A tile removing device according to the present invention comprises: a cam unit (30) for assembling multiple cams (31) in a cam axis (32) at regular intervals inside a housing (10), which includes a pair of handles (20) and multiple wheels (11), and for rotating the cams along with the axis; a knife unit (40) comprising a rod (42) where a guide roll (41) is formed and a spring (42) is installed, a rod (45) where a knife (46) is assembled at the end unit and which is supported by a guide (61), a universal joint (44) connecting the rods (42, 45), and a guide body (47) supporting the rod (42) and playing a role as a guide; and a geared motor (50), which includes a belt (or a chain) (33) for rotating the cam axis (32). The rods (42), which are of the same number of the cams (31), are installed. When the cams rotate according to the rotation of the cam axis, the top dead center of the cams hits and pushes the guide roll (41). At the same time, the rods (42, 45) perform a straight-line motion and the knife (46) assembled at the end unit hits a tile on the floor. It is desirable that the multiple cams (31) installed in the cam axis (32) adjust the positions of the top dead center to be located at the same interval and hit the guide rolls (41) in a sequential order. |
