Integrated machine for in-situ hole digging, material mixing and backfilling and working method thereof

Abstract

The invention relates to an integrated machine for in-situ hole digging, material mixing and backfilling and a working method of the integrated machine for the in-situ hole digging, material mixing and backfilling. The integrated machine comprises a power system, a drill bit lifting device, a walking device and an operation device; the power system comprises an engine and a reducer; the drill bit lifting device comprises lifting hand wheel, a lifting reducer, a linear guide rail, a lifting frame, a chain wheel and a chain; the walking device comprises a supporting rear wheel and a supporting front wheel; the operation device comprises a drill bit, a sleeve rack, an upper sleeve, a lower sleeve, a discharge port baffle plate and a discharge pipeline; the invention puts forward an integrated design of in-situ hole digging, material mixing and backfilling for fruit tree planting to realize mechanized fruit tree planting process, the integrated machine for the in-situ hole digging, material mixing and backfilling is reasonable in structural design, low in cost, convenient to operate and use, high in efficiency of hole digging, material mixing and backfilling, and low in labor intensity. A hole digging and material mixing composite structure of the single-blade double-diameter drill bit and a lifting material mixing cavity is innovated, and performs hole digging and material mixing simultaneously, and further is high in efficiency and mixing uniformity of fertilizer, microorganisms and soil.

Description

technical field [0001] The invention relates to a tree planting machine, in particular to an in-situ digging, mixing and backfilling machine and a working method thereof. [0002] technical background [0003] my country's forest and fruit industry is developing rapidly, and has become a local pillar industry in Shandong, Shaanxi and other provinces. In recent years, fruit tree varieties and cultivation systems have been updated and improved. However, the problems of heavy cropping and stubble replacement in old orchards, nurseries and newly-built orchards, and soil-borne diseases faced by newly planted fruit trees have become more and more prominent, and the survival rate of newly planted saplings is low. The disease is serious, the yield quality declines, and the life span is short. This phenomenon is very common and has caused huge economic losses. The reason is that the soil is planted year after year, toxins accumulate, trace elements are exhausted, organic matter conte...

Problems solved by technology

[0004] However, the tree planting machinery in our country is mainly the traditional digging machine, which only has the function of digging pits, with a single function and a low degree of mechanization. It does not have the functions of mixing and backfilling, and is inefficient. It cannot meet the needs of modern agronomy, and often manifests as uneven mixing. , unable to maximize the effectiveness of bacterial fertilizers, etc.
