DETAILED DESCRIPTION

[0022] The utility model is further described below in conjunction with the accompanying drawings.

[0023] like Figure 1 , Figure 2 As shown, a combined seedling raising device for tobacco planting includes a seedling raising box 1, which has a concave cavity 2. A detachable partition plate 3 is provided on the seedling raising box 1, and the partition plate 3 divides the cavity 2 in the seedling raising box 1 into a lower filter layer 4 and an upper growing layer 5. The partition plate 3 has a plurality of seedling raising rooms 6 for raising seedlings. A bottom plate 7 corresponding to each seedling raising room 6 is provided in the lower filter layer 4. The four sides of each bottom plate 7 are in contact with the surrounding wall of the corresponding seedling raising room 6, and each of the bottom plates 7 can be raised and lowered relative to the seedling raising room 6. Each bottom plate 7 is provided with a plurality of filter holes 8.

[0024] In this embodiment, after the partition plate 3 is installed in the seedling box 1, the seedling box 1 is divided into a lower filter layer 4 and an upper growing layer 5. The upper growing layer 5 is used for planting tobacco seedlings, and the lower filter layer 4 is used for filtering water in the upper growing layer 5. Each seedling room 6 and the corresponding bottom plate 7 are combined to form a seedling space for planting tobacco seedlings. Due to environmental factors, different batches of tobacco seedlings may require soil layers of different depths for cultivation. The bottom plate 7 can be moved up and down to adjust the distance between it and the top of the partition plate 3 to adapt to different needs. At the same time, the partition plate 3 and the bottom plate 7 are detachable to facilitate the cleaning of the entire seedling box 1.

[0025] In this embodiment, a vertical groove 9 is provided on the peripheral wall of the seedling box 1 for inserting the end of the partition plate 3, and the vertical groove 9 extends vertically from the upper surface of the seedling box 1 to the inside of the seedling box 1. Preferably, the depth of the vertical groove 9 is half the height of the seedling box 1. By providing the vertical groove 9 to limit the insertion range of the partition plate 3, the structure is simple and the operation is convenient.

[0026] In this embodiment, a movable structure 10 for driving the bottom plate 7 to move up and down relative to the seedling chamber 6 is provided on the seedling box 1. The working part of the movable structure 10 is arranged at the center of the seedling box 1. The movable structure 10 includes a movable rod 11. The bottom of the movable rod 11 is connected to each bottom plate 7 through a connecting member 12. One end of the connecting member 12 is connected to the side surface of the movable rod 11, and the other end of the connecting member 12 is connected to the lower surface of the bottom plate 7. The upper end of the movable rod 11 is passed through the outside of the partition plate 3, and the top of the movable rod 11 is provided with a fixing member 13 for fixing the movable rod 11 after movement.

[0027] The movable structure 10 is used to move the base plate 7. After the partition plate 3 and the seedling box 1 are installed, the upper end of the movable rod 11 passes through the top of the partition plate 3. The operator can pull the upper end of the movable rod 11 to achieve the up and down movement of the base plate 7. When the base plate 7 is in a suitable position, the position of the movable rod 11 can be fixed by the fixing member 13, thereby achieving the fixation of the base plate 7.

[0028] In this embodiment, the axial cross section of each connecting member 12 is L-shaped. Providing the L-shaped connecting member 12 can increase the range of the bottom plate 7 moving up and down.

[0029] In this embodiment, the fixing member 13 can be a nut, and the outer surface of the end of the moving rod 11 outside the partition plate 3 has a thread that matches the nut. The fixing member 13 can rotate relative to the moving rod 11, so as to perform a linear motion along the length direction of the moving rod 11. At the same time, a through hole 14 is provided at the center of the partition plate 3 for the moving rod 11 to pass through. The diameter of the through hole 14 is larger than the diameter of the moving rod 11 and smaller than the diameter of the fixing member 13. When the moving rod 11 moves to a suitable position, the nut is rotated to a corresponding position. At this time, after the moving rod 11 is released, the nut directly abuts against the upper surface of the partition plate 3, which plays a role in limiting and fixing the moving rod 11.

[0030] Specifically, each bottom plate 7 is shaped like a trumpet and is concave downward. The filter holes 8 on each bottom plate 7 are evenly distributed on the bottom plate 7 at the convex part of the lower surface of the bottom plate 7 at the end of the connecting piece 12. The bottom plate 7 supports the soil layer for raising seedlings. The center of the bottom plate 7 is concave downward, which can lift the soil layer around the bottom plate 7 to gather toward the center of the bottom plate 7, and also facilitate the drainage of the soil layer.

[0031] In this embodiment, a fixed horizontal plate 15 is provided on the top of the seedling box 1 for fixing the partition plate 3 after being inserted into the vertical groove 9. One end of the fixed horizontal plate 15 can be rotatably connected to the seedling box 1, and the fixed horizontal plate 15 can abut against the upper surface of the partition plate 3 when rotating. The fixed horizontal plate 15 is connected to the seedling box 1 by rivets and can rotate 360 ​​degrees. When the partition plate 3 is installed in the vertical groove 9, the fixed horizontal plate 15 can be rotated to abut against the upper surface of the partition plate 3. At this time, the partition plate 3 cannot be pulled out of the vertical groove 9 upward.

[0032] The working principle of the utility model is as follows: first, insert the moving rod 11 into the through hole 14 of the partition plate 3, then connect the fixing piece 13 to the moving rod 11, and then insert the partition plate 3 into the seedling box 1 through the vertical groove 9 to keep the seedling box 1 and the partition plate 3 fixed by the fixing cross plate 15. At this time, the lower part of the moving rod 11 and the bottom plate 7 are located in the lower filter layer 4. The operator can pull the upper end of the moving rod 11 to realize the up and down movement of the bottom plate 7. When the bottom plate 7 is in a suitable position, the fixing piece 13 is used to fix the bottom plate 7. To fix the position of the moving rod 11, thereby fixing the bottom plate 7, each seedling room 6 and the corresponding bottom plate 7 are combined to form a seedling space for planting tobacco seedlings. When the tobacco seedlings are planted, the bottom of the soil layer is cone-shaped as a whole and gathers at the center of the bottom plate 7. At the same time, when there is more moisture in the soil layer, the moisture will enter the lower filter layer 4 through the filter holes 8 for storage. When transplanting the tobacco seedlings, the moving rod 11 can be pulled upward. At this time, the soil layer will move upward as a whole to expose the upper part of the soil layer from the seedling room 6, which is convenient for transplanting.

Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.

[0034] Although the terminology such as seedling raising box 1, cavity 2, partition plate 3, lower filter layer 4, upper raising layer 5, seedling raising chamber 6, bottom plate 7, filter hole 8, vertical slot 9, mobile structure 10, mobile rod 11, connecting member 12, fixing member 13, perforation 14, fixed horizontal plate 15 is used more frequently in this article, the possibility of using other terms is not excluded. The use of these terms is only for more convenient description and explanation of the essence of the utility model, and interpreting them as any additional restrictions is contrary to the spirit of the utility model.
