[0030] Reference Figure 1 As shown, the seedling tray soil lowering mechanism of the utility model is implemented as follows:

[0031] The seedling tray soil lowering mechanism comprises a box body 100 , a driving mechanism 200 , a stirring shaft 300 , a universal joint 400 , and a swing mechanism 500 .

[0032] The top of the box 100 is open to facilitate the placement of soil, and a soil hole 110 is provided at the bottom of the box 100 for discharging the scattered soil downward. In the drawings of this embodiment, in order to concisely show the specific structure of the box 100, the soil dividing structure is omitted, and the soil dividing structure disperses and fills the soil into each planting groove of the seedling tray from the bottom of the box 100.

[0033] The bracket 10 is connected to the outside of the box 100, and the driving mechanism 200 is installed on the bracket 10. The driving mechanism 200 is located above the box 100. The driving mechanism 200 is connected to one end of the universal joint 400, and the other end of the universal joint 400 is connected to the stirring shaft 300. The stirring shaft 300 extends into the interior of the box 100. The driving mechanism 200 drives the stirring shaft 300 to rotate inside the box 100 through the universal joint 400.

[0034] The swing mechanism 500 is connected to the bracket 10 , and the swing mechanism 500 is movably connected to the stirring shaft 300 . The swing mechanism 500 drives the stirring shaft 300 to swing.

[0035] The soil is put into the box body 100 from the top, and the driving mechanism 200 drives the stirring shaft 300 to rotate through the universal joint 400. The stirring shaft 300 stirs the soil in the box body 100, and drives the stirring shaft 300 to swing in the box body 100 through the swing mechanism 500, so as to change the position of the stirring shaft 300, expand the range of motion of the stirring shaft 300, prevent the soil in the box body 100 from piling up and agglomerating, and ensure that the soil output from the lower soil hole 110 is broken up and loose.

[0036] In some embodiments, a spiral blade 310 is installed on the outside of the stirring shaft 300 .

[0037] The spiral blades 310 outside the stirring shaft 300 help to break up and stir the soil inside the box 100, so that the soil inside the box 100 is driven by the spiral blades 310 and continuously surges up and down, thereby improving the effect of breaking up the soil.

[0038] In some embodiments, the rotation direction of the spiral blade 310 is the same as the rotation direction of the stirring shaft 300 .

[0039] When the stirring shaft 300 drives the spiral blade 310 to rotate, part of the loose soil is pushed upward along with the spiral blade 310, and the upper layer of unbroken soil sinks under the loose soil and contacts the spiral blade 310 to be broken up, which helps to improve the soil breaking effect.

[0040] In some embodiments, the outer diameter of the spiral blade 310 gradually increases from bottom to top.

[0041] Since the torque required to break up the soil is relatively low, in order to reduce the load on the universal joint 400, the drive mechanism 200, and the swing mechanism 500, the smaller the outer diameter of the spiral blade 310, the lighter the weight, and the end of the stirring shaft 300 away from the universal joint 400 is subjected to less force, which helps to reduce the power required to drive the stirring shaft 300, thereby reducing the load on the universal joint 400, the drive mechanism 200, and the swing mechanism 500.

[0042] In some embodiments, the stirring unit 20 is composed of a driving mechanism 200, a stirring shaft 300, a universal joint 400, and a swing mechanism 500. Two stirring units 20 are provided, and the two stirring units 20 are symmetrically arranged on the left and right sides of the box 100, and the swing trajectories of the two stirring shafts 300 are staggered with each other.

[0043] Two stirring units 20 are provided to stir and break up the soil inside the box 100 , thereby improving the soil breaking efficiency. The swinging tracks of the two stirring shafts 300 are staggered with each other, thereby preventing the two stirring shafts 300 from colliding with each other and being damaged.

[0044] In some embodiments, the driving mechanism 200 drives the stirring shaft 300 to rotate around the front-rear axis, and the two stirring shafts 300 are staggered front-to-back.

[0045] The two stirring shafts 300 are staggered along the front-rear direction of the box body 100 , and the two stirring shafts 300 are located on the left and right sides of the box body 100 , so that the ranges of the two stirring shafts 300 stirring and breaking up the soil are staggered, and the internal space of the box body 100 is fully utilized.

[0046] In some embodiments, the stirring shaft 300 oscillates up and down in a cycle.

[0047] In some embodiments, the seedling tray soil lowering mechanism further includes a seedling tray conveying mechanism 600 and a transmission mechanism 700 , and the seedling tray conveying mechanism 600 is connected to the driving mechanism 200 via the transmission mechanism 700 .

[0048] The seedling tray conveying mechanism 600, the transmission mechanism 700 and the driving mechanism 200 are linked to transmit the power of the seedling tray conveying mechanism 600 to the stirring shaft 300, ensuring that the stirring shaft 300 continues to rotate during the process of the seedling tray conveying mechanism 600 conveying the seedling tray.
