Description

Technical Field

[0001] This utility model relates to the field of concrete processing technology, specifically to an anti-clogging concrete pouring hopper. Background Technology

[0002] In concrete pouring construction, traditional pouring hoppers mainly rely on gravity to deliver concrete. These hoppers typically consist of a hopper body, an inlet, and an outlet. The interior of the hopper body is mostly a smooth plane or a simple vertical structure, lacking effective flow guiding and mixing devices. When concrete enters the hopper, the cement paste has strong adhesion during the static process, easily adhering to the inner wall of the hopper to form a wall-hanging layer, which gradually solidifies and hardens over time. At the same time, the aggregate in the concrete is prone to accumulate and get stuck at the corners of the hopper and at the outlet, especially when pouring large-diameter aggregates or concrete with low slump.

[0003] Furthermore, the lack of a mixing function makes concrete prone to segregation within the hopper, leading to reduced fluidity and further exacerbating the risk of blockage. In actual construction, the concrete pouring of some super high-rise buildings, due to the large volume and long duration of each pour, often results in frequent blockages in traditional hoppers. After a certain number of concrete pours, the machine needs to be stopped two to three times for cleaning. In underwater operations such as bridge pile foundation pouring, once the hopper is blocked, it not only delays the construction period but may also cause serious quality accidents such as pile breakage due to interrupted pouring. To ensure construction can proceed, construction personnel need to frequently stop the machine to clean the hopper, which not only reduces construction efficiency and increases labor costs but may also affect the continuity of concrete pouring due to untimely cleaning, leading to a decline in project quality and making it difficult to meet the requirements of modern construction projects for efficient and stable concrete pouring. Therefore, an anti-blockage concrete pouring hopper is proposed. Utility Model Content

[0004] This invention proposes an anti-clogging concrete hopper. The upper part of the stirring blades, driven by a motor, adopts an elliptical shape and angular structure. With an evenly spaced layout, it continuously cuts and mixes the concrete, effectively preventing cement solidification and segregation, and maintaining a good fluid state of the concrete. The inclined guide grooves on the inner wall of the hopper utilize the component of gravity to convert the adhesion force between the concrete and the inner wall as it slides down into a flow driving force. The straight groove design eliminates sharp angles and avoids the risk of concrete and aggregate getting stuck.

[0005] According to one aspect, at least one embodiment of the present invention provides an anti-clogging concrete pouring hopper, comprising: a pouring hopper body, an inlet provided at the top of the pouring hopper body, a motor provided at the top of the inlet, and a rotating rod fixedly connected to the output end of the motor through the pouring hopper body;

[0006] A rotating sleeve block is fitted on the outer wall of the rotating rod, and an agitator blade is fixedly connected to the outer end of the rotating sleeve block;

[0007] The rotating rod is fixedly connected to an agitating spiral plate, the outer end of the agitating spiral plate is fixedly connected to a flow divider plate, and the outer wall of the flow divider plate is fixedly connected to an agitating block.

[0008] For example, at least one embodiment of the present invention provides an anti-clogging concrete hopper, which further includes: the rotating sleeve block is located in the upper part of the rotating rod, and the rotating sleeve block and the stirring blades are arranged in three sets on the rotating rod, with the three sets of stirring blades being spaced at the same distance.

[0009] For example, at least one embodiment of the present invention provides an anti-clogging concrete hopper, which further includes: the inner blades of the agitator blade are arranged in an elliptical shape, and the two ends of the inner blades of the agitator blade are provided with sharp edges.

[0010] For example, at least one embodiment of the present invention provides an anti-clogging concrete hopper, which further includes: an inclined guide pattern provided on the inner wall of the hopper body, wherein the inclined angle is 20 degrees with the horizontal plane.

[0011] For example, at least one embodiment of the present invention provides an anti-clogging concrete hopper, which further includes: the agitating screw plate and the rotating rod are in contact with each other, and the agitating screw plate is located in the lower half of the rotating rod.

[0012] For example, at least one embodiment of the present invention provides an anti-clogging concrete hopper, which further includes: the cross-sectional shape of the diversion plate is set in an "L" shape, and the diversion plate and the stirring screw plate are set in the same winding path.

[0013] For example, at least one embodiment of the present invention provides an anti-clogging concrete hopper, which further includes: a connecting pad is adhered to and fixed on the outer wall of the diversion plate, and the agitator is fixed to the outer wall of the diversion plate by the connecting pad.

[0014] For example, at least one embodiment of the present invention provides an anti-clogging concrete hopper, which further includes: the agitator block has a wedge-shaped cross-section.

[0015] The working principle and beneficial effects of this utility model are as follows: The upper part of the stirring blades, driven by the motor to rotate the rotating rod, adopts an elliptical shape and angular structure. With an evenly spaced layout, it continuously cuts and mixes the concrete, effectively preventing cement solidification and segregation, and maintaining a good fluid state of the concrete. The inclined guide pattern on the inner wall of the hopper utilizes the component of gravity to convert the adhesion force between the concrete and the inner wall when it slides down into a flow driving force. The straight-line pattern design eliminates sharp angle turns and avoids the risk of concrete and aggregate getting stuck.

[0016] The lower half of the rotating rod, consisting of an agitating spiral plate, a diverting plate, and an agitating block, forms an active flow guiding structure. The agitating spiral plate spirally pushes the concrete downwards, while the "L"-shaped diverting plate guides the material to the side wall of the hopper, expanding the flow space. The wedge-shaped agitating block further cuts the concrete, reducing its viscosity. The three components work together to create a spiraling, downward, and uniformly diffused flow path within the hopper, preventing central accumulation and blockage. Simultaneously, the elastic connecting pad between the diverting plate and the agitating block reduces impact wear on components, extending the equipment's service life. Through the multi-structure linkage of mechanical mixing, gravity guidance, and active pushing, this hopper significantly reduces the number of downtime cleanings. While ensuring the continuity of concrete pouring, construction efficiency is effectively improved, and potential engineering quality hazards caused by blockages can be avoided.

[0028] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0029] Refer to the instruction manual appendix Figure 1-4 A type of anti-clogging concrete pouring hopper includes: a pouring hopper body 1, an inlet 2 at the top of the pouring hopper body 1, a motor 3 at the top of the inlet 2, and a rotating rod 4 fixedly connected to the output end of the motor 3 through the pouring hopper body 1.

[0030] A rotating sleeve block 5 is fitted on the outer wall of the rotating rod 4, and an agitator blade 6 is fixedly connected to the outer end of the rotating sleeve block 5. The rotating sleeve block 5 and the rotating rod 4 are connected by a key structure to achieve synchronous rotation of the rotating sleeve block 5 and the rotating rod 4. The agitator blade 6 is fixedly connected to the outer end of the rotating sleeve block 5 by welding. The three sets of rotating sleeve blocks 5 and agitator blades 6 are evenly distributed in the upper half of the rotating rod 4. This equidistant arrangement allows the concrete to be uniformly mixed in the upper area of ​​the hopper without dead angles. During the process of concrete falling from the inlet 2 into the hopper, it can be uniformly agitated by the agitator blades 6 every time it travels the same distance, effectively avoiding the cement solidification caused by local concrete stillness.

[0031] The internal blades of the agitator blade 6 are elliptical in shape. This design fully considers the flow characteristics of concrete and the mixing effect. As the blades rotate with the rotor 4, the elliptical shape allows for a larger contact area with the concrete compared to other shapes, enhancing the mixing coverage. The two ends of the internal blades of the agitator blade 6 have sharp edges. When the agitator blade 6 rotates, these edges act like sharp knives, penetrating deep into the concrete to powerfully cut the cement lumps. Through this cutting action, the cement particles and aggregates that were originally clustered together are effectively dispersed, the internal structure of the concrete is reshaped, and its fluid state changes from the original viscous and poorly fluid state to a state with good fluidity, laying the foundation for smooth subsequent material feeding. During the blade manufacturing process, a forging process is used to ensure that the internal structure of the blade is dense, with high strength and toughness, and can withstand the impact and wear caused by long-term concrete mixing.

[0032] The inner wall of the hopper body 1 is provided with inclined guide patterns, with an inclination angle of 20 degrees to the horizontal plane. The guide patterns adopt a straight line design, and the width and depth of the patterns were determined after extensive simulation tests and actual engineering verification. The width is sufficient to guide the concrete to slide smoothly, while the depth will not cause the concrete to stagnate within the patterns. This design cleverly utilizes the component of gravity to guide the concrete to slide down the inclined surface, effectively reducing the adhesion between the concrete and the inner wall of the hopper in the vertical direction. The straight lines avoid sharp angles, fundamentally eliminating the risk of cement getting stuck at the patterns, allowing the concrete to flow smoothly down the hopper along the inner wall. The guide patterns are made using laser engraving technology to ensure smooth edges, reducing the frictional resistance between the concrete and the edges of the patterns. At the same time, the inner wall of the hopper is polished to further reduce the adhesion of the concrete.

[0033] The lower half of the rotating rod 4 is fixedly connected to the agitating screw plate 7 using a full welding process. Through multi-layer and multi-pass welding, the two are ensured to fit tightly and the connection is firm and reliable, preventing loosening or detachment. The agitating screw plate 7 promotes the movement of concrete downwards in the hopper and ensures that the mixing process is thorough and uniform, preventing incomplete mixing. A diverter plate 8 is welded and fixed to the outer end of the agitating screw plate 7. The diverter plate 8 has an "L"-shaped cross-section and uses the same winding path as the agitating screw plate 7. When the agitating screw plate 7 rotates, the "L"-shaped diverter plate 8 can guide the concrete towards the side wall of the hopper, changing the flow direction of the concrete and making the concrete more evenly distributed in the hopper. This effectively improves the efficiency of material discharge and avoids the problem of concrete accumulating in the center of the hopper, which leads to poor material discharge.

[0034] The outer wall of the diverter plate 8 is bonded and fixed with a connecting pad 9 by a high-strength adhesive. The connecting pad 9 is made of rubber with good elasticity and wear resistance. This rubber material can maintain its performance stability and is not easily damaged during long-term contact with concrete. The agitator block 10 is fixed to the outer wall of the connecting pad 9 by bolts. The presence of the connecting pad 9 forms an elastic buffer structure between the diverter plate 8 and the agitator block 10. When the agitator block 10 collides and rubs with the concrete during operation, the connecting pad 9 can absorb part of the impact force, reduce the wear between the diverter plate 8 and the agitator block 10, thereby extending the service life of the entire component and reducing the maintenance cost of the equipment.

[0035] The agitator block 10 has a wedge-shaped cross-section. The wedge shape allows it to penetrate deep into the concrete as it rotates with the diverter plate 8, performing secondary cutting of the cement and aggregate mixture. Through this secondary cutting action, the concrete particles are further refined, the viscosity of the concrete is reduced, and the fluidity is significantly improved. Even relatively viscous concrete can flow smoothly under the action of the agitator block 10, effectively preventing blockage inside the hopper.

[0036] The motor 3 drives the rotating rod 4 to rotate, and the rotating sleeve 5 and the stirring blade 6 of the upper part of the rotating rod 4 rotate accordingly, which fully stirs the cement inside the hopper body 1, changes its fluid state, and prevents the cement from solidifying. The stirring spiral plate 7, the diverting plate 8 and the stirring block 10 of the lower part of the rotating rod 4 work together. The spiral structure of the stirring spiral plate 7 provides a stable downward pushing force, the diverting plate 8 guides the concrete to be evenly distributed, and the stirring block 10 cuts the concrete to improve its fluidity. The three work together to enable the cement to be smoothly discharged from the hopper body 1. Meanwhile, the inclined guide patterns on the inner wall of the hopper body 1 utilize gravity to assist the flow of concrete. Multiple structures work together synergistically to ultimately prevent clogging. In practical engineering applications, this anti-clogging concrete hopper effectively reduces the number of downtimes for cleaning due to clogging, improves the efficiency of concrete pouring, and ensures the smooth progress of construction. The hopper can operate continuously and stably without frequent downtime for cleaning. Furthermore, its anti-clogging performance has been fully verified in projects with high requirements for concrete fluidity, such as bridge pile foundation pouring, ensuring that concrete can be smoothly poured to the designated location and avoiding quality problems such as broken piles caused by clogging.
