Disclosed is a wheel-track adjustable and self-propelled chassis for a mortar device, which includes a frame (10), a frame crosstie (1) and a wheel set. The wheel set includes more than one wheel frame (9) and wheels (11) fixed on the wheel frames (9). The wheel frame (9) is fixed on a longitudinal girder which is fixed at the frame crosstie (1) through a hinge frame (2). Along the distribution direction of the frame crosstie (1), more than two sets of mounting holes (12) are provided on the frame crosstie (1) in turn. The hinge frame (2) is connected with the frame crosstie (1) by a connecting component provided in and penetrating through either set of mounting holes (12). A mortar vehicle is also disclosed, which includes the self-propelled chassis described above and a mortar fixture (13) equipped on the self-propelled chassis. The self-propelled chassis has advantages of simple and impact structure, low cost, easy installation, convenient operation and large accommodation.
