Abstract
The utility model discloses an external cutter structure for a vertical impact crusher, which comprises a rotor shaft, a rotor shell and a plurality of outlets, wherein the rotor shell is sheathed n the rotor shaft; a plurality of outlets are radically and uniformly distributed from the inner surface of the rotor shell to the outer surface in the circumferential direction; a lining plate is respectively arranged in each outlet; external cutters are arranged at the outlets of the rotor shell; each external cutter is formed by three short external cutters with the same structure and the same width through split joint; and the three short external cutters are removably arranged at the outlets of the rotor shell in parallel at the top, the middle and the bottom, and are positioned at the outer ends of the lining plates. One external cutter at each outlet of the rotor is changed into three external cutters, i.e. the original long external cutter with large width is changed into three short external cutters, and the length of each short external cutter accounts for 1/3 of that of the original long external cutter. When the middle short external cutter is severely abraded, the upper short external cutter and the lower short external cutter can be continuously used, at the time, only the middle short external cutter needs to be changed, the operating cost is saved, and the materials are also saved.
Description
Technical field
The utility model relates to a kind of outer knife structure that is used for vertical impact crusher.
Background technology
Vertical impact crusher is applicable to the making abrasive material, refractory material, cement, quartz sand, steel sand, stove quarrel powder, copper mine stone, iron ore, auriferous ore, cobble, aggregate, asphalt aggregate etc. are multiple, crisp material in small, broken bits with in broken, be a kind of efficient, energy-conservation rubble system sand equipment.Building stones directly fall into the high speed rotor rotated by machine top, under the effect of high speed centrifugation power, the counterpunch board of shunting around rotating disk in the umbellate form mode with another part produces high-speed bump and highdensity pulverizing, building stones are after hitting mutually, can between rotor and frame, form eddy motion again and cause repeatedly mutual strike, friction, pulverizing, the straight-through discharge from the bottom.
The vertical impact crusher of enclosed rotor is housed, and an outer cutter that studs with carbide alloy generally all is equipped with in each exit in its rotor.Outer cutter belongs to consumable accessory, in case damage, for guaranteeing to run well and discharging-material size, just must change, so change more frequent.As shown in Figure 1, rotor comprises rotor case 1, outer cutter 2, and outer cutter 2 usefulness bolts 3, nut 4 are fixed on the rotor case, and liner plate 5 also is housed in the rotor case 1.As shown in Figure 2, a general exit is equipped with an outer cutter 2 that width is suitable, but the wear law that is somebody's turn to do outer cutter 2 is that center-top at first weares and teares, along with the increase wearing and tearing of service time are more and more serious, and the position is worn and torn seldom up and down, but this moment, because crushing effect is poor, so must be whole replacing, so operating cost be higher.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiencies in the prior art, a kind of outer knife structure that is used for vertical impact crusher that is easy to realize to be provided, and it had both saved operating cost, had also saved material.
A kind of technical scheme that realizes above-mentioned purpose is: a kind of outer knife structure that is used for vertical impact crusher, comprise armature spindle, be sleeved on the rotor case on the armature spindle, be uniformly distributed along the circumference leading thread to offering some exits from the inner surface of rotor case to outer surface, one liner plate is installed respectively in these exits, cutter outside the exit of rotor case is provided with, wherein, described outer cutter is spliced by the outer cutter of the three bar structures weak point identical with width, and they are removably mounted in the exit of rotor case and are positioned at the outer end of liner plate in upper, middle and lower mode arranged side by side.
The technical scheme that is used for the outer knife structure of vertical impact crusher of the present utility model, adopted an outer cutter in each exit of rotor has been made into three, promptly the outer cutter of the bigger length of width is made into the outer cutter of three weak points to original one, every length short outer cutter is 1/3rd of original long outer cutter.When middle one short outer cutter is worn and torn when very serious, two can also continue short outer cuttves to use up and down, and also saved material as long as outer cutter of weak point in the middle of changing has been saved operating cost this moment.
Description of drawings
Fig. 1 is the rotor structure schematic diagram of the vertical impact crusher of prior art;
Fig. 2 is the schematic diagram of the outer knife structure that is used for vertical impact crusher of prior art;
Fig. 3 is the schematic diagram that is used for the outer knife structure of vertical impact crusher of the present utility model.
The specific embodiment
In order to understand the technical solution of the utility model better, below by embodiment particularly and be described in detail in conjunction with the accompanying drawings:
See also Fig. 2, the outer knife structure that is used for vertical impact crusher of the present utility model, comprise armature spindle 1, rotor case 2, liner plate 3 and outer cutter 4, wherein, rotor case 2 is sleeved on the armature spindle 1, rotor case 2 be uniformly distributed along the circumference leading thread to offering some exits 20 from inner surface to outer surface, liner plate 3 is installed in these exits 20, outer cutter 4 is installed in the exit of rotor case 2.
The characteristics that are used for the outer knife structure of vertical impact crusher of the present utility model are: outer cutter 4 is spliced by the outer cutter 40 of the three bar structures weak point identical with width, and they are removably mounted in the exit 20 of rotor case 2 and are positioned at the outer end of liner plate 3 by bolt 5 and nut 6 in upper, middle and lower mode arranged side by side.
The outer knife structure that is used for vertical impact crusher of the present utility model has adopted an outer cutter in each exit of rotor has been made into three, promptly the outer cutter of the bigger length of width is made into the outer cutter of three weak points to original one, every length short outer cutter is 1/3rd of original long outer cutter.When middle one short outer cutter is worn and torn when very serious, two can also continue short outer cuttves to use up and down, and also saved material as long as outer cutter of weak point in the middle of changing has been saved operating cost this moment.
Those of ordinary skill in the art will be appreciated that, above embodiment is used for illustrating the utility model, and be not to be used as qualification of the present utility model, as long as in connotation scope of the present utility model, all will drop in claims scope of the present utility model variation, the modification of the above embodiment.
