Leweinong 4YZQ-4B self-propelled stem and ear harvestingCorn harvesterIt is a new type of multi-functional machine with one device; A product that can be used for full storage in the early stage and yellow storage in the later stage to make the working cycle longer and the user benefit higher. The car has a short and compact body, a small turning radius, a length of 7.2 meters, flexibility and reliability, and can adapt to large, medium and small terrain. The car is 3.4 meters high and 2.6 meters wide, which provides better passability and stability. It is also equipped with front and rear cameras to make it easier for agricultural machinery operators to observe the surrounding situation of the vehicle. This machine adopts a double layered cutting platform (the upper cutting platform is the corn cutting platform, and the lower cutting platform is a relatively mature wheat cutting platform) to better separate corn and straw. The picking roller adopts a semi spiral state and a few milling groove structures, effectively solving the problem of harvesting on rainy days and harvesting in the morning and evening. Harvesting can be done normally at noon.

In 2018, most of the machines will be updated as follows:

1. The original chain harrow bridge has been replaced with a more mature oneGreen storage machineThe pressure roller bridge completely eliminates the phenomenon of blade damage or direct damage to the blade disc of the grass cutter after the chain breaks. The pressure roller bridge allows for smoother and faster feeding of straw, and the grass cut from the crushed straw does not have a whole stem, with an average length of 1.5cm; Moderate length, stronger softness, more suitable for the taste of ruminant livestock such as cattle and sheep. This bridge has been declared for national use of the new ******.

2. The position of the crusher is directly connected to the bridge, making it more convenient to replace the blades. The connection distance is shorter.

3. The shredder blades are made of 18 straight pieces of 20 high-speed steel material, which is sharper and more wear-resistant. The cutterhead and knife holder adopt an eight shaped structure, and each moving knife must have strict tilt angle requirements; Make the knife sharper and more stable; Shorter shredding and less power consumption, saving a lot of horsepower for the engine.

4. Adding a secondary throwing fan makes the spraying distance farther, making the spraying operation more convenient and faster with the vehicle.

5. The front axle has been changed from the original wheat machine model with an open side reduction to a fully enclosed large side reduction, which will not cause the driving ring gear or gear breakage, or damage to the 209 bearing. It has stronger reliability, more stable and powerful driving performance.

6. Compared with last year, the rear steering axle has changed from a single steering hydraulic cylinder to a left and right bidirectional hydraulic cylinder, which has changed the phenomenon of the ground being too wet and the load being too heavy to move in the direction, or being too heavy. The left and right steering cylinders push and pull each other, making turning more flexible.

7. The rear tires have been changed from the original 10-15 wheat machine tires to 10/75-15.3 off-road tires, with widened and raised tires; More stable performance.

8. All vehicles are equipped with domestically high-quality Weichai 180 horsepower turbocharged National III high-pressure common rail engines. The engine is the heart organ of the entire vehicle, providing more powerful and stable performance.

9. The spray bucket adopts hydraulic 360 degree rotation, making your operation more convenient and practical.

10. All peeling machines adopt a fully adhesive flat roller structure, which provides more stable performance; The peeling rate is higher; The seed drop rate is lower, and all corn husks are ground after being crushed by a grinder. All bearings of the peeling machine are maintenance free bearings, which require no repair before oiling during use, eliminating the trouble of oiling.

11. The entire vehicle chain adopts the high-quality domestic enterprise Qingdao Zhenghe Chain, a Sino Japanese joint venture, which has a longer service life and more stable performance.

12. All the triangle belts of the whole vehicle are made of famous brand triangle belts produced by two companies, Zhongliang and Liannong. The material used is domestic GAO grade material, which has a longer service life and allows you to use it with confidence.

13. All deep groove bearings of this machine are purchased from the original factory as Halbin bearings, and all outer spherical bearings are Kaifeng Jingrun bearings, which can work for 300 hours without the need for oiling.

14. The ear picking and double disc cutting tables can be interchanged at any time. To interchange, only 16 screws need to be removed and a chain needs to be hung, instantly transforming into a true green storage machine.

15. The heat dissipation area of the water tank is greatly increased, and even if half of it is blocked by weeds, there will be no high temperature phenomenon.
