Smashing and planting integrated system for straws in soil

Abstract

The invention provides a smashing and planting integrated system for straws in sow, and relates to the field of seeding equipment. The smashing and planting integrated system comprises a smashing device, a seeding device and a guiding mechanism, the smashing device comprises a rack, a picking mechanism and a rotary tillage mechanism, the picking mechanism comprises a picking licker-in, a collecting cylinder and a fan, the collecting cylinder is of a local cylinder structure with an opening in the side wall, one end of the collecting cylinder communicates with the guiding mechanism through the fan, a groove is formed in the opening position of the collecting cylinder in the circumferential direction, the picking licker-in is rotationally installed on the rack, picking needles distributed in the radial direction are arranged on the outer circumferential face of the picking licker-in, and the picking needles are used for penetrating into the soil to pick up the straws under the rotation of the picking licker-in and feeding the straw into the collecting cylinder in cooperation with the groove; the guiding mechanism is used for conveying the straws in the collecting cylinder to a sown area after the seeding device works; a rotating licker-in is arranged to be matched with the collecting barrel to pick up and clean the straw in the shallow soil body of a straw returning area, straw residues in the shallow soil body are reduced, and the problem that straw fragments affect seed germination and growth is solved.

Description

technical field [0001] The present disclosure relates to the field of sowing equipment, in particular to an integrated system for crushing and planting straw in soil. Background technique [0002] For middle and high latitude regions, fields are often cultivated by crop rotation. Wheat needs to be sown in time after the previous crops of corn, rice, and cotton are harvested, and corn and other crops need to be sown in time after wheat is harvested. With the advancement of mechanized harvesting , there are often straws left in the field after receiving the goods, especially for the harvested corn straws. The roots, stems and leaves are crushed intensively. [0003] Although the straw is effectively reduced in volume after being returned to the field through rotary tillage, so that the whole can be retained in the soil as a nutrient; It is difficult to meet the demand for fine sowing of wheat in this state; on the one hand, the straw is not completely crushed, and the remain...

AI Technical Summary

Problems solved by technology

[0003] Although the straw is effectively reduced in size after being returned to the field by rotary tillage, so that the whole can be retained in the soil as a nutrient; It is difficult to meet the demand for fine sowing of wheat in this state; on the one hand, the straw is not completely crushed, and the remaining straw causes the planter to ditch and hang grass; In the seed area, it is easy to cause the wheat root system to be unable to effectively land on the soil, resulting in root instability and affecting the planting effect in the fine sowing area; Seed growth leads to disease
