Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery, in particular to a seed spot sowing device. Background Art

[0002] Spot sowing is the process of sowing in holes according to a certain row-hole spacing, also known as hole seeding. Spot sowing is done according to the appropriate row and plant spacing for the crop to ensure density, uniform seed penetration depth, neat seedling emergence, small seed usage, and convenient centralized fertilization and field management. Spot sowing is more labor-intensive and is suitable for large-grain crops and areas with poor fertilizer and water conditions in hilly and mountainous areas.

[0003] At present, most seed sowing devices require manual pressure to insert the bottom of the seed sowing device into the ground for sowing, which is inefficient. In addition, the existing seed sowing devices do not have the function of loosening the soil. Since the soil may be relatively hard, direct sowing without loosening the soil may cause the seeds to be wrapped too tightly in the soil, resulting in airtightness and seed rot and failure to germinate.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. The seed sowing device drives the turntable to rotate through a long-axis motor, and pushes or pulls the lifting adjustment rod through a connecting rod to perform reciprocating up and down linear motion.

[0013] 2. This seed sowing device drives the main pulley to rotate through the output shaft of the long-axis motor when it is running. The main pulley drives the secondary pulley to rotate through the transmission belt, so that the loosening claw rotates to loosen the soil, which is convenient for the seed storage tube to be inserted into the soil. After the sowing is completed, the leveling roller presses the soil down to make it flat. When sowing, the soil is loosened to facilitate the seeds to be buried in the soil and improve the survival rate of the seeds. BRIEF DESCRIPTION OF THE DRAWINGS
