　　Qingdao combine small make up to tell you how to introduce agricultural machinery accessories

　　The origin of the agricultural machinery use simple tools can be traced back to primitive society era. In China, the neolithic yangshao culture period (about 5000 ~ 3000 BC) had the original tool of cultivated land ─ ─ LeiSi. In the 13th century BC used copper oxen-led ploughshares. To the third century BC during the spring and autumn warring states period, has cultivated land, sowing, harvesting, processing and irrigation, and a series of iron, wooden farm tools. Around 90 BC, invented by three lines of zhao Lou, namely three line drill, its basic structure is still being used. To the 9th century structure has been formed a complete animal furrow to plough. In qimin yaoshu (about 540), "LeiSi classics" (880), acla) "agricultural book" (1310), "characterized by open objects" (1637), and other ancient books, for various periods of agricultural production have all sorts of machinery and tools used in the detail records. In the west, the original lumbering originated in Mesopotamia and Egypt, about 1000 BC iron plowshare came into use.

　　In the 19th century to the beginning of the 20th century, is the development and extensive use of new animal s agricultural machinery. In 1831, the United States, C.H. McCormick created mara harvester to success. In 1836 the first horse grain combine. From 1850 to 1855, successively manufactured and promote the use of the grain drill, lawn mower and corn seeder, etc. The beginning of the 20th century, powered by internal combustion engine of the tractor to start gradually instead of cattle, as traction is widely used in the field, and used to drive various fixed operation of agricultural machinery.

　　In the late 1930 s, the British H.G. ferguson farm tools to create successful tractor suspension system, make tractor and farm implements both form a whole, greatly improving the use of tractors and operating performance. By hydraulic control tools suspension system also make tools more lightweight, flexible manipulation and control. Agricultural machinery with tractor kit by towed toward hanging and half hanging, agricultural machinery and reduction in weight and simple structure. The 40 s, Europe and the United States grain combine gradually from the towed to self propelled. In the 60 s, fruits, vegetables, such as mechanical harvest. Since the 70 s, the electronic technology gradually applied in the agricultural machinery operation monitoring and control of the process, gradually to develop in the direction of process automation.

　　The early founding of the Peoples Republic of China, widely develop new animal farm tools, such as walking plough, hoe, planter, harvester and water wheel, etc. Late 50 s, China began to build tractors and agricultural machinery manufacturing industry. The first tractor factory in luoyang were completed and put into operation in 1959. In 1972 created a successful ship tractor (cultivating boat), for paddy field in southern China, especially the perennial water retting traction field region offers a variety of purposes. By the end of 1984, the country (except Taiwan province), large and medium-sized tractor ownership of 854000 units, small and walking tractor to 3.298 million, 350000 cars in agricultural use, agricultural drainage and irrigation machinery of 6.15 million units, agricultural water pump of 5.157 million units, large and medium-sized tractor supporting machinery reached 1.235 million units, small and walking tractor supporting machinery reached 2.918 million units, corn united harvest machine 35861 units, feed mill of 1.139 million units, the grinding machine, rice mill, cotton gin and oil press, a total of 3.881 million units, agricultural total of 1.95 x 10 kw power. In 1984, mechanical ploughing area of 524 million mu, accounting for 39% of the cultivated land area. Electromechanical irrigation area of 376 million mu, accounting for 56.4% of the irrigation area.
