[0026] Example 1

[0027] like Figure 1 and Figure 2 As shown,

[0028] An automatic loading and delivery system for high-titanium blast furnace slag building aggregates includes a silo 3, a discharge assembly 5 arranged below the silo 3, a metering and weighing assembly 8 located on both sides below the silo 3, and a PLC control system. The PLC control system adopts a PLC central control machine or a DCS central control machine.

[0029] A confirmation rod 10 is provided in front of the vehicle entrance of the metering and weighing component 8. The driver confirms the entry and exit through the confirmation rod 10, and sends the instruction to the PLC control system. The PLC control system identifies the truck 9 that is about to enter and obtains the material order quantity of the truck 9, and controls the discharge component 5 to discharge the material in a quantitative manner.

[0030] A positioning component 11 and a vehicle type identification component 12 are also fixed below the silo 3 . The positioning component 11 and the vehicle type identification component 12 are respectively connected to the PLC control system for communication. The PLC control system combines the data of the positioning component 11 and the vehicle type identification component 12 . First, the positioning component 11 is divided into front and rear positioning. The front positioning mainly determines the position of the front and rear baffles of the car body. When the front baffle is blocked by a tarpaulin, it can effectively avoid unloading from the discharge port A. The rear detection component mainly determines whether the verification position of the vehicle rear baffle is consistent with the measurement of the vehicle model identification component 12, and at the same time determines whether the rear compartment is closed; second, the vehicle model identification component 12 divides 6 areas through 7 light sensors distributed on the channel. After the vehicle enters, the blocked part is the truck compartment, and the compartment size is obtained through the blocked part; third, combined with the video surveillance on the top of the vehicle, the simulation molding inside the computer is referenced with the landmark; fourth, through the entry of the vehicle license plate in the early stage, the number of vehicle axles is generated in the system, the vehicle length information is determined, and the vehicle information is identified. The truck size is accurately determined by the above identification and judgment method, and then the discharge amount is obtained. It is automatically matched with the discharge, and the discharge port A, B, C, D, E, F is automatically selected to carry out the subsequent discharge and loading work.

[0031] The vehicle type identification component 12 and the positioning component 11 are used to accurately identify the vehicle position, cargo box length, and loading height information. After the communication information is processed, the material discharge component 5 is used to quantitatively discharge the materials in the silo 3. The weighing component 8 is used to weigh the materials discharged into the truck 9, and the discharge is stopped when the specified weight is reached. In this process, the PLC control system automatically calibrates the time schedule of the discharge amount through the accuracy of the discharge once, and the accuracy of the discharge is controlled within 100 kilograms. Through the comparison correction algorithm in the control system, the deviation value of the last discharge is compared with the deviation value of this discharge, and the discharge accuracy value is continuously corrected by continuously initializing the discharge setting value.

[0032] A license plate number recognition rod 13 is provided in front of the weighing component 8, and the license plate number recognition rod 13 is connected to the PLC control system for communication. The license plate number recognition rod 13 is used to recognize the license plate number of the truck entering the bottom of the silo 1, and then transmit the license plate number information to the PLC control system, and the PLC control system recognizes the truck that is about to enter and obtains the material order quantity of the truck to control the discharge component 5 to discharge quantitatively.

[0033] A shooting camera 14 is also fixed on the front and rear side walls of the silo 3. The shooting camera 14 is communicatively connected to the image recognition module of the PLC control system. The loading status of the truck is photographed in real time by the shooting camera 14 and the image information is transmitted to the image recognition module of the PLC control system for recognition, and then analyzed and processed by the PLC control system.

[0034] The silo 3 is used to store high-titanium blast furnace slag building aggregates. The top of the silo is provided with an inclined silo feeding and distributing belt 1 and a horizontal silo feeding and distributing belt 2. The high-titanium blast furnace slag building aggregates can be transported into the silo 3 for storage through the inclined silo feeding and distributing belt 1 and the horizontal silo feeding and distributing belt 2. An exhaust valve 15 is provided at the top of the silo 3.

[0035] The discharge assembly 5 includes a discharge port 4 arranged below the silo 3 and a discharge valve 6 arranged on the discharge port 4, and the discharge valve 6 is connected to the PLC control system. The discharge valve 6 adopts a pneumatic jaw discharge valve, and the opening and closing of the discharge valve 6 is controlled by the PLC control system to realize quantitative discharge.

[0036] The metering weighing assembly 8 includes a weighing plate, a support group arranged below the weighing plate, and a weight sensor located below the support group. The weight sensor is connected to the PLC control system for communication. During the discharge process, the weight of the material entering the truck is sensed by the weight sensor, and the weight of the material entering the truck is obtained by subtracting the weight of the truck and the weight of the weighing plate from the total weight. After the weight sensor transmits the signal to the PLC control system, the PLC control system controls the opening of the discharge valve 6 to discharge the material from the silo 3. When the predetermined weight is reached, the PLC control system issues a stop command to the discharge valve 6 to complete the discharge operation. The PLC control system performs a precise test of this discharge. If the discharge amount does not reach the set value, the PLC control system calculates the refilling time and corrects the pre-discharge time.

[0037] In order to facilitate the settlement of fees, a settlement system for billing is also included, and the settlement system is connected to the PLC control system. The settlement system adopts the existing design, and integrates the settlement system with material discharge and weight counting, which greatly improves the overall work efficiency.

[0038] In order to prevent the dust generated during the discharge process from affecting the surrounding working environment, in the present invention, a dust prevention device 7 is provided at the discharge port 4. When the PLC control system issues a discharge instruction, the dust removal spray device is first allowed to work for 3 seconds to ensure that the loading process is environmentally friendly and controllable.

[0039] like Figure 3 As shown in the figure, in this embodiment, the top view of the 10m and 5m platforms of the silo is shown. In this embodiment, the truck channel under the silo is optimized, wherein the left part (I) adopts a double channel design, and the right part (II) adopts a single channel design. Both schemes have application cases. The double channel design is used to increase the bottom discharge area on the 10m platform, and less dead material is formed inside the aggregate silo. Figure 4 As shown, the double channel can increase the effective volume inside the aggregate bin by 34% compared with the single channel.

[0040] like Figure 5As shown, a schematic diagram of the connection relationship between each functional component and the PLC control system in this embodiment is given, and the actions of each functional component in this embodiment are controlled by the PLC control system.

[0041] like Figure 6 As shown, the automatic loading flow chart of this embodiment is given. The automatic loading and delivery system of high-titanium blast furnace slag building aggregate of the present invention has a reliable structure and good performance. Through this system, the loading vehicle makes an appointment according to the front-end appointment procedure, and the license plate number is identified by the license plate number recognition rod to determine the name, quantity, model, etc. of the loaded product, and the obtained information is transmitted to the central control to guide the next step of operation. When the vehicle reaches the designated loading position, the discharge valve suitable for the model is opened according to the model identification. The discharge and metering are carried out simultaneously. When the metering reservation weight is accurately calculated, the discharge valve stops, and the weighing is carried out through the metering weighing component. The weighing information is transmitted to the back end of the PLC control system for settlement, and the settlement operation is carried out through the settlement system. After the settlement is completed, the system indicator light guides the vehicle to leave. The system integrates silo material distribution, vehicle identification, discharge, weighting, and settlement. The whole process realizes unmanned automatic loading, greatly improves the delivery efficiency, accurately loads, and effectively avoids the safety risks of manual loading.
