The movable groove 20 and the guide groove rail 25 are shielded by the annular shell 24 to prevent the entry of dirt and dust, thereby ensuring the normal movement of the movable bar 21 and the circular pin 22.

[0030] As a further embodiment of the present invention, the driving flipping mechanism includes a second hydraulic cylinder 34 and a fixed shaft 35. The second hydraulic cylinder 34 is fixedly installed on the fixed rod 30, and the fixed shaft 35 is fixedly connected to the other end of the flipping rod 33.

[0031] As a further embodiment of the present invention, the soil-covering mechanism includes a U-shaped plate 38, which is fixedly connected to the bottom of the movable frame 5 and located between the tractor 1 and the rotating disc 6. The interior of the U-shaped plate 38 is rotatably connected to a connecting shaft 39. Figure 2 As shown, two spiral blades 40 are fixedly connected to the connecting shaft 39, and the two spiral blades 40 are in contact with each other and have opposite spiral directions. A driving mechanism is connected to the connecting shaft 39.

The rotating disc 6 can be elastically pressed against the ground by the elastic giving way mechanism. Then, the fixed frame 2 is driven to move by the tractor 1, and the rotating roller 4 on the fixed frame 2 rotates on the ground. When the fixed frame 2 drives the movable frame 5 to move horizontally, the front ridge grooving mechanism is used to move and groove on the ground. The rotating disc 6 rolls in contact in the groove by elastic pressure, and in the rolling process, the seedlings are transported to the corresponding placement holes 7 for collection in sequence by the rotating collection mechanism, and the rotating rollers 4 on the placement holes 7 rotate in coordination with the rotating rollers 4 on the ground. When the rotating disc 6 rotates to the bottom of the rotating disc 6, the seedling seeds are pushed out of the corresponding placement holes 7 and left in the grooves by the action of the pushing sowing mechanism, and then the soil on both sides of the grooves is pushed into the grooves by the action of the soil covering mechanism to bury the seedling seeds in the grooves. When the seedling seeds are sown, the rotating disc 6 contacts the ground and rotates with the movement of the fixed frame 2, and the seedling seeds are transported to the corresponding placement holes 7 during the rotation process and then rotated for sowing, so that the sowing speed of the seedling seeds can be changed in real time according to the actual moving speed of the sowing equipment, reducing the distance change between adjacent seedlings, and improving the uniformity and sowing effect of the seedling seeds.
