Description

Technical Field

[0001] This invention relates to the field of concrete mixing technology, and in particular to an automatic feeding device for a concrete mixing plant. Background Technology

[0002] Automatic feeding equipment for concrete batching plants is a type of equipment specifically designed for concrete batching plants. It aims to automate the feeding and dispensing process of concrete raw materials. This equipment typically consists of a series of components, including a conveying system, a metering system, and a control system.

[0003] The existing automatic feeding equipment for concrete mixing plants generally has the following shortcomings when in use:

[0004] (1) Concrete feeding equipment generates a lot of dust when handling and dumping concrete. This dust may affect the health of operators and cause environmental pollution. In addition to being harmful to personnel health, dust may also reduce the visibility of operations, increase equipment maintenance costs, and damage nearby equipment and structures.

[0005] (2) In concrete feeding equipment, concrete may clog hoppers, conveyor belts or pipes, which may be due to poor concrete fluidity, improper hopper design or improper equipment operation. Concrete blockage will interrupt the construction process, increase maintenance and cleaning costs, and delay the completion time of the project.

[0006] Therefore, it is necessary to design an automatic feeding device for concrete mixing plants to solve the above problems. Summary of the Invention

[0017] As a preferred embodiment of the present invention, the dust collection assembly includes two sealed boxes, two sliding plugs, four air pipes, four one-way valves, a suction pipe, and a dust collection box.

This can improve production efficiency and avoid downtime for maintenance and cleaning time and costs.

[0025] 3. Dust absorption and collection: The dust suction pipe can absorb the dust generated during the material feeding process and discharge the dust into the dust collection box through two sealed boxes, which plays the role of collecting dust. This effectively reduces the impact of dust on the health of operators and the environment, and maintains a clean working site.

[0026] 4. Continuous suction effect: By setting up two sealed boxes, the continuous suction effect of the suction pipe is ensured.

The partition 71 is fixed on the inner wall of the feed hopper 2, the material feeding port 72 is opened on the partition 71, and the rotating plate 73 is rotatably mounted on the bottom surface of the partition 71.

[0041] Referring to the figure, the control component 8 includes two fixed frames 81, a motor 82, a reciprocating screw 83, a guide rod 84, a drive plate 85, and an extrusion rod 86. Both fixed frames 81 are fixed on the concrete mixing equipment 1 and are arranged facing each other. The motor 82 is installed on one of the fixed frames 81. The reciprocating screw 83 is rotatably assembled between the two fixed frames 81, and one end of the reciprocating screw 83 is shaft-connected to the output shaft of the motor 82. The guide rod 84 is fixed between the two fixed frames 81. The drive plate 85 is threaded onto the reciprocating screw 83 and slidably mounted on the guide rod 84. The extrusion rod 86 is fixed to the top of the drive plate 85, and one end of the extrusion rod 86 extends into the interior of the feed hopper 2 and is arranged facing the rotating plate 73. By setting the control component 8, it is easy to realize the intermittent feeding of the feed hopper 2.

[0042] Reference Figure 5 The drive assembly 9 includes a frame 91, a turntable 92, a protrusion 93, a swing frame 94, a rotating shaft 95, two guide bushings 96, a moving rod 97, and several locking teeth 98 and several locking teeth 99.

By setting the drive component 9, it is easy to realize the vibration of the dust suction and the feed hopper 2, and realize the linkage effect.

[0043] Reference Figure 6The dust collection assembly 10 includes two sealed boxes 101, two sliding plugs 102, four air pipes 103, four one-way valves 104, a dust collection pipe 105, and a dust collection box 106. The two sealed boxes 101 are fixed to the concrete mixing equipment 1. The two sliding plugs 102 are respectively slidably connected to the inner surfaces of the two sealed boxes 101, and are respectively fixedly connected to both ends of the moving rod 97. The four air pipes 103 are arranged in pairs and are respectively fixedly connected to the two sealed boxes 101. The four one-way valves 104 are respectively installed on the four air pipes 103.

One of the air pipes 103 on each of the two sealed boxes 101 is connected to the dust suction pipe 105, and the other air pipe 103 on each of the two sealed boxes 101 is connected to the dust collection box 106. By setting up the dust suction component 10, the dust suction pipe 105 can absorb the dust, and the two sealed boxes 101 discharge the dust into the dust collection box 106, thus playing a role in collecting the dust. It is worth mentioning that by setting up the two sealed boxes 101, the dust suction pipe 105 can continuously pump air to ensure the dust absorption effect of the dust suction pipe 105.

[0044] Reference Figure 3 The vibration assembly 11 includes a first conductive sheet 111, a second conductive sheet 112, an outer cylinder 113, a slider 114, a second spring 115, a vibration rod 116, and an electromagnet 117.

The second spring 115 is assembled between the outer cylinder 113 and the slider 114. One end of the vibration rod 116 is fixed on the slider 114, and the other end of the vibration rod 116 extends to the outside of the outer cylinder 113. The electromagnet 117 is installed inside the outer cylinder 113. By setting the vibration assembly 11, the feed hopper 2 can generate a vibration effect to improve the feeding speed of the device.

[0045] Reference Figure 3 The inner surface of the outer cylinder 113 fits against the side of the slider 114 to ensure the stability of the slider 114 during movement.

[0046] Reference Figure 4 The rotating plate 73 is positioned directly opposite the material discharge port 72, so that the rotating plate 73 can block the material discharge port 72.

[0047] Reference Figure 6The two one-way valves 104 located on the same sealed box 101 have opposite flow restriction directions. Specifically, one of the one-way valves 104 restricts the airflow to only enter the sealed box 101, while the other one-way valve 104 restricts the airflow to only flow out of the sealed box 101.

[0048] The specific working principle of this invention is as follows:

[0049] When the automatic feeding equipment for concrete mixing plants proposed in this invention is in use, the operator starts the motor 82. When the motor 82 is running, it can drive the reciprocating screw 83 to rotate. Under the limiting action of the guide rod 84, the rotation of the reciprocating screw 82 can drive the drive plate 85 to move back and forth. The extrusion rod 86 will also move back and forth. When the extrusion rod 86 moves away from the motor 82, the extrusion rod 86 will extrude the rotating plate 73, causing the rotating plate 73 to rotate towards the partition plate 71. When the extrusion rod 86 moves to the limit position, the rotating plate 73 is exactly in contact with the partition plate 71. At this time, the rotating plate 73 can block the discharge port 72. When the extrusion rod 86 moves towards the motor 82, the extrusion rod 86 no longer extrudes the rotating plate 73. At this time, the rotating plate 73 will rotate under the action of gravity and no longer block the discharge port 72.

[0050] When the reciprocating screw 83 rotates, it can also drive the turntable 92 to rotate via the shaft. When the turntable 92 rotates, the protrusion 93 will rotate accordingly and squeeze the slide rail on the swing frame 94, causing the swing frame 94 to swing. With the rotation of the turntable 92, the swing frame 94 will swing continuously. When the swing frame 94 swings, it can drive the moving rod 97 to reciprocate through several meshing teeth 1 98 and several meshing teeth 2 99, so that the moving rod 97 pulls the two sliding plugs 102 to reciprocate within the two sealing boxes 101. Since the two sealing boxes 101 and their related structures are exactly the same, only the specific working principle of one of the sealing boxes 101 will be described in detail here: Due to the two one-way valves 1 on the sealing box 101 The flow restriction directions of 04 are opposite. Specifically, one of the one-way valves 104 restricts the airflow to only enter the sealing box 101, and the other one-way valve 104 restricts the airflow to only flow out of the sealing box 101. So when the sliding plug 101 moves toward one side of the sealing box 101, the sealing box 101 can draw the gas in the suction pipe 105, so that the suction pipe 105 can suck up the dust in the feed hopper 2. When the sliding plug 102 moves toward the other side of the sealing box 101, the sealing box 101 can press the dust-laden airflow into the dust collection box 106, thereby achieving the function of dust suction. In addition, during the movement of the moving rod 97, the two guide bushings 96 guide the movement of the moving rod 97 to ensure the stability of the moving rod 97 during the movement process.

[0051] When turntable 92 rotates, conductive sheet 111 also rotates. During this process, conductive sheet 111 periodically comes into contact with conductive sheet 112. When conductive sheet 111 and conductive sheet 112 are in contact, electromagnet 117 is energized and generates magnetism. At this time, electromagnet 117 attracts slider 114 made of magnetic material, causing slider 114 to move towards the feed hopper 2. Vibrating rod 116 moves accordingly and impacts the feed hopper 2. When conductive sheet 111 and conductive sheet 112 are not in contact, the electromagnet... When magnet 117 is de-energized and loses its magnetism, slider 114 will reset under the action of spring 115, causing vibrating rod 116 to move away from hopper 2. Based on the above process, as turntable 92 rotates, vibrating rod 116 will continuously strike hopper 2, causing hopper 2 to vibrate. During the vibration of hopper 2, slide block 4 and slide rod 5 limit hopper 2 to ensure the stability of hopper 2 during vibration. In addition, spring 6 is also installed between slide block 4 and the corresponding side plate 3 to realize the vibration of hopper 2.

[0052] Based on the above process, when the worker puts concrete into the feed hopper 2, when the rotating plate 73 does not block the discharge port 72, the concrete can fall into the concrete mixing equipment 1 through the discharge port 72. When the rotating plate 73 blocks the discharge port 72, the concrete will temporarily accumulate on the partition plate 71, thereby realizing the function of intermittent feeding. In addition, the vibrating feed hopper 2 can increase the falling speed of the concrete and avoid the phenomenon of concrete blockage in the feed hopper 2. During the feeding process, the dust suction pipe 105 can absorb the dust, and the two sealed boxes 101 discharge the dust into the dust collection box 106, which plays a role in collecting the dust. It is worth mentioning that by setting two sealed boxes 101, the dust suction pipe 105 can continuously pump air to ensure the dust absorption effect of the dust suction pipe 105.

[0053] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
