Description

Technical Field

[0001] The invention relates to the technical field of spraying, and in particular to a tree trunk insect repellent spraying device and a spraying method. Background Art

[0002] In cities, with the gradual development of the economy and improvement of urbanization, urban residents have higher and higher requirements for the ecological environment of their living areas. Coupled with the development of greening technology, the demand for vegetation diversity and various greening needs, more and more different types of trees are being introduced into urban greening projects.

[0003] In the prior art, a Chinese patent with publication number "CN217411155U" discloses a tree trunk spraying device for garden maintenance, in which a first U-shaped frame and a second U-shaped frame are moved to both sides of a tree trunk to be sprayed by a movable base, and then both ends of the second U-shaped frame are inserted into the first U-shaped frame, so that the tree trunk is surrounded by the first U-shaped frame and the second U-shaped frame. When a paint pump is turned on, the paint in the paint box can be sprayed through a paint pipe and a paint spray port to the outer surface of the tree trunk to achieve spraying. At the same time, an electric push rod can drive the first U-shaped frame and the second U-shaped frame to rise and fall, so that paint can be sprayed on different heights of the outer surface of the tree trunk without manual spraying, thereby reducing the use of manpower and improving spraying efficiency, thereby solving the problem that the existing manual whitewashing requires a lot of time and manpower and has low overall efficiency.

[0004] In order to avoid being damaged by insects, the existing tree trunks need to be whitewashed on the surface. Since the effect of manual whitewashing is low, a spraying device is usually used for spraying. As in the scheme described above, two U-shaped frames are manually merged by personnel, and the paint spraying port on the U-shaped frame is used to achieve the whitewashing effect. However, during spraying, due to the fixed position of the paint spraying port, some positions of the tree trunk cannot be effectively sprayed, resulting in poor spraying effect. In addition, the two U-shaped frames need to be manually pushed, and the positions of the two U-shaped frames need to be manually adjusted. This not only takes time to align, but also wastes manpower.

5. A tree trunk insect repellent spraying device according to claim 4, characterized in that: The adjustment assembly comprises an adjustment slot (33) arranged on the driving gear (24), an adjustment block (34) being slidably connected inside the adjustment slot (33), a limit rod (35) being fixedly mounted on the adjustment block (34), a rotating rod (36) being rotatably connected to the limit rod (35), an extension slot (37) being provided on the rotating rod (36), an extension plate (38) being slidably connected inside the extension slot (37), one end of the extension plate (38) being fixedly connected to the driving rod (26), a plurality of threaded holes (39) being provided on the extension plate (38) and the extension slot (37), and an adjustment bolt (40) being threadedly connected inside the threaded hole (39).

6. A tree trunk insect repellent spraying device according to claim 5, characterized in that: A collecting pipe (41) is fixedly mounted on the lower end surface of the mounting block (1); a liquid inlet pipe (42) is fixedly connected to the collecting pipe (41); a connecting pipe (43) is fixedly connected to the side end surface of the collecting pipe (41); an end of the connecting pipe (43) away from the collecting pipe (41) is fixedly connected to a telescopic hose (44); an end of the telescopic hose (44) away from the collecting pipe (41) is fixedly connected to a connecting pipe (45); and an end of the connecting pipe (45) away from the telescopic hose (44) is fixedly connected to the discharge pipe (4).

7. A method for spraying an insect repellent on a tree trunk, based on a tree trunk insect repellent spraying device as described in claim 6, characterized in that: The following steps are involved: S1. When in use, the first electric push rod (6) is used to drive the double-sided toothed plate (8) to move outward, and the double-sided toothed plate (8) is meshed with the driven gear (10) to merge the opened arc-shaped plates (3), so that the two arc-shaped plates (3) surround the outside of the tree trunk; S2, then pull the mounting block (1) to make the upper limit wheel (16) of the second L-shaped block (14) fit the tree trunk, and at the same time drive the first L-shaped block (13) to move toward the tree trunk through the second electric push rod (12), so that the upper limit wheel (16) on the first L-shaped block (13) fits the tree trunk, and the arc plate (3) is limited by the two upper limit wheels (16), and then the driving gear (24) is driven to rotate by the motor (23), and the driving gear (24) cooperates with the first tooth block (20) on the arc plate (3) to spray the tree trunk with the nozzle (5) on the discharge pipe (4); S3. When the driving gear (24) rotates, the driving gear (24) drives the U-shaped frame plate (29) to move back and forth horizontally through the adjustment component, and the second gear block (31) on the U-shaped frame plate (29) cooperates with the auxiliary gear (32) on the connecting shaft (25), so that the nozzle (5) on the discharge pipe (4) is in a swinging state, ensuring that the spraying effect of the nozzle (5) is better; S4. When it is necessary to adjust the swing angle of the nozzle (5), the adjusting bolt (40) is removed and the position of the adjusting block (34) is adjusted. After the position of the adjusting block (34) is adjusted, the extension plate (38) in the extension groove (37) is adjusted synchronously. Finally, the extension plate (38) is re-fixed by the adjusting bolt (40).
