Abstract
Description
Technical Field
[0001] This utility model relates to the field of tobacco seedling cultivation technology in tobacco seedling nursery ponds, specifically to a fertilizer and water circulation device for tobacco seedling nursery ponds. Background Technology
[0002] Currently, most tobacco seedlings are cultivated by placing floating trays in seedling ponds. The use of water-soluble fertilizer is an important part of the tobacco seedling cultivation process. In traditional floating seedling cultivation, the first step is to place an appropriate amount of water in the seedling pond and arrange the seedling trays floating in it. Then, according to the fertilizer requirements of the tobacco seedlings at different stages, fertilizer solution is prepared in a fertilizer tank outside the seedling pond. The prepared fertilizer solution is then poured into the seedling pond from the water inlet. During the entire seedling cultivation period, the water in the pond is drained after a period of use. During this period, the water in the pond is in a relatively stagnant state. Because some fertilizers have relatively poor water solubility, especially some powdery or coarse granular fertilizers, they sink to the bottom before dispersing and are difficult to disperse even with mechanical stirring. Since the seedling trays are floating in the seedling pond, it is not convenient to mechanically stir them. As a result, the fertilizer concentration at the water inlet of the seedling pond is much higher than that at the water outlet, leading to uneven distribution of fertilizer and pesticides throughout the seedling pond. There is a significant difference in the cultivation effect of tobacco seedlings at the water inlet and the water outlet of the seedling pond, which affects the overall tobacco seedling cultivation effect. Utility Model Content
[0003] The purpose of this invention is to provide a fertilizer and water circulation device for tobacco seedling nurseries, which solves the problem of uniform fertilizer and water concentration in the nursery, thereby ensuring the overall tobacco seedling cultivation effect.
[0004] To achieve the above objectives, the technical objectives of this utility model are achieved through the following technical solutions.
[0005] A fertilizer-water circulation device for a tobacco seedling nursery includes a fertilizer tank, a first water pump, and a first water pipe. Seedling trays are arranged floatingly in the tobacco seedling nursery. The front end of the first water pipe is connected to the fertilizer tank. The first water pump is located in the middle of the first water pipe. The rear end of the first water pipe is connected to the water inlet of the tobacco seedling nursery. The device also includes a second water pump and a second water pipe. The front end of the second water pipe is connected to the water outlet of the tobacco seedling nursery. The second water pump is located in the middle of the second water pipe. The rear end of the second water pipe is connected to the fertilizer tank.
[0006] The circulation device using the above technical solution can transform stagnant water in the seedling pond into flowing water using a first water pump and a second water pump, thereby ensuring uniform fertilizer water concentration in the seedling pond and guaranteeing the overall tobacco seedling cultivation effect.
[0007] Further defining the above technical solution, multiple agitators are provided in the fertilizer tank. Using agitators can, on the one hand, better dissolve the fertilizer in the water, and on the other hand, reduce the amount of undissolved fertilizer settling to the bottom.
[0008] Furthermore, the above technical solution further includes an intermittent cycle timer, which controls the start / stop of the second water pump's time interval. This intermittent cycle timer can be a time-controlled switch, such as a 220V aerator water pump fan motor automatic power-off timer. Its main function is to set a certain time interval in industrial automation to control the machine's start and stop. By adopting the above technical solution and using the intermittent cycle timer, the running time and interval of the circulating water can be adjusted, thereby achieving intelligent control operation and saving labor costs.
[0009] An inlet valve can also be installed at the water inlet of the tobacco seedling nursery, and the inlet valve is installed on the first water pipe, located behind the first water pump; a drain pipe is installed at the water outlet of the tobacco seedling nursery, and a drain valve is installed on the drain pipe, so as to better control the water inlet and outlet.
[0010] Furthermore, the first water pipe, the second water pipe, and the drain pipe are all made of PVC pipe. PVC pipes possess advantages such as acid and alkali resistance, corrosion resistance, good sealing, moisture resistance, and high tensile strength. Moreover, their smooth inner walls offer minimal resistance to flowing liquids, significantly improving water delivery efficiency. Attached Figure Description
[0011] Figure 1 This is a structural schematic diagram of an embodiment. Detailed Implementation
[0012] The present invention will be further described in detail below with reference to the accompanying drawings.
[0013] like Figure 1As shown, a fertilizer-water circulation device for a tobacco seedling nursery includes a fertilizer tank 3, a stirrer 31, a first water pump 1, a first water pipe 10, a second water pump 2, a second water pipe 20, an intermittent circulation timer 21, a drain pipe 40, an inlet valve 43, and a drain valve 44. Seedling trays 41 are arranged floatingly within the tobacco seedling nursery 4. The front end of the first water pipe 10 is connected to the fertilizer tank 3. The first water pump 1 is located in the middle of the first water pipe 10, and the rear end of the first water pipe 10 is connected to the water inlet of the tobacco seedling nursery 4. An inlet valve 43 is installed at the water inlet of the tobacco seedling nursery 4. On the first water pipe 10, located behind the first water pump 1, a drain pipe 40 is provided at the water outlet of the tobacco seedling nursery 4, and a drain valve 44 is provided on the drain pipe 40; the front end of the second water pipe 20 is connected to the water outlet of the tobacco seedling nursery 4, the second water pump 2 is located in the middle of the second water pipe 20, and the rear end of the second water pipe 20 is connected to the fertilizer tank 3; the intermittent cycle timer 21 controls the start / stop of the second water pump 2 at time intervals; multiple agitators 31 are provided in the fertilizer tank 3; the first water pipe 10, the second water pipe 20 and the drain pipe 40 are all made of PVC pipe.
[0014] The fertilizer water circulation device for tobacco seedling nursery using this technical solution, due to the installation of a second water pump and a first water pump, when the two water pumps are started, can circulate the fertilizer water in the nursery to ensure that the fertilizer water concentration at the inlet and outlet of the nursery is the same. On the other hand, it can also ensure that the fertilizer is further dispersed and dissolved to a greater extent. The purpose of setting and starting the agitator 31 in the fertilizer tank 3 is also to more fully disperse and dissolve the fertilizer. In addition, the intermittent cycle timer 21 is used to control the start / stop of the second water pump 2 at time intervals to form a pulse pattern. Multiple cycles of extraction can also better ensure the dissolution of fertilizer and a more uniform concentration of fertilizer water in the entire nursery.
[0015] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
