A kind of digging device for tree planting with no stagnant water and variable diameter in wetland

Abstract

The invention discloses a wet soil-free and variable-diameter tree-planting digging device in the field of planting technology, comprising: a bearing assembly; a cylinder rod is embedded on the component struts of the rectangular support frame; a water diversion digging assembly , the bottom of the installation pipe is fixedly connected with a precession drill bit; the linkage assembly includes a drive motor arranged on the base; the pneumatic variable diameter assembly is arranged in the inner cavity of the installation pipe; The initial foundation pit is pre-drilled on the wet land, so that the blade plate gradually moves outward, and the moving direction is diagonally upward, extending outward from the original foundation pit to expand the area of ​​the foundation pit, and the inner bottom surface of the newly formed foundation pit is inclined. The structure is convenient for the water that leaks again to quickly flow into the deep pit dug by the rotary drill bit, which can quickly discharge the leaked water, and avoid the subsequent trouble of the staff for the problem of water accumulation in the foundation pit, which cannot be effectively solved. problem, and improve the planting efficiency of the staff.

Description

technical field [0001] The invention relates to the technical field of planting, in particular to a digging device for planting trees with no ponding water and variable diameter in wetlands. Background technique [0002] Planting is plant cultivation, including the cultivation of various crops, forest trees, fruit trees, flowers and plants, medicinal and ornamental plants, including food crops, cash crops, vegetable crops, green manure crops, fodder crops, and pastures. The aim is to maximize the use of resources, reduce waste and reduce costs. Using non-polluting land, water area and natural environment, or using ecological technology measures to improve planting water quality and ecological environment, planting according to the specific planting mode of Dayi planting, without the use of chemical fertilizers, pesticides and other harmful substances, etc., the goal is to produce Pollution-free green food and organic food. Component probiotic stock solution for ecological ...

AI Technical Summary

Problems solved by technology

[0003] During the planting process, sometimes it is necessary to plant saplings in wet land areas, but it is easy to encounter some problems when digging holes before planting. For example, after digging a certain depth of foundation pit, due to the moisture in the wet land If the content is high, the water will leak into the excavated foundation pit, causing the problem of water accumulation in the foundation pit. If drainage is not carried out, it will easily cause the root of the sapling to rot after planting. If drainage is carried out, due to the accumulation of water in the foundation pit The diameter is generally suitable for the saplings, and it is difficult to effectively drain the accumulated water, which will cause trouble to the staff. Therefore, we propose a tree planting digging device with no water in wet land and a variable diameter type
