Description

Technical Field

[0001] The invention belongs to the technical field of three-dimensional greening sprinkler irrigation and fertilization, and in particular relates to a three-dimensional greening sprinkler irrigation system with timed spraying. Background Art

[0002] Three-dimensional greening refers to a greening method that makes full use of different site conditions, selects climbing plants and other plants to plant and attach or lay them on various structures and other spatial structures, including overpasses, building walls, slopes, river embankments, roofs, gates, flower stands, trellises, balconies, corridors, columns, fences, dead trees and various rockery and architectural facilities. During the growth and maintenance process of three-dimensional greening, it is necessary to fertilize it regularly to supplement the nutrients needed by the vegetation in the three-dimensional greening.

[0003] The shapes of buildings climbed or planted by three-dimensional greening vary. The most common ones are planted or climbed on the outside of the building, perpendicular to the ground. However, in actual situations, there are also irregular buildings with vegetation planted or climbing on their surfaces, adjacent ground and roofs, making it difficult to sprinkle irrigation and fertilize.

[0004] In the Chinese patent with publication number CN105191561A, a three-dimensional greening sprinkler system with timed spraying is mentioned. The three-dimensional greening sprinkler system with timed spraying can automatically control the spraying of plants, reduce the artificial maintenance cost of three-dimensional greening, reduce the construction difficulty of artistic modeling, realize the rapid expansion of wall area, prevent the breeding of mosquito electric bacteria, realize the proportional circulation supply of nutrients required by greening plants, and reduce the artificial maintenance link of fertilization;

[0005] The existing three-dimensional greening sprinkler irrigation and fertilization can only be carried out on the three-dimensional greening on one side of the building. When it is necessary to fertilize the greening on the ground adjacent to the building, the sprinkler irrigation and fertilization equipment needs to be moved to achieve it, which is inconvenient to operate.

[0049] The mounting plate 513 is located at the bottom of the vertical threaded rod 514;

[0050] The connecting groove 536 is connected to a middle group of fertilizer nozzles 533;

[0051] The moving plate 527 is in contact with the inner front side of the housing 523 .

[0052] In a further embodiment, referring to Figure 1-Figure 5 A slide groove 512 is provided on the inner side of the spray rack 5, and the slide groove 512 limits the moving trajectory of the slider 515 to ensure that the slider 515 can only move in the up and down directions. A slider 515 is fixedly connected to the rear side of the mounting plate 513, and the slider 515 is slidably connected to the inner side of the slide groove 512. The moving trajectory of the mounting plate 513 is limited under the cooperation of the slider 515 and the slide groove 512 to ensure that the mounting plate 513 can only move in the up and down directions, and the position of the mounting plate 513 is limited so that it will not be offset or tilted when in use.

The vertical threaded rod 514 is movably connected to the top of the base 1 through a bearing, and the vertical threaded rod 514 can rotate in the spray rack 5 under the action of the bearing.

[0053] In this embodiment, the driving motor 511 drives the vertical threaded rod 514 to rotate through the output shaft, thereby adjusting the height of the mounting plate 513 and the angle adjustment component 52 installed outside the mounting plate 513 and some components of the sprinkler irrigation and fertilization, so as to facilitate the fertilization and sprinkler irrigation of the three-dimensional greening outside the building.

[0054] In a further embodiment, referring to Figure 3-Figure 5A stepper motor 529 is fixedly connected to the outside of the shell 523, and the stepper motor 529 is fixedly connected to a transverse threaded rod 526 through an output shaft. The stepper motor 529 can drive the transverse threaded rod 526 to rotate through the output shaft. The rear end of the transverse threaded rod 526 passes through the front side of the shell 523 and is movably connected to the front side of the shell 523 through a bearing. The inner rear side of the shell 523 is movably connected to the rear end of the transverse threaded rod 526 through a bearing. The movable plate 527 is threadedly connected to the outside of the transverse threaded rod 526. The transverse threaded rod 526 rotates the movable plate 527 to move horizontally forward and backward, driving the fixed plate 522 and the sprinkler irrigation and fertilization assembly 53 fixed on the outside of the fixed plate 522 to move. The outer side of the movable plate 527 is fixedly connected to a limiting block 528.

[0055] Specifically, a limiting groove is provided on the inner side of the shell 523 , and the limiting block 528 is slidably connected to the inner side of the limiting groove. The limiting groove and the limiting block 528 limit the moving track of the moving plate 527 .

[0056] In this embodiment, the stepper motor 529 drives the transverse threaded rod 526 to rotate through the output shaft, so as to horizontally move the fixed plate 522 and some components of the sprinkler fertilization assembly 53 fixed outside the fixed plate 522, thereby cooperating with the three-dimensional greening at different positions on the ground and on the top of the building for fertilization and irrigation.

[0057] In a further embodiment, referring to Figure 3-Figure 6 The servo motor 524 is fixedly connected to a motor frame 521 on the outside, and the motor frame 521 is fixedly connected to the outside of the fixed plate 522. The motor frame 521 is used to connect the servo motor 524 and the fixed plate 522. The servo motor 524 is fixedly connected to a driving gear 525 through an output shaft. The servo motor 524 can drive the driving gear 525 to rotate through the output shaft. The outer side of the inner hollow rod 531 is fixedly connected to a driven gear. The rotation of the driven gear can drive the inner hollow rod 531 to rotate. The outer side of the driving gear 525 is meshed with the outer side of the driven gear. The driving gear 525 drives the inner hollow rod 531 through the driven gear. The rod 531 rotates to adjust the position of the connecting groove 536. A circular hole 5210 is opened in the middle of the fixed plate 522. The circular hole 5210 is used for installing the inner hollow rod 531. The inner hollow rod 531 is movably connected to the inner side of the circular hole 5210 through a bearing. Under the action of the bearing, the inner hollow rod 531 can rotate on the fixed plate 522. The outer side of the outer tube 532 is fixedly connected to the limiting frame 534. The limiting frame 534 is used to fix the position of the outer tube 532 and fix it on the outer side of the fixed plate 522. The limiting frame 534 is fixedly connected to the outer side of the fixed plate 522 to ensure the stability of the outer tube 532 during operation.

[0058] In this embodiment, the servo motor 524 can adjust the position of the inner hollow rod 531 inside the outer tube 532 through the driving gear 525 and the driven gear, thereby changing the position of the connecting groove 536, so that the fertilizer nozzles 533 at different positions can work, thereby fertilizing and irrigating the three-dimensional greening at different positions outside the building.

[0059] In a further embodiment, referring to Figure 3 and Figure 6-Figure 8 The outer side of the inner hollow rod 531 is provided with a connecting groove 536 connected to the inner side of the inner hollow rod 531. The connecting groove 536 is used to allow the liquid fertilizer in the inner hollow rod 531 to enter each fertilizer nozzle 533. The outer side of the inner hollow rod 531 is adapted to the inner side of the outer tube 532. In actual use, the liquid fertilizer will not flow out from the gap between the inner hollow rod 531 and the outer tube 532. However, when in use, the inner hollow rod 531 can rotate in the outer tube 532, and the fertilizer nozzle 533 is close to the outer tube 532. One end of the tube 532 is connected to the interior of the outer tube 532, a booster pump 537 is fixedly connected to the top of the liquid fertilizer tank 2, a water outlet of the booster pump 537 is fixedly connected to a water inlet pipe 535, the other end of the water inlet pipe 535 passes through the outside of the inner hollow rod 531 and is connected to the interior of the inner hollow rod 531, a water inlet of the booster pump 537 is fixedly connected to a water pumping pipe 538, a water pump 539 is provided at the other end of the water pumping pipe 538, and the water pump 539 is fixedly connected to the inside of the liquid fertilizer tank 2.

[0060] Specifically, both ends of the water inlet pipe 535 are configured to be retractable to facilitate the movement of the inner hollow rod 531 and avoid damage to the water inlet pipe 535. A fixing ring is fixedly connected to the middle outer side of the water inlet pipe 535, and the fixing ring is fixedly connected to the top of the mounting plate 513 for moving up and down with the mounting plate 513.

[0061] Specifically, the boost pump 537 can be divided into three gears of high, medium and low during actual use. When performing sprinkler irrigation and fertilization for three-dimensional greening outside a building, the medium boost gear is used. When performing spray fertilization for three-dimensional greening on the ground adjacent to the outside of the building, the low boost gear is used. When performing sprinkler irrigation and fertilization for three-dimensional greening on the top of the building, the high gear is used.

[0062] In this embodiment, when the inner hollow rod 531 rotates, the position of the connecting groove 536 opened on its surface changes, so that the liquid fertilizer can enter the fertilizer nozzle 533 at different positions, fertilize and irrigate the three-dimensional greening at different positions, improve the efficiency of fertilization and irrigation, and reduce the difficulty of fertilization and irrigation.

[0063] It should be noted that the connection between the above-mentioned single chip microcomputer and the timer and other devices belongs to the prior art and is well known in the art, so it will not be described in detail here.

[0064] The working principle of the present invention is as follows:

[0065] The device is moved to the three-dimensional greening outside the building by the brake wheel 4;

[0066] According to the information of the three-dimensional greening outside the building, the time for regular sprinkler irrigation and fertilization is set through the timer in the controller box 3;

[0067] When the three-dimensional greening outside the building is sprinkled with fertilizer, the agent enters the liquid fertilizer box 2 and is stirred by the stirring member 22 to ensure that the fertilizer agent and water are fully mixed. After fully mixed, the water pump 539 extracts the liquid fertilizer in the liquid fertilizer box 2 through the suction pipe 538, the booster pump 537 and the water inlet pipe 535 into the inner hollow rod 531. The liquid fertilizer in the inner hollow rod 531 enters each fertilizer nozzle 533 located in the middle through the connecting groove 536, and is sprayed out through the fertilizer nozzle 533 to sprinkle the three-dimensional greening outside the building. At the same time, the driving motor 511 drives the vertical threaded rod 514 to rotate, so that the height of the fertilizer nozzle 533 is adjusted through the mounting plate 513, so that the three-dimensional greening on the entire outside of the building is evenly fertilized;

[0068] When the three-dimensional greening fertilizer application outside the building is completed, the driving motor 511 adjusts the fertilizer nozzle 533 to the lowest position, and the servo motor 524 drives the driving gear 525 to rotate through the output shaft, and the driving gear 525 rotates to drive the driven gear to rotate, thereby driving the inner hollow rod 531 to rotate, and rotating the connecting groove 536 to the nozzle at the bottom of the outer tube 532. At this time, the fertilizer nozzle 533 at the bottom of the outer tube 532 works. At the same time, the stepping motor 529 drives the horizontal threaded rod 526 to rotate, and drives the fertilizer nozzle 533 to move horizontally, so as to sprinkle and fertilize the three-dimensional greening on the ground adjacent to the outside of the building;

[0069] When the three-dimensional greening on the ground adjacent to the outside of the building is sprinkled and fertilized, the driving motor 511 adjusts the outer tube 532 to the highest position, and the servo motor 524 adjusts the connecting groove 536 on the outside of the inner hollow rod 531 to the fertilizer nozzle 533 at the upper position of the outside of the outer tube 532 through the driving gear 525 and the driven gear. The liquid fertilizer is sprinkled and fertilized on the three-dimensional greening on the top of the building through the inclined fertilizer nozzle 533. The stepper motor 529 adjusts the position of the outer tube 532 through the transverse threaded rod 526, and cooperates with the booster pump 537 to increase the pressure of the liquid fertilizer, so as to evenly fertilize the three-dimensional greening at different positions on the top of the building.

[0070] When the vertical greening outside the building, on the ground adjacent to the outside of the building and on the top of the building has been fertilized, the equipment is reset to facilitate the next fertilization cycle, and the vertical greening outside the building is fertilized again.

[0071] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
