Abstract

The utility model relates to a counter-beating hammer-type crusher, which belongs to the technical field of a crusher. The utility model is mainly composed of a transmission shaft, a rotor, a beating hammer, a semicircular upper protecting plate, a lower sieve plate and a feed port, wherein, a counter-beating plate, the cross section of which forms a trapezoid, is arranged on the inner wall of the semicircular upper protecting plate. The utility model simultaneously uses acting force and reaction force to apply work to crush stone materials, and thus the utility model has very high work efficiency; the yield in per hour is increased by 25 percent; electricity is saved by 50 percent; meanwhile, the utility model also solves the problem that the material flies out of the feed port. The utility model is especially suitable for being used as a device for manufacturers to mixing expressway materials.

Description

Counter beating hammer type disintegrator

The utility model relates to a kind of counter beating hammer type disintegrator that belongs to general crushing technology field.

At present, rubble processing disintegrating machine mainly contains two kinds: hammer mill and impact breaker.Hammer mill is to utilize force principal, finishes rubble processing by forehand, and its working forms is that power drives tup by power transmission shaft and impacts building stones, when building stones are smashed certain particle size, fall the operating room from the grating gap location beyond, finish rubble processing.Yet because building stones enter the disintegrating machine operating room is motion state, when tup impacts building stones, some is broken, but some does not have broken yet, but under the effect of tup forehand power, in the operating room, fly, after active force consumed, building stones drop into the position that tup can impact again to be continued to impact, up to building stones smash can fall outside the operating room from the grating gap till.Be not difficult to find out that when tup impacted building stones and building stones are smashed, power had been done effective merit, and tup is not smashed building stones and building stones are beaten when flying, power has been done lost work.Therefore hammer mill is when work, and the power that is consumed have only part to do effective merit, and another part has been done lost work.Impact breaker is to utilize the reaction force principle, finishes rubble processing by the counterattack form.Its working forms is that power drives rotor by power transmission shaft, and the building stones that enter in the operating room are thrown flight, hits fixing counterpunch board, utilizes reaction force that building stones are smashed.When building stones bump against on the counterpunch board, some building stones is crashed to pieces, and also some building stones hits counterpunch board and is not crashed to pieces, and by rotor it is thrown to counterpunch board again after falling into the operating room, up to building stones smash to a certain degree fall outside the operating room till.We are not difficult to find out equally, when power drives rotor by power transmission shaft building stones are thrown to counterpunch board, and building stones have been done effective merit by the part power that reaction force smashes, and the part consumption of power that does not smash building stones has been done lost work.As mentioned above, hammer mill and impact breaker are two kinds of diverse operation principles, but have a common problem, and that is exactly that the part of the power that consumed has been done lost work, and operating efficiency is not high.The lost work that bell formula disintegrating machine is done but is the necessary condition of impact breaker work done.If therefore forehand is used in the operating efficiency that just can greatly improve disintegrating machine with two kinds of operation principles of counterattack.

The purpose of this utility model provides a kind of high efficiency counter beating hammer type disintegrator for solving disadvantages of background technology exactly.

The purpose of this utility model be achieved in that the utility model mainly by power transmission shaft, rotor, be located at epitrochanterianly impact hammer, semicircle upper guard board, sieve plate, charging aperture are formed down, being provided with the cross section on semicircle upper guard board inwall is trapezoidal counterpunch board.The cross section of counterpunch board is asymmetric trapezoidal.The cross section of following sieve plate is an arc.Charging aperture is located at the disintegrating machine following side.

The utility model is compared background technology and is had following advantage: 1, energy-conservation: economize on electricity 50% compared with similar products; 2, the wedge angle slabstone content of the rubble processed of this machine is less than 15%, and is the multiple edge body shape, meets highway materials standard; Output improves 25% when 3, single compared with similar products; 4, feed size is big; 5, charging aperture does not outwards fly material.

Fig. 1 is the utility model structure principle chart.

The utility model is further described by embodiment below in conjunction with accompanying drawing:, must guarantee that it all is effective merit that power is transmitted to operating room institute work in the design for realizing the work done simultaneously of active force and reaction force.As shown in Figure 1, active force drives rotors 3 by power transmission shaft 4 and the bell 5 that impacts that is located on the rotor 3 impacts building stones, utilizes force principal by the broken building stones of forehand power, and the building stones that will not smash hit and fly simultaneously.It is asymmetric trapezoidal counterpunch board 2 that the inwall of semicircle upper guard board 1 is provided with many cross sections, when building stones are hit when flying, no matter which angle of saequential transmission moving axis 4 direction of rotation is dished out, can strike on the counterpunch board 2 of relative angle with it, this is to utilize the reaction force principle by the broken building stones of counterforce.Following sieve plate 6 is designed to rectangle, and the cross section is an arc, has increased the effective blanking area of grating, reduces resistance material, improves process velocity.Charging aperture 7 designs are in the following side, operating room, owing to sieve plate 6 is curved down, increased the space of operating room, charging aperture 7 is designed in big position, space, operating room, processed building stones are entered behind the operating room just fully and impact hammer 5 and bump against and impacted, thereby thoroughly solved the difficult problem for many years that charging aperture 7 outwards flies to expect effectively.
