The invention provides a self-propelled miniature underground pipeline boring machine, the cutter head mechanism adopts blade radial position and cutting angle adjustable design, the blades will be set to the spirals, reduce the edge of each blade size, reduce the power requirements; and the realization of each adjustable holder and fixed knife force equal, the overall force balance, providing the forward thrust axis when cutting, is conducive to the cutter head along the axial direction forward; in addition, according to the characteristics of different soil adjusting the blade cutting angle, cutting speed, reduce tool wear, to ensure the liquidity of cutting soil, improve the service life of the cutter head. The walking mechanism is provided in the chain chain tensioning mechanism tension; by moving parallel adjusting mechanism to achieve the parallel support, with two parallel the distance between brackets automatically adjusted according to the degree of soil porosity and soil function, ensure that the chain can always contact with accessories; through the chain and the chain motion effectively when soil contact, produce enough thrust forward.
