Background

In order to ensure the follow-up of the sowing tray and the depth-stop wheel, the gap between the sowing tray and the depth-stop wheel of the conventional no-tillage sowing machine is very narrow, as shown in fig. 5.

When the wet sticky land is operated, the mud is easily clamped between the sowing disc and the depth limiting wheel at a small distance, so that the equipment cannot be operated. The operation is also the same in soft soil texture blocks and straw blocks, and as the soil in front of the depth-limiting wheel is soft, the distance between the depth-limiting wheel and the sowing disc is very short, the situation of dragging the front of the wheel is caused, and after the dragging is serious, the sowing disc and the depth-limiting wheel are blocked and do not rotate, so that the equipment can not operate.

Because the problem of mud and soil clamping often occurs between the seeding disc and the depth limiting wheel of the existing no-tillage seeding machine, the connection structure between the seeding disc and the depth limiting wheel is very required to be improved.
