Saline-alkali soil deep ploughing irrigation regulating treatment all-in-one machine

Abstract

The invention discloses a saline-alkali soil deep ploughing irrigation regulating treatment all-in-one machine which comprises a reeling type irrigation supply device and a deep ploughing irrigation machine tool vehicle; the reeling type irrigation supply device comprises an irrigation reel, an irrigation reel drive and a water supply PE pipe; the deep poughing irrigation machine tool vehicle comprises a vehicle body, lifting wheels, deep ploughing machine tools, a hydraulic control device and an irrigation water distribution structure; the top ends of the deep ploughing irrigation machine tools are connected to the vehicle body in a hinged mode, the bottom end of each deep ploughing irrigation machine tool is of a hook structure which bends forwards and is provided with a hollow cavity, an irrigation opening is formed in the rear portion of the bottom end of each hook structure, and the deep ploughing irrigation machine tools are connected with the vehicle body through machine tool lifting hydraulic cylinders; the water outlet end of the irrigation water distribution mechanism is communicated with the hollowing cavities of the hook structures of the deep ploughing irrigation machine tools. The saline-alkali soil deep ploughing irrigation regulating treatment all-in-one machine can achieve the phenomenon that soil secondary salinization is prevented on the premise that a water resource is saved, and the governance cost is lowered, efficient organic fertilizer application can be achieved, and the machine is especially suitable for initial improvement regulation of saline-alkali soil high in degree of alkalisation.

Description

technical field [0001] The invention relates to land improvement equipment, in particular to an integrated machine for deep plowing, irrigation, improvement and treatment suitable for improvement of soil with poor water conditions such as saline-alkali land, and belongs to the technical field of soil improvement equipment. Background technique [0002] Saline-alkali land is a type of salt accumulation, which means that the salt contained in the soil affects the normal growth of crops. According to the incomplete statistics of UNESCO and FAO, the area of ​​saline-alkali land in the world is 954.38 million hectares, of which my country is the largest 99.13 million hectares, most of the formation of alkaline soil and alkalized soil in my country is related to the accumulation of carbonate in the soil, so the degree of alkalization is generally high. , Compaction, slow rise in soil temperature, slow water release, low permeability coefficient and a series of deterioration of soil ...

AI Technical Summary

Problems solved by technology

[0004] In saline-alkali land areas, there are usually problems such as lack of fresh water resources, groundwater salinization, and high groundwater levels. This traditional flood irrigation method not only consumes a lot of irrigation water, consumes a lot of energy, and costs a lot of treatment, it is easy to cause waste of water resources. If it is not timely, it will lead to the rise of groundwater, causing secondary salinization of the soil; at the same time, due to the compactness of the saline-alkali ground floor and the slow release of water, the efficiency of salt dissolution is low, time-consuming, and the effect is not obvious; in addition, for
