Abstract
A hammer for a pulverizer difficult to form material blockage relates to mining crushing mechanical operation equipment, in particular to the technical structure field of a pre-pulverizer in a coal preparation working section of a coking enterprise. The lower part of the hammer body is provided with a connecting hole, the outer end of the working surface of the hammer body is provided with at least one groove, and the symmetrical center line of the groove is parallel to the axis of the connecting hole. When the equipment is operated, the phenomenon of material clamping between the hammer body and the impact lining plate can be avoided, the accumulated material of the impact lining plate can be cleaned in time, the equipment is ensured not to be blocked easily, the service life of the hammer head and the service life of the impact lining plate are prolonged, the production and operation cost is reduced, and the crushing efficiency is improved.
Description
Technical field
The utility model relates to the technical pattern field that a kind of mining size reduction machinery implement, particularly coking enterprise are equipped with coal workshop section prebreaker.
Background technology
Prebreaker is that coking enterprise is equipped with the anthracite of coal workshop section or the main broken equipment of other difficult broken material, existing prebreaker structure basic with general pulverizer, mainly material hit and realize fragmentation by being connected tup on the Hammer head assembly and the counterattack liner plate in the crusher chamber.In order to reach the smashing fineness of design, gap between the work outer face of tup and the counterattack liner plate is less, easily form the material clamping between tup outer face and the counterattack liner plate, not only be unfavorable for pulverizing, also can cause tup to rupture along the connecting hole position, form the production hidden danger that tup separates with hammer handle, cause counterattack liner plate profile of tooth impaired.
The utility model content
The utility model purpose is to design the pulverizer tup that a kind of difficult formation material blocks up, prolongs the pulverizer long service life for coking enterprise is equipped with coal workshop section prebreaker.
The utility model comprises hammer body, offers connecting hole in the bottom of hammer body, in the working face outer end of hammer body at least one groove is set, and the symmetrical center line of described groove is parallel with the axis of connecting hole.
Because above-mentioned design, when equipment moves, can avoid the material clamping phenomenon between hammer body and the counterattack liner plate to occur, can in time clear up counterattack liner plate buildup, guarantee that equipment is difficult for stopping up, be beneficial to the service life that prolongs tup and counterattack liner plate, reduce the production run cost, and help improving crushing efficiency.
Groove preferred version of the present utility model is a circular arc.
Description of drawings
Fig. 1 is a kind of structure intention of the present utility model.
The specific embodiment
As shown in Figure 1, connecting hole 2 is offered in hammer body 1 bottom.In the upper surface of hammer body 1 two parallel circular grooves 3,4 are set, the symmetrical center line of each groove 3,4 is parallel with the axis of connecting hole 2.
Claims (2)
1, the stifled pulverizer tup of a kind of difficult formation material comprises hammer body, offers connecting hole in the bottom of hammer body, it is characterized in that in the working face outer end of hammer body at least one groove being set, and the symmetrical center line of described groove is parallel with the axis of connecting hole.
2,, it is characterized in that the circular groove that is of described groove according to the described pulverizer tup of claim 1.
