Description

An adjustable rotating support device for tree pruning

Technical field

The present invention relates to the technical field of garden work tools, and in particular, to an adjustable rotating support device for tree pruning.

Background technique

In the construction of urban landscaping, full-crown transplanted seedlings play an important role in improving the urban ecological environment because of their large grass blade area, large amount of greening, and considerable ecological benefits. There are many problems in the current large seedling transplantation technology: mainly the survival rate is low, the pruning intensity is too high (generally requires 2 to 3 years of recovery period), the recovery after survival is slow, a waste of resources, a waste of people and money; the ecological effect cannot be exerted immediately, and the ecological effect cannot be achieved immediately. Ideal landscape effect. Full-crown transplantation of large-sized (diameter at breast height 10cm or more) seedlings refers to transplanting trees that grow naturally in the same place while retaining the original crown branches, leaves and shape. This method has been very successful in transplanting small-sized individual varieties, but it can generally only be done in spring. When the tree is large, the crown width should not be too large. Small-sized seedlings transplanted with full crowns will not achieve the ideal landscape effect in the garden. For tree species with strong seasonal requirements, it is also possible to prepare them a year in advance or longer, or to use container seedlings or fake planting for a certain period of time before transplanting.

Principles of tree survival Whether a tree can survive is related to many factors, including the growth habits of plants. The basic principles of tree transplantation survival mainly include the principle of approximate habitat and the principle of tree vigor balance. The principle of approximate habitat means that the environment after transplantation is similar to the ecological environment before the plant was transplanted, including sunlight, rainfall, temperature, soil conditions, etc. The green ecological environment is a comprehensive whole, and changes in any factor may seriously affect the survival rate of transplanted Qiao Da. Therefore, the ecological environment after transplantation should be as similar as possible to that before transplantation. If necessary, the soil conditions of the trees to be transplanted should be improved to facilitate the survival of the trees. Tree balance refers to the balance between the above-ground and underground parts of the tree, so that the underground and above-ground parts of the tree maintain consistent growth conditions.

Before transplanting a tree, the large branches and leaves of the transplanted tree should be pruned. Dead branches, branches damaged during transportation, etc. should be removed according to greening requirements. In order to keep the shape of the tree crown intact and ensure the supply of water and Consumption balance. The extent of pruning depends on the regeneration ability of different tree species. For deciduous trees, the pruning amplitude can be larger, and those with fast growth speed and strong regeneration ability should also be used.

At present, when pruning an arbor, a support device is usually installed to support the trunk of the arbor to facilitate pruning of branches. The traditional support device is an X-shaped bracket formed by cross-tied wooden roots. Although it is simple to make, due to the large differences in the growth sizes of the trunks and branches of trees of different ages, the traditional support bracket cannot adjust the height according to the size of the tree. The adjustment of the support end is less practical; the improved support frame is connected by rotation at the intersection and connected through the limit rod. By changing the angle of the intersection and the connection position of the limit rod, the overall support of the support frame can be changed. The height and the snap-on size of the support part are small, but the adjustment space is limited and precise adjustment cannot be achieved, and the adjustment operation is cumbersome and difficult to achieve.
