Problems solved by technology

When construction is carried out in densely wooded areas, the large and expensive mechanical trolley-type tree excavators are difficult to drive in and the space is insufficient, which is constrained and difficult to carry out
And the artificial tree digging machine is also relatively heavy and inconvenient to operate
Most of the existing tree diggers use the static pressure blade cutting method, which has high requirements on the soil and is difficult to implement when there are large stones

Embodiment 1

[0047] see Figure 1-7 , a portable tree digging machine, which includes a rotating ring 1 for being fixedly connected with a tree pole, a rotating arm 2 is symmetrically hinged on the outer side wall of the rotating ring 1, and the rotating ring 1 is used for driving it around. The power device 10 for the rotation of the tree rod is connected, and the other end of the rotating arm 2 is connected with a cutting device for cutting the soil.

[0048] Further, the rotating ring 1 adopts an assembleable split structure, the inner ring adopts a rubber washer 8, a bearing ring 9 is installed on the outer ring of the rubber washer 8, and the rubber washer 8 is in contact with the inner side wall of the tree rod. for the rough surface structure. The inner side of the rubber gasket 8 is rough, which can effectively fix the tree trunk and play a certain buffering role, so that the tree trunk will not be damaged due to mechanical rotation. Both the rubber gasket 8 and the bearing ring ...

Embodiment 2

[0059] like Figure 8-11 , a portable tree digging machine, which includes a fixed ring 4 for being fixedly connected with a tree pole, and a horizontal rod 5 with adjustable length is symmetrically installed on the outer side wall of the fixed ring 4, and the other end of the horizontal rod 5 A diagonal rod 6 is fixedly installed, the diagonal rod 6 is connected with a power device 10 for driving it to rotate around the horizontal rod 5, and the other end of the diagonal rod 6 is installed with a diamond wire saw 7 for cutting soil. . The power device 10 is arranged between the horizontal rod 5 and the oblique rod 6 instead of being connected to the support ring 24 of the tree trunk, which can effectively prevent the diamond wire saw 7 from generating a force couple on the tree through the support ring 24 when it rotates in the vertical plane, resulting in the entire system instability problem.

[0060] Further, the inner ring of the fixing ring 4 adopts a rubber washer 8, ...

Embodiment 3

[0073] like Figure 12 , the cutting device includes a hydraulic rod 38, the hydraulic rod 38 is connected with the bearing ring 9 of the rotating ring 1 through the rotating shaft 11, the hydraulic rod 38 can rotate in a vertical plane around the rotating shaft 11, the hydraulic rod The lower end of 38 is connected with the common curved sheet cutter 39 through a rotating rod 40, the rotating rod 40 is connected with the power device, and drives the common curved sheet cutter 39 to perform rotary excavation. Through the combined action of the rotation of the rotating shaft 11, the rotating rod 40 and the expansion and contraction of the hydraulic rod 38, the ordinary curved sheet knife 39 can perform rotary cutting around the tree trunk, and the cutting angle can be adjusted at any time during the cutting process. The blade avoids larger obstacles. Finally, after the ordinary curved sheet cutters are finished cutting, the two ordinary curved sheet cutters 39 are closed toget...

Abstract

The invention provides a portable tree mover. The portable tree mover includes a rotation ring for being fixedly connected with a trunk, rotation arms are symmetrically hinged to the outer side wall of the rotation ring, the rotation ring is connected with a power device for driving the rotation ring to rotate around the trunk, and a cutting device for cutting a soil body is connected to the other ends of the rotation arms. The portable tree mover is small and convenient to mount and dismount and can rapidly cut the soil and carry out soil seizing protection, and thus the effect of cutting and seizing the soil in one step is achieved.

Description

technical field [0001] The invention relates to the technical field of forestry machinery, in particular to a portable tree digger. Background technique [0002] In practical projects, mechanical trolleys or artificially supported tree diggers are mostly used for tree digging, but many difficulties will be encountered in the specific implementation. When the construction is carried out in the densely wooded area, the large and expensive mechanical trolley-type tree excavator is difficult to drive and the space is insufficient, which is constrained and difficult to implement. In addition, the manual tree excavator is also relatively cumbersome and inconvenient to operate. Most of the existing tree excavators use the method of cutting soil with static pressure blades, which requires high soil and is difficult to implement when there are large stones. SUMMARY OF THE INVENTION [0003] In order to solve the above technical problems, the present invention provides a portable ...
