Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of seed sowing, especially relates to corn hybrid seed sowing and soil covering device. BACKGROUND

[0002] Corn hybrid seed is the first generation seed produced by hybridization of corn varieties with different genetic characteristics. The main purpose of this hybridization method is to combine the excellent genetic characteristics of both parents to create new varieties that perform better in growth rate, yield, stress resistance, quality, etc. Corn hybrid seed is an important resource in modern agriculture and has important significance for improving corn yield, improving quality and enhancing stress resistance. The sowing and soil covering device is a device used to cover soil on seeds or seedlings during sowing to protect them from the external environment.

[0003] According to the search, the Chinese patent with publication number CN215301470U discloses a corn hybrid seed sowing and soil covering device. Many seed sowing and soil covering devices will bounce in the furrow due to the unevenness of the field during movement in the field. This will affect the sowing position and affect the sowing accuracy, making it inconvenient for later mechanized management. Therefore, a buffer shock absorbing roller is arranged on the left and right sides of the device bottom plate to provide buffer shock absorbing effect during movement. The inclined rod improves the support strength and reduces the impact of vibration when bouncing occurs, ensuring stable sowing and facilitating later mechanized management.

[0004] The above-mentioned seed sowing and soil covering device is convenient for shock absorption during movement. However, due to the differences in soil texture and moisture content, the existing technology uses a soil covering plate fixed at the bottom of the device, which is not convenient for adjusting the soil covering angle of the soil covering plate, reducing the adaptability of the soil covering plate to different soil environments and reducing the adjustability of the soil covering plate.
