[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-4 In this embodiment of the utility model, a seedling cultivation device for corn breeding and cultivation includes two symmetrically arranged frame bodies 1. Each frame body 1 has a sprocket set 2 installed on its inner side. A toothed chain 3 is connected to the sprocket set 2, and multiple seedling trays 4 are provided between the two toothed chains 3.

[0029] The frame body 1 includes a main frame body 11, and a front side frame 12 is welded to one side of the main frame body 11;

[0030] The sprocket assembly 2 includes a first sprocket 21 and a second sprocket 22; both the first sprocket 21 and the second sprocket 22 are mounted on the front frame 12. The first sprocket 21 is located above the second sprocket 22, and the center distance between the first sprocket 21 and the second sprocket 22 is not less than the width of the seedling tray 4.

[0031] The inner side of the toothed chain 3 is riveted with a C-shaped buckle, which is rotatably connected to the convex shafts at both ends of the seedling tray 4; this ensures that the seedling tray 4 maintains a stable horizontal position during circulation, which is the same principle as the placement plate in the above patent, and therefore will not be described in detail.

[0032] By adopting the above technical solution, during seedling cultivation, the seedlings are planted in seedling trays 4. The cooperation of the sprocket assembly 2 and the toothed chain 3 can drive multiple seedling trays 4 to circulate. During the circulation process, since the first sprocket 21 is located above the second sprocket 22, and the distance between the axes of the first sprocket 21 and the second sprocket 22 is not less than the width of the seedling tray 4, the two seedling trays 4 that circulate to this point are staggered, which allows the seedling tray 4 below to be fully displayed in front of the seedling growers, greatly facilitating the removal of weeds and diseased seedlings.

[0033] Furthermore, the height of position 4 of the seedling tray is suitable when the cycle is completed, so there is no need to raise the tray for operation. The seedling operator can sit on one side of the equipment to remove the seedlings.

[0034] In this embodiment, the sprocket assembly 2 further includes a third sprocket 23, a fourth sprocket 24, and a fifth sprocket 25; the third sprocket 23 is disposed on the top of the main frame 11; the fifth sprocket 25 is symmetrically disposed on the main frame 11 with the first sprocket 21; and the fourth sprocket 24 is disposed above the fifth sprocket 25.

[0035] By adopting the above technical solution, there is a certain angle between the third sprocket 23 and the fourth sprocket 24. This design enables the seedling tray 4 to achieve the effect of watering or uniform irrigation of water and fertilizer during the circulation process.

[0036] In this embodiment, the first sprocket 21, the second sprocket 22, the third sprocket 23, the fourth sprocket 24 and the fifth sprocket 25 are all connected to the frame body 1 through bearing seats, and a speed reducer 7 is also installed on the outside of the first sprocket 21.

[0037] The reducer unit 7 is used as a drive source. Both reducer units 7 use Dow reducers. In order to ensure the synchronous operation of the two reducer units 7, we adopt a master-slave control mode. One reducer unit acts as the master controller, directly receiving external commands (such as speed and position); the other acts as the slave controller, receiving the real-time status of the master controller through a communication interface (such as CAN or Ethernet) and adjusting according to the output of the master controller.

[0038] The controller for controlling the synchronous operation of the two reducer units 7 can be either Siemens S7-1200 / 1500 or Mitsubishi FX5U.

[0039] It should be noted that the master-slave control mode of the speed reducer unit is existing technology, and its specific working principle will not be elaborated here.

[0040] In this embodiment, a spray assembly 6 is installed on the upper end and top of one side of the main frame 11; the nozzles of the two spray assemblies 6 are both facing the seedling tray 4.

[0041] More specifically, the spray assembly 6 includes a fixing rod 61 fixed to two frame bodies 1. Multiple snap-fit ​​pieces 62 are fixed on the frame bodies 1, and water drains 63 are snap-fitted onto the multiple snap-fit ​​pieces 62. Multiple atomizing nozzles 64 are evenly distributed on the water drains 63. One end of each of the two water drains 63 is connected to a three-way connector 66 through a water distribution pipe 65. The three-way connector 66 is also connected to a water pump or a water-fertilizer integrated machine through a water pipe.

[0042] By adopting the above technical solution, when watering or fertilization is required, an external water pump or fertilizer will deliver water and fertilizer to the three-way connector 66. After being diverted by the water distribution pipe 65, the water will enter the two water outlets 63, and then be sprayed onto the seedlings through the atomizing nozzles 64, thereby achieving watering or fertilization of the seedlings.

[0043] It should be noted that the water pump or fertigation machine is an independent system, and the amount of water or fertilizer is controlled by the seedling nursery staff according to the actual condition of the seedlings.

[0044] The working principle of this invention is as follows: During seedling cultivation, seedlings are planted in seedling trays 4. The cooperation of the sprocket assembly 2 and the toothed chain 3 can drive multiple seedling trays 4 to circulate. During the circulation process, since the first sprocket 21 is located above the second sprocket 22, and the distance between the axes of the first sprocket 21 and the second sprocket 22 is not less than the width of the seedling tray 4, the two seedling trays 4 that circulate to this point are staggered, allowing the lower seedling tray 4 to be fully displayed in front of the seedling growers, greatly facilitating the removal of weeds and diseased seedlings.

[0045] Furthermore, the height of position 4 of the seedling tray is suitable when the cycle is completed, so there is no need to raise the tray for operation. The seedling operator can sit on one side of the equipment to remove the seedlings.

[0046] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0047] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style of the specification is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
