Description

This disclosure relates to the field of agricultural equipment, and more specifically to seed planting equipment. The following background information on the present invention is relevant to this disclosure, but is not necessarily prior art. Grains and cereals, especially rice, are typically cultivated by transplanting seedlings or sowing seeds. Transplanting seedlings is labor-intensive, involving the preparation of seedling mats after a certain number of days, either with the help of a seeding device or manually. Direct sowing is relatively advantageous because it avoids repeated waterlogging and subsequent soil degradation. Furthermore, at least 35–40% of water is saved, thereby reducing production costs. Additionally, energy, fuel, labor shortages, forced labor, and seeds are also saved. Direct sowing is typically performed with the help of a seeding drill or a precision pneumatic seeder. However, seeding drills require highly skilled labor to avoid seed loss. Precision pneumatic seeders, on the other hand, are impractical for sowing rice seeds, especially germinated seeds, because they require uniform seed shape for efficient sowing. Furthermore, sowing germinated seeds is a difficult task because handling them without damage is challenging. Conventional seeding devices (mentioned above) are inadequate for handling germinated seeds, and in most cases, seeds are damaged during distribution, rendering the entire sowing operation useless. Moreover, most seeding devices are manually operated. Furthermore, conventional seeding devices require additional devices to systematically create hills and valleys in the field to significantly reduce weeds and increase yield. As a result, the time and effort required for seed planting are greatly increased. Conversely, scattering dry seeds does not allow the use of germinated seeds and therefore hinders the potential for seed growth. Therefore, there is a need for a seeding device that can mitigate the aforementioned shortcomings. the purpose Some of the objectives of this disclosure that at least one embodiment of this specification satisfies are as follows: The purpose of this disclosure is to provide a grain seeding apparatus. Another object of this disclosure is to provide a grain seeding apparatus that allows for easy handling of germinated seeds. Another object of this disclosure is to provide a grain seeding apparatus that can create hills and valleys in a field, thereby saving the time, cost, and labor required to create hills and valleys. Another object of this disclosure is to provide a grain seeding apparatus capable of distributing seeds of any various lengths. Another object of this disclosure is to provide a grain seeding apparatus that avoids repeated waterlogging and subsequent soil degradation. Another object of this disclosure is to provide a grain planting apparatus that saves water, production costs, energy, fuel, labor shortages, forced labor, and seeds.
