Technical Field

[0001] This utility model belongs to the field of garden tool technology, specifically relating to a tree trunk protectant spraying device. Background Technology

[0002] In the process of greening, white protective paint is often applied to the bottom of the tree trunk to protect the trees. Currently, the following two methods are commonly used to apply protective paint to the tree trunk: (1) manual painting, where the protective paint is brushed onto the tree trunk surface by hand. This method is labor-intensive and inefficient, which greatly increases the cost of landscaping construction; (2) manual spraying, where the protective paint is sprayed onto the tree trunk using a spraying device. However, most of the spraying devices on the market are handheld, and the spraying area of ​​the spraying device cannot be adjusted, making it unsuitable for spraying tree trunks of different diameters, which affects work efficiency.

Detailed Implementation

[0020] The present invention will now be further described with reference to the accompanying drawings.

[0021] A trunk protectant spraying device includes a frame 1, a paint delivery assembly 2, a spray pipe 3, and an adjustment mechanism 4. The paint delivery assembly 2 and the adjustment mechanism 4 are fixed on the frame 1. The spray pipe 3 is connected to the paint delivery assembly 2 and installed on the adjustment mechanism 4. The height of the spray pipe 3 is adjusted by the adjustment mechanism 4, so that the spray pipe 3 can move up and down, which facilitates spraying at a certain height on the trunk.

[0022] The frame 1 includes a base plate 1-1 and casters 1-2 fixed on the base plate 1-1. The frame 1 can be moved as needed, improving the ease of use of the device. The material conveying assembly 2 and the adjusting mechanism 4 are respectively installed on the base plate 1-1. As a preferred embodiment, to prevent the base plate 1-1 from interfering with the tree trunk when using the device, the spray pipe 3 is arranged on the outer edge of the base plate 1-1.

[0023] The paint delivery assembly 2 includes a storage cylinder 2-1, a delivery pump 2-2, and a flexible pipe 2-3. The storage cylinder 2-1 stores the protective paint. The delivery pump 2-2 is connected to the storage cylinder 2-1 and to the spray pipe 3 via the flexible pipe 2-3. The delivery pump 2-2 delivers the protective paint to the spray pipe 3, and then the protective paint is sprayed onto the tree trunk through the spray pipe 3. An end cap 2-4 is provided at the top of the storage cylinder 2-1 to facilitate the filling of the storage cylinder 2-1 with protective paint by the construction personnel. Preferably, this device is equipped with a storage battery to power the delivery pump 2-2, ensuring its operation.

[0024] The spray pipe 3 includes a U-shaped pipe 3-3 and a connecting pipe 3-4 vertically connected to the middle of the U-shaped pipe 3-3. Multiple spray nozzles 3-1 are evenly distributed on the side wall of the U-shaped pipe 3-3. Preferably, the spray nozzles 3-1 are arranged facing the inside of the U-shaped pipe 3-3. During the spraying process, the tree trunk is inserted into the U-shaped pipe 3-3, so that the multiple spray nozzles 3-1 can spray the tree trunk.

[0025] A sleeve 5 is slidably installed on the outside of the U-shaped fitting 3-3. The sleeve 5 is adapted to the spray nozzle 3-1. That is, by adjusting the positional relationship between the sleeve 5 and the U-shaped fitting 3-3, the number of spray nozzles 3-1 on the spray pipe 3 blocked by the sleeve 5 is changed, thereby adjusting the number of spray nozzles 3-1 used for spraying. This achieves adjustment of the spraying area of ​​the U-shaped fitting 3-3, ensuring that the spraying area of ​​the U-shaped fitting 3-3 matches the diameter of the tree trunk, improving spraying efficiency, and reducing the waste of protective paint. In some preferred embodiments, a nozzle 3-2 is provided on the spray nozzle 3-1. The tree trunk is sprayed through the nozzle 3-2, improving the uniformity of the protective paint spraying.

[0026] The adjustment mechanism 4 includes an adjustment frame 4-3, a movable frame 4-4, and an adjustment component. The adjustment frame 4-3 is fixed to the frame 1, and the movable frame 4-4 is slidably mounted on the adjustment frame 4-3. The spray pipe 3 is connected to the movable frame 4-4, and the adjustment component is connected to the movable frame 4-4 to drive the movable frame 4-4 to rise and fall. The adjustment frame 4-3 provides guidance for the rising and falling of the movable frame 4-4, ensuring that the movable frame 4-4 remains parallel to the frame 1 during the rising and falling process, and preventing the swaying of the movable frame 4-4 during the rising and falling process from affecting the uniformity of the protective paint spraying.

[0027] The adjusting components include an adjusting rod 4-5 and a support frame 4-6. The support frame 4-6 is fixed on the machine frame 1. The middle part of the adjusting rod 4-5 is rotatably mounted on the support frame 4-6. A connecting groove 4-7 is provided on the adjusting rod 4-5. The movable frame 4-4 is connected to the connecting groove 4-7 through a connecting shaft. The movable frame 4-4 is raised and lowered by swinging the adjusting rod 4-5. During the raising and lowering of the movable frame 4-4, the connecting shaft and the connecting groove 4-7 slide relative to each other to prevent the swinging rod 4-5 from interfering.

[0028] An installation slot 4-1 is provided on the movable frame 4-4. An installation block 6 is connected to the spray pipe 3. The installation block 6 is slidably installed in the installation slot 4-1. A locking screw 4-2 is provided in the installation slot 4-1 to lock the installation block 6. In order to ensure that the spray pipe 3 is closer to the bottom of the tree trunk, the height of the spray pipe 3 is first adjusted so that the spray pipe 3 is close to the bottom of the tree trunk, and then the installation block 6 is locked by the locking screw 4-2.

[0029] The operating method of this spraying device is as follows:

[0030] (1) Adjust the height of the spray pipe 3 by installing block 6 to ensure that the spray pipe 3 is close to the bottom of the tree trunk, and manually push the frame 1 so that the spray pipe 3 is inserted into the outside of the vertical pole.

[0031] (2) The delivery pump 2-2 works to deliver the protective paint in the storage cylinder 2-1 to the spray pipe 3, and the spray pipe 3 sprays the tree trunk;

[0032] (3) Manually drive the adjusting rod 4-5 to swing, so that the movable frame 4-4 rises and falls, driving the spray pipe 3 to rise and fall, so as to spray the tree trunk once. In order to ensure the uniformity of the protective paint spraying, after the first spraying, drive the frame 1 to move a certain distance around the tree trunk as the center and then carry out a second spraying to ensure that the outer wall of the tree trunk is completely covered by the protective paint.
