Know the Combine Harvester

Combine harvester, or a combine harvester, is a combined machine for harvesting crops. In the early 1950s, it was called Combein. It was a process that can complete harvesting, threshing, separating stems, and removing debris from cereal crops. Harvesting machinery for harvesting grain directly from the field.

Before the combined harvesters were introduced, threshing machines and mechanical harvesting machines greatly increased agricultural productivity in the 19th century. This makes it possible to harvest more grains with fewer workers than before. However, an invention in the late 19th century further improved this efficiency. Combine harvesters combine the harvesting and thresher in one piece, allowing farmers to perform harvesting and threshing in a single operation.

The current situation of domestic harvesters

The domestic harvester started late, and early imitation was the mainstay. Many connecting or supporting parts have not been calculated in detail, but have been designed and manufactured according to the size of the harvesters that have been made in developed countries, making the harvester bulky and of high quality.

Large harvesters are very complex mechanical equipment. The use of large-scale harvesters imposes higher requirements on the leveling and scale of the land. The well-known wheat in the North China Plain and the Sanjiang Plain, etc., have long been used in the rice-growing areas for production.

Relative to large-scale harvesters, the design of small harvesters is more arbitrary. Many colleges and universities in China are now trying to design and manufacture miniature harvesters. These institutions design small harvesters suitable for the local land environment and productivity. Such harvesters are low in price, easy to maintain, easy to use, suitable for various terrains, and have low maintenance requirements. This type of harvester is generally purchased by individuals and is suitable for small-scale production of small farmers.

Use points

The length of service, the failure rate, and the safety and reliability of any machine are not only related to the quality of the machine itself, but also to the use and maintenance of the machine. The use of a combine harvester is no exception. The following points should be noted:

1. The machine operator must go through the formal training of the manufacturer, distributor or related department before taking up the job. If the working principle and operation requirements of the combine harvester are not clear, it is difficult to use a good combine harvester. Therefore, before the machine is used, it is necessary to participate in the operation training of the combine harvester and obtain a driver's license.

2. Please read the product specification carefully before use. Because the structure of the combine harvester is complicated, even though the machine quality is very good, if you do not understand the internal structure and the usage method, you can use it casually according to experience. If you do not operate in accordance with the specification, the machine is prone to untimely failures.

3, because the harvested crop conditions vary greatly (such as crop varieties, maturity, moisture content, yield, crop height and lodging situation, etc.), so in the use of combine harvester process, should be for changes in crop conditions Timely adjustment of the machine's various related agencies to ensure the performance of the combine harvester.

4. The safety protection device installed on the combine harvester is designed to protect the safety of the operator and its related personnel. Therefore, the machine cannot be disassembled when it is running or working. If it has been dismantled during maintenance, the machine must be restarted before operating or working. Install it. In addition, when operating the machine, it must be performed in accordance with the relevant safety warning signs to avoid accidents.

5. The combine harvester shall be inspected, maintained and maintained regularly and promptly. Such as checking whether there is lack of oil, lack of water, whether there is loosening, whether there is a place for welding, whether there is abnormal sound and so on. If there is any abnormality, it should be replenished, adjusted and repaired in time, and the machine must not be allowed to work sick. Otherwise, large failures or damages are likely to occur.

6. In most cases, the structure and overall parameters of the combine harvester are coordinated from the design and cannot be arbitrarily changed or modified. Such as increasing the engine speed, increasing the height of the grain tank, etc., this will not only guarantee the performance of the work, but also accelerate the wear and damage of the machine.
