Automatic spraying device for lime washing of trunk

Abstract

The invention discloses an automatic spraying device for lime washing of a trunk. The device comprises a frame traveling mechanism, an upright opening-closing mechanism, three sprayer clamp positioning mechanisms, three sprayer clamp up-down moving mechanisms and a hydraulic spraying mechanism, wherein the upright opening-closing mechanism is arranged on the left, middle and right parts of the frame traveling mechanism; the three sprayer clamp positioning mechanisms and the three prayer clamp up-down moving mechanisms are all arranged on the upright opening-closing mechanism; and the hydraulic spraying mechanism, an electronic control mechanism and an auxiliary mechanism are all arranged on the frame traveling mechanism. According to the automatic spraying device, a manual spraying mode is changed to an automatic spraying mode, and the sprayer clamp positioning mechanisms are used for ensuring that a proper distance is kept between sprayers and the trunk and simultaneously ensuring the centering requirement of the sprayers and the trunk when the diameter of a tree is changed; and the upright opening-closing mechanism is used for enabling the sprayer clamp positioning mechanisms to enclose a circle and enabling the sprayers to be uniformly distributed at the periphery of the trunk, so that the spraying quality is ensured, the utilization rate of paint is increased, the spraying stability is improved, and the trunk lime washing work is high in efficiency and stable.

Description

technical field [0001] The invention relates to a tree trunk whitening device, in particular to an automatic spraying device for tree trunk whitening. Background technique [0002] There are many kinds of trees in our country, and the number is huge. The annual whitewashing of tree trunks is a time-consuming and laborious work. At present, this heavy work is usually done manually. The manpower and material resources required to whiten the trees every year are not a small expense, and the staff need to do a lot of repetitive work. The manual whitening work is cumbersome and the work efficiency is low. , the labor intensity is high; and when manually whitening the trunk, the quality of the whitening cannot be unified, resulting in inconspicuous work effects. [0003] A new type of tree whitening machine applied by Zhejiang University of Technology, patent number ZL201110045745, which uses the method of "moving up and down, brushing while painting" to realize the whitening of ...

AI Technical Summary

Problems solved by technology

The nozzle of the machine is calibrated with a through-beam sensor, but the working conditions of tree trunk whitening are complicated, and electronic components are easily disturbed by external conditions, and the reliability is low; the spraying mechanism uses guide wheels to control the distance of the nozzle frame, but it is manually controlled, which wastes manpower ; The circular spraying area surrounded by the nozzle cannot achieve an effective spraying effect near the outside; there are no effective measures to ensure that the center of the tree being sprayed coincides with the center of the spraying area, so that the spraying effect is uniform
