[0002] As people's living standards improve, they pay more and more attention to the environment. In municipal greening projects, in environmental protection, in order to ensure the normal growth of trees, it is necessary to carry out insect prevention operations on seedlings during the growth of trees. Generally, greening trees are painted with lime water. Painting with lime water can prevent plants from being attacked by longhorn beetles, and the trunks will not be frozen and cracked due to the huge temperature difference between day and night. It also has the effect of sterilization and insect prevention. Therefore, painting equipment is needed to paint them.

[0003] However, the existing tree brushing device cannot adjust the brush head according to the diameter of different trees when in use, so it is not practical and needs to be brushed manually, which increases the labor intensity and greatly reduces the work efficiency. Utility Model Content

[0006] The side walls of the inner circle sides of the two arc-shaped support frames are provided with arc grooves, and a brush belt is arranged inside each of the arc-shaped support frames. A tension spring is fixedly connected to the middle position of the two brush belts away from each other on one side, and the other end of the tension spring is fixedly connected to the inner wall of the adjacent arc groove;

[0007] Two springs are arranged inside each of the arc grooves, and the two springs inside each arc groove are respectively located at the two ends thereof, and the adjacent ends of two adjacent springs are fixedly connected with support blocks, and the top and bottom of each support block are rotatably connected with support rollers via a rotating shaft, and the rotating shaft is rotatably plugged into the support block, and the support roller is rotatably sleeved on the end of the rotating shaft away from the support block, and the support roller contacts the side wall of the brush belt.

[0008] Preferably, a fixing block is fixedly connected to the inner wall of the arc groove at a position corresponding to the spring, and one end of the spring away from the supporting block is fixedly connected to the fixing block.

[0009] Preferably, one end of the support block close to the spring is fixedly connected with a fixed shaft, and the fixed shaft is inserted into the interior of the spring.

[0010] Preferably, the rotating shaft passes through one end of the supporting roller and is fixedly connected to a limiting disk.

[0011] Compared with the prior art, the utility model has the following beneficial effects: the utility model is a tree paint brush for municipal greening, which has a simple structure and is easy to use. Brush belts are arranged inside two arc-shaped support frames for soaking lime water. The tension spring arranged on the outer wall in the middle position of the brush belt can stretch it and cooperate with the springs arranged on both sides to push the support rollers to resist and support it, so that when the brush belt is located inside the arc-shaped support frame, it can freely cover the outer wall of the tree according to the diameter of the tree, so that it can automatically adjust according to the diameter of the tree, and can efficiently paint the tree.

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. 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.

[0019] See also Figure 1-5 The utility model provides a technical solution: a tree brush for municipal greening, comprising two arc-shaped support frames 1, the outer walls of one end of the two arc-shaped support frames 1 are fixedly connected with hinge blocks 2, and the two hinge blocks 2 are hinged by a pin shaft 3;

[0020] The side walls of the inner circle of the two arc-shaped support frames 1 are provided with arc grooves 5, and a brush belt 7 is provided inside each arc-shaped support frame 1. A tension spring 8 is fixedly connected to the middle position of the two brush belts 7 away from each other, and the other end of the tension spring 8 is fixedly connected to the inner wall of the adjacent arc groove 5;

[0021] Two springs 9 are provided inside each arc groove 5, and the two springs 9 inside each arc groove 5 are respectively located at the two ends thereof, and the adjacent ends of two adjacent springs 9 are fixedly connected with support blocks 10, and the top and bottom of each support block 10 are rotatably connected with support rollers 13 through a rotating shaft 12, the rotating shaft 12 is rotatably plugged into the support block 10, and the support roller 13 is rotatably sleeved on the end of the rotating shaft 12 away from the support block 10, and the support roller 13 is in contact with the side wall of the brush belt 7.

[0022] A fixing block 6 is fixedly connected to the position of the spring 9 on the inner wall of the arc groove 5, and the end of the spring 9 away from the support block 10 is fixedly connected to the fixing block 6.
