1. Work flow comparison

Traditional corn harvesters are mostly self-propelled ear-picking machines, and they are also the main force of the current corn machine. In use, the corn is first picked and peeled, and then the corn is pulled back by the transport truck for air-drying. After air-dried, it is threshed and threshed. Dry the grains before they can be stored and sold. There are many working procedures, many labors, large space occupation, high cost, and also affected by the weather and site. Basically, different degrees of losses are caused every year.

During the operation of the grain-type corn harvester, the operations of picking ears, peeling, threshing, Qingyuan, and straw crushing of corn are completed at one time, eliminating the need for the secondary transportation and secondary drying of the ears of corn in the ear picking corn machine. , Improve work efficiency, reduce the number of labor, reduce costs, reduce costs, and it is more in line with the development direction of corn mechanization.

2. Comparison of comprehensive operating costs

After the ear-picking type corn harvester operates, the ears of corn are transported to the designated place for drying and threshing. The cost of secondary transportation and threshing is about 30 yuan/mu. After the grain-type corn harvester is in operation, the corn kernels can be directly transported to the designated drying place for drying. The transportation cost is about 10 yuan/mu. And because the grain-type corn harvester has a small moisture content, it is easy to Drying and drying costs are also low, about 20 yuan per acre can be saved.

3. Comparison of operating efficiency

For a plot of the same size, since the volume of corn ears is much larger than corn kernels, the number of unloading grains and the frequency of transporting corn ears during the operation of the ear-picking corn harvester are much more than that of the kernel corn harvester. Approximately the ear-picking-type corn harvester unloads the grain 4 times, and the grain-type corn harvester unloads the grain once. The increase in the number of unloading grains will inevitably affect the operating efficiency of the ear-picking-type corn harvester, so the grain-type corn harvester The operation efficiency is higher, and the increase in transportation times will make the soil more compact, which is not good for the soil itself and subsequent operations.

4. Comparison of losses in operations

The ear-picking corn harvester needs to go through the links of ear picking, peeling, transportation, drying, threshing, re-airing or drying, re-transporting, storage, and sales. Generally speaking, the more links, the more losses. Each link may cause loss, and the total loss will be more. The grain-type corn harvester is harvested into kernels when used, and then pulled off for drying, dried, stored and sold.Compared with the ear-picking-type harvester, the operation link is much less, which minimizes the possibility of food loss. The loss will be much less.

5. Comparison of grain production increase during operation

The grain-type corn harvester has high requirements for the moisture content of corn when it is used. Generally, the moisture content of the corn is required to not exceed 24%. For the ear-picking corn harvester, the moisture content of the corn during harvesting is much lower. Even if the water content of the corn kernel exceeds 36%, the ear picking operation can still be carried out normally, so when the kernel type corn harvester is operating, the harvest period is relatively late, generally about 15 days later than the ear picking type harvester. The late harvest of corn helps to further increase the yield of corn per mu and the quality of corn. Therefore, when the corn kernel harvester is used, the yield of corn is higher, the quality is better, the price is higher, and the income of the corresponding farmers is also higher. .

Through the above analysis, it can be seen that the use of corn kernel harvester for corn harvesting operations has the following advantages: low operating cost, high efficiency, small loss, and farmers' income.
