[0002] A corn planter is usually a tool specially designed for corn planting. When planting corn, a suitable planting depth can provide the seeds with suitable temperature, humidity and oxygen conditions, which is conducive to the rapid and uniform germination of the seeds. Proper depth control can reduce the difficulty or uneven germination of seeds due to too deep or too shallow planting, thereby improving the germination rate. In the prior art, there is a corn planter with an auxiliary control function for planting depth. Its technical solution includes a base plate, a soil turning block with adjustable height at the bottom of the base plate, a feeding hopper above the base plate, a filter screen in the feeding hopper, and a material dividing mechanism for intermittent sowing of corn seeds below the base plate.
