Machine to sow seeds

Types of machines to sow seeds

A machine to sow seeds is a planting device that helps farmers and gardeners to efficiently and deeply put seeds into the soil. These machines can be manual, animal-powered, or machine-powered. Historically, seeds were thrown by hand or scattered by hand-held wooden devices, but modern devices allow for precise planting.

The basic principle of all planting devices is to uniformly distribute seeds over an area, allowing the right amount of space between each seed for optimum growth. Sharing can be done by gravity, air, or mechanical systems. Gravity systems use a hopper to uniformly spread seeds through an adjustable opening. Air systems use a fan to blow seeds through tubes into the soil. Mechanical systems release seeds from cassettes or discs into the soil.

Pre-adapted seeders are spreaders that can be used without any prior preparation. In contrast, adaptable seeders are spreaders that can be used after adjustments have been made to enable them to be used effectively. The former should be preferred in cases that require immediate seeding and the latter in cases that are agricultural and industrial.

Modern seeders can be divided into the following types:

• Seed drills: The backbone of agricultural seed planting machinery, these multifunctional machines, usually towed behind a tractor, prepare the soil, fertilize it, and plant seeds in a single pass.
• No-till planters: They are specialized seed drills that plant seeds directly into soil without prior tilling or preparation. By preserving crop residue, no-till planters improve soil health and decrease soil erosion.
• Broadcast seeders: Broadcast seeders, which may be pushed, towed, or pulled and are powered by gravity or mechanically, are used to sow seeds over a wide area uniformly. They are applicable where there is little variation in altitude and relief, are frequently used in pasture and turf management, and can ideally be used for fortification without prior land preparation.
• Airseeders: A type of seeder that utilizes air pressure for soil distribution. Airseeders can be tow-behind or pull-behind designs and are ideal for high-acreage seeding operations.
• Broadcast sprayers: Incorporating seeds into a solution and spreading them over the intended area, broadcasting sprayers find applications in areas with minimal soil disturbance requirements and can be especially valuable in scenarios demanding rapid seeding for erosion control, habitat restoration, or rehabilitation of disturbed lands.
• Rice Transplanters: Specialized agricultural machines designed to automate the planting of rice seedlings in flooded paddies with precision and efficiency. In various configurations and types, they usually comprise a seedling tray container, a feed mechanism, planting tools, and a chassis.
• Vegetable Seeders: Tractors designed to plant vegetable crops with high accuracy and efficiency are often characterized by adjustable row spacing, interchangeable seed disks, and variable planting speeds to accommodate different vegetable sizes and planting densities.
• Smart Seeders: Modern agricultural practices are increasingly reliant on smart seeders and precision planters that make use of electronic sensors, GPS technology, and advanced computing systems to facilitate the accurate and efficient planting of seeds with minimal waste and maximum utilization of the area to be seeded.
• Crop-specific seeders: These seeders are specifically tailored to ensure the precise sowing of particular crops and exhibit the capacity to accurately space and place seeds at the desired depth, thereby enhancing the planting efficiency and improving the quality of the plantation.

Maintenance of Seed Sowing Machines

Reasonable maintenance of the sowing machine can ensure its normal operation and stability, and improve its service life. Here are a few tips for seed sowing machine maintenance:

• Regular Inspection: Operators should develop routine inspection schedules to identify potential problems early. Check components such as belts, chains, gears, and bearings for signs of wear, damage, or looseness. Pay attention to adjusting and tightening the seed sowing machine parts as per the prescribed standards to ensure proper seed distribution, stability, and accuracy. Meanwhile, check critical components for sealing, moisture, air, and soil ingress to avoid overexposure and contamination.
• Cleaning: Operators should develop routine cleanup schedules. Cleaning up the surface, soil, and seeds of fertilizers can effectively avoid cross-seeding and soil aridity in different fields. Additionally, operators should pay attention to the appropriate cleaning methods, use the right tools, support the right techniques to avoid damaging the sowing machine.
• Before and after use, operators should promptly replenish lubricants and oils, choose the right kinds of oils, and make careful use to ensure that the seed sowing machine moves freely and works well.
• Storage: During idle periods, use cloth or other relevant materials to cover motor seeds to separate them from the external environment. If necessary, find a sheltered, level place to store them to keep them safe from the elements. At the same time, further cleaning and inspection should be carried out to ensure the seed sowing machine is in good condition the next time it is used for sowing.
