s3, then, a material containing dry sand or dry powder is lifted to a feeding port above the top of the dry sand cabin body 5 by using a lifter, and then the material is poured into the feeding port, so that the material moves to the inside of the dry sand cabin body 5 from a high position in a free falling mode, when the material is impacted from top to bottom, the material enters the discharge hopper 502 and then collides with the surface of the first rubber plate 203, then the impact quantity of the material during collision is weakened through the buffering of the first rubber plate 203, and further the ejection height of the material is reduced, so that large particles and small particles in the material cannot be separated due to higher lifting height, and further the occurrence of segregation phenomenon is reduced, in addition, the material on the surface of the anti-segregation inverted cone 2 falls to the surface of the replacement inverted cone 6 through the leakage hole 201 along the inclined surface, then moves downwards along the gap between the replacement inverted cone 6 and the discharge hopper 502, when the replacement inverted cone 6 and the anti-segregation cone 2 impact occur, the arrangement of the second rubber plate 204 and the rubber plate can play the same weakening effect as the first rubber plate 203, so that the large particles and the small particles in the material can be completely mixed together;

s4, in the process, when the material passes through the long rod 1001, if large particles and small particles are uniformly mixed, when the material is impacted and passes through the long rod 1001, the gravity extrusion effect on the surface of the pressure sensor 1003 is in a uniformly distributed state, at the moment, the material passing through the anti-segregation inverted cone 2 and the replacement inverted cone 6 is in a uniformly mixed state, if the material is still subjected to the treatment of the anti-segregation inverted cone 2 and the replacement inverted cone 6, the particles are clearly separated, at the moment, when the material passes through the long rod 1001, the difference between the impact action area of the large particles and the impact action area of the small particles and the action force makes the surface stress of the strip-shaped pressure sensor 1003 uneven and the like, at the moment, the alarm 12 gives an alarm prompt outwards, nearby operators timely close the control valve at the tail end of the discharge hopper 502 to stop bagging operation of the dry powder mortar, and further realize quality control of the dry powder mortar in the bagging process;

s5, after the bagging-off, open switch door 503, pulling pull ring 704, make two sets of pressing pieces 703 be close to each other, make pressing pieces 703 break away from the inside of recess 801, extract the inside of channel-section steel 8 with sliding block 701 afterwards, make connecting module 7 and the inside split of replacement back taper 6 from preventing segregation back taper 2, later take off couple 304 from the surface of horizontal pole 501, will prevent segregation back taper 2 and take out the inside back of hopper 502, operating personnel climbs to the top of dry sand storehouse body 5 through cat ladder 9, carry out corresponding clearance processing to the top surface of dry sand storehouse body 5.

The working principle is as follows: now according to the height of the dry sand bin body 5, the effective hanging length of the connecting hanging rope 3 is adjusted, then the anti-segregation inverted cone 2 is hung on the surface of the cross rod 501 through the hook 304, the installation is convenient, then the material is lifted to the position above a feeding port at the top of the dry sand bin body 5 through the hoister, and then the material is poured into the dry sand bin body 5 to perform free falling motion;

through the matching of the first rubber plate 203, the second rubber plate 204 and the leak hole 201, the impulse of the material impacting on the surface of the anti-segregation inverted cone 2 can be effectively reduced, and the segregation phenomenon of the material in the moving and conveying process is further reduced, so that the device can ensure that the large and small particles of powder and dry sand are in a uniform state when the dry powder mortar is bagged;

in addition, at the bagging-off in-process, carry out homogeneity analysis through display panel 11 to pressure sensors 1003's stress surface to judge whether there is great particle separation phenomenon through the material of preventing after segregation back taper 2 handles, and then in time terminate the bagging-off processing after alarm 12 sends the warning suggestion, avoid dry powder mortar to bag under the uneven condition of large granule and tiny particle mixture and sell, realize the quality management and control of bagging-off in-process and handle.
