[0041] 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 work are within the scope of protection of the present invention. The present invention is further described in conjunction with the drawings and embodiments:

[0042] Refer to the attached Figure 1 -Attached Figure 3 As shown, an agricultural greenhouse spraying device includes:

[0043] The fixing member 1 is arranged at the top of the greenhouse to play the role of installation and fixing. There are one or more sets of fixing members. During the implementation process, they are connected to the greenhouse frame.

[0044] The main liquid pipe 2 is connected to the fixing member 1 and is arranged horizontally along the inner length direction of the greenhouse and is located in the middle of the greenhouse. One end of the main liquid pipe 2 is open and the other end is closed. The length of the main liquid pipe 2 is determined according to the actual length of the greenhouse. This embodiment will not be described in detail.

[0045] The liquid injection assembly 3 is provided inside the greenhouse and is used to store and pump the liquid medicine. The liquid outlet end of the liquid injection assembly 3 is connected to the open end of the main liquid pipe 2. When the liquid injection assembly 3 is operated, the liquid medicine is pumped into the main liquid pipe 2.

[0046] There are several branch liquid pipes 4 and they are arranged vertically and linearly along the body of the main liquid pipe 2 to form several branches of the liquid medicine in the main liquid pipe 2;

[0047] The number of the mounting pipes 5 is the same as that of the branch pipes 4 and they are horizontally arranged on the branch pipes 4. The mounting pipes 5 are arranged horizontally along the width direction of the greenhouse. The length of the mounting pipes 5 is determined according to the actual width of the greenhouse. This embodiment will not be described in detail.

[0048] There are several connecting pipes 6 and they are arranged vertically and linearly along the body of the mounting pipe 5. In consideration of the spraying effect, in this embodiment, the connecting pipes 6 are hoses so that the connecting pipes 6 will shake during the spraying process, thereby making the spraying more uniform.

[0049] The number of the nozzles 7 is the same as that of the connecting pipes 6 and they are vertically arranged on the connecting pipes 6. Considering the spraying effect, in this embodiment, the nozzles 7 are rotating nozzles 7 so that the spraying area of the liquid medicine is wider during the spraying process.

[0050] During the implementation of this embodiment, several nozzles 7 are arranged along multiple coordinate points inside the greenhouse, so that during the spraying process of the medicine, the medicine is pumped into each nozzle 7 through the liquid injection component 3 and sprayed out. The sprayed medicine evenly covers the crops in the greenhouse, thereby improving the uniformity of the medicine spraying. Moreover, since the entire device does not have too many mechanical structures and mainly utilizes the layout and connection between pipes, its structure is simple and easy to maintain.

[0051] For the above embodiments, refer to the attached Figure 1 As shown, the liquid injection component 3 includes:

[0052] A liquid storage tank 31 is provided in the greenhouse and contains liquid medicine;

[0053] A liquid pump 32 is provided in the greenhouse for pumping the liquid medicine;

[0054] A liquid inlet pipe 33, one end of which is connected to the liquid outlet of the liquid storage tank 31, and the other end of which is connected to the liquid inlet of the liquid pump 32;

[0055] The liquid outlet pipe 34 has one end connected to the liquid outlet of the liquid pump 32 and the other end connected to the open end of the main liquid pipe 2 , so that the liquid pump 32 operates to pump the liquid in the liquid storage tank 31 into the main liquid pipe 2 through the liquid outlet pipe 34 .

[0056] Considering the effect of spraying, the spraying area and spraying intensity of the nozzle 7 will be affected by the installation height of the nozzle 7. Therefore, in other embodiments, the height of the fixing member 1 can be adjusted, thereby changing the height of the nozzle 7. For details, refer to the attached Figure 4 As shown, the fixing member 1 includes:

[0057] A fixing plate 11 is vertically arranged at the top of the interior of the greenhouse and is provided with a plurality of positioning holes 111;

[0058] The second fixing plate 12 is vertically arranged on the first fixing plate 11 and is provided with a plurality of second positioning holes 121 for use with the first positioning holes 111;

[0059] Bolt 13 is inserted into one of the second positioning holes 121 and the first positioning hole 111 to limit the position of the second fixing plate 12 on the first fixing plate 11;

[0060] In this embodiment, the length of the fixing member 1 is adaptively changed according to the actual crop planting area and density in the greenhouse, thereby changing the height of the nozzle 7, and ultimately making the spraying area and spraying intensity adapt to the spraying needs of the crops.

[0061] In addition, considering the planting density and area of crops in the greenhouse, when the planting density and area of crops are small, a large number of nozzles 7 are not needed, and conversely, a large number of nozzles 7 are needed; then, in order to make the number and position of the nozzles 7 adapt to the actual planting density and area of crops in the greenhouse, for this purpose, refer to the attached Figure 5 and attached Figure 6 As shown, the branch pipe 4 is connected to the main pipe 2 by a docking piece 8, so that the branch pipe 4 and the main pipe 2 are detachable, and when the branch pipe 4 is detached, it can be sealed by the docking piece 8; specifically, the docking piece 8 includes:

[0062] There are multiple external threaded pipe heads 81 that are linearly arranged along the body of the main liquid pipe 2 and are threadedly connected to the ends of the branch liquid pipes 4 (in this embodiment, the branch liquid pipes 4 are internally threaded);

[0063] The sealing cover 82 is connected to the external threaded pipe head 81 that is not connected to the branch liquid pipe 4 to seal the external threaded pipe head 81 at that location and prevent the liquid from being sprayed out through that location during the spraying process.

[0064] In this embodiment, the branch pipe 4 is installed at a suitable external threaded pipe head 81 according to the actual planting density and area of the crops in the greenhouse, and the external threaded pipe head 81 where the branch pipe 4 is not installed can be sealed by the sealing cover 82.

[0065] In addition, in order to further improve the variability of the position of the nozzle 7, the connecting pipe 6 and the mounting pipe 5 are also connected by a docking piece 8.

[0066] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention. The scope of protection claimed in the present invention is defined by the appended claims and their equivalents.
