Description
Technical Field
[0001] The utility model relates to the technical field of concrete pouring, in particular to a layered hopper for T-beam concrete pouring. Background Technique
[0002] A T-beam is a precast concrete member with a structural shape like the letter "T", usually used in the beam-slab structures of bridges and buildings. Due to the design principle of the T-beam, the tensile zone concrete that does not contribute to the bending strength in the rectangular beam is removed, thus saving concrete, reducing the self-weight of the member, and improving the spanning ability. Therefore, when constructing the T-beam, it is usually necessary to pour concrete into the T-beam. When pouring concrete into the T-beam, in order to achieve efficient, safe and quality-controlled construction, the layered pouring method is usually used. The layered pouring of concrete is generally divided into overall layering, sectional layering and inclined layering. The overall layering starts from the short side when pouring concrete and is carried out along the long side direction. It is required that during the progressive pouring process, the second layer of concrete should be poured before the first layer of concrete starts to set; the sectional layering scheme is applicable to the situation where the structural thickness is not large while the area or length is relatively large; the inclined layering scheme is mostly used for structures with a relatively large length. When pouring, the concrete vibration work starts from the lower end of the pouring layer and gradually moves up. The layered pouring method can ensure that the concrete can uniformly and densely fill the mold during the pouring process, thus forming a concrete member with a complete structure and meeting the strength requirements. When pouring the T-beam with layered concrete, in order to evenly transport the concrete to the pouring part of the T-beam, a layered hopper is usually used. The layered hopper is a device specifically used in the concrete pouring process, and its main function is to layer and evenly transport the concrete to the pouring part, thus ensuring the uniformity and compactness of the concrete during the pouring process.
[0003] In the prior art, when pouring the T-beam with layered concrete through a layered hopper, since the concrete contains moisture, the concrete has a certain viscosity. When the layered hopper transports and pours the concrete, it cannot agitate and dredge the concrete well, so that the concrete is prone to caking in the layered hopper, and then it may cause the concrete to be blocked at the discharge port, thus affecting the discharge of the concrete and not being able to ensure the continuity and effect of the layered pouring of the T-beam well. Therefore, in order to solve the above problems, a layered hopper for T-beam concrete pouring is proposed. Content of the Utility Model
[0004] The purpose of the present utility model is to provide a layered hopper for T-beam concrete pouring, so as to solve the problem that when the layered hopper conveys and pours concrete, it cannot agitate and dredge the concrete well, resulting in easy caking of the concrete in the layered hopper, which may cause blockage of the concrete at the discharge port, thus affecting the discharge of the concrete and unable to ensure the coherence and effect of the layered pouring of the T-beam well.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0021] Please refer to Figures 1-4 , an embodiment provided by the present utility model:
[0022] The first motor 23 and the second motor 33 used in this application are products that can be directly purchased on the market, and their principles and connection methods are all well-known prior arts to those skilled in the art, so they will not be elaborated here.
[0023] A layered hopper for T-beam concrete pouring includes a frame body. The frame body includes a support frame 1. The inner surface of the support frame 1 is fixedly connected with a hopper body 11. The bottom end of the hopper body 11 is provided with a discharge pipe 12. Through the setting of the support frame 1, the hopper body 11 can be supported. Through the setting of the discharge pipe 12, concrete can be discharged, so that when pouring concrete into the T-beam, the hopper body 11 can fill the T-beam with concrete, thereby realizing layered pouring.
[0024] An anti-blocking mechanism is arranged inside the hopper body 11. The anti-blocking mechanism includes a support plate 2. The support plate 2 is fixedly connected to the upper surface of the hopper body 11. A first rotating rod 21 is movably connected inside the support plate 2. A stirring rod 22 is fixedly connected to the surface of the first rotating rod 21. A first motor 23 is fixedly installed at the top end of the support plate 2. A connecting rod 24 is fixedly connected to the surface of the first rotating rod 21. A scraping plate 25 is fixedly connected to the surface of the connecting rod 24. A spiral conveyor rod 26 is fixedly connected to the bottom end of the first rotating rod 21. By rotating the first rotating rod 21, the spiral conveyor rod 26 can be driven to rotate accordingly. The spiral conveyor rod 26 can convey concrete, so that the concrete can be stably discharged through the discharge pipe 12, which can avoid congestion and blockage of the concrete in the discharge pipe 12, ensure the stability of the discharge, and thus improve the quality and effect of pouring the T-beam.
[0025] Furthermore, the output end of the first rotating rod 21 is fixedly connected to the output end of the first motor 23. The stirring rods 22 are arranged in eighteen groups and are fixedly connected to the first rotating rod 21. Through the setting of the stirring rods 22, the concrete in the hopper body 11 can be stirred, which is convenient for the mixing of the concrete and can avoid caking of the concrete in the hopper body 11, thus affecting the discharge.
[0026] Further, one end of the connecting rod 24 is fixedly connected to the first rotating rod 21, and the other end of the connecting rod 24 is fixedly connected to the scraping plate 25. The spiral conveyor rod 26 is movably arranged inside the discharge pipe 12. By connecting the first rotating rod 21 and the scraping plate 25 through the connecting rod 24, when the first rotating rod 21 rotates, the connecting rod 24 can drive the scraping plate 25 to rotate accordingly. Furthermore, the scraping plate 25 can scrape the inner wall of the hopper body 11, which can prevent the adhesion of concrete and avoid the accumulation on the surface of the hopper body 11, thereby reducing the risk of blockage.
[0027] Further, a knocking mechanism is arranged on the surface of the hopper body 11. The knocking mechanism includes a connecting plate 3, the connecting plate 3 is fixedly connected to the surface of the hopper body 11, a second rotating rod 31 is movably connected inside the connecting plate 3, an eccentric turntable 32 is fixedly connected to the top end of the second rotating rod 31, a second motor 33 is fixedly installed at the bottom end of the connecting plate 3, a movable groove 34 is opened inside the connecting plate 3, a limiting rod 35 is fixedly connected to the inner wall of the movable groove 34, a movable rod 36 is movably connected to the surface of the limiting rod 35, a rubber block 37 is fixedly connected to the surface of the movable rod 36, and a spring 38 is fixedly connected to the surface of the movable rod 36. By driving the eccentric turntable 32 to rotate through the second rotating rod 31, it can be realized that the eccentric turntable 32 squeezes the movable rod 36, and further the rubber block 37 knocks on the discharge pipe 12, which is convenient for the concrete to fall better through the discharge pipe 12, and thus the pouring efficiency can be improved.
[0028] Further, the end of the second rotating rod 31 away from the eccentric turntable 32 is fixedly connected to the output end of the second motor 33. The movable rod 36 is movably arranged inside the movable groove 34. By the arrangement of the movable groove 34 in cooperation with the setting of the limiting rod 35, the movable rod 36 can stably move under the action of the eccentric turntable 32.
[0029] Further, one end of the spring 38 is fixedly connected to the movable groove 34, and the other end of the spring 38 is fixedly connected to the movable rod 36. By the setting of the spring 38, when the eccentric turntable 32 cancels the extrusion of the movable rod 36, the movable rod 36 can drive the rubber block 37 to reset under the action of the spring 38.
[0030] Working principle: When in use, the first motor 23 is electrically connected to an external power supply. The operator starts the first motor 23 by pressing the switch. The operation of the first motor 23 drives the first rotating rod 21 to rotate, and the stirring rod 22 will rotate accordingly under the action of the first rotating rod 21. Thus, it can realize the mixing of concrete by the stirring rod 22, avoiding the caking of concrete. The connecting rod 24 can drive the scraping plate 25 to rotate accordingly under the action of the first rotating rod 21, thereby realizing the scraping of the inner wall of the hopper body 11 by the scraping plate 25, avoiding the accumulation and adhesion of concrete, and facilitating the better participation of the scraped concrete in the mixing. The setting of the screw conveyor rod 26 can convey the concrete during the rotation of the first rotating rod 21, enabling the stable discharge of the concrete and avoiding the blockage of the concrete in the discharge pipe 12;
[0031] The second motor 33 is electrically connected to an external power supply. The operator starts the second motor 33 by pressing the switch. The operation of the second motor 33 drives the second rotating rod 31 to rotate, and the eccentric turntable 32 will rotate under the action of the second rotating rod 31. When the eccentric turntable 32 rotates and squeezes the movable rod 36, the movable rod 36 will move inside the movable groove 34 and on the surface of the limiting rod 35. Thus, the rubber block 37 moves under the action of the movable rod 36 and knocks on the discharge pipe 12. At this time, the spring 38 is in a contracted state, which can make the concrete fall better and further reduce the risk of blockage; When the eccentric turntable 32 rotates and cancels the extrusion of the movable rod 36, the movable rod 36 will reset under the rebounding action of the spring 38, and thus the rubber block 37 will reset accordingly.
