Description
Technical field
The invention belongs to power tools technology fields, and in particular to a kind of trunk whitewashes equipment automatically.
Background technology
Trunk whitewashing refers to that trunk has been brushed one layer of white liquid upwards by bottom.The advantages of trunk whitewashing major embodiment
In following several respects：
1, it sterilizes, prevent germ from infecting, and accelerating wound healing；
2, desinsection, insect prevention.It kills and sets intracutaneous overwintering worm's ovum and the dry insect of moth.Since pest generally all likes black, dirty
Dirty place does not like white, clean place.Trunk has coated snow-white limewash, and the pest in soil just dare not be along
Trunk is climbed to makes trouble on tree, can also prevent bark by animal bite；
3, frost damage prevention and day burn, and avoid early spring frostbite.In winter, night, temperature was very low；To daytime, shone by sunlight
It penetrates, temperature increases, and trunk is dark brown, is easy to absorb heat, stem temperature also rises quickly.So cold heat, makes
Trunk is easy bursting by freezing.Especially big tree, trunk is thick, and color is deep, and organizes toughness again poor, it is easier to split.Stone is applied
After buck, since lime is white, the sunlight of 40%-70% can be made to be reflected, therefore trunk is in the temperature on daytime and night
Degree is not much different, and is just not easy to split.Postpone fruit tree bud and florescence, prevents early spring frostbite；
4, facilitate night walking along the street, after trees brush is at white, reflective, the pedestrian at night of meeting can see road more clear
Chu, and beautification function is played, give a kind of very neat feeling of people.
In the prior art, trunk whitewashing is all made of the mode manually brushed and completes, and when whitewashing operation, gardener one is portable
Storage vat, a hand-held brush carry out brushing operation according to certain requirement.Following principle should be followed when whitewashing：Isolation strip
Shade tree uniformly whitewashes 1.2-1.5 meters of height, other to be carried out by 1.2m requirements, and same a road section, whitewashing for region should highly keep
Unanimously, achieve the effect that neat appearance.It is dilute appropriate to be done when masking liquid, to repeat to brush to bark gap, hole, crotch etc.,
Avoid brushing be lost in, the leakage of brush flower brush, it is dry after fall off.It should be carried out after rainy season in time of the year when autumn changes into winter every year, preferably early spring applies once again, effect
Fruit is more preferable.It can be seen that traditional operation of whitewashing haves the shortcomings that labor intensity is big, working efficiency is low and whitewashes ineffective.
