1、 The function of the depth limiting wheel
The depth limiting wheel of a corn planter is a device that adjusts the depth of seed sowing. It controls the depth of corn seeds by changing the depth position of the depth limiting wheel. By adjusting the position of the depth limiting wheel under different soil and humidity conditions, corn seeds can fall to the appropriate depth, thereby avoiding uneven sowing caused by uneven depth. At the same time, the depth limiting wheel can also avoid crushing and scratching of corn seeds when they land, effectively improving the survival rate and germination rate of seeds. Therefore, the depth limiting wheel is an indispensable component of corn seeders.
2、 Installation method of depth limiting wheel
The installation of depth limiting wheels should be determined based on the specific type of seeder and soil environment. Generally speaking, the depth limiting wheel should be spaced 10-15mm away from the sowing tray, so that it will not overturn the soil when it comes into contact with it. When installing, it is necessary to first correctly connect the depth limiting wheel to the fixing pin, and then fix the depth limiting wheel above the sowing plate with bolts. Use adjustment screws and compression springs to adjust the depth position of the depth limiting wheel.
3、 Maintenance and upkeep of limited depth wheels
To ensure the normal use of the depth limiting wheel, it is necessary to regularly inspect and clean the depth limiting wheel and its hole. When the depth limiting wheel is damaged or worn, it needs to be replaced in a timely manner. Because using damaged depth limiting wheels can affect the sowing depth and quality of seeds, as well as the yield and quality of crops.
In short, the depth limiting wheel of a corn planter plays a very important role in controlling the depth of corn seeds, avoiding uneven sowing caused by uneven depth, and effectively improving sowing efficiency and yield. In order to ensure the normal use of the depth limiting wheel, it is necessary to regularly inspect and clean it, and replace damaged depth limiting wheels in a timely manner.
