Description

Technical Field

[0001] The utility model relates to the technical field of soil restoration, in particular to a pulverizing and mixing device for saline-alkali land soil restoration. Background Art

[0002] Saline-alkali land refers to the salt content in the soil that affects the normal growth of crops. In the process of restoration, soil restoration agents must be used to effectively improve saline-alkali land. Generally speaking, soil restoration agents need to be in full contact with or even mixed with saline-alkali soil to be effective.

[0003] However, when using soil remediation agents in existing saline-alkali land, the soil remediation agents are often sprinkled on the surface of the saline-alkali land. This method of sprinkling on the surface is relatively simple to construct and is suitable for large-scale mechanized operations. However, there is a disadvantage that the soil remediation agent is difficult to fully mix with the saline-alkali land, and it may be necessary to improve the saline-alkali land by sprinkling water or flushing with rainwater. However, rainwater is generally irregular, and the ingredients in the soil remediation agent are easy to volatilize, resulting in less effective ingredients, which ultimately leads to poor soil remediation effects. For this reason, we propose a crushing and mixing device for saline-alkali land soil remediation to achieve full mixing of the soil remediation agent and the saline-alkali land soil, to maximize the efficacy of the soil remediation agent and achieve the purpose of remediation and improvement. Utility Model Content
