Description

Technical Field

[0001] The invention belongs to the technical field of soil loosening devices, and in particular relates to an agricultural planting soil loosening device. Background Art

[0002] In agricultural planting, loosening the soil is an important farming operation, and its main purpose is to improve the physical properties and ecological environment of the soil, thereby creating more favorable conditions for the growth of crops. Loosening the soil can break the compaction of the soil, increase the pores between soil particles, and increase the aeration of the soil. This is crucial for the respiration of crop roots, because the roots need oxygen for aerobic respiration, thereby releasing energy and supporting the growth and absorption function of the roots. In compacted soil, harmful gases such as carbon dioxide and methane are easily accumulated, which will inhibit the growth of the roots and even cause root rot. Loosening the soil can promote the discharge of these harmful gases and reduce the toxic effects on the root system. The soil structure after loosening the soil is looser, and the roots can more easily expand to the depth and the surrounding, thereby increasing the absorption area of ​​the roots and improving the absorption capacity of water and nutrients. The compact soil has a large mechanical resistance to the growth of the root system. Loosening the soil can reduce this resistance, allowing the roots to grow more freely and reduce the bending and deformation of the roots. Loosening the soil can make the soil layer on the surface of the soil loose, which is conducive to the absorption and conduction of solar radiation, thereby increasing the soil temperature and promoting seed germination and seedling growth. The rough soil surface formed after loosening the soil can reduce the evaporation of soil moisture and maintain soil moisture. This role is particularly important in arid areas or dry seasons. Loosening the soil can improve the air permeability and humidity conditions of the soil, provide a better living environment for soil microorganisms, and promote their activities. Soil microorganisms are more active in a suitable environment, which can accelerate the decomposition of organic matter in the soil and release more nutrients for crops to absorb and utilize.

[0003] According to the patent with announcement number CN 108990431 A, an agricultural planting loosening device is proposed, which includes a positioning part and a plurality of rake teeth. The positioning part includes a fixing part, a limiting part and a connecting part. The connecting part is installed at the top center of the fixing part. The two ends of the fixing part are fixedly connected to the limiting part. The limiting part is installed with a plurality of adjusting bolts. The outer parts of the plurality of adjusting bolts are all provided with through holes. The adjusting parts installed on the rake teeth pass through the through holes and are threadedly connected with the adjusting bolts. The adjusting parts are composed of an adjusting nut and a connecting bearing. The rake teeth are divided into a top adjusting part and a bottom loosening part. The top adjusting part is a hollow structure with a cavity inside. The bottom loosening part is a solid structure with a pointed cone at the bottom. The present invention can adjust the length of the rake teeth exposed from the limiting part by the adjusting bolts and the adjusting parts, so that the device has the function of adjusting the tillage depth of the rake teeth, so that the depth of the loosening can be adjusted according to the growth habits of different crops. The device is suitable for mechanical use and is conducive to the growth of crops.
