However, as the volume of the material bin increases, the problem of segregation of mortar becomes more pronounced. When the materials are stored in the material bin, the materials fall into the material bin due to different particles and densities of various raw materials, so that the separation phenomenon between the different raw materials can be formed, and the separation degree is in direct proportion to the falling distance of the raw materials; in the material storage process, raw materials with small volume and large density gradually sink along with the time, so that layering phenomenon of the mixed materials is caused, and the layering problem becomes more serious along with the larger diameter of the material bin.
According to the technical scheme, two cones are arranged at the bottom of the tank body, so that in the process of discharging materials from the mortar tank, the center pit is prevented from falling, the uniformity of material mixing is improved, and the segregation phenomenon is reduced. However, when the cone device is used alone, the effect of preventing the material segregation phenomenon is not obvious, and when the size of the material bin is too large, the device cannot solve the material segregation problem possibly happened in the middle and upper parts of the bin body.

(5) the opening and closing degree of the baffle plate (12) can be manually adjusted while the rotation and revolution speeds of the stirring spiral blade (9) are changed, the included angle between the baffle plate (12) and the horizontal line is changed, and when the stirring spiral blade (9) is in S0 gear, the included angle between the baffle plate (12) and the horizontal line is adjusted to be 90 degrees; when the stirring spiral blade (9) is in S1 gear, the included angle between the baffle plate (12) and the horizontal line is adjusted to be 60 degrees; when the stirring spiral blade (9) is in S2 gear, the included angle between the baffle plate (12) and the horizontal line is adjusted to be 45 degrees; when the stirring spiral blade (9) is in S3 gear, the included angle between the baffle plate (12) and the horizontal line is adjusted to be 30 degrees;
(6) after all materials are conveyed to the material bin (1) through the feeding hole (5), the solid flowmeter (16) transmits flow data to the host machine (17), the host machine (17) gives a stop operation instruction to the motor controller (21), and the stirring screw blade (9) returns to S0 gear again to turn off the power supply.
