Problems solved by technology

[0002] At present, the existing seeders mainly have the following defects: 1. The positioning point of the sowing depth of the existing seeders is on the ground, and the land needs to meet the mechanical sowing conditions, rather than the machinery to adapt to different lands

During use, the contact point between the driving wheel and the ground keeps rising and falling, and the sown seeds will be deep and shallow, resulting in uneven emergence, long emergence time and low emergence rate, resulting in reduced crop yields

2. The two driving wheels of the existing seeder are positioned on the ground, load-bearing and drive the seeder to work, and sow seeds in the same field. The driving wheel is raised, and the sowing basket feet, fertilization basket feet, and ridge plows installed before and after the sowing wheel are raised accordingly, and the sown seeds are shallow, or even completely exposed on the ridge surface; when the driving wheel moves When the soil is soft, the soil is fine, the soil is loose, the moisture is waterlogged, or the ground is concave, the driving wheel will sink immediately, and the basket legs, plows and other parts will also be tied down, and the seeds sown will be deep, even as deep as 100mm. At the same time, the front of the cover plate is full of mud, so the tractor can't pull it, the driving wheel slips, the seeds are not evenly sown, the crop seedlings are uneven, the seedlings are weak, and the yield is reduced.

Because the two driving wheels are installed at both ends of the same shaft, they travel across the ridges and have synchronization, and can only run straight or approximately straight. When planting on a curved hillside, the tractor turns and the planter cannot turn. Forced pulling and dragging will cause lateral movement when moving forward, so the width of the furrows is inconsistent, wasting land

The planter cannot work in the sprinkler irrigation field, the ground of the sprinkler irrigation field cannot be level, the relative humidity of the convex place is low, the sown seeds will be shallow, and the relative humidity of the concave place is high, and the sowing will be deep

3. The ridge supported by the existing seeder is a low trapezoidal ridge with a narrow surface and a small lighting area

4. Existing planters use soil-covering boards to scrape the ridge surface, which has high resistance, and also causes uneven width and unevenness of the ridge surface, which affects the quality of the covering film. At the same time, the soil covering the seeds is loose, which is not conducive to water absorption, germination, rooting, and growth of the seeds.

5. The existing seeder adopts a row of fertilization in the middle of the ridge. The fertilization is shallow and concentrated, which makes it difficult for crops to absorb and rots easily.

6. The laminating device of the existing seeder is not coordinated with the film releasing rod and the laminating roller, the film is not fully developed, it is easy to wrinkle and tear the edge, the tension is not tight, the laying is not smooth, the pressure is not tight, and the ditch is still glued. When the wind is strong, the film is placed The mulching film on the film rod will automatically unfold, and it cannot be covered when it flutters with the wind. Every time a new ridge is covered, the film needs to be manually stretched and pressed to start work, which is time-consuming and laborious.

There are gaps between the hitch collar, the pin, and the hole of the traction plate. The gap between the hitch and the traction device is adjusted by rotating the bolt. This adjustment method is difficult to achieve the desired effect. Hold the handrail of the tractor, raise the planter to turn, and the planter does not swing left and right, then when the planter is put down to work, there will be no reasonable movable gap between the traction device and the hitch device, and the two cannot work together. If there is a reasonable working gap between the hitch devices, when the seeder is raised, the seeder will swing from side to side, which is easy to hurt the operator's legs, which is extremely unsafe. Correcting the position of the planter to keep it in line with the tractor is time-consuming and labor-intensive
