Comparison of technical performance between semi-feed and full-feed harvesters

Technical performance comparison of semi-feeding and full-feeding harvesters:

1. The semi-feeding harvester is more complicated than the full-feeding harvester. Once the fault occurs, it is difficult to eliminate the repair, the parts are expensive, and the disassembly and repair is difficult. The full-feeding harvester has a simple structure, many parts can be seen and touched, faults are easy to repair and remove, suitable for farmers' hands, and repair costs are low. Farmers are willing to use full-feed harvesters.

2. Analysis of economic benefits, such as a Yanmar Ce_2M type semi-feeding and a Zhejiang Sanlian 4LZ_1.8 full-feed harvester comparison acceptance, the same piece of rice field, unified time, each machine harvesting 2 acres area, Yanmar machine After 18 minutes and 42 seconds of harvesting, Zhejiang Sanlian 19 minutes and 31 seconds have also been harvested. The difference between the three online and the Yanmar machine is 40 seconds, which may be related to the technical proficiency of the operator. The total loss rate of the triple harvester is less than 3.5%, and the total loss rate of the Yanmar harvester is often more than 3.5%, because the machine uses the chain transmission to deliver the rice device, and the loss rate occurs under the force of the mechanical transmission chain. Larger. Therefore, farmers have different views on the semi-feeding harvesters. The whole feed is fed into the harvester. When the harvesting speed is combined with the reeling wheel, the rice is transferred into the augmentation tank to ensure that the grain of the rice is returned and the loss is small.

3. Some farmers in the south still have cattle. Therefore, when harvesting the harvester, the rice straw is not rolled by the thresher. The rice straw is hard and the old leaves are muddy. The farmer does not like to eat. Farmers are not willing to ask for semi-feeding harvesters in the evening, and all-feeding harvesters are suitable for both early and late harvesting.

4. Comparative analysis of purchase price, a Yanmar Ce_2M harvester, the price of each unit more than 210,000 yuan, a Zhejiang Sanlian 4LZ_1.8 full feed harvester price of 49,500 yuan. The peasants think that if you buy a horse, you can buy 4 sets of Zhejiang Sanlian. If our farmers don't have so much money to buy Yanmar machines, they will buy them all into the harvester!

5. Analysis of faults, semi-feeding into the Yanmar harvester, there are not many faults in using 1-2 years, the faults in the third year are very obvious, sometimes one or more faults occur one day, the repair and spare parts of the machine The fee is very expensive, the farmers can't afford to buy it, so they are not willing to use this machine. While Zhejiang Sanlian is fully fed into the harvester, although there are many faults, but the advantages of cheap spare parts and less repairs, farmers like to use all-fed agricultural harvesting machinery, which is one of the ideal machines.
