Description

Technical Field

[0001] The utility model relates to the technical field of irrigation equipment, in particular to an irrigation device for planting dendrobium greenhouses. Background Art

[0002] Dendrobium is an orchid that prefers a semi-shady and humid environment. Its natural growth environment is usually epiphytic on tree trunks or rocks. When artificially cultivated, Dendrobium is generally cultivated in a greenhouse. The greenhouse can provide a controllable microclimate to protect Dendrobium from extreme weather, such as excessive sunlight, heavy rain, frost, etc. At the same time, the temperature, humidity and light in the greenhouse can be adjusted to create the most suitable conditions for the growth of Dendrobium.

[0003] In order to save space, plant as many Dendrobiums as possible in a limited space and achieve the maximum benefit from limited soil, three-dimensional planting is now mostly adopted, that is, Dendrobiums are planted on tree trunks or other pillars to achieve multi-layer cultivation. Although this can save land space, when spraying and irrigating Dendrobiums, it is generally done by arranging spray pipes on the top and installing nozzles on the pipes for spray irrigation. For Dendrobiums planted in a flat surface, this irrigation method can make Dendrobiums receive water evenly, but for Dendrobiums planted in a three-dimensional manner, Dendrobiums located in the lower layer may receive less water, resulting in uneven water received by Dendrobiums planted on the same trunk, affecting the consistency of Dendrobium growth. Utility Model Content

[0004] The embodiment of the utility model provides an irrigation device for growing dendrobium in greenhouse to solve the above-mentioned technical problems.

[0005] The embodiment of the utility model adopts the following technical scheme: it includes a spray unit and a connecting pipe fitting, the number of the spray units corresponds to the number of the Dendrobium planted trunks in the greenhouse, and two adjacent spray units are connected by a water pipe, the spray unit includes a plurality of water supply rings and a spray head arranged on the water supply ring, and the axes of the plurality of water supply rings coincide, the connecting pipe fitting is connected between two adjacent water supply rings above and below, and is used to transport water to the water supply rings from top to bottom. By arranging the spray unit on the periphery of the trunk where the Dendrobium is planted, and corresponding to each layer of Dendrobium planted on the trunk through the water supply ring, targeted spraying is performed, which can provide water to each layer of Dendrobium more accurately and evenly, helping to ensure that each layer of plants can get a relatively consistent water supply and reduce growth differences caused by uneven water.

[0006] Furthermore, the connecting pipe fitting includes a connecting piece and a connecting pipe threadedly connected to both ends of the connecting piece, the end of the connecting pipe away from the connecting piece is connected to the water supply ring, the connecting piece includes an internal hollow bridging pipe and a fixed pipe threadedly connected to both ends of the bridging pipe, the fixed pipe is threadedly connected to the connecting pipe, so as to facilitate the installation of the lower water supply ring.

[0007] Furthermore, the connecting pipe is provided with a transparent guide ring with a middle opening, and the diameter of the guide ring gradually increases from top to bottom, which can guide the water sprayed from the upper layer so that it will not fall onto the dendrobium in the lower layer, causing the dendrobium in the lower layer to receive too much moisture.

[0008] Furthermore, the water supply ring located at the top is a hard water supply ring, and the water supply ring located at the bottom layer is a flexible water supply ring, which can facilitate the installation of the lower layer water supply ring from the side around the trunk.

[0009] Furthermore, a valve is installed on the water delivery ring located at the top, which is convenient for controlling each spray unit, so that it can be targeted to choose whether to spray the dendrobium on the trunk.

[0010] Furthermore, it also includes a mounting frame, which is used to suspend the spray unit, and a mounting rod is provided on the uppermost water supply ring. The mounting frame and the mounting rod are detachably connected to facilitate the suspension and installation of the spray unit on the outside of the trunk of the Dendrobium planted in the greenhouse.

[0011] At least one of the above technical solutions adopted in the embodiment of the utility model can achieve the following beneficial effects:

[0012] In the utility model, a spray unit is arranged on the outer periphery of the trunk on which the Dendrobium is planted, and a plurality of water supply rings are provided to correspond one by one to each layer of the Dendrobium planted on the trunk, so that targeted spraying is performed on the multiple layers of the Dendrobium planted on the trunk, and water can be provided to each layer of the Dendrobium more accurately and evenly, which helps to ensure that each layer of the plants can obtain a relatively consistent water supply and reduce growth differences caused by uneven water.

[0022] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in combination with the specific embodiments of the utility model and the corresponding drawings. Obviously, the described embodiments 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.

[0023] The technical solutions provided by various embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0024] The utility model provides an irrigation device for planting dendrobium in greenhouse, comprising a spray unit and a connecting pipe 3. The number of the spray units corresponds to the number of dendrobium planting trunks in the greenhouse, and two adjacent spray units are connected through a water pipe 1. The spray unit comprises a plurality of water delivery rings 2 and a spray head 21 arranged on the water delivery ring 2. The number of the spray heads 21 is provided in plurality, and they are arranged equidistantly along the central axis of the water delivery ring 2, so that the dendrobium planted on the circumference of the trunk can receive the spray water, and the axis of the plurality of water delivery rings 2 coincides. A connecting pipe 3 is provided between two upper and lower adjacent water delivery rings 2. When irrigating, one of the water delivery rings 2 is connected to the water delivery ring 2. The water pipe 1 is connected to the water supply equipment to transport water. The water source enters each spray unit through the water pipe 1, and then is transported to each water supply ring 2 of each spray unit through the connecting pipe 3, and is sprayed out through the spray head 21 for spray irrigation. The length of the connecting pipe 3 corresponds to the spacing between two adjacent layers of Dendrobium planted above and below, so that each water supply ring 2 can correspond to each layer of Dendrobium. Preferably, the water supply ring 2 can be located above each layer of Dendrobium, and the spray head 21 is tilted downward to aim at the root of Dendrobium, so as to carry out targeted spray irrigation on Dendrobium, ensuring that each layer of plants can get a relatively consistent water supply.

[0025] Among them, Figure 4 as well as Figure 5 As shown, the connecting pipe 3 includes a connecting piece 31 and a connecting pipe 32 threadedly connected to both ends of the connecting piece 31, and the end of the connecting pipe 32 away from the connecting piece 31 is connected to the water supply ring 2. The connecting piece 31 includes an internally hollow bridging pipe 301 and a fixed pipe 302 threadedly connected to both ends of the bridging pipe 301, and the fixed pipe 302 is threadedly connected to the connecting pipe 32. When installing the lower water supply ring 2, first connect one of the fixed pipes 302 to the connecting ring fixedly connected to the water supply ring 2, and then connect the other fixed pipe 302 to the lower water supply ring 2. According to this method, the water supply ring 2 on each layer can be connected to the connecting pipe 3, so that the two adjacent water supply rings 2 are connected, and sealing rings (not shown in the figure) are installed between the connecting pipe 32 and the fixed pipe 302 and between the fixed pipe 302 and the bridging pipe 301 to avoid water leakage.

[0026] Preferably, the water delivery ring 2 at the top is a hard water delivery ring 2, which can be used to initially limit the shape of the spray unit. The water delivery ring 2 at the top is a hard water delivery ring 2. The cross section of the water delivery ring 2 can be a center of a circle or a polygon. Since the cross section of the trunk is circular, the water delivery ring 2 is preferably circular so that the spray heads 21 can be evenly distributed around the trunk. If other columns other than the trunk are used for planting in three-dimensional planting of Dendrobium, the cross-sectional shape of the water delivery ring 2 can be modified accordingly. The water delivery ring 2 of the first layer is a flexible water delivery ring 2, and the water delivery ring 2 is in an unclosed state. When the water delivery ring 2 of the lower layer is installed, after the connecting pipe 3 is installed, the flexible water delivery ring 2 of the lower layer is bent, and the number of connecting pipes 3 on each layer of the water delivery ring 2 is at least three groups, and they are equidistantly distributed along the axis of the water delivery ring 2, and under the action of the connecting pipe 3, it is bent to form a shape closest to the upper water delivery ring 2, so that the dendrobium planted in the lower layer can also receive the spray water source evenly.

[0027] Among them, Figure 2 As shown, in order to prevent the water source from the upper spray irrigation from dripping onto the lower layer of Dendrobium, causing the lower layer of Dendrobium to receive more water, a guide ring 4 with a middle opening is provided on the connecting pipe 3, and the diameter of the guide ring 4 gradually increases from top to bottom. The guide ring 4 can guide the water source dripping from the upper layer, so that it can divert the excess water falling from the upper layer to the part away from the Dendrobium, avoiding accumulation at the Dendrobium below, and the guide ring 4 is made of transparent material, such as acrylic plate, etc., which reduces the obstruction of light to a certain extent, so that part of the light can pass through the guide ring 4 to shine on the lower layer of Dendrobium.

[0028] Preferably, a valve 5 is installed on the water delivery ring 2 located at the top, and by opening and closing the valve 5, a certain spray unit can be opened and closed individually according to the growth conditions of the Dendrobium officinale on a certain tree trunk.

[0029] Preferably, it also includes a mounting frame 6 for suspending the spray unit, and a mounting rod 61 is provided on the uppermost water supply ring 2. During installation, the mounting frame 6 can be connected to the skeleton in the greenhouse, and then the mounting rod 61 is connected to the mounting frame 6 to suspend the spray unit. At the same time, the mounting frame 6 and the mounting rod 61 are detachably connected, and the distance between each group of mounting rods 61 can be adjusted according to the distance between the trunks of the Dendrobium planting trees.

[0030] The above description is only an embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present invention shall be included in the scope of the claims of the present invention.
