Technical Field

[0001] The utility model relates to the technical field of seedling cultivation, in particular to a seedling cultivation device with an automatic fertilization function. Background Art

[0002] Seedling cultivation refers to the cultivation of seedlings in a nursery, hotbed or greenhouse in preparation for transplanting into the land for planting. Currently, seedling cultivation is generally carried out in a greenhouse. During the seedling cultivation process, the seedlings need to be fertilized in time according to their development and growth needs to ensure their normal development.

[0003] Traditional seedling fertilization is generally done manually, but this method is inefficient and consumes a lot of labor. With the development of technology, current greenhouses are generally equipped with automatic fertilization devices. In order to save greenhouse space, a hanging structure is generally used to fertilize the seedlings by drip irrigation. However, the hanging structure will increase the load-bearing burden of the greenhouse and is inconvenient for inspection and maintenance.

[0004] Therefore, the utility model proposes a seedling raising device with automatic fertilization function to improve the above-mentioned problem. Utility Model Content

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the implementation regulations described are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of 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.

[0020] Example

[0021] See also Figure 1-4 , as shown in the figure: This embodiment is a preferred implementation of the technical solution, a seedling raising device with automatic fertilization function, comprising a conveying device 2 overlapped end to end, a seedling raising tray 1 arranged on the conveying device 2 and a fertilizer nozzle 3 fixed to the edge of the conveying device 2; the conveying device 2 comprises a side plate 21, a bracket 22 fixed to the upper edge of the outer side of the side plate 21, a pressing plate 23 fixed to the inner side of the bracket 22, and a conveyor belt 26 movably arranged between the side plates 21; the seedling raising tray 1 is arranged on the upper side of the conveyor belt 26, the fertilizer nozzle 3 is fixed to the outer side of the bracket 22, the spraying end of the fertilizer nozzle 3 is located above the seedling raising tray 1, and the lower edge of the pressing plate 23 is in contact with the upper side of the conveyor belt 26;

[0022] It should be noted that: in the seedling raising device involved in the present application, the conveying device 2 is used to replace the traditional fixed supporting structure, so that the seedling raising tray 1 used for seedling cultivation can move along the direction of the conveyor belt 26, and cooperate with the automatic fertilization of the fertilization nozzle 3 to replace manual fertilization, thereby improving efficiency. At the same time, compared with the current suspended automatic fertilization structure, it can reduce the load-bearing burden on the top of the greenhouse. Therefore, the automatic fertilization seedling raising device has high operating stability and great practical value. In specific use, the seedling raising tray 1 is placed on the conveyor belt 26 at intervals, and the conveying device 2 is controlled to start regularly. After the conveying device 2 is started, several of the seedling raising trays 1 move in a circular motion along a fixed direction. During the movement, each time it passes the fertilization nozzle 3, under the action of the external sensing element, the fertilization nozzle 3 automatically fertilizes the seedlings built in the seedling raising tray 1, which is efficient and fast. The conveying device 2 replaces the traditional fixed structure, which is also convenient for the subsequent taking and placing of the seedling raising tray 1.

[0023] Among them Figure 1 and Figure 2 As shown, the conveying device 2 is connected to the external control end of the fertilizer nozzle 3, and a plurality of the fertilizer nozzles 3 are correspondingly connected to different fertilizer pipes;

[0024] It should be noted that: the conveying device 2 and the fertilizer nozzle 3 both operate automatically under the action of the external control end. First, the seedlings in the seedling tray 1 are automatically fertilized. The operating intervals of the conveying device 2 and the fertilizer nozzle 3 are carried out according to a predetermined program. Several fertilizer nozzles 3 are set up for the injection of different types of liquid fertilizers.

[0025] Among them Figure 3 As shown, a driving roller 29 is arranged in the middle of the side plate 21, and a motor 24 is fixed to the end of the driving roller 29, and the motor 24 is fixed to the middle of the outer side of the side plate 21, and the driving roller 29 is connected to the conveyor belt 26; a transmission roller 27 is arranged at the end of the side plate 21, and the transmission roller 27 is connected to a limiting roller 28 via a belt, and the limiting roller 28 is fixed below the end of the side plate 21, and the transmission roller 27 and the limiting roller 28 are both connected to the conveyor belt 26; an adjusting roller 25 is arranged at the edge of the side plate 21, and the adjusting roller 25 is connected to the conveyor belt 26;

[0026] It should be noted that when the conveying device 2 is in use, the motor 24 drives the driving roller 29 to rotate. Under the action of the driving roller 29, the conveyor belt 26 is transmitted along a fixed track. During this process, the transmission roller 27 is used to assist the conveying movement of the conveyor belt 26, the limiting roller 28 is used to assist the conveyor belt 26 to maintain a fixed track, and the adjusting roller 25 is used to adjust the tightness of the conveyor belt 26.

[0027] Among them Figure 4 As shown, arc-shaped adapter plates are fixed to the ends of the side plates 21 in the adjacent conveying devices 2, and the four conveying devices 2 are at the same height;

[0028] It should be noted that: the arc-shaped transfer plate is used to receive the seedling tray 1 on the conveyor belt 26, and as a transfer structure, the seedling tray 1 on one of the conveying devices 2 is transferred to the conveying device 2 adjacent thereto. In actual operation, the conveyor belt 26 drives the seedling tray 1 to move. When the seedling tray 1 reaches the arc-shaped transfer plate, due to inertia, it moves along the arc-shaped transfer plate until it reaches the next conveyor belt 26. Since the arc-shaped transfer plate is not a necessary technical feature of the present application and the structure is relatively common, the present application does not make a restrictive description of it.
