Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery, in particular to a corn dense planting sowing and metering device. Background Art

[0002] Corn dense planting seeder is a kind of agricultural machinery used for dense planting in corn fields. These seeders are designed to increase the number of effective corn plants through reasonable dense planting technology, thereby improving yield and economic benefits.

[0003] For example, a roller seeder recorded in the patent with patent announcement number CN219961324 U, when a person pushes the frame forward by hand, the obstacle clearing component will clear obstacles such as weeds, branches or stones on the surface at the front end. Compared with the existing method in which the seeding wheel directly moves at the front end and sows, it can avoid the seeding wheel from being entangled or damaged after contacting with debris while moving.

[0004] However, the above case has the problem of being unable to loosen the soil. Due to the difference in the softness of the soil during sowing, the soil is hard in the land that has been exposed to the sun for a long time, which makes it impossible to insert the sowing port of the sowing wheel into the soil, thereby making it impossible to sow seeds, or the sowing distance is shallow. In addition, when the existing seeder is not in use or needs to be moved after sowing, the wheel sowing disc is in direct contact with the hard ground, which can easily cause damage to the wheel sowing disc.

[0005] Based on this, a corn dense planting sowing and metering device is now provided, which can eliminate the disadvantages of the existing devices. Utility Model Content
