In figure, 1-hopper, 2-screen cloth, 3-jointed shaft, 4-hinged-support, 5-permanent seat, 6-belt conveyer, 7-slide rail, 8-limit material baffle plate, the outlet of 9-coarse fodder, 10-transmission shaft, 11-face cam, 12-axle drive shaft.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described, but protection domain of the present utility model is not limited to the following stated.
As shown in Figure 1 and Figure 2, belt conveyer material screening device of the present utility model, comprise hopper 1 and the screen cloth 2 that is placed in this hopper 1 inside, described hopper 1 front portion is provided with coarse fodder outlet 9, described screen cloth 2 rear portions and hopper 1 sidewall is movable to be coordinated, and it is corresponding and be connected with jittering device that anterior position and coarse fodder export 9 position; In hopper 1 inside, be provided with the limit material baffle plate 8 being positioned at below screen cloth 2.Belt conveyer material screening device of the present utility model, by the cooperation of hopper 1, screen cloth 2, jittering device, jittering device is constantly shaken and is driven screen cloth 2 shakes, and coarse fodder sifts out recovery from coarse fodder outlet 9, fines leaks down from screen cloth 2, has improved the efficiency of feed separation; Material under 8 pairs of screen clothes of limit material baffle plate, 2 sieves plays buffer action, has alleviated the impulsive force of material to belt conveyer 6 belts, has improved safety performance.Avoid belt conveyer 6 belts to be directly subject to material impact, avoid belt to cause damage because impacting, reduced the possibility that safety misadventure occurs, improved the service life of load transfer device, and used the screening process of jittering device supplies, realized the automatic screening of material, do not needed human assistance, not only efficient, also saved cost simultaneously.The utility model is simple in structure, safe and reliable, can be used for loader one-time feeding, discontinuous feed operating mode, and the utility model load-carrying capacity large, be used for the occasion that operational throughput is larger.
Described limit material baffle plate 8 can be planar shaped or spill, but these two kinds of shapes can cause solid accumulation on limit material baffle plate 8, therefore as preferred mode, be that described limit material baffle plate 8 is arch, material cushions at the upper surface of arch limit material baffle plate 8 from screen cloth 2 falls down, then along both sides, slide on the belt of belt conveyer 6, reduced widely the impulsive force to belt, improved safety performance, compared with the impulsive force of spill or the easier dispersed material of planar shaped.
As preferably, described screen cloth 2 both sides, rear portion are provided with the jointed shaft 3 that runs through hopper 1 sidewall, the part normal-running fit that this jointed shaft 3 stretches out hopper 1 has corresponding hinged-support 4, by hinged-support 4, coordinate with jointed shaft 3, avoid jointed shaft 3 to act directly on hopper 1, improved whole belt conveyer material screening device mechanical characteristics.It should be noted that jointed shaft 3 can also coordinate with hinged-support 4 by bearing in order further to improve mechanical characteristics.
Described jittering device can be to realize by the sling anterior up-and-down movement of screen cloth 2 of hoisting device, but this mode complex structure, energy consumption is also high, and complicated operation, as preferred mode, be therefore that described jittering device comprises permanent seat 5, axle drive shaft 12, face cam 11, transmission shaft 10 and the slide rail 7 that is arranged on screen cloth 2 front portions; Described permanent seat 5 is positioned at outside hopper 1, and described face cam 11 1 end faces are fixedly connected with axle drive shaft 12, and the eccentric position of other end is fixedly connected with one end of transmission shaft 10, and the other end of this transmission shaft 10 coordinates with slide rail 7 transmissions; Described axle drive shaft 12 normal-running fiies, on permanent seat 5, when axle drive shaft 12 rotation, drive face cam 11 to rotate; Transmission shaft 10 rotates with face cam 11, thereby slide rail 7 is applied to application force, drives screen cloth 2 to shake up and down, has improved the efficiency of feed separation.
Described slide rail 7 can be realized by cylinder, but transmission shaft 10 when motion need larger motion amplitude could realize cylinder on lower wall apply application force, when the motion frequency of transmission shaft 10 is large, easily there was a mechanical failure, therefore as preferred mode, be that described slide rail 7 comprises two parallel steel bars that are fixed on screen cloth 2, described transmission shaft 10 is engaged among the cell body of two steel bars formation, between the end of two steel bars, be connected with the bearing pin that prevents transmission shaft 10 slippage when moving, the intensity of steel bar is higher, improved mechanical characteristics, the effect of bearing pin is mainly for preventing that transmission shaft 10 from skidding off from cell body.When transmission shaft 10 upwards pushes up the steel bar in top, screen cloth 2 upward movements, when transmission shaft 10 is depressed the steel bar in limit downwards, screen cloth 2 moves downward, quite convenient.It should be noted that, for making other clear in structure, do not skid off in the drawings bearing pin; Fit structure that it should be noted that steel bar and bearing pin can also adopt the Long Circle tubular structure being equal to realize.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
