Compared with the prior art, the hammer crusher has the advantages that the crusher is capable of effectively limiting splashing fragments and dust generated in crushing operation within the crusher without splashing to hurt people and dust pollution, and the crusher is safe and environment protective, and simple in structure, convenient in fabrication and low in fabrication cost.

Description

A kind of hammer mill

Technical field the utility model relates to a kind of crushing mechanism, the hammer mill that particularly a kind of mine, cement industry are used.

The background technology hammer mill is when crushed stone lime stone ore, coal cinder or shale, because the percussion of the quartering hammer of rotation, fine grained chippings that crushing operation produced and dust can outwards splash from charge door, near if the operating personnel is in, just may damage, and dust also can pollute environment personnel.At this problem, those skilled in the art also carried out some improvement, as adopt the wet type fragmentation or increase the mode that striker plate blocks, to splashing or dust prevention and control is all obtained certain effect, but existing controlling mode all exists some limitations and deficiency, better as the broken dust prevention and control effect of wet type, but can not control splashing.Chinese patent publication number CN2533948, open February 5 2003 date, invention and created name " hammer mill ", a kind of obstruct iron chains anti-splash hammer mill that adds is disclosed, though the broken splash of hammer mill is had must protective action, but protection effect is undesirable, and still has the problem of dust pollution.

The summary of the invention the purpose of this utility model is exactly at the deficiencies in the prior art, provides a kind of and can prevent effectively that fragment from splashing, and can prevent dust pollution again, and hammer mill simple in structure, easily manufactured, low cost of manufacture.

For achieving the above object, the utility model adopts following technical scheme:

A kind of hammer mill comprises casing, rotor, bearing block, charge door, discharging opening, stop gauge, and described stop gauge is made up of outer striker plate and interior material blocking shade; Outer striker plate is arranged on the charge door front end, and the vertical section of the outline of outer striker plate and charge door front end adapts, and outer striker plate is movably connected in the top of charge door by the upper end; Interior material blocking shade is arranged on the charge door rear, and the vertical section of the outline of interior material blocking shade and charge door rear end adapts, and interior material blocking shade is movably connected in the upper rear end of charge door by the upper end.

After adopting as above technical scheme, disintegrating machine is when crushing operation, after a fine grained chippings part of splashing is stopped by interior material blocking shade, its energy reduces greatly, the secondary of adding outer striker plate stops, makes outside its charge door that do not fly out handling safety, simultaneously, outer striker plate also is blocked in dust in the casing and does not cause dust pollution.

Preferably, outer striker plate is arranged continuously by the strip plate and is formed, the upper end of strip plate is provided with pan, be connected with bearing pin in the pan, bearing pin is positioned at the top of charge door, the body of wall that bearing pin passes the charge door both sides is connected by bolting, in the crushing operation process of pulverizer, can realize continuous charging, institute adds material and can only drive corresponding strip plate and swing in casing, and that the strip plate in all the other rooms just is in original position is motionless, makes the formed effective blocking surface best results of outer striker plate and material.

Preferably, the width of strip plate is 85～120mm, and the strip plate is too wide, and distortion back blocking effect is not good, and the strip plate is too narrow, can accelerate, and it is big, uneconomical to make workload.

Preferably, interior material blocking shade is arranged continuously by iron chains and is formed, be connected with bearing pin in the chain link of iron chains upper end, bearing pin is positioned at cabinets cavity end face below, bearing pin passes the side wall body in addition of a side wall body of casing, the iron chains of arranging continuously, casing successively, and is connected by bolting, and is simple in structure, easily manufactured, low cost of manufacture.

Preferably, the iron chains of arranging continuously is provided with spacer between two adjacent iron chains, and spacer is slidingly fitted in the bearing pin outside, and the two ends of spacer flexibly connect with adjacent iron chains respectively, and iron chains is arranged evenly, guarantees that further shelves expect an effect.

The utility model beneficial effect compared with prior art is, can be effectively splash fragment and dust intercepted in equipment with crushing operation produces, not having splashes hurts sb.'s feelings no dust pollution, safety, environmental protection, simple in structure, easily manufactured, low cost of manufacture.
