In the process of land preparation and sowing in large-scale agricultural production, the efficiency and quality of operations directly affect the final planting income. SITERA 330 compoundStrip broadcasting machinePaired with heavy-duty HR seriesDrive rakeThe combination scheme of land preparation and sowing can be completed in one go, which effectively reduces the number of work cycles and lowers the cost compared to the traditional mode of separating harrowing and sowing operationsTractorThe frequency of soil compaction can better protect soil moisture and lay the foundation for increasing production and income in the future. Today, we will provide a comprehensive explanation of the performance details of this equipment combination from the practical perspective of actual homework.
1、 Adaptability of core parameters
The SITERA330 compound seeder has a basic operating width of 3 meters. When used in conjunction with the HR 3004 drive rake of the same operating width, it supports two optional configurations of 20 rows/24 rows for sowing, with corresponding row spacing of 15 centimeters and 12.5 centimeters, respectively. It can adapt to the dense planting agronomic requirements of different crops. The standard seed box capacity of the equipment is 600 liters. After installing a height increasing plate, the capacity can be expanded to 900 liters, greatly reducing the frequency of seed addition during large-scale planting operations and improving continuous operation efficiency.
2、 Patent HELICA seeder performance
The patented HELICA seeder equipped on this device adopts a unique spline spiral structure to ensure that every seed can be accurately transported, avoiding the problem of missed or replayed seeds from the root.
It replaces the traditional gap adjustment design that requires the replacement of multiple components with a central fine adjustment screw. Operators only need to rotate the screw to quickly adjust the planting gap, and a single system can break through the seed size limit. There is no need to separately purchase specialized seeders for different types of crops such as small grains and large seeds. It not only meets the planting needs of all categories of crops, but also significantly reduces the investment and subsequent maintenance costs of the equipment. Based on the advantages of the SITERA 330 compound strip sowing machine's full field adaptation seeding system and stable seeding structure, field operations in the Sichuan Plain region have verified that this equipment not only efficiently completes conventional field strip sowing operations, but also has excellent adaptability for planting crops with different particle sizes and planting requirements such as rice and soybeans. It can meet the seeding needs of multiple crops without the need to replace exclusive accessories, truly realizing one machine for multiple purposes, helping users greatly improve the efficiency of multi category rotation operations, reduce the purchase investment of multiple specialized agricultural machinery, and effectively reduce the cost of using agricultural machinery throughout the entire planting process.
3、 Advantages of sowing individual units with parallel four-bar linkage structure
The equipment adopts a parallel four-bar linkage structure for seeding units, equipped with a spring pre tensioning structure, which can always maintain a constant ground pressure. All sowing units can independently float with the terrain, even on uneven plots or slopes, and can stably cope.
This structure is also equipped with a contour wheel linkage depth limiting mechanism, which is made of specially treated materials to achieve a perfect fit between rigidity and toughness. It can effectively ensure uniform and consistent sowing depth, greatly improve sowing accuracy, and significantly extend the service life of the entire individual structure.
4、 SEEDFLEX Double Groove Disc Design Features
SITERA 330 adopts SEEDFLEX dual slotted disc design, with two 350mm large discs set at a 41mm offset angle, forming a super large overlapping area, which can completely block soil or crop residues from lingering at the slotted parts. Even if the disc radius wears down to 15 millimeters, it can still maintain an effective overlapping state.
At the same time, this offset angle design can also reduce the problem of accidental coverage of the front seeding ditch by the soil thrown after high-speed operation. The equipment has strong adaptability to the ground conditions, and can operate stably on various complex plots such as sticky soil and sandy soil, ensuring uniform seed sowing and effectively improving seedling emergence rate.
5、 Practical features of supporting HR series drive rake
The HR series heavy-duty drive rake, which is compatible with SITERA 330, can be mounted on high-powered tractors and effectively improve the overall efficiency of land preparation operations. The driving rake adopts a three-point hanging structure, which makes the whole machine more maneuverable. When farmers transition between different plots, it is more convenient and flexible to operate on the road.
In response to the common problem of entanglement of auxiliary materials encountered by farmers during their operations, the rake seat of this driving rake is specially equipped with anti entanglement rings, which can effectively prevent drip irrigation belts and plastic films from being trapped in the gaps of the equipment, prevent oil seals or bearings from being damaged by foreign objects, reduce the probability of equipment failure and shutdown, and extend the service life of core components.
This set of land preparation and sowing combination equipment, from optimizing the operation process to designing the details of core components, is designed around the pain points of actual agricultural production. It can reduce production input while ensuring the quality of operation, and is a reliable choice for large-scale planting to improve planting efficiency.
