Convenient ground earth drill with rotation speed regulating function

Abstract

The invention relates to a convenient ground earth drill with a rotation speed regulating function. The convenient ground earth drill comprises a main body and a drill bit, and further comprises a speed regulating mechanism and a dismounting mechanism, wherein the dismounting mechanism comprises a drive shaft, a first connecting disc, a second connecting disc, a first sleeve, a second spring, twofirst bearings and at least two connecting assemblies; the speed regulating mechanism comprises a transmission block, a friction disc, a motor and two movable assemblies; each connecting assembly comprises a through hole, a lead screw, a second bearing and a fourth sleeve; and each moving assembly comprises a third sleeve, a gas cylinder, a first slide rod and two resisting units; each resisting unit comprises a second slide rod, a second sleeve and a first spring. In the convenient ground earth drill with the rotation speed regulating function disclosed by the invention, the rotation speed ofthe drill bit can be regulated through the regulating mechanism, so that practicability of the earth drill is improved; and the dismounting mechanism improves drill bit replacement convenience, and improves convenience of earth drill use.

Description

technical field [0001] The invention relates to the field of forestry machinery, in particular to a convenient ground drill with the function of adjusting the speed. Background technique [0002] Ground drills are widely used in planting and digging pits for seedling landscaping projects on sloping land, sandy land, and hard land, digging out the periphery of large trees; Wait. Pit diameter: 200-600mm. The ground drilling operation is no less than 80 holes per hour. Calculated by working 8 hours a day, 640 holes can be dug, which is more than 30 times that of manual work. Cultivation, weeding with a width of more than 50 cm and an operation of no less than 800 square meters per hour, truly realize the fully automatic operation process, and the ground drill liberates people from heavy manual labor. Powerful, beautiful appearance, comfortable operation, low labor intensity, suitable for all terrains, high efficiency, easy to carry and field operations. [0003] The earth d...

AI Technical Summary

Problems solved by technology

[0003] The earth drill of the prior art does not have the function of speed regulation, so that the drill bit can only work at one speed, and cannot be adjusted according to the geology and the size of the pit, which reduces the practicability of the earth drill. Not only that, the earth drill of the prior art When in use, the drill bit wears out quickly, and the disassembly of the drill bit is generally time-consuming and laborious, which reduces the convenience of using the ground drill
