The Milling Machine was originally a horizontal milling machine created by American E. Whitney in 1818.In order to mill the spiral groove of the twist drill, American J.R. Brown created the first universal milling machine in 1862, which is the prototype of the milling machine for the lifting platform.The portal milling machine appeared around 1884.Semi-automatic milling machines appeared in the 1920s, and the workbench used the stops to perform automatic conversion of [feed-fast" or [fast-feed".After 1950, milling machines developed rapidly in control systems, and the application of digital control greatly improved the automation of milling machines.Especially after the 1970s, the digital control system and automatic tool change system of the microprocessor were applied on the milling machine, which expanded the processing range of the milling machine and improved the machining accuracy and efficiency.As the mechanization process intensified, CNC programming began to be widely used in machine tool operations, which greatly released the labor force.CNC programming milling machines will gradually replace manual operations.The requirements for employees will also be higher and higher, and of course the efficiency will be higher and higher.

The 4QZ-5.0 self-propelled silage harvester has reasonable structure, strong power, simple operation, convenient maintenance and reliable performance. It is suitable for harvesting, chopping and loading of corn, sorghum, sorghum and other high-crop crops. In order to facilitate the operation during harvesting, the machine is equipped with a discharge port that can adjust the direction of any hydraulic pressure, and adjust the direction at any time to make the chopped crops spray smoothly onto the receiving car. According to the height of the crop, the height of the reel can be adjusted up and down according to the height of the crop, and adjusted to a suitable position for harvesting. At the same time, according to the cutting height required by the user and the terrain leveling, the hydraulic cylinder can adjust the cutting knife up and down to the appropriate position. The harvesting mechanism, conveying mechanism, chopping mechanism, spraying mechanism and other mechanisms have been adjusted and fixed before leaving the factory, and can be used without user adjustment.
The machine uses special steel as the material for manufacturing shredder blades, which is more durable and durable. The continuous working time reaches a harvesting season, which greatly improves the overall utilization rate. The machine belongs to the non-lineage harvesting. Like the wheat harvester, it is not restricted by the line spacing and cutting width within the harvesting range, and can be opened by itself and enters the harvesting area. When the harvesting amount is too large, the machine is safe. The clutch and the retracting device can operate the forward and reverse clutch handles at any time when there is excessive feeding, causing the crop to be vomited and instantaneously entering the normal harvesting.
The main technical specifications of 4QZ-5.0 self-propelled silage harvester: the length of the feed section is 15 to 40 mm, the supporting power of the machine is 136 horsepower diesel engine, the whole machine is 6.8 meters long, 2.3 meters wide and 3.8 meters high. 5.8 tons. Its harvesting platform is 2.6 meters wide and can harvest green crops within 4 rows at the same time. Harvesting efficiency can reach 30 to 50 tons in pure working hours. The harvested crops have a height of 0.6 to 4 meters and a stubble height of 0.05 to 0.1 meters, which does not affect the cultivation of the lower crops. For the chopping effect, the user can rest assured that the machine is rolled and cut after 7 rolling. The chopped straw is not only short but also flocculent, and can be directly sealed and stored after harvesting without adding any additives. It can become a favorite food for cattle and sheep.
Self-propelled silage harvester
With the development of China's agricultural economy, artificial labor has seriously hindered the development of efficient agriculture in China. In order to adapt to the development and requirements of China's agricultural animal husbandry, the 4QZ-5.0 self-propelled silage harvester developed by Beijing Dele Machinery Factory provides favorable conditions for agricultural aquaculture in China.
