DETAILED DESCRIPTION
[0030] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.
[0031] like Figures 1-9 As shown, a transfer stand for transplanting seedlings provided by an embodiment of the present invention includes a movable seat 101, a frame 103 is provided on the upper surface of the movable seat 101, and a rotating shaft 104 is rotatably provided in the frame 103, a seedling support plate 105 is fixedly provided on the outer wall of the rotating shaft 104, an annular mounting opening 106 is provided on the outer side of the seedling support plate 105, and a fixed shaft 107 is fixedly connected to the mounting opening 106, a seedling support plate 108 is rotatably connected to the outer side of the fixed shaft 107, and a seedling support groove 109 is provided on the upper surface of the seedling support plate 108 for supporting the root position of the seedling, a universal wheel 102 is fixedly connected to the lower surface of the movable seat 101, and further includes:
[0032] An adjustment mechanism is provided below the seedling support plate 105 and is used to adjust the rotation amplitude of the seedling support plate 108;
[0033] The limiting mechanism is arranged outside the rotating shaft 104 and is used to limit the position of the seedlings so that the seedlings rotate together with the seedling tray 105;
[0034] A supporting mechanism is provided on the outside of the rotating shaft 104 and is used to support the seedlings;
[0035] The rotating mechanism is arranged above the frame 103 and is used to drive the rotating shaft 104 to rotate;
[0036] The traction mechanism is provided on an outer wall of one side of the frame 103 and is used to pull the movable seat 101 to move.
[0037] The seedling tray 105 can be adjusted to a horizontal state by the adjustment mechanism, and the seedlings to be transplanted can be placed on the seedling supporting plate 108, and the rotating mechanism can drive the rotating shaft 104 to rotate, and the rotating shaft 104 can drive the seedling supporting plate 105 to rotate, so that the seedling supporting plate 108 rotates together, and the limiting mechanism can rotate with the rotating shaft 104 to limit the position of the seedling stem, effectively preventing the seedlings from tipping over and falling from the seedling supporting plate 108. When the seedlings to be transplanted are all filled on the seedling supporting plate 105, the mobile seat 101 can be towed by the traction mechanism, and the seedlings can be supported by the supporting mechanism before traction, effectively avoiding To prevent the seedlings from tilting and causing the branches and leaves of the seedlings to be squeezed and damaged, when the movable seat 101 moves to the position to be transplanted, the seedling tray 105 can be rotated to make the seedlings rotate to just above the position to be transplanted. At this time, the limiting mechanism can automatically release the limitation on the position of the seedling trunk, and then the rotation amplitude of the seedling tray 105 can be adjusted by the adjusting mechanism so that the seedling tray 105 remains in a vertical state. At this time, the seedlings will automatically slide and fall to the position to be transplanted, and then the position of the movable seat 101 can be moved to transplant the next seedling, which effectively realizes the rapid transplanting of multiple batches of seedlings, saves time and effort, and has a better use effect.
[0038] As an embodiment of the present invention, the adjustment mechanism includes a tray 201, the upper surface of the movable seat 101 is fixedly provided with a support block 202, and the tray 201 is fixedly provided above the support block 202, the upper surface of the tray 201 is in contact with the lower surface of the seedling tray 105, the outer wall of the tray 201 is also provided with a seedling release port 203 connected to the installation port 106, the outer wall of the movable seat 101 is also inclined to provide a fixing hole, and a telescopic component 204 is fixedly provided in the fixing hole, the specific structure of the telescopic component 204 is not limited. In this embodiment, preferably, the telescopic component 204 adopts a hydraulic cylinder, and the telescopic end of the telescopic component 204 is fixedly provided with a push rod 205, which is located in the seedling release port 203, and the end of the push rod 205 is in contact with the lower surface of the seedling support plate 108. Before the seedling support plate 105 rotates, the push rod 205 can be driven to move by the telescopic component 204 so that the end of the push rod 205 is located at the seedling release port 20 3, when the seedling supporting plate 108 in the seedling supporting tray 105 rotates to the top of the seedling releasing opening 203, the seedling supporting plate 108 will be lifted by the push rod 205. When the seedlings need to be released, the push rod 205 can be retracted by the telescopic component 204 to release the lifting of the seedling supporting plate 108. At this time, the seedling supporting plate 108 will automatically swing down to make the seedlings slide to the position to be transplanted, which is very convenient to use. After the seedlings are transplanted, the movable seat 101 moves to the next transplanting position. At this time, the supporting rod 205 can be extended by the telescopic component 204, so that the supporting rod 205 can lift the seedling supporting plate 108 again until the seedling supporting plate 105 rotates and the seedling supporting plate 108 moves above the tray 201. At this time, the supporting rod 205 can be retracted to avoid the supporting rod 205 from hindering the rotation of the seedling supporting plate 105. When the next group of seedling supporting plates 105 moves to just above the seedling release port 203, the automatic transplanting operation of the seedlings can be repeated, and the use effect is better.

When the limiting plate 301 rotates together with the rotating shaft 104, the stem part of the seedlings will be restricted in the limiting opening 302 under the blocking action of the limiting hoop 303, effectively preventing the seedlings from falling during the transfer process with the moving seat 101. When the seedlings need to be transplanted, the stem part of the seedlings will rotate to the opening position, which will not affect the automatic falling of the seedlings, and the use effect is better.
[0040] As an embodiment of the present invention, the supporting mechanism includes a disc 401 that is sleeved on the outside of the rotating shaft 104.

The supporting frame 404 can play a role in supporting seedlings, effectively preventing the seedlings from tilting toward the middle position, resulting in the branches and leaves being squeezed, and the use effect is better.
[0041] As an embodiment of the present invention, the positioning assembly includes a positioning ring 406 that is sleeved on the outside of the rotating shaft 104. The outer wall of the rotating shaft 104 is provided with equidistantly distributed sockets 408. The outer wall of the positioning ring 406 is also provided with positioning holes that match the sockets 408. A pin 407 is inserted into the positioning hole, and the pin 407 passes through the socket 408. The upper surface of the positioning ring 406 is fixed with equidistantly distributed ring-shaped synchronization rods 409, and the synchronization rod 409 passes through the disc 401. The disc 401 can be supported by the positioning ring 406, and by inserting the pins 407 into different sockets 408, the positioning ring 406 can be adjusted to different heights, so that the height of the disc 401 can be appropriately adjusted according to the height of the seedlings. Under the action of the synchronization rod 409, the disc 401 can rotate together with the rotating shaft 104, so that the support frame 404 and the seedling support plate 108 are maintained on the same position line, which is more convenient for supporting seedlings and has a better use effect.
