Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-5 The utility model provides a technical solution of a seedling raising rack for cultivating seedlings of crops: it includes a vertical frame 1, a plurality of seedling raising mechanisms 2 are arranged inside the vertical frame 1, universal wheels 3 are arranged at the four corners of the bottom surface of the vertical frame 1, and the plurality of universal wheels 3 are all provided with wheel brakes, the front side surface of the vertical frame 1 is fixedly connected to the outer side surface of a controller 4, and the controller 4 is electrically connected to the plurality of seedling raising mechanisms 2 at the same time.

[0027] The bottom ends of the four electric push rods 22 are fixedly connected to the four corners of the upper surface of the placement tray 23, respectively. The input ends of the four electric push rods 22 are electrically connected to the output ends of the controller 4. The placement tray 23 is connected to the stand 1 by setting a fixed plate 21 and the electric push rods 22. In the process of using this device for seedling cultivation, the user can use the extension and retraction of the electric push rods 22 to adjust the spacing between adjacent placement trays 23 according to the height of different crop seedlings, thereby avoiding the spacing of the placement trays 23 from hindering the growth of the seedlings.

[0028] The upper surface of the placement tray 23 overlaps with the bottom surfaces of multiple planting trays 25 at the same time. Multiple planting grooves 216 are opened on the left and right sides of each planting tray 25. The opposite surfaces of two adjacent planting trays 25 overlap, and the bottom surface of each planting groove 216 is opened with multiple seepage holes that penetrate and connect with the bottom surface of the planting tray 25.

[0029] The front and rear side surfaces of the multiple planting trays 25 are overlapped with the opposite surfaces of the two limiting plates 24 respectively, and the bottom surfaces of the two limiting plates 24 are fixedly connected to the upper surface of the placement tray 23. The upper surface of the placement tray 23 is provided with a water collecting groove 215 corresponding to the multiple planting trays 25 above and below, and the bottom of the water collecting groove 215 is provided with a plurality of seepage grooves 214 that are connected to the bottom surface of the placement tray 23. When irrigation is performed during the seedling raising process, excess water in the planting groove 216 flows into the water collecting groove 215 through the seepage holes, and flows into the collection tray 26 through the seepage groove 214 opened at the bottom of the water collecting groove 215 for collection and storage.

[0030] A collecting tray 26 is correspondingly provided on the lower side of the multiple seepage grooves 214. The left and right ends of the collecting tray 26 are respectively slidably connected to the two slide rails 213. The upper ends of the two slide rails 213 are fixedly connected to the bottom surface of the placement tray 23. By providing the slide rail 213 at the bottom of the placement tray 23 and slidingly connecting the collecting tray 26 to the slide rail 213, it is convenient for the user to disassemble the collecting tray 26 and process the sewage collected therein.

[0031] The opposite ends of the two planting trays 25 at the left and right ends are overlapped with the upper ends of the two limit frames 210 respectively, and the two limit frames 210 are respectively sleeved in the two through grooves 29. The two through grooves 29 are both opened in the placement tray 23 and penetrate and connect the upper and lower surfaces of the placement tray 23.

The two threaded holes 218 are respectively opened at the bottom ends of the two fixed plates 211, and the upper ends of the two fixed plates 211 are fixedly connected to the bottom surface of the placement tray 23. The limit screws 212 are arranged to contact the limit frame 210, so that the position of the limit frame 210 is limited by the limit screws 212 to prevent the return spring 28 from pulling the limit frame 210 downward, so that the limit frame 210 is used to limit the left and right directions of multiple planting trays 25.

[0034] The operating steps of the utility model are:

[0035] When using the present device for seedling raising operations, the user can place the seedling raising base soil and seeds in the hole formed by two adjacent planting grooves 216. When irrigation is performed during the seedling raising process, excess water in the planting grooves 216 flows into the water collecting groove 215 through the seepage holes, and flows into the collecting tray 26 through the seepage grooves 214 opened at the bottom of the water collecting grooves 215 for collection and storage. When the seedling raising is completed and the seedlings need to be transplanted, the user can rotate the limit screws 212 to make the limit screws 212 on both sides move away from each other. When the limit screws 212 deviate from the bottom of the limit frame, the tension of the reset spring 28 pulls the limit frame 210 down so that the top of the limit frame 210 moves to the inside of the through groove 29. Then the user can gradually pull the planting tray 25 from both sides to translate so that the seedling raising base soil and the seedlings are separated from the planting grooves 216, and the seedlings and the seedling raising base soil are completely removed from the planting grooves 216.
