Description
Technical field
The present invention relates to forestry machinery field, specifically a kind of lumbering assists pulling attachment with tree root.
Background technique
In existing lumbering construction, trees can leave stub after breaking apart by chopping, and the conventional method for removing stub is incited somebody to action with excavator
It digs out, but the place poor in terrain environment, such as on steep hills slope, excavator is difficult to pass through, and manpower work can only be leaned on to dig
Out, if ignoring what stub was abandoned, the natural reparation of soil is not only influenced, but also will cause the waste of resource, and is dug by hand at present
The tool for taking tree root is still traditional agricultural tool, such as axe, draft, plane fork, not only wastes time, also wastes very energetically
Gas, nowadays high mechanization, this traditional tool are obviously not suitable with various industries, it is therefore desirable to which one kind is exclusively used in digging
The manual machinery of tree root, to cope with the environment that big machinery can not work.
Summary of the invention
For the problems of the prior art, the present invention provides a kind of lumbering tree roots to assist pulling attachment, can dig
Complex environment region that pick machine can not reach uses, and is not necessarily to electric power or fuel oil, can directly install and be operated by hand, and compared with
Operating is realized in the case of small artificial force.
The technical solution adopted by the present invention to solve the technical problems is: a kind of lumbering tree root auxiliary pulling attachment, packet
It includes support frame, the lifting apparatus for being lifted tree root height, support plate for connecting each mechanism, obtain for being punched on tree root
