1、 Overall appearance: 6950 * 3000 * 4600mm (external dimensions)

2、 Power system

1. Supporting engine (Shangchai brand), with a speed of 2200 revolutions per second, super high horsepower, powerful, fuel-efficient, and easy to maintain. Shangchai GuoIII electronic fuel injection diesel engine, the power system adopts Shangchai GuoIII electronic fuel injection diesel engine (275 horsepower), with greater power reserve; Electronic fuel injection diesel engines are more fuel-efficient, environmentally friendly, and have greatly improved fuel efficiency, lower failure rates, and higher reliability.

2. Heat sink: The water tank and intercooler are placed separately, and the fan is used for heat dissipation, resulting in good heat dissipation effect. The air filter is placed at the top of the body for easy cleaning. We have adopted a water tank with a larger heat dissipation area, a rotating cover for the water tank, and an air filter (with the addition of a pre filter). Good adaptability to oil products, low fuel consumption, fast overload response speed, and high reliability.

3. Diesel Tank: A 300 liter super large diesel tank increases range!

3、 Harvesting system

1. Double disc cutting table (standard, net cutting width 2650mm): The cutting disc at the bottom of the cutting table adopts a blade edge that has been specially treated to improve wear resistance, extend blade service life, and reduce energy consumption. The cutting height is ≤ 15cm, and it is equipped with a special shaped scraper. The sharp scraper can scrape the cutting edge to pieces, accelerate cutting edge decay, and better protect the tire. The harvester has a strong harvesting ability for fallen crops, and the fallen straw can be harvested as long as it can be transported to the disc by the fork in front of each disc. Corn planting with a row spacing of 400mm-550mm can harvest five rows; Corn planting with a row spacing of 600mm-700mm can harvest four rows. ）

2. Reciprocating cutting table (optional): feeding is not in line. Low stubble, suitable for low growing corn crops such as grass and lodging, and can also harvest barley.

3. Feeding device (flattening bridge): consisting of five feeding rollers, the upper front and rear feeding rollers can float to adapt to different feeding amounts, and the lower part has three fixed feeding rollers to flatten the fed straw. Advanced feeding device design integrates feeding and flattening to form a stable feeding flow.

4. Chopping roller mechanism (shredding device): mainly composed of a shredding drum, a moving blade, a fixed blade, a concave plate device, etc. The blade roller design of this machine adopts advanced foreign technology, with a drum combined blade. The moving blade is arranged in a herringbone shape on the drum, and the blade edge of the moving blade is coated with alloy steel, which is maintenance free, directly reduces power, has good shredding effect, and can continuously ensure cutting quality. The cutting edge of the fixed blade has undergone special treatment and is embedded with hard alloy. Improved wear resistance, reduced power consumption, evenly distributed force when chopping straw, and extended blade lifespan. Cutting length of 9-22mm, precise and perfect feed length.

New fixed knife quick adjustment mechanism: It can quickly and conveniently adjust the fixed knife, ensure the gap between the moving and fixed knives, and improve the quality of shredding.

5. Grain crushing device (kneading board+roller type)

Grain crushing device: consisting of two toothed rollers that rotate at high speeds with different speeds and directions of rotation. The material is crushed through the narrow gap between the two rollers of the grain crusher. The large-diameter rolling roller has a good rolling effect, which is conducive to improving work efficiency and the quality level of shredded materials. By using a large amount of material, the surface of the rolling roller is not sticky or rusted. Change the degree of crushing by adjusting the gap (1-6mm). The factory condition is 3mm, and the tooth surface has undergone heat treatment and surface treatment. The transition interface can be replaced when the seeds are not crushed

6. Throwing device:

Adopting a high-power throwing fan, the structure is simple and practical, and the throwing is particularly fast. The feeding arm for conveying feed can rotate 270 °, fully hydraulic control, and can follow the collection truck in left, right, and rear directions, with strong adaptability and improved harvesting efficiency. Its throwing height range is 4.9-5.6 meters, which can adapt to higher material receiving vehicles and meet the needs of road opening operations. The new throwing arm changes the rotating base of the throwing arm to horizontal, ensuring that the spraying height of the rear and side parts is consistent, and improving the feeding force of the rear part following the vehicle.

The front end of the throwing arm is equipped with a feeding probe, which can monitor the real-time status of the material being thrown onto the feeding vehicle, making the operation more convenient.

4、 Walking system (chassis)

Adopting an independent electronic hydraulic radiator+hydraulic drive pump+hydraulic motor+gearbox+side reducer+driving wheel walking mode, the plunger pump and motor are selected from internationally renowned brands Eaton and Danfoss, with the following characteristics: large displacement, strong power, and high reliability; No clutch, no need to shift gears during operation, improving driving comfort; Continuously variable transmission, easy to control speed, fast turning, convenient operation, and high work efficiency. The stability of the driving wheels is good, with large wheel drive and 15-24 herringbone high flower tires (small wheel steering, 10.0 | 75-15.3 off-road tires) to reduce the compaction of the working ground, ensuring no ditch pressure. The wide tires have a large diameter in the front and rear tires, reducing the ground pressure ratio. It has good passability, strong ability to pass through wet and damp areas after rainy days, strong ability to climb slopes and cross hills, and good regional adaptability. The chassis is produced by a professional manufacturer with high reliability. The chassis is a self-propelled special chassis, which is the same as the chassis used in Deere products.

2. Steering axle (can be equipped with four-wheel drive function)

5、 Driver's cabin

1. The cab is fully curved, with good sealing and comfortable space, equipped with a passenger seat facing the rear. Advanced symmetrical arrangement, good driving visibility, panoramic view, accurate vision, suitable for observing the cutting platform, very safe and efficient for loading trailers. The new driver's cab has been enlarged and improved with both side doors and rear glass, enhancing the visibility of passengers inside the cab. The driver's cabin can be equipped with air conditioning for high comfort; The machine is equipped with an imported automatic lubrication device, and the bearings in key parts can achieve automatic oil lubrication, reducing the maintenance time of the machine operator and improving the reliability of the machine.

2. An automatic chain lubrication system can be installed to ensure continuous maintenance of key parts of the entire machine, with a longer service life and more reliable operation. High quality hydraulic components ensure reliable performance and flexible and convenient operation. The hydraulic system consists of two subsystems: steering and solenoid valve control. The use of solenoid valves and control handles can improve the driver's handling and comfort, and enhance work efficiency. Provide an external controller that can be operated outside the cab. Common operations are controlled on a multifunctional controller, making it easy to operate.

3. Paired with high-definition reversing camera, it is more convenient and safe! Visualization, intelligence, and reasonable electrical and lighting design ensure that you work without obstacles at night. The electrical system lighting design is reasonable, and the front lighting can illuminate the entire operating range of the cutting table; The rear lights can cover the outlet of the feed delivery drum and operate normally at night.

Upgraded version, providing you with a more efficient harvesting experience!
