According to another aspect of the present invention, provide a kind of flotation device guillotine mechanism, it is characterized in that, in the both sides of flashboard, be respectively equipped with a guide rail being vertically fixed on tailing tank, this flashboard can slide up and down to coordinate with two guide rails; And tailing tank is fixed on cell body; Above flashboard, be provided with restrictor bar, the edge of the cross section of this restrictor bar comprises at least one straightway, and the top of this restrictor bar is provided with worm gear tooth-strip part, and this restrictor bar can slide up and down to coordinate with the fairlead being fixed on cell body; At the worm gear tooth-strip part on the top of restrictor bar, be provided with the worm screw portion being meshed, this worm screw portion is fixed on and adjusts on axle, and this adjustment axle is supported by least two supporting seats that are fixed on cell body, in one of them supporting seat, being provided with can be with respect to the axle sleeve of adjusting axle slip but can not rotate; Be provided with sleeve end profile of tooth in the end of this axle sleeve, end face in supporting seat is provided with supporting seat inner face profile of tooth, between sleeve end profile of tooth and supporting seat inner face profile of tooth, there is the position of engagement and disengaged orientation, in the position of engagement, axle sleeve is with respect to adjusting shaft locking, and flashboard is in preventing the operating mode of downslide; At disengaged orientation, axle sleeve departs from engagement with respect to adjusting shaft locking, and handwheel is in rotatable operating mode, and flashboard is in adjustable operating mode.
Preferably, this adjustment axle is supported by least two supporting seats that are fixed on cell body.
Preferably, described in this, the two ends of worm-gear toothing are respectively provided with a supporting seat holder of adjusting axle, are provided with handwheel at the outboard end of the cell body of adjusting axle.
Preferably, be provided with worm-gear toothing in one end that is positioned at cell body middle part of adjusting axle, be provided with handwheel at the other end of adjusting axle.
Preferably, described rail welding is on described tailing tank, or the cross section of this restrictor bar is trapezoidal, square or rectangle.
According to one embodiment of present invention, adopt rack and pinion engagement pair, the lifting of flashboard is adjusted, adjustment handwheel is positioned at the outside of flotation device, is therefore easy to adjust.
According to the present invention, overcome prejudice of the prior art, evade and overcome a series of technical difficulties, successfully the adjustment handwheel of the flashboard of flotation device is changed into the outside of flotation device from the middle part of cell body, the flashboard leading screw of flotation device is adjusted to structure and change rack-and-pinion guiding mechanism or worm gear structure into, the handwheel of the flashboard of flotation device is changed into vertical operation by levels operation, make thus the adjustment operation of flashboard become very convenient.

Detailed description of the invention
As Figure 1-3, flashboard 4 is between two guide rails 3, and guide rail 3 is welded on tailing tank 2, and tailing tank 2 is fixed on cell body 1.On flashboard 4, be fixed with restrictor bar 5, restrictor bar 5 is square, and the top of restrictor bar 5 is processed with tooth bar.Restrictor bar 5 is enclosed within the fairlead 10 being fixed on cell body 1, and restrictor bar 5 and flashboard 4 slide up and down respectively in fairlead 10 and guide rail 3.Gear 9 is meshed with the tooth bar on restrictor bar 5 tops, and gear 9 is fixed on to be adjusted on axle 6, adjusts 6, axle and is held by two supporting seats 7, and supporting seat 7 is fixed on cell body 1.
In one embodiment of the invention, one end of adjusting axle is provided with gear, is fixed with handwheel 8 at the other end of adjusting axle 6.In another one embodiment of the present invention, the middle part of adjusting axle is provided with gear and is fixed with handwheel 8 in the time that needs are adjusted flashboard lifting at the outboard end of adjusting axle 6, only need to rotate handwheel, thus driven gear rotation, by the engagement of rack-and-pinion, thereby make restrictor bar flashboard realize lift adjustment.By above mode, can adjust flashboard easily.
As shown in Figure 3, in one embodiment, the both sides of flashboard 4 are engaged in respectively the guide groove of two side rails 3, and restrictor bar 5 is engaged in guide pin bushing 51, the edge of the cross section of this restrictor bar 5 comprises at least one straightway 52, and the top of this restrictor bar is provided with tooth-strip part or worm gear tooth-strip part on this straightway 52.
Because pinion and rack itself cannot self-locking, flashboard may fall under the effect of deadweight, therefore, needs a sleeve locking apparatus.
As shown in Fig. 4-5, can in the close supporting seat of handwheel side, add locking device.
Particularly, near in the supporting seat 11 of handwheel side, an axle sleeve 13 is housed, on axle sleeve 13, be processed with screw thread, holding screw 12 is installed, the end of holding screw 12 coordinates with the elongated slot processing on adjustment axle 6, like this, this axle sleeve 13 can adjusted slip on axle 6, and can not rotate.End at this axle sleeve 13 is processed with profile of tooth, and this profile of tooth matches with the profile of tooth that the end face of supporting seat 11 processes.In the time that needs are adjusted flashboard, only axle sleeve 13 need be pulled out, its profile of tooth and supporting seat are departed from, just can rotate handwheel, regulate flashboard.After adjusting completes, axle sleeve 13 is pushed to supporting seat 11, profile of tooth is engaged with supporting seat, axle sleeve 13 cannot rotate, and equally also making to adjust axle 6 cannot rotate, and has so just locked tooth bar.
