[0002] Water is a necessary substance for the growth of crops. Agricultural water consumption accounts for 70% of my country's water consumption. However, with the development of industry, the supply of agricultural water has become less and less, and agricultural water use is threatened. We urgently need to alleviate the current water shortage by improving agricultural water use efficiency and saving irrigation water. In order to prevent the rapid evaporation of water irrigated on the surface, some irrigation devices have appeared on the market that irrigate water into the soil for better absorption by the roots of crops.

[0003] When the current underground alternating irrigation device is in use, the cylinder used for irrigation is inserted into the soil, and then the sprinkler head is moved out of the cylinder to irrigate water into the soil. Because the root system of crops is complex and grows in different directions inside the soil, today's irrigation devices cannot evenly irrigate the soil in all directions, which is not convenient for crop roots to absorb. Moreover, when the sprinkler head is moved out of the cylinder, the soil is pressed into the sprinkler hole, causing the sprinkler pipe to be blocked, which will cause the irrigation blockage problem.

At this time, the first rotating rod, the first gear, the second gear and the first gear plate can drive several drainage frames to move out of the drill tube together, so that the drainage holes face all directions around the drill tube;

[0019] S2: Water and pesticides can be poured into the water barrel together through the water inlet assembly, and then the third gear is driven to rotate by the dual-axis motor, and the first tooth groove is used to drive the toothed disc to roll along the inner wall of the water barrel, and finally the stirring blade is driven to roll to stir and mix the water and pesticides;

[0020] S3: After the water and pesticide are mixed, they will continue to enter the rotating pipe through the rotating sleeve under the pressure of the water pump connected to the water inlet pipe, and finally enter the drainage frame inserted into the soil around the drill tube through the water storage box and the water outlet pipe, and spray water to various positions around the soil through the drainage holes on the surface of the drainage frame;

[0021] S4: When the drill tube is driven downward by the cylinder, the scraper sleeve can be driven to rotate against the surface of the drill tube through the second tooth plate, the second rotating rod, the fourth gear, the driven bevel gear, the third rotating rod, the driving bevel gear and the fifth gear, so that the scraper sleeve moves vertically and rotates relative to the drill tube to scrape off the sludge attached to the surface of the drill tube;

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. Through the provided irrigation mechanism, the support frame is first moved to the position where irrigation is required, and the cylinder is started to drive the drill tube to drill into the soil. Then, the provided squeezing mechanism can drive several drainage frames to move out of the drill tube together, so that several drainage holes face all directions around the drill tube. Then, the provided water inlet assembly is used to discharge water into the soil from the drainage holes on the surface of each drainage frame, so that water can be irrigated in all directions around the drill tube. When the drainage frame is inserted into the soil, the drainage holes on its surface will not be blocked due to squeezing the soil, which solves the problem that the irrigation device in the prior art cannot drain water in all directions around the soil and the drainage holes of the irrigation device are easily blocked due to squeezing the soil.

[0025] 2. Water and pesticides can be poured into the water barrel together through the water inlet assembly, and then the dual-axis motor can be started. The water and pesticides discharged into the water barrel can be stirred in multiple directions through the third gear, the first tooth groove, the toothed disc, the stirring rod and the stirring blade, so as to facilitate the rapid mixing of water and pesticides. The mixed fertilizer water can then be passed into the drainage frame through the provided connecting piece, thereby improving the absorption effect of crops.

[0026] 3. When the drill barrel is driven downward by the cylinder, the scraper sleeve can be driven to rotate against the surface of the drill barrel through the second tooth plate, the second rotating rod, the fourth gear, the driven bevel gear, the third rotating rod, the active bevel gear and the fifth gear, so that the scraper sleeve can move vertically and rotate relative to the drill barrel, so as to scrape off the sludge attached to the surface of the drill barrel, keep the equipment clean and tidy, and facilitate subsequent use.

[0027] 4. When the drill tube is pushed into the soil, the second tooth plate that moves downward can also drive the slide to move downward. At this time, the downward slide can also drive the moving wheel to flip off the ground through the third tooth plate, the incomplete gear, and the mounting frame, so that the bottom of the support frame contacts the ground, thereby improving the stability of the support frame. The downward slide can also allow several positioning piles to be inserted into the soil to fix the support frame, thereby further improving the stability of the support frame.

At this time, the gear ring 7 will drive the first rotating rod 9 with the first gear 902 to rotate, and the first rotating rod 9 will drive the drainage frame 5 with the first tooth plate 502 to move through the second gear 901, so as to drive the multiple drainage frames 5 on the side wall of the drill tube 3 to slide out in all directions around the drill tube 3 and insert into the soil. At this time, water and pesticides are respectively introduced into the water barrel 4 through the two water inlet pipes 402 for mixing, and then the mixed liquid is subjected to the pressure of the water pump connected to the water inlet pipe 402, and will continue to The water then enters the cavity 1001 inside the rotating sleeve 10 through the connecting pipe 11, flows into the rotating pipe 601 through the water inlet 6011, and finally enters the drainage frame 5 through the water storage box 8 and the water outlet pipe 801, and flows into the soil from the drainage holes 501 on the surface of the drainage frame 5. When the drainage frame 5 is horizontally inserted into the soil, the soil is squeezed through its side walls, and the drainage holes 501 are provided on the surface of the drainage frame 5 and will not be squeezed by the soil. Therefore, the soil will not be blocked in the drainage holes 501, so that the soil can be irrigated in all directions without clogging the drainage holes 501, thereby facilitating absorption by the roots of crops.

At this time, the third gear 12 will drive the two tooth discs 13 to roll along the inner wall of the water cylinder 4, and then can drive the stirring rod 1301 and the stirring blades 1302 to roll to stir the water and pesticide in the water cylinder 4 in multiple directions, thereby increasing the mixing speed of water and pesticide, and facilitating the irrigation of the liquid medicine into the soil for better absorption by crops.

[0049] like Figure 3 , Figure 4 and Fig. 9 As shown, as a preferred embodiment, on the basis of the above-mentioned manner, further, a wall scraping mechanism is arranged between the support frame 1 and the drill tube 3, and the wall scraping mechanism includes a fixed plate 101 arranged on the inner wall of both sides of the support frame 1, a scraping sleeve 14 rotatably arranged between the two fixed plates 101, and a transmission component arranged on the fixed plate 101 and capable of driving the scraping sleeve 14 to rotate relative to the drill tube 3 when the drill tube 3 moves vertically;

[0050] The transmission assembly includes a second tooth groove 1401 arranged on the outer wall of the scraper sleeve 14, a second rotating rod 15 rotatably arranged on the top of the fixed plate 101, a fourth gear 1501 arranged on the rod wall of the second rotating rod 15 and meshing with the second tooth groove 1401, a driven bevel gear 1502 arranged on the top of the second rotating rod 15, a third rotating rod 16 arranged on the inner wall of the support frame 1, an active bevel gear 1601 arranged on the rod wall of the third rotating rod 16 and meshing with the driven bevel gear 1502, a second tooth plate 17 arranged on the top of the drill tube 3, and a fifth gear 1602 arranged on the rod wall of the third rotating rod 16 and meshing with the second tooth plate 17;

[0051] When the cylinder 2 drives the drill barrel 3 to move up and down, the drill barrel 3 will drive the third rotating rod 16 provided with the fifth gear 1602 to rotate through the second tooth plate 17, and the third rotating rod 16 will drive the second rotating rod 15 provided with the driven bevel gear 1502 to rotate through the active bevel gear 1601, and the second rotating rod 15 will drive the scraper sleeve 14 provided with the second tooth groove 1401 to rotate through the fourth gear 1501. Therefore, when the drill barrel 3 moves up and down, the scraper sleeve 14 can move up and down and rotate relative to the drill barrel 3, so that the soil attached to the outer wall of the drill barrel 3 can be scraped off thoroughly, keeping the equipment clean and tidy for subsequent use. In addition, in order to prevent the components of the transmission assembly from being touched by foreign objects and affecting the normal operation of the equipment, a cover body 1011 can be installed on the fixed plate 101 to shield the components.

[0052] like Figure 2 , Figure 8 and Fig.10 As shown, as a preferred embodiment, on the basis of the above-mentioned manner, further, a mounting cavity 102 is provided inside the support frame 1, a positioning assembly is provided inside the mounting cavity 102, the positioning assembly comprises a slide seat 18 slidably provided on the inner wall of the mounting cavity 102 and connected to the bottom of the second tooth plate 17, and a plurality of positioning piles 1801 provided at the bottom of the slide seat 18, and a plurality of slots matching the positioning piles 1801 are provided at the bottom of the mounting cavity 102;

[0053] A moving assembly is also provided at the bottom of the support frame 1, and the moving assembly includes a movable groove 103 opened at the edges of both sides of the bottom of the support frame 1, a mounting frame 19 rotatably arranged on the inner wall of the movable groove 103, a moving wheel 1901 arranged on the inner wall of the mounting frame 19, an incomplete gear 20 coaxially arranged with the mounting frame 19, and a third tooth plate 21 arranged on the side wall of the slide 18 and meshing with the incomplete gear 20;

[0054] The movable wheel 1901 is arranged to facilitate pushing the support frame 1 to transfer the equipment. When the support frame 1 is moved to the designated position and the drill tube 3 is pushed into the soil, the drill tube 3 will also drive the slide 18 to move downward through the second tooth plate 17, and the slide 18 will drive the incomplete gear 20 to rotate through the third tooth plate 21, and the incomplete gear 20 will drive the mounting frame 19 and the movable wheel 1901 to flip over and leave the ground. At this time, the bottom of the support frame 1 is in contact with the ground, which can improve the stability of the support frame 1 and the equipment, and prevent the movable wheel 1901 from rolling due to the reaction force when the drill tube 3 is inserted into the soil. When the incomplete gear 20 rotates to the side without teeth and contacts the third tooth plate 21, the third tooth plate 21 drives the incomplete gear 20 to continue to rotate, thereby preventing the flipped mounting frame 19 and the movable wheel 1901 from continuing to rotate, and the downward-moving slide 18 will also drive a number of positioning piles 1801 to penetrate into the soil to fix the support frame 1, thereby further improving the stability of the equipment.

[0055] The working principle of the present invention is as follows: when it is necessary to irrigate the soil, the support frame 1 is first moved to the position where irrigation is required, and then the cylinder 2 is started to work, and the drill tube 3 is pushed into the soil through the piston rod 201. After the drill tube 3 is pushed into the soil, the dual-axis motor 6 is started to work to drive the rotating tube 601 to rotate, and the rotating tube 601 will continue to drive the gear ring 7 to rotate through the curved rod 602. At this time, the gear ring 7 will drive the first rotating rod 9 with the first gear 902 to rotate, and the first rotating rod 9 will drive the drainage frame 5 with the first tooth plate 502 to move through the second gear 901, so that the multiple drainage frames 5 on the side wall of the drill tube 3 can be driven to slide out in all directions around the drill tube 3 and inserted into the soil. At this time, water and pesticides are respectively passed through the two water inlet pipes 402. The mixed liquid medicine is mixed in the water cylinder 4, and then the mixed liquid medicine is subjected to the pressure of the water pump connected to the water inlet pipe 402, and will continue to enter the cavity 1001 inside the rotating sleeve 10 through the connecting pipe 11, and then flow into the rotating pipe 601 through the water inlet 6011, and finally pass through the water storage box 8 and the water outlet pipe 801 into the drainage frame 5, and flow into the soil from the drainage hole 501 on the surface of the drainage frame 5, because when the drainage frame 5 is horizontally inserted into the soil, the soil is squeezed through its side wall, and the drainage hole 501 is opened on the surface of the drainage frame 5 and will not be squeezed by the soil, so the soil will not be blocked in the drainage hole 501, so that the soil can be irrigated in all directions, and the drainage hole 501 will not be blocked, which is convenient for the root system of crops to absorb. When the cylinder 2 drives the drill barrel 3 to move up and down, the drill barrel 3 will drive the third rotating rod 16 provided with the fifth gear 1602 to rotate through the second tooth plate 17, and the third rotating rod 16 will drive the second rotating rod 15 provided with the driven bevel gear 1502 to rotate through the active bevel gear 1601, and the second rotating rod 15 will drive the scraper sleeve 14 provided with the second tooth groove 1401 to rotate through the fourth gear 1501. Therefore, when the drill barrel 3 moves up and down, the scraper sleeve 14 can move up and down and rotate relative to the drill barrel 3, so that the soil attached to the outer wall of the drill barrel 3 can be scraped off thoroughly, keeping the equipment clean and tidy for subsequent use. Moreover, when the drill tube 3 is pushed into the soil, the drill tube 3 will also drive the slide 18 to move downward through the second tooth plate 17, and the slide 18 will drive the incomplete gear 20 to rotate through the third tooth plate 21, and the incomplete gear 20 will drive the mounting frame 19 and the moving wheel 1901 to flip over and leave the ground. At this time, the bottom of the support frame 1 is in contact with the ground, which can improve the stability of the support frame 1 and the equipment, and prevent the moving wheel 1901 from rolling due to the reaction force when the drill tube 3 is inserted into the soil. When the incomplete gear 20 rotates to the side without teeth and contacts the third tooth plate 21, the third tooth plate 21 drives the incomplete gear 20 to continue to rotate, thereby preventing the flipped mounting frame 19 and the moving wheel 1901 from continuing to rotate, and the downward-moving slide 18 will also drive a number of positioning piles 1801 to penetrate into the soil to fix the support frame 1, thereby further improving the stability of the equipment.

[0056] The present invention also discloses an irrigation method of an adjustable underground alternating irrigation device, comprising the following steps:

[0057] S1: Move the support frame 1 to the position where irrigation is required, start the cylinder 2 to drive the drill tube 3 to drill into the soil, and then drive the gear ring 7 on the inner wall of the drill tube 3 to rotate through the dual-axis motor 6. At this time, the first rotating rod 9, the first gear 902, the second gear 901 and the first gear plate 502 can drive several drainage frames 5 to move out of the drill tube 3 together, so that several drainage holes 501 face all directions around the drill tube 3;
