Problems solved by technology

[0004] The technical problem to be solved in the present invention is: during no-tillage sowing, there will be straw and weeds on the ground after the previous crop harvest, and during no-tillage sowing and fertilization, the ditch opener will hang grass and congest during the forward process, thereby affecting the quality of fertilization; In addition, since the ditch openers used for no-tillage sowing have high moisture content, heavy soil, and poor fluidity after ditching and fertilization, the covering soil is not reliable after furrowing and fertilization (especially the soil fluidity on both sides of the ditch is poor, Soil-covering and pressing wheels cannot reliably push the soil on both sides into the ditch), causing the seed ditch to fail to close, the seeds are exposed and cannot be covered by the soil, resulting in a decrease in emergence rate and affecting the quality of sowing

Embodiment 1

[0029] see Figure 1-Figure 7 , a stubble-breaking, ditching and fertilizing device for a no-tillage planter, comprising a ditch opener 3, characterized in that: it also includes a stubble-breaking assembly 1, a spring seat assembly 2, a connecting arm 5, and a suspension arm 6. The stubble assembly 1 is arranged directly in front of the ditch opener 3; the stubble breaking assembly 1 includes a stubble breaking disc part 101, and the disc part 101 has a sharp blade, which can cut the land when it rotates, and the ground surface Straw and weeds are cut off; the ditch opener 3 is used to ditch along the kerf; the central shaft of the stubble breaking assembly 1 is hinged to the connecting arm 5, and the connecting arm 5 is hinged to the main girder of the ditch opener; The front and rear ends of the spring seat assembly 2 are respectively hinged with the suspension arm 6 and the ditch opener 3, and the suspension arm 6 is hinged with the central shaft of the stubble breaking as...

Embodiment 2

[0036] see Figure 8-9 , on the basis of Embodiment 1, the device for breaking stubble, ditching and fertilizing the no-tillage seeder also includes a ditch edge loosening part 7, and the ditch edge loosening part 7 includes a pair of top-to-bottom inwardly inclined A ditch edge loosening disc part 701 that is symmetrical on both sides with the stubble breaking disc part 101 as the center, and the ditch edge loosening disc part 701 is corresponding to the position of the ditch soil, and the ditch soil is cut when rotating; The ditch edge loosening parts 7 are fixedly arranged directly behind the ditch opener 3 .

Abstract

The invention relates to a stubble-breaking, ditching and fertilizing device for a no-tillage planter. The stubble-breaking, ditching and fertilizing device comprises a ditching device and further comprises a stubble breaking assembly, a spring base assembly, a connecting arm and a hanging arm, and the stubble breaking assembly is arranged ahead of the ditching device. The stubble breaking assembly comprises a stubble breaking disc part, and the disc part is provided with a sharp blade; when the disc part rotates, land can be lanced, and straw and weed on the ground surface can be cut off. The ditching device is used for carrying out ditching along kerf; a center rotating shaft of the stubble breaking assembly is hinged to the connecting arm, and the connecting arm is hinged to a main beam of the ditching device; the front end and the back end of the spring base assembly are hinged to the hanging arm and the ditching device respectively, and the hanging arm is hinged to the center rotating shaft of the stubble breaking assembly. Tensile force is applied to the hanging arm through a tension spring inside the spring base assembly; when the stubble breaking disc part is blocked by a hard barrier, the stubble breaking assembly moves upwards and bypasses the main beam of the ditching device to rotate by a certain angle.

Description

technical field [0001] The invention relates to a stubble breaking, furrowing and fertilizing device for a no-tillage seeder, belonging to the technical field of the no-tillage seeder. Background technique [0002] No-till sowing, which does not damage the soil structure, is conducive to soil protection, and can save investment in machine tillage. It is a better planting method. [0003] However, after the previous crop harvest, there will be straw and weeds on the ground. During no-tillage sowing and fertilization, the ditch openers will hang grass and congest during the forward process, which will affect the quality of fertilization; in addition, because the ditch openers used in no-tillage After furrowing and fertilization, the soil moisture content in the south is high, the soil is heavy, and the fluidity is poor. After furrowing and fertilization, the covering soil is unreliable (especially the soil fluidity on both sides of the ditch is poor, and the covering soil pres...
