Saline-alkali soil repairing and improving device capable of carrying out multi-level mixed digging

Abstract

The invention discloses a saline-alkali soil repairing and improving device capable of carrying out multi-level mixed digging. The saline-alkali soil repairing and improving device capable of carrying out the multi-level mixed digging comprises an improving and repairing vehicle, an improvement agent storage tank, an air pump tank, a material guiding pipe, an air pipe, a telescopic hydraulic cylinder, an installation frame, a telescopic cabin and a spring, wherein the improvement agent storage tank is arranged on the top of the improving and repairing vehicle; the improving and repairing vehicle on one side where the improvement agent storage tank is positioned is provided with the air pump tank; the front side of a supporting plate is connected with a ditching roller through the installation frame; the right side of the ditching roller is provided with a discharging pipe; one side of the right side of the discharging pipe is provided with a first smashing roller and a second smashing roller; and meanwhile, the right side of the second smashing roller is provided with an installation cover. By use of the saline-alkali soil repairing and improving device capable of carrying out the multi-level mixed digging, the structure of an existing saline-alkali soil repairing device is improved, when soil is dug, especially by aiming at land of which the soil is wet, the problems that splashing soil blocks are attached to a material outlet to cause blockage can be solved, and the integral surface of the soil can be leveled.

Description

technical field [0001] The invention relates to the technical field of restoration and improvement of saline-alkali land, in particular to a device for restoration and improvement of saline-alkali land with multi-stage mixed excavation. Background technique [0002] In Northwest China, due to harsh climate conditions and lack of fresh water resources, a large amount of land in this area has been salinized, resulting in the inability of plants to grow. In order to solve the problem of plant growth, people began to repair and improve the saline-alkali land by adding restoration agents. For example, the comparative document application number: CN201810877606.1, publication date: 20181211 is a kind of saline-alkali land ecological restoration device, the saline-alkali land restoration device of the present invention can greatly improve the effect and restoration efficiency of saline-alkali land restoration. As for the restoration agent storage box, the material can be automatica...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to provide a kind of saline-alkali soil restoration and improvement device of multi-stage mixed excavation, to solve the existing saline-alkali land restoration and improvement device on the market proposed by the above-mentioned background technology. When the cutter wheel excavates and loosens the soil, some soil clods will be splashed. When the soil is relatively wet, the flying soil clods will easily adhere to the discharge port, and the problem of blockage of the discharge port will easily occur. , after the excavation of the land, due to the excavation of the rotary tiller wheel, it is easy to cause the unevenness of the soil surface, which affects the overall flatness of the land after restoration, and is inconvenient for subsequent sowing and planting operations on the repaired land
