Hardened soil treatment and remediation system for greening

Abstract

The invention relates to the technical field of hardened soil treatment and remediation, and relates to a hardened soil treatment and remediation system for greening, in particular to a hardened soiltreatment and remediation vehicle for farmland planting. The system adopts a vehicle body design, and is convenient to move in a farmland; based on a transmission design, a soil turning device turns up hardened soil when the system advances, the turned-up soil is sucked into a soil inlet pipe and conveyed to the upper portion under the action of a spiral packing auger, then the turned-up soil is discharged into a main body barrel, and automatic feeding of the hardened soil is achieved; and the soil is crushed, plant ash is intermittently added into the crushed soil, and then the crushed soil is discharged back to the farmland through a soil discharge pipe, so that the online remediation of the hardened soil of the farmland is realized.

Description

technical field [0001] The invention relates to the technical field of compacted soil treatment and restoration, and relates to a compacted soil treatment and restoration system for greening, in particular to a compacted soil treatment and restoration vehicle for farmland planting. Background technique [0002] Farmland, also known as cultivated land, refers to the land that can be used to grow crops in geography, and is the basic resource and condition for human survival. [0003] Soil compaction is often encountered during farmland reclamation. [0004] Soil compaction refers to the phenomenon that the surface layer of the soil is poor in structure due to the lack of organic matter, and the structure is destroyed and the soil material is dispersed under the action of external factors such as irrigation or rainfall, and the soil surface is hardened by the cohesive force after drying. [0005] The reasons for soil compaction mainly include the following aspects: [0006] 1...

AI Technical Summary

Problems solved by technology

[0008] 3. Plastic waste pollution;

[0009] 4. Long-term single partial application of chemical fertilizers;

[0010] 5. Agricultural measures such as suppression and plowing lead to the destruction of the upper soil structure;

[0011] 6. Accumulation of harmful substances;

[0012] 7. Heavy rains cause soil erosion

[0013] Under the condition of soil compaction, the soil porosity is reduced, the permeability is poor, and the ground temperature is lowered, so that the activities of aerobic microorganisms in the soil are inhibited, and the water, air, and heat conditions cannot be well coordinated, and its fertilizer supply, fertilizer, and water retention capabilities are weak.

[0014] Soil compaction also delays the decomposition of organic matter, the physical and chemical properties of the soil gradually deteriorate, the soil fertility gradually declines, and the soil fertility decreases, so nature cannot well meet the needs of crop growth and development.

[0015] Under the condition of soil compaction, the respiration of the root cells of crops is weakened, and nutrients such as nitrogen exist in the ion state, and the absorption is mostly in the form of active transport, which needs to consume the energy produced by cell metabolism, and the respiration is weakened, so the energy supply is insufficient, affecting absorption

[0016] The restoration of compacted soil in the prior art is mostly to excavate the compacted soil in a large area and transport it to the soil treatment machine for unified treatment, and then transport the treated soil back to the farmland and spread it out again. Obviously, the area of ​​farmland is calculated in mu. This method requires a large transportation cost. Therefore, it is necessary to design a device that can directly repair compacted soil in the farmland.
