[0020] The invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] like Figure 1-Figure 4As shown, the seeding device of the seeding line of the present embodiment, which can adapt to seeding of different crops, comprises a drum-type seeding device housing 5 and a central axis 1 which penetrates the center of the seeding device housing 5 and slides through the side plates 6 at both ends thereof. The two ends of the seeding device housing 5 are rotatably supported on the seed box housing 4 through a first supporting assembly, and the two ends of the central axis 1 are rotatably supported in the first supporting assembly through a second supporting assembly. A plurality of drum-type seeding devices 17 arranged in a circle around the central axis 1 are arranged in the seeding device housing 5. A plurality of longitudinal seeding grooves of different types arranged alternately are arranged on the outer circumferential surface of the seeding device 17. Each seeding device 17 is rotatably mounted on the side plate 6 through a rotating shaft 16. When the seeding device housing 5 rotates, the seeding device 17 can be driven to revolve around the central axis 1 to achieve a fixed type of seeding groove; the central axis 1 and each rotating shaft 16 are connected by a gear transmission assembly similar to a planetary gear mechanism. When the central axis 1 rotates, the gear transmission assembly can drive each seeding device 17 to rotate to achieve a type switching of the seeding groove to adapt to seeding of different crops. The present invention adopts a gear transmission assembly similar to a planetary gear mechanism. When different types of seeding slots are required, the gear transmission assembly connecting the central axis 1 and each rotating shaft 16 can drive the seeding device to rotate, so as to switch the types of seeding slots on the seeding device, thereby realizing the switching of different types of seeding slots without disassembling the seeding device, realizing the seeding operation of different crops, and meeting the actual demand of "one machine for multiple uses" of the seedling raising line. In addition, there is no need to disassemble and assemble different seeding slots during the switching process, which can reduce labor costs, improve adjustment efficiency, and realize unmanned operation.

[0022] In this embodiment, the gear transmission assembly is located in the seed meter housing 5, including a sun gear 12 installed on the central shaft 1 and a planetary gear 15 installed on each rotating shaft 16 and located between the seed meter 17 and the side plate 6. The planetary gears 15 are meshed with the sun gear 12 for transmission. A sun gear driving sprocket 2 is installed at one end of the central shaft 1. When the sun gear driving sprocket 2 rotates, the sun gear 12 rotates with the central shaft 1, so that each planetary gear 15 drives the coaxial seed meter 17 to rotate.

[0023] In this embodiment, the side plate 6 and the seed box housing 4 are respectively provided with a first through hole and a second through hole for passing the central axis 1. The first supporting assembly includes a sun gear bearing seat 9 rigidly connected to the first through hole on the side plate 6, an intermediate bearing 10 installed on the outer periphery of the sun gear bearing seat 9, and an intermediate bearing seat 11 rigidly connected to the second through hole on the seed box housing 4. The sun gear bearing seat 9 passes through the intermediate bearing seat 11 and is rotatably supported in the intermediate bearing seat 11 through the intermediate bearing 10. The outer end of the sun gear bearing seat 9 is fixedly provided with a seed meter housing driving sprocket 3. When the seed meter housing driving sprocket 3 rotates, the sun gear bearing seat 9 drives the seed meter housing 5 to rotate so that the seed meter 17 revolves. During the revolution, the rotation speeds of the sun gear driving sprocket 2 and the seed meter housing driving sprocket 3 must be kept the same to prevent the sun gear 12 from driving the planetary gear 15 and the seed meter 17 to rotate, thereby ensuring that the type of the seeding slot remains unchanged. During rotation, the seed meter housing drives the sprocket 3 to stop rotating, and the sun gear drives the sprocket 2 to start rotating, driving the planetary gear 15 to rotate, and then drives the seed meter 17 installed on the same rotating shaft 16 to rotate, until the seeding groove on the seed meter 17 rotates to the required type, and the sun gear drives the sprocket 2 to stop rotating, thereby adapting to the seeding needs of different crops.

[0024] In this embodiment, the second supporting assembly includes sun gear bearings 8 provided at both ends of the central shaft 1. The two ends of the central shaft 1 are rotatably supported in the sun gear bearing seat 9 through the sun gear bearings 8. The ends of the central shaft 1 extend out of the sun gear bearing seat 9. The sun gear driving sprocket 2 is installed on the ends of the central shaft 1 and is located on the outside of the driving sprocket 3 of the seed meter housing.

[0025] In this embodiment, a plurality of third through holes for the rotation shafts 16 to pass through are further provided on the outer periphery of the seed metering device side plate 6, and each third through hole is rigidly connected to a planetary gear bearing seat 14, in which a planetary gear bearing 13 is installed, and both ends of each rotation shaft 16 are rotatably installed in the planetary gear bearing seat 14 through the planetary gear bearing 13.

[0026] In this embodiment, two groups of gear transmission components are provided, which are symmetrically arranged at two ends of the seed meter housing 5 to make the transmission more stable.

[0027] In this embodiment, the seeding groove is a groove provided on the outer peripheral surface of the seeding device 17 and longitudinally passing through both ends, and the shape of the groove preferably includes U-shape, V-shape, semicircle and dovetail shape, and the types of seeding grooves include two, three or four different shapes of grooves, and grooves of different shapes are arranged alternately. The more types of seeding grooves there are, the more different crops can be applied, and the wider the application range.

[0028] In this embodiment, longitudinal seeding holes corresponding to the number of seeding devices 17 are provided on the seeding device housing 5, and each longitudinal seeding hole is connected to the seeding slot on the corresponding seeding device 17. The length of the longitudinal seeding hole corresponds to the length of the seeding slot. When seeding, the seeding device housing 5 revolves around the central axis 1 with the seeding device 17, and the seeding device 17 does not rotate. At this time, the seeds in the seed box fall into the seeding slot connected to it through the longitudinal seeding holes on the seeding device housing 5. After rotating to the bottom, the seeds in the seeding slot pass through the longitudinal seeding holes and fall. When it is necessary to switch the seeding slot, the seeding device 1 rotates 7 times, stops rotating after the required seeding slot is connected to the longitudinal seeding holes, and then revolves to realize seeding.

[0029] In this embodiment, the seed meter housing driving sprocket 3 , the sun gear driving sprocket 2 , and the ends of the sun gear 12 and the planetary gear 15 are all positioned by means of the elastic retaining ring 7 .

[0030] Working principle: When the seedling raising line operates normally, the rotation speeds of the sun gear driving sprocket 2 and the seed meter housing driving sprocket 3 remain the same to prevent the sun gear 12 from driving the planetary gear 15 and the seed meter 17 to rotate, thereby ensuring that the type of seeding slot on the seed meter 17 does not change.

[0031] When it is necessary to adjust the type of seeding slot on the seeding device 17, the seeding device housing drives the sprocket 3 to stop rotating, and the sun gear drives the sprocket 2 to start rotating, driving the planetary gear 15 to rotate, and then drives the seeding device 17 installed on the same rotating shaft 16 to rotate, until the seeding slot on the seeding device 17 is rotated to the required type, and the sun gear drives the sprocket 2 to stop rotating, thereby adapting to the seeding needs of different crops.

[0032] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
