Two new types of straw comprehensive utilization equipment

In early September this year, two innovative straw utilization machines were showcased at a field demonstration in Hebei Province, attracting considerable attention from participants. These new technologies are set to revolutionize the way agricultural waste is managed and repurposed. The first machine is the Huitian brand corn stalk harvester, developed by Zhao County Agricultural Machinery Factory in Hebei. The second is the 4JQ series straw chopping silage machine, produced by Shijiazhuang Agricultural Machinery Co., Ltd. Both models offer advanced features that enhance efficiency and versatility in straw processing. The 4YG 2A/3A corn stalk harvester is designed with a vertical front hydraulic suspension system, making it compatible with small four-wheel tractors ranging from 12 to 18 horsepower. This machine consists of several key components, including a power transmission gearbox, frame, reversing gearbox, cutter shaft, and various conveying systems for the straw. The conveyor guide plates and harvesting rods on the frame ensure that the corn stalks are neatly laid on the ground, making it suitable not only for corn but also for other crops like sorghum, sugarcane, and sunflowers. Its simple structure and high reliability make it ideal for use in straw silage operations across different regions. Key technical specifications of the 4YG 2A and 3A models include: - Supporting Power: 12–18 HP - Number of Cutter Shafts: 2 (for 4YG 2A) / 3 (for 4YG 3A) - Number of Cutters: 8 (for 4YG 2A) / 12 (for 4YG 3A) - Spindle Speed: 350 rpm - Harvesting Rows: 2 (for 4YG 2A) / 3 (for 4YG 3A) - Knife Radius: 250 mm - Productivity: 6–10 mu/h (for 4YG 2A) / 8–12 mu/h (for 4YG 3A) - Total Weight: 160 kg (for 4YG 2A) / 200 kg (for 4YG 3A) - Overall Dimensions: 1360 × 450 × 1000 mm (for 4YG 2A) / 1860 × 450 × 1000 mm (for 4YG 3A) - Remaining Height: 50–120 mm - Cutting Width: 110 cm (for 4YG 2A) / 160 cm (for 4YG 3A) On the other hand, the 4JQ series straw chopped silage machine represents a new generation of equipment designed for efficient straw processing. It can be paired with tractors ranging from 50 to 100 horsepower, enabling one-step operation for cutting, throwing, and collecting upright straw in the field. The finely chopped straw can be directly used for silage after being gathered by a collection truck. Additionally, it allows for partial removal of straw and direct chopping for return to the field, maximizing resource utilization. This multi-functional design makes it compatible with existing straw returning machines, enhancing its practicality and cost-effectiveness. Technical parameters of the 4JQ series models are as follows: - Model: 4JQ-1.5, 4JQ-2, 4JQ-2.5 - Dimensions: 1601×962×40 mm, 1602×502×50 mm, 1703×002×50 mm - Operating Width: 1500 mm, 2000 mm, 2500 mm - Supporting Power: 50–70 HP, 65–100 HP, 80–100 HP - Height of Throwing: 2.5 m, 2.5 m, 3 m - Number of Tools: 10, 13, 16 These machines are not just tools; they are essential steps toward sustainable farming practices, reducing waste and increasing productivity in the agricultural sector. Their introduction marks a significant advancement in the comprehensive utilization of straw, offering farmers more efficient and eco-friendly solutions.
