4 Row Pneumatic Carrot Seeder

This suction-type carrot seeder is equipped with a vacuum system. It is also a multifunctional machine featuring a real-time monitoring system that allows the operator to observe seed intake from the cab. Additionally, the machine can precisely control plant spacing and seeding depth, making it a smart and precise solution for modern carrot cultivation.

Seed Treatment: For seeds that are very small or irregular in shape, it is recommended to apply a seed coating to increase their sensitivity to oxygen absorption and improve germination uniformity.
Field Conditions: Excessively wet soil may affect seeding performance; it is recommended to perform seeding when soil moisture is optimal.
Calibration: Perform a no-load calibration before seeding to verify seed distribution uniformity and seeding depth settings.

This pneumatic suction-type carrot seeder is the result of robust R&D capabilities and was jointly developed by the Shandong Provincial Enterprise Technology Center and the Qingdao Municipal Engineering Research Center for Vegetable Seeding Equipment. The company maintains long-term industry-academia-research partnerships with institutions such as the Nanjing Institute of Agricultural Mechanization (Ministry of Agriculture and Rural Affairs) and Qingdao Agricultural University. With over 40 invention patents, this pneumatic suction-type carrot seeder is a precision vegetable seeding solution that has been proven technically mature and rigorously tested.
   
The pneumatic suction-type carrot seeder is part of a comprehensive product portfolio. Core products include pneumatic suction-type carrot seeders, onion seeders, and other vegetable seeding machinery, complemented by rotary tilling and ridging combination machines, seeders, and auxiliary equipment. Together, these products cover the entire mechanized process of vegetable production.
The pneumatic suction-type carrot planter also benefits from advanced manufacturing capabilities. The manufacturing facility is certified to the ISO 9001 quality management system and CE standards, ensuring that every pneumatic suction-type carrot planter meets strict quality and safety requirements.

This pneumatic carrot seeder is equipped with an intelligent pneumatic seeding system. It features a pressure gauge that monitors fluctuations in negative pressure in real time, keeping pressure fluctuations within the normal range. The modular seed tray design allows for the replacement of different-sized pneumatic seed trays in just 2 minutes.
This pneumatic carrot seeder also integrates an all-terrain adaptation system. The combination of hydraulic shock absorption and a four-bar contour-following design ensures consistent seeding depth across all types of terrain.
In addition, this pneumatic carrot seeder is equipped with an intelligent monitoring system. This system provides real-time monitoring of the seeding status for each row, making this pneumatic carrot seeder a truly data-driven, precision vegetable seeding solution.

Q: What is the core distinction between pneumatic and mechanical seed drills?
A: The air suction carrot planter uses negative pressure to capture seeds for 'non-contact' sowing. Three advantages:

• Precision: Single-seed rate >96%, reducing seed waste and thinning labour.
• Adaptability: No strict shape constraints, ideal for irregular seeds like carrots.
• Seed protection: No mechanical compression, zero damage to coated seeds.

Q: How does it ensure uniform sowing depth on complex terrain?
A: Independent contour-following: Four-bar linkage adjusts to terrain.

• Pressure compensation: Hydraulic damping adjusts downward pressure based on soil hardness.
• Slope design: Optimised centre of gravity for stability up to 15 degrees.

Q: How to adjust parameters according to seed size?
A: For the air suction carrot planter:

• Replace seed tray: Choose aperture for seed size (1.5–5.0 mm, six options).
• Set negative pressure: 4–8 kPa via control panel.
• Calibrate cleaning brush: Adjust gap to 0.5–1.0 mm.

Q: How to investigate inconsistent sowing depth?
A: Follow this sequence:

• Check ground levelling: Ensure elevation variation <5 cm.
• Calibrate contour-following: Verify spring preload row by row.
• Assess coulter wear: Replace if variation exceeds 15%.
• Adjust speed: Maintain 3–6 km/h.

Q: What are key routine maintenance considerations?
A: Follow the 'Four-Step Method':

• Clear seed residue: Empty hopper, clean suction holes with air gun.
• Remove soil deposits: Clean coulters and packer wheels.
• Clean filtration: Wash fan intake filter after each shift.
• Check fastening integrity: Inspect bolt torque at suspension and transmission points.
