s3, when the receiving mechanism where the discharging pipe orifice 27 is located is high, the worker starts the electric push rod 20 to enable the electric push rod to extend upwards, the electric push rod extends and generates an upward pushing force on the round rod 17 through the movable sleeve 19, the pushing force is transmitted to the position where the feeding pipe 15 is located through the two groups of long strips 16, so that the bottom of the feeding pipe 15 rotates along the inner wall of the supporting cylinder plate 18 through the round rod 17 installed on the other two groups of long strips 16, the feeding pipe 15 is inclined upwards at one end where the discharging pipe orifice 27 is located, and conversely, when the receiving mechanism is low, the worker adjusts the feeding pipe 15 to be inclined downwards at one end where the discharging pipe orifice 27 is located through the electric push rod 20;

s4, when the worker needs to clean the inner cavity of the hopper body 1, the electric telescopic rod 11 is started to enable the electric telescopic rod to extend upwards, then an upward pushing force is generated on the four groups of connecting rods 12, then the pushing force is transmitted to the position of the annular pressure reducing plate 6 through the feeding pipe 13, the connecting sleeve 8 and the conical pressure reducing cylinder 7, so that the annular pressure reducing plate 6 is gradually far away from the hopper body 1, then the worker applies a rotating force with a set direction to the connecting sleeve 8, so that the connecting sleeve and the threaded ring 14 are gradually separated from each other, then an upward pulling force is applied to the connecting sleeve 8, the annular pressure reducing plate 6 is driven to be far away from the feeding pipe 13, then the screws on the four groups of square plates 29 are taken down, and then an upward pulling force is applied to the conical separating cylinder 28, so that the conical separating cylinder is pulled out along the outer wall of the protecting sleeve 9.

The working principle is as follows: when a worker introduces dry powder mortar materials into the hopper body 1 through the external feeding mechanism through the feeding pipe 13, the dry powder mortar materials can be scattered to the position of the sieving plate 2 along the outer surface of the conical separating cylinder 28 and then fall down along the sieving plate 2, wherein when the dry powder mortar materials pass through the conical separating cylinder 28 and the sieving plate 2, larger bulk impurities contained in the materials can be intercepted above the conical separating cylinder 28 and the sieving plate 2 so as to achieve the effect of filtering granular impurities, meanwhile, in the material introduction process, the conical decompression cylinder 7 and the annular decompression plate 6 are positioned right above the materials, the condition that the top of the hopper body 1 is sprayed or mixed with the materials due to the problem of air pressure in the hopper body 1 can be effectively avoided, and then when the materials are introduced into the feeding pipe 15 from the position of the telescopic pipe 5, the two sets of motors run synchronously, so as to impel the hob 25 to drive the helical blade 26 to rotate towards the set direction, and then transfer the material to the place where the discharging pipe orifice 27 is located to discharge, and simultaneously, before the material is discharged, impel the electric putter 20 to carry out the operation of upwards extending or downwards contracting according to the actual need, so as to adjust the feeding pipe 15 to the inclined state that the end where the discharging pipe orifice 27 is located is upwards or downwards, so that the interval between the discharging pipe orifice 27 and the ground is adapted to the height of the receiving mechanism itself.
