When the soil humidity is low, the controller controls the output end of the driving motor to rotate, and the output end of the driving motor drives the secondary screw to rotate. The thread groove on the surface of the secondary screw drives the driving block to move, and the driving block drives the opening and closing head to move, so that the tapered end of the opening and closing head gradually moves away from the secondary connecting pipe, and the opening and closing head and the secondary connecting pipe are opened. Water and fertilizer are transported to the drainage port through the delivery port on the opening and closing head, and the water and fertilizer flow into the external pipe and the guiding hollow plate, and the water and fertilizer drip out through the dripper to over-irrigate the soil in the area. When the drip irrigation makes the soil reach a predetermined humidity threshold, the controller drives the driving motor to rotate in the opposite direction, resets the opening and closing head, and stops water and fertilizer irrigation, thereby completing the intelligent water and fertilizer irrigation for fruit tree planting, preventing the fruit trees from rotting their roots, and saving the use of water and fertilizer.

[0016] 2. In the present invention, when the secondary screw is rotating, the transmission rod is driven to rotate at the same time, the transmission rod drives the primary bevel gear to rotate, the primary bevel gear drives the secondary bevel gear to rotate, the secondary bevel gear drives the primary screw to rotate, the primary screw drives the rotating tube to move, the primary screw drives the lifting block to move downward, the lifting block drives the two filter cotton plates to unfold under the action of two guide grooves through two connecting bars, so that the two filter cotton plates are attached to the upper side of the dripper, the impurities in the water and fertilizer are filtered, and the dripper is prevented from being blocked. When the irrigation is completed, the driving motor is reversed, and the filter cotton plates are reset at this time, and are close to each other to squeeze out the water and fertilizer therein, and the external pipe and the guide hollow plate are emptied to make the inside dry, so as to avoid the water and fertilizer being retained inside to cause the growth of algae and moss, thereby blocking the dripper.

[0017] 3. The present invention manually rotates the fixed threaded rod to disengage the positioning ear, and then manually rotates the mounting plate. The mounting plate drives two driving rods to move through two driving ports, and the two driving rods drive two sliders to move away from each other, and the two sliders drive two clamping plates to move away from each other, thereby releasing the fixation of the external tube, and then removing the external tube, thereby achieving the effect of quickly disassembling and installing the external tube.

When the soil humidity is low, the controller 13 controls the output end of the drive motor 15 to rotate, and the output end of the drive motor 15 drives the secondary screw 30 to rotate. The thread groove on the surface of the secondary screw 30 drives the drive block 31 to move, and the drive block 31 drives the opening and closing head 21 to move, so that the tapered end of the opening and closing head 21 gradually moves away from the secondary connecting pipe 22, and the opening and closing head 21 and the secondary connecting pipe 22 are opened.

When the drip irrigation makes the soil reach a predetermined humidity threshold, the controller 13 drives the drive motor 15 to rotate in the opposite direction, resets the opening and closing head 21, stops the water and fertilizer irrigation, and empties the external pipe 6 and the guide hollow plate 11 to dry the inside, thereby completing the intelligent water and fertilizer irrigation for fruit tree planting; When the secondary screw 30 is rotating, it drives the transmission rod 25 to rotate at the same time, the transmission rod 25 drives the primary bevel gear 24 to rotate, the primary bevel gear 24 drives the secondary bevel gear 26 to rotate, the secondary bevel gear 26 drives the primary screw 19 to rotate, the primary screw 19 drives the rotating tube 42 to move, the primary screw 19 drives the lifting block 45 to move downward, the lifting block 45 drives the two filter cotton plates 38 to unfold through the two connecting strips 41 under the action of the two guide grooves 40, so that the two filter cotton plates 38 are attached to the upper side of the dripper 18 to filter the impurities in the water and fertilizer to prevent the dripper 18 from being blocked. When the irrigation is finished, the driving motor 15 is reversed, and the filter cotton plates 38 are reset at this time, and are close to each other to squeeze out the water and fertilizer therein to prevent internal moisture and avoid the growth of algae and mosses; When the external tube 6 needs to be disassembled and replaced or directly removed and not used, first manually rotate the fixing threaded rod 36 to disengage the fixing threaded rod 36 from the positioning ear 37, release the limit of the mounting plate 14, and then manually rotate the mounting plate 14, the mounting plate 14 drives the two driving rods 35 to move through the two driving ports 20, the two driving rods 35 respectively drive the two sliders 34 away from each other, the two sliders 34 respectively drive the two clamping plates 33 away from each other, the external tube 6 is released from fixation, and then the external tube 6 is removed to complete the quick disassembly.

When the device is used, first move the device to the ground where the fruit trees are cultivated, and then adjust the multiple humidity sensors 7 to different heights by adjusting the height adjustment device, so that the detection ends are inserted and planted in the soil close to the fruit trees, separate the lower pressing plate 9 from the water and fertilizer tank 1, and then introduce the water and fertilizer required for drip irrigation into the water and fertilizer tank 1, and then use the lower pressing plate 9 to close the water and fertilizer tank 1 to complete the installation of the device; S2. When in use, the humidity of the fruit tree soil is first monitored by the humidity sensor 7, and the data is transmitted to the controller 13. When the soil humidity is low, the controller 13 controls the driving component to drive the opening and closing head 21 to move, so that the tapered end of the opening and closing head 21 gradually moves away from the secondary connecting pipe 22. At this time, the opening and closing head 21 and the secondary connecting pipe 22 are opened, and the water and fertilizer are transported to the drainage port 28 through the delivery port 27 on the opening and closing head 21, and the water and fertilizer are transported to the drip irrigation nozzle through the secondary connecting pipe 22, and the water and fertilizer are drip-irrigated through the drip irrigation nozzle to complete the drip irrigation of the fruit tree; S3.
