Fertilizer Spreader

1.1 Structure and Weight
All models in the series adopt an enclosed box structure, which has excellent protective performance. It can effectively prevent fertilizer from getting damp and scattered, ensuring a clean and efficient fertilization process. In terms of total weight, the six models show a gradient distribution, gradually increasing from 1230Kg to 2860Kg.
Lightweight models (1230Kg, 1300Kg) are suitable for flexible transportation and operation in small and medium-sized plots. Heavier models (1570Kg, 1600Kg, 2540Kg, 2860Kg) have a more stable body, making them suitable for long-term operations in large-scale contiguous plots.
1.2 Dimension Parameters
•Overall Size: The overall sizes of the six models vary significantly. The smallest specification is 4.4×1.97×1.7m, and the largest reaches 6.5×2.75×2.4m. You can choose flexibly according to plot width, transportation channel size, and operation space, balancing transportation convenience and operation coverage.
•Carriage Size: Corresponding to the overall size design, the carriage sizes range from 2.75×1.75×0.9m to 4.4×2×1.5m. Carriages of different capacities can meet different fertilization volume needs. Small carriages are suitable for split fertilization in small plots, while large carriages reduce the frequency of frequent fertilizer replenishment and improve the efficiency of large-scale operations.

2.1 Wheelbase and Traction Length
•Wheelbase: Some specifications of the series have marked wheelbases, which are 1.7m, 1.78m, 2.03m, and 2.2m, respectively (one specification has no wheelbase marked). The reasonable wheelbase design ensures stable vehicle operation, reduces vibration during operation, and ensures fertilizer application uniformity.
•Traction Length: It is uniformly 1m, 1.28m, or 1.3m. The short traction length (1m) is suitable for turning and reversing in small plots. The long traction length (1.28m, 1.3m) is suitable for large tractors, improving stability in long-distance operations.

2.2 Tire Configuration
Tire models are accurately matched according to the machine specifications:
•Small and medium-sized models use 11.5/80-15.3 and 14-17.5 tires, which have good ground adaptability and are suitable for ordinary farmland operations.
•Large-sized models are equipped with 16/70-20 and 500/60-22.5 tires, which have a stronger load-bearing capacity. They can cope with operations in complex plots (such as muddy and undulating plots) and reduce tire wear.

3.1 Operation Method
The series of models adopts the horizontal auger spreading method by default, which has high spreading uniformity and can meet the fertilization needs of most granular fertilizer and powdered fertilizer. At the same time, it supports customized configurations, including double-disc rear spreading, double vertical augers, and side spreading. It can be flexibly adjusted according to crop planting row spacing and fertilization position requirements (such as inter-row fertilization and root fertilization), and is suitable for fertilization scenarios of different crops such as corn, wheat, and rice.
3.2 Spreading Width and Conveying Method
•Spreading Width: Some models have marked spreading widths, covering two ranges of 8-12m and 8-15m. Wide-range spreading (8-15m) can greatly increase the operation area per unit time, reduce the number of operation trips, and is suitable for large-scale planting. The 8-12m spreading width balances uniformity and flexibility, and is suitable for medium-sized plots.
•Conveying Method: It uniformly adopts a chain conveyor, which has a stable conveying process with low risk of blockage. It can ensure the uniform falling speed of fertilizer, and cooperate with the spreading mechanism to achieve uniform fertilization, avoiding local excessive or insufficient fertilizer amount caused by uneven conveying.

According to their own specifications, the series of models clearly defines the supporting power requirements, forming a clear power gradient:
•Small and medium-sized models (total weight 1230Kg, 1300Kg, 1570Kg, 1600Kg) need to be matched with tractors with more than 50 horsepower or 60 horsepower. They are compatible with common small and medium-sized agricultural power equipment, reducing equipment investment costs.
•Large-sized models (total weight 2540Kg, 2860Kg) need to be matched with four-wheel tractors with more than 80 horsepower or 120 horsepower. Sufficient power support ensures that large-sized models maintain stable efficiency during heavy-load and wide-range operations, avoiding operation jams caused by insufficient power.
In summary, through structural optimization, gradient specification design, flexible operation configurations, and accurate power matching, this series of fertilizer spreaders can meet the fertilization needs of different planting scales and crop types. It effectively improves fertilization efficiency and uniformity, and provides strong support for quality improvement and efficiency enhancement in agricultural production.
