Abstract
The utility model discloses a combined type rotor used in a strong impact breaker. The combined type rotor comprises a hollow rotor support, a main shaft connected inside the rotor support, a plurality of flat hammers arranged on the cylindrical surface of the rotor support and a belt pulley arranged on one end of the main shaft, wherein each flat hammer is a rectangular body, and both surfaces of the rectangular body are provided with a plurality of protruding triangular plugs; and one surface of each flat hammer is provided with a plug positioned in the height center line of the flat hammer, while the other surface is provided with two plugs which are symmetrical with the height center line. Because the technical proposal of the combined type rotor of the strong impact breaker is adopted, that is, both side faces of each flat hammer are provided with the symmetrical plugs, when one end of each flat hammer is worn to a limit position and requires replacement, the flat hammer can be turned upside down so as to be used for the second time, thereby prolonging the service life of the flat hammers on a rotor body and reducing production cost.
Description
Technical field
The utility model relates to a kind of composite fabricated rotor that is used for strong counterattack crusher.
Background technology
Aspect construction such as water power, urban architecture, highway, railway, need a large amount of construction materials, these raw materials not only need certain rigidity, and the finished product after the processing is cube, and faller gill shape content is few.Impact breaker is that the bar by being installed in high speed rotary on the rotor produces impact fragmentation and acceleration to the machined material that enters disintegrating machine, and makes and be accelerated building stones and be broken in throwing repeatedly, the bounce-back process between counterpunch board and bar.Rotor is the power core of impact breaker, and its design has extremely important influence to the task performance of disintegrating machine.Epitrochanterian bar is the vitals of impact breaker, and epitrochanterian bar shape is generally cuboid, during use, be connected by draw-in groove between bar and the rotor block, when broken and the material contact area big, and along with the wearing and tearing of bar, bar working sections area diminishes, be pointed shape, make the gap between itself and the counterpunch board become big, can not effectively impact that the discharging particle diameter is also inhomogeneous to building stones, influence the discharging quality greatly, at this moment must change bar.General always wear and tear fully less than eight at the quilt of bar/change for the moment, the bar after the replacing has just been scrapped, and is becoming waste of material, production cost height.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiencies in the prior art, a kind of composite fabricated rotor that is used for strong counterattack crusher is provided, it can may wear to can spin upside down when extreme position need be changed one of bar carries out the secondary use, thereby in the service life of bar on the prolongation rotor block, reduce production cost.
The technical scheme that realizes above-mentioned purpose is: a kind of composite fabricated rotor that is used for strong counterattack crusher, comprise hollow rotor rack, be connected in main shaft in the rotor rack, be located at the belt pulley that several bars and on the rotor rack face of cylinder are located at main shaft one end, described bar is a cuboid, be equipped with some outstanding triangular shape plugs on its two surfaces, a surface of described bar is provided with an outstanding plug that is positioned on its height center line, and it is to be arranged with two outstanding plugs that another surface is gone up with its height center line.
The above-mentioned composite fabricated rotor that is used for strong counterattack crusher, wherein, described bar is fixed on the rotor rack by the compact heap that is provided with the slot that mates with the bar plug.
The above-mentioned composite fabricated rotor that is used for strong counterattack crusher, wherein, the material of described bar is rich chromium cast iron KmTBCr26.
The above-mentioned composite fabricated rotor that is used for strong counterattack crusher, wherein, the wheel rim of described belt pulley is provided with the caulking groove of several V-types.
Owing to adopted the technical scheme that is used for the composite fabricated rotor of strong counterattack crusher of the present utility model, promptly on the bar two sides, be provided with the plug of symmetry, when making one of bar may wear to extreme position need to change, can spin upside down and carry out the secondary use, thereby in the service life of bar on the prolongation rotor block, reduce production cost.

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. 1 to Fig. 4, a kind of composite fabricated rotor that is used for strong counterattack crusher of the present utility model comprises main shaft 1, rotor rack 2, several bars 3, diaxon bearing 4 and belt pulley 5, wherein, rotor rack 2 is a hollow body, and it is sleeved on the middle part of main shaft 1; Diaxon bearing 4 is located at two of main shaft 1 respectively, and belt pulley 5 is located at an end of main shaft 1, and the wheel rim of belt pulley 5 is provided with 12 V-type caulking grooves 50, and motor is by narrow V belt, and four three joint groups drive rotor main shaft 1 and rotate, and make rotor transmission balance reliable; Bar 3 has eight, on the periphery of rotor rack 2 radially uniform four and be provided with two at the length direction of rotor rack 2.
The material of bar 3 is rich chromium cast iron KmTBCr26, it is a cuboid, be equipped with some outstanding triangular shape plugs 30 on its two surfaces, a surface that is bar 3 is provided with a plug 30 that is positioned on its height center line, and go up with its height center line to being arranged with two plugs 30 on another surface.
The composite fabricated rotor that is used for strong counterattack crusher of the present utility model in use, when of bar 3 may wear to certain degree, can pull down bar 3, transferring a stature to reinstall just can use by secondary, thereby prolonged the service life of bar 3, made the operating efficiency of disintegrating machine significantly improve.
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.
