Description

Technical Field

[0001] The utility model relates to the technical field of seedling raising and fertilizing machines, in particular to a greenhouse seedling raising and fertilizing machine. Background Art

[0002] Greenhouse seedling cultivation refers to the cultivation of plant seedlings in a greenhouse environment. This cultivation method can artificially control the temperature, humidity, light and other conditions for plant growth, thereby achieving the best environment for plant growth, improving crop yield and quality, shortening the growth cycle, and even achieving off-season production. In my country, greenhouse seedling cultivation technology has been widely used in many fields such as vegetables, flowers, and fruits. Fertilization of seedlings is a key link because it directly affects the healthy growth of seedlings and the yield and quality of the final crop. In a greenhouse environment, due to artificial control of climatic conditions, seedlings tend to grow faster and have a more concentrated and sensitive demand for nutrients. Therefore, reasonable fertilization technology is particularly important. In the existing seedling fertilization, since the seedling tray is generally placed on a shelf in layers or laid flat on the ground, the stirred and mixed liquid fertilizer is placed in a spray pot. The spray pot has the advantage of controlled discharge and can evenly irrigate the liquid fertilizer into the seedling tray for fertilization. However, the disadvantages of using the spray pot are also obvious. The capacity is small, the spray pot is heavy, and the fertilizer is tiring to hold. Therefore, it is necessary to design a convenient greenhouse seedling fertilization machine. Utility Model Content

After adding the fertilizer and water into the mixing tank 1, flip the hopper cover 103 to cover the feed hopper 102, which can prevent debris from falling from the feed hopper 102 into the mixing tank 1. At this time, start the servo motor 3, the servo motor 3 drives the motor shaft 301 to rotate, and the motor shaft 301 drives the multiple stirring rods 302 to rotate inside the mixing tank 1, so as to stir and mix the fertilizer and water, thereby completing the dilution of the fertilizer concentration.

[0041] After the fertilizer and water are stirred and mixed in the mixing tank 1, the cart 2 is pushed to move the mixing tank 1 to the side of the seedling tray, and the fertilizer nozzle 403 is held and the liquid output of the fertilizer nozzle 403 is adjusted and controlled by the flow control valve 404. At this time, the liquid pump 4 is started to work, and the liquid fertilizer in the mixing tank 1 is extracted through the liquid extraction pipe 401, and discharged into the delivery hose 402 through the outlet of the liquid pump 4, and then discharged from the delivery hose 402 to the fertilizer nozzle 403, and then discharged into the seedling tray through the fertilizer nozzle 403 to fertilize the seedlings. The length of the delivery hose 402 is 3 meters, which can be easily pulled and manipulated to fertilize different positions in the seedling tray.
