Two new types of straw comprehensive utilization equipment

In early September this year, two innovative straw utilization machines were showcased at a straw comprehensive utilization site in Hebei Province, catching the attention of attendees. One was the Huitian corn stalk harvester from Zhao County Agricultural Machinery Factory in Hebei, and the other was the 4JQ series straw chopping silage machine developed by Shijiazhuang Agricultural Machinery Co., Ltd. Here's a detailed introduction to both devices. The 4YG 2A/3A corn stalk harvester features a vertical front hydraulic suspension system, making it compatible with small four-wheel tractors ranging from 12 to 18 horsepower. The machine consists of a power transmission gearbox, frame, reversing gearbox, cutter shaft, upper and lower straw conveying systems, and a hydraulic lifting mechanism. Equipped with conveyor guide plates and harvesting rods, it efficiently lays down corn stalks in an orderly manner. It can also be used for harvesting crops with large roots and tall straws, such as sorghum, sugarcane, and sunflower. Its simple design ensures high reliability and makes it ideal for silage operations on a large scale. Key technical specifications of the 4YG 2A and 3A models include: - **Supported Power**: 12–18 HP - **Number of Cutter Shafts**: 2 (for 4YG 2A), 3 (for 4YG 3A) - **Number of Cutters**: 8 (4YG 2A), 12 (4YG 3A) - **Spindle Speed**: 350 rpm - **Harvesting Rows**: 2 (4YG 2A), 3 (4YG 3A) - **Cutting Radius**: 250 mm - **Productivity**: 6–10 mu/h (4YG 2A), 8–12 mu/h (4YG 3A) - **Weight**: 160 kg (4YG 2A), 200 kg (4YG 3A) - **Overall Dimensions**: 1360×450×1000 mm (4YG 2A), 1860×450×1000 mm (4YG 3A) - **Remaining Height**: 50–120 mm - **Cutting Width**: 110 cm (4YG 2A), 160 cm (4YG 3A) The 4JQ series straw chopping silage machine is a new generation of equipment designed for efficient straw processing. It can be paired with tractors ranging from 50 to 100 horsepower and performs chopping, throwing, and collection of upright straw in a single operation. The chopped straw is fine and can be directly used for silage after being collected by a transport vehicle. Additionally, the machine allows for partial removal and return of straw to the field, maximizing the use of existing straw returning machinery and offering multi-functional capabilities. Technical parameters of the 4JQ series include: - **Model**: 4JQ-1.5, 4JQ-2, 4JQ-2.5 - **Dimensions**: 160×196×240 mm, 160×250×250 mm, 170×300×250 mm - **Working Width**: 1500 mm, 2000 mm, 2500 mm - **Supported Power**: 50–70 HP, 65–100 HP, 80–100 HP - **Throwing Height**: 2.5 m (for 4JQ-1.5 and 4JQ-2), 3 m (for 4JQ-2.5) - **Number of Tools**: 10, 13, 16 These machines represent significant advancements in agricultural technology, helping to improve efficiency and sustainability in straw utilization across Hebei Province and beyond.
