Description

Technical Field

[0001] This utility model relates to the technical field of municipal landscaping spraying devices, and more specifically, it relates to a special spraying device for municipal landscaping diseases. Background Technology

[0002] In the maintenance of municipal landscaping and greening, systematic measures must be implemented according to the tree's growth cycle to prevent pests and diseases. This includes regular inspections, scientific pruning, removal of sources of disease, and timely intervention using physical, biological, and environmentally friendly pesticides to effectively control the occurrence and spread of pests and diseases, ensuring the healthy and robust growth of trees.

[0003] The following problems still exist when spraying pesticides on municipal parks and green spaces: Currently, in municipal landscaping disease control operations, the application of pesticides to diseased plants generally relies on manual methods. Specifically, maintenance workers typically carry heavy sprayers or powered spraying devices on their backs, moving on foot to spray the target plants. However, when dealing with large areas of linearly distributed rows of greenery in landscaping, this method reveals significant shortcomings: due to the limited amount of pesticide carried per application and the narrow spray coverage area, workers must frequently travel between the preparation point and the application point to replenish the pesticide. This intermittent workflow severely disrupts the continuity of spraying, directly leading to low overall operational efficiency. Furthermore, controlling the spatial distance between the nozzle and the plant leaves during spraying is a crucial factor affecting the effectiveness and cost-effectiveness of the pesticide application. If the nozzle is placed too close to the plant, the pesticide will not be able to fully atomize and diffuse due to insufficient space, resulting in a significantly reduced coverage area and the possibility of pesticide accumulation in some areas while other parts remain uncovered. Conversely, if the nozzle distance is adjusted too far, some of the atomized liquid will not be able to effectively adhere to the plant surface, but will instead drift into the air with the wind. This not only results in a direct waste of the liquid and increases maintenance costs, but may also lead to unnecessary air pollution and environmental risks.

[0004] In view of this, we propose a special spraying device for municipal garden diseases. Utility Model Content

[0006] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: a special spraying device for municipal landscaping diseases, comprising a crossbeam, a hook fixedly connected to the upper end of the crossbeam, a groove provided on the lower side of the crossbeam, two sliders slidably connected in the groove of the crossbeam, two spline sleeves rotatably connected to the sliders, a spline rod rotatably connected to the lower side of the crossbeam, the spline rod passing through the spline sleeve, a rotating component splinedly connected to the spline rod, a vertical rod fixedly connected to the rotating component, a horizontal rod hinged to the vertical rod, the two vertical rods not being on the same plane, a flexible hose fixedly connected between the horizontal rod and the vertical rod, nozzles evenly spaced installed on the flexible hose, and an adjustment structure provided on the upper side of the crossbeam.

[0007] The present invention is further configured such that the rotating member is located between two adjacent spline sleeves.

[0008] The present invention is further configured such that the crossbeam has symmetrically distributed through grooves, and the through grooves are connected to the sliding grooves of the crossbeam.

[0009] The present invention is further configured such that the adjustment structure includes two threaded sleeves, the two threaded sleeves are respectively fixed to the two sliders, the threaded sleeves slide within the through groove, and the crossbeam is fixed to a double-headed motor.

[0011] The present invention is further configured such that the threaded rod passes through the adjacent threaded sleeve, and the threaded rod is threadedly connected to the adjacent threaded sleeve.

[0012] The present invention is further configured such that the helical directions of the thread grooves of the two threaded rods are opposite.

[0014] (III) Beneficial Effects Compared with the prior art, this utility model provides a special spraying device for municipal landscaping diseases, which has the following beneficial effects: 1. This utility model, through the ingenious design of horizontal beams, vertical poles, and crossbars, can form a three-dimensional spraying network on both sides and top of green plants. During operation, the device is towed by a vehicle and passes through in one go, achieving simultaneous pesticide coverage on all facades of a row of green plants. This changes the traditional manual back-and-forth operation mode, reduces repetitive labor and operation time, and improves spraying efficiency.

[0015] 2. This invention uses a dual-head motor to drive a threaded rod, controlling the distance between the two vertical rods to ensure the nozzle is always at the optimal spraying distance. This solves the problems of uneven coverage due to too close a distance or spraying of the pesticide due to too far a distance, ensuring that most of the pesticide adheres precisely to the plant surface, thereby reducing pesticide waste and lowering maintenance costs and environmental pollution.

[0016] 3. This utility model has multi-degree-of-freedom adjustment capabilities. Drive motor one can drive the spline rod to make the vertical rod swing as a whole to adapt to greenery of different heights; drive motor two can adjust the angle of the horizontal rod to adapt to irregular contour shapes, thus improving the versatility and work efficiency of the equipment.

A groove is provided on the lower side of the crossbeam 1, and two sliders 3 are slidably connected in the groove of the crossbeam 1. Two spline sleeves 4 are rotatably connected to the sliders 3. A spline rod 5 is rotatably connected to the lower side of the crossbeam 1, and the spline rod 5 passes through the spline sleeve 4. A rotating part 6 is splinedly connected to the spline rod 5. A vertical rod 7 is fixedly connected to the rotating part 6, and a horizontal rod 8 is hinged to the vertical rod 7. The two vertical rods 7 are not on the same plane. A flexible hose 9 is fixedly connected between the horizontal rod 8 and the vertical rod 7. The flexible hose 9 is equipped with nozzles 10 that are evenly distributed. An adjustment structure is provided on the upper side of the crossbeam 1. The rotating part 6 is located between two adjacent spline sleeves 4. The crossbeam 1 has symmetrically distributed through grooves 11, which are connected to the groove of the crossbeam 1.

[0023] Please see Figures 3-5 The adjustment structure includes two threaded sleeves 12, which are respectively fixed to two sliders 3. The threaded sleeves 12 slide within the through groove 11. A crossbeam 1 is fixed to a double-headed motor 13. Two support plates 14 are fixed to the crossbeam 1. The output shaft of the double-headed motor 13 is fixed to a threaded rod 15, which is rotatably connected to the adjacent support plate 14. The threaded rod 15 passes through the adjacent threaded sleeve 12 and is threadedly connected to the adjacent threaded sleeve 12. The spiral directions of the thread grooves of the two threaded rods 15 are opposite. A fixing member 16 is fixed to the crossbeam 1. A drive motor 17 is fixed to the fixing member 16. The output shaft of the drive motor 17 is fixed to the splined rod 5. A drive motor 18 is fixed to the vertical rod 7. The output shaft of the drive motor 18 is fixed to the adjacent horizontal rod 8.

[0024] The working principle of this utility model: When using the spraying device, first install the hook 2 on the drive vehicle and connect the two hoses 9 to the spraying pipeline. During use, position the two vertical poles 7 on the left and right sides of the row of green plants respectively. Then, adjust the distance between the two vertical poles 7 according to the width of the row of green plants. The specific adjustment method is as follows: Start the dual-head motor 13. Both output shafts of the dual-head motor 13 drive the threaded rod 15 on them to rotate. The threaded rod 15 drives the threaded sleeve 12 to move through the thread. The threaded sleeve 12 drives the slider 3 to move along the crossbeam 1, thereby adjusting the distance between the two vertical rods 7. This adjusts the distance between the nozzle 10 and the row of green plants, preventing the nozzle 10 from being too far away from the row of green plants, which would cause some of the liquid to be sprayed into the air and waste some of the liquid.

[0025] After the spacing between the two vertical rods 7 is adjusted, turn off the dual-head motor 13. Then, adjust the angle of the two horizontal rods 8 according to the shape of the row of green plants. In the initial state, the horizontal rods 8 are perpendicular to the adjacent vertical rods 7. If the middle of the row of green plants protrudes upward, start the two drive motors to change the angle between the horizontal rods 8 and the vertical rods 7, so that the spraying device can adapt to rows of green plants of different shapes.

[0026] Then, the pesticide solution is pumped into the hose 9, and then atomized and sprayed out from the nozzle 10 to spray the rows of green plants. When it is necessary to adjust according to the height of the rows of green plants, the drive motor 1 is started. The output shaft of the drive motor 17 drives the spline rod 5 to rotate. The spline rod 5 drives the rotating part 6 to rotate, and at the same time, the spline sleeve 4 rotates along the slider 3. The spline sleeve 4 drives the vertical rod 7 to swing, so that the vertical rod 7 changes to an inclined state, thereby adapting to rows of green plants of different heights. Then, the drive vehicle is started and moves along the rows of green plants, thereby achieving simultaneous spraying of the sides and top of the rows of green plants, providing high spraying efficiency.
