Soil-loosening device for agricultural planting

Abstract

The invention discloses a soil-loosening device for agricultural planting. The soil-loosening device comprises a positioning part and a plurality of rake teeth, wherein the positioning part comprisesa fixed member, a limit member and a connecting member; the connecting member is arranged at the center of the top part of the fixed member; two ends of the fixed member are fixedly connected with thelimit member; a plurality of adjusting bolts are arranged on the limit member; the exteriors of the plurality of the adjusting bolts are respectively provided with a through hole; each adjusting member arranged on a rake tooth penetrates through a through hole to connect to an adjusting bolt in a threaded manner; each adjusting member is composed of an adjusting nut and a connecting bearing; eachrake tooth is divided into a top adjusting part and a bottom soil-loosening part; each top adjusting part has a hollow structure; the interior of each top adjusting part is provided with a cavity; the bottom soil-loosening part has a solid structure; and the bottom part of each bottom soil-loosening part is of a pointed cone shape. According to the invention, through arrangement of the adjustingbolts and the adjusting members, the length of the part of each rake tooth away from a limit member can be adjusted, so the device provided by the invention has the effect of adjusting the ploughing depth of the rake teeth; thus, the device provided by the invention can adjust the loosening depth of according to growth habits of different crops, is applicable to mechanical use, and facilitates growth of the 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
