Abstract
The utility model discloses a wear-resistant grid screen of a movable-type coarse crushing ore supply bin. The wear-resistant grid screen of the movable-type coarse crushing ore supply bin comprises wear-resistant grid screens fixed on a support seat, wherein the lower part of the support seat is provided with wheels; an ore supply area and an overhauling area are respectively provided with tracks, and the tracks are matched with the wheels; check blocks are respectively arranged at the two sides of each track; the track between the ore supply area and the overhauling area is provided with a switching-type limiting device; the wear-resistant grid screen is formed by punching in the middle of a steel track, a piece of round steel passes through a hole arranged in the middle of the steel track, and a seamless steel tube is sheathed on the round steel. The wear-resistant grid screen of the movable-type coarse crushing ore supply bin, which is provided by the utility model is reasonable in configuration, convenient to operate, low in maintenance load, high in operation rate and beneficial to guaranteeing the smooth production.
Description
Technical field
The utility model belongs to the technique of preparing field, is specifically related to a kind of portable coarse crushing of controlled fragmentation feed preparation unit size to the wear-resisting diagrid of ore storage bin.
Background technology
Along with iron ore beneficiating factory maximizes, the not section expansion of opencast mining scale, also increasing with lumpiness by the amount of the ore ore deposit after the stope fragmentation.The ore dressing plant single stage crushing is used jaw crusher mostly at present, if excessive lumpiness ore enters disintegrating machine, will cause damage to disintegrating machine, accelerates the wearing and tearing of liner plate, reduces operating rate and the service life of equipment.Much select at present factory to reinforce the fixed pattern diagrid before single stage crushing is to ore storage bin, for guaranteeing service life, diagrid often adopts rail welding to form, but still only there is 2-3 month its service life, wear and tear very serious, need 1-2 days and again repair the welding diagrid, the blocking phenomenon occurs often simultaneously, has a strong impact on and selects factory to produce.Do not use diagrid so much select at present one section, factory to grind front ore storage bin, adopt ore that factory comes and unloaded in the coarse crushing ore storage bin by automobile straight, so use the impact according to mine-feeding equipment under paired ore storage bin and disintegrating machine for a long time, restricted too production stability.
The utility model content
In order to overcome above-mentioned defect, technical problem to be solved in the utility model is to provide a kind of simple in structure, practical portable coarse crushing to the wear-resisting diagrid of ore storage bin.Traditional by the diagrid form of rail welding anyhow, increase the wear-resisting effect of its diagrid, postpone its service life by changing, the 2nd, can remove diagrid and carry out patch work in other place when diagrid may wear to out of use the time, so just can not impact production, guarantee the disintegrating apparatus operating rate.
The technical solution of the utility model is achieved in that
The portable coarse crushing of the utility model is to the wear-resisting diagrid of ore storage bin, comprise the wear-resisting diagrid be fixed on bearing, it is characterized in that: in the bearing bottom, road wheel is installed, the track of matching to mining area with the setting of maintenance district with wheel in coarse crushing to ore storage bin, the track both sides arrange block, in coarse crushing, to giving on the track between mining area and maintenance district of ore storage bin, the switching regulator stopping means are set.
Described wear-resisting diagrid is by the steel rail type reinforcement of middle perforate, and through the round steel of steel rail type reinforcement interstitial hole, covering device seamless steel pipe on round steel forms.
The utility model has the advantages that: owing to having increased seamless steel pipe on diagrid, by seamless steel pipe, can be rotated along with ore supplied materials direction, offset most of ore impulsive force, the protection compass screen surface, increase its service life.The while portable grizzly can make diagrid and carry out repairing work in the situation that do not affect production by move to the maintenance district to the ore storage bin district.
The utility model configuration is reasonable, easy to operate, operate steadily reliable, maintenance is little, operating rate is high, be conducive to ensure produce and carry out smoothly.
The accompanying drawing explanation
Fig. 1 is that the portable coarse crushing of the utility model is to the wear-resisting diagrid structural representation of ore storage bin.
Fig. 2 is the wear-resisting diagrid partial enlarged drawing in Fig. 1.
Wherein, wear-resisting diagrid 1, bearing 2, wheel 3, track 4, block 5, stopping means 6, seamless steel pipe 1-1, round steel 1-2, steel rail type reinforcement 1-3.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described further:
As shown in Figure 1, 2, the portable coarse crushing of the utility model is to the wear-resisting diagrid of ore storage bin, comprise the wear-resisting diagrid 1 be fixed on bearing 2, it is characterized in that: in bearing 2 bottoms, road wheel 3 is installed, the track 4 of matching to mining area A with maintenance district B setting with wheel in coarse crushing to ore storage bin, the track both sides arrange block 5, in coarse crushing, to giving on the track 4 between mining area A and maintenance district B of ore storage bin, switching regulator stopping means 6 are set.
Described wear-resisting diagrid 1 is by the steel rail type reinforcement 1-3 of middle perforate, and through the round steel 1-2 of rail 1-3 formula reinforcement interstitial hole, covering device seamless steel pipe 1-1 on round steel 1-2 forms.
Diagrid 1 adopts seamless steel pipe 1-1, round steel 1-2 and steel rail type reinforcement 1-3 to be made, perforate in the middle of steel rail type reinforcement 1-3-, round steel 1-2 is passed from steel rail type reinforcement 1-3 interstitial hole, and cover seamless steel pipe 1-1 on round steel 1-2, finally complete diagrid and make simultaneously.
Track 4 is by extend to diagrid maintenance district B to ore storage bin district A always.The track both sides all arrange limited block 5, with maintenance district B is middle, switching regulator stopping means 6 are being set to mining area A simultaneously, in order to prevent diagrid unexpected generation in producing or overhauling.
Portable coarse crushing of the present utility model to the operation principle of the wear-resisting diagrid device of ore storage bin is: system works can be divided into two kinds of situations basically:
During normal production, when unloading the ore deposit automobile and coming ore deposit to feed diagrid, seamless steel pipe 1-1 can be rotated along with ore supplied materials direction, offsets most of ore impulsive force, and the protection compass screen surface, increase its service life.Because seamless steel pipe 1-1 can rotate, simultaneously diagrid is also can local micro-movement aborning, can prevent that like this blocking phenomenon from appearring in ore on diagrid.
When the diagrid wearing and tearing are more serious, can open stopping means 6 and make diagrid go out the ore storage bin top by integrated moving, enter into diagrid maintenance district B and carry out Maintenance and Repair.The basic replacing seamless steel pipe 1-1 that only needs of diagrid maintenance.Now produce and can proceed (because the repair time is short, lump ore is little to the follow-up equipment shock effect).
