DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

[0017] Embodiment: Please refer to Figure 1 , the present utility model provides a rice dry seedling raising device, including a main seedling raising pipe 1 and a plurality of dry land supporting assemblies 5. A branch seedling raising pipe 2 is fixedly communicated with the side wall of the main seedling raising pipe 1, a valve 3 is fixedly communicated with the end of the branch seedling raising pipe 2 far from the main seedling raising pipe 1, and the end of the valve 3 far from the branch seedling raising pipe 2 is fixedly communicated with a micro-spraying belt 4.

[0018] Please refer to Figure 2 and Figure 3, the dry land support assembly 5 includes a base 6. An externally threaded straight rod 7 is fixedly provided on the upper surface of the base 6. The externally threaded straight rod 7 is threadedly connected with an internally threaded sleeve 8. A rotating seat 9 is coaxially and fixedly provided at the top of the internally threaded sleeve 8. A rotating rod 10 is rotatably connected inside the rotating seat 9. A limiting block 12 that prevents the rotating rod 10 from moving upward is fixedly provided at the bottom of the rotating rod 10. A through hole 16 penetrating up and down is formed at the bottom of the rotating seat 9. A connecting rod 11 is integrally formed on the lower surface of the rotating rod 10. The bottom of the connecting rod 11 penetrates through the through hole 16 and is fixedly connected with the limiting block 12. The limiting block 12 is located inside the internally threaded sleeve 8. In the present utility model, by setting the outer diameter of the limiting block 12 to be larger than the diameter of the through hole 16, the limiting block 12 can prevent the rotating rod 10 from moving upward and prevent the rotating rod 10 from disengaging from the rotating seat 9 upward. A clamp 13 for clamping the micro-spraying belt 4 is fixedly connected to the top of the rotating rod 10. A sleeve 14 is fixedly provided on the upper surface of the base 6. A sleeve rod 15 that is longitudinally slidably sleeved with the sleeve 14 is fixedly provided at the bottom of the clamp.

[0019] On the basis of the above embodiment, in this embodiment, the externally threaded straight rod 7 and the internally threaded sleeve 8 are made of plastic material, and their structural performance can be maintained for a long time in the outdoor environment. A rotating handle 17 is fixedly provided on the outer wall of the internally threaded sleeve 8, and the rotating handle 17 facilitates the rotation of the internally threaded sleeve 8. In this embodiment, by rotating the rotating handle 17, the internally threaded sleeve 8 moves up and down along the externally threaded straight rod 7, which is convenient for adjusting the installation height of the rotating seat 9. Due to the rotational connection relationship between the rotating seat 9 and the rotating rod 10, while the rotating seat 9 rotates and moves up and down with the internally threaded sleeve 8, the clamp 13 can perform longitudinal lifting. Therefore, the installation height of the clamp 13 is adjustable, and multiple clamps 13 can realize the straight arrangement of the micro-spraying belt 4, avoiding the bending of the micro-spraying belt 4 due to uneven ground.

[0020] On the basis of the above embodiment, in this embodiment, self-lubricating and wear-resistant coatings are coated on both the inner surface of the sleeve 14 and the outer surface of the sleeve rod 15, which can significantly reduce the sliding wear between the sleeve 14 and the sleeve rod 15. There are two sleeves 14, and the two sleeves 14 are symmetrically arranged about the axis of the internally threaded sleeve 8. The horizontal cross-section of the sleeve rod 15 is rectangular. Therefore, the horizontal cross-section of the part of the sleeve 14 that slidably cooperates with the sleeve rod 15 is a hollow rectangle. The sleeve 14 and the sleeve rod 15 as a whole have good bending resistance and torsional resistance, and can stably support the clamp 13 while preventing the clamp 13 from rotating on the horizontal plane. The dry land support assembly 5 has good support reliability for the micro-spraying belt 4.

[0021] On the basis of the above embodiment, in this embodiment, a plurality of pointed anchor rods 18 are fixedly provided on the lower surface of the base 6, and the plurality of pointed anchor rods 18 are annularly and uniformly arranged about the longitudinal axis of the base 6. In this embodiment, the dry land support assembly 5 is stably installed by inserting the pointed anchor rods 18 into the ground.
