Description

Hopper with uniform blanking

Technical Field

The invention relates to the technical field of feeding devices, in particular to a hopper with uniform blanking.

Background

The garbage incinerator is equipment for incinerating household garbage. When garbage is put into the hopper of the garbage incinerator, the garbage is generally grabbed from the garbage bin by the grab bucket and then conveyed to the center of the hopper opening to be released in the prior art, so that the garbage incinerator is charged.

In order to ensure that the waste falls entirely into the hopper, the grab must be smaller in size than the mouth of the hopper so that most of the waste is deposited in a central location when it falls through the hopper onto the pusher, with only a small portion falling on either side of the pusher. When the garbage is conveyed to the fire grate, too much garbage is accumulated in the middle, the garbage on two sides is too little, so that the garbage incineration efficiency is reduced, even the phenomenon of insufficient combustion possibly occurs, particularly, a large number of cloth steel wires and other objects appear in the garbage, the garbage can be bundled into a group to be subjected to the phenomenon of lump combustion on the fire grate, the condition of insufficient combustion is easily caused, and the boiler incineration efficiency is reduced.
