How to choose a combine harvester
The spring is warm and the peasants' friends are preparing for the busy season. Many of them have seen the considerable economic benefits brought by the cross-regional operations of the rice-wheat combine harvester. They are raising funds and they are asking about the appropriate prices and quality. Service machinery in place. (China-made farm machinery 503 rice harvester) We also received calls from many farmers asking about the performance and price of combine harvesters on the market. Here, provide some information for farmers' reference. In general, the purchase of combine harvesters depends on factors such as household economic status, presence or absence of large and medium-sized tractors, whether they are prepared to participate in trans-regional operations, and how long it is planned to recover investment. . 1. If you have a 50 hp tractor at home (such as Shanghai 50), you can purchase a backpack-type combine harvester that is compatible with the tractor. Currently on the market with good quality are "Guilin 6" (heading hydraulic lift) and "Five Mountain", "Xiang Ming" and other brands, unit price of about 25,000. In the past, there were backpack-type harvesters matched with 30 horsepower tractors. Practice has proved that the lack of supporting power affects harvesting results and is not welcomed by users. In recent years, it has gradually faded out of the market. Therefore, it is recommended that peasant friends do not save money to purchase a harvester with a matching power of 30 hp or less. The advantage of the knapsack harvester is that in the non-harvesting season, the tractor can be equipped with ploughs, rakes, and trailers for farmland cultivation, arranging, and transport operations. The harvesting time for wheat and rice is more than 20 days per year, and the net income is about 15,000 yuan. The harvesting and cutting machine investment can be collected in 2 years. The disadvantages are: Compared with self-propelled harvesters, the total loss rate and the impurity rate of piggyback machines are high, and the price and popularity of cross-region operations are not as high as those of self-propelled harvesters, nor are they suitable for wet soils. Harvest of rice. 2. Self-propelled full-feeding rice-wheat combine harvesters are divided into two types: wheeled and tracked. Among them, the wheel harvester is the oldest in the sales market and cross-region operations, with a holding of more than 80%. The main models are the "Xinjiang No. 2" and "Futian Gushen" series products, and the unit price is about 70,000 yuan. The main advantages of the wheeled machine are comfortable driving and flexible operation. The total loss rate, impurity rate, and breakage rate are all less than 2%. During the harvest season, the manufacturers are available 24 hours a day and four days, and the advantages of cross-region operations are obvious. Under normal circumstances, annual net income is about 30,000 yuan, and investment can be recovered in 2-3 years. What's not enough is that it is not suitable for harvesting rice in wet and dry fields; it has a high center of gravity and is not suitable for operation in mountainous hills. Another self-propelled full-feed harvester is a crawler type. The main models are the "Taizhou Liulin", "Whole Wave Pearl River" and "China Agricultural Machinery Bilang" series, the power is divided into several types of 45, 50 horsepower, the unit price is 40,000, 45,000 or so. The main advantage of this model is that it is suitable for rice harvesting in wet soil, and it has gradually become the preferred model for southern rice production areas. However, the cross-regional machine needs to be transferred by vehicles. The annual net income of the model is about 20,000 yuan, and the investment can be recovered within 3 years. 3. Tracked semi-feeding rice combine harvester has the highest technological content, highest price, lowest total loss rate and impurity rate (less than 1.5%), and of course the highest operating price (50 yuan/mu). model. The main feature of this machine is to separate the spikes from the straw, and the spikes enter the threshing device. After the straw is cut off, it is completely laid on the field and can also be chopped and returned to the field. The main models are foreign-owned enterprises or Sino-foreign joint venture production of "Kubota", "Toyo", "Yanma - People's number" and several other major components are provided by Japan, the unit price of 200,000 yuan. Most of these machines are currently concentrated in rice production areas in developed regions such as Jiangsu and Zhejiang. The domestically produced half-feed harvesters have brands such as "agricultural machinery" and "Futian". The engines are imported direct-injection engines with a power of 45-53 hp. The use of continuously variable speeds, automatic feed depth adjustment, and hydraulic cutting heads Lifting and steering, rapid secondary threshing and secondary cleaning, efficient straw cutting and other advanced technologies. The disadvantage is that the stand-alone price is about 160,000 yuan, and the investment recovery period is more than 5 years. Cross-regional operations require special vehicles for transportation. 4. The harvester must also pay attention to the “three guarantees†service promised by the manufacturer, especially whether the service measures during the busy season are reliable and whether there are nearest retail outlets for repairs and wearing parts. 5, after the purchase of the first to participate in the technical training organized by the factory or agricultural machinery department, master the basic operation and maintenance, maintenance and common sense before boarding. Operators who are prepared to participate in cross-region operations shall promptly contact the agricultural machinery management department, receive the cross-district operation certificate jointly issued by the agriculture, public security, and transportation departments, and participate in the cross-regional operation team organized by the agricultural machinery department, organized, with purpose, and Plan to go out.
