The present invention discloses a multifunctional micro-tillage machine which can be quickly disassembled. The power of its engine is output through the output shaft of the engine and drives the first transmission shaft to rotate through the bevel gear. The first transmission shaft drives the second transmission shaft and the third transmission shaft to rotate. When loosening the soil and tilling the land, the handrail is lifted up to make the machine head downward, and the rotary tilling head extends into the ground. At this time, the second transmission shaft rotates, and the middle section of the third transmission shaft idles. The walking wheels only support and stabilize the machine body. When it is necessary to move forward, the handrail is pressed down to suspend the rotary tilling head. At this time, the inclination measuring mechanism measures that the inclination is greater than the preset value and feeds back the signal to the controller. The controller controls the two electronically controlled clutches on the second transmission shaft to be disconnected, and the rotary tilling head stops rotating to ensure safety during the pushing process. At this time, the pushing can be controlled by the clutch. The two clutches of the third transmission shaft are connected so that the travel wheel obtains power and moves forward automatically. In addition, when the power is connected to the first transmission shaft, the transmission cylinder can be toggled through the toggle mechanism. The second and third bevel gears on the transmission cylinder can provide different steering directions when they are respectively engaged with the first bevel gear, thereby driving the travel wheel and the rotary tiller to reverse. The reversal can solve the problem of the rotary tiller getting stuck. In addition, the electronically controlled clutch can be used for reverse and forward rotation, such as the rotary tiller head rotating alone, the rotary tiller head and the travel wheel rotating together, the travel wheel rotating alone, the rotary tiller head and the travel wheel rotating on one side or both sides. When turning, the turning on the spot or U-turn can be achieved by controlling the unilateral rotation of the travel wheel, which greatly increases the flexibility of the micro-tillage machine and can adapt to various scenarios.
