[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0029] Reference Figure 1-Figure 4 The utility model provides an embodiment: a spraying device for greenhouse seedling cultivation, comprising a water tank 1, a spraying assembly 2 and an installation assembly 4. A pump body 3 connecting the water tank 1 and the spraying assembly 2 is installed on the upper surface of the water tank 1. The spraying assembly 2 is fixed to the greenhouse seedling rack through the installation assembly 4. A water supply pipe 5 is fixed to the top of the side wall of the water tank 1, and the water supply pipe 5 is connected to the tap water pipe. A feeding port 6 for adding water-soluble fertilizer is opened on the top of the water tank 1. A mixing assembly is installed on the top wall of the water tank 1, and a PLC controller 11 is fixed to the outer wall of the water tank 1.
[0030] A solenoid valve 51 is fixed in the middle of the water supply pipe 5 , a liquid level sensor 10 is installed on the inner wall of the water storage tank 1 , and both the solenoid valve 51 and the liquid level sensor 10 are electrically connected to the PLC controller 11 .
[0031] In this embodiment, the PLC controller 11 utilizes a Siemens S7-300, and the liquid level sensor 10 utilizes an ELE-802 liquid level sensor. The liquid level sensor 10 monitors the water level inside the water tank 1 in real time and transmits a monitoring signal back to the PLC controller 11. When the water level falls below a lower limit, the PLC controller 11 controls the solenoid valve 51 to open, allowing water from the mains to flow through the water supply pipe 5 into the water tank 1, thus achieving automatic water replenishment.
[0032] The mixing assembly includes a motor 7 fixed to the upper surface of the water tank 1, a vertical shaft 8 is fixed to the bottom driving end of the motor 7, the bottom end of the vertical shaft 8 passes through the top wall of the water tank 1 and extends to the inside of the water tank 1, and a stirring blade 9 is fixedly connected to the bottom end of the vertical shaft 8.
[0033] After water-soluble fertilizer is added into the water storage tank 1 through the feeding port 6 , the motor 7 can be started to drive the stirring blade 9 to rotate, and the stirring blade 9 is used to fully mix the water and fertilizer.
[0034] The spray assembly 2 includes multiple circular tubes 21, and an atomizing nozzle 22 is installed on the side wall of each circular tube 21. A pipe sleeve 23 with a diameter larger than the circular tube 21 is fixed at one end. The end of the circular tube 21 away from the pipe sleeve 23 can be inserted into the pipe sleeve 23 at the end of the adjacent circular tube 21. The side wall of the pipe sleeve 23 is penetrated and threadedly connected with a first locking bolt 24. The water inlet and water outlet of the pump body 3 are respectively fixed with a water suction pipe 31 and a hose 32. The water suction pipe 31 is connected to the inside of the water tank 1, and the other end of the hose 32 is fixedly sleeved on the end of the circular tube 21 away from the pipe sleeve 23.
[0035] The outer wall of the pipe sleeve 23 is provided with threads, and an end cap 26 is provided to match the threads on the surface of the pipe sleeve 23.
[0036] By opening the pump body 3, the water in the water tank 1 can be pumped out, and then pumped into the circular tube 21 through the hose 32, and finally sprayed out from the atomizing nozzle 22 on each circular tube 21 to achieve spraying and fertilizing of the Polygonatum odoratum.
[0037] In this embodiment, the length of the spray assembly 2 can be spliced to suit practical needs. To do this, insert one circular tube 21 into the sleeve 23 of another circular tube 21 and tighten the first locking bolt 24 to secure the circular tube 21 within the sleeve 23. After the circular tubes 21 are spliced, insert the hose 32 onto the end without the sleeve 23. Finally, screw the end cap 26 onto the sleeve 23 away from the end of the hose 32 to seal the circular tubes 21.
[0038] A sealing ring 25 is provided on the inner wall of the pipe sleeve 23 .
[0039] When the pipe sleeve 23 and the round pipe 21 are connected, the sealing ring 25 can play a sealing role.
[0040] The mounting assembly 4 includes a U-shaped plate 41 , through one side of which a second locking bolt 43 is threadedly connected. A clamp 42 is fixed to the outer wall of the U-shaped plate 41 , and the clamp 42 can be fixedly sleeved on the surface of the round tube 21 .
[0041] After the spliced round tube 21 is inserted into the clamp 42, the U-shaped plate 41 can be fixed to the surface of the round tube 21 through the clamp 42. When installing the spray assembly 2, the U-shaped plate 41 can be clamped on the surface of the planting rack, and then the second locking bolt 43 can be tightened to fix the U-shaped plate 41.
[0042] Working Principle: When in use, first assemble the spray assembly 2 of appropriate length, then fix the spray assembly 2 to the planting frame and place it above the Yunnan Polygonatum planting pot through the installation assembly 4. During normal use, the water in the water tank 1 is pumped out by opening the pump body 3, and then sprayed out through the atomizing nozzle 22 of the spray assembly 2. When fertilization is required, water-soluble fertilizer is added to the water tank 1 through the feeding port 6, and then the motor 7 is started to drive the stirring blade 9 to rotate. The stirring blade 9 stirs and mixes the water and fertilizer, so that the water and fertilizer can be sprayed simultaneously.
[0043] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
