However, after understanding the disclosure of the present application, various changes, modifications, and equivalents of the methods, devices, and / or systems described herein will be apparent. For example, the order of operations described herein is merely illustrative and is not limited to the order set forth herein. Rather, changes that will be apparent after understanding the disclosure of the present application may be made, except for operations that must occur in a specific order. In addition, descriptions of features known in the art may be omitted for the sake of clarity and conciseness.

[0029] The features described herein may be implemented in different forms and should not be construed as limited to the examples described herein. Rather, the examples described herein are provided only to illustrate some of the many possible ways of implementing the methods, devices, and / or systems described herein that will be apparent after understanding the disclosure of the present application.

[0030] Throughout the specification, when an element (such as a layer, region, or substrate) is described as "on" another element, "connected to" another element, "coupled to" another element, "above" another element, or "covering" another element, it may be directly "on" another element, "connected to" another element, "coupled to" another element, "above" another element, or "covering" another element, or there may be one or more other elements intervening therebetween. In contrast, when an element is described as "directly on" another element, "directly connected to" another element, "directly coupled to" another element, "directly above" another element, or "directly covering" another element, there may be no other elements intervening therebetween.

[0031] As used herein, the term "and / or" includes any one of the listed related items and any combination of any two or more of them.

[0032] Although terms such as "first", "second", and "third" may be used herein to describe various components, elements, regions, layers, or sections, these components, elements, regions, layers, or sections are not limited by these terms. Rather, these terms are only used to distinguish one component, element, region, layer, or section from another. Thus, a first component, element, region, layer, or section as referred to in the examples described herein may also be referred to as a second component, element, region, layer, or section without departing from the teachings of the examples.

[0033] For ease of description, spatial relationship terms such as "above", "upper", "below", and "lower" may be used herein to describe the relationship of one element to another as shown in the figures. Such spatial relationship terms are intended to include different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is flipped, an element described as "above" or "upper" relative to another element will then be "below" or "lower" relative to the other element. Thus, the term "above" includes both the orientation of "above" and "below" depending on the spatial orientation of the device. The device may also be positioned in other ways (e.g., rotated 90 degrees or in other orientations), and the spatial relationship terms used herein will be interpreted accordingly.

[0038] In the following description, reference will be made to Figures 1 to 8 specifically describe the detailed structures of the frame part 1 and the conveying pipeline part 2 of the water and fertilizer integrated fertilization device.

[0039] As Figure 1 and Figure 2 shown, in the embodiment, the frame part 1 can be formed into a frame structure assembled by multiple steel materials, and the assembling method can be welding or using fastening bolts. The conveying pipeline part 2 is arranged on the frame part 1, and the frame part 1 can play a supporting role.

The main liquid supply pipeline is used for supplying water, and at the same time, water and fertilizer can be mixed in this pipeline to obtain water-soluble fertilizer and liquid fertilizer; the fertilizer supply pipeline is used for supplying fertilizer, and mixes water and fertilizer together and transports them to the main liquid supply pipeline, so that water and fertilizer form water-soluble fertilizer and liquid fertilizer.

[0040] Specifically, the main liquid supply pipeline can include a main pipeline assembly 301, a mixer 302 and a first connecting member 303. The mixer 302 and the first connecting member 303 are arranged on the main pipeline assembly 301 in sequence along the liquid flow direction. The liquid flow direction can be understood as the flow direction of the liquid in the main liquid supply pipeline. The main pipeline assembly 301 can include multiple straight pipes and multiple bent pipes. The interiors of the straight pipes and the bent pipes are hollow for the passage of liquid. The straight pipes and the bent pipes can form a pipeline made of PVC (polyvinyl chloride). The connection method of the multiple straight pipes and the multiple bent pipes can be to use a special PVC connection glue for connection and sealing. In addition, the main pipeline assembly 301 can also include necessary connection elements such as connection heads and connection flanges. Since these elements are common components in the prior art and are also commonly used components for pipeline connection, those skilled in the art can make specific selections according to needs. For example, when connecting to the mixer 302, a connection method of the connection head and the pipeline is required, and when connecting to the following supply pump 402, a connection flange is required. The structures of these pipelines and the connection components will not be described in detail here. The main pipeline assembly 301 can be used for the passage of liquid. Similarly, in the following description, for pipeline components such as a branch pipeline assembly 401, a mixing pipeline assembly 403, a first branch 404 and a second branch 405, the structures of these pipeline components will not be described one by one, and those skilled in the art can know. In addition, the mixer 302 can be, for example, a common mixing component in the prior art, such as a K-shaped mixer.

The branch pipeline assembly 401 is used to extract fertilizer and transport the fertilizer to the mixing pipeline assembly 403. The main liquid supply pipeline supplies water into the branch pipeline assembly 401 through the first connector 303, and enables the liquid mixture of water and fertilizer to flow to the mixing pipeline assembly 403. Then, the liquid mixture of water and fertilizer in the mixing pipeline assembly 403 is further mixed by the mixer 302 to obtain water-soluble fertilizer and liquid fertilizer, which are output from the main liquid supply pipeline to achieve fertilization. The first connector 303 can be, for example, a three-way valve.

[0042] The overall structure of this integrated water and fertilizer fertilization device is simple, and it is convenient for users to operate. It can quickly and conveniently mix water and fertilizer through the conveying pipeline part 2, and obtain water-soluble fertilizer and liquid fertilizer to meet the fertilization requirements.
