Description
Technical Field
The invention relates to the technical field of municipal tree painting, in particular to a trunk painting device for municipal engineering.
Background
The municipal works refer to municipal facility construction works, which include maintenance of trees near urban roads. Typically, municipal trunks are brushed white. The white paint on the tree trunk is lime water mixed by quick lime, and the tree is brushed with the lime water. There are several benefits: first, lime has certain bactericidal and insecticidal effects. Some of the overwintering fungi, bacteria and pests that are parasitic on the trunk can be killed. Secondly, pests generally prefer black, dirty areas. A white, clean place is not preferred. The trunk is coated with snow-white lime water. The pests wrapped in the soil are not dare to climb onto the tree along the trunk to gnaw the tree. Thirdly, in winter. The temperature in the night is very low; it is time to day. When the tree is irradiated by sunlight, the temperature rises, and the tree trunk is dark brown, so that the tree trunk can easily absorb heat. The temperature of the trunk also rises quickly, so that the trunk is easy to frost crack due to cold and heat, and particularly, the trunk is thick, the color is deep, the tissue toughness is poor, and the trunk is easy to crack. After the lime water is coated, 40% -70% of sunlight can be reflected because the lime is white, so that the trunk is not easy to crack because the temperature difference between day and night is not large. At present, the tree is generally coated with lime water manually, so that the labor intensity of workers is high, the coating efficiency is low, and the trunk coating device for municipal greening, which can reduce the labor intensity of the workers, can improve the coating efficiency, is simple to operate and is convenient to use, needs to be researched and developed urgently.
In actual construction, roadside trees, especially trees on two sides of a long road, generally have large difference in upper and lower diameters, especially large trees with a diameter of one meter or two meters, the larger difference in the upper and lower diameters may cause bending deformation, or a trunk may be damaged by insect pests in the growing process of the trunk in a month, and the trunk surface is not flat and has gullies. (the upper and lower diameters have difference, the trunk is bent and inclined, the tree surface has gully, and the section of the trunk is not necessarily round)
In the prior art, most of the coating materials are manually brushed, so that the efficiency is low, the quality is low, the coating materials are brushed in different thicknesses, the labor capacity is large, and the coating materials are wasted; small parts are coated by instruments, such as patent documents with application numbers of cn201910602879.x, CN201810002151.9, CN201711410491.7, CN201710655745.5 and CN201711410460.1, and the solutions proposed in these documents have obvious defects:
1. the diameter of the painting structure is fixed and cannot adapt to trees with different diameters, the diameter of the upper end of the trunk is smaller than that of the lower end of the trunk, the structures are likely to cause that the distance between the spray head and the surface skin of the tree is too large in the places with small diameter of the sprayed trunk, the paint is sprayed around, waste is caused, the surrounding environment is also influenced, the spray head is possibly clamped by the surface of the tree in the places with large diameter, and construction cannot be continued;
2. the path of the painting structure is up and down moved in the vertical direction by default, but the fact is that the upright rod 16 is inclined, and also bent and deformed, and the painting structure can be blocked;
3. the spraying range of the spraying nozzle is fan-shaped, the spraying nozzles in the structures can only move up and down, the spraying path is fixed, the range is limited, if a plurality of gullies exist on the trunk, large dead angles exist in the spraying area of the spraying nozzle, and the dead angles are the favorite places of insects, so the effect is not good.
4. Most of the tree scars and the keloids are odd in shape, the tree scars are mostly in a necking shape, namely, the opening is smaller than the internal space of the tree scars, the existing painting and brushing mechanism easily omits the dead angle in the tree scars, leaves living space for insects and is not beneficial to the health of trees.

When in specific use, the handle 1 is held by hand and the spraying device 2 presenting an arc shape is buckled on a tree, the power supply of the high-pressure pump is switched on, at the moment, the coating is sprayed to the tree surface outwards through the spray head 7, the handle 1 is held by hand and the device is moved up and down along the tree surface, the wheels 13 roll on the tree surface, wherein the wheel 13 drives the first chain wheel 18 to rotate through the second chain wheel 19, so as to realize the rotation of the cylindrical cam 14, the cylindrical cam 14 rotates and drives the whole toothed chain to reciprocate along the slide rail through the upright rod 16, the toothed chain reciprocates and drives the gear 9 to rotate, the gear 9 rotates and drives the end cover 6 to rotate through the rotating shaft 8, finally, the spray head 7 on the end cover 6 reciprocates, when reaching the tree root, the power supply of the high-pressure pump is disconnected, then an angle is changed, and repeating the operation on the other angle of the trunk until the whole upright stanchion 16 is sprayed all around, and finishing the painting of one trunk at the moment to prepare for the painting of the next trunk.
The invention has the outstanding advantages and remarkable progress that:
1. a plurality of small spraying units 3 are hinged through torsion springs in the device, can be well attached to the surface of a tree surface, and the control spray head 7 which can be fine like the device can reduce waste as much as possible according to the tree trunks which are fine in practical condition and adapt to different diameters, and does not have the risk of being stuck.
2, as the distance between the spray head 7 and the bark is kept stable basically, the spray range and the thickness of the spray head 7 sprayed on the vertical shaft are consistent basically, and the painting is more uniform.
3. The spray head 7 swings left and right in the vertical movement process of the whole device, and particularly can spray paint into ravines of a tree surface, contracted tree scars and protruded tree knots on the tree surface, so that the dead angle range is reduced, and comprehensive spraying is carried out.
4. The invention has wider application range and can also be brushed on trees with extremely small diameter, and the concrete operations are as follows: the brushing device in the device is straightened into a straight line and is placed along the axial direction of the upright rod 16, then the handle is held by hand and the brushing is carried out around the trunk during the brushing, and the brushing operation of the trunk with the smaller diameter can be completed by repeating the steps. In addition, the device can also be applied to wall painting operation and various operations in various fields.
