[0024] The cover 532 is fixedly connected to the carrier ring 5313 by bolts. A hole is opened in the top shell wall of the cover 532. The top end of the sleeve 534 passes through the hole and is rotatably connected to the hole by a bearing. The top end of the drive shaft 535 passes through the top shell wall of the sleeve 534. Multiple scraping strips 536 are located above the cover 532 and are used to scrape the outer surface of the cover 532. Each scraping strip 536 has a double-sided wedge integrally provided at its bottom end. The bottom of the double-sided wedge is used to scrape the top shell wall of the carrier ring 5313.

A return spring located on the round rod 5393 is sleeved between the fixing ring 5394 and the irregularly shaped block 5392 above. The upper spherical sealing plug 5395 makes contact with the inclined surface of the double-sided wedge. When the double-sided wedge contacts the upper spherical sealing plug 5395, the inclined surface of the double-sided wedge applies force to it, which in turn causes the spherical sealing plug 5395 to move the round rod 5393 downward, stretching the return spring. At this time, the spherical sealing plug 5395 on the other end of the round rod 5393 moves downward as well. After the upper spherical sealing plug 5395 moves downward, it seals the upper irregular block 5392, while after the lower spherical sealing plug 5395 moves downward, it releases the seal on the lower irregular block 5392, thereby allowing the liquid in the discharge pipe 5391 to be discharged into the surrounding soil.

[0028] The working principle of this invention is as follows: When arranging the product, each irrigation and fertilization component 200 is placed on the planting ground according to the position of the plant. The irrigation and fertilization component 200 encircles the plant and then the positioning pin on the liquid distribution box 1 is inserted into the soil to limit the position of the irrigation and fertilization component 200. When the positioning pin is inserted into the soil, the multiple soil loosening parts 4 on the movable ring 2 also move accordingly. When the bottom of the liquid distribution box 1 contacts the soil, the insertion of the irrigation and fertilization component 200 stops. At this time, the tips of the soil loosening nails in each soil loosening part 4 are inserted into the soil. Next, according to the current growth stage of the plant, the movable ring 2 in the arranged irrigation and fertilization component 200 is adjusted. As the movable ring 2 rotates, the various arc-shaped grooves on it are adjusted. At this time, the protruding rods connected to the arc-shaped grooves move accordingly, driving the corresponding guide 3 to be added to the position. When the movable ring 2 moves, the various soil loosening components 4 arranged on it move accordingly, thereby scraping and loosening the surface soil. After the positions of each guide 3 are adjusted, each of the multiple irrigation and fertilization mechanisms 5 to be inserted into the soil is inserted into the soil near the plant by hand through the constraint ring in the corresponding guide 3. At this time, if only shallow insertion of the irrigation and fertilization mechanism 5 in the soil is required, and the soil is soft, the driving member 538 in the tail end assembly 53 of the irrigation and fertilization mechanism 5 does not need to be started by the external controller body, and manual force is sufficient. If deep insertion of the irrigation and fertilization mechanism 5 into the soil is required, the motor 5383 in the driving member 538 needs to be started by the external controller body to drive the gear 5382 to move counterclockwise. At this time, the external gear ring 5381 engaged therewith moves, thereby driving the sleeve 534 to rotate clockwise. When the sleeve 534 rotates clockwise, the spring expansion rods 5372 arranged thereon in the switching member 537 cooperate with the accommodating grooves in the switching disc 5371, so that the switching disc 5371 drives the transmission shaft 535 to rotate synchronously. The bottom end of the transmission shaft 535 is inserted into the tapered drill bit body 5312 in the tapered member 531, thereby driving the tapered drill bit body 5312 to rotate. At this time, the irrigation and fertilization mechanism 5 is manually held, the tail end assembly 53 is inserted through the restraint ring of the guide 3, and the tapered drill bit body 5312 in the tapered member 531 contacts the soil. Under the condition of manual holding, the movement of the tapered drill bit body 5312 enables the irrigation and fertilization mechanism 5 to be quickly inserted into the soil, thereby achieving convenient arrangement of the irrigation and fertilization mechanism 5. After the irrigation and fertilization mechanism 5 is arranged, the driving member 538 in the irrigation and fertilization mechanism 5 is closed by the external controller body. When each irrigation and fertilization mechanism 5 is arranged in the soil, the irrigation and fertilization mechanisms 5 are communicated with the distribution box 1 in the irrigation and fertilization component 200 through a hose, and then the irrigation and fertilization component 200 is communicated with the pipeline 100 through a flow guide pipe. When irrigation and fertilization of the plants is required, the fertilizer is mixed with the water resource in the storage container to form liquid fertilizer, and then the mixed liquid is pumped into the pipeline 100 by the water pump body started by the external controller body. The liquid in the pipeline 100 enters the distribution box 1 in the corresponding irrigation and fertilization component 200 through each flow guide pipe, and then enters the corresponding irrigation and fertilization mechanism 5 through each hose under the action of water pressure. When the controller body starts the water pump body, the driving member 538 of the tail end assembly 53 in each irrigation and fertilization mechanism 5 in the irrigation and fertilization component 200 is started synchronously. The motor 5383 in the driving member 538 moves clockwise, thereby driving the gear 5382 to move synchronously. At this time, the external gear ring 5381 engaged therewith drives the sleeve 534 to move counterclockwise. The counterclockwise movement of the sleeve 534 causes the spring expansion rods 5372 in the switching member 537 to move synchronously. When the spring expansion rods 5372 move counterclockwise, they move along the peripheral wall of the switching disc 5371, thereby not driving the transmission shaft 535 to rotate. When the sleeve 534 rotates, the plurality of scraping strips 536 arranged thereon move accordingly, the movement of each scraping strip 536 disturbs the liquid entering the irrigation and fertilization mechanism 5, accelerates the mixing effect of the fertilizer and the liquid inside, and the movement of the scraping strip 536 scrapes the outer surface of the cover 532, thereby preventing the rapid precipitation of the fertilizer in the liquid and ensuring that the fertilizer is applied to the soil near the plants to the greatest extent; When the scraping strip 536 rotates, the double-sided wedge block thereon moves in a circular motion and intermittently contacts the spherical blocking plug 5395 above each discharging member 539, the inclined surface of the double-sided wedge block extrudes the spherical blocking plug 5395, thereby causing the round rod 5393 to move downward under stress, stretching the return spring, at this time, the spherical blocking plug 5395 on the top end of the round rod 5393 blocks the special-shaped block 5392 above, and the spherical blocking plug 5395 on the bottom end of the round rod 5393 moves downward and then moves away from the special-shaped block 5392 below, and then the liquid between the two special-shaped blocks 5392 is released to the surrounding soil; The amount of irrigation and fertilization required by the plants in different growth periods is controlled by the control program in the external controller body, especially the operation time of the water pump body, thereby realizing the control of the amount of irrigation and fertilization.

[0029] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto, any person skilled in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
