[0045] In this embodiment, the guide main frame 1 is arranged above the transmission belt. When the seedling blanket is transported by the transmission belt, the guide layer 2 on the guide main frame 1 separates the seedling blanket, allowing the seedlings to pass through the guide channel to prevent entanglement between the seedlings, and support the weak seedlings that lean to the left or right to enter the cutting range of the seedling claws, thereby reducing the direct breaking of the stems when the seedling claws cut and separate the seedlings.

[0046] In this embodiment, the widths of the diversion channels are set to be the same, which can ensure the density consistency of the seedlings during transplanting, thereby improving the survival rate and final yield of the seedlings.

[0047] In an optional embodiment, the guide layer 2 includes a guide frame and a guide plate 7; the guide frame is fixedly arranged on the guide main frame 1, and the guide plate 7 is fixedly arranged on the guide frame.

[0048] In this embodiment, the guide frame can be fixed on the guide main frame 1 by welding, bolt connection, riveting, etc., and then the guide plate 7 is fixed on the guide frame to form a stable guide layer 2 to ensure the guide and seedling supporting effects.

[0049] It is understandable that there are many ways to fix the guide frame on the guide main frame 1, which are not limited to the above-mentioned welding, riveting and bolting methods, and can also be clamping, etc., as long as the guide frame can be fixed on the guide main frame 1.

[0050] In an optional embodiment, the guide plate 7 and the guide frame are connected by welding, riveting, clamping or bolting.

[0051] In this embodiment, the welding method between the guide plate 7 and the guide frame can be spot welding or other welding methods, as long as the guide plate 7 can be fixed on the guide frame.

It can also be other fixed connection methods, such as binding, etc., as long as the guide plate 7 can be fixedly set on the guide frame.

[0053] In an optional embodiment, if Figure 5 As shown, the guide frame includes a first guide rod 5, a second guide rod 6 and a third guide rod 8; the first guide rod 5, the second guide rod 6 and the third guide rod 8 are connected in sequence to form an open frame structure; the guide plate 7 is fixedly arranged in the frame structure.

[0054] In this embodiment, the guide frame is divided into at least three parts, and an open frame structure is formed by the first guide rod 5, the second guide rod 6 and the third guide rod 8, and the guide plate 7 is fixed in the frame structure.

[0055] Such an arrangement can not only reduce the weight of the guide frame, but also facilitate the installation of the guide plate 7 and save materials.

[0056] In this embodiment, the first guide rod 5, the second guide rod 6 and the third guide rod 8 are integrally arranged, and are formed by bending a complete guide rod.

[0057] When in use, the first guide rod 5 or the third guide rod 8 is arranged at the entrance end of the seedling blanket, and the width of the rod structure is large, which can avoid scratching or cutting the seedlings in the seedling blanket, while achieving a better diversion effect.

[0058] It should be pointed out that the connection method of the first guide rod 5, the second guide rod 6 and the third guide rod 8 can be an integrated setting, or it can be other fixed connection methods, such as welding, bolt connection, etc., that is, as long as it can achieve the first guide rod 5, the second guide rod 6 and the third guide rod 8 fixedly connected to form a frame structure.

[0059] In an optional embodiment, the angle between the first guide rod 5 and the second guide rod 6 is an acute angle, which can form a tip when diverting.

[0065] In this embodiment, by setting the seedling supporting rod 4, the seedlings that tilt forward or backward in the traveling direction in the guide channel can be straightened by blocking. That is, the seedlings that tilt forward will be blocked by the seedling supporting rod 4 at the upper end during the transmission process by the transmission belt, thereby achieving the effect of passive straightening during the transmission of the lower end.

[0066] Specifically, in the present embodiment, the seedling supporting rod 4 is fixedly arranged at the end of the first guide rod 5 and is fixedly connected to the first guide rod 5 .

[0067] More specifically, the fixed connection method is welding.

[0076] A height adjustment groove is arranged on the lifting frame, and the opening direction of the height adjustment groove faces the direction in which the seedling blanket enters, that is, away from the direction in which the seedling blanket moves.

[0077] Specifically, in this embodiment, the opening direction of the height adjustment groove is obliquely upward.

[0078] Such an arrangement can keep the seedling supporting rod 4 in the height adjustment groove all the time through the force exerted by gravity and the seedling blanket, thereby improving the stability in use.

[0079] In this embodiment, the seedling supporting rod 4 is arranged in the height adjustment grooves at different heights, so that the height of the guide layer 2 can be adjusted.

[0080] In this embodiment, the lifting and positioning devices 3 are symmetrically arranged in pairs, respectively arranged at the two ends of the seedling supporting rod 4. When the height of the seedling supporting rod 4 is adjusted, the two ends of the seedling supporting rod 4 are moved at the same time, and the moving direction and distance are the same, thereby ensuring the stability of the adjusted guide layer 2.

[0081] In an optional embodiment, a stopper is provided at the end of the seedling supporting rod 4 to prevent the seedling supporting rod 4 from escaping from the height adjustment groove.

[0082] In this embodiment, after a stopper is set at the end of the seedling supporting rod 4, it can prevent the end of the seedling supporting rod 4 from moving inward due to vibration or the like, thereby preventing the end of the seedling supporting rod 4 from disengaging from the height adjustment groove, thereby ensuring the stability of the seedling supporting rod 4 in the height adjustment groove.

[0083] In this embodiment, the connection between the stopper and the seedling supporting rod 4 can be an integrated setting, or it can be welding, clamping, etc., as long as the stopper can be fixedly set at the end of the seedling supporting rod 4.
