Description

Technical Field

[0001] The invention relates to the technical field of agricultural machinery sowing, and in particular to a novel agricultural machinery sowing pressing wheel. Background Art

[0002] The agricultural machinery sowing press wheel is a device used on the seeder, which is mainly used to adjust and control the compaction degree of the soil covering the seeds after sowing to ensure that the seeds can have good contact with the soil, thereby improving the emergence rate. This equipment is usually composed of a press wheel, an adjustment frame, a press wheel connecting rod and other components. By adjusting the position and pressure of the press wheel, precise control of soil compaction can be achieved;

[0003] When the pressing wheel travels in wet soil for a long time, wet soil is easy to adhere to the surface of the pressing wheel, and will accumulate more and more as the pressing wheel operates. When thick soil is accumulated on the surface of the pressing wheel, the soil will also accumulate in the frame of the pressing wheel. When the frame of the pressing wheel is clogged with soil, the pressing wheel will be stuck. The stuck pressing wheel will push the soil at the bottom to move as the seeder moves. At this time, the seeder has already completed sowing the seeds. The pressing wheel pushing the soil to move will easily turn the seeds out and affect the sowing effect. Summary of the invention

When the pressure of the pressing wheel 3 needs to be adjusted, the hexagonal nut 10 is twisted to move on the surface of the vertical rod 6. When moving, the hexagonal nut 10 pushes the inclined frame 5 to move through the connection between the spring 8 and the lifting ring 7. The inclined frame 5 pushes the mounting frame 1 to adjust the pressure of the pressing wheel 3. When the pressing wheel 3 is working, the scraping component 12 is started to work, and the scraping component 12 is used to clean the soil of the pressing wheel 3 to avoid more and more soil accumulation on the pressing wheel 3, thereby affecting the compaction effect of the pressing wheel 3 on the soil.
