Tree maintenance device for municipal engineering

Abstract

The invention belongs to the field of tree whitewashing, and particularly relates to a tree maintenance device for municipal engineering. The device comprises a straight guide sleeve, sliders, a circular groove A, a hose, a nozzle, a guide rail, a sliding sleeve and an arc guide sleeve, a plurality of sliding blocks are sequentially arranged in the straight guide sleeve in a sliding fit mode in the length direction of the straight guide sleeve, and sliding of the sliding blocks in the straight guide sleeve is manually driven; and every two adjacent sliding blocks are hinged to each other. According to the tree whitewashing device, the arc guide sleeve is used for guiding the sliding blocks which move towards the outside of the straight guide sleeve and are connected with one another to form a spraying ring surrounding a tree by one circle, compared with traditional manual tree whitewashing, the tree whitewashing device is high in whitewashing efficiency and whitewashing speed; meanwhile, repeated squatting and left-right repeated movement of an operator due to the change of the whitewashing height in manual whitewashing work are avoided, so that the physical loss in whitewashing engineering is reduced.

Description

technical field [0001] The invention belongs to the field of tree whitening, in particular to a tree maintenance device for municipal engineering. Background technique [0002] The trunks of urban gardens and trees all have to be coated with a layer of white, which is customarily called "painting white". Because in winter, the sunny side of the tree is irradiated by sunlight during the day, the temperature rises, the cells thaw, and the temperature drops at night, and they freeze again; After the tree is painted white, it not only wraps it with a layer of cold-proof skirt, but also increases the ability of the tree to reflect sunlight, so that the temperature of the trunk changes more stably, avoiding freezing during the day and night, reducing freezing damage, and preventing "sunburn". At the same time, white coating can also accelerate wound healing, prevent bacterial infection, and kill overwintering eggs in the bark, effectively preventing pests and diseases. [0003] ...

AI Technical Summary

Problems solved by technology

[0003] Traditional tree whitening work generally adopts artificial whitening method, that is, workers use a brush to dip the whitening agent to whiten the lower part of the tree trunk. The whitening speed is slow and the efficiency is low, the labor cost is high, and the whitening effect is inconsistent. There are good and bad

[0004] The public publication number "CN 110328070 A" "a kind of whitening equipment for tree trunks in municipal engineering" solves the problem of low efficiency and slow speed of traditional artificial whitening, and creates new problems

That is, in order to adapt to the whitening of trees of different thicknesses, the diameter of the annular part formed by the first arc-shaped block and the second arc-shaped block in "CN 110328070 A" "a kind of municipal engineering trunk whitening equipment" should be The maximum is large enough, which will lead to the increase of the mass of the ring part formed by the first arc block and the second arc block, and the increase of the force arm of the ring part relative to the handle, thus resulting in the ring part due to its own weight relative to the Increased torque at the grip for greater effort in whitening operations
