Description

Pushing head mechanism, garbage compressor and garbage compression method Technical Field The invention relates to the technical field of garbage compression, in particular to a push head mechanism, a garbage compressor and a garbage compression method. Background The problem of gate slag inclusion is always an inherent pain point of the horizontal garbage compression process, and the problem is that the process needs to arrange a small openable gate, also called a gate, at the back of the box body, lift the gate up when garbage needs to be compressed into the box body, and put down the gate after the garbage is filled, however, in the process of falling down the gate after the box body is fully filled, the compressed garbage at the front of the box body can rebound or roll under the action of gravity, the garbage rolls down the gate, and the garbage can be clamped between the gate and the box body when the gate falls down. The problem of garbage entrainment not only causes the workload increase of operators of the transfer station, but also causes the penalty of management departments on operation units due to garbage splashing and sewage dripping and leaking during driving. The prior art solves the problem of slag inclusion of the gate by adopting the related technology of the transposition gate. The transposition door can be combined with the rubbish compressor push head to form a composite push head, when an empty rubbish transfer box is well docked with the rubbish compressor, the push head of the rubbish compressor is pushed out under the condition of no load (no rubbish), the push head is docked with the transposition door at the tail of the box to form the composite push head, the composite push head subsequently compresses rubbish into the box, and after the box is fully compressed, the push head is undocked with the transposition door, and the push head is left at the tail of the box.
