The stone powder blockage removing hopper of the utility model has the advantages that the vibration space of stone materials is enlarged through the mutual matching of the frame 1, the hopper body 2, the vibrator 3, the elastic air bag 4, the first electromagnetic valve 5 and the controller 6, and the dredging effect is obviously improved compared with the traditional method in which only the vibrator 3 is arranged; and in the process of expanding and contracting the elastic air bag 4, the elastic air bag acts on the stone and enables the stone to flow, so that the flowing time of the stone can be prolonged, and certain effects on preventing the stone from caking and preventing the arch bridge are achieved.

It is worth mentioning that the elastic air bag 4 preferably comprises a longitudinal air bag 41 and a transverse air bag 42, the longitudinal air bags 41 and the transverse air bags 42 are communicated with each other and form uniformly arranged rectangular through holes, correspondingly, the horizontal section of the hopper body 2 is also rectangular, and a gap for passing stone materials is reserved between the elastic air bag 4 and the rectangular through holes. As shown in fig. 4, the stone can pass through the elastic air bag 4 from the rectangular through hole, and the flow rate of the stone passing through the elastic air bag 4 is improved.

ampere meter

61 and 6 electric connection of controller. The stone material leaves from the discharge port 22 and enters the discharging auger 11, when the flow of the stone material entering the discharging auger 11 is stable, the current value detected by the ammeter 61 fluctuates in a certain range, and when no stone material enters the discharging auger 11, the current value detected by the ammeter 61 is reduced to the no-load current value range of the discharging auger 11. When the current value detected by the ammeter 61 is reduced to the no-load current value range and is kept within the set time, the hopper body 2 can be judged to be blocked, the controller 6 can control the elastic air bag 4 and the vibrator 3 to work until the value detected by the ammeter 61 returns to the normal range, and the controller 6 controls the elastic air bag 4 and the vibrator 3 to work and stop working

Of course, the two modes can be selected one by one, or two modes can be selected simultaneously. Choose for use during two kinds of modes simultaneously, the discharge gate 22 of hopper body 2 will be through rubber expansion sleeve and 11 flexible couplings of ejection of compact auger, and pressure sensor 10 only detects hopper body 2 promptly, elasticity gasbag 4 and is used in the total weight of this internal building stones of hopper, and can not detect the weight of ejection of compact auger 11, prevents that the building stones weight in the ejection of compact auger 11 and the weight of tearing open out the material auger 11 from influencing the data that pressure sensor 10 detected, improves and detects the precision. Whether two kinds of modes cooperate and detect simultaneously that hopper body 2 takes place the putty, further improve the reliability that the stifled hopper was dredged to the mountain flour.
