Garbage compressor

The utility model relates to a garbage compressor. The garbage compressor comprises a box, a push head and a main hydraulic oil cylinder, a feeding door is arranged at the top of the box, a discharging door capable of vertically moving is arranged on the front portion of the box, the push head is arranged in the box, and the main hydraulic oil cylinder is connected with the push head. The garbage compressor is characterized in that the pushing plane of the push head does not seal a cross section corresponding to an inner cavity of the box, and a vertical clearance of 8-12 cm exists between the upper end edge of the push head and the upper end edge of the cross section. The garbage compressor has the advantages that manufactured garbage blocks are even in compactness and flat, and corners are not likely to loosen; meanwhile, the front end of the garbage compressor is good in rigidity, and the situation that a discharging door guide rail deforms due to large pushing force, and opening of the discharging door is hindered can be avoided.
