How are agricultural machinery classified?
As agricultural production involves a wide range of agricultural machinery, the operation of the object is also a lot of, so, the type of agricultural machinery is quite complex. The former National Machinery Industry Standard (NJ89-74) stipulated the classification and number of agricultural machinery according to its use and agricultural production process, and required that the newly designed models must be named and numbered according to this standard. According to its requirements, agricultural machinery is divided into nine categories, as shown in the following table.
Classification table of agricultural machinery Classification no：
1. tilling machinery such as: 1L - plow, 1B - rake, 1P - grader
2. planting and fertilizing machinery for example: 2B - seeder, 2F - fertilizer machine
3. Field pipe plant protection machinery such as: 3Z - cultivator, 3W - spray machine
4. Harvesting machinery for example: 4Y - corn harvester, 4G - harvester
5. Threshing, cleaning and drying machinery such as: 5X - cleaning machine, 5H - dryer, 5T - threshing machine
6. agricultural and sideline products processing machinery such as: 6N - rice milling machine, 6Y - oil press
7. Loading and unloading and transportation machinery, such as: 7G - trailer, 7Y - agricultural transport vehicle
8. drainage and irrigation machinery such as: 8J - drilling machine, 8C - water wheel
9. Animal husbandry machinery such as: 9Y - baling machine, 9G - lawn mower, 9F - grinder
Other machines that do not fall within the scope of the above mentioned machinery shall be classified as "0", but 0 shall not be written in the numbering. For example, L-3.6 indicates a connector with a width of 3.6 m.
The model of agricultural machinery and tools consists of three parts: category number - group number - characteristic code - specification - replacement mark. The category number of agricultural machinery and tools is the above-mentioned classification number, represented by Arabic numerals.
Agricultural machinery and tools group number to represent the use of agricultural tools (such as plows, harrows, sowing, etc.) the first letter of the Chinese pinyin. The characteristic code of agricultural machinery and tools is represented by the first letter of the Chinese pinyin of the main characteristics of agricultural tools (structure, dynamic form, etc.). Sometimes it is also represented by the representative letter in its Chinese pinyin characters. The specifications of agricultural machinery and tools are determined randomly with working characteristics, such as the number of plow body × single share width; Rake width; The number of seeding rows for the seeder; Combine harvesters are measured in kilograms per second.
