Problems solved by technology

[0002] Most of the existing common digging machines are simple engines directly connected to a large-diameter auger. The engine drives the auger to rotate and dig downwards. The working tool is completely exposed. Although the excavation speed is fast, it is extremely dangerous and often jams. The knife machine can't stop the situation of hurting people, and one type of auger can only dig tree pits with a fixed size and depth. Replacing the auger is time-consuming and laborious and requires multiple sets of augers for replacement. If the auger is too large, the engine cannot be driven. Therefore, it is difficult to adapt to the application scenario of tree pit size transformation

Embodiment Construction

[0024] In order to make those skilled in the art better understand the technical scheme of the present invention, the present invention will be further described below in conjunction with embodiment:

[0025] A portable variable-diameter surround digging machine, including a support frame 1, the two ends of the support frame 1 are respectively connected with working handles 2, and the middle part of the support frame 1 is equipped with a speed-changing and diameter-changing mechanism 3. Both sides of the bottom of the variable-diameter mechanism 3 are respectively connected with a power distribution mechanism 4 and a direction-changing conveying mechanism 5. The variable-speed and variable-diameter mechanism 3 is connected with a variable-diameter gear rod 6, and the four corners of the support frame 1 are respectively movably connected with The fixed pin 7 of the support frame; wherein:

[0026] The variable speed and variable diameter mechanism 3 includes a main frame 31, an...

Abstract

The invention discloses a portable variable-diameter surrounding digging machine. The digging machine comprises a supporting frame, the two ends of the supporting frame are each connected with a working handle, and a variable-speed variable-diameter mechanism is erected in the middle of the supporting frame; the two sides of the bottom of the variable-speed variable-diameter mechanism are connected with a power distribution mechanism and a variable-direction conveying mechanism respectively; the variable-speed variable-diameter mechanism is connected with a variable-diameter gear rod; the fourcorners of the supporting frame are movably connected with fixing pins perpendicular to the supporting frame. The novel variable-diameter digging equipment is disclosed, is reasonable in structure and convenient to control, and is high in adaptability to variable-diameter digging of pits in different sizes. The safety is high due to a hidden cutter. The machine is a conveying type, so that soil discharge and covering are quick.

Description

technical field [0001] The invention relates to the technical field of tree planting and digging machinery, in particular to a portable variable-diameter surround digging machine. Background technique [0002] Most of the existing common digging machines are simple engines directly connected to a large-diameter auger. The engine drives the auger to rotate and dig downwards. The working tool is completely exposed. Although the excavation speed is fast, it is extremely dangerous and often jams. The knife machine can't stop the situation of hurting people, and one type of auger can only dig tree pits with a fixed size and depth. Replacing the auger is time-consuming and laborious and requires multiple sets of augers for replacement. If the auger is too large, the engine cannot be driven. Therefore, it is difficult to adapt to the application scenario of tree pit size change. Contents of the invention [0003] For this reason, the present invention proposes a double-saw blade...
