Trunk whitening automatic spraying device

Abstract

The invention discloses an automatic spraying device for whitening tree trunks, comprising: a vehicle frame traveling mechanism, a column opening and closing mechanism, a positioning mechanism for three nozzle clips, a mechanism for moving up and down three nozzle clips, a hydraulic spraying mechanism, etc.; wherein, the column opening and closing mechanism The left, middle and right are respectively installed on the traveling mechanism of the vehicle frame. The positioning mechanism of the nozzle clamp and the up and down movement mechanism of the nozzle clamp are installed on the opening and closing mechanism of the column; the hydraulic spraying mechanism, the electric control mechanism and the auxiliary mechanism are all installed on the traveling mechanism of the vehicle frame; The present invention changes manual brushing into automatic spraying, and uses the nozzle clamp positioning mechanism to ensure a proper distance between the nozzle and the trunk, and at the same time ensures the neutrality of the nozzle and the trunk when the diameter of the tree changes; uses the column to open and close The mechanism makes the nozzle clamp positioning mechanism form a circle, and makes the nozzles evenly distributed on the periphery of the trunk; thus ensuring the quality of spraying, improving the utilization rate of paint, improving the stability of spraying, and making the trunk whitening work efficient and stable.

Description

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

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
