The working principle and the using flow of the invention are as follows:
the operator connects the material injection pipe 12 to the corresponding dry-mixed mortar feeding device area, and meanwhile the air supply pipe 23 is fixedly communicated with the outside hot air;
after all the materials are ready, the main control device 13 is manually controlled to realize the driving work of the motor 7, at the moment, dry-mixed mortar materials are continuously conveyed into the material guiding cover 6 and the stirring barrel 1 through the material injection pipe 12, and the other end of the material injection pipe 12 is closed after the material injection pipe 12 is conveyed and closed, so that the subsequent waste of hot gas is avoided; the whole stirring device 14 rotates synchronously under the control of the rotation of the motor 7, the materials which are relatively piled up originally are rapidly dispersed around the whole stirring barrel 1, and finally rapidly enter the top of the blanking plate 16 with the help of the interval between the stirring device 14, the inner shell 17 and the stirring barrel 1; as the materials are gradually accumulated, the screw disc 142 starts to screw the materials below upwards, in the process, the materials are mixed and stirred for the first time, and as the height of the materials is continuously increased, when the materials reach the highest value, the materials fall into the inner side or the outer side of the top of the inner shell 17 due to the influence of losing the constraint of the inner shell 17, the materials on the inner side return to the screw disc 142 structure again due to the influence of slope design, and wait for the next pushing, and the materials on the outer side rapidly fall into the interval between the stirring barrel 1 and the inner shell 17 to move downwards due to the slope guidance and the pushing of the lateral claw 145 and the scraping blade 146; on the other hand, the rotation of the motor 7 drives the driving gear 8, the driven gear 9 and the cam 10, the cam 10 starts to intermittently electrify the spring pressure type switch 11 by virtue of the cam design, once the spring pressure type switch 11 is electrified, the accompanying main control device 13 starts to control the hot air engine 22 and the air supply pipe 23 to supply external hot air, at the moment, the hot air starts to enter the air storage ring 21 and then is quickly supplied to the air injection impact device 18, the hot air enables the inner cylinder 184 and the air passage 185 to separate and work through the air passage 185, when the two are separated to a certain extent, the air is discharged from the air hole 187, and then is supplied to the inside of the mortar material through the air holes of the sealed metal net 20 and the inner shell 17, so that the quick and uniform drying of the inside of the movable mortar is realized, and at the same time, the air injection impact device 18 extends, the lower end of the vibration device 15 is pressed down, then the impact rubber 155 at the lower end impacts the inner shell 17, but because of the intermittence of the air injection impact device 18, once the air supply in the air storage ring 21 stops, the air of the air injection impact device 18 is discharged from the air hole 187 area, the internal pressure is greatly reduced, the elastic component and the counterweight component in the original vibration device 15 are combined with the elastic component of the air injection impact device 18, the impact rubber 155 at the upper end impacts the inner shell 17 quickly because of the violent reset and unbalance, the impact rubber 155 uniformly and stably impacts the bottom surface of the inner shell 17 under the repeated work of the air injection impact device 18, the materials passing through the area can be dried and discharged smoothly, and then enter the bottom of the stirring barrel 1 to enter the next circulation, so that the work is repeated, stopping until the treatment and stirring are finished;
the dry-mixed mortar after the treatment is uniformly stirred at the moment, and the new drying treatment is also carried out in the process, and then the operator only needs to open the blanking plate 16 structure, so that the materials can be uniformly dropped and discharged.
