Description

Technical Field

[0001] The invention belongs to the field of garden machinery and in particular relates to a tree trunk whitening machine which can adjust the spraying direction according to the diameter of the tree trunk to change the spraying flow rate. Background Art

[0002] Whitewashing of tree trunks plays an important role in protecting trees and beautifying the environment. For trees with different trunk diameters, the spraying direction cannot be controlled to change the spraying flow rate. At the same time, most trunk whitewashing machines used for road whitewashing require manual aiming at the trunks for spraying. When there are uneven road surfaces beside the road, the trunk whitewashing machine needs to be manually pushed to the high-step road surface for work, which is very inconvenient.

For example, the patent document with patent number CN118454925A and publication date August 9, 2024, when the spraying component of the equipment is working, the electric push rod pulls the bracket to surround the tree trunk. For trees with different trunk diameters, the gap between the nozzle and the trunk is different, which easily causes waste of whitewashing agent. Summary of the invention

[0153] Working principle: When the trunk whitening machine starts working, the reduction motor under the frame starts to drive the wheels to move forward. When the trunk of a greening tree is identified, the platform telescopic device 30 of the trunk whitening machine faces the trunk of the greening tree, and the trunk whitening machine stops. At the same time, the stepper motor under the base plate 3001 starts working, driving the No. 2 screw to rotate through the coupling 2003. At this time, the screw nut on the No. 2 screw starts to drive the base plate 3001 fixed on the screw nut bracket to extend forward, and the slider 3002 fixed on the base plate 3001 assists the base plate 3001 to extend outward on the guide rail 3003. At the same time, the double-bearing auxiliary pulley fixed on the frame also plays an auxiliary and supporting role, which can make the entire device above the base plate 3001 extend outward smoothly. Further, the dual-axis steering gear 1010 on the No. 4 bracket 1004 starts to work, opens the entire bracket, and the entire platform telescopic device 30 continues to extend outward. Then, the ultrasonic sensor 1009 above the No. 5 bracket 1005 emits a signal. At this time, the V-shaped nozzle 1007 on the No. 5 bracket 1005 is at a suitable distance from the tree trunk, and the stepper motor under the bottom plate 3001 stops working. Further, the adaptive spraying device 10 accurately controls the angle according to the trunks of greening trees with different diameters by the steering gears on the No. 4 bracket 1004 and the No. 2 bracket 1002. When receiving the signal from the collision sensor 1006 on the No. 1 bracket 1001, the steering gear stops working. At this time, all V-shaped nozzles 1007 are at a suitable distance from the tree trunk. At the same time, the water pump starts to work, and the whitening agent is sucked from the spray box by the suction pipe, and then the whitening agent is transported by the delivery pipe connected to the nozzle to start the whitening work. Furthermore, for tree trunks with different degrees of curvature, the angle of the V-shaped nozzle 1007 is adjusted in time by receiving the signal from the collision sensor 1006 on the No. 1 bracket 1001 in real time, so as to adjust the spraying direction, reduce the spraying flow rate, and complete the whitewashing of the tree trunk. Furthermore, the stepper motor above the bracket of the lifting device 20 starts to work, and drives the No. 1 screw 205 to rotate through the coupling 2003. At this time, the screw nut on the No. 2 screw starts to drive the clamping claw bracket fixed on the screw nut bracket to start to descend, and at the same time drives the adaptive spraying device 10 to start lifting and lowering to perform the whitewashing work. When the whitewashing work is completed, the whitewashing work of the next tree is repeated. Furthermore, when the whitewashing work is completed, the servo controls each bracket to open, and at the same time, the stepper motor under the base plate 3001 starts to work, driving the second screw to rotate through the coupling 2003. At this time, the screw nut on the second screw starts to drive the base plate 3001 fixed on the screw nut bracket to shrink inward, and the slider 3002 fixed on the base plate 3001 assists the base plate 3001 to shrink inward on the guide rail 3003, and then continues to repeat the whitewashing work of the next tree.
