Description

Technical Field

[0001] This application relates to the field of cabbage seedling cultivation, and in particular to a multi-layer adjustable cabbage seedling tray rack. Background Technology

[0002] Plant seedling trays are special containers used for cultivating plant seedlings. Plant seedling tray racks are racks used to place plant seedling trays. In order to facilitate seedling management and improve space utilization, plant seedling trays are usually placed on seedling trays.

[0003] However, during the cultivation process, the seedlings on top can block the seedlings below, causing some seedlings to not receive enough sunlight. Therefore, a multi-layer adjustable seedling tray rack is needed. The angle of the seedling tray can be adjusted by adjusting the structure to avoid the phenomenon of some seedlings not receiving enough sunlight and uneven lighting, thus ensuring the success rate of seedling cultivation.

An adjusting component is fixedly connected to the top of the adjusting frame. A rotating connector is fixedly connected to the top of the adjusting frame. The placement frame is rotatably connected to the rotating connector. A threaded torsion bar is provided through the right side of the adjusting frame. The threaded torsion bar passes through the adjusting frame and is engaged with one of the adjusting rods. The threaded torsion bar is threadedly connected to the adjusting frame. A tray body is provided in the inner cavity of the placement frame, and the tray body is adapted to the placement frame.

[0006] By adopting the above technical solution, the plate is placed in the inner cavity of the placement frame, the torsion bar is rotated, and the rack drives the placement frame to rotate through the gear, thereby changing the angle of the placement frame. Then, the adjustment frame is moved to move the placement frame to the appropriate position. The threaded torsion bar is rotated to limit the adjustment frame, thus completing the angle adjustment of the placement frame. This avoids some cabbage seedlings not receiving enough sunlight and ensures the success rate of cabbage seedling cultivation.

[0007] Preferably, the bottom of the frame is fixedly connected to four symmetrical transfer wheels, which are omnidirectional wheels.

[0008] By adopting the above technical solution and setting up transfer wheels, when the frame is in use, it can be moved to a suitable position for seedling cultivation by pushing the frame, avoiding the need for users to move the frame and improving the turnover speed of the frame.

[0009] Preferably, the top of the placement frame has two symmetrical openings, and the back of the frame is fixedly connected to two symmetrical handles.

[0010] By adopting the above technical solution and setting the opening, after the cabbage seedlings inside the plate are cultivated, the plate can be removed from the inner cavity of the placement frame by inserting the user's hand into the opening, which avoids the user having to spend a lot of time removing the plate and improves the speed of plate removal.

[0011] Preferably, the adjustment assembly includes a fixed frame fixed to the top of the adjustment frame. A gear is rotatably connected to the inner cavity of the fixed frame. One end of the gear extends through the outside of the fixed frame and is fixedly connected to the placement frame. A rack is provided in the inner cavity of the fixed frame. The rack meshes with the gear. Limiting strips are fixedly connected to both sides of the rack. Limiting grooves are formed on both sides of the inner cavity of the fixed frame. The limiting strips are adapted to the limiting grooves. A threaded rod is rotatably connected to the inner cavity of the fixed frame. The threaded rod passes through the rack and is threadedly connected to the rack. The front side of the threaded rod extends through the outside of the fixed frame and is fixedly connected to a torsion bar.

[0012] Preferably, the center point of the gear coincides with the center point of rotation on the other side of the placement frame, and the front and back sides of the rack are respectively in contact with the front and back sides of the inner cavity of the fixing frame.

[0013] Preferably, the limiting strip is a rectangular strip, the torsion bar is cylindrical, and the surface of the torsion bar is provided with anti-slip texture.

[0014] Preferably, the cross-section of the adjusting rod is U-shaped, the adjusting frame is I-shaped, and the top of the adjusting frame does not fit against the bottom of the placement frame.

[0015] In summary, this application includes at least one of the following beneficial technical effects:

[0016] 1. This utility model involves placing the disc inside the placement frame, rotating the torsion bar to make the rack drive the placement frame to rotate through the gear, thereby changing the angle of the placement frame. Then, the adjustment frame is moved to move the placement frame to the appropriate position. Rotating the threaded torsion bar limits the adjustment frame, thus completing the angle adjustment of the placement frame. This prevents some cabbage seedlings from not receiving enough sunlight and ensures the success rate of cabbage seedling cultivation.

[0017] 2. By setting up transfer wheels, this utility model allows the frame to be moved to a suitable position for seedling cultivation by pushing the frame during use, avoiding the need for users to move the frame and improving the turnover speed of the frame.

[0018] 3. By designing an opening, this utility model allows the user to remove the cabbage seedlings from the inner cavity of the placement frame by inserting their hand into the opening after the seedlings have been cultivated inside the plate. This avoids the user having to spend a lot of time removing the plate and increases the speed of plate removal. Attached Figure Description
