Several spray heads are mounted on the lower surface of the water distribution tray. Several sliding rails are fixed to the inner wall of the housing. A return hood is mounted on the upper surface of the frame, located below the seedling trays and connected to the water tank. However, this device has a fixed spacing between the multiple seedling trays inside the housing, which cannot be adjusted according to the seedling height. Summary of the Invention

[0003] This utility model addresses the aforementioned shortcomings of the existing technology by providing a rice seedling transfer device that allows for individual adjustment of the height of the corresponding support frame based on the height of the rice seedlings in the seedling tray, thereby preventing the rice seedlings from being squeezed during transfer.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] A rice seedling transfer device includes a rectangular base plate, a U-shaped handle, a U-shaped mounting plate, casters, a seedling tray, an L-shaped support plate, an I-beam connecting plate, a strip connecting plate, a rectangular support plate, a limiting slide bar, and a rotating gear plate. The lower part of the U-shaped handle is connected to the rectangular base plate, and the lower part of the rectangular base plate is connected to the casters. Four casters are distributed at the four corners of the lower part of the rectangular base plate. The lower part of the U-shaped mounting plate is connected to the rectangular base plate. A set of U-shaped mounting plates is partially distributed on the rectangular base plate. The U-shaped mounting plates have strip-shaped sliding holes. The side of the L-shaped support plate fits against the U-shaped mounting plate. The side of the L-shaped support plate has a support plate side sliding post. The support plate side sliding post is adapted to the strip-shaped sliding hole and slides up and down in the strip-shaped sliding hole. The I-beam connecting plate connects the L-shaped support plate. Two sets of L-shaped support plates are symmetrically arranged on both sides of the I-beam connecting plate.

[0006] The lower surface of the seedling tray is attached to the L-shaped support plate, the side of the strip connecting plate is connected to the side sliding column of the support plate, multiple seedling trays are distributed above the rectangular base plate, the U-shaped fixing plate is connected to the strip connecting plate, the strip connecting plate is attached to the U-shaped mounting plate, the circular connecting plate is inserted into the U-shaped fixing plate, the side of the positioning connecting column has a positioning connecting column, the positioning connecting column passes through the U-shaped fixing plate, and the positioning connecting column rotates within the U-shaped fixing plate.

[0007] The positioning connecting column is connected to a rotating gear plate on its side. The rotating gear plate is in contact with the U-shaped fixing plate on its side. The rotating gear plate has a rocker arm on its side. The U-shaped mounting plate has a mounting plate side tooth plate on its side. The rotating gear plate meshes with the mounting plate side tooth plate. A rectangular support plate is connected to a strip connecting plate. A set of rectangular support plates are distributed on the side of the strip connecting plate. Beneficial effects

[0008] 1. This utility model features a rectangular base plate with four casters for easy movement and seedling transport. A set of U-shaped mounting plates is fixed on top of the rectangular base plate to support the seedling holding structure. The two ends of the I-beam connecting plate are connected to symmetrical L-shaped support plates, forming a support frame that supports the seedling trays. The side sliding posts of the support plates are inserted into the strip-shaped sliding holes. The connection between the four side sliding posts and the four strip-shaped sliding holes limits the position of the support frame, ensuring its horizontal and front-back position on the device. This allows the support frame to slide only up and down, making the spacing between the multiple seedling trays distributed vertically adjustable. The side sliding posts of the support plates are connected to the strip-shaped connecting plates, ensuring the entire support frame remains horizontal during vertical sliding.

[0009] 2. In this utility model, a U-shaped fixing plate is installed and fixed on the side of a strip connecting plate. A positioning connecting post passes through the U-shaped fixing plate and connects to a rotating toothed disc, so that the side of the rotating toothed disc fits against the U-shaped fixing plate. This prevents the connection between the two from breaking during the transfer of rice seedlings. The side of the rotating toothed disc meshes with the toothed plate on the side of the mounting plate. When the hand crank is turned, the rotating toothed disc rotates, causing the rotating toothed disc to move the support frame upward, thereby adjusting the height of the seedling tray in the device. A limiting slide rod is inserted into a rectangular support plate. A set of rectangular support plates supports the limiting slide rod and limits its position. A spring, supported by the rectangular support plate, applies a thrust to the slide rod's convex ring, causing the limiting slide rod to insert into the teeth on the outer side of the rotating toothed disc to axially position the rotating toothed disc, thereby fixing the height of the support frame. When using this device, the height of the corresponding support frame can be adjusted individually according to the height of the rice seedlings in the seedling tray, preventing the rice from being squeezed during the transfer of rice seedlings.

The lower part of the U-shaped mounting plate 03 is connected to the rectangular base plate 01, and a set of U-shaped mounting plates 03 is distributed on the upper part of the rectangular base plate 01, providing support for the seedling holding structure. The U-shaped mounting plate 03 has strip-shaped sliding holes 18. The L-shaped support plate... The side of L-shaped tray 07 fits into the U-shaped mounting plate 03. The side of L-shaped tray 07 has tray side sliding posts 09, which are adapted to strip-shaped sliding holes 18. The tray side sliding posts 09 are inserted into the strip-shaped sliding holes 18 and slide up and down within the strip-shaped sliding holes 18. The four tray side sliding posts 09 and the four strip-shaped sliding holes 18 are connected to limit the position of the entire support frame, ensuring the horizontal and front-back positions of the support frame on the device, so that the support frame can only slide up and down. The spacing between the multiple seedling trays 06 distributed vertically can be adjusted. I-beam connecting plate 08 connects the L-shaped tray 07. Two sets of L-shaped trays 07 are symmetrically arranged on both sides of I-beam connecting plate 08. The two ends of I-beam connecting plate 08 are connected to the symmetrical L-shaped trays 07, so that the symmetrical L-shaped trays 07 and I-beam connecting plate 08 form a support frame, which supports the seedling trays 06.

[0018] Example 2:

[0019] The lower surface of the seedling tray 06 of this utility model is in contact with the L-shaped support plate 07. The side of the strip connecting plate 10 is connected to the side sliding column 09 of the support plate. The connection between the strip connecting plate 10 and the side sliding column 09 of the support plate keeps the entire support frame horizontal when sliding up and down. Multiple seedling trays 06 are distributed above the rectangular base plate 01. The U-shaped fixing plate 17 is connected to the strip connecting plate 10. The U-shaped fixing plate 17 is installed and fixed on the side of the strip connecting plate 10. The strip connecting plate 10 is in contact with the U-shaped mounting plate 03.

[0020] Example 3:

[0021] The positioning connecting column 19 of this utility model is connected to the rotating toothed disk 16 on its side. The side of the rotating toothed disk 16 is in contact with the U-shaped fixing plate 17. The positioning connecting column 19 passes through the U-shaped fixing plate 17 and connects to the rotating toothed disk 16, so that the side of the rotating toothed disk 16 is in contact with the U-shaped fixing plate 17. This prevents the connection between the two from breaking during the transfer of rice seedlings. The side of the rotating toothed disk 16 has a rocker arm 15, and the side of the U-shaped mounting plate 03 has a mounting plate side toothed plate 04. The rotating toothed disk 16 meshes with the mounting plate side toothed plate 04. When the rocker arm 15 is held and rotated, the rotating toothed disk 16 rotates, causing the rotating toothed disk 16 to drive the support frame to move upward, thereby adjusting the height of the seedling tray 06 in the device. The rectangular support plate 11 is connected to the strip connecting plate 10, and a group of rectangular support plates 11 are distributed on the side of the strip connecting plate 10.
