Fig. 1-7 is please referred to, Fig. 1-7 shows the specific structure of the furnace top distributing gear 200 provided in embodiment.
It include ontology 210, center 220, chute 230, connector from can be seen that the furnace top distributing gear 200 in Fig. 1-7
240 and first dynamic structure 250.
Wherein, center 220 and chute 230 are movably disposed in ontology 210 along preset direction, and chute 230
Discharge end stretch out ontology 210；Chute 230 is located in center 220, and passes through connector 240 and bracket 283 and center
220 connections.
First dynamic structure 250 is for driving chute 230 to fascinate on the axis direction of center 220.
Specifically, the first dynamic structure 250 includes the first power device 251, the first pivoting support 252, sliding sleeve 253, leads
To component 254, lifting set 255 and transmission component 256.
First pivoting support 252 is connect with sliding sleeve 253, the first power device 251 for drive the first pivoting support 252 with
And sliding sleeve 253 is rotated around the axis of center 220；
Lifting set 255 and sliding sleeve 253 are sequentially sleeved at outside center 220, and guidance set 254 is located at sliding sleeve 253 and lifting
Between set 255, it is used in axis rotation of the sliding sleeve 253 around center 220, axis of the guidance lifting set 255 along center 220
The movement of line direction；Transmission component 256 is located between lifting set 255 and center 220, and be sequentially connected connector 240 and lifting
Set 255, with when lifting set 255 is moved along the axis direction of center 220, the axis with follower link 240 around its own turns
It is dynamic, to drive chute 230 to fascinate on the axis direction of center 220.
As can be seen that the furnace top distributing gear 200 drives chute 230 to exist by the first dynamic structure 250 in from the discussion above
It fascinates on the axis direction of center 220, so that the furnace top distributing gear 200 can realize fan-shaped cloth, fixed point cloth, monocycle
A variety of distributing modes such as cloth, polycyclic distributing, straight line cloth and curve cloth.Specifically, to realize fascinating for chute 230, it should
Furnace top distributing gear 200 drives the first pivoting support 252 around the axis of center 220 using by the first power device 251
Rotation, since the first pivoting support 252 connect with sliding sleeve 253, therefore the first pivoting support 252 rotate while, sliding sleeve 253 and
First pivoting support 252 rotates synchronously.Further, it is provided with guidance set 254 between sliding sleeve 253 and lifting set 255, when
When sliding sleeve 253 and the first pivoting support 252 rotate synchronously under the driving effect by the first power device 251, in guidance set 254

When two-revolution 262 rotation of bearing, center 220 can be driven to rotate synchronously.Since chute 230 passes through connector 240 and center
220 connection of set, therefore when center 220 rotates, chute 230 and center 220 rotate synchronously.
To sum up, Fig. 1-7 is please referred to, it can be seen from the above content that being able to drive chute 230 by the first dynamic structure 250
It fascinates on the axis direction of center 220, chute 230 is able to drive around the axis of center 220 by the second dynamic structure 260
Line rotation, as a result, chute 230 can be rotated and be fascinated around the axis of center 220, and compound in two kinds of motion modes
In the case where, it can make the furnace top distributing gear 200 that can realize fan-shaped cloth, fixed point cloth, monocycle cloth, polycyclic distributing, straight
A variety of distributing modes such as line cloth and curve cloth.
It should be noted that in the present embodiment, please referring to Fig. 1-3, which further includes the first sender dress
271 and second signal transmitter 272 are set, the first signal transmitter 271 and the second signal transmitter 272 are respectively used to and the first dynamic structure
250 and second dynamic structure 260 be electrically connected, and the first signal transmitter 271 and the second signal transmitter 272 pass through encoder sending
Signal is controlled to PLC system with the movement to the first power device 251 and the second power device 261, thus to furnace roof cloth
The technique of glassware 200 carries out chain control.
First power device 251 include be located at ontology 210 outside, and the motor 2511 being connect with the case lid of ontology 210 211 with
And speed reducer 2512, in order to repair and maintenance.Similarly, the second power device 261 is also including being located at outside ontology 210, and and ontology
The motor 2511 and speed reducer 2512 that 210 case lid 211 connects.
In addition, as can be seen that such chute 230 fascinates, mode can simplify compared with prior art through the above
Structure inside furnace top distributing gear 200 reduces the tie point and number of aperture of internal structure, to pass through the excellent of internal structure
Change, the leakproofness of furnace top distributing gear 200 can be further increased, the loss of internal structure in the process of running is reduced, to drop
The cost that low-dimensional is repaired, and extend the service life of the furnace top distributing gear 200.
Further, referring to figure 2. -6, when guidance set 254 is arranged, in the present embodiment, guidance set 254 includes
The sliding slot 2541 that is arranged on sliding sleeve 253, the slideway 2542 being arranged on 210 inner wall of ontology and setting are on lifting set 255
The first guide wheel 2543 and the second guide wheel 2544, sliding slot 2541 can be the multiple skewed slots being arranged on sliding sleeve 253.
Wherein, the first guide wheel 2543 is used to cooperate with sliding slot 2541, when sliding sleeve 253 rotates, to drive 255 fortune of lifting set
It is dynamic；Second guide wheel 2544 is used to cooperate with slideway 2542, to limit lifting set 255 along center in lifting 255 movement of set
220 axis direction vertical motion.
It should be noted that guidance set 254 may include multiple to improve the stability of the precision of guiding and guiding
Sliding slot 2541, multiple slideways 2542, multiple first guide wheels 2543 and multiple second guide wheels 2544；And the first guide wheel 2543 with
Sliding slot 2541 and the second guide wheel 2544 are corresponded with slideway 2542 to be cooperated, can be in addition, when guidance set 254 is arranged
Interval setting sliding slot 2541 and slideway 2542, so that the first guide wheel 2543 cooperated respectively with sliding slot 2541 and slideway 2542
It should also be as being spaced on lifting set 255 with the second guide wheel 2544 and be arranged.And in the present embodiment, there are four sliding for the configuration of sliding sleeve 253
