Polluted soil cultivation device for use in backhoe excavator

Abstract

The present invention relates to a polluted soil cultivation device, capable of cultivating a large amount of the polluted land within a short period of time with the aid of a front end cutter that consists of a cutting blade attached to a hot steam injection pipe. The polluted soil cultivation device for use in backhoe excavator of the present invention comprises: a connection link connected and attached to an arm of the backhoe excavator; a connection bar, which has an elongated flat plate form perpendicular to the direction of motion of the arm and one side of which is attached and fixed to the connection link; frames arranged evenly on both sides of the connection bar; and a pair of rotating parts having a plurality of blades, the rotating parts being supported in a rotating manner on the top and bottom portions of the frame.; With the pair of rotating parts of the present invention, one can freely cultivate an area of land that is polluted even at a depth of at least 1m, smoothly turn the polluted soil over and crush it, and easily turn the at least 1m-deep polluted soil over to the top to blend and crush with the soil on the top.

Description

technical field [0001] The present invention relates to a cultivating device for contaminated soil used in a backhoe, and more specifically, to a backhoe with a front end cut portion composed of a cut piece to which a high-temperature steam injection pipe is attached so that it can be used in a short period of time Contaminated soil tillage device for a backhoe that tills larger volumes of contaminated soil. Background technique [0002] In general, accidents of oil leakage or loss occur when underground oil storage tanks or their pipelines in gas stations, military or industrial areas are aged or damaged. In this case, the oil will inevitably flow into the soil, and the soil will be polluted, and animals and plants cannot grow normally in such polluted soil. So, in order to normalize the polluted soil, farming work is done. And the same goes for landfilling food waste. [0003] This kind of farming work is roughly the following aerobic biodegradation project. After the s...

AI Technical Summary

Problems solved by technology

First, a large space is required

Second, it takes a lot of time to completely remove the hard-to-decompose substances because an appropriate state for decomposing the polluted substances is not formed

Third, the activity of microorganisms is reduced due to the influence of winter temperature

Fourth, earth-diversion works consume a lot of energy

First, although a large amount of polluted soil can be turned over, the cost of mechanical power for farming is high, and the workload of machinery and auxiliary manpower is higher than that of the farming process using the above-mentioned tractors.

Second, human labor is required to periodically spread microorganisms and nutrients (nitrogen, phosphorus) during farming operations

Third, the moisture content in the polluted soil increases due to periodic tillage, and the sand falls in a box shape with a bucket specification during subsequent tillage, so it is impossible to obtain the crushing effect of subdividing according to the soil particles by crushing as in the present invention.

Fourth, the blind area that produces purification

That is, due to the high open-air accumulation height of the polluted soil, the polluted soil in the deep plowing part cannot be broken down smoothly, and the amount of microorganisms and oxygen supplied to the polluted substance (oil) between the particles of the above-mentioned sand soil decreases. , followed by a decrease in purification efficiency

Fifth, it is difficult to mix the microorganisms and nutrient solution in the polluted soil

First, when the tillage equipment of the rotary crushing method breaks the hard solid matter of the polluted soil, foreign matter such as stones and plastics are sandwiched between the screws, the effect of turning the soil is significantly reduced, and frequent failures occur due to high mechanical loads. and requires frequent checks

Second, in particular, although the degree of crushing has been improved compared to conventional tractors and backhoes, it is difficult to apply it to a construction site where a large amount of contaminated soil is turned over or crushed by excavation crushing.

[0009] The purpose of the above-mentioned tillage device for cultivating polluted soil is to cultivate the depth of 0-50cm underground, so in order to perform more effective and economical tillage of polluted soil, it is necessary to cultivate within 50-100cm, but to Tillage devices for this till now do not exist
