Description

Technical Field

[0001] The invention relates to the technical field of spraying systems, and in particular to a high-efficiency and environmentally friendly spraying system for garden trees. Background Art

[0002] As we all know, the high-efficiency and environmentally friendly spraying system for garden trees is a high-efficiency spraying operation system that combines the concept of environmental protection, aiming to provide scientific, efficient and environmentally friendly spraying maintenance solutions for garden trees.

[0003] After searching, the Chinese patent publication number CN221890189U and the Chinese patent publication number CN116637746A respectively disclose a tree antifreeze spraying device and an automatic tree painting device. The former is roughly described as including a base for support and a spraying assembly installed on the base. There are at least two bases, and the two bases form an enclosed area. The base includes a base body, and a gear ring is provided on the top of the base body. The gear ring is adapted to the spraying assembly. When in use, it can rotate along the set gear ring through the combination of the set arc plate and the set spray strip under the action of the driving motor and the gear, so as to rotate the area of ​​the tree that needs to be sprayed. The latter is roughly described as including a liquid storage barrel, a support ring, a spray head, a telescopic frame and a counterweight barrel. The liquid storage barrel is used to contain the spraying liquid. The liquid storage barrel is provided with a first water pump and a lead-out pipe. The support ring includes two detachably connected semicircular rings, and the spray head is fixed on the support ring. The telescopic frame includes a support platform that can be lifted vertically, the support ring is installed on the support platform, and a first driving source is arranged on the telescopic frame, and a second driving source for driving the support platform to be lifted and lowered is arranged on the telescopic frame, one end of the lead-out pipe is connected to the counterweight barrel, and the nozzle is connected to a spraying pipe connected to the counterweight barrel, and a second water pump is arranged in the counterweight barrel, and a water outlet end of the second water pump is connected to a reflux pipe that leads the spraying liquid back to the liquid storage barrel. When in use, after one semicircular ring is removed, the telescopic frame is placed on one side of the tree trunk, and two semicircular rings are fixed so that the support ring surrounds the circumference of the tree trunk, the counterweight barrel is removed from the first fixed platform on the liquid storage barrel and then installed on the second fixed platform, by starting the first water pump, the spraying liquid enters the counterweight barrel and continues to be sprayed out at the nozzle when moving through the spraying pipe, the first driving source is started to drive the support ring to rotate, and the second driving source is driven to make the driving ring and the support platform slowly descend, so that the nozzle can rotate around the tree trunk and slowly descend, thereby spraying the tree trunk.

[0004] Although the above two existing technical solutions can carry out spraying operations in the areas where trees need to be sprayed, both of them can only realize spraying operations in the inner area of ​​the ring, that is, they are more suitable for spraying operations relative to the trunks of trees. The operation area is relatively limited, and the functionality needs to be further strengthened.

In the present invention, we only use them and have not improved their structure and function. For those skilled in the art, their setting method, installation method and electrical connection method only need to be debugged and operated according to the requirements of their instruction manual, and will not be described in detail here.

[0040] In summary, the working principle of the high-efficiency and environmentally friendly spraying system for garden trees is as follows: when in use, firstly, the battery in the high-efficiency and environmentally friendly spraying system for garden trees is checked for power to ensure the battery power, and the material to be sprayed is loaded into the material box 2, and a feeding port is provided on the material box 2, and the loading of the material is realized through the feeding port, and then the command signal is transmitted to the central controller through the external handheld control terminal, and the central controller converts the signal after receiving the command signal, and transmits the converted signal to the crawler body 1, the first servo motor 15, the second servo motor 27, the pump group 3 and the hydraulic group to realize the operation of the high-efficiency and environmentally friendly spraying system for garden trees. When the crawler body 1 is in the moving state, the overall state of the high-efficiency and environmentally friendly spraying system for garden trees is as shown in the attached figure. Figure 1As shown, in this state, the air cylinder 4 and the mounting cylinder 5 are both arranged vertically. Keeping this state, the control pump group 3 can work to extract the material in the material box 2 and pump it into the two liquid inlet pipes 11. Since the material entering the two liquid inlet pipes 11 has a certain hydraulic pressure, the material in the liquid inlet pipes 11 will be sprayed out at high speed through multiple nozzles 14, and will be dispersed and atomized by the shielding operation of the door-type atomizing plate 42. Since the door-type atomizing plate 42 is perpendicular to the direction of the liquid inlet pipe 11 on which it is installed, the door-type atomizing plate 42 will form a shield in the direction of the inner front wall and the inner rear wall of the semi-annular sleeve 10, reducing the sprayed material. Regarding the adhesion of the semi-annular sleeve 10, the fan is controlled to run while the material is sprayed out from the nozzle 14. The fan runs to send air into the two induced draft ducts 7, and the air entering the induced draft ducts 7 is finally discharged from the diffuser 8. Due to the corresponding nested positions of the diffuser 8 and the nozzle 14, the air blown out from the diffuser 8 will form a secondary acceleration for the material sprayed from the nozzle 14, so as to increase the initial velocity of the atomized material. Taking into account that many garden trees are planted in multiple rows under actual circumstances, when the crawler body 1 moves between two adjacent rows of garden trees, the synchronous spraying operation of the two adjacent rows of trees can be achieved, and the operation efficiency is higher.

[0041] Furthermore, when it is necessary to spray the trunks of garden trees, firstly, the hydraulic cylinder 24 is turned over to work, so that the two rotating links 25 are rotated and raised, that is, the attached Figure 1 The status shown enters the attached Figure 5 In the state shown in the figure, during this process, the wind tube 4 and the installation tube 5 will form a synchronous rotation and rise along with the rotation and rise of the two rotating connecting frames 25, and then the multi-stage hydraulic cylinder 16 works to realize the synchronous push-out of the two half-rings 10 relative to the installation tube 5, that is, the attached Figure 5 The status shown enters the attached Figure 7 , Attachment Fig. 9 and attached Fig.11 In the state shown, during the process, the multi-stage hydraulic cylinder 16 will cause the two semi-ring sleeves 10 to slide synchronously relative to the mounting tube 5 at the initial stage of operation, that is, the inner connecting shaft 17 slides in the inner connecting groove 19, and the outer connecting shaft 18 slides in the outer connecting groove 20. With the further movement of the multi-stage hydraulic cylinder 16, when the inner connecting shaft 17 slides to the limit position relative to the inner connecting groove 19, and the outer connecting shaft 18 slides to the limit position relative to the outer connecting groove 20, the multi-stage hydraulic cylinder 16 continues to drive the synchronous plate 22 to move. The moving synchronous plate 22 will further drive the two semi-ring sleeves 10 under the transmission action of the two driving springs 21. The drive will realize the rotation of the semi-ring sleeves 10 relative to the mounting tube 5, that is, the mounting ends of the first servo motors 15 on the two semi-ring sleeves 10 rotate away from each other, so as to facilitate the trunk of the tree to enter the area enclosed by the two semi-ring sleeves 10, so as to attach Fig. 9For initial reference, the relative position of the tree trunk and the two semi-rings 10 is controlled by the movement of the crawler body 1, so that the tree trunk enters the two semi-rings 10, and then the multi-stage hydraulic cylinder 16 is used to control the rotation and opening amplitude of the two semi-rings 10, so that the two semi-rings 10 enter a closed posture relative to the tree trunk, and then the two first servo motors 15 work to realize the rotation drive of the two air ducts 7 respectively. The rotation of the two air ducts 7 will respectively drive the liquid guide pipes 11 therein to rotate synchronously, forming a change in the direction of the nozzle 14, and after the nozzle 14 is controlled to enter the corresponding position of the inner arc-shaped strip mouth 40, the pump group 3 is started to make the nozzle 14 spray out the material, and the two second servo motors 27 are started at the same time. The two second servo motors 27 work to control the two sliding frames 26 to form a synchronous movement and rise, thereby realizing the synchronous rise of the wind tube 4 and the mounting tube 5. With the rise of the mounting tube 5, the nozzle 14 and the brush strip 12 are synchronously risen to achieve the spraying operation of the tree trunk at different heights.

[0042] Furthermore, if the spray material of the tree trunk needs to be thicker and needs to be achieved through repeated spraying, when the semi-annular sleeve 10 forms a relative drop spraying relative to the tree trunk, the first servo motor 15 controls the nozzle 14 to enter the corresponding position of the outer arc strip opening 41, so that the brush strip 12 can closely follow the area where the nozzle 14 passes, and the material sprayed from the nozzle 14 but not in relative contact with the tree trunk is captured, thereby reducing the external diffusion of the material and ensuring a better environmental protection effect. In addition, the material captured by the brush strip 12 can also be relatively A secondary coating is formed on the tree trunk to further ensure the spraying effect of the tree trunk, and in this state, the operating power of the fan in the wind tube 4 is controlled to control the appropriate wind speed in the air outlet 8 to ensure the acceleration of the material sprayed from the nozzle 14 while increasing the air flow around the tree trunk, thereby improving the curing or drying efficiency of the material sprayed on the tree trunk, and when working in a cold environment, a resistance wire can be installed in the wind tube 4 to make the air sent out from the air outlet 8 have a certain temperature to further improve the curing or drying efficiency of the material sprayed on the tree trunk.

[0043] 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.
