Description

Technical Field

[0001] This utility model belongs to the technical field of concrete processing equipment, specifically relating to a multi-functional metering hopper for concrete production batching. Background Technology

[0002] Concrete metering hoppers are mainly used in concrete mixing plants to measure various raw materials (such as cement, aggregates, and mineral admixtures) used in concrete production. They are an important component of mechanized concrete production. Existing concrete metering hoppers are mostly composed of a suspended weighing device, a hopper body, and an automatic unloading gate. However, during unloading, there may be a lot of dust in the concrete batching. The dust will be dispersed into the air under the impact of continuous discharge, causing air pollution and adversely affecting the health of workers and the surrounding ecological environment. Therefore, further improvements should be made to the existing concrete metering hopper design to solve the above-mentioned technical problems. To this end, this application provides a multi-functional metering hopper for concrete production batching. Utility Model Content

[0003] The purpose of this utility model is to provide a multi-functional metering hopper for concrete production batching in order to solve the above-mentioned problems, and to address the shortcomings of the existing technology.

[0004] This utility model achieves the above objectives through the following technical solutions:

[0005] A multi-functional metering hopper for concrete production batching includes a hopper body with a discharge port at the bottom, a discharge assembly on the hopper body, a dust suppression spray assembly on the outer periphery of the discharge port, a cleaning assembly on the hopper body for cleaning the discharge assembly, and a controller for controlling the operation of the discharge assembly, the dust suppression spray assembly, and the cleaning assembly.

[0006] As a further optimization of this utility model, the unloading assembly includes a connecting plate symmetrically rotatably connected to the bucket body, a sealing plate for connecting the two connecting plates and sealing the discharge port, and a telescopic component 1 provided on the side wall of the bucket body for pushing the sealing plate to rotate relative to the bucket body. The telescopic component 1 is rotatably connected to the bucket body and the sealing plate respectively through a hinge seat, and the signal input terminal of the telescopic component 1 is connected to the signal output terminal of the controller.

[0007] As a further optimization of this utility model, the dust suppression spraying assembly includes a conveying pipe surrounding the outer wall of the hopper, several atomizing nozzles located at the bottom of the conveying pipe, and a conveying pump connected to the input end of the conveying pipe. The conveying pipe is located above the discharge port of the hopper and between two connecting plates and a sealing plate. The signal input end of the conveying pump is connected to the signal output end of the controller.

[0008] As a further optimization of this utility model, the dust suppression spraying assembly also includes at least one obstruction detector installed on the conveying pipeline. The obstruction detector is used to detect whether the sealing plate is obstructing and sealing the bottom of the hopper outlet. The signal output terminal of the obstruction detector is connected to the signal input terminal of the controller.

[0009] As a further optimization of this utility model, the cleaning component includes a second telescopic member disposed on the side wall of the bucket body and parallel to the output end of the first telescopic member, and a brush head connected to the telescopic end of the second telescopic member. The brush head is used to contact the inner side wall of the sealing plate to clean the concrete material on the sealing plate. The signal input end of the second telescopic member is connected to the signal output end of the controller.

[0010] As a further optimization of this utility model, the second telescopic member is provided with a moving groove for the telescopic end of the first telescopic member to move.

[0011] As a further optimization of this utility model, a suspended weighing device is connected to the top of the bucket body, and the signal output terminal of the suspended weighing device is connected to the signal input terminal of the controller.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1) This utility model uses a suspended weighing device to weigh the concrete batching material inside the hopper. When the weight reaches the set target range, the telescopic component drives the sealing plate to rotate to the side of the hopper, so that the discharge port of the hopper is not blocked or sealed to allow the concrete batching material to be unloaded. At the same time, a dust suppression component sprays mist water around the outer ring of the discharge port of the hopper to reduce dust floating. At the same time, a cleaning component cleans the inner wall of the sealing plate to reduce the amount of concrete batching material adhering to the inner wall of the sealing plate. The weighing hopper of this application integrates multiple functions and is more convenient to use.

[0014] 2) The concrete mix swept down by the brush head falls down the slope of the sealing plate and is then mixed with the unloaded concrete mix inside the hopper and transported to the subsequent processing equipment by the conveyor belt, which can make full use of the material.

[0019] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0020] like Figure 1-3 As shown, a multi-functional metering hopper for concrete production batching includes a hopper body 1 with a discharge port at the bottom, a discharge assembly on the hopper body 1, a dust suppression spray assembly on the outer periphery of the discharge port of the hopper body 1, a cleaning assembly on the hopper body 1 for cleaning the discharge assembly, and a controller 12 for controlling the operation of the discharge assembly, the dust suppression spray assembly, and the cleaning assembly.

[0021] Preferably, the unloading assembly includes a connecting plate 2 symmetrically rotatably connected to the bucket body 1, a sealing plate 3 for connecting the two connecting plates 2 and sealing the discharge port, and a telescopic member 4 disposed on the side wall of the bucket body 1 for pushing the sealing plate 3 to rotate relative to the bucket body 1. The telescopic member 4 is rotatably connected to the bucket body 1 and the sealing plate 3 respectively through a hinge seat. The signal input terminal of the telescopic member 4 is connected to the signal output terminal of the controller 12.

[0022] Preferably, the dust suppression spraying assembly includes a conveying pipe 7 surrounding the outer wall of the bucket body 1, a plurality of atomizing nozzles 8 located at the bottom of the conveying pipe 7, and a conveying pump 10 connected to the input end of the conveying pipe 7. The conveying pipe 7 is located above the discharge port of the bucket body 1 and between two connecting plates 2 and a sealing plate 3. The signal input end of the conveying pump 10 is connected to the signal output end of the controller 12.

[0023] Preferably, the dust suppression spraying assembly further includes at least one obstruction detector 9 disposed on the conveying pipe 7. The obstruction detector 9 is used to detect whether the sealing plate 3 is obstructing and sealing the bottom of the discharge port of the hopper 1. The signal output terminal of the obstruction detector 9 is connected to the signal input terminal of the controller 12.

[0024] It should be noted that, in this embodiment, the occlusion detector 9 is either a photoelectric sensor or a pressure sensor.

[0025] Preferably, the cleaning component includes a second telescopic member 5 disposed on the side wall of the bucket body 1 and parallel to the output end of the first telescopic member 4, and a brush head 6 connected to the telescopic end of the second telescopic member 5. The brush head 6 is used to contact the inner side wall of the sealing plate 3 to clean the concrete material on the sealing plate 3. The signal input end of the second telescopic member 5 is connected to the signal output end of the controller 12.

[0026] It should be noted that, in this embodiment, the telescopic component 4 and the telescopic component 5 include, but are not limited to, hydraulic cylinders, and also include electric push rods or pneumatic cylinders.

[0027] Preferably, the telescopic component 2 5 has a pre-reserved moving groove for the telescopic end of the telescopic component 1 4 to move, so that the brush head 6 will not obstruct the movement of the telescopic end of the telescopic component 1 4.

[0028] Preferably, a suspended weighing device 11 is connected to the top of the bucket body 1. The suspended weighing device 11 is a conventional technical means in the prior art, and will not be described in detail here. The signal output terminal of the suspended weighing device 11 is connected to the signal input terminal of the controller 12.

[0029] In use, the weight of the material inside the hopper 1 is weighed by the suspended weighing device 11. When the weight of the material inside the hopper 1 reaches the set target range, the controller 12 controls the telescopic component 4 to work. The telescopic end of the telescopic component 4 retracts its length to drive the sealing plate 3 and the connecting plate 2 to rotate relative to the hopper 1, exposing the discharge port of the hopper 1. The concrete batching material inside the hopper 1 is then conveyed down from the discharge port of the hopper 1. While the sealing plate 3 and the connecting plate 2 are rotating relative to the hopper 1, the obstruction detector 9 detects in real time whether the discharge port of the hopper 1 is in a blocked state. When the obstruction detector 9 detects a signal that the sealing plate 3 is not blocking the bottom of the discharge port of the hopper 1, it sends the signal to the controller 12, which then controls the conveying pump 10 to start. The conveying pump 10 draws water from the water source and delivers it to the conveying pipe 7, which then delivers it to the atomizing nozzle 8. The atomizing nozzle 8 sprays the water onto the falling concrete batching material. The conveying pipe 7 is arranged around the outer wall of the bucket body 1. A mist of water is sprayed around the outer perimeter of the discharge port of the bucket body 1, which can reduce dust floating and reduce dust pollution in the air. When the obstruction detector 9 detects that the sealing plate 3 is not sealed at the bottom of the discharge port of the bucket body 1, it sends the signal to the controller 12. The controller 12 will also control the telescopic component 2 5 to start. The operation of the telescopic component 2 5 will drive the brush head 6 to move relative to the side wall of the bucket body 1. The brush head 6 contacts the inner side wall of the sealing plate 3, thereby cleaning the inside of the sealing plate 3. Under the action of water vapor, concrete material is easily adhered to the inner side wall of the sealing plate 3. Cleaning the sealing plate 3 can reduce the concrete material adhering to the inner side wall of the sealing plate 3. The cleaned concrete material falls down with the slope of the sealing plate 3 and will then be mixed with the concrete material unloaded inside the bucket body 1 and transported to the subsequent processing equipment by the conveyor belt, which can make full use of the material.

[0030] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
