Number sprocket wheel 65 rotates, and No.1 sprocket wheel 65 drives drive shaft 61 to rotate by the connection of key 62, and then realizes the No.1 in drive shaft 61
Cylindrical projection 611 and No. two cylindrical projections 612 rotate, and because No.1 cylindrical projection 611 is slided in No.1 rectangle sliding slot 45,
No. two cylindrical projections 612 are slided in No. two rectangle sliding slots 54, and then realize upper slide 4 and the opposite sliding of lower skateboard 5, Jin Ershi
The top that combustion adjuvant is endlessly supplied to support plate 3 is showed, in the process, the rotation of drive shaft 61 drives the No.1 bullet of lower section
Spring 63 rotates, and the lower end of No.1 spring 63 is slided on the inclined-plane of wedge block 64, when the lower end of No.1 spring 63 slides into inclined-plane
Highest point after there is primary vibration, therefore realize and upper slide 4 and lower skateboard 5 shaken, and then support plate 3 is pushed to become
Shape is shaken, and then comburant is driven to shake up and down, and then it is more abundant so that comburant is burnt, and improves efficiency of combustion and burning
Quality；During motor 73 rotates, the shaft of the slow pushing motor 73 of cylinder 74 is moved up and down, and then drives No. two chains
Wheel 66 moves up and down, and No. two sprocket wheels 66 drive No.1 sprocket wheel 65 to slide up and down along key 62 by chain 67, therefore chain 67 is realized
Discontinuity is invaded not in coolant liquid, both ensure that the temperature of chain 67 will not be too high, guaranteed chain 67 and sealing sliding block
Sealing effect between 71 reduces the outflow of coolant liquid.
In use, drive module 6 drives upper slide 4 and lower skateboard 5 to horizontally slip relatively, and then realize upper slide 4 under
The side wall for the extruding furnace body 1 that slide plate 5 alternates, and then the cavity between upper slide 4 and lower skateboard 5 and side wall is constantly squeezed
Pressure, when 5 side of lower skateboard squeezes the side wall of furnace body 1, upper slide 4 is the side wall far from furnace body 1,5 side of lower skateboard it is fire-retardant
Agent is extruded, and then pushes No. two swinging support doors 53, and combustion adjuvant enters rectangle not through slot 51, while No. two swinging support doors 53
No. three oscillating decks 52 are propped up by the chamfering on upper surface, so fire retardant by the cylindrical hole on No. three oscillating decks 52 to
Upper extruding, and because upper slide 4 is the side wall far from furnace body 1, so that No.1 swinging support door 44 will not squeeze No.1 swing
Plate 43 and No. two oscillating decks 42, therefore No.1 oscillating deck 43 and No. two oscillating decks 42 are logical to No. two rectangles under the action of torsional spring power
Side oscillation in slot 41, therefore fire retardant can be directly through No. two rectangular straight slot 41, and then pass through the No.1 rectangle in support plate 3
Through slot 31 eventually arrives at the top of support plate 3, burns to comburant；When upper slide 4 squeezes the side wall of furnace body 1, upper cunning
The fire retardant of 4 side of plate is extruded, and fire retardant pushes No.1 swinging support door 44, and combustion adjuvant enters No. two rectangular straight slot 41, together
When No.1 swinging support door 44 No.1 oscillating deck 43 is propped up by the chamfering on upper surface, and then fire retardant passes through No.1 and swings
Cylindrical hole on plate 43 is upward, and then passes through the No.1 rectangular straight slot 31 in support plate 3, eventually arrives at the upper of support plate 3
Side, burns to comburant；And then realize that combustion adjuvant is constantly sprayed in the left and right sides of support plate 3 upwards, therefore effect of burning
Rate is high, and the on-off control of whole device is realized by mechanical structure, therefore high reliablity, and then ensure that the burning product of device
Matter.
Wherein, motor 73 drives No. two sprocket wheels 66 to rotate, and No. two sprocket wheels 66 drive No.1 sprocket wheel 65 to rotate by chain 67,
No.1 sprocket wheel 65 drives drive shaft 61 to rotate by the connection of key 62, and then realizes 611 He of No.1 cylindrical projection in drive shaft 61
No. two cylindrical projections 612 rotate, and because No.1 cylindrical projection 611 is slided in No.1 rectangle sliding slot 45, No. two cylindrical projections
612 slide in No. two rectangle sliding slots 54, and then realize upper slide 4 and the opposite sliding of lower skateboard 5, and then realize combustion adjuvant
It is endlessly supplied to the top of support plate 3, in the process, the rotation of drive shaft 61 drives the No.1 spring 63 of lower section to rotate, and one
The lower end of number spring 63 is slided on the inclined-plane of wedge block 64, is gone out after the lower end of No.1 spring 63 slides into the highest point on inclined-plane
Primary vibration is showed, therefore has realized and upper slide 4 and lower skateboard 5 are shaken, and then pushed the deformation shake of support plate 3, in turn
Comburant is driven to shake up and down, and then it is more abundant so that comburant is burnt, and improves efficiency of combustion and combustion quality；In motor
During 73 rotations, the shaft of the slow pushing motor 73 of cylinder 74 is moved up and down, and then is driven and moved down on No. two sprocket wheels 66
Dynamic, No. two sprocket wheels 66 drive No.1 sprocket wheel 65 to slide up and down along key 62 by chain 67, therefore chain 67 realizes invading for discontinuity
Not in coolant liquid, it both ensure that the temperature of chain 67 will not be too high, it is guaranteed close between chain 67 and sealing sliding block 71
Effect is sealed, the outflow of coolant liquid is reduced.
