Description

Technical Field

[0001] This invention relates to the field of irrigation equipment technology, and in particular to a water-saving sprinkler irrigation device for greening the Gobi Desert and its usage method. Background Technology

[0002] The Gobi Desert is at the forefront of desertification. Greening can fix shifting sand, reduce the frequency and intensity of sandstorms, and protect surrounding farmland, cities and transportation routes.

[0003] Existing Gobi Desert afforestation projects include the planting of drought-resistant trees. These trees require irrigation during planting to ensure stable growth. Patent CN219069087U discloses a water-saving sprinkler irrigation device for landscaping. This device uses a funnel-shaped collection structure to collect rainwater. The funnel's arc-shaped plate increases its area, allowing for the collection of more rainwater. This collected rainwater is then used to irrigate the landscaping, thus saving water resources. A water pump then pumps water through a pipe and sprinklers to irrigate the landscaping. However, because the water is sprayed directly from the sprinklers, the distance between the sprinkler outlet and the irrigated area results in a long water flow path. In the Gobi Desert, due to the climate and rapid air movement, some water is blown away and wasted, while some remains on leaves and trunks and evaporates, leading to significant water waste, reduced irrigation efficiency, and increased water consumption. Summary of the Invention

[0004] This invention provides a water-saving sprinkler irrigation device and its usage method for greening the Gobi Desert, aiming to solve the problems of serious water waste and unsuitability for the wind-blown sand climate of the Gobi Desert mentioned above.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: A water-saving sprinkler irrigation device for afforestation in the Gobi Desert includes a base, on which a water tank and a water pump are fixedly installed. A power supply is also fixedly installed on the base. A bracket is fixedly installed at one end of the base. The horizontal end of the bracket has a horizontal plate that extends and retracts in the vertical direction. The horizontal plate is arranged horizontally and has a semi-circular baffle that moves synchronously closer or further away from the tree via a servo module. When the semi-circular baffle is fully assembled around the tree, it forms a connecting chamber. Multiple sets of spaced-apart spray pipes are connected to the connecting chamber. The connecting chamber is connected to the water pump via a flexible hose. A sand-blowing assembly is slidably installed around an axis inside the baffle. The sand-blowing assembly has a first sand-blowing pipe and a second sand-blowing pipe. The air outlet of the first sand-blowing pipe is close to the tree roots and blows the sand and soil outwards to expose the roots. The air outlet of the second sand-blowing pipe is close to the inner wall of the baffle and cooperates with the baffle to form a back-blowing effect, concentrating the sand and soil backfilling at the roots.

[0006] Preferably, a first electric telescopic rod is fixedly installed at the end of the horizontal section of the bracket, a horizontal plate is fixedly installed at the output end of the first electric telescopic rod, two sets of movable plates are slidably installed on the horizontal plate, and semi-circular baffles with opposite openings are fixedly installed at the ends of the movable plates. A servo module is provided on the horizontal plate to drive the two sets of movable plates to move synchronously in opposite directions.

[0007] Preferably, the connecting chamber is semi-circular and the connecting chamber and the baffle are arranged coaxially, the water spray pipe is set at an angle to the horizontal plane, and the extension line of the water spray pipe interferes with the axis of the connecting chamber.

[0008] Preferably, a semi-circular track is fixedly installed on the inner side wall of the baffle, and a slider is slidably installed on one set of tracks. The slider is equipped with a motor that drives its own movement. When the end faces of the two sets of baffles are in contact, the two sets of tracks form a complete circle. A first sand blowing pipe and a second sand blowing pipe are provided on the slider, and a fan connected to the first sand blowing pipe and the second sand blowing pipe is fixedly installed on the slider.

[0009] Preferably, a gear is fixedly installed at the output end of the motor, and the gear meshes with an incomplete end face gear ring fixedly installed on the inner wall of the baffle. The incomplete end face gear ring is semi-circular and coaxially arranged with the baffle. When the two sets of baffle end faces are in contact, the two sets of incomplete end face gear rings form a complete end face gear ring.

[0010] Preferably, a rotating plate is rotatably mounted on the slider, and a bent structure is provided at the end of the rotating plate away from the slider. A first sand blowing pipe is fixedly mounted on the rotating plate and the first sand blowing pipe is at an angle to the rotating plate. A counterweight block is provided on the slider to limit the position of the rotating plate. A second sand blowing pipe is fixedly mounted on the slider, and the extension line of the second sand blowing pipe passes through the side wall of the baffle.

[0011] Preferably, a mounting plate is fixedly installed on the slider, and a through hole is opened at the end of the mounting plate away from the slider. A pull wire is fixedly connected to the counterweight, and the pull wire passes through the through hole and is fixedly connected to the rotating plate. A vertical rod is fixedly installed on the mounting plate, and the vertical rod is slidably connected to the counterweight. When the rotating plate contacts the mounting plate, the straight segment of the rotating plate near the slider is distributed along the radial direction of the baffle.

[0012] Preferably, a base plate is fixedly installed at the end of the baffle, and a U-shaped closure frame is slidably installed on the base plate via a mounting bracket. An elastic membrane is fixedly installed inside the closure frame, and a second electric telescopic rod that drives the closure frame to move is fixedly installed on the baffle. The two sets of closure frames are of different sizes and the elastic membranes on the two sets of closure frames are of different heights. When the two sets of closure frames come into contact, their parallel sidewalls slide in contact.

[0013] Preferably, one end of one set of elastic membranes away from the second electric telescopic rod is provided with a protrusion, and both ends of the protrusion are fixedly connected to a support rod that is slidably mounted on the closed frame. The support rod is used in conjunction with a limiting push plate fixedly mounted on another set of base plates.

[0014] A method for using a water-saving sprinkler irrigation device for afforestation in the Gobi Desert, comprising the following steps: irrigating and backfilling the roots of trees using the aforementioned water-saving sprinkler irrigation device for afforestation in the Gobi Desert. When in use, add clean water to the water tank, push the base to the location of the green trees that need to be irrigated, adjust the position of the base so that the baffle is on both sides of the tree and the tree is at the symmetrical center of the baffle. Then the servo module drives the two sets of moving plates to move synchronously so that the two sets of baffles approach each other and make contact. Then the first electric telescopic rod drives the horizontal plate to move downward so that the baffle contacts the ground. At this time, the placement of the equipment is completed. The first sand-blowing pipe rotates once, and air is blown out of the first sand-blowing pipe and blown towards the sandy ground at the base of the trees. The air blows away the sand near the base of the trees, and the baffle prevents the blown sand from splashing around randomly. Water is drawn from the tank by a water pump and transported to the connecting room. The water is then sprayed onto the ground at the base of the tree through a sprinkler pipe. The second sand-blowing pipe rotates once, and the air blown out from the second sand-blowing pipe comes into contact with the inner wall of the baffle and then the air flows towards the tree roots. At this time, the sand accumulated on the inner side of the baffle can be blown towards the tree roots to achieve the backfilling of the small trench around the tree roots. After irrigation is complete, the horizontal board moves upward, the two sets of baffles separate, and then the base is pushed to move to other trees for irrigation. During irrigation, water can be sprayed directly onto the roots of the trees.

[0015] The beneficial effects of this invention are: 1. During irrigation, two sets of baffles surround the tree roots to isolate and shield them, with the spray pipes placed inside the baffles to ensure that water is sprayed directly onto the tree roots, effectively shortening the water flow path. Simultaneously, the two sets of baffles shield the tree root area, preventing water splashing caused by wind, thus avoiding water waste and significantly improving the equipment's water-saving effect.

[0016] 2. The air blown out by the first sand blowing pipe clears the sand around the tree roots, forming a small circular trench around the roots. Then, water is sprayed into the trench using a water spray pipe. This not only increases the irrigation depth but also avoids damage to the tree roots, reduces water evaporation, facilitates subsequent water absorption by the trees, and reduces water consumption. After irrigation, the air blown out by the second sand blowing pipe backfills and covers the irrigated area with sand, burying the damp sand and water underneath, further reducing water evaporation and improving the water-saving effect of the equipment.

[0017] 3. The tight fit between the elastic membrane and the baffle forms a closed area, effectively preventing sand from flying outwards during the sand blowing process, ensuring sufficient backfill sand, and reducing the contact between air and the irrigation site, thereby further reducing the water evaporation rate and significantly improving the water-saving effect of the equipment.

[0025] The embodiments will be further described below with reference to the accompanying drawings.

[0026] like Figures 1-6As shown, this invention provides a water-saving sprinkler irrigation device for greening Gobi Desert, comprising a base 1, on which a water tank 2 and a water pump 3 are fixedly installed, and a power supply 4 is fixedly installed. A bracket 5 is fixedly installed at one end of the base 1, and a first electric telescopic rod 6 is fixedly installed on the horizontal section of the bracket 5. A horizontal plate 7 is fixedly installed at the output end of the first electric telescopic rod 6, and two sets of movable plates 8 are slidably installed on the horizontal plate 7. A semi-circular baffle 10 with opposite openings is fixedly installed at the end of the movable plate 8. A servo module 9 is provided on the horizontal plate 7 to drive the two sets of movable plates 8 to move synchronously in opposite directions. A connecting chamber 13 is fixedly installed on the inner wall of the baffle 10, and multiple sets of spaced-distributed water spray pipes 14 are connected to the connecting chamber 13. The connecting chamber 13 is connected to the water pump 3 through a flexible hose. The connecting chamber 13 is semi-circular and coaxially arranged with the baffle 10. The water spray pipes 14 are at an angle to the horizontal plane, and the extension line of the water spray pipes 14 interferes with the axis of the connecting chamber 13.

[0027] In practical application, clean water is added to the water tank 2, and the base 1 is moved to the location of the green tree that needs irrigation. The position of the base 1 is adjusted so that the baffle 10 is located on both sides of the tree and the tree is located at the symmetrical center of the baffle 10. Then, the servo module 9 drives the two sets of moving plates 8 to move synchronously so that the two sets of baffles 10 approach each other and make contact. Then, the first electric telescopic rod 6 drives the horizontal plate 7 to move downward so that the baffle 10 contacts the ground. At this time, the placement of the equipment is completed. The water pump 3 draws water from the water tank 2 and delivers it to the connecting chamber 13. The water is sprayed onto the ground at the tree root position through the water spray pipe 14. After irrigation is completed, the horizontal plate 7 moves upward and the two sets of baffles 10 separate. Then, the base 1 is moved to other trees for irrigation. During irrigation, water can be sprayed directly onto the tree roots, reducing the water flow path. The two sets of baffles 10 shield the tree root area, preventing water from being blown away by the wind, avoiding water waste, and improving the water-saving capacity of the equipment.

[0028] like Figures 1-6 As shown, this invention provides a water-saving sprinkler irrigation device for greening Gobi Desert. A semi-circular track 11 is fixedly installed on the inner wall of the baffle 10. A slider 21 is slidably installed on one set of tracks 11. A motor 25 is installed on the slider 21 to drive its own movement. When the end faces of the two sets of baffles 10 are in contact, the two sets of tracks 11 form a complete circle. A first sand blowing pipe 23 and a second sand blowing pipe 24 are provided on the slider 21. A fan 27 connected to the first sand blowing pipe 23 and the second sand blowing pipe 24 is fixedly installed on the slider 21.

[0029] Specifically, a gear 26 is fixedly installed at the output end of the motor 25. The gear 26 meshes with an incomplete end face gear ring 12 fixedly installed on the inner wall of the baffle 10. The incomplete end face gear ring 12 is semi-circular and coaxially arranged with the baffle 10. When the end faces of the two sets of baffles 10 are in contact, the two sets of incomplete end face gear rings 12 form a complete end face gear ring.

[0030] Specifically, a rotating plate 22 is rotatably mounted on the slider 21. The end of the rotating plate 22 away from the slider 21 is provided with a bent structure. The first sand blowing pipe 23 is fixedly mounted on the rotating plate 22 and the first sand blowing pipe 23 and the rotating plate 22 are provided with an angle. A counterweight block 30 is provided on the slider 21 to limit the position of the rotating plate 22. The second sand blowing pipe 24 is fixedly mounted on the slider 21, and the extension line of the second sand blowing pipe 24 passes through the side wall of the baffle 10.

[0031] Specifically, a mounting plate 28 is fixedly installed on the slider 21. A through hole is opened at the end of the mounting plate 28 away from the slider 21. A pull wire 29 is fixedly connected to the counterweight 30. The pull wire 29 passes through the through hole and is fixedly connected to the rotating plate 22. A vertical rod 31 is fixedly installed on the mounting plate 28. The vertical rod 31 is slidably connected to the counterweight 30. When the rotating plate 22 contacts the mounting plate 28, the straight segment of the rotating plate 22 near the slider 21 is distributed radially along the baffle 10.

[0032] In practical application, in the initial state, under the action of the counterweight 30, the straight section of the rotating plate 22 near the slider 21 is distributed along the radial direction of the baffle 10. When the two sets of baffles 10 move towards the tree, the bent section of the rotating plate 22 first contacts the tree. As the baffles 10 move, the rotating plate 22 rotates under the push of the tree. At the same time, under the action of the counterweight 30, the rotating plate 22 always sticks to the tree. After the two sets of baffles 10 contact, the two sets of tracks 11 form a complete circle, and the two sets of incomplete end face toothed rings 12 form a complete end face toothed ring. At this time, the straight section of the rotating plate 22 near the slider 21 is tangent to the tree surface, so that the vertical plane of the first sand blowing pipe 23 is tangent to the tree surface. At this time, the motor 25 drives the gear 26 to rotate, and the blower 27 delivers air into the first sand-blowing pipe 23. Under the action of the gear 26 and the incomplete end face gear ring 12, the slider 21 moves on the track 11. The slider 21 rotates around the tree. After the air is blown out from the first sand-blowing pipe 23, it blows towards the sand at the base of the tree. The air blows away the sand near the base of the tree. The baffle 10 prevents the blown sand from splashing randomly. After the slider 21 rotates one revolution, the sand near the base of the tree is blown away and accumulates inside the baffle 10. A small ring-shaped groove appears around the base of the tree. At this time, water is sprayed into the groove through the water spray pipe 14. After the spraying is completed, the slider 21 moves one revolution in the opposite direction. When it moves in the opposite direction, the blower 27 delivers air into the second sand-blowing pipe 24. After the air is blown out, it interacts with the baffle 10. The air then flows towards the tree roots, blowing the sand accumulated on the inner side of the baffle 10 towards the tree roots to backfill the small trenches around the tree roots. After backfilling, the tree is irrigated. The air blown out by the first sand blowing pipe 23 cleans the sand around the tree roots, creating a ring-shaped trench around the tree roots. Water is then sprayed into the trench through the water spray pipe 14, increasing the irrigation depth and avoiding damage to the tree roots. This reduces water evaporation, which is beneficial for the tree's subsequent absorption and reduces water consumption. After irrigation, the air blown out by the second sand blowing pipe 24 backfills and covers the irrigated area with sand, burying the damp sand and water underneath, further reducing water evaporation and improving the equipment's water-saving capacity.

[0033] like Figures 2-6 As shown, this invention provides a water-saving sprinkler irrigation device for greening Gobi Desert. A base plate 33 is fixedly installed at the end of the baffle 10. A U-shaped closed frame 16 is slidably installed on the base plate 33 via a mounting bracket 15. An elastic membrane 17 is fixedly installed inside the closed frame 16. A second electric telescopic rod 18 that drives the closed frame 16 to move is fixedly installed on the baffle 10. The two sets of closed frames 16 are of different sizes and the elastic membranes 17 on the two sets of closed frames 16 are of different heights. When the two sets of closed frames 16 come into contact, their parallel section sidewalls slide in contact.

[0034] Specifically, one of the elastic membranes 17 has a protrusion 19 at one end away from the second electric telescopic rod 18. Both ends of the protrusion 19 are fixedly connected to support rods 20 that are slidably mounted on the closed frame 16. The support rods 20 are used in conjunction with the limiting push plate 32 that is fixedly mounted on another set of base plates 33.

[0035] In practical application, after the two sets of baffles 10 come into contact, the second electric telescopic rod 18 drives one set of enclosure frames 16 to move. As the enclosure frames 16 move, the two sets of enclosure frames 16 come into contact, and one set of enclosure frames 16 enters the other set of enclosure frames 16. When the enclosure frames 16 move, the elastic membrane 17 will come into contact with the tree surface. At this time, the enclosure frames 16 continue to move, and the elastic membrane 17 will form a conical opening. The two sets of elastic membranes 17 surround the conical opening formed around the tree, so that the elastic membrane 17 can block most of the area of ​​the area blocked by the baffles 10. At this time, there is a gap at the position where the elastic membranes 17 on both sides of the tree intersect. As the enclosure frame 16 moves, the support rod 2 The support rod 20 moves inward and stretches the protrusion 19 under the action of the limit push plate 32, thereby gradually reducing the opening of the elastic membrane 17 at the contact point with the tree. The protrusion 19 can then block the gap at the intersection of the elastic membranes 17 on both sides of the tree, thus achieving complete blocking of the area enclosed by the baffle 10. Subsequently, soil turning and irrigation operations can be carried out. The elastic membrane 17 and the baffle 10 cooperate to form a closed area, preventing sand from flying outward during sand blowing, ensuring sufficient backfill sand, and reducing air contact with the irrigation position, further reducing the water evaporation rate and further improving the water-saving effect of the equipment.
