Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a concrete pouring guide mechanism for road curb construction. Background Technology

[0002] In road construction, the construction of curbs is an important step. Curbs not only define the boundaries of the road, but also protect the road surface, guide rainwater drainage, and beautify the road landscape. Concrete pouring guide mechanisms are devices used in road construction and other scenarios to assist in concrete pouring operations and ensure that the concrete is poured in the predetermined direction and position.

[0003] A search revealed Chinese Patent Publication No. CN221345190U, which discloses a concrete pouring guide mechanism for road curbstone construction. The mechanism includes a chute whose upper end engages with the output end of a cement mixer truck, and a material discharge chute positioned within and sliding along the chute. The material discharge chute has discharge ports on both sides at its bottom, and a baffle plate at its bottom. During operation, the upper end of the chute engages with the output end of the cement mixer truck, and the material discharge chute is moved so that its lower end aligns with the outer side of the curbstone. The cement mixer truck moves forward, and the concrete, after passing through the chute and the material discharge chute, falls through the discharge ports onto the outer side of the curbstone. This achieves automatic concrete pouring, improves construction efficiency, and reduces labor intensity.

[0004] In the aforementioned prior art, "concrete falls through the chute and drop chute to the outside of the curbstone through the discharge port, realizing automatic concrete pouring, improving construction efficiency, and reducing labor intensity." However, this device automatically pours concrete using inclination and the concrete's own weight. When the concrete passes through the chute and drop chute, due to different construction requirements, the concrete's spread is different, and it is easy to overflow from the top and not flow out through the device's inclination. When it is necessary to improve construction efficiency, the concrete discharge speed will also increase, which will cause concrete overflow and waste, reducing construction efficiency and speed. Therefore, a concrete pouring guide mechanism for curb construction in road engineering is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a concrete pouring guide mechanism for road curb construction, which aims to improve the problem in the prior art where the brush plate is designed in a straight line, and when it comes into contact with road debris in front, the debris is difficult to push to the sides, thus accumulating in front of the brush plate and making it difficult for the device to move forward normally.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A concrete pouring guide mechanism for road curb construction includes a material drop pipe, an extension mechanism on the outer side of the top of the material drop pipe, a guide mechanism fixedly connected to the bottom of the material drop pipe, an extension pipe on the outer side of the extension pipe fixedly connected to the top of the material drop pipe, a transport pipe slidably connected to the outer side of the extension pipe, a groove on the outer side of the transport pipe, an adjustment component fixedly connected to the outer side of the extension pipe, two support components fixedly connected to the transport pipe on the side away from the groove, a receiving port fixedly connected to the top of the transport pipe, a drive motor fixedly connected to the transport pipe on the side away from the extension pipe, and a transport paddle fixedly connected to the output end of the drive motor.

[0008] The above technical solution involves: an extension pipe installed on the outer side of the top of the discharge pipe; a transport pipe slidably connected to the outside of the extension pipe; a chute on the transport pipe; an adjustment component on the extension pipe; two support components on one side of the transport pipe; a receiving port at the top; and a drive motor installed on the other side. The motor output is connected to a transport paddle. Concrete enters the transport pipe through the receiving port, and the drive motor rotates the transport paddle, propelling the concrete within the transport pipe. The adjustment component can adjust the position of the transport pipe on the extension pipe, and the support components provide support. Finally, the concrete enters the discharge pipe through the extension pipe for pouring.

[0009] As a further description of the above technical solution:

[0010] The guiding mechanism includes two limiting plates. The tops of the two limiting plates are fixedly connected to the bottom sides of the discharge tube. Movable grooves are provided on the adjacent sides of the two limiting plates, and adjustment grooves are provided on the more distant sides of the two limiting plates. A connecting rod is rotatably connected to the adjacent sides of the limiting plates and the discharge tube, and a guide plate is fixedly connected to the outside of the connecting rod.

[0011] The above technical solution involves two limiting plates of the guiding mechanism set on both sides of the bottom of the discharge pipe. The side of the limiting plates that is closer to each other has a movable groove, and the side that is farther away has an adjustment groove. A guide plate is fixedly connected to the connecting rod that is rotatably connected to the limiting plate and the side of the discharge pipe. The movable groove can provide space for the guide plate to move. Rotating the connecting rod drives the guide plate to rotate, and the guide plate guides the material falling from the discharge pipe.

[0012] As a further description of the above technical solution:

[0013] Both sides of the connecting rod are fixedly connected to limiting posts, and two locking posts are fixedly connected to the adjacent side of the two limiting posts. Both limiting posts are fixedly connected to movable handles.

[0014] The above technical solution involves limiting posts on both sides of the connecting rod, with two locking posts on each limiting post. A movable handle is located outside the limiting posts. By operating the movable handle, the limiting posts are moved, thereby using the locking posts to achieve the corresponding limiting and sliding functions.

[0015] As a further description of the above technical solution:

[0016] The locking pin is slidably connected inside the adjusting groove, and the guide plate is rotatably connected to the inside of the discharge pipe.

[0017] Through the above technical solution: the clamping column can slide in the adjustment groove, and the guide plate can rotate in the discharge pipe. The sliding of the clamping column in the adjustment groove, combined with the rotation of the guide plate in the discharge pipe, realizes the control of the direction of material flow.

[0018] As a further description of the above technical solution:

[0019] The adjusting assembly includes a connecting ring, the outside of which is fixedly connected to the outside of the extension tube, and a tightening member is threadedly connected to the inside of the connecting ring. A support ring is fixedly connected to the inside of the tightening member.

[0020] The above technical solution involves an adjustment component comprising a connecting ring, a tightening element, and a support ring. By operating the tightening element, its position within the connecting ring is changed using a threaded structure, thereby moving the support ring to achieve adjustment and fixation.

[0021] As a further description of the above technical solution:

[0022] The outer part of the connecting ring is slidably connected to the inside of the groove, and the outer part of the support ring is supported on the outside of the transport pipe;

[0023] Through the above technical solution: the connecting ring can slide in the groove, the support ring supports the transport pipe, the connecting ring slides in the groove to change its position, thereby driving the support ring to move, so that the support ring provides support for the transport pipe at different positions, so as to meet the support needs of the transport pipe in different states.

[0024] As a further description of the above technical solution:

[0025] The support assembly includes a support rod, which is externally fixedly connected to the transport pipe on the side away from the chute, and internally slidably connected to a fixed foot.

[0026] The above technical solution involves a support assembly consisting of a support rod and fixed feet. By sliding the fixed feet within the support rod, the overall length of the support assembly can be adjusted, thereby providing stable support for the transport pipe and adapting to different devices.

[0027] As a further description of the above technical solution:

[0028] The transport paddle is externally rotatably connected to the inside of the transport pipe, and the discharge pipe is supported externally by the extension pipe.

[0029] Through the above technical solution: the transport paddle can rotate inside the transport pipe, and the drive motor drives the transport paddle to rotate inside the transport pipe, thereby realizing the transport of materials inside the transport pipe under the action of the rotating transport paddle.

[0030] This utility model has the following beneficial effects:

[0031] 1. In this utility model, the structure of the drive motor drives the structure of the transport paddle. After the drive motor is powered on, the rotation of its output end can directly cause the transport paddle to rotate at high speed. Since the transport paddle is located inside the transport pipe, it will generate a pushing force on the concrete located in the transport pipe during its rotation. Through the sliding connection between the transport pipe and the extension pipe, the extension pipe can slide and adjust its position along the transport pipe. When the transport paddle pushes the concrete, the concrete will move in the transport pipe and fall to the construction position through the drop pipe, thereby realizing the efficient transportation of concrete to the pouring point. The transport distance can be flexibly adjusted according to the actual construction needs, further improving the convenience and applicability of concrete pouring guidance.

[0032] 2. In this utility model, the cooperation between the limiting plate and the movable groove makes the guide plate move more flexibly within a certain range, thereby allowing the material's falling path to be adjusted according to needs. With the cooperation of the adjusting groove and the connecting rod, parameters such as the angle of the guide plate can be adjusted, making it convenient for workers to adjust the angle even when it is not visible. By rotating the guide plate, the falling direction and speed of the material can be changed, avoiding problems such as excessive impact and scattering caused by the material falling directly vertically. This achieves orderly falling of materials and improves the efficiency and quality of the material dropping work. Attached Figure Description

[0041] 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.

[0042] Reference Figure 1 An embodiment of this utility model is provided: a concrete pouring guide mechanism for road curb construction, including a material drop pipe 1, an extension mechanism 2 is provided on the outer side of the top of the material drop pipe 1, and a guide mechanism 3 is fixedly connected to the bottom of the material drop pipe 1. The material drop pipe 1 serves as a channel for concrete to fall from the extension mechanism 2 to the guide mechanism 3, guiding the concrete to fall into the construction area.

[0043] Specifically, after the concrete enters the discharge pipe 1 from the extension mechanism 2, it flows downward along the inner wall of the discharge pipe 1 under the action of gravity and finally reaches the guide mechanism 3.

[0044] Reference Figure 2 , Figure 3 and Figure 5The extension mechanism 2 includes an extension tube 21. The outer side of the extension tube 21 is fixedly connected to the top outer side of the discharge tube 1. The extension tube 21 slides on the transport tube 23 connected to the discharge tube 1 to realize the adjustable function of the extension mechanism 2. The transport tube 23 is slidably connected to the outside of the extension tube 21. The transport tube 23 transports concrete and allows the extension tube 21 to slide inside it, changing the length of the extension mechanism 2. A groove 24 is opened on the outside of the transport tube 23 to assist the sliding adjustment of the transport tube 23 on the extension tube 21. An adjustment component 22 is fixedly connected to the outside of the extension tube 21.

[0045] The adjusting assembly 22 includes a connecting ring 221, which provides a mounting base for the tightening member 222 and the support ring 223. The connecting ring 221 is externally fixedly connected to the outside of the extension tube 21. The tightening member 222 is internally threadedly connected to the connecting ring 221. The tightening member 222 can be rotated to adjust the pressure between the support ring 223 and the transport tube 23. The support ring 223 is internally fixedly connected to the tightening member 222. The support ring 223 cooperates with the tightening member 222 to fix the position of the transport tube 23 by friction. Two support assemblies 28 are fixedly connected to the side of the transport tube 23 away from the slide 24.

[0046] The support assembly 28 includes a support rod 281, which provides a mounting and sliding base for the fixed foot 282. The support rod 281 is externally fixedly connected to the transport pipe 23, i.e., on the side away from the chute 24. The fixed foot 282 is internally slidably connected to the support rod 281, which provides stable support for the transport pipe 23. The top of the transport pipe 23 is fixedly connected to a receiving port 25, which is used to receive externally delivered concrete, allowing the concrete to smoothly enter the transport pipe 23.

[0047] A drive motor 26 is fixedly connected to the side of the transport pipe 23 away from the extension pipe 21. The drive motor 26 provides power to the transport paddle 27, driving the transport paddle 27 to rotate, thereby pushing the concrete to move inside the transport pipe 23. The output end of the drive motor 26 is fixedly connected to the transport paddle 27. The transport paddle 27 rotates under the drive of the drive motor 26, pushing the concrete to move inside the transport pipe 23 and assisting in transporting the concrete to the discharge pipe 1. The outer part of the connecting ring 221 is slidably connected to the inside of the chute 24. The outer part of the support ring 223 is supported on the outside of the transport pipe 23. The outer part of the transport paddle 27 is rotatably connected to the inside of the transport pipe 23. The discharge pipe 1 is supported on the outside of the transport pipe 23 through the extension pipe 21.

[0048] Specifically, during construction, bolts are used to fix the bottom of the fixing foot 282 to the concrete truck, thus fixing the device to the concrete truck. The extension pipe 21 can slide inside the transport pipe 23. The overall length of the extension mechanism 2 can be changed by adjusting the position of the extension pipe 21. When the extension pipe 21 needs to be fixed, the support ring 223 is rotated to drive the tightening member 222, so that the support ring 223 approaches and presses the transport pipe 23. When the extension pipe 21 needs to be adjusted, the tightening member 222 is rotated in the opposite direction to reduce the pressure of the support ring 223 on the transport pipe 23. The concrete enters the transport pipe 23 through the receiving port 25. When the power is turned on, the drive motor 26 starts to work, and its output end drives the transport paddle 27 to rotate inside the transport pipe 23.

[0049] Reference Figure 1 , Figure 4 and Figure 6 The guiding mechanism 3 includes two limiting plates 31. The tops of the two limiting plates 31 are fixedly connected to the bottom sides of the discharge pipe 1. The limiting plates 31 provide a foundation for the opening of the movable groove 32 and the adjusting groove 33. The movable groove 32 is opened on the adjacent side of the two limiting plates 31. The movable groove 32 provides a space for the rotation of the guide plate 35, ensuring that the guide plate 35 can rotate freely around the connecting rod 34. The adjusting groove 33 is opened on the far side of the two limiting plates 31. The adjusting groove 33 provides a sliding track for the locking post 37. By sliding the locking post 37 in the adjusting groove 33, the angle of the guide plate 35 can be adjusted and limited. The connecting rod 34 is rotatably connected to the adjacent side of the limiting plate 31 and the discharge pipe 1. The connecting rod 34 enables the guide plate 35 to rotate around it and provides an installation foundation for the limiting post 36. The guide plate 35 is fixedly connected to the outside of the connecting rod 34. The guide plate 35 guides the concrete falling from the discharge pipe 1 to the designated construction area and changes the falling direction of the concrete.

[0050] Both sides of the connecting rod 34 are fixedly connected to limiting posts 36. The limiting posts 36 provide the mounting base for the locking posts 37 and the movable handle 38. By pulling the movable handle 38, the limiting posts 36 are moved, thereby adjusting the angle of the guide plate 35. Two locking posts 37 are fixedly connected to the adjacent side of the two limiting posts 36. The locking posts 37 slide in the adjustment groove 33 to adjust and limit the angle of the guide plate 35. Movable handles 38 are fixedly connected to the outside of the two limiting posts 36. The movable handles 38 are convenient for the operator to pull. The locking posts 37 are slidably connected inside the adjustment groove 33. The outside of the guide plate 35 is rotatably connected inside the discharge pipe 1.

[0051] Specifically, the limiting plate 31 is fixedly connected to the discharge pipe 1 at the top, and has a movable groove 32 and an adjusting groove 33. The movable groove 32 provides space for the connecting rod 34 to move, and the adjusting groove 33 provides space for the locking post 37 to move. When it is necessary to adjust the angle of the guide plate 35, the movable handle 38 is pulled, which causes the limiting post 36 and the locking post 37 to slide in the adjusting groove 33, thereby changing the angle of the guide plate 35. After the angle of the guide plate 35 is adjusted, the locking post 37 can be fixed in the adjusting groove 33, thus fixing the angle of the guide plate 35. After the concrete falls from the discharge pipe 1, it impacts the guide plate 35, and the guide plate 35 guides the concrete to the construction area according to the adjusted angle.

[0052] Working principle: The external concrete conveying equipment delivers concrete to the receiving port 25. Since the receiving port 25 is connected to the conveying pipe 23, the concrete smoothly enters the conveying pipe 23. At this time, the drive motor 26 is powered on and begins to work. The output end of the drive motor 26 drives the conveying paddle 27 to rotate inside the conveying pipe 23. The blades of the conveying paddle 27 push the concrete, overcoming the friction between the concrete and the inner wall of the conveying pipe 23, causing the concrete to be transported along the conveying pipe 23 towards the discharge pipe 1. The extension pipe 21 inside the conveying pipe 23 is adjusted, and the extension pipe 21 outside... The connecting ring 221 slides in the groove 24, and the two work together to adjust the position of the extension tube 21. After the adjustment is completed, the tightening part 222 inside the connecting ring 221 is rotated. The tightening part 222 makes the support ring 223 move closer to the transport tube 23 and press it. The support ring 223 fixes the position of the extension tube 21 inside the transport tube 23. One end of the support rod 281 in the support assembly 28 is fixed on the transport tube 23. The support position can be adjusted by the fixing foot 282. The bottom of the fixing foot 282 is fixed on the concrete truck to ensure that the transport tube 23 is placed stably.

[0053] After concrete enters the discharge pipe 1 from the transport pipe 23, it flows downward along the inner wall of the discharge pipe 1 under the action of gravity. It is connected to the discharge pipe 1 through the top of the limiting plate 31. The movable groove 32 of the limiting plate 31 provides space for the rotation of the guide plate 35, and the adjustment groove 33 provides a track for the sliding of the locking post 37. When the operator pulls the movable handle 38, the movable handle 38 drives the limiting post 36 to move. The limiting post 36 drives the guide plate 35 to rotate through the connecting rod 34. The locking post 37 on the limiting post 36 slides in the adjustment groove 33. When the guide plate 35 is adjusted to a suitable angle, the concrete falls from the discharge pipe 1 and impacts the guide plate 35. The guide plate 35 guides the concrete to the designated construction area according to the adjusted angle, so as to achieve accurate concrete pouring.

[0054] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present 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 the present utility model should be included within the protection scope of the present utility model.
