The content of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art that there is provided a kind of simple in construction, screening effect is good
Adjustable smalls screening plant.
To achieve the above object, technical scheme provided by the utility model is：Adjustable smalls screening plant, it includes
The conveyer belt for having screening frame and being connected on rear side of screening frame, screening top of the trellis is located at provided with screening hopper, conveyer belt output end
Sieve above hopper, the screening frame top that screening feed hopper bottom is provided with below material outlet, material outlet is provided with dusting cover, and dusting cover inclines
Screening frame top is tiltedly fixed on, screening frame lower removable is provided with both sides at the top of scalping, scalping and is movably articulated in by synchronizing shaft
On screening frame below dusting cover, it is located at dusting cover bottom part down at the top of scalping after being hinged, scalping bottom is to lower section on front side of screening frame
Extension, its elongated end both sides are provided with adjustment axis, and adjustment axis outer end, which is provided with the top of axle sleeve, adjusting screw rod, is provided with handwheel, adjusting screw rod
The free bearing that bottom is passed down through after axle sleeve with screening frame bottom is connected, and bottom is provided with slag guiding trough, slag guiding trough position on front side of screening frame
In scalping bottom part down；The cleaned coal stock guide and rough coal stock guide being engaged with dusting cover, scalping are respectively equipped with rear side of screening frame, essence
Coal stock guide is located at below dusting cover, and rough coal stock guide is located at below scalping.
Described dusting cover gradient is more than scalping gradient.
Internal thread is provided with described axle sleeve, the internal thread is engaged with the screw thread on adjusting screw rod.
The sieve aperture of described dusting cover is less than scalping sieve aperture.
The utility model, by conveyer belt by smalls feeding screening hopper, passes through material outlet after using such scheme
Smalls is glided automatically, carrying out sublevel ladder by dusting cover and scalping during downslide screens, and the gradient of dusting cover is more than scalping
Gradient, while the mesh of dusting cover be less than scalping mesh, make scalping screening when, smalls can buffer and reduce lower terminal-velocity
Degree, while the gradient of scalping can be adjusted freely according to screening requirement, makes screening effect more preferably, can have in this way
Effect is by the duff in smalls and rough coal quick separating, and lump coal and stone for screening out etc. are exported by slag guiding trough；Using this programme
Simple in construction, screening effect afterwards is good, can be to the quick screening of smalls, and screen cloth is in screening without energy consumption.
Brief description of the drawings
Fig. 1 is overall structure diagram of the present utility model.
Fig. 2 is screening principle schematic of the present utility model.
Embodiment
With reference to all accompanying drawings, the utility model is described in further detail, and preferred embodiment of the present utility model is：Ginseng
See accompanying drawing 1 and accompanying drawing 2, the adjustable smalls screening plant described in the present embodiment includes screening frame 1 and is connected to screening frame 1
The conveyer belt 2 of rear side, the top of screening frame 1 is provided with screening hopper 3, and the output end of conveyer belt 2 is located at the top of screening hopper 3, screening material
3 bottoms struggle against provided with material outlet, the top of screening frame 1 below material outlet is provided with dusting cover 4, dusting cover 4, which is tilted, is fixed on screening frame 1
Top, the screening lower removable of frame 1 is provided with scalping 5, and the described gradient of dusting cover 4 is more than the gradient of scalping 5, the top of scalping 5 two
Side is movably articulated in by synchronizing shaft 6 on the screening frame 1 of the lower section of dusting cover 4, and the top of scalping 5 after being hinged is located under the bottom of dusting cover 4
Side, the bottom of scalping 5 extends to the front side lower section of screening frame 1, and its elongated end both sides is provided with adjustment axis 7, and the outer end of adjustment axis 7 is provided with axle sleeve
8, the top of adjusting screw rod 9 is provided with handwheel 10, and the bottom of adjusting screw rod 9 is passed down through the phase of free bearing 11 with screening frame 1 bottom after axle sleeve 8
Internal thread is provided with connection, described axle sleeve 8, the internal thread is engaged with the screw thread on adjusting screw rod 9, screening frame 1 front side bottom
Provided with slag guiding trough 12, slag guiding trough 12 is located at the bottom part down of scalping 5；The sieve aperture of described dusting cover 4 is less than the sieve aperture of scalping 5, sieves frame 1
Rear side is respectively equipped with the cleaned coal stock guide 13 and rough coal stock guide 14 being engaged with dusting cover 4, scalping 5, and cleaned coal stock guide 13 is located at
The lower section of dusting cover 4, rough coal stock guide 14 is located at the lower section of scalping 5.The present embodiment, by smalls feeding screening hopper, is passed through by conveyer belt
Material outlet glides smalls automatically, and carrying out sublevel ladder by dusting cover and scalping during downslide screens, the gradient of dusting cover
