[0001] The utility model relates to a flue-cured tobacco floating seedling raising pool tray assistant, belonging to the technical field of flue-cured tobacco seedling raising. Background Art

[0002] At present, in the field of flue-cured tobacco production and seedling raising, the main method of floating seedling raising in the seedling raising greenhouse is used for seedling raising. The floating seedling raising of flue-cured tobacco is a seedling raising method in which a floating seedling raising tray filled with flue-cured tobacco seedling raising matrix is ​​floated on the water surface, the seeds are sown in the matrix, the tobacco seedlings take root and grow in the seedling raising matrix, and can absorb water and nutrients from the matrix and the seedling raising pool. However, during the tobacco floating seedling raising process, when the floating seedling raising tray in the seedling raising pool is not full, the floating seedling raising tray will float around in the seedling raising pool and its position is not fixed, which is inconvenient for the staff to operate. In addition, the nutrient solution also needs to be evenly supplemented during the seedling raising process, but the current method of directly transporting the nutrient solution to the pool through a pipe has the problem of uneven supplementation and affects the growth of flue-cured tobacco. Utility Model Content

[0021] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation of the utility model is described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific implementation disclosed below.

[0022] See also Figure 1 and Figure 2 The present embodiment is a flue-cured tobacco floating seedling pool tray assistant, comprising an operating rod 1, a crossbeam 2, a movable frame and a comb-shaped rod 3. The front end of the operating rod 1 is connected to the middle of the crossbeam 2, and the movable frame is mounted at both ends of the crossbeam 2. The movable frame comprises a support rod 4 and a movable wheel 5. The support rod 4 is fixed to the end of the crossbeam 2, and the movable wheel 5 is mounted at the bottom of the support rod 4. The distance between the two movable frames is slightly larger than the width of the seedling pool, so that the two movable frames can span the seedling pool. The comb-shaped rod 3 is installed at intervals at the bottom of the crossbeam 2 along the length direction. The length of the comb-shaped rod 3 ensures that the bottom of the crossbeam 2 can contact the nutrient solution in the seedling pool when it spans the seedling pool. The crossbeam 2 and the comb-shaped rod 3 are both hollow and interconnected. An inlet 7 is provided on the crossbeam 2, and an outlet is provided at the bottom of the comb-shaped rod 3. When in use, the crossbeam 2 spans above the seedling pool through the mobile frame, the comb-shaped rod 3 contacts the nutrient solution in the seedling pool, and the floating seedling tray is placed in the seedling pool. The comb-shaped rod 3 can well limit the position of the floating seedling tray, preventing the floating seedling tray from floating freely in the seedling pool so as to increase the workload of the staff. In addition, nutrient solution or oxygen can be added to the seedling pool through the inlet 7.

[0023] In order to quickly and evenly replenish the nutrient solution, a liquid adding mechanism is also included, which includes a liquid adding barrel 8, a liquid adding pump 9 and a liquid adding tube 10. One end of the liquid adding tube 10 is connected to the liquid adding barrel 8 through the liquid adding pump 9, and the other end of the liquid adding tube 10 is connected to the inlet 7. The nutrient solution to be replenished is contained in the liquid adding barrel 8, so that the nutrient solution can be transported to the crossbeam 2 and the comb-shaped rod 3 through the liquid adding mechanism and discharged into the seedling pool, thereby achieving uniform and rapid replenishment of the nutrient solution, and the crossbeam 2 and the comb-shaped rod 3 can be moved during replenishment to achieve uniform mixing of the replenished nutrient solution with the original nutrient solution in the seedling pool.

[0024] During the floating seedling cultivation process, since the ventilation tissue inside the tobacco root system is underdeveloped and part of the root system grows in the nutrient solution for a long time, the pool surface is covered by the seedling tray, and the contact area between the liquid surface and the air is small, resulting in insufficient oxygen supply to the root system and inhibiting the differentiation of root cells. To solve this problem, an oxygenation mechanism is also included, which includes an oxygenator and an oxygen supply pipe. One end of the oxygen supply pipe is connected to the oxygenator, and the other end is connected to the inlet 7, so that oxygen can be supplemented to the seedling pool through the oxygenation mechanism, the crossbeam 2 and the comb-shaped rod 3 when needed to ensure the growth of the tobacco root system.

[0025] For the convenience of operation, a hollow vertical rod 6 is provided on the crossbeam 2, the interior of the vertical rod 6 is connected with the interior of the crossbeam, the inlet 7 is arranged at the top of the vertical rod 6, and the operating rod 1 is arranged on the side of the vertical rod 6, so that the liquid adding tube 10 or the oxygen supply tube connected to the inlet 7 can be led out in a standardized manner.

[0026] The above-mentioned embodiments only express several implementation methods of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the utility model, and these all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
