Side view.
As shown in figure 1, the blowing self-locking device of the present invention is provided in the complete machine of discharging device, discharging device is main
It is made up of electric cabinet 8 and the compound spiral arm 9 of blowing, electric cabinet is internally provided with controller and the control compound spiral arm 9 of blowing rotates
Motor.The blowing self-locking device of the present invention is arranged in blowing composite cantilever 9.
As shown in Fig. 2 a kind of compound blowing self-locking device, including blowing spiral arm 1, blowing support shaft 4, air-expanding shaft 2, current collection
Ring 7 and electric cabinet 8, the blowing spiral arm 1 drive air-expanding shaft 2 to carry out blowing, and the both ends difference of the blowing spiral arm 1 is respective
Equipped with cylinder 3, air cylinder connecting rod 11, cylinder slide connecting rod 5 and photoelectric sensor 10, the centre of the blowing spiral arm 1 opens up one
Individual mounting hole, the blowing support shaft 4 are passed through from the mounting hole and fixed by bearing, and the collector ring 7 is set in institute
State in blowing support shaft 4, the blowing support shaft 4 is connected on the electric cabinet 8 by bearing.
Wherein blowing support shaft 4 penetrates blowing mesopore, and support blowing spiral arm 1 rotates；Two cylinders 3 are separately mounted to blowing
In the through hole at two that two of spiral arm 1, cylinder slide connecting rod 5 and air cylinder connecting rod 11 are respectively interposed blowing spiral arm 1, in cylinder
The inner side of slide link 5 is mounted with a photoelectric sensor 10 respectively, and photoelectric sensor 10 is connected to the current collection in blowing support shaft 4
Ring 7, collector ring 7 pass through connection power control system.
Further, the both ends of blowing spiral arm 1 respectively offer a tie rod holes, and the air cylinder connecting rod 11 can pass through institute
Tie rod holes are stated freely stretch.
Further, the photoelectric sensor 10 is photodiode；The controller is programmable logic controller (PLC).
Further, the collector ring 7 carries out signal transmission with the photoelectric sensor 10 and the controller respectively.
Further, the both ends of blowing spiral arm 1 respectively offer a through hole, the cylinder slide connecting rod 5 by with its
The connecting rod set 6 of interference fit is slidably mounted in the through hole.
As shown in figure 3, circumferentially uniform 3 grooves of air-expanding shaft lock portion 2a, connecting rod is covered on the relevant position of inwall axially
Uniform 3 projections, the two locks cooperation during cylinder slide link motion.
As shown in figure 4, when discharging device normal work, the projection of the circumferential groove 12 of air-expanding shaft and connecting rod set inner ring
13 in locking state.
Specific blowing auto-lock process is as follows：
When 3 air inlet of cylinder, the cylinder slide connecting rod 5 drives the connecting rod set 6 to away from the air-expanding shaft 2
Direction is stretched, and the photoelectric sensor 10 is arranged on the close electric cabinet 8 in the direction of extension of the cylinder slide connecting rod 5

When mechanical normal operation, air valve is closed, and cylinder slide connecting rod 5 collapses, and air-expanding shaft 2 is pinned, in the driving of motor
Under, blowing spiral arm 1 drives air-expanding shaft 2 to carry out rotating blowing motion.
When upset is reloaded, air valve is opened, allows the air inlet of cylinder 3, cylinder slide connecting rod 5 is flexed outward, can now removed
Air-expanding shaft 2 reloads.
In order to ensure that the material when upset is reloaded on air-expanding shaft cannot come off and fall down, when cylinder slide connecting rod 5 is to overhanging
When exhibition is to photoelectric sensor 10, photoelectric sensor 10 passes the signal to rapidly collector ring 7, is transmitted signal by collector ring 7
To controller, deenergization shuts down by motor, and now cylinder slide connecting rod 5 stops stretching, extension, and blowing spiral arm 1 also stops turning
It is dynamic, reach self-locking purpose.
The blowing self-locking device of the present invention, passes through the setting of photoelectric sensor and collector ring so that the present apparatus has can be certainly
The dynamic control system stagnated, makes discharging frame be overturn in safe range, does not allow material to fall.It is additionally configured with circuit control system
System, when cylinder charge, cylinder axis can flex outward, and drive cylinder slide connecting rod to flex outward, now cylinder slide connecting rod band
Dynamic connecting rod set departs from air-expanding shaft, is easy to loading and unloading.When cylinder slide connecting rod is extended outwardly to photoelectric sensor, photoelectric sensor
Collector ring can be passed the signal along to, collector ring passes the signal along to controller again, disconnects blowing electric rotating machine, and motor stops fortune
Turn, reach the purpose of self-locking.Avoid and injure operating personnel, play a part of safeguard protection.
The present invention is it will be apparent that specifically there is following several respects relative to prior art possessed advantage：
1st, the present invention controls cylinder slide connecting rod to flex outward by optoelectronic induction automatic control system, makes air-expanding shaft unlikely
In coming off, material will not tumble injury.
2nd, the photoelectric sensor newly installed additional, collector ring, power control system, a complete automatic discharging upset is constituted
Lock control devices, serve safeguard protection effect；
3rd, this invention input is little, easy to operate, positive effect, can protection materials be not damaged, also can protection staff not
It is injured.
Finally it should be noted that：Various embodiments above is merely illustrative of the technical solution of the present invention, rather than its limitations；To the greatest extent
The present invention is described in detail with reference to foregoing embodiments for pipe, it will be understood by those within the art that：Its according to
