[0028] Compared with the prior art, the present application has the following advantages:

[0029] 1. High accuracy. The control is scientific and convenient. Compared with the patent ZL201710241525, the dry depth can be accurate to the millimeter level, and the wet point delay time can be accurate to one minute. The accuracy is high, and the single machine and the network can realize offline or online monitoring of soil moisture content through the Internet of Things.

[0030] 2. High reliability. First, the photovoltaic panel is installed outside the flip cover to collect light for power supply, and the inside is rainproof and sunproof, which avoids water, sun exposure, and high temperature of the circuit board, battery, and display screen, and prolongs the service life. Second, the embedded body: the upward face can accommodate the battery, display screen, and keys, and the downward face can accommodate the circuit board and its display screen and keys. Third, the shell: the inside is waterproof, and the electric actuator and wires can be installed outside.

[0031] 3. High irrigation performance. For large-area drip irrigation, there is no need to control the flow by mobile phone APP control wheel irrigation, but only to control irrigation by meeting the root zone water content and other parameters. The ball valve with larger effective diameter than the electromagnetic valve is adopted to prevent clogging and improve irrigation efficiency. It can also realize large-aperture high-fertilizer-efficiency drip irrigation.

[0032] 4. Light simplification. The integrated structure is adopted to avoid separation of the main body of the intelligent irrigation robot, the soil moisture detection sensor and the control circuit board, which is convenient for packaging, transportation and installation.

[0033] 5. High cost performance. Due to the light and simple structure of the present application, the cost is low, and the irrigation is accurate, reliable and high in performance, so the cost performance is high. BRIEF DESCRIPTION OF DRAWINGS

In the control of the irrigator, the prior art generally uses multi-point moisture content control, but due to the differences in the planted plants, soil environment (soil, terrain, orientation, etc.), microclimate, it is difficult to realize the personalized data collection of the minimum unit irrigation area, wherein in the Chinese patent "intelligent water-saving irrigation system and method based on dry depth-time domain control" (patent number ZL201710241525), the dry-wet probe is buried in the irrigation soil at a pre-set depth, and this depth is used as the threshold of the dry depth, while the soil dry depth and the growth of the crop root system change with time, and the depth of the dry-wet probe needs to be adjusted accordingly, which brings inconvenience to the use.

[0054] Referring to Figures 1-4 The working principle of the intelligent irrigation robot of the embodiment is as follows:

When the soil layer is dry to a certain degree and depth from the surface, the plants and crops are subjected to a certain water stress, the root system is promoted to develop, and the soil is kept moderately dry and ventilated, which is beneficial to reduce the moldy roots and diseases and pests of the plants and crops. When the sensing parameters such as the dry depth or the root zone water content reach the set threshold, the control circuit board 15 receives the signal of the soil moisture detection sensor 7, and then sends a corresponding instruction to the switch driving mechanism, and the switch driving mechanism drives the switch end of the valve 1 to open to perform irrigation. When the dry depth or the root zone water content reaches the set threshold, the control circuit board 15 prolongs the valve 1 to close for a certain time according to the set delay to stop irrigation, so as to ensure the necessary wetness and water holding capacity of the soil without wasting water. At the same time, the opening and closing of the valve 1 are controlled by the control circuit board 15 and the switch driving mechanism, so that the digital deficit irrigation is realized.

[0056] Further, on the one hand, the shell composed of the flip cover 2, the embedded body 3, and the shell 4 can protect the internal structure and electrical elements, avoid damage to the internal structure by environmental factors such as sunlight, rain, and dust, and is beneficial to prolong the service life, wherein the openable flip cover 2 can be opened to set parameters of the control circuit board 15 arranged in the embedded body 3, and can be closed to cover and protect the embedded body 3 and the internal components thereof; the embedded body 3 is embedded in the top of the shell 4, so that the components arranged in the embedded body 3 and the components located in the shell 4 are in the enclosed space, and are thus covered and protected. On the other hand, a first heat dissipation gap 5 is reserved between the top surface of the shell 4 and the bottom surface of the embedded body 3, heat dissipation holes 4-2 are arranged between the two adjacent mounting bosses 4-1, and a second heat dissipation gap 6 is arranged between the protective wall 4-3 and the inner wall of the embedded body 3, so as to form a heat dissipation channel that is ventilated and rainproof, and that connects the outside and the inner cavity of the shell 4 and the embedded body 3, and forms a channel for convective heat dissipation with the ambient air, thereby prolonging the service life of the battery and other electrical elements, avoiding the failure of the battery due to high temperature, and being very ingenious.

[0057] In addition, in case of irrigation failure, the T-shaped screw 19 can be rotated in the corresponding direction to move the rotation stopping boss 21 on the valve 1 away from the rectangular structure of the circular ring sleeve 18, that is, the circumferential direction limiting between the shell 4 and the valve 1 is released; the valve 1 can be opened and closed by manually rotating and twisting the shell 4 in the forward and reverse directions, so as to realize emergency irrigation, which is very ingenious and convenient, and avoids the disadvantages of heavy, high energy consumption, and inconvenience of mobile irrigation robots.
