The invention discloses a horizontal-vertical conversion two-degrees-of-freedom portable forward mixing abrasive generation device which comprises an abrasive tank, a traveling platform and a right-opened L-shaped side frame; channeled rails are symmetrically arranged on the two sides of the abrasive tank through clamping rings; a mixing cavity base is arranged at the lower end of the abrasive tank; a reciprocating motion device A is arranged at the lower end of the mixing cavity base; arc-shaped bent plates are symmetrically welded at the bottom of the traveling platform; a swing adjustment plate is hinged to the top of the right-opened L-shaped side frame; and a reciprocating motion device B is arranged at the right end of the traveling platform. Degree-of-freedom reciprocating motion of the abrasive tank in the horizontal direction and along the abrasive tank in the direction perpendicular to the axial direction of a plane of an upper tank mouth in the abrasive tank can be ensured, the fluidizaton effect of an abrasive remained in the abrasive tank under the action of the gravity and water can be improved greatly, and the horizontal-vertical conversion two-degrees-of-freedom portable forward mixing abrasive generation device has the function of converting the abrasive tank between a horizontal type state and a vertical type state, and has the functions of micro leveling and partial folding.
