Description

Technical Field

[0001] The utility model belongs to the technical field of roadside tree maintenance, and particularly relates to a roadside tree maintenance device. Background Art

[0002] Street trees refer to trees planted on both sides of roads and dividing strips, which have certain shading functions, guiding functions and landscape effects.

[0003] Whitewashing is one of the maintenance tasks for street trees. It requires applying lime water on the branches of street trees. Whitewashing can reduce diseases and pests of street trees, reduce the heat generated by direct sunlight, and reduce the occurrence of frost damage.

[0004] Existing whitewashing operations are usually done manually or using tree whitewashing machines. Manual whitewashing wastes manpower, and workers come into close contact with lime water, which can easily be inhaled and cause pneumonia. Existing tree whitewashing machines spray lime water on trees through nozzles, which can easily cause the lime water suspension to float and cause harm to the human body.

[0005] Although the existing tree whitewashing machine has a certain adjustment capability, when the tree trunk is too thick, it may not be able to be installed on the outside of the trunk, resulting in the inability to whitewash and maintain the tree. Utility Model Content

[0006] The purpose of the present utility model is to solve the problems described in the above background technology that lime water is easily inhaled by the human body during whitewashing maintenance of street trees, affecting the health of workers and the limited regulatory ability. A new street tree maintenance device is proposed, which can prevent the dispersion of lime water suspension and can adapt to whitewashing operations on street trees of various sizes.

[0007] A technical solution adopted to achieve the above-mentioned purpose is a street tree maintenance device, which includes a liquid storage tank, a connecting pipe, a handle, a connecting piece and a spray unit. The handle is hollow inside and a micro pump is provided in the handle. One end of the connecting pipe is connected to the liquid storage tank, and the other end of the connecting pipe passes through the handle and is connected to the liquid inlet of the micro pump. The spray unit includes a liquid infusion main pipe, a plurality of connecting pieces, a plurality of nozzles, a flexible piece, a protective cover, a first connecting part and a second connecting part. The protective cover is arranged on the outside of the flexible piece, and the liquid infusion main pipe is arranged between the flexible piece and the protective cover. One end of the connecting piece is connected to the liquid infusion main pipe, and the other end of the connecting piece passes through the protective cover. The nozzle is connected to the other end of the connecting piece. The first connecting part and the second connecting part are detachably connected. The liquid outlet of the micro pump is connected to the liquid infusion main pipe through a pipeline, and the connecting piece connects the handle and the flexible piece.

[0008] In the above technical solution, the lime water suspension in the liquid storage tank is extracted by a micro pump and passed into the spraying unit for whitewashing. The flexible part can be bent and deformed but has a certain rigidity. The flexible part is connected by the first connecting part and the second connecting part, and the flexible part is bent into a ring shape, so that the street trees are whitewashed and maintained.

[0009] Furthermore, the first connecting portion is a plurality of buckles, and the second connecting portion is a plurality of buckle seats, and the buckles are engaged with the buckle seats.

[0010] Furthermore, the buckle and the buckle seat are staggered and fixed on both sides of the protective cover.

[0011] In the above technical solution, the size of the ring formed by the bending of the flexible member can be adjusted by adjusting the position of the buckle corresponding to the buckle seat, so as to adapt to street trees of different thicknesses.

[0012] Furthermore, the flexible member is arched, and the main infusion pipe is located directly below the flexible member.

[0013] In the above technical solution, due to the arched structure, when spraying lime water, it can act as a cover to block the scattered lime water suspension to a certain extent.

[0014] Furthermore, the handle is provided with a button, and the button is electrically connected to the micro pump.

[0015] In the above technical solution, the micro pump can be controlled by buttons, which is convenient for staff to operate.

[0016] Furthermore, a shoulder strap is provided on one side of the liquid storage tank.

[0017] In the above technical solution, workers can carry the liquid storage tank on their backs to facilitate operations.

[0018] Furthermore, the flexible member is made of memory metal.

[0019] In the above technical solution, the flexible member can be pressed so that it bends and rolls naturally, thereby reducing the space occupied by the device.

[0020] Furthermore, the plurality of connecting pieces are arranged at even intervals.

[0021] In the above technical solution, the whitening is made uniform by arranging the layers at even intervals.

[0022] Furthermore, the spraying unit also includes a plurality of elastic washers, which are fixedly connected to the protective sleeve and are sleeved on the outside of the spray head.

[0023] In the above technical solution, the nozzle can be protected by an elastic gasket to prevent damage due to bumps.

[0024] The advantages of the present invention are:

[0025] 1. The utility model blocks and collects the scattered lime water suspension by setting an arched flexible part, thereby reducing the impact of lime water on the health of workers.

[0026] 2. The utility model uses flexible parts with certain rigidity and flexibility to be combined and fixed to form a ring to surround the street trees, which can adapt to thicker street trees.

[0027] 3. The utility model can automatically reel in the flexible part by pressing it, thereby reducing the space occupied by the device. BRIEF DESCRIPTION OF THE DRAWINGS
