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 ...

Embodiment

[0021] Example: such as Figure 1-3 As shown, an agricultural planting and loosening device includes a positioning part 1 and several rake teeth 2. The positioning part 1 includes a fixing part 3, a limiting part 4 and a connecting part 5. The connecting part 5 is installed at the top center of the fixing part 3. The two ends of the fixing part 3 are fixedly connected with the limit part 4, and a number of adjusting bolts 6 are installed on the limit part 4, and through holes 7 are arranged on the outside of the several adjusting bolts 6, and the adjusting part 8 installed on the rake tooth 2 passes through the through hole. The hole 7 is threadedly connected with the adjusting bolt 6. The adjusting member 8 is composed of an adjusting nut 9 and a connecting bearing 10. The diameter of the connecting bearing 10 is larger than that of the adjusting nut 9, and the bottom of the connecting bearing 10 is integrally formed with the rake teeth 2. The rake teeth 2 are divided into an...
