[0002] There are tens of millions of walking tractors with supporting power of 12-18 horsepower in my country. With the contracting of farmland, small-scale contractors generally contract farmland of about 100 mu, and most of the farmers are couples over 50 years old. Planting two crops a year, one hand-trailer has low labor efficiency and long cultivation time, and the purchase of two sets is short of manpower. Although the government subsidizes tens of thousands of dollars to buy a large tractor, it costs tens of thousands of dollars, and it is not worthwhile to use too much, because the supporting power is 12 -The rotary cultivator attached to the 18-horsepower walking tractor is powered by the gears in the chassis. Due to the limitation of the strength of the chassis transmission parts, the current walking tractor chassis can only be equipped with a rotary cultivator with a width of less than 1.2 meters. cultivator, so the operating efficiency cannot meet the actual needs of small-scale contractors

The invention discloses a high-power rear-mounted direct-driving rotary cultivator unit matching a hand tractor. The high-power rear-mounted direct-driving rotary cultivator unit comprises the hand tractor and a rotary cultivator installed behind driving wheels. An engine pulley directly drives a belt plate of the rotary cultivator and a tractor clutch plate through a belt. The operation breadth of the rotary cultivator ranges from 1.8 to 2.3 meters. Power of an engine ranges from 35 to 40 horsepower. The four driving wheels are respectively installed on a left driving shaft and a right driving shaft. A gearbox is arranged on the rotary cultivator. A driving shaft in the gearbox transmits power to a driving part in a side driving box such that knife roll shafts rotate. A press wheel is arranged behind the knife roll shafts. A tail wheel is arranged behind the press wheel. Through a hydraulic oil cylinder, the tail wheel ascends and descends. The high-power rear-mounted direct-driving rotary cultivator unit is based on an existing hand tractor so that investment is saved, purposes of efficiency and energy conservation are fulfilled and the needs of more contactors are met.
