Corn harvesting: the best harvest corn harvester is the best choice

[ China Agricultural Machinery Industry News ] By 2013, China's corn mechanized harvesting level is only 49%, and the level of direct degranulation is lower. Therefore, in order to solve this problem in China, further research on corn grain direct mechanization is needed. The picking corn harvester is only a “semi-finished product” in the historical process. Looking at the world, agricultural developed countries suitable for corn growth have already achieved large-scale corn grain direct harvest, which not only reduces manual labor expenditure, but also shortens operation time and high yield.
I have to admit that the existing corn planting model in some agricultural developed countries is the object of our study, especially the agricultural equipment in the corn industry chain is the direction of China's agricultural machinery industry. From the development history of corn harvesters in agricultural developed countries, it can be seen that the picking corn harvester is a “transition product” in the corn harvesting stage, and the grain direct harvesting corn harvester is a good model for corn harvesting.
Corn harvesting: the grain harvesting corn harvester is the best choice
The time is ripe for the widespread use of grain harvest corn harvesters. As the saying goes, you can't eat a fat man. The mechanization of the corn harvesting process also needs to be step by step. Most of China's corn-producing areas have explored new corn varieties adapted to the local climate and took a step toward direct corn harvesting. Many corn harvesting machine manufacturers in China have also developed and promoted the grain harvesting corn harvester, which has made the "machine" available, and took the second step to the corn grain. The existing new corn varieties suitable for direct grain harvesting must be dried as soon as possible after the corn kernels are directly collected, otherwise they will be mildewed and become garbage waste without any use. In recent years, all parts of China have been increasing subsidies for grain dryers. The annual sales volume of grain dryers is increasing, and the number of possessions is rising. It is understood that the voices of subsidies for grain drying operations are also rising. As this develops, farmers will have dryers available, and they will also be able to use them, which is equivalent to taking the third step directly to corn grain.
In the non-plain area, the small corn harvester will be the next “wind vent”
China's territory is vast, and its landforms and climate characteristics are very different. From the perspective of agricultural planting, the flat area of ​​farmland is suitable for large-scale planting. Although hills, mountainous areas and other plots are not suitable for large-scale agricultural machinery scale operations, industrious Chinese farmers have changed these places into “landscapes” with rich regional characteristics. Although these farmland can be contiguous, but because the ground is uneven, they are sorted into "small and long" fields, and the machine farms don't even have to think about it. Therefore, these plots can only use small agricultural machinery.
The total area of ​​hilly and mountainous areas in China is not small. For a long time, it has been mainly based on manpower and animal power. These places have been upgraded to “machine-for-bomb” and “machine-for-man”. The total amount of agricultural machinery to be used is also a huge number. . Although these places are not a dominant area for corn cultivation, China is a country with a long history of cuisine. There are many different kinds of meals in various places, so the total area of ​​corn planted in these places is also considerable.
After the baptism of the “golden development period” of the agricultural machinery industry in previous years, most of the plain areas in China suitable for large-scale corn planting, the corn harvester possession has reached a historical high, and many places have reached saturation. However, the above-mentioned hills, mountains and other non-plain areas that are not suitable for large-scale corn planting, the corn harvester possession is very low, but the total demand is obvious. At the same time, small corn harvesters suitable for operation in these places are developing at a slower speed. Although some manufacturers are developing, they are unable to meet the demand due to the low profit margin, limited R&D investment and few suitable models. .
"Corn harvest + straw baling" one machine will be the next "wind vent"
In recent years, China's agricultural machinery purchase subsidy policy emphasizes green environmental protection as a guide, so grain dryers, subsoilers, straw crushing and returning machines and straw balers, etc., which are characterized by green environmental protection, will become The “wind vent” of the entire agricultural machinery industry, production and sales have been climbing, and the heat is not reduced. In the first half of 2017, the popularity of these popular agricultural products far exceeded the “four major pieces” of agricultural machinery in the traditional sense. The brilliance of tractors, wheat harvest, rice harvest and corn harvest can be said to have been completely covered by these popular agricultural machinery.
Considering the cost of operation time, fuel consumption, labor, etc., the “harvest + straw baling” machine can save a considerable amount of manpower, material resources and financial resources by saving one operation. From the machine structure, according to the author's understanding, there have been domestic production companies have developed a "green feed harvest + baling" one machine, and some products have obtained the ministerial agricultural machinery promotion identification certificate, the application of this design to the wheat harvest, Corn harvesting should not be difficult.

Aluminium Castings, processing ways mainly include Sand Castings, Low Pressure Castings, and die castings / High Pressure Castings

Examples of items mainly are aluminium housing, pump gear box, pump housing, valve body, marine parts, Auto Parts , and turbocharger compressor wheel, bearing housing and compressor housing etc.. 

Die casting is the most important processing way for aluminium castings. 


Advantages of die casting:

  • Excellent dimensional accuracy (depend on casting material, but typically 0.1 mm for the first 2.5 cm and 0.02 mm for each additional centimeter.
  • Smooth cast surfaces.
  • Thinner walls can be cast as compared to sand and permanent mold casting.
  • Inserts can be cast-in.
  • Reduces or eliminates secondary machining operations.
  • Rapid production rates.
  • Casting tensile strength as high as 415 megapascals (60 ksi).
  • Casting of low fluidity metals.
  • compressor housing
  • aluminium housing
