During use, the fuel tap of opening hydraulic cylinder outwards stretches the piston in the cylinder, then crank promptly is being with damper shaft to rotate an angle, and the rotation of damper shaft has driven immediately that baffle plate fixed thereon is rotated in a clockwise direction downwards (representing that by solid line the position forwards on the position of double dot dash line as baffle plate in Fig. 1), baffle plate reduces the barrier height of rubbish, that is bed depth descends; On the contrary, fuel tap at the reverse opening hydraulic cylinder, so that the piston in the hydraulic cylinder cylinder in cylinder direction retraction, crank around the damper shaft backward rotation and driven immediately the baffle plate that is fixed on the damper shaft along rotation counterclockwise upwards (represent that by double dot dash line the position forwards on the position that solid line represents) as baffle plate in Fig. 1, the height of baffle plate on fire grate increase, the thickness of feed layer that is blocked on the fire grate thickens, thereby can prolong the burning time of rubbish on fire grate.

The bed depth adjusting device of embodiment 2, present embodiment incinerator, its structure can be seen from Fig. 2 and Fig. 4, different is driving mechanism with embodiment 1 for it, this driving mechanism is an Electric Drive mechanism, it comprises motor 7, decelerator 8, and is connected the mechanical transmission mechanism 9 between reducer output shaft and the damper shaft.The spiral gear drive mechanism that this mechanical transmission mechanism can be made up of a pair of helical gear, or the conical gear drive formed of a pair of conical gear, or Worm and worm-wheel gearing; Wherein in the spiral gear drive mechanism two helical gear place axle noon axis respectively with the output shaft and the damper shaft coaxial line of decelerator; The axis of two conical gear place axles in the conical gear drive respectively with the output shaft and the damper shaft coaxial line of decelerator; The output shaft coaxial line of the worm-wheel shaft in the Worm and worm-wheel gearing and damper shaft coaxial line, worm shaft and decelerator.Present embodiment has only been represented the mechanical transmission mechanism with Worm and worm-wheel gearing in Fig. 3, and does not represent spiral gear drive mechanism and conical gear drive.

Though more than the bed depth of two embodiment regulate dress stomach type of drive difference, they are identical to the damper shaft role, and baffle plate also can be in full accord to the effect of blocking of the bed of material.

To be example below with noon shown in Figure 5 forwards formula incinerator, the present embodiment bed depth regulating device that withers is further described below, to illustrate that this dress stomach is to island calorific value, low moisture house refuse or high-moisture, regulating action when the low heat value consumer waste incineration is handled.

Activity template in the forwards formula fire grate is consistent with snake rubbish noon direction of advance to the rubbing direction of rubbish section layer; That is to say, the reciprocating motion rod member in forwards formula fire grate be drive activity template backward, with during the branch force direction of rubbish deadweight is consistent to descending.The present embodiment bed depth joint dress stomach that withers is installed among Fig. 5 and the tail end of forwards formula fire grate, and the bottom righthand side of the fire grate among Fig. 5 10 just, the used bed depth regulating device that withers is to be driven by Electric Drive mechanism.When burning disposal high heating value, low moisture house refuse, can startup section layer height adjusting device; At this moment can open motor, and make damper shaft rotate an angle by the mechanical transmission mechanism 9 between decelerator and reducer output shaft and the damper shaft, immediately driven that baffle plate fixed thereon is rotated in a clockwise direction downwards, baffle plate reduces the barrier height of rubbish and the rotation of damper shaft is two, at this moment the lime-ash of forwards formula fire grate tail end under the fire grate segment promotion, fall in the slag releasing channel, rubbish bed of material attenuate gradually; Not only high heating value rubbish was fully burned but also had guaranteed the treating capacity of rubbish by this joint that withers.On the contrary, when burning disposal high-moisture, low heat value house refuse, but backward rotation motor, the baffle plate that is fixed on the damper shaft makes progress along counterclockwise rotating so that the damper shaft backward rotation has also driven immediately, the height of baffle plate on fire grate increases, the thickness of feed layer that is blocked on the fire grate thickens, thereby can prolong the burning time of rubbish on forwards formula fire grate; If accelerate the frequency of fire grate motion this moment more simultaneously, then can make in section's layer height scope of rubbish after this setting and fully be stirred, stir, burn, therefore and can not make rubbish under unburnt situation, just be pushed out forwards formula fire grate because of the quickening of fire grate motion frequency, guarantee the treating capacity and the hot burn decrement rate of burning disposal high-moisture, low heat value house refuse.In sum, when burning disposal high-moisture, low heat value house refuse, can improve the fire grate motion frequency to strengthen agitaion the clean-burning while, make rubbish enough time of staying be arranged on forwards formula fire grate, can not take out of outside the stove prematurely by heightening baffle plate to the barrier height of the bed of material again, thereby guarantee that incinerator burn-off rate under stable operating load still keeps lower hot burn decrement rate.If under the situation that refuse thermal value uprises, by reducing the island degree of baffle plate, the motion frequency of the fire grate that slows down can shorten the time of staying of rubbish in stove, can keep certain burning load again simultaneously, guarantees the disposal ability of rubbish.Therefore, the bed depth adjusting device of present embodiment incinerator guarantees under the prerequisite of garbage treatment quantity and hot burn decrement rate, can adapt to the bigger house refuse of burning disposal physics or calorific value fluctuation so that can also realize the incinerator of same model can the burning disposal zones of different, the house refuse of Various Seasonal, different weathers and obtain the combustion efficiency of setting.In addition, wither simple and reasonable, the simple to operation use of joint of present embodiment is reliable, and economic and few, the long service life of fault.
