[0040] In a preferred embodiment, the connecting rod transmission mechanism includes a first connecting rod 5, a second connecting rod 7, a third connecting rod 9, a first rotating shaft 3, a second rotating shaft 6, a third rotating shaft 8 and a fourth rotating shaft 10; the lower end of the depth adjustment rod 2, the upper end of the furrow opener 4, and one end of the first connecting rod 5 are all fixedly connected to the first rotating shaft 3, and the first rotating shaft 3 is rotatably connected to the main frame 1; the other end of the first connecting rod 5 is rotatably connected to one end of the second connecting rod 7 through the second rotating shaft 6; the other end of the second connecting rod 7 is rotatably connected to the third connecting rod 9 through the third rotating shaft 8; one end of the third connecting rod 9 is rotatably connected to the main frame 1 through the fourth rotating shaft 10, and the other end of the third connecting rod 9 is connected to the soil covering and pressing wheel assembly 11.
[0041] In this embodiment, the first connecting rod 5, the depth adjustment rod 2, the furrow opener 4 and the first rotating shaft 3 are fixedly connected to each other. Under the action of the depth adjustment rod 2, the furrow opener 4 and the second connecting rod 7 can rotate around the first rotating shaft 3 relative to the main frame 1, thereby driving the second rotating shaft 6 to swing around the first rotating shaft 3. While the second connecting rod 7 on the second rotating shaft 6 swings with the second rotating shaft 6, it will drive the third rotating shaft 8 to move, so that the third rotating shaft 8, the third connecting rod 9 and the soil covering and pressing wheel assembly 11 rotate together around the fourth rotating shaft 10 on the main frame 1 to achieve the adjustment of the soil covering wheel.
[0042] Specifically, Figure 1 Taking the perspective in as an example, when the depth adjustment rod 2 rotates counterclockwise around the first rotating shaft 3, the furrow opener 4 and the first connecting rod 5 and the second rotating shaft 6 all rotate counterclockwise around the first rotating shaft 3, and the second connecting rod 7 moves to the upper right, driving the third rotating shaft 8, the third connecting rod 9 and the covering and pressing wheel assembly 11 to rotate counterclockwise around the fourth rotating shaft 10, thereby realizing the synchronous lifting and lowering of the furrow opener 4 and the covering wheel.
[0043] In a preferred embodiment, the linkage mechanism also includes an elastic member 13, one end of the elastic member 13 is connected to the main frame 1, and the other end of the elastic member 13 is connected to the soil covering and pressing wheel assembly 11, and the elastic member 13 is used to apply a forward force to the soil covering and pressing wheel assembly 11.
[0044] In this embodiment, by providing the elastic member 13, a force acting in the direction of the furrow opener 4 can be applied to the soil covering and pressing wheel, so that the soil covering wheel can adapt to different ground surfaces and always maintain a soil covering state.
[0045] In this embodiment, the elastic member 13 can be a compression spring, a tension spring, or a torsion spring, which is configured according to a specific design structure as long as it can apply a forward force to the soil covering and pressing wheel assembly 11 .
[0046] In a preferred embodiment, a plurality of adjustment holes are provided on the main frame 1 , and the elastic member 13 is connected to the main frame 1 through any one of the adjustment holes.
[0047] In this embodiment, after a plurality of adjustment holes are provided on the main frame 1, the elastic member 13 can be connected to different adjustment holes to adjust different pressures of the elastic member 13, thereby adjusting the size and direction of the force applied to the soil covering and pressing wheel assembly 11.
[0048] Specifically, in the present embodiment, there are two adjustment holes, namely a first adjustment hole 14 and a second adjustment hole 15. The first adjustment hole 14 and the second adjustment hole 15 are respectively arranged on opposite sides of the fourth rotating shaft 10, and the first adjustment hole 14 and the second adjustment hole 15 have different heights, so that forces of different sizes and directions can be applied to the soil covering and pressing wheel assembly 11.
[0049] In a preferred embodiment, a strip groove 16 is provided on the second connecting rod 7 , and the third rotating shaft 8 is slidably disposed in the strip groove 16 .
[0050] In this embodiment, the strip groove 16 can make the movement of the second connecting rod 7 more flexible, and can cooperate with the elastic member 13 at the position of different adjustment holes to adjust the position of the soil covering and pressing wheel assembly 11, further ensuring the stability of the depth of the soil covering layer.
[0051] In this embodiment, the length direction of the strip groove 16 is consistent with the length direction of the second connecting rod 7 .
[0052] In a preferred embodiment, Figure 4 As shown, the first connecting rod 5 , the second connecting rod 7 and / or the third connecting rod 9 are provided with a bent edge 19 .

[0054] Bending edges 19 are provided on the first connecting rod 5, the second connecting rod 7 and the third connecting rod 9. The provision of the bending edges 19 can enhance the strength of the first connecting rod 5, the second connecting rod 7 and the third connecting rod 9, thereby ensuring the transmission stability of the connecting rod transmission mechanism.
[0055] It can be understood that the first connecting rod 5, the second connecting rod 7 and the third connecting rod 9 can all be provided with the bending edge 19, or one or two of them can be provided with the bending edge 19, as long as the strength during use can be guaranteed.
[0056] In a preferred embodiment, a limiting structure is provided on the main frame 1 for limiting the depth adjustment rod 2 at different positions.
[0057] In this embodiment, a limiting structure is provided on the main frame 1. Through the setting of the limiting structure, the position of the depth adjustment rod 2 can be limited, which not only ensures the stability of the depth adjustment rod 2, but also can adjust the different positions of the depth adjustment rod 2, thereby achieving the adjustment of the depth of the furrow opener 4 and the height of the covering wheel.
[0058] In a preferred embodiment, Figure 3 As shown, the limiting structure includes a limiting frame 17 ; the depth adjustment rod 2 swings in the limiting frame 17 ; a plurality of limiting grooves 18 are arranged on the inner wall of the limiting frame 17 , and the depth adjustment rod 2 can be arranged in the limiting grooves 18 .

The depth adjustment rod 2 passes through the limiting frame and can swing back and forth in the limiting frame 17, thereby driving the furrow opener 4 to move in the up and down directions.
[0060] Specifically, in this embodiment, a plurality of limit grooves 18 are provided inside the limit frame 17. When the depth adjustment rod 2 is swung to a certain position, it can be inserted into the limit groove 18. By cooperating with the limit groove 18, the depth adjustment rod 2 is positioned in the limit frame 17.
[0061] In a preferred embodiment, the linkage mechanism further includes a scraper plate 12 , which is disposed on the soil covering and pressing wheel assembly 11 and is used to remove soil on the soil covering and pressing wheel assembly 11 .
[0062] In this embodiment, the scraper blade 12 is arranged at the rear end of the pressing wheel assembly in the figure, that is, the end away from the furrow device 4, which can remove the dirt, weeds and other debris stuck on the outer wall of the covering wheel to a certain extent, thereby ensuring that the covering wheel can rotate normally.
[0063] Specifically, in this embodiment, the thickness of the lower end of the scraper blade 12 is less than the thickness of the upper end, or the lower end of the scraper blade 12 has a cutting edge.
[0064] Such an arrangement can better remove dirt, weeds and other debris from the covering wheel, ensuring the normal rotation of the covering wheel.
[0065] It can be seen from the above content that the linkage mechanism provided by the utility model has the following specific operation process:
[0066] When the operating depth adjustment lever 2 moves up and down, it rotates around the first rotating shaft 3 to drive the furrow opener 4 to swing, thereby realizing the adjustment change of the furrowing depth, and then the first connecting rod 5 is rotated at the position of the second rotating shaft 6 to connect the second connecting rod 7, driving the third rotating shaft 8 on the soil covering and pressing wheel assembly 11, so that the soil covering and pressing wheel assembly 11 rotates around the fourth rotating shaft 10, so that the height of the soil covering wheel on the soil covering and pressing wheel assembly 11 moves up and down synchronously with the up and down movement of the furrow opener 4, so that the furrowing depth and the soil covering position of the soil covering wheel can be controlled and adjusted.
[0067] In addition, by changing the hanging point position of the elastic member 13, that is, connecting the elastic member 13 to different adjustment holes, the pressing position of the covering wheel can be stabilized, and appropriate adaptive adjustment can be made as the soil surface fluctuates.
[0068] When the target planting depth is greater than 50 mm, the hanging point of the elastic member 13 is the first adjustment hole 14 , and when the planting depth is less than or equal to 50 mm, the hanging point of the elastic member 13 is the second adjustment hole 15 , wherein, during the initial setting, the spring hanging point is the second adjustment hole 15 .
[0069] Secondly, the utility model further provides a transplanter, which includes any of the linkage mechanisms described above.
[0070] The beneficial effects of the embodiments of the utility model are:
[0071] The furrow opener 4 and the soil covering and pressing wheel assembly 11 are connected as a whole through a connecting rod mechanism, so that they can be raised and lowered synchronously. Therefore, when the depth of the furrow opener 4 is adjusted, the height of the soil covering and pressing wheel can be adjusted synchronously, thereby ensuring the stability between the planting depth and the depth of the soil covering layer during transplanting, improving the survival rate of seedlings, and reducing the cost of transplanting and seedling use.
[0072] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes.
