Grain combine is called combine harvester for short. It is a combine for harvesting crops. It was called Combein in the early 1950s. Harvesting machinery for direct harvest of grain in the field.
From the 18th to the 19th century, many people in Britain, the United States and other countries developed and designed combine harvesters. Some of them also obtained patents or made prototypes, but they basically had no practical value and could not be promoted.
In 1831, the American peasant inventor C. McCormik (1810-?) Designed and produced the first combine harvester towed by two horses. The harvesting efficiency was more than 30 manual workers. This is a combine harvester A major breakthrough in development. Since then, McCormick has been committed to the improvement and manufacture of combine harvesters, and his combined harvesters have been in short supply. By 1870, the large combine he manufactured was towed by 40 horses, and the width of the harvest was 30 meters. The harvester was also equipped with a bale packing device.
In 1889, Americans

The domestic harvester started late. In the early days, it was mainly imitated and imported from the Soviet Union, the United States, and Canada. Many connection or support parts have not been calculated in detail, but are designed and manufactured according to the size of harvesters already made in developed countries, making the harvesters bulky and of high quality.
Large harvesters are very complex machinery. The use of large harvesters has higher requirements for land leveling and scale.
The grain combine harvester is mainly used for combined harvesting of wheat crops, and can complete cutting, threshing, separation and cleaning operations in the field at one time. When used for segmented harvesting, a harvester is installed on the harvesting table to pick up the dried cereal strips and complete the operations of threshing, separation and cleaning. Grain crops such as rice, corn, soybeans, millet, and elevated cereals can be harvested when auxiliary equipment (such as soybean low-cut equipment, etc.) are added to the grain combine, or after appropriate modification and adjustment [2]

Agricultural machinery as a good helper for agricultural production and prosperity,
Not only must you buy and maintain it properly, but it is also very important to properly operate, use, maintain and maintain the machine.

Careful operation is an important link to improve the efficiency of rice combine harvesters. The majority of agricultural machinery operators at Heilongjiang Nongken 589 farms, when driving rice combine harvesters, paid particular attention to the following two points and achieved good results. Now they are introduced as follows:
Combine driving straight
During the operation of the harvester, the operator of the agricultural machine should operate the harvester in a straight line operation. In this way, one can improve the operation efficiency and the other can reduce the waste of rice in the harvester operation.
Combine harvester forward speed
According to the growth of the rice, the yield, the degree of dryness and wetness, and the dryness of the rice field, the forward speed of the harvester operation is controlled to make the harvester work at full capacity as much as possible to improve the efficiency of the operation. If the rice grows well and the yield is high, the harvester operation speed can be slower. If the paddy field is dry, the harvesting speed can be faster [3] .
