That is, the present application provides that the feeding assembly 40 controls separately whether material is fed into the first weighing hopper 20 and the second weighing hopper 30.
Exemplary metering control method
Fig. 2 is a schematic flow chart of a metering control method provided by the present application, where the metering control method is applied to the material metering device shown in fig. 1, where the metering control method includes the following steps:
step S10: under the condition that the first discharge valve 92 is closed, the feeding assembly 40 is controlled to convey materials to the first weighing hopper 20, and materials in the first weighing hopper 20 are metered through the first weighing hopper 20;
the first discharge valve 92 is closed and the feed assembly 40 is controlled to input material into the first weighing hopper 20 while the first weighing hopper 20 meters the material input into the first weighing hopper 20.
Step S20: when the metering value of the material in the first metering hopper 20 reaches a first metering target value, controlling the feeding assembly 40 to stop conveying the material to the first metering hopper 20;
since the flow cross section of the first discharge pipe 90 is greater than that of the second discharge pipe 91, the first weighing hopper 20 can be used for roughly weighing the materials, that is, step S10 can be actually: the first weighing hopper 20 roughly weighs the material input into the first weighing hopper 20. At this time, the first metering target value in step S20 may be a rough-symmetric metering target value.
Specifically, the reaching of "when the metered value of the material in the first weighing hopper 20 reaches the first metering target value" may be greater than or equal to, that is, "when the metered value of the material in the first weighing hopper 20 reaches the first metering target value" may actually be: "when the metering value of the material in the first weighing hopper 20 is greater than or equal to the first metering target value".
When the material metering value in the first weighing hopper 20 is greater than or equal to the first metering target value, which indicates that the first metering process in the material metering process is finished, the feeding assembly 40 is controlled to stop feeding the material to the first weighing hopper 20.
Step S30: under the condition that the second discharge valve 93 is closed, the feeding assembly 40 is controlled to convey materials into the second weighing hopper 30, and the materials in the second weighing hopper 30 are weighed through the second weighing hopper 30;

Step S40: when the measured value of the material in the second weighing hopper 30 reaches the second measured target value, the feeding assembly 40 is controlled to stop feeding the material to the second weighing hopper 30.
Because the flow cross section of the first discharge pipe 90 is greater than that of the second discharge pipe 91, the second weighing hopper 30 can be used for precisely weighing the materials, that is, the step S30 can be actually: the second weighing hopper 30 precisely weighs the material input into the second weighing hopper 30. At this time, the second metering target value in step S40 may be the fine metering target value.
Specifically, the reaching of "when the metered value of the material in the second weighing hopper 30 reaches the second metering target value" may be greater than or equal to, that is, "when the metered value of the material in the second weighing hopper 30 reaches the second metering target value" may actually be: "when the measured value of the material in the second measuring hopper 30 is greater than or equal to the second target measurement value".
When the material metering value in the second weighing hopper 30 is greater than or equal to the second metering target value, which indicates that the second metering process in the material metering process is finished, the feeding assembly 40 is controlled to stop feeding the material to the second weighing hopper 30.
Through the steps S10-S40, the whole process of material metering is completed, namely the feeding assembly 40 is controlled to convey materials into the two weighing hoppers respectively, the rough weighing metering and the fine weighing metering of the materials are completed through the two weighing hoppers respectively, and the overflowing section of the first discharging pipe 90 is larger than the overflowing section of the second discharging pipe 91, so that the rough weighing quick feeding and the fine weighing slow feeding can be realized, the impact of the materials on the second weighing hopper 30 in the fine weighing process is reduced, the metering precision of the materials is improved, and the rough weighing metering and the fine weighing metering are independently performed without mutual influence, so that the discharging after rough weighing can be performed while the fine weighing is performed, or the rough weighing metering of the lower tray material can be performed while the discharging after the fine weighing is performed, and the metering efficiency is improved.
In one possible implementation, as shown in fig. 1, the feeding assembly 40 in the material metering device includes: a first feeding pipe 41, wherein the first feeding pipe 41 is communicated with the feeding hole of the first weighing hopper 20; a second feeding pipe 43, wherein the second feeding pipe 43 is communicated with the feeding hole of the second metering hopper 30; a first feed valve 42 provided on the first feed pipe 41; and a second feed valve 44 provided on the second feed pipe 43.
As shown in fig. 3, the step S10 of "controlling the feeding assembly 40 to feed the material to the first weighing hopper 20" may specifically include the following steps:
step S11: controlling the first feeding valve 42 to be opened and the second feeding valve 44 to be closed to feed the material to the first weighing hopper 20 through the first feeding pipe 41;

step S11: and calculating a first metering target value based on the preset total target value and the preset metering value of the material.

In one possible implementation, as shown in fig. 5, before step S30 (the material in the second weighing hopper 30 is weighed by the second weighing hopper 30), the metering control method further includes:
step S33: acquiring an actual metering value of a related material related to the material;
related materials refer to materials that are mixed together to form a new material. For example, when the material includes asphalt, the asphalt can be combined with white material (white material refers to aggregate and powder in the mix proportion of the asphalt mixture) to form an asphalt mixture, and then the white material is the associated material of the asphalt. When the asphalt and the white material are stirred and mixed to form the asphalt mixture, the asphalt and the white material are respectively measured.

In the process of material metering, the second metering target value of the material is corrected in real time according to the actual metering value of the associated material, so that the metering accuracy of the material is improved.
In a possible implementation manner, as shown in fig. 6, the step S34 (calculating the second metering target value based on the actual metering value of the associated material) specifically includes the following steps:
step S341: calculating an actual total target value of the materials based on the actual metering value of the associated materials and a preset proportion between the materials and the associated materials;
the actual total target value of the material is adjusted in real time through the actual metering value of the material related to the material, so that the second metering target value of the material is adjusted in real time, and the metering precision is improved.
Step S342: acquiring an actual metering value of the first metering hopper 20 to the material in the first metering hopper 20 when the metering value of the material in the first metering hopper 20 reaches a first metering target value, so as to obtain a first actual metering value;
wherein, the first actual metering value of the material is: when the metered value of the material of the first weighing hopper 20 reaches a first target value, the actual metered value of the material in the first weighing hopper 20.
Step S343: a second metering target value is calculated based on the actual total target value and the first actual metering value.
The actual metering value of the material is adjusted in real time through the actual metering value of the material related to the material, and the second metering target value of the material is adjusted in real time according to the actual metering value when the first metering hopper 20 meters the material, so that the metering precision is improved.
In one possible implementation, as shown in fig. 7, while the step S20 (when the measured value of the material in the first weighing hopper 20 reaches the first measurement target value, the feeding assembly 40 is controlled to stop feeding the material to the first weighing hopper 20), the measurement control method further includes the following steps:
step S50: the first discharge valve 92 is controlled to be opened so that the materials metered through the first weighing hopper 20 are discharged into the stirring device 13 through the first discharge pipe 90.
When the first metering of the materials is completed, the first discharge valve 92 is opened, the first metered materials are conveyed to the stirring device 13 for stirring, and the feeding time is shortened.
In a possible implementation manner, as shown in fig. 8, step S50 may be further provided after step S20 (when the measured value of the material in the first measuring hopper 20 reaches the first measured target value, the feeding assembly 40 is controlled to stop feeding the material to the first measuring hopper 20), in which case step S50 may be performed simultaneously with step S30 (when the second discharging valve 93 is closed, the feeding assembly 40 is controlled to feed the material into the second measuring hopper 30, and the material in the second measuring hopper 30 is measured by the second measuring hopper 30), that is, when the material is measured for the second time, the first discharging valve 92 is opened, and the material measured for the first time is fed to the stirring device 13 to be stirred, so as to shorten the feeding time.
In one possible implementation, as shown in fig. 9, while the metering control method at step S40 (when the metering value of the material in the second weighing hopper 30 reaches the second metering target value, the feeding assembly 40 is controlled to stop feeding the material to the second weighing hopper 30), the metering control method further includes the following steps:
step S60: the second discharge valve 93 is controlled to open, and the feeding assembly 40 is controlled to feed the material to the first weighing hopper 20 and to meter the material in the first weighing hopper 20 through the first weighing hopper 20 with the first discharge valve 92 closed.
When carrying out the second measurement of current round of measurement process promptly, open the first measurement in the second round of measurement process promptly to shorten the measurement time of whole material, improved material measurement efficiency.
