[0031] The central processing module is communicatively connected to the preset module, the discharge module, and the detection module. The central processing module determines the discharge speed of each funnel based on the given feed flow rate from the discharge module and the material shape from the preset module, and transmits the discharge speed to the discharge module. The central processing module also receives the flow rate value of the material on the belt conveyor detected by the detection module to determine the actual feed flow rate, and calculates the calibration flow rate of each funnel based on the deviation between the given feed flow rate and the actual feed flow rate.

[0033] The discharge module receives the calibration speed and adjusts the discharge speed of the funnel according to the calibration speed.

[0034] The central processing module of this invention is communicatively connected to the preset module, the discharge module, and the detection module, respectively. The central processing module is used to determine the discharge speed of each funnel based on the feed flow rate of the funnel transmitted from the discharge module and the shape of the material transmitted from the preset module, and transmits the discharge speed to the discharge module. The central processing module is also used to receive the flow rate value of the material on the belt conveyor detected by the detection module to determine the actual feed flow rate, and calculate the calibration flow rate of each funnel based on the deviation between the given feed flow rate and the actual feed flow rate. The calibration module is communicatively connected to the central processing module and the discharge module, respectively. The calibration module is used to receive the calibration flow rate transmitted from the central processing module and calculate the calibration speed of the funnel based on the calibration flow rate, and transmit the calibration speed to the discharge module. The discharge module receives the calibration speed and adjusts the discharge speed of the funnel according to the calibration speed. This invention can monitor the material feeding situation in a timely manner, which greatly reduces the workload of the operator and avoids phenomena such as empty hoppers or overflowing hoppers. It improves the stability and efficiency of feeding, realizes automated feeding, and promotes the development of automated production lines for tippers.

[0035] In the above scheme, as a preferred, the preset module records the material form including 0-10mm material, 10mm-50mm granular material, 50mm-80mm granular material, and 80mm or more material. This is only one specific material distribution method of the present application in practical application, and a more scientific material division standard can also be learned according to actual needs or through AI.

[0036] In the above scheme, as a preferred, the discharge speed of the funnel is negatively related to the particle size of the material in the funnel. The discharge speed of the material with larger particles is lower, avoiding damage to the belt.

Finally, the new given feeding flow and the new discharge speed are transmitted to the discharge module. By presetting the discharge speed of each material, the damage to the belt and other equipment caused by too fast material discharge is further avoided under the premise of considering the work efficiency. The preset discharge speed range can be determined according to the actual use of the belt.
