[0019] Please refer to Figure 1-Figure 3 As shown, the utility model provides a tree trunk painting device for greening engineering, the upper end of the base 1 is fixedly connected with a bracket 13, the upper end of the bracket 13 is provided with a motor 14, the output end of the motor 14 passes through the bracket 13 and is fixedly connected to the threaded rod 15, one end of the threaded rod 15 is rotatably connected to the base 1, and a connecting block 17 is threadedly connected to the threaded rod 15, one end of the connecting block 17 is fixedly connected to the connecting plate 2, and a limiting column 16 is fixedly connected between the bracket 13 and the base 1, the limiting column 16 passes through the connecting block 17, and the limiting column 16 can limit the connecting block 17, a paint box 18 is provided on the upper end of the base 1, a material delivery pipe 19 is provided on one side of the paint box 18, one end of the material delivery pipe 19 is connected with a telescopic hose 20, one end of the telescopic hose 20 is connected with the arc tube 11, a pressure pump 21 is provided on the material delivery pipe 19, a pair of push rods 22 are fixedly connected to the upper end of the base 1, and pulleys 23 are fixedly connected at the top corners of the lower end of the base 1.

[0020] When in use, by starting the motor 14, the motor 14 can drive the threaded rod 15 to rotate, and the rotation of the threaded rod 15 can drive the connecting block 17 to move. Under the limiting action of the limiting column 16, the connecting block 17 can move more stably. The movement of the connecting block 17 can indirectly drive the arc tube 11 to move, and then the tree trunk can be well painted.

[0021] As a further implementation of this embodiment, Figure 1-Figure 4 As shown, a pair of slide grooves 3 are opened in the connecting plate 2, and a slide plate 4 is slidably arranged in the slide groove 3. A plurality of limiting holes 5 are opened at the upper end of the slide plate 4, and the limiting holes 5 are arranged at equal intervals. A pair of springs 7 are fixedly connected between the connecting plate 2 and the cross plate 6, and a pair of limiting rods 8 are fixedly connected to the lower end of the cross plate 6. One end of the limiting rod 8 passes through the connecting plate 2 and is inserted into the limiting hole 5. A handle 9 is arranged at the upper end of the connecting plate 2, and the handle 9 is located at the center position of the upper end of the connecting plate 2. A fixed plate 10 is fixedly connected to one side of the slide plate 4, and an arc tube 11 is fixedly connected to the fixed plate 10. A plurality of nozzles 12 are arranged on the arc tube 11, and the nozzles 12 are arranged at equal intervals.

[0022] When in use, by holding the handle 9 and pulling the cross plate 6 upwards, the spring 7 is stretched and the limiting rod 8 is driven to leave the limiting hole 5, and then the slide plate 4 in the slide groove 3 is pulled to make the slide plate 4 slide in the slide groove 3. The movement of the slide plate 4 can drive the fixed plate 10 and the arc tube 11 to move, thereby changing the distance between the two arc tubes 11. When the slide plate 4 moves to a suitable distance, stop pulling the handle 9, so that the cross plate 6 moves downward under the elastic force of the spring 7 until the limiting rod 8 is inserted into the limiting hole 5 again. The distance between the two arc tubes 11 can be changed through this device, so that tree trunks of different thicknesses can be well painted.

[0023] Specific working principle: when in use, the staff can hold the push rod 22 and move the device to the vicinity of the tree trunk to be painted, and then hold the handle 9 and pull the cross plate 6 upwards to stretch the spring 7 and drive the limit rod 8 to leave the limit hole 5, and then pull the slide plate 4 in the slide groove 3 to make the slide plate 4 slide in the slide groove 3. The movement of the slide plate 4 can drive the fixed plate 10 and the arc tube 11 to move, thereby changing the distance between the two arc tubes 11, and moving the device so that the tree trunk is located on the inner side of the two arc tubes 11, and moving the slide plate 4 again to move the slide plate 4 to a suitable distance, stop pulling the handle 9, and make the cross plate 6 move downward under the elastic force of the spring 7 until the limit rod 8 is inserted into the limit hole 5 again to limit and fix the slide plate 4. The two can be changed through this device. The distance between the arc tubes 11 can be used to paint tree trunks of different thicknesses. Then the pressure pump 21 is started. The pressure pump 21 allows the paint in the paint box 18 to enter the arc tube 11 through the feed pipe 19 and the telescopic hose 20 and be sprayed out through the nozzle 12 and sprayed onto the tree trunk. At the same time, the motor 14 is started. The motor 14 can drive the threaded rod 15 to rotate. The rotation of the threaded rod 15 can drive the connecting block 17 to move. The connecting block 17 can move more stably under the limiting action of the limiting column 16, and the forward rotation of the motor 14 can drive the connecting block 17 to move upward, and the reverse rotation of the motor 14 can drive the connecting block 17 to move downward. The movement of the connecting block 17 can indirectly drive the arc tube 11 to move. During the movement, the arc tube 11 can push the tree trunk well for spraying.
