Description
Technical Field
[0001] This utility model relates to the field of irrigation equipment technology, and in particular to a pre-embedded garden maintenance spraying device. Background Technology
[0002] A garden is a beautiful natural environment and recreational space created by using engineering techniques and artistic methods within a specific area. This involves modifying the terrain (or further constructing mountains, stacking rocks, and managing water), planting trees and flowers, constructing buildings, and arranging garden paths. Modern lifestyles and living environments place urgent functional and artistic demands on gardens. They play an increasingly important role in our modern lives and the future development of our people. A lawn is an artificial grassland made of densely planted, mowed perennial, low-growing herbaceous plants.
[0003] Chinese utility model patent CN222898130U discloses a pre-embedded garden maintenance spray device, including a storage box. A guide groove is fixedly installed at the bottom inside the storage box. A drive motor located on one side of the guide rail is fixedly installed at the bottom inside the storage box. Vertical rails are fixedly installed at the four corners inside the storage box. Horizontal rails are fixedly installed on the front and rear sides of the top of the storage box. A bidirectional lead screw is rotatably connected inside the guide groove. One end of the bidirectional lead screw is connected to the output end of the drive motor. A moving block is threaded through the bidirectional lead screw. A connecting rod is rotatably connected through the top of the moving block. Right-angle brackets are fixedly installed at both ends of the connecting rod. A lifting plate is rotatably connected to the top of one end of the right-angle bracket. A nozzle is provided on the top of the lifting plate. A push rod is rotatably connected through the top of the other end of the right-angle bracket. Both ends of the push rod are connected to the vertical rails. A fixed crossbar is rotatably connected through both ends of the push rod. A closed cover is fixedly installed on the top of the fixed crossbar. A sliding block is rotatably connected to the other end of the fixed crossbar. The sliding block is slidably connected to the horizontal rail. The drive motor drives two bidirectional lead screws to rotate, causing the moving block to move closer to the center of the guide groove. This causes the connecting rod to rotate the right-angle bracket, lifting the lifting plate. At the same time, the other end of the right-angle bracket drives the push rod to move down along the vertical slide rail and pulls one end of the fixed crossbar down. The other end of the fixed crossbar moves along the horizontal slide rail to both sides of the storage box, opening the closed cover.
[0004] Regarding the aforementioned technologies, the inventors believe that the following defects exist: During the opening process of the aforementioned device, the sealing cover moves to both sides inside the storage box. This action causes dust and dirt particles adhering to the surface of the cover due to wind or rain splashes to enter the storage box. If they adhere to the thread gap of the bidirectional lead screw, they will increase the frictional resistance between the lead screw and the moving block, leading to transmission jamming or even a decrease in accuracy. If they accumulate in the guide groove, vertical slide rail, or horizontal slide rail, they will hinder the smooth sliding of the sliding block and adversely affect the operation of the internal components. Utility Model Content
[0005] To address the aforementioned problems, this utility model provides a pre-embedded garden maintenance spraying device.
[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a pre-embedded garden maintenance spraying device, including an installation box, a riser pipe connected to the top of the installation box, a vertically sliding lifting plate inside the installation box, a lifting assembly for driving the lifting plate to rise and fall inside the installation box, a spray seat on the lifting plate, a column vertically arranged on the top surface of the spray seat, a connecting plate at the upper end of the column, a plurality of circumferentially spaced sliding holes on the connecting plate, a sliding rod slidably arranged in the sliding holes, a connecting ring at the lower end of the plurality of sliding rods, and a circular top cover at the upper end of the plurality of sliding rods, the diameter of the top cover being the same as the outer diameter of the column, and a spring sleeved on the rod body located between the connecting ring and the connecting plate.
[0007] By adopting the above technical solution, an installation box, riser, lifting assembly, and spray base are installed. The lifting assembly drives the lifting plate to rise and fall, which in turn moves the spray base, column, and connecting plate synchronously. This allows the spray base to extend in the working state and retract in the non-working state, meeting the concealment requirements of pre-embedded equipment and reducing interference with the landscape. When the lifting plate lowers the lifting plate, spray base, column, and top cover until the top cover contacts the column, the distance between the connecting plate and connecting ring decreases as the lifting plate continues to descend. The spring is compressed, generating a stable elastic force. This elastic force continuously acts on the connecting ring and connecting plate, ensuring a tight fit between the top cover and the column, improving sealing stability in the non-working state and preventing debris from entering the equipment. In the working state, the top cover rises vertically, preventing dust or soil particles on its top from entering the riser or installation box and affecting the operation of components inside the installation box. The diameter of the top cover is the same as the outer diameter of the column, ensuring structural integrity and providing good shielding when retracted, enhancing the concealment and protection of the equipment.
[0008] Furthermore, the bottom surface of the top cover is provided with an outer ring, the outer diameter of which is the same as the outer diameter of the riser, and the top of the riser is provided with an inner ring, the outer diameter of which is the same as the inner diameter of the outer ring and the inner diameter of which is the same as the inner diameter of the riser, and the inner ring and the outer ring are inserted into each other.
[0009] By adopting the above technical solution, an outer ring and an inner ring are set. The outer ring on the bottom surface of the top cover is inserted and matched with the inner ring at the top of the riser, which further improves the sealing effect in the non-working state, effectively preventing rainwater, mud and other impurities from entering the riser and the interior of the mounting box, and protecting the components inside the mounting box.
[0010] Furthermore, a rubber gasket is provided on the bottom surface of the top cover inside the outer ring.
[0011] By adopting the above technical solution, the rubber gasket on the bottom surface of the top cover is located inside the outer ring. When the top cover is fitted with the riser, the inner ring presses the rubber gasket tightly, using its elastic deformation to fill the gap, further improving the sealing performance and preventing the infiltration of fine impurities or moisture.
[0012] Furthermore, the mounting box has vertically arranged slide rails on both sides of its inner wall, and the lifting plate is slidably connected to the two slide rails by two sliders on each side.
[0013] By adopting the above technical solution, slide rails and sliders are set to provide guidance for the lifting of the lifting plate, ensuring a smooth lifting process and improving the stability and reliability of the equipment operation.
[0014] Furthermore, the lifting assembly includes a threaded rod that is vertically rotatably mounted on the bottom surface of the mounting box, and a U-shaped plate is provided on the bottom surface of the lifting plate. The bottom of the U-shaped plate is helically connected to the threaded rod through a threaded hole.
[0015] By adopting the above technical solution, a threaded rod and a U-shaped plate are set up, and the threaded rod and the U-shaped plate are connected by a helical connection, which converts the rotational motion of the threaded rod into the linear lifting motion of the lifting plate, making it easier to control the lifting height of the lifting plate.
[0016] Furthermore, a worm gear is fixedly sleeved at the lower end of the threaded rod, and two fixing blocks are spaced apart on the bottom surface of the mounting box. A worm is horizontally rotatably arranged between the two fixing blocks. The worm cooperates with the worm gear. A fixing seat is provided on the bottom surface of the mounting box, and a drive motor is provided on the fixing seat. The output shaft of the drive motor is connected to the end of the worm.
[0017] By adopting the above technical solution, a fixed block and a worm gear are installed. The worm gear and worm wheel have a self-locking function, which prevents the lifting plate from descending on its own due to gravity or external forces when not in a driving state, ensuring the positional stability of the lifting plate in both working and non-working states. The drive motor provides stable power, which drives the worm wheel and threaded rod to rotate through the worm gear, thereby realizing the lifting control of the lifting plate.
[0018] Furthermore, the upper edge of the outer wall of the inner ring and the lower edge of the inner wall of the outer ring are chamfered.
[0019] Furthermore, the spray holder includes a vertical cylinder mounted on a lifting plate, a horizontal pipe connected to the outer wall of the vertical cylinder, the horizontal pipe being connected to an external water source, a cavity plate at the top of the vertical cylinder, the interior of the vertical cylinder being connected to the interior of the cavity plate, and a plurality of circumferentially spaced through holes being opened on the cavity plate, with spray heads installed in the through holes.
[0020] By adopting the above technical solution, external water enters the vertical cylinder through the horizontal pipe, then flows smoothly into the hollow plate at the top, and is finally sprayed out evenly by multiple spray heads arranged circumferentially.
[0021] In summary, this utility model has the following beneficial effects: This application includes an installation box, a riser, a lifting assembly, and a spray base. The lifting assembly drives the lifting plate to rise and fall, which in turn drives the spray base, column, and connecting plate to rise and fall synchronously, enabling the spray base to extend in the working state and retract in the non-working state, meeting the concealment requirements of pre-embedded equipment and reducing interference with the landscape. When the lifting plate lowers the lifting plate, spray base, column, and top cover until the top cover contacts the column, the distance between the connecting plate and connecting ring decreases as the lifting plate continues to descend. The spring is compressed and generates a stable elastic force, which continuously acts on the connecting ring and connecting plate, ensuring a tight fit between the top cover and the column, improving the sealing stability in the non-working state, and preventing debris from entering the equipment. In the working state, the top cover rises vertically, preventing dust or soil particles on its top from entering the riser or installation box, and thus not affecting the operation of the components inside the installation box. The diameter of the top cover is consistent with the outer diameter of the column, ensuring structural integrity and providing good shielding when retracted, enhancing the concealment and protection of the equipment.

[0029] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.
[0030] like Figure 1-6 As shown in the embodiment of this application, a pre-embedded garden maintenance spraying device is disclosed, including a mounting box 10, a riser 11, a lifting assembly 30, and a spray base 40. The riser 11 is connected to the top of the mounting box 10. A lifting plate 20 is vertically slidably arranged inside the mounting box 10. The lifting assembly 30 is arranged inside the mounting box 10 and is used to drive the lifting plate 20 to rise and fall. The spray base 40 is arranged on the lifting plate 20. A column 50 is vertically arranged on the top surface of the spray base 40. The column 50 is concentrically arranged with the riser 11. A connecting plate 51 is concentrically arranged at the upper end of the column 50. Several circumferentially spaced sliding holes are opened on the connecting plate 51. A sliding rod 52 is slidably arranged in the sliding holes. A connecting ring 53 is provided at the lower end of several sliding rods 52, and a circular top cover 54 is provided at the upper end. The connecting ring 53 and the top cover 54 are both concentrically arranged with the column 50. The diameter of the top cover 54 is the same as the outer diameter of the column 50. A spring 55 is sleeved on the rod 52 located between the connecting ring 53 and the connecting plate 51. The upper end of the spring 55 is connected to the bottom surface of the connecting plate 51, and the lower end is connected to the top surface of the connecting ring 53. The lifting assembly 30 drives the lifting plate 20 to rise and fall, which can drive the spray seat 40, the column 50, and the connecting plate 51 to rise and fall synchronously, realizing the extension of the spray seat 40 in the working state and the retraction in the non-working state, meeting the concealment requirements of the pre-embedded equipment and reducing interference with the garden landscape. When the lifting plate 20 drives the lifting plate 20, the spray seat 40, the column 50, and the top cover 54 to descend until the top cover 54 contacts the column 50, the lifting plate 20 continues to descend, the distance between the connecting plate 51 and the connecting ring 53 decreases, the spring 55 is compressed and generates a stable elastic force, which continuously acts on the connecting ring 53 and the connecting plate 51 to ensure that the top cover 54 and the column 50 fit tightly, improve the sealing stability in the non-working state, and prevent foreign objects from entering the equipment. In operation, the top cover 54 rises vertically, preventing dust or dirt particles from entering the riser 11 and mounting box 10, thus avoiding any impact on the operation of components within the mounting box 10. The diameter of the top cover 54 matches the outer diameter of the column 50, ensuring structural integrity while providing good concealment when retracted, enhancing the equipment's concealment and protection. The spring 55 and slide rod 52 are rust-proofed.
[0031] Specifically, an outer ring 56 is concentrically arranged on the bottom surface of the top cover 54, the outer diameter of which is the same as the outer diameter of the riser 11. An inner ring 12 is concentrically arranged on the top of the riser 11, the outer diameter of which is the same as the inner diameter of the outer ring 56, and the inner diameter of which is the same as the inner diameter of the riser 11. The inner ring 12 and the outer ring 56 are interlocked. The interlocking of the outer ring 56 on the bottom surface of the top cover 54 and the inner ring 12 on the top of the riser 11 further improves the sealing effect in the non-working state, effectively preventing rainwater, mud and other impurities from entering the riser 11 and the interior of the mounting box 10, protecting the components inside the mounting box 10. A rubber gasket 57 is provided on the bottom surface of the top cover 54 inside the outer ring 56. When the top cover 54 is engaged with the riser 11, the inner ring 12 presses the rubber gasket 57 tightly, using its elastic deformation to fill the gap, further improving the sealing performance and preventing the infiltration of fine impurities or moisture. The upper edge of the outer wall of the inner ring 12 and the lower edge of the inner wall of the outer ring 56 are chamfered. This chamfer serves as a guide when the two are inserted and mated, facilitating quick and accurate nesting and preventing structural jamming or damage caused by misalignment, thereby improving the sealing efficiency when not in operation.
[0032] To ensure smooth lifting and improve the stability and reliability of the equipment, slide rails 13 are vertically installed on the inner walls of opposite sides of the mounting box 10. The lifting plate 20 is slidably connected to the two slide rails 13 via two sliders 14 on each side. The lifting assembly 30 includes a threaded rod 31 vertically rotatably mounted on the bottom surface of the mounting box 10. A U-shaped plate 32 is mounted on the bottom surface of the lifting plate 20. The bottom of the U-shaped plate 32 is helically connected to the threaded rod 31 via a threaded hole. This helical connection converts the rotational motion of the threaded rod 31 into the linear lifting motion of the lifting plate 20, facilitating control of the lifting height. A worm gear 33 is fixedly fitted at the lower end of the threaded rod 31. Two fixed blocks 34 are spaced apart on the bottom surface of the mounting box 10. A worm gear 35 is horizontally rotatably mounted between the two fixed blocks 34. The worm gear 35 cooperates with the worm wheel 33; the rotation of the worm gear 35 drives the worm wheel 33 to rotate, thereby driving the threaded rod 31 to rotate. The worm gear 33 and worm 35 have a self-locking function, which prevents the lifting plate 20 from descending on its own due to gravity or external force when not in a driving state, ensuring the positional stability of the lifting plate 20 in both working and non-working states. A fixed base 36 is provided on the bottom surface of the mounting box 10, and a drive motor 37 is mounted on the fixed base 36. The drive motor 37 is an eccentric geared motor, and its output shaft is connected to the end of the worm 35. The drive motor 37 provides stable power, which drives the worm gear 33 and threaded rod 31 to rotate through the worm 35, thereby achieving the lifting control of the lifting plate 20.
[0033] In its specific configuration, the spray base 40 includes a vertical cylinder 41 mounted on the lifting plate 20. A horizontal pipe 42 is connected to the outer wall of the vertical cylinder 41, and the horizontal pipe 42 is connected to an external water source. A hollow plate 43 is mounted on the top of the vertical cylinder 41, and the diameter of the hollow plate 43 is smaller than the inner diameter of the vertical pipe 11. The interior of the vertical cylinder 41 is connected to the interior of the hollow plate 43. Several circumferentially spaced through holes are opened on the hollow plate 43, and spray heads 44 are installed in the through holes. The spray direction of the spray heads 44 is obliquely upward away from the hollow plate 43. The external water source enters the vertical cylinder 41 through the horizontal pipe 42, then flows smoothly into the top hollow plate 43, and is finally sprayed evenly by the multiple circumferentially spaced spray heads 44. The external water source can be a tap water pipe. A through hole is opened on the side wall of the mounting box 10 for the tap water pipe to pass through, and the through hole is sealed to the outer wall of the tap water pipe.
[0034] The operating principle of a pre-embedded garden maintenance spraying device in this embodiment is as follows: When not in operation, the lifting plate 20 is in a low position under the linkage of the drive motor 37, worm gear 35, worm wheel 33 and threaded rod 31. The top cover 54 is engaged with the inner ring 12 at the top of the riser 11 through the outer ring 56. The rubber gasket 57 is pressed to achieve a seal, and the spray seat 40 is retracted into the mounting box 10. When operation is required, the drive motor 37 starts and drives the worm gear 35 to rotate, which in turn causes the threaded rod 31 to rotate through the worm wheel 33, causing the U-shaped plate 32 and the lifting plate 20 to rise. This, in turn, causes the spray seat 40, the column 50 and the top cover 54 to rise synchronously. After the top cover 54 is separated from the riser 11, the external water source enters the vertical cylinder 41 through the horizontal pipe 42, then flows into the cavity plate 43 and is sprayed obliquely upward through multiple obliquely arranged spray heads 44. After the operation is completed, the drive motor 37 rotates in the reverse direction, causing the lifting plate 20 to descend. The top cover 54 re-engages with the riser 11, restoring the sealing state and completing the entire operation process.
[0035] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
