Abstract
Description
Technical Field
[0001] This utility model relates to the field of concrete production technology, specifically to a vibratory unloading device for an anti-solidification concrete storage hopper. Background Technology
[0002] Concrete is an indispensable building material in construction, and it is widely used in many engineering fields such as buildings, bridges, roads, and water conservancy. During the production, transportation and use of concrete, it is often necessary to use storage hoppers to temporarily store concrete.
[0003] Traditional storage hoppers are usually equipped with a discharge device at the bottom. The discharge device has a simple structure, mainly consisting of the hopper body at the bottom of the storage hopper and a valve at the outlet of the hopper body. When discharging, you only need to open the valve, and the concrete can be discharged from the outlet of the hopper body by its own gravity. However, due to the poor fluidity of concrete, during the discharge, the concrete is prone to stagnation at the outlet of the hopper body for a long time due to poor flow, and gradually solidifies. Over time, this will cause the outlet to narrow or even block the outlet.
[0004] To address this issue, we have designed a vibratory unloading device for anti-solidification concrete storage hoppers. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a vibratory unloading device for an anti-solidification concrete storage hopper, thereby solving the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A vibratory unloading device for an anti-solidification concrete storage hopper includes a storage hopper body, which is composed of an upper cylindrical tube and a lower hopper body connected together. The bottom of the hopper body is provided with an outlet. A horizontal plate is installed on the top of the storage hopper body, and a rotating shaft is rotatably installed on the bottom of the horizontal plate. A stirring blade and a pair of scrapers are installed on the rotating shaft. A first motor is installed on the top of the horizontal plate, and the output shaft of the first motor is connected to the rotating shaft.
[0008] The outer side of the bucket is equipped with three air hammers arranged in a circular array and two symmetrical vertical plates. A baffle is set below the outlet. Connecting plates integrally formed with the baffle are provided on both sides of the baffle. There are connecting shafts on the outer sides of the two connecting plates. The two connecting shafts are rotatably mounted on the two vertical plates respectively. A second motor is installed on one of the vertical plates. The output shaft of the second motor is connected to the connecting shaft on the vertical plate.
[0009] Preferably, the stirring blade is spiral-shaped and located on the inner side of the cylindrical tube and the hopper.
[0010] Preferably, the scraper is spiral-shaped, located inside the outlet, and its side edge contacts the inner wall of the outlet.
[0011] Preferably, both sides of the horizontal plate are equipped with hinged flaps that rotate and cover the top of the storage hopper body. The top of the flaps is provided with a handle.
[0012] Preferably, the main body of the storage hopper is equipped with a bracket for supporting the storage hopper, and a guide chute is installed on the bracket, which is located directly below the outlet.
[0013] Preferably, the discharge port of the guide trough is inclined downwards, and the angle between the guide trough and the horizontal plane is about 15 degrees to 45 degrees.
[0014] Compared with the prior art, this utility model provides a vibratory unloading device for anti-solidification concrete storage hopper, which has the following beneficial effects:
[0015] This anti-solidification concrete storage hopper vibratory unloading device uses a first motor to drive the rotating shaft, which in turn drives the mixing blades and scraper to rotate simultaneously. During unloading, the mixing blades continuously mix the concrete to prevent it from solidifying inside the storage hopper body, while the scraper continuously cleans the concrete at the hopper outlet to prevent it from solidifying due to prolonged stagnation. The storage hopper body is also equipped with an air hammer, which generates vibration to assist in unloading. Attached Figure Description

Detailed Implementation
[0022] 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.
[0023] Example 1
[0024] Please see Figures 1-5 This embodiment proposes a vibratory unloading device for concrete storage hoppers that prevents solidification. Its main components include a storage hopper body 1, a horizontal plate 2, a rotating shaft 3, a stirring blade 4, a scraper 5, a first motor 6, a vertical plate 7, a baffle 8, a second motor 9, an air hammer 10, a flip cover 11, and a support 12. The storage hopper body 1 is welded from a cylindrical cylinder 1-1 and a hopper body 1-2. The bottom of the hopper body 1-2 is provided with an outlet 1-3. The horizontal plate 2 is fixed to the top of the cylindrical cylinder 1-1 of the storage hopper body 1 by bolts or directly welded. The rotating shaft 3 is rotatably installed at the bottom of the horizontal plate 2 through bearings. The stirring blade 4 is spirally welded to the rotating shaft 3. The stirring blade 4 is located inside the cylindrical cylinder 1-1 and the hopper body 1-2. The scraper 5 is also spirally welded to the rotating shaft 3. The scraper 5 is located inside the outlet 1-3. The side edge of the scraper 5 contacts the inner side wall of the outlet 1-3. The first motor 6 is installed on the top of the horizontal plate 2 by bolts. The output shaft of the first motor 6 is connected to the rotating shaft 3 through a coupling. Three air hammers 10 are installed in a ring array on the outside of the hopper body 1-2. Two vertical plates 7 are symmetrically welded to the outside of the hopper body 1-2. The connecting plates 8-1 on both sides of the baffle 8 are integrally formed with the baffle 8.
[0025] The connecting shaft 8-2 is welded to the outside of the connecting plate 8-1 and rotatably mounted on the vertical plate 7 through bearings. The second motor 9 is mounted on one of the vertical plates 7 by bolts. The output shaft of the second motor 9 is connected to the connecting shaft 8-2 on the vertical plate 7 through a coupling. The second motor 9 is a geared motor, which is an integration of a reducer and a motor. The reducer part of the geared motor adopts a worm gear reducer, which has self-locking capability.
[0026] When the second motor 9 stops working, the rotation angle of the baffle 8 is locked, and the baffle 8 will not deflect due to gravity or other external forces. The motor part of the geared motor adopts a servo motor. By precisely controlling the rotation angle of the baffle 8, the opening size of the outlets 1-3 can be adjusted, thereby controlling the concrete unloading speed.
[0027] During material storage, the first motor 6 drives the rotating shaft 3 to rotate, which can stir the concrete through the mixing blade 4 to prevent the concrete from solidifying. During unloading, the second motor 9 drives the baffle 8 to rotate, which can open the outlet 1-3. At the same time, the air hammer 10 works to generate vibration to assist unloading. The first motor 6 drives the rotating shaft 3 to rotate, which can quickly discharge the concrete stuck inside the outlet 1-3 through the scraper 5, avoiding the concrete from solidifying at the outlet 1-3 due to long-term retention.
[0028] Example 2
[0029] Based on Example 2, hinged covers 11 are installed on both sides of the horizontal plate 2. The hinged covers 11 can cover the top of the storage hopper body 1. The top of the hinged covers 11 is equipped with a handle for easy opening and closing. When concrete needs to be added, the hinged covers 11 are opened by the handle and the concrete is poured into the storage hopper body 1. After adding, the hinged covers 11 are closed to prevent debris from entering and to avoid rapid evaporation of moisture in the concrete due to air circulation. The first motor 6 drives the mixing blade 4 to continuously mix the concrete, and the scraper 5 continuously cleans the inner wall of the outlet 1-3 to ensure smooth discharge. When discharge is required, the second motor 9 drives the baffle 8 to rotate and open the outlet 1-3. At the same time, the air hammer 10 works to make the hopper body 1-2 vibrate, accelerating the discharge of concrete from the outlet 1-3.
[0030] Example 3:
[0031] Based on Example 2, a support 12 is welded to the outside of the main body 1 of the storage hopper, and a guide trough 13 is installed on the support 12. The guide trough 13 is located directly below the outlet 1-3. The outlet of the guide trough 13 is inclined downwards, with an angle of about 15 degrees to 45 degrees with the horizontal plane. When the concrete is discharged from the outlet 1-3, it will slide down along the guide trough 13 to the designated position, which is convenient for collecting the concrete. During the unloading process, the mixing blade 4 continues to mix the concrete, which can prevent it from solidifying in the storage hopper. The scraper 5 continuously cleans the concrete inside the outlet 1-3, which can prevent the concrete from staying at the outlet 1-3 for a long time and solidifying. The vibration of the air hammer 10 can further promote the flow of concrete in the hopper body 1-2 and improve the unloading efficiency.
[0032] When unloading is required, the first motor 6, the second motor 9, and the air hammer 10 are started. The second motor 9 drives the baffle 8 to rotate, opening the outlet 1-3 of the storage hopper body 1, allowing the concrete to be discharged through the outlet 1-3 to the guide chute 13, and then discharged to the designated position through the guide chute 13. During unloading, the air hammer 10 works to generate vibration to assist unloading. The first motor 6 drives the rotating shaft 3 to rotate, causing the rotating shaft 3 to drive the mixing blade 4 and the scraper 5 to rotate simultaneously. The mixing blade 4 continuously mixes the concrete to prevent the concrete from solidifying in the storage hopper body 1, and the scraper 5 continuously cleans the concrete stuck inside the outlet 1-3 to prevent the concrete from solidifying inside the outlet 1-3 and affecting subsequent unloading.
[0033] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
