[0002] Corn is one of the main food crops in my country and is of great significance in maintaining food security. At present, many efforts have been made across the country to improve the utilization rate of cultivated land. Therefore, it is often planted in some orchards, tea gardens, open spaces in front of and behind houses, greenhouses, remote and small plots of cultivated land to improve soil utilization. However, small plots of cultivated land are often inaccessible to machinery, so a hand-push corn planter is needed for planting. The existing hand-push corn planter has the following shortcomings:

[0003] 1. The seed drill drives the main shaft through a chain to drive the seeder for sowing. When moving, the raised soil may get stuck in the chain, causing the seed drill to get stuck and need to be stopped for processing, which brings inconvenience to sowing and affects sowing efficiency.

[0004] 2. The existing seeding machine has a relatively sophisticated mechanical structure, which makes it more complicated to replace the seeding machine with different spacing, which is difficult for experienced farmers to master;

[0005] 2. After the corn seeds are sown in the seedbed, they need to be covered with soil again, which requires additional covering operations, thus affecting the sowing efficiency. Utility Model Content
