[0008] The lifting assembly includes a slide plate movably connected to the output end of a spring telescopic rod, a triangular plate is fixed on the side of the slide plate, the output end of the spring telescopic rod is fixed on the triangular plate, spring telescopic rods are fixed at corresponding positions on the upper and lower parts of the connecting plate, and the output ends of the two spring telescopic rods are fixed to corresponding positions at both ends of the rear side of the slide plate. When any end of the slide plate is subjected to force, the output end of the spring telescopic rod at the force-bearing end is retracted inward, and the output end of the spring telescopic rod at the other end is extended outward, so that the slide plate is inclined, which can meet the needs of spraying tree trunks with different inclinations.

[0009] The regulating component includes a mover slidably connected to the slide rail plate, and a track plate is fixed on the mover. When the spraying component sprays the tree trunk, the mover slides up and down on the side of the slide rail plate to achieve the effect of uniform spraying on the required spraying parts of the tree trunk.

[0010] The spraying assembly includes a moving block slidably connected to the track plate, an arc tube is fixed on the side of the moving block, a spray hole is opened on the side of the arc tube, both ends of the track plate are slidably connected to the moving blocks, and the two moving blocks are fixed with arc tubes. When the moving block approaches the middle, the two arc tubes are closed to form a circular ring, which has the effect of being sleeved on the side of the trunk, and the moving block moves in the opposite direction to separate the two arc tubes so that they can be detached from the trunk.

[0011] As a further improvement of the above scheme, a connecting tube is fixed on the slide rail plate, an extension rod is movably sleeved in the connecting tube, and a regulating ring is movably hinged at one end of the connecting tube, and the extension rod is threadedly connected in the regulating ring.

[0012] Through the above technical solution, when the regulating ring is rotated clockwise or counterclockwise, the extension rod is telescopically moved under the force of the threaded connection between the inner side of the regulating ring and the side of the extension rod, and the overall length of the extension rod and the connecting tube is adjusted, so that when the arc tube is sleeved on the side of the trunk, the extension rod can be tightly attached to the side of the trunk, and the slide plate is tilted according to the inclination of the trunk to ensure that the slide plate and the trunk are in a parallel state.

[0014] Through the above technical solution, the output end of the micro motor has the function of bidirectional rotation. When rotating clockwise, the mover moves downward, and when rotating counterclockwise, the mover moves upward. When the arc tube is spraying, with the cooperation of the mover, the effect of uniform spraying of the trunk part can be achieved.

[0015] As a further improvement of the above solution, a drive box is fixed in the track plate, and a spiral rod and an auxiliary rod are movably hinged on the side of the drive box.

[0016] Through the above technical solution, spiral rods are movably hinged at corresponding positions on the top of both sides of the drive box, and auxiliary rods are movably hinged at corresponding positions on the bottom of both sides. The threads of the two spiral rods are opposite.

[0017] As a further improvement of the above scheme, a driving motor is fixed in the driving box, a driving gear is fixed to the output end of the driving motor, and a transmission gear is fixed to the side of the spiral rod. The driving gear and the side of the transmission gear are movably connected with a transmission track, and the transmission gear is fixed to one end of the spiral rod.

[0018] Through the above technical solution, the output end of the driving motor has the function of bidirectional rotation. When the output end rotates, the driving gear rotates, and the transmission gear is driven to rotate at the same time through the transmission track, so that the spiral rod rotates.

[0019] As a further improvement of the above solution, the moving block is threadedly connected to the side of the spiral rod and movably sleeved on the auxiliary rod, and the spiral rod and the auxiliary rod are fixed with limit buttons, which fit the side of the moving block.

[0020] Through the above technical solution, when the spiral rod rotates clockwise, the moving block moves outward, and when the spiral rod rotates counterclockwise, the moving block moves toward the middle, thereby realizing the operation effect of expanding and closing the arc tube. When the moving block moves, it slides on the side of the auxiliary rod at the same time, thereby increasing the stability of the movement of the moving block. When the moving block moves to the front end of the spiral rod, it is limited by the limit button to prevent the moving block from detaching from the spiral rod and the auxiliary rod.

[0021] As a further improvement of the above solution, a water delivery interface is provided on the side of the arc-shaped tube, and a water delivery pipe is threadedly connected to the water delivery interface.

[0022] Through the above technical solution, one end of the water pipe is installed on the water pipe, and the other end is installed on the supply box.

[0025] 2. The maintainable municipal greening spraying device can meet the distance of the spraying tube sleeved on the side of the tree trunk for spraying by adjusting the extended length of the extension rods at both ends of the slide rail plate clockwise and counterclockwise. In addition, the extended lengths of the two extension rods can be adjusted to different degrees to achieve a uniform spraying effect for some tree trunks that are thick at the bottom and thin at the top, thereby further improving its practicality.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0038] Embodiment 1

[0039] See also Figure 1-6 As shown, the maintainable municipal greening spraying device proposed in this embodiment includes a supporting component 1, a lifting component 2, an adjusting component 3 and a spraying component 4, the supporting component 1 includes a fixed bracket 101 installed on a mobile vehicle, a supporting rod 102 is fixed on the fixed bracket 101, a connecting plate 103 is fixed on the front end of the supporting rod 102, a spring telescopic rod 104 is fixed on the connecting plate 103, the fixed bracket 101 is L-shaped, and the bottom is fixed on the mobile vehicle to fix the spraying device, and when the mobile vehicle moves, the spraying device is driven to move at the same time, and a storage box for feeding the spraying component 4 can be installed on the mobile vehicle, and the spraying component 4 can be fed with materials in real time.

[0040] The lifting component 2 includes a slide plate 201 movably connected to the output end of the spring telescopic rod 104, a triangular plate 202 is fixed to the side of the slide plate 201, the output end of the spring telescopic rod 104 is fixed on the triangular plate 202, and the spring telescopic rods 104 are fixed to the corresponding positions on the upper and lower parts of the connecting plate 103, and the output ends of the two spring telescopic rods 104 are fixed to the corresponding positions at both ends of the rear side of the slide plate 201. When any end of the slide plate 201 is subjected to force, the output end of the spring telescopic rod 104 at the force-bearing end is retracted inward, and the output end of the spring telescopic rod 104 at the other end is extended outward, so that the slide plate 201 is inclined, which can meet the needs of spraying tree trunks with different inclinations.

[0041] The regulating component 3 includes a mover 301 slidably connected to the slide plate 201, and a track plate 302 is fixed on the mover 301. When the spraying component 4 sprays the tree trunk, the mover 301 slides up and down on the side of the slide plate 201 to achieve the effect of uniform spraying on the required spraying parts of the tree trunk.

[0042] The spraying assembly 4 includes a moving block 401 slidably connected in the track plate 302, an arc tube 402 is fixed to the side of the moving block 401, a spray hole 403 is opened on the side of the arc tube 402, and moving blocks 401 are slidably connected to both ends of the track plate 302, and arc tubes 402 are fixed on the two moving blocks 401. When the moving block 401 approaches the middle, the two arc tubes 402 are closed to form a circular ring, which has the effect of being sleeved on the side of the trunk, and the moving block 401 moves in the opposite direction, so that the two arc tubes 402 are separated, so that they can be detached from the trunk.

[0043] The working principle of the maintainable municipal greening spraying device proposed in this embodiment is as follows: when in use, the extension rod 205 is moved outward by rotating the regulating ring 204 to adjust the distance between the extension rod 205 and the side of the support rod. After the adjustment is completed, the mobile vehicle is pushed close to the side of the tree trunk to be sprayed, and the front end of the extension rod 205 is closely attached to the side of the tree trunk. According to the inclination angle of the tree trunk, the spring telescopic rods 104 at both ends of the connecting plate 103 are telescopically moved, so that the slide plate 201 is parallel to the tree trunk, and at the same time, the two arc tubes 402 are located on both sides of the tree trunk in the open state. At this time, the driving motor 304 is controlled to operate, so that the output end drives the driving gear 305 to rotate, and drives the transmission gear 307 to rotate through the transmission crawler 306, so that the spiral rod 308 rotates, and under the force of the internal thread connection with the moving block 401, the moving block 401 is moved closer to the middle. At this time, the two arc tubes 402 are closed toward the middle and completely sleeved on the side of the trunk. At this time, the feed box on the motor vehicle is controlled to transport lime liquid into the arc tube 402 through the water pipe 405. After the lime liquid forms pressure in the arc tube 402, it is sprayed onto the trunk from the spray hole 403, and the micro motor 208 is controlled to operate so that the threaded rod 209 rotates. Under the force of the threaded connection between the threaded rod 209 and the inner thread of the mover 301, the mover 301 moves up and down to evenly spray the trunk part. After the spraying is completed, the output end of the drive motor 304 is controlled to operate in the reverse direction so that the screw rod 308 rotates in the reverse direction. At this time, the moving block 401 moves in the reverse direction to separate the two arc tubes 402. Then, the moving vehicle is pulled to separate the arc tube 402 from the sprayed trunk and then move it to the side of the trunk to be sprayed. The above steps are repeated to achieve the effect of spraying different trunks.

[0044] Furthermore, a connecting tube 203 is fixed on the slide rail plate 201 , and an extension rod 205 is movably sleeved in the connecting tube 203 . At the same time, a regulating ring 204 is movably hinged at one end of the connecting tube 203 , and the extension rod 205 is threadedly connected in the regulating ring 204 .

[0045] More specifically, by rotating the regulating ring 204 clockwise or counterclockwise, the extension rod 205 is telescopically moved under the force of the threaded connection between the inner side of the regulating ring 204 and the side of the extension rod 205, and the overall length of the extension rod 205 and the connecting tube 203 is adjusted, so that when the arc tube 402 is sleeved on the side of the trunk, the extension rod 205 can be tightly attached to the side of the trunk, and according to the inclination of the trunk, the slide plate 201 is tilted to ensure that the slide plate 201 and the trunk are in a parallel state.

[0046] Furthermore, a limiting groove 206 is opened in the slide rail plate 201, and connecting plates 207 are vertically fixed at both ends of the limiting groove 206. A micro motor 208 is fixed on the connecting plate 207. The output end of the micro motor 208 passes through the connecting plate 207 and is fixed with a threaded rod 209. The mover 301 is threadedly connected to the threaded rod 209.

[0047] More specifically, the output end of the micro motor 208 has the function of bidirectional rotation. When rotating clockwise, the mover 301 moves downward, and when rotating counterclockwise, the mover 301 moves upward. When the arc tube 402 is spraying, with the cooperation of the mover 301, the effect of uniformly spraying the trunk part up and down is achieved.

[0048] Furthermore, a driving box 303 is fixed inside the track plate 302 , and a spiral rod 308 and an auxiliary rod 309 are movably hinged on the side of the driving box 303 .

[0049] More specifically, spiral rods 308 are movably hinged at corresponding positions on the top of both sides of the drive box 303, and auxiliary rods 309 are movably hinged at corresponding positions on the bottom of both sides. The threads of the two spiral rods 308 are opposite. When the spiral rods 308 rotate, the moving block 401 moves on the auxiliary rods 309 at the same time, thereby improving the stability of the movement of the moving block 401.

[0050] Furthermore, a driving motor 304 is fixed in the driving box 303, a driving gear 305 is fixed to the output end of the driving motor 304, and a transmission gear 307 is fixed to the side of the spiral rod 308. The sides of the driving gear 305 and the transmission gear 307 are movably connected with a transmission track 306, and the transmission gear 307 is fixed to one end of the spiral rod 308.

[0051] More specifically, the output end of the driving motor 304 has the function of bidirectional rotation. When the output end rotates, the driving gear 305 rotates, and the transmission gear 307 is driven to rotate at the same time through the transmission track 306, so that the spiral rod 308 rotates.

[0052] In addition, it should be further explained that screw rods 308 are fixed at both ends of the transmission gear 307, and the threads on the sides of the screw rods 308 at both ends are opposite, so that when the transmission gear 307 rotates clockwise or counterclockwise, the moving blocks 401 at both ends move synchronously toward the middle or both ends.

[0053] Furthermore, the moving block 401 is threadedly connected to the side of the spiral rod 308 and movably sleeved on the auxiliary rod 309 , and a limit button 310 is fixed on the spiral rod 308 and the auxiliary rod 309 , and the limit button 310 is attached to the side of the moving block 401 .

[0054] More specifically, when the spiral rod 308 rotates clockwise, the moving block 401 moves outward, and when the spiral rod 308 rotates counterclockwise, the moving block 401 moves toward the middle, thereby realizing the operation effect of expanding and closing the arc tube 402. When the moving block 401 moves, it also slides on the side of the auxiliary rod 309 to increase the stability of the movement of the moving block 401. When the moving block 401 moves to the front end of the spiral rod 308, it is limited by the limit button 310 to prevent the moving block 401 from detaching from the spiral rod 308 and the auxiliary rod 309.

[0055] Furthermore, a water delivery interface 404 is provided on the side of the arc-shaped tube 402 , and a water delivery pipe 405 is threadedly connected to the water delivery interface 404 .

[0056] More specifically, one end of the water pipe 405 is installed on the water pipe 405, and the other end is installed on the supply box. The tree trunk whitening agent stored in the supply box is input into the arc tube 402 through the water pipe 405. After the whitening agent forms pressure in the arc tube 402, it is sprayed on the tree trunk from the spray hole 403.

[0057] 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.
