Abstract
The utility model discloses a hammer crusher comprising a rotor, a counter plate, a crushing plate, a discharge grate and a casing, wherein the casing comprises an upper casing and a lower casing; the discharge grate is arranged in the lower casing; the hammer crusher further comprises an iron removal protection device which comprises a movable grate and a counter weight; the middle part of the movable grate is articulated onto the lower casing at the rear part of the discharge grate; and the counter weight is arranged at one end of the movable grate. As the technical scheme is adopted and the iron removal protection device is arranged, the hammer crusher can remove iron parts entering into the machine by mistake without influence on the normal work of the hammer crusher, and can be safely and reliably operated; and wearing parts such as a hammer, the grates and the like have long service life.
Description
Technical field
The utility model relates to a kind of hammer mill.
Background technology
Hammer mill is used for broken general fragility ore, as lime stone, argillaceous siltstoue, shale, gypsum and coal etc., also is fit to crushed stone lime stone and argillaceous mixture.Main motor drives the rotor rotation that big belt wheel is housed by the joint group narrow V belt.Tup hits ore with higher linear velocity, smash or throw the material piece simultaneously, struck on the counterattack liner plate by the material piece thrown or collide certainly once more broken, brought by tup into continue to catch a packet in crushing shell and grate workspace then and when being crushed to less than grate seam size bottom, slave chamber discharge.But the ironware that is strayed in the machine can not in time be got rid of, liner plate, tup or other consumable accessory in the fragile housing.
The utility model content
Technical problem to be solved in the utility model provides a kind of hammer mill, can will be strayed into ironware in the machine get rid of and do not influence the operate as normal of hammer mill.
For solving the problems of the technologies described above; the utility model adopts following technical scheme: hammer mill; comprise rotor, counterpunch board, crushing shell, discharge grate, housing; described housing comprises upper shell, lower house; described discharge grate is located in the described lower house, also comprises the iron protective device, and the described iron protective device of crossing comprises movable grate, counterweight; the middle part of described movable grate is hinged on the lower house at described discharge grate rear portion, and described counterweight is located at an end of described movable grate.
Described movable grate is " L " shape, so that compact conformation.
Described upper shell, lower house are hinged, so that change liner plate, tup or other consumable accessory in the housing.
The utility model had the iron protective device owing to adopted technique scheme, can will be strayed into that ironware in the machine is got rid of and the operate as normal that do not influence hammer mill is safe and reliable.Consumable accessory such as tup, the grate life-span is long.
Description of drawings
Fig. 1 is the structural representation of the utility model hammer mill.
Fig. 2 is the discharge view of the utility model hammer mill.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is further described.
Figure 1 shows that the utility model hammer mill; comprise rotor 1, counterpunch board 2, crushing shell 3, discharge grate 4, housing; described housing comprises upper shell 5, lower house 6; described discharge grate 4 is located in the described lower house 6; also comprised the iron protective device; the described iron protective device of crossing comprises movable grate 7, counterweight 8, and the middle part of described movable grate 7 is hinged on the lower house 6 at described discharge grate 4 rear portions, and described counterweight 8 is located at an end of described movable grate 7.Described movable grate 7 is " L " shape.Described upper shell 5, lower house 6 are hinged.Discharge grate 4 is made by the wear resistant alloy material casting, and it is installed in the bottom of crusher rotor, and its rotor and discharge grate angle of contact gap can be regulated, and its gap is determined by the marker size size.
Figure 2 shows that the discharge state of the utility model hammer mill; movable grate 7 is hinged on the lower house at discharge grate rear portion; under the effect of spring; can stop the ore that is not broken to overflow; again can be under action of centrifugal force with the ironware in the machine of being strayed into; push movable grate rapidly open and discharge by crossing iron outlet 9 smoothly, movable subsequently grate 7 auto-closings needn't aim at this shutdown.
