A soil loosening device for agricultural planting

Abstract

The invention discloses an agricultural planting loose soil device, which comprises a positioning part and a plurality of rake teeth. The positioning part comprises a fixing part, a limiting part and a connecting part. The connecting part is installed at the top center of the fixing part, and the two ends of the fixing part are fixedly connected Limiting parts, a number of adjusting bolts are installed on the limiting parts, and through holes are arranged on the outside of the several adjusting bolts. 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 connected by adjusting nuts and The rake teeth are composed of a top adjustment part and a bottom loosening part. The top adjustment part is a hollow structure with a cavity inside. The bottom loosening part is a solid structure and the bottom is a pointed cone. ; The present invention can adjust the length of the rake teeth to expose the limit parts through the provided adjusting bolts and adjustment parts, so that the device has the function of adjusting the rake teeth plowing depth, so that the depth of loose soil can be adjusted according to the growth habits of different crops, It is suitable for mechanical use and is conducive to the growth of crops.

Description

technical field [0001] The invention relates to the technical field of farming machinery, in particular to an agricultural planting soil loosening device. Background technique [0002] In agricultural production, cultivating the soil is an essential step, but different crops have different requirements for the depth of soil cultivating. Root crops require a deep soil layer, generally 75cm, and the critical value is 50cm-75cm; cereal crops , 50cm can be considered the best, 25cm-50cm is critical. Among crops, the root systems of cotton, sorghum, corn, etc. are relatively deep, requiring farmers to loosen the soil deeply when cultivating the soil; while the root systems of rice, millet, sweet potatoes, peanuts, etc. are relatively shallow, so there is no need to cultivate deeply soil, but the existing loosening device does not have the function of adjusting the plowing depth of the rake teeth, and mainly relies on the farmers' own experience; however, with the development of ...

Problems solved by technology

Among crops, the root systems of cotton, sorghum, corn, etc. are deep, requiring farmers to loosen the soil deeply; while the root systems of rice, millet, sweet potatoes, peanuts, etc. are shallow, so there is no need to plow deep soil, but the existing loosening device does not have the function of adjusting the plowing depth of the rake teeth, and mainly depends on the farmers' own experience; however, with the development of agricultural mechanization, more and more farm work has been completely handed over to the machine. If there is no loosening device for adjusting the tillage depth, it is impossible to adjust the depth of loosening soil according to the growth habits of different crops, which is not conducive to the growth of crops
