Description

Technical Field

[0001] The invention relates to the technical field of irrigation, in particular to an irrigation dripper for poplar planting in arid areas. Background Art

[0002] Annual precipitation in arid areas is usually low, and groundwater resources are relatively scarce. In such an environment, how to efficiently use limited water resources to ensure the growth of poplars becomes a key issue. As a fast-growing tree species, poplars have certain requirements for water during their growth. Especially in the peak growing season, water shortage will seriously affect their growth rate and wood quality. Poplar planting in arid areas faces severe challenges of water shortage. Traditional irrigation methods, such as flooding, often lead to a large waste of water resources, and the water distribution is uneven, which is difficult to meet the needs of poplar growth. In order to solve the above problems, drip irrigation technology has gradually attracted attention. Drip irrigation can deliver water drop by drop directly to the soil near the roots of poplars, greatly improving the utilization rate of water.

[0003] When the existing device uses the irrigation device to drip irrigate the tree trunks, it is impossible to adjust the distance between multiple groups of irrigation devices according to the spacing between the tree trunks, and it is impossible to accurately drip irrigate multiple tree trunks at the same time, and the irrigation efficiency is low.

Two groups of air vents 64 are opened, and the two groups of air vents 64 are symmetrically distributed on the sides of the arc-shaped protective cover 61. Two groups of arc-shaped protective covers 61 are provided, and the two groups of arc-shaped protective covers 61 are symmetrically distributed. The side of the dripping device 66 is fixedly connected to the inner side of the arc-shaped protective cover 61 through a bracket.

[0045] The irrigation device 6 further includes a protection device 67 , one side of which is fixedly connected to the outer side of the arc-shaped protection cover 61 .

[0046] The protective device 67 includes an electric slide rail 671, the interior of the electric slide rail 671 is slidably connected to an elastic telescopic rod 672 through an electric slider, the end of the elastic telescopic rod 672 is rotatably connected to a sliding frame 674 through a rotating seat 673, the inner side of the sliding frame 674 is fixedly connected to a pulling roller 675 through a bracket, the outer side of the pulling roller 675 is fixedly connected to a sealing cloth 676, the side of the sealing cloth 676 away from the pulling roller 675 is fixedly connected to a winding roller 677, both ends of the winding roller 677 are rotatably connected to a positioning frame 678 through rolling bearings, the outer side of the arc-shaped protective cover 61 is fixedly connected to a limiting slide rail 679 through a bracket, and the inner wall of the limiting slide rail 679 is slidably connected to a limiting slider 6710.

[0047] One side of the electric slide rail 671 is fixedly connected to the outer side of the arc-shaped protective cover 61, the sealing cloth 676 is wound on the winding roller 677, one side of the positioning frame 678 is fixedly connected to the outer side of the arc-shaped protective cover 61, and springs are installed between both ends of the winding roller 677 and the positioning frame 678.

[0048] The side of the limiting slider 6710 away from the limiting slide rail 679 is fixedly connected to the side of the sliding frame 674. There are two groups of limiting slide rails 679, and the two groups of limiting slide rails 679 are symmetrically distributed on both sides of the sliding frame 674. Both ends of the pulling roller 675 are fixedly connected to the inner side of the sliding frame 674 through the bracket.

[0049] During use, the operator puts the two sets of arc-shaped protective covers 61 on the tree trunk in turn, and then uses the bolt and nut assembly 65 to lock the two sets of arc-shaped protective covers 61 together, so that the two sets of arc-shaped protective covers 61 can be fixed on the outer side of the tree trunk close to the ground, so that the bottom of the arc-shaped protective covers 61 contacts the ground, and then injects water, fertilizer or medicine into the drainage pipe 3 through the water inlet pipe 4. The water enters the water delivery pipe 1 from the drainage pipe 3 through the first corrugated pipe 2, and then drips onto the ground near the tree trunk through the dripping device 66, so that the root system of the tree trunk can be drip-irrigated. Since there are multiple sets of irrigation devices 6, the arc-shaped protective covers 61 in the irrigation device 6 can be put on the trunks of multiple poplar trees in turn, and the first corrugated pipe 2 can be lengthened or shortened by moving the drainage pipe 3, so that the distance between the multiple sets of irrigation devices 6 can be adjusted according to the spacing between the trunks, so that multiple tree trunks can be drip-irrigated accurately.

[0050] When the drip device 66 is used for drip irrigation of the root system of the tree trunk, the electric slide rail 671 is turned on, and the electric slider inside the electric slide rail 671 is used to drive the elastic telescopic rod 672 to slide down. During the sliding process of the elastic telescopic rod 672, the rotating seat 673 is driven to squeeze the sliding frame 674. The sliding frame 674 slides inside the limiting slide rail 679 through the limiting slider 6710 and drives the pulling roller 675 to move. During the movement of the pulling roller 675, the sealing cloth 676 is pulled, so that the sealing cloth 676 drives the winding roller 677 to rotate and release the wound sealing cloth 676. As the sealing cloth 676 is pulled out by the pulling roller 675, the pulled sealing cloth 676 covers the air vent 64, and blocks the air vent 64 during drip irrigation, thereby reducing the influence of the surrounding air flow on water evaporation and preventing the dripping water from evaporating too quickly.

[0051] After a period of time after the drip irrigation ends, the electric slide rail 671 is turned on again, and the electric slider inside the electric slide rail 671 drives the elastic telescopic rod 672 to slide up, and the sliding frame 674 slides upward. At this time, the winding roller 677 rotates in the opposite direction through the resilience of the springs at both ends and winds up the sealing cloth 676. As the sliding frame 674 continues to slide upward, the sealing cloth 676 is wound on the winding roller 677 and no longer covers the air vent 64. The air vent 64 can be opened in time to ensure that the roots at the trunk can be ventilated.

[0052] For the second embodiment, please refer to Figure 1-Figure 9 The present invention provides a technical solution: on the basis of the first embodiment, the dripping device 66 includes an arc-shaped limit sliding frame 661, a threaded clamping hole 662 is opened on one side of the arc-shaped limit sliding frame 661, a movable plate 663 is slidably connected to the inner wall of the arc-shaped limit sliding frame 661, a threaded rotating rod 664 is penetrated and threadedly connected to one side of the movable plate 663, a water outlet pipe 665 is penetrated and fixedly connected to the top of the movable plate 663, a dripper 666 is connected to the bottom of the water outlet pipe 665, and one end of the water outlet pipe 665 away from the dripper 666 is connected to a water delivery tray 667, and a plurality of water delivery trays 667 are provided, and the plurality of water delivery trays 667 are connected through a second corrugated pipe 668.

[0053] Both sides of the arc-shaped limiting sliding frame 661 are fixedly connected to the inner side of the arc-shaped protective cover 61 through a bracket, and multiple groups of threaded holes 662 are provided, and the multiple groups of threaded holes 662 are evenly distributed on the sides of the arc-shaped limiting sliding frame 661, and the threaded rotating rod 664 passes through the threaded holes 662 and is threadedly connected to the threaded holes 662.

[0054] The movable plates 663 are provided in multiple groups and correspond one to one with the water delivery trays 667 , and the top of the water delivery tray 667 is connected to the bottom of the rubber tube 5 .

[0055] When in use, water enters the water delivery tray 667 from the rubber tube 5, and then enters the water outlet pipe 665 through the water delivery tray 667, and finally drips into the root system of the tree trunk through the dripper 666. Before drip irrigation, the threaded rotating rod 664 is manually rotated to rotate the threaded rotating rod 664 out of the movable plate 663 and the threaded clamping hole 662, and then the water outlet pipe 665 is moved, and the water outlet pipe 665 drives the movable plate 663 to slide inside the arc-shaped limit sliding frame 661. At the same time, the water outlet pipe 665 drives the water delivery tray 667 to stretch the second corrugated pipe 668, and slides the water outlet pipe 665 to the area corresponding to the threaded clamping hole 662, and then rotates into the threaded clamping hole 662 and then into the movable plate 663 through the threaded rotating rod 664, so that the movable plate 663 can be fixed in the arc-shaped limit sliding frame 661. Since there are multiple groups of threaded clamping holes 662, the position and range of dripping can be flexibly adjusted to improve irrigation efficiency and coverage.

[0056] Working process: the operator puts two sets of arc-shaped protective covers 61 on the tree trunk in turn, and then uses the bolt and nut assembly 65 to lock the two sets of arc-shaped protective covers 61 together, so that the two sets of arc-shaped protective covers 61 can be fixed on the outer side of the tree trunk close to the ground, so that the bottom of the arc-shaped protective covers 61 is in contact with the ground, and then water, fertilizer or medicine is injected into the drainage pipe 3 through the water inlet pipe 4. The water enters the water delivery pipe 1 from the drainage pipe 3 through the first corrugated pipe 2, and then drips on the ground near the tree trunk through the drip device 66, so that the root system of the tree trunk can be drip-irrigated. Since the irrigation device 6 is provided with multiple groups, the arc-shaped protective covers 61 in the irrigation device 6 can be put on the trunks of multiple poplar trees in turn, and the first corrugated pipe 2 is driven by the moving drainage pipe 3. The bellows 2 can be lengthened or shortened to adjust the distance between the multiple irrigation devices 6 according to the spacing between the tree trunks. When the drip device 66 is used to drip irrigate the root system of the tree trunk, the electric slide rail 671 is turned on, and the electric slider inside the electric slide rail 671 is used to drive the elastic telescopic rod 672 to slide down. During the sliding process of the elastic telescopic rod 672, the rotating seat 673 is driven to squeeze the sliding frame 674. The sliding frame 674 slides inside the limiting slide rail 679 through the limiting slider 6710 and drives the pulling roller 675 to move. During the movement of the pulling roller 675, the sealing cloth 676 is pulled, so that the sealing cloth 676 drives the winding roller 677 to rotate and release the wound sealing cloth 676. As the sealing cloth 676 is pulled by the pulling roller 67 5 is pulled out, and the pulled out sealing cloth 676 covers the vent 64, blocking the vent 64 during drip irrigation. After a period of time after the drip irrigation ends, the electric slide rail 671 is turned on again, and the electric slider inside the electric slide rail 671 drives the elastic telescopic rod 672 to slide up, and the sliding frame 674 slides upward. At this time, the winding roller 677 rotates in the opposite direction through the resilience of the springs at both ends and winds up the rolled sealing cloth 676. As the sliding frame 674 slides upward continuously, the sealing cloth 676 is wound on the winding roller 677 and no longer covers the vent 64, so the vent 64 can be opened in time, and water enters the water delivery tray 667 from the rubber tube 5, and then enters the inside of the water outlet pipe 665 through the water delivery tray 667, and finally passes through the dripper 66. 6 drips into the root system of the tree trunk. Before drip irrigation, manually rotate the threaded rotating rod 664 to rotate the threaded rotating rod 664 out of the movable plate 663 and the threaded clamping hole 662, and then move the water outlet pipe 665. The water outlet pipe 665 drives the movable plate 663 to slide inside the arc-shaped limit sliding frame 661. At the same time, the water outlet pipe 665 drives the water delivery tray 667 to stretch the second corrugated pipe 668, and slides the water outlet pipe 665 to the area corresponding to the threaded clamping hole 662. Then, the threaded rotating rod 664 is rotated into the threaded clamping hole 662 and then into the movable plate 663, so that the movable plate 663 can be fixed in the arc-shaped limit sliding frame 661. Since there are multiple groups of threaded clamping holes 662, the position and range of dripping can be flexibly adjusted.

[0057] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention.
