The corn combine harvester is at the heart of the mechanization of corn harvest. Correct purchase will bring more obvious economic benefits to farmers. So, what is the correct purchase of corn combine harvesters? First, pay attention to the adaptability of the machine. At present, China's corn planting area is about 24 million hectares, and has formed three major production areas, namely the northern corn area, which includes the provinces of Liao, Kyrgyzstan, Heihe and Lisu, and the sown area accounts for 40%; the spring and summer corn area of ​​Huanghuai Plain , Including the provinces of Lu, Yu and Su, the sown area accounts for 25%; southwestern hilly corn areas, including clouds, and other provinces, the sown area accounts for 15%. Due to a wide range of planting, different crop varieties and climatic conditions, and differences in agronomic practices, the corn stalks and grain moisture at harvest differ significantly. The corn combine harvester produced in China is based on certain agronomic farming patterns (such as row spacing and plant spacing) and has obvious regional characteristics. Therefore, pay special attention to this when purchasing corn combine harvesters, organically combine the regionality of the implements with local agronomic practices, and use the advanced and adaptable corn harvester The preferred model. Because you can't adapt to different lines, you don't need to manually help cut the road. Can work from different locations in the field, the work efficiency is high. Second, we must pay attention to the issue of investment efficiency. The corn combine harvesters currently produced in China are self-propelled, suspended (front suspension and side suspension), and traction; the number of rows is: single and multiple rows. Self-propelled multi-line, large models, and expensive. The general price is 3 lines: 10-13 million yuan; 4 lines: 180,000-200,000 yuan, the investment recovery period is longer; the length of the tractor-type aircraft unit is not suitable for small plots; and manual harvesting and artificial harvesting are also needed. In addition, the backpack has some difficulties in structural arrangement. When the front suspension is used, the driver is not easy to see the header. In general, there is no power output shaft at the front of the tractor. The tilt angle of the transport box is not more than 17o, and the front end mass distribution is too heavy. However, it is short of fuselage, flexible operation, good maneuverability, and strong operability, plus no need to open the road artificially, which is suitable for the current status of small rural planting plots in China; second is to make full use of existing tractors, one-time investment relative Less, generally single behavior: 0.85 - 10,000 yuan; 2 lines: 2.5 - 30,000 yuan, a short payback period, suitable for the current low level of rural economic characteristics; Third, the operating efficiency is also better. Therefore, piggyback should be the current preferred model. Third, we must consider the power of the match. At present, the general power of tractors combined with corn combine harvesters is above 50 horsepower. Therefore, when choosing a corn harvester, farmers' friends must choose the model that matches their existing tractor power. For example, a 50-horsepower tractor can be matched with two rows of corn harvesters, such as Shandong Yufeng and Guofeng, while farmers with 55, 600, 654, 700, 724 and other types of tractors can choose Tianjin Fukang and Hebei Nonghaha. Line model or other 3 row corn combine harvester. In order to avoid the phenomenon of “small horse-drawn carts†or “big horse-drawn cartsâ€, the best combination of tractors and harvesters can be achieved. Fourth, we must fully consider the quality of products and after-sales service. From the aspect of product quality and performance, we should choose the famous and high-quality products with mature technology, product molding and national recommendation. Such as Tianjin Fukang, Hebei Nhaha, Shijiazhuang Bugu, Shandong Yuzhou, Yufeng, Guofeng and so on. On the price, the preferred cheap. Second, we must choose a strong after-sales service, spare parts supply timely manufacturers. At the time of purchase, it depends on whether the three certificates (product certificate, warranty certificate, instruction manual) are complete. Finally, do not forget to request a purchase invoice.
