Description

Technical Field

[0001] This utility model relates to the field of building construction, and in particular to a concrete funnel chute device. Background Technology

[0002] In municipal construction, ready-mixed concrete is typically used and transported to the construction site by concrete mixer trucks. For concrete work on sloping surfaces, where stable concrete transport is difficult, concrete chute structures suitable for slopes are often employed. These chute structures consist of a channel extending downwards along the slope, with an open top to allow concrete to flow downwards. This structure utilizes gravity to transport concrete from higher to lower elevations, eliminating the need for additional power sources and personnel. Furthermore, the well-designed guide walls effectively prevent leakage, segregation, and splashing during transport, improving construction safety and efficiency. However, this concrete chute structure has drawbacks. The chute's coverage area on the slope is limited, and the concrete is directly delivered to its upper end by the concrete mixer truck and slid downwards. After one section of the slope is completed, both the chute and the mixer truck must be moved to the next location, requiring continuous alternation for slope concrete pouring. This process involves numerous steps and low efficiency, requiring improvement. Utility Model Content

[0003] To address the aforementioned problems, this utility model proposes a concrete funnel chute device.

[0004] The technical solution of this utility model is: a concrete funnel chute device, including a support and a conical hopper. The conical hopper is placed on the upper end of the support. The support is a square frame, which includes a seat plate and a platform plate arranged in parallel. Support legs are provided between the four corners of the seat plate and the platform plate. The support legs are vertically welded and fixed between the seat plate and the platform plate. The conical funnel is placed on the platform plate. A cylindrical discharge pipe is provided at the lower end of the conical funnel. The lower end of the discharge pipe is sealed by a bottom plate, which is supported in the middle of the platform plate. Connecting pipes are provided radially at the front end and both sides of the discharge pipe. The outer end of the connecting pipe is connected to a concrete chute through a flange. The concrete chute is arranged at a downward inclination.

[0005] Preferably, a shut-off valve is installed between the joint pipe and the concrete chute, and the shut-off valve is equipped with a handwheel for driving it to open or close.

[0006] Preferably, the platform plate has a rear frame at the rear, and the upper part of the rear frame has a rear inclined support plate that matches the size of the outer side of the conical hopper. The rear inclined support plate includes a main body in the middle and two end plates connected to the two ends of the main body. The middle and two sides of the front of the platform plate are provided with a front frame A and two front frame B in sequence. There is a certain gap between the front frame A and the front frame B. The upper part of the inner side of the front frame A has a front inclined support plate A that matches the size of the outer side of the conical funnel, and the upper part of the inner side of the front frame B has a front inclined support plate B that matches the size of the outer side of the conical funnel.

[0007] Preferably, a side pipe routing gap is formed between the front frame body B and the rear frame body, and the side connector pipe is inserted into the side pipe routing gap. A front pipe routing gap is formed between adjacent front frame bodies B, and the front connector pipe is inserted into the front pipe routing gap. The size of the pipe routing gap is larger than the size of the connector pipe.

[0008] Preferably, baffles are provided around the seat plate, and the baffles and the seat plate together form a square groove. The two ends of the baffles are welded and fixed to the support respectively.

[0009] Preferably, the concrete chute comprises several short chutes connected end to end by a sleeve structure, and the concrete chute is made of high-strength plastic or metal.

[0010] The beneficial technical effects of this utility model are:

[0011] (1) Multiple connector pipes are set at the discharge port at the lower end of the conical hopper of the chute device. Multiple concrete chutes can be connected to the multiple connector pipes at the same time. These concrete chutes can cover a large slope area at once, and concrete can be delivered to each concrete chute synchronously through the conical hopper. This effectively solves the problem of small coverage area and frequent relocation required by traditional chute structures, which is conducive to improving the efficiency of slope concrete construction and reducing construction costs.

[0012] (2) Due to the closed nature of the chute, the segregation of concrete can be reduced, the uniformity of concrete can be guaranteed, thereby improving the construction quality. Furthermore, the flow rate of concrete can be controlled by adjusting the angle and diameter of the conical funnel and the chute, ensuring the uniform distribution of concrete in the construction area, which is beneficial to ensuring the compactness of the concrete structure.

[0020] Example 1, see appendix Figure 1-5 A concrete chute device includes a support and a conical hopper 1. The support is a square frame, which includes a seat plate 21 and a platform plate 22 arranged in parallel. Support legs 23 are provided between the four corners of the seat plate and the platform plate. The conical hopper is placed on the platform plate 22 and is stably supported by the square frame-shaped support. A cylindrical discharge pipe 11 is provided at the lower end of the conical hopper. The lower end of the discharge pipe is sealed by a bottom plate 12. The concrete entering the conical hopper enters the internal space of the discharge pipe 11 in a timely manner. Connecting pipes 31 are provided radially at the front end and both sides of the discharge pipe 11. The outer end of the connecting pipe is connected to a concrete chute 32 through a flange. The concrete chute is arranged at a downward inclination. A corrugated hose can be connected between the concrete chute 32 and the connecting pipe 31 so that the inclination angle of the concrete chute can be adjusted to adapt to slopes of different gradients.

[0021] A shut-off valve 33 is installed between the joint pipe 31 and the concrete chute 32, which can be used to close the chute in a timely manner.

[0022] The concrete chute 32 includes several short chutes, which are connected end to end by a connecting structure. The number of short chute connections can be freely adjusted according to the location of the slope construction, so that the concrete can accurately reach the construction location.

[0023] When using the chute device in this embodiment, the support is placed on the ground at the upper end of the slope, and then the conical hopper 1 and concrete chute 32 are installed in sequence. The concrete chute covers a large area of ​​the slope pouring area. Then, the concrete mixer truck is moved to the front of the conical hopper and the concrete is discharged into the conical hopper 1. Concrete is simultaneously delivered to each concrete chute 32 through the conical hopper 1. A large area of ​​slope pouring construction can be covered in one location, without the need for frequent relocation, which helps to improve the efficiency of slope concrete construction. If an emergency occurs on the slope surface during the concrete pouring process, the chute can be closed in time by the shut-off valve 33 to avoid a large waste of concrete.

[0024] Example 2, see appendix Figure 1-2 6. This embodiment is basically the same as Embodiment 1, and the similarities will not be repeated. The difference is that: the platform plate 22 is provided with a rear frame 41 at the rear, and the upper part of the rear frame 41 is provided with a rear inclined support plate 42 that matches the size of the outer side of the conical hopper 1. The rear inclined support plate 42 can stably support the rear outer side of the conical hopper 1. The middle and two sides of the front part of the platform plate 22 are provided with a front frame A 43 and two front frame B 44 in sequence. The upper part of the inner side of the front frame A 43 is provided with a front inclined support plate A 45 that matches the size of the outer side of the conical funnel. The upper part of the inner side of the front frame B 44 is provided with a front inclined support plate B 46 that matches the size of the outer side of the conical funnel. One inclined support plate A and two inclined support plates B stably support the front outer side of the conical hopper 1 at the front. Combined with the square frame-shaped stable support, it can ensure that the conical funnel and chute remain stable during the concrete flow process and will not shake or tip over.

[0025] A side pipe passage gap is formed between the front frame body B44 and the rear frame body 41. The side connector pipe 31 is inserted into the side pipe passage gap. A front pipe passage gap is formed between adjacent front frame bodies B44. The front connector pipe 31 is inserted into the front pipe passage gap. This frame structure design can realize the installation and fixation of the conical hopper 1 and the support by means of a set. It can be flexibly arranged according to the actual situation of the construction site and is suitable for various complex construction environments.

[0026] Baffles 24 are provided around the seat plate 21. The baffles 24 and the seat plate 21 form a square trough. When the temperature is low during winter construction in the suburbs, the concrete in the mixer truck has poor flowability when entering the conical hopper 1, and the concrete chute 32 may even become blocked. At this time, wood or other fuel can be placed in the square trough formed by the baffles 24 and the seat plate 21 to heat the conical hopper 1, so as to ensure the smooth construction of the concrete chute 32 and ensure the construction progress.
