Rotary tree mover and tree moving method thereof

Abstract

The invention discloses a rotary tree mover which comprises a mover head device, a rotary support and a mover body. The rotary tree mover comprises a first rotation device driving the mover head device to rotate around a rotary support, a thrust device driving the rotary support to move close to or away from the mover body, a second rotating device driving the thrust device to rotate around the mover body and a lifting device driving the mover head device to life. By combining the rotary freedom degree of the mover head device with respect to the rotary support, the freedom degree of the thrust device driving the rotary support to move, the rotary freedom degree of the thrust device with respect to the mover body and the freedom degree of the lifting device driving the mover head device toperform vertical motion, the rotary tree mover can adjust the planned tree root cutting path of a cutter and the depth of the cutter entering a soil layer under the setting and control of a control system operating interface and facilitates safe, efficient, quick, convenient and high-quality spherical digging and transplanting operation conducted on different types and specifications of tress, and the adaptability of the rotary tree mover is improved.

Description

technical field [0001] The invention relates to the field of tree transplantation, in particular to a rotary tree digging machine and a tree digging method thereof. Background technique [0002] Urban greening, road greening, and garden landscape construction require a large number of trees every year. Most of the trees needed come from garden nurseries. In my country, there are currently tens of thousands of garden nursery companies that mainly plant (plant) landscape trees with seedlings. Among them More than 60% of enterprises start cultivating from seedlings in order to reduce costs and save expenses, and then dig up and sell grown trees according to user requirements, and replant trees in vacant land in time, carrying out a virtuous circle. Trees planted at the seedling stage have been grown and sold after about 5-15 years of cultivation. This planting method is called "primary (seedling) trees" in the industry, and some nursery companies purchase basically grown trees fr...

Problems solved by technology

[0003]Mechanical digging of trees is a transplanting method that has only appeared in the past five years. Before that, it has been completed manually using traditional tools such as picks and shovels for decades. The labor intensity is high, the operation time is long, the production cost is high, and the survival rate of transplantation has also been affected to varying degrees. Therefore, China's first "portable tree digging machine" came into being in 2012 and was widely used. Under the influence of this enterprise, foreign large and medium-sized tree transplanting equipment and technology have entered the Chinese market and manufacturing enterprises. Now it has formed a market situation in which more than a hundred enterprises compete with each other. However, the tree digging equipment produced by these enterprises has a common weakness. One is the large size. In order to save money and make full use of the nursery land for many years, the nursery enterprises in our country generally have a distance of 1.2-1.5 meters between trees with a height of about 1.5 meters, and a distance of about 1.5-2.5 meters between trees with a height of 2 meters. The spacing is even narrower, and buyers rarely purchase trees from Western countries in bulk. Instead, they go to the nursery to select and mark trees one by one. Because the spacing between trees is too small and drainage ditches are criss-crossed, and large-scale machinery cannot Inaccessible for tree digging, therefore extremely low utilization

[0004] Up to now, although "portable" tree digging equipment at home and abroad has high efficiency, its labor intensity is relatively high. The tree forms mainly include: 1. The tree digging method disclosed in a horizontal milling tree digging machine with the application number 201510263464.6 through 3-4 plum petal digging knives driven by hydraulic cylinders; 2. A tree digging method with the application number 201710027061.0 A method of digging trees by pulling soil and roots through a saw chain disclosed in a crawler tree digging machine; 3. A method of digging trees with a semicircular arc rotary cutter in a saw chain tree digging machine with application number 201320576770.1; 4. Two pieces of semi-cylindrical down-cutting type; four methods, practice has proved that they have good tree digging efficiency and quality when transplanting (seedling) trees, but the tree that often appears when transplanting native (seedling) trees is digging trees When the root diameter is more than 5 cm, there is nothing that can be done. Even if the hard operation is not to destroy the soil ball, the root with a diameter of 3-8 cm will be squeezed or broken horizontally. The broken or broken section will not only crack but also The soil around the section and the fibrous roots entrained by the soil that are responsible for absorbing nutrients will fall off. This kind of cracked section is easy to breed bacteria, which will not only seriously affect and damage the later growth of transplanted trees, but also cause leaves to fall after transplanting. , dry or dead, for trees whose lateral root diameter is 8, 10, 15, 20 cm or larger, we can only avoid and not dig

[0005]Existing tree diggers generally excavate trees with one or more excavation paths and excavation depths that have been set during the design and manufacture of the machine. However, this operation method is difficult to meet the actual requirements of soil ball specifications for different regions, different soil and geographical conditions, different tree species, and different specifications of trees, and it cannot be limited according to the different growth conditions of trees in various places and the actual operating site of the nursery. etc. to make effective adjustments, so that the function of the tree digger is single, and the adaptability to different tree digging requirements and tree digging site constraints is not enough. Difficulty, and affect the transportation and transplantation of subsequent trees, and more seriously, it is powerless for larger native trees
