Description
[technical field]
The utility model relates to a kind of impact breaker, especially relates to a kind of main shaft and rotor and adopts no key expansion sleeve type to be connected, to strike back gap adjustment between liner plate and the rotor bar to be provided with and to insure spacing and strike back on the hook of frame hanging scroll safety-type impact breaker with anti-slip device.
[background technology]
Impact breaker is widely used in the raw material fragmentation of industries such as metallurgy, mine, building materials, highway, railway, cement and chemical industry, its kind model is a lot, and traditional impact breaker main shaft all adopts the keyway formula to be connected with rotor, make and just bear the very torsional strength weakening of the main shaft of high pulling torque originally, influenced the service life of equipment, the difficulty of main shaft and rotor mounting or dismounting simultaneously, inconvenient maintenance.Traditional in addition impact breaker lacks the anti-slip device of effective hanging scroll, comes off because counterattack frame integral body appears in bank top effect easily; Moreover the adjustment of counterattack frame does not have spacing safeties, reduce to strike back liner plate and rotor bar gap in adjusting, when changing the specification of finished product materials, make counterattack liner plate and the direct collision of rotor bar, cause equipment badly damaged so that jeopardize the serious accident of personal safety because adjustment amount is excessive.
[utility model content]
In order to overcome the above-mentioned shortcoming of prior art, the utility model provide a kind of torsional strength big, connect fastening reliable, maintenance mounting or dismounting simple and convenient, long service life, safe and reliable to operation, can effectively prevent to strike back frame integral body and come off and prevent to strike back the safety-type impact breaker that liner plate and rotor bar collide.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of safety-type impact breaker, comprise afer bay and rotor, be welded on the afer bay with the hook of anti-slip insurance card, hanging the counterattack frame by hanging scroll on the hook, stud with the counterattack liner plate on the counterattack frame, the counterattack frame draws by suspension adjusting bolt, adjustment nut and spring and leans against on the frame, hang to regulate on the bolt insurance spacer pin is housed, on the rotor outer rim bar is housed, rotor central authorities adopt expansion set to be connected with main shaft, and power links to each other between the big belt pulley of an end of main shaft and the motor.
Described frame is made up of forebay, afer bay and lower support three parts.
Described main shaft two ends are equipped with bearing and together are installed on the lower support with bearing block.
The big belt pulley of described main shaft one end links to each other with small belt pulley power on the motor by belt.
Form crusher chamber between described rotor bar and the counterattack liner plate.
The beneficial effects of the utility model are: main shaft adopts no key expansion sleeve type to be connected with rotor, and it is high by about 30% that the main shaft torsional strength connects type than other keyway formula of the same type, can effectively prolong the service life of equipment; Main shaft and rotor adopt no key expansion sleeve type to be connected, connects fastening reliably, keep in repair and install and remove simple and convenient; Be hung with forward and backward, following three counterattack framves on the frame separately, hang on the hook the anti-slip insurance card of hanging scroll is housed, regulate the spacing safeties of adjustment are arranged on the Hanging bolt of using in counterattack liner plate and rotor bar gap, can effectively prevent to strike back frame integral body comes off, prevent to strike back the collision of liner plate and rotor bar, so that cause equipment badly damaged and jeopardize the serious accident of personal safety.
[description of drawings]
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the side view of Fig. 1.
Among the figure: 1-afer bay, 2-hook, the anti-slip insurance card of 3-, 4-hanging scroll, 5-adjusts nut, and 6-hangs and regulates bolt, and 7-insures spacer pin, 8-spring, 9-strikes back frame, and 10-strikes back liner plate, 11-abrasionproof liner plate, 12-lower support, the 13-bar, 14-rotor, 15-forebay, 16-bearing, the 17-bearing block, 18-expansion set, 19-main shaft, 20-small belt pulley, the 21-belt, 22-big belt pulley, 23-motor.
[specific embodiment]
Below in conjunction with drawings and Examples the utility model is further specified.
Referring to Fig. 1 and Fig. 2, a kind of safety-type impact breaker, comprise afer bay 1 and rotor 14, be welded on the afer bay 1 with the hook 2 of anti-slip insurance card 3, hanging three counterattack framves 9 by hanging scroll 4 on the hook 2, stud with counterattack liner plate 10 on the counterattack frame 9, counterattack frame 9 is regulated bolt 6 by hanging, adjustment nut 5 and spring 8 draw and lean against on the frame, hang to regulate insurance spacer pin 7 is housed on the bolt 6, on rotor 14 outer rims bar 13 is housed, rotor 14 central authorities adopt expansion set 18 to be connected with main shaft 19, main shaft 19 two ends are equipped with bearing 16 and together are installed on the lower support 12 with bearing block 17, big belt pulley 22 adopts expansion sets to be fixed on a far-end of main shaft 19, and big belt pulley 22 links to each other with small belt pulley 20 power on the motor 23 by belt 21.
Operation principle of the present utility model is: motor 23 drives belt 21 and big belt pulley 22, drive rotor 14 and the bar on it 13 rotation at a high speed, when material enters the frame crusher chamber, be subjected to being fixed on rotor 14 support bodys impact of the bar 13 that is rotating at a high speed immediately and fragmentation, the material that is broken obtains very high movement velocity thus, strike on the counterattack liner plate 10 that is installed on the rotor 14 and be broken once more, rebound from counterattack liner plate 10 again then, clash into mutually with bar 13 on the rotor 14 and the material of dishing out by rotor 14 strikes, therefore material is at rotor bar 13, the intense impact that formation goes round and begins again in the crusher chamber between the counterattack liner plate 10 is collided and is broken, be crushed to desired particle size up to material, discharge by the machine bottom.The utility model counterattack frame 9 all is to adopt the dead-weight suspended structure, and when host work, counterattack frame 9 relies on the effect of deadweight and spring force to keep its normal operation position; As superhard thing by the time, counterattack frame 9 retreats rapidly, treat that hard thing is got rid of after, return former operating position again.The utility model counterattack frame 9 adopts hanging scroll 4 to be suspended on the hook 2, band anticreep insurance card 3 is housed on the hook 2, anticreep insurance card 3 is carried out effectively sealing to hanging scroll 4 mobile spaces, can prevent to strike back frame 9 under irregular external force effects such as the crowded top of material, from linking up with slippage on 2, cause equipment badly damaged accident together with hanging scroll 4.Counterattack liner plate 10 can be regulated by the suspension adjusting bolt 6 that is connected on the counterattack frame 9 with the gap between the rotor bar 13 on the utility model counterattack frame 9, improper for preventing to regulate, hang to regulate insurance spacer pin 7 is housed on the bolt 6, and be provided with two limit thereon respectively and adjust spacing position, make new, when old counterattack liner plate 10 in use is adjusted to extreme position, all and 13 of rotor bars leave suitable gap, wherein inner one spacing be to use when new counterattack liner plate 10 is installed, outer one spacing be for counterattack liner plate 10 use may wear to a certain degree after, do to use when secondary is adjusted, like this when counterattack liner plate 10 is fully used, can effectively prevent to strike back liner plate 10 and 13 direct collisions of rotor bar again, prevent that dangerous accident from taking place.
