[0002] Concrete pouring refers to the construction process of pouring concrete into a formwork until it is plasticized. It is mainly used in civil engineering projects. When pouring concrete into the formwork, it is not allowed to pour it in a concentrated manner to impact the formwork or steel reinforcement cage. When the pouring height is greater than 2 meters, a chute or pipe should be used for material discharge. The free fall height from the discharge pipe to the poured layer should not exceed 1.5 meters. Therefore, funnels are widely used in the concrete pouring process.

[0003] Existing technology, patent document CN203160704U, discloses a funnel for pouring concrete, comprising: a funnel welded from four trapezoidal steel plates, a reinforcing mesh, and a steel pipe. The bottom of the funnel is connected to the steel pipe, the reinforcing mesh is disposed inside it, and a lifting ring is provided at the top. This utility model has a simple structure and low cost, can improve the self-compacting degree of concrete, greatly reduces the risk of non-compacted concrete due to insufficient vibration, and solves the problem of difficulty in controlling the thickness of layered pouring when pouring concrete using traditional methods.

[0004] Although the device has many beneficial effects, the following problems still exist: the lifting ring is inconvenient to fix with external structures of different diameters; secondly, the length of the discharge pipe cannot be adjusted, making it inconvenient to pour concrete in deeper areas.

[0017] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0018] This utility model is described in detail with reference to the schematic diagrams.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] The embodiments of this utility model will now be described in further detail with reference to the accompanying drawings.

[0022] This utility model provides an overall structural schematic diagram of an embodiment of a funnel for pouring concrete, including: Please see Figures 1-5 This embodiment of a concrete pouring funnel includes a funnel, a funnel nozzle 100, a funnel body 110, and a discharge port 120. The above structures are integrally connected. Four fixing blocks 200 are welded to the outer circumference of the funnel nozzle 100. A locking ring 210 is integrally connected to the side wall of the fixing block 200. A toothed buckle 220 is hinged to the end of the locking ring 210. Both the locking ring 210 and the toothed buckle 220 are annular. The locking ring 210 is composed of two semi-ring structures. The two semi-rings are symmetrical about the vertical center line of the fixing block 200. A hinge shaft is welded between the ends of the two semi-rings. The toothed buckle 220 is hinged between the two semi-rings through the hinge shaft. This is so that the toothed buckle 220 can pass through the locking ring 210 to engage with a horizontal pipe 260 with a smaller diameter. A rack 230 is hinged to the inner wall of the fixing block 200. A discharge pipe 300 is inserted into the bottom of the discharge port 120.

[0023] It is worth noting that, in order for the toothed buckle 220 and the locking ring 210 to engage the horizontal pipe 260, specifically, the toothed buckle 220 meshes with the rack 230. The serrated structures on both the rack 230 and the toothed buckle 220 are helical teeth. This is so that when the toothed buckle 220 and the rack 230 are engaged, the toothed buckle 220 can be further locked but cannot be loosened. The horizontal pipe 260 is engaged between the toothed buckle 220 and the locking ring 210. By engaging the toothed buckle 220 with the rack 230, the toothed buckle 220 can be fixed in different positions. By clamping the ring-shaped toothed buckle 220 and the locking ring 210 to engage the tubular structure, the funnel can be engaged with the scaffold pipe or the tubular structure at the end of the crane boom, making it convenient for workers to push or directly suspend it at the bottom of the crane for concrete pouring.

[0024] Next, in order to disengage the rack 230 from the toothed buckle 220, a rod 250 is inserted into the top of the side wall of the rack 230. The rod 250 passes through the fixing block 200. The side wall of the fixing block 200 has a slot for the rod 250 to move. By moving the rod 250, the rack 230 can disengage from the toothed buckle 220 and thus release the toothed buckle 220.

[0025] Meanwhile, in order to enable the rack 230 to be hinged to the inner wall of the fixed block 200, specifically, a rotating shaft is inserted into the bottom end of the side wall of the rack 230, and the rack 230 is hinged to the inner wall of the fixed block 200 through the rotating shaft.

[0026] Furthermore, in order to keep the rack 230 engaged with the toothed buckle 220, two torsion springs 240 are sleeved on the outer circumference of the rotating shaft. The two torsion springs 240 are located on both sides of the rack 230. One end of the torsion spring 240 is connected to the rack 230, and the other end is connected to the fixing block 200. The torsion spring 240 itself causes the rack 230 to rotate continuously in the direction of the toothed buckle 220. This is so that the rack 230 automatically engages with the toothed buckle 220 and will not disengage during the casting process. It is worth noting that, in order to connect and fix the discharge port 120 to the discharge pipe 300, specifically, multiple connecting blocks 130 are welded to the outer circumference of the discharge port 120 and the discharge pipe 300. The connecting blocks 130 between the discharge port 120 and the discharge pipe 300 or between two discharge pipes 300 are fixed by bolts.

[0027] Finally, to make the connection between the discharge pipe 300 and the discharge port 120 tighter, specifically, the top of the discharge pipe 300 is integrally connected with a plate 310, the outer circumference of the plate 310 is threaded, and the bottom of the discharge port 120 and the discharge pipe 300 are provided with slots that match the shape and size of the plate 310. This is to strengthen the connection stability by using threads while enhancing the sealing of the connection and preventing concrete from seeping into the connection.

[0028] In some embodiments, in order for the toothed buckle 220 to engage with a thinner horizontal tube 260, the number of oblique teeth on the toothed buckle 220 can be increased to increase the engagement distance of the toothed buckle 220.

[0029] Combination Figures 1-5 The specific usage process of the concrete pouring funnel in this embodiment is as follows: 1. When installing this device, first hinge the rack 230 to the inner wall of the fixing block 200, then hinge the end of the toothed buckle 220 and the end of the locking ring 210, and finally weld the four fixing blocks 200 to the outer circumference of the funnel nozzle 100. When installing the feed pipe 300, first connect the insert plate 310 to the bottom of the feed port 120 through the threaded connection, and then use bolts to fix the connecting blocks 130 at the corresponding positions on the upper and lower sides. If multiple feed pipes 300 need to be spliced, just repeat the above steps. 2: When using the device, scaffolding or other supports with horizontal pipes 260 can be erected at the location where concrete needs to be poured so that the device can be snapped in place. Workers only need to push the funnel forward to complete the pouring of the construction area. 3: If it is inconvenient to set up a support frame at the construction site, the funnel can be lifted by using the locking ring 210 and the toothed buckle 220 through the hoisting rope or directly by clamping it to the end of the crane arm. If the pouring part is deep, the drop to the pouring surface can be reduced by splicing multiple discharge pipes 300.

[0030] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
