Problems solved by technology

[0002] At present, many ornamental tree seedlings in landscaping are planted by means of transfer. In places with convenient roads, excavators will be used to dig holes. Usually, manual digging is generally used. In actual operation Laborious, low efficiency, high consumption, and the excavated tree pits are not standardized. Later, a manual screw type digging device appeared, and a manual rocker arm was used to dig a hole, but it was still very inconvenient and the digging efficiency was low. Most of the existing common digging machines are simple and directly connected to a large-diameter auger through the engine. The engine drives the auger to rotate and dig downward, but the working tool is completely exposed. Although the excavation speed is fast, it is dangerous and often jams. The knife machine can't stop hurting people, and one type of auger can only dig tree pits with a fixed size and depth. It is time-consuming and laborious to replace the auger, and multiple sets of augers are required for replacement, but the larger auger Digging pits requires higher power, and the power of the engine obviously cannot be effectively adapted, and the engine cannot be driven, so it is difficult to adapt to the application scene where the size of the tree pit changes. Although the excavation device that can be adjusted up and down is currently used, it still cannot be adjusted. The diameter of the excavation pit, and the use of unmanned aerial vehicles to excavate the pit, the above existing excavation methods are difficult to meet the needs of the actual excavation operation process

Abstract

The invention discloses a pit digging method of a portable diameter-variable surrounding pit digging machine. The method includes the steps that two operators lift the device to a position where pitsneed to be dug, and fixing pins are inserted into soil; an engine is started, a direction-variable conveying mechanism is returned to a zero point by pulling a diameter changing gear handle, a slidingpressing plate is moved, an accelerator is adjusted to start pit digging, and a minimum pit is formed after a main frame rotates for one circle under the action of a surrounding speed changing gear set; the diameter changing gear handle is pulled, the digging diameter can be enlarged in a running process, the main frame rotates for one circle under the action of the surrounding speed changing gear set, and after the second circle of digging is finished, similar operation is carried out until the required pit diameter is achieved through digging; operation is carried out progressively. Pits are continuously dug from the center to the periphery, so that the digging resistance is reduced, the operation cost is reduced, the planting quality is improved, ditches with different sizes can be dug, the adaptability is high, and the problem that soil is scattered around when the pits are dug is effectively avoided.

Description

technical field [0001] The invention relates to the technical field of digging methods for planting trees, in particular to a digging method for a portable variable-diameter surrounding digging machine.
