[0016] The main control circuit board 5 is integrated with a central microprocessor, and the central microprocessor is respectively connected to a gyroscope, a communication circuit and a power supply circuit. The gyroscope is used to convert the angular velocity into an electrical signal when it is detected and output to the central microprocessor. The central microprocessor transmits the above electrical signal to the host computer through the communication circuit, and then obtains the rotation angle information through calculation or processing.

[0017] The encoder 6 and the code disc 9 are both high-precision encoders to improve the accuracy of angle and length measurement.

[0018] The main control circuit board 5 is also provided with a storage module for storing metering data and equipment operation status to facilitate subsequent data analysis and equipment maintenance.

[0019] The detailed connection means are well-known in the art. The following mainly introduces the working principle and process. The specific work is as follows.

[0020] A coking shaking feeder metering device is installed on the channel steel on one side of the shaking feeder outlet hopper to keep the code disk 9 in contact with the coal powder; the code disk 9 rotates around the rotating shaft 8 as the coal powder flows and is discharged, and the code disk starts counting, measures the angular displacement, and transmits it to the host computer through the built-in communication module of the encoder 6. The host computer combines the measured angular displacement with the radius to calculate the actual rolling distance, that is, the coal powder feeding length; the change in the thickness of the coal powder in the hopper drives the crank angle detection component 3 and the feeding length metering component 4 to rotate synchronously, and the gyroscope inside the crank angle detection component 3 converts the detected angular velocity into an electrical signal and outputs it to the central microprocessor, and the central microprocessor transmits the above electrical signal to the host computer through the communication circuit, and the host computer calculates the current height of the coal powder in the hopper based on the rotation angle and trigonometric functions.

[0021] Calculation principle:

[0022] The volume of coal powder discharged from a single discharge port = hopper width × coal powder thickness in the hopper × coal powder feeding length

[0023] Wherein: the thickness of the coal powder in the hopper is calculated by the rotation angle measured by the gyroscope and the trigonometric function to obtain the current height of the coal powder in the hopper; the feeding length of the coal powder is calculated by the upper computer by combining the measured angular displacement with the radius to obtain the actual rolling distance.

[0024] And based on the statistical measurement principle, whether the surface is flat has little effect on the result. As long as the mechanical working conditions do not change, the surface fluctuation pattern is stable over a sufficiently long period, and microscopic unevenness does not affect the overall measurement result.

[0025] Therefore, the weight of coal powder discharged from a single discharge port = volume × density.

[0026] The utility model transmits data to a computer in a wireless LORA manner. The computer database can store real-time data for a long time and display the loading status in real time through the analysis function, providing real-time and accurate control basis data for the automatic control of the shaking feeder, and also providing accurate measurement data for the total weight and coal-to-coke ratio control of the coal cakes, ensuring that the processing parameters and quality of each coal cake are consistent, and eliminating the problem of unquantifiable and unstable quality due to manual operation.

[0027] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
