Perforating device for planting seedlings

Abstract

The invention relates to the technical field of seedling planting and discloses a perforating device for planting seedlings. The perforating device comprises a protective shell, wherein four sliding sleeves are fixedly arranged at the positions, close to corners, of an inner cavity of the protective shell; a support rod is movably sleeved with each sliding sleeve; a power device is fixedly arranged in the inner cavity of the protective shell; and one end of the power device is movably sleeved with a drill rod. The drill rod is movably sleeved with a driven pulley, so that the drill rod can descend through self-gravity and can carry out drilling through the self-gravity as power in the drilling process; and due to gravity inconvenience, the drill rod voluntarily accelerates the driving speed in soft soil and voluntarily reduces the driving speed in hard soil, and a drill bit can voluntarily stop drilling when encountering a stone or other hard materials, thereby avoiding the problem that the drilling speed of the drill bit in original equipment cannot be voluntarily adjusted according to the soil condition of the soil into which the drill bit is positioned.

Description

technical field [0001] The invention relates to the technical field of seedling planting, in particular to a punching device for seedling planting. Background technique [0002] Seedlings are saplings with roots and stems. They are tree seedlings cultivated in nurseries. They can be transplanted and planted. They are used in urban greening, residential area greening, road greening, river embankment greening and other greening functions. , in the process of planting seedlings, it is necessary to dig holes for planting. Here, a punching device for seedling planting is needed to replace manual hollowing, which can greatly improve the efficiency of punching. [0003] Patent No. CN201811167227.X discloses a quick drilling device for seedling planting in the field. The drill is driven by a motor to drill holes, and at the same time, the direction of drilling is stabilized by holding the handle. This method lacks a fixing device, and the drilling process starts The radial moment g...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies in the use of the existing seedling planting punching machine proposed in the background technology, the present invention provides a seedling planting punching device, which has the ability to drill holes by relying on its own gravity as the main driving force. The advantage of self-adjusting drilling speed in the soil structure solves the problem of inconsistency between the drilling speed of the drill bit and the descending speed of the support plate during the drilling process of the original equipment
