Description
Technical Field
[0001] The utility model belongs to the technical field of crop seeding equipment, and particularly relates to a corn seeder. Background Art
[0002] Corn is an important food crop widely planted globally and is also affectionately called maize, corn cob, or sweet corn, etc. It originated in Central and South America and has since spread to become part of the food cultures around the world. Corn is a tall annual herbaceous plant with developed root systems and thick stalks, broad leaves, and unisexual and monoecious flowers. Among them, a corn seeder is a planting machine that uses corn seeds as the seeding object and may also take into account other crops such as soybeans.
[0003] The utility model patent with the publication number of "CN221010745U" discloses a multi-groove corn seeder, including a bottom plate. A storage box is fixedly connected to the upper surface of the bottom plate. A feed inlet is fixedly connected to the top surface of the storage box. A first motor is fixedly installed on the outer side surface of one side of the storage box. A first rotating shaft is fixedly connected to the output end of the first motor. The first rotating shaft penetrates through the storage box. A feeding roller is fixedly connected to the surface of the first rotating shaft. Feeding grooves are equidistantly arranged on the surface of the feeding roller. A sowing nozzle is fixedly connected to the bottom box wall of the storage box. Both ends of the sowing nozzle penetrate through the bottom box wall of the storage box and the bottom plate respectively. In the utility model, through the setting of the first motor, plowshare, feeding roller, and sowing channel, multi-groove simultaneous planting can be carried out, effectively improving the planting efficiency and making the planting more uniform.
[0004] Although the above-mentioned utility model can carry out multi-groove simultaneous planting through the setting of the first motor, plowshare, feeding roller, and sowing channel, effectively improving the planting efficiency and making the planting more uniform, when sowing corn, the plowshare is a component that directly contacts the soil and bears wear. After long-term use, it will experience wear or damage. When the plowshare wears to a certain extent, if it cannot be replaced in time, it will affect the operation depth and efficiency of the seeder. Moreover, during the sowing process, impurities such as soil and weeds are likely to adhere to the plowshare. If it cannot be disassembled, these impurities will be difficult to completely remove. Long-term accumulation may lead to a decline in the performance of the plowshare and even affect the overall performance of the seeder. At the same time, it is difficult to adapt to various plot conditions and cannot meet the specific requirements of different crops, restricting the application range of the seeder. Content of the Utility Model
[0005] In view of the problems mentioned in the background art, the purpose of the present utility model is to provide a corn seeder to solve the problems that when sowing corn, the plow blade directly contacts the soil and bears the worn parts, which will be worn or damaged after long-term use. When the plow blade is worn to a certain extent, if it cannot be replaced, it will affect the working depth and efficiency of the seeder. Moreover, during the sowing process, impurities such as soil and weeds are easily attached to the plow blade. If it cannot be disassembled, these impurities will be difficult to completely remove, and long-term accumulation will lead to a decline in the performance of the plow blade and a shortening of the service life, etc.
