[0002] A weighing hopper for a concrete mixing plant is a device specifically designed for continuous or intermittent weighing of bulk materials (such as cement, aggregates, fly ash, etc.) in a concrete mixing plant. It ensures accurate measurement of concrete raw materials before mixing, thereby guaranteeing concrete quality and production efficiency.

[0003] In the production process of a concrete mixing plant, the weighing hopper is a key piece of equipment for accurately weighing concrete raw materials (such as cement, aggregates, and additives). Its accuracy and reliability directly affect the quality of the finished concrete and the production cost. Traditional concrete mixing plant weighing hoppers often leave some concrete or raw materials inside after each weighing. This not only affects the accuracy of subsequent weighings but may also lead to corrosion or blockage of the hopper due to prolonged residue retention, increasing maintenance costs and production safety hazards. Existing flushing mechanisms are mostly fixed in design, with the water flow direction and intensity of the fixed flushing nozzles typically fixed. This may not adequately cover all surfaces of the weighing hopper, thus affecting the accuracy of the hopper for subsequent uses. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-5 This utility model provides a technical solution:

[0028] A metering hopper for a concrete mixing plant equipped with a flushing mechanism includes a metering hopper body 1. Two symmetrically distributed water tanks 8 are fixedly installed on the outer surface of the metering hopper body 1, arranged diagonally. Two flushing columns 7 are provided on each of the four inner walls of the metering hopper body 1. The hopper body also includes:

[0029] The movable rinsing assembly is located on the outer surface of the metering hopper body 1 and there are four sets of it, which are used to drive the corresponding two rinsing columns 7 to rinse the inner wall of the metering hopper body 1.

[0030] The opening and closing assembly, located on the outer surface of the metering hopper body 1, is used to discharge the rinsed water from the side wall. The metering hopper body 1 is in standby mode. The control panel 2 can control the stirring or metering process as needed. The rinsing column 7 is in the initial position and does not rinse the inner wall of the metering hopper body 1. The opening and closing block 15 slides in the limiting groove 16 through the movable column 17 to close the through hole 18 and prevent water or material leakage. The water in the water tank 8 is connected to the rinsing column 7 through the telescopic pipe 12, but rinsing is not started at this time.

[0031] Furthermore, the movable rinsing assembly includes a fixed block 3, a drive motor 4, a gear 5, a rack 6, and a slot 11. The fixed block 3 is fixedly connected to the outer surface of the metering hopper body 1. The outer surface of the fixed block 3 has a slot 11 extending to the inner wall of the metering hopper body 1. The rack 6 is slidably connected inside the slot 11. The rack 6 passes through the slot 11 and is fixedly connected to two rinsing columns 7. The gear 5 is rotatably connected to the outer surface of the fixed block 3. The drive motor 4 is fixedly installed on the top of the fixed block 3. The output end of the drive motor 4 is fixedly connected to the gear 5. The gear 5 meshes with the rack 6. The drive motor 4 drives the gear 5 to rotate. The gear 5 meshes with the rack 6, causing the rack 6 to slide in the slot 11. The movement of the rack 6 causes the two rinsing columns 7 fixedly connected to it to move on the inner wall of the metering hopper body 1 for rinsing.

[0032] Furthermore, a connecting hose 9 is fixedly connected between the two flushing columns 7 located on the same side, and a telescopic pipe 12 is fixedly connected to the outer surface of the water tank 8. The telescopic pipe 12 is fixedly connected to the adjacent flushing column 7, and the two flushing columns 7 located on the same side are connected by the connecting hose 9 to ensure that the two flushing columns 7 work at the same time. The water in the water tank 8 is supplied to the flushing column 7 through the telescopic pipe 12 for flushing operation. The design of the telescopic pipe 12 allows the flushing column 7 to maintain water supply during movement.

[0033] Furthermore, a control plate 2 is movably connected inside the measuring hopper body 1. Pushing the control plate 2 will cause it to enter the measuring hopper body 1, preventing water from entering the conveyor belt during the cleaning process.

[0034] Furthermore, the opening and closing assembly includes a connecting plate 10, an opening and closing block 15, a limiting groove 16, a movable column 17, and a through hole 18. A through hole 18 is provided on one outer surface of the metering hopper body 1. A connecting plate 10 is fixedly connected to the outer surface of the metering hopper body 1. The through hole 18 is located at the center of the connecting plate 10. A plurality of annularly distributed limiting grooves 16 are provided on the outer surface of the connecting plate 10. Movable columns 17 are slidably connected inside the plurality of limiting grooves 16. Opening and closing blocks 15 are fixedly connected to the outer surfaces of the plurality of movable columns 17. Since the movable columns 17 are inside the rotating disk 13 and the opening and closing blocks 15 are fixed on the outer surfaces of the movable columns 17, the rotation of the rotating disk 13 will drive the opening and closing blocks 15 to move within the limiting grooves 16. The movement of the opening and closing blocks 15 causes the originally closed through hole 18 to open, and the water accumulated in the metering hopper body 1 is discharged through the through hole 18.

[0035] Furthermore, a rotating disk 13 is rotatably connected to the outer surface of the connecting plate 10, and multiple movable columns 17 are located inside the rotating disk 13, rotating the rotating disk 13.

[0036] Furthermore, a limiting post 14 is inserted inside the rotating disk 13. The limiting post 14 is inserted inside the rotating disk 13 to fix the position of the rotating disk 13 and prevent it from rotating accidentally.

[0037] Working principle: When workers need to use the concrete mixing plant's metering hopper equipped with a rinsing mechanism, after the metering hopper body 1 completes one metering or mixing cycle and the inner wall needs to be cleaned, first push the control plate 2 to enter the inside of the metering hopper body 1 to prevent water from entering the conveyor belt during the cleaning process. Start the drive motor 4, which drives the gear 5 to rotate. The gear 5 meshes with the rack 6, causing the rack 6 to slide in the slot 11. The movement of the rack 6 drives the two rinsing columns 7, which are fixedly connected to it, to move on the inner wall of the metering hopper body 1 for rinsing. The two rinsing columns 7 located on the same side are connected by a connecting hose 9 to ensure that the two rinsing columns 7 work simultaneously. Water in the water tank 8 is supplied to the rinsing columns 7 through the telescopic pipe 12 for rinsing. The design of the telescopic pipe 12 allows... The flushing column 7 maintains a water supply during movement. After flushing, the water in the metering hopper body 1 needs to be drained. The rotating disk 13 is rotated. Since the movable column 17 is inside the rotating disk 13 and the outer surface of the movable column 17 is fixed with an opening and closing block 15, the rotation of the rotating disk 13 will drive the opening and closing block 15 to move within the limiting groove 16. The movement of the opening and closing block 15 opens the position of the originally closed through hole 18, and the water in the metering hopper body 1 is discharged through the through hole 18. The limiting column 14 is inserted into the rotating disk 13 to fix the position of the rotating disk 13 and prevent it from rotating accidentally. After the drainage is completed, the rotating disk 13 is rotated again to close the through hole 18 with the opening and closing block 15. The drive motor 4 is started in reverse to return the flushing column 7 to the initial position. The metering hopper body 1 enters the standby state and is ready for the next metering or stirring operation.
