Automatic rope release device for direct seeding machine

Abstract

The invention discloses an automatic rope releasing device for a direct seed rope sowing machine, and belongs to the technical field of farm-oriented sowing machines. The automatic rope releasing device comprises a rope guiding pipe, a seed rope disc, a furrow compacting wheel and a rope compacting device, wherein the rope fixing pipe is fixed laterally below the seed rope disc on a rack and above the furrow compacting wheel, on end of a rope compacting device is connected to the rack, the other end of the rope compacting device is compacted on the furrow compacting wheel, the seed rope end of the seed rope disc penetrates through the rope guiding pipe, and passes through two rope compacting wheels of the rope compacting device and the furrow compacting wheel, the two rope compacting wheels rotate together with the furrow compacting wheel under the action of friction force, a seed rope is clamped and compacted by the rope compacting wheels and the furrow compacting wheel, and the seed rope is compacted in a seed furrow with the rolling and advancing of the furrow compacting wheel. According to the automatic rope releasing device, through common action of the rope guiding pipe, the rope compacting wheels and the furrow compacting wheel, the automatic rope releasing is realized, the problem of manually releasing and compacting the rope in the field is solved, the automation degree is improved; by regulating relative positions of the rope compacting wheels, the seed rope and the furrow compacting wheel, the seed rope is straightened, and the seeding quality is improved. According to the automatic rope releasing device, by arranging a furrowing wheel with a compacting groove, a furrowing form is changed, and the consistency of sowing depths is favorably ensured.

Description

Technical field [0001] The invention belongs to the technical field of agricultural planters, and particularly relates to an automatic rope-laying device for a seed rope direct seeding machine. Background technique [0002] At present, farmland seeding can be divided into manual seeding and mechanical seeding. The advantage of traditional manual seeding is simple operation. The disadvantages are: a lot of labor and a large amount of seeds, it is difficult to control the row spacing and plant spacing, and there are often problems of excessive dense planting or uneven density. Although mechanical seeding has improved the seeding rate and the uniformity of seeding, it will also be affected by factors such as soil conditions. It also has the problems of large seeding quantity and unequal distance, and there are also problems such as uneven fertilization with seed and uneven application of medicine. [0003] As scientific research continues to innovate, seed rope live broadcast technol...

Problems solved by technology

The disadvantages are: a lot of labor, a large amount of seeds, it is difficult to control the row spacing and plant spacing, and there are often problems of excessive dense planting or uneven density

However, it is still in the manual stage, which is not suitable for large-scale operations, and the quality of seedling emergence cannot be guaranteed by making ropes and sowing by hand.
