Description

Technical Field

[0001] This utility model relates to the technical field of powder weighing devices, specifically a powder weighing device for concrete processing. Background Technology

[0002] In the concrete processing process, the powder weighing device is one of the key pieces of equipment to ensure the quality of concrete. It is mainly used to accurately measure and control the weight of powder required for concrete production, so as to ensure that the concrete mix proportion is accurate, thereby affecting the strength and performance of the final product.

[0003] Traditional concrete processing powder feeding devices are usually suspended when connected to external conveying pipes, lacking effective sealing measures. When powder is added, it leaks from the connection point during the conveying process, generating a large amount of dust. This dust permeates the surrounding environment, causing pollution. Utility Model Content

[0004] The purpose of this utility model is to provide a powder weighing device for concrete processing, which solves the problem that traditional powder feeding devices for concrete processing are usually suspended when connected to external conveying pipes, lacking effective sealing measures. When powder is added, the powder will leak from the connection point during the conveying process, generating a large amount of dust. This dust permeates the surrounding environment, causing pollution.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a powder weighing device for concrete processing, including a weighing hopper, a fixing frame fixedly installed on the outer surface of the weighing hopper, a feeding pipe fixedly installed on the upper surface of the weighing hopper, a vibration mechanism fixedly installed on the outer surface of the weighing hopper, the vibration end of the vibration mechanism being located on the outer surface of the weighing hopper, a plurality of sliding grooves being formed on the outer surface of the feeding pipe, and a sealing mechanism being provided on the outer surface of the feeding pipe, the sealing end of the sealing mechanism being located at the feeding end of the feeding pipe.

[0006] Furthermore, the sealing mechanism includes a movable tube, which is sleeved on the outer surface of the feeding tube and slidably connected to the slide groove, and a limit plate is fixedly installed on the outer surface of the movable tube.

[0007] Furthermore, an electric push rod is fixedly installed on the upper surface of the feeding tube. The number of electric push rods is fixed to two, and the electric push rods are symmetrically distributed on both sides of the feeding tube. The output end of each electric push rod is fixedly connected to the lower surface of the limiting plate.

[0008] Furthermore, a rubber sealing ring is fixedly installed on the upper surface of the movable tube.

[0009] Furthermore, the vibration mechanism includes a mounting plate, which is fixedly mounted on the outer surface of the weighing hopper, and a protective shell is fixedly mounted on the lower surface of the mounting plate.

[0010] Furthermore, a motor is fixedly mounted on the lower surface of the mounting plate, and an eccentric wheel is fixedly mounted on the output end of the motor. Both the motor and the eccentric wheel are located inside the protective shell.

[0011] This utility model has the following beneficial effects: (1) In this utility model, the external conveying pipe is placed above the feeding pipe. Then, two electric push rods are started. The output end of the electric push rod pushes the limiting plate to move upward. Since the movable pipe is sleeved on the outer surface of the feeding pipe and is slidably connected with the chute, the upward movement of the limiting plate will drive the movable pipe to slide upward along the chute, so that the rubber sealing ring on the movable pipe gradually approaches the feeding end of the external conveying pipe. When the rubber sealing ring and the surrounding area of ​​the external conveying pipe are squeezed and pressed together, a seal can be achieved, which effectively prevents the dust in the powder from spreading and polluting the surrounding environment when feeding.

[0012] (2) When the powder in the symmetrical hopper needs to be vibrated, the motor is started and the output end of the motor drives the eccentric wheel to rotate. Due to the eccentric structure of the eccentric wheel, centrifugal force will be generated during the rotation, which will cause the entire vibration mechanism to vibrate and then transmit to the weighing hopper, thereby causing the powder attached to the weighing hopper to vibrate down, avoiding the powder from adhering to the inner wall of the weighing hopper and causing the discharge to be inaccurate.

[0013] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0017] Please see Figures 1-4 As shown, this utility model is a powder weighing device for concrete processing, including a weighing hopper 1, a fixing frame 2 fixedly installed on the outer surface of the weighing hopper 1, a feeding pipe 4 fixedly installed on the upper surface of the weighing hopper 1, a vibration mechanism 3 fixedly installed on the outer surface of the weighing hopper 1, the vibration end of the vibration mechanism 3 is located on the outer surface of the weighing hopper 1, a plurality of sliding grooves 401 are opened on the outer surface of the feeding pipe 4, and a sealing mechanism 5 is provided on the outer surface of the feeding pipe 4, with the sealing end of the sealing mechanism 5 located at the feeding end of the feeding pipe 4.

[0018] The sealing mechanism 5 includes a movable tube 501, which is sleeved on the outer surface of the feeding tube 4 and slidably connected to the slide groove 401. A limit plate 502 is fixedly installed on the outer surface of the movable tube 501. An electric push rod 503 is fixedly installed on the upper surface of the feeding pipe 4. There are two electric push rods 503, which are symmetrically distributed on both sides of the feeding pipe 4. The output end of the electric push rod 503 is fixedly connected to the lower surface of the limiting plate 502. A rubber sealing ring 504 is fixedly installed on the upper surface of the movable tube 501; Position the external feeding pipe above the feeding pipe 4, then activate the two electric push rods 503. The output end of the electric push rods 503 pushes the limiting plate 502 upward. Since the movable pipe 501 is sleeved on the outer surface of the feeding pipe 4 and slidably connected to the slide groove 401, the upward movement of the limiting plate 502 will drive the movable pipe 501 to slide upward along the slide groove 401, so that the rubber sealing ring 504 on the movable pipe 501 gradually approaches the feeding end of the external feeding pipe. When the rubber sealing ring 504 and the surrounding area of ​​the external feeding pipe are squeezed and pressed together, a seal can be achieved, effectively preventing dust in the powder from spreading and polluting the surrounding environment during feeding.

[0019] The vibration mechanism 3 includes a mounting plate 301, which is fixedly mounted on the outer surface of the weighing hopper 1, and a protective shell 302 is fixedly mounted on the lower surface of the mounting plate 301. A motor 303 is fixedly mounted on the lower surface of the mounting plate 301, and an eccentric wheel 304 is fixedly mounted on the output end of the motor 303. Both the motor 303 and the eccentric wheel 304 are located inside the protective shell 302. When the powder in the symmetrical hopper 1 needs to be vibrated, the motor 303 is started. The output end of the motor 303 drives the eccentric wheel 304 to rotate. Due to the eccentric structure of the eccentric wheel 304, centrifugal force is generated during the rotation, which causes the entire vibration mechanism 3 to vibrate and then transmits it to the weighing hopper 1, thereby causing the powder attached to the weighing hopper 1 to be vibrated down, avoiding the powder from adhering to the inner wall of the weighing hopper 1 and causing inaccurate discharge.

[0020] In use, the external conveying pipe is positioned above the feeding pipe 4, and then the two electric push rods 503 are activated. The output end of the electric push rods 503 pushes the limiting plate 502 to move upward. Since the movable pipe 501 is sleeved on the outer surface of the feeding pipe 4 and is slidably connected to the slide groove 401, the upward movement of the limiting plate 502 will drive the movable pipe 501 to slide upward along the slide groove 401, so that the rubber sealing ring 504 on the movable pipe 501 gradually approaches the feeding end of the external conveying pipe. When the rubber sealing ring 504 and the surrounding area of ​​the external conveying pipe are squeezed and pressed together, a seal can be achieved, effectively preventing the dust in the powder from spreading and polluting the surrounding environment during feeding. When the powder in the symmetrical hopper 1 needs to be vibrated, the motor 303 is started. The output end of the motor 303 drives the eccentric wheel 304 to rotate. Due to the eccentric structure of the eccentric wheel 304, centrifugal force is generated during the rotation, which causes the entire vibration mechanism 3 to vibrate and then transmits it to the weighing hopper 1, thereby causing the powder attached to the weighing hopper 1 to be vibrated down, avoiding the powder from adhering to the inner wall of the weighing hopper 1 and causing inaccurate discharge.
