Description

[0002] At present, in the construction of underground projects and tunnel projects, the use of concrete pump trucks to pour concrete is easily restricted by the construction site, and the cost is high. It is easy to cause pipeline blockage and affect the progress of concrete construction. It is necessary to use traditional chutes to transport concrete.
[0003] Chute pouring concrete is non-pumping. When using traditional chutes to transport concrete, the chute needs to be tilted and placed. The concrete flows in the chute by its own gravity and is then transported to the surface to be poured. Since the fluidity of self-unloading concrete is relatively low, once there is a small height difference between the concrete unloading point and the surface to be poured, the chute tilt angle is small, and the conveying distance is long, it is necessary to add special concrete admixtures to the concrete or manually assist in shoveling to ensure the conveying efficiency of the concrete, which will increase material costs and labor costs. In addition, the conveying efficiency is easily affected by the tilt angle of the chute and the self-flowing nature of the concrete, which in turn affects the progress of concrete construction.

[0017] Reference Figure 1As shown, the utility model provides a technical solution: a concrete chute device, including a U-shaped trough plate 1, two oblique supports 31 are hinged at the bottom of the U-shaped trough plate 1, an adjusting bolt 32 is rotatably arranged between the two oblique supports 31, the outer surface of the adjusting bolt 32 is located at the middle section of the oblique support 31 and a support foot 3 is fixedly installed, and the angle of the U-shaped trough plate 1 is adjusted by rotating the adjusting bolt 32, the top of the U-shaped trough plate 1 is rotatably connected to a shaft rod 21 that passes through the two side walls of the U-shaped trough plate 1, the shaft rod 21 is located in the middle section inside the U-shaped trough plate 1 and a driving wheel 2 is fixedly installed, when concrete is poured on the U-shaped trough plate 1, the impact force of the concrete causes the driving wheel 2 to rotate, and the rotation of the driving wheel 2 drives the shaft rod 21 to rotate.
[0018] Reference Figure 2 As shown, specifically, one end of the shaft 21 is provided with a knocking device 4, which includes a rotating disk 41, the rotating disk 41 is connected to one end of the shaft 21, a traction rod 42 is hinged on the outer surface of the rotating disk 41, and a rocker 43 is hinged on the end of the traction rod 42 away from the rotating disk 41. The shaft 21 rotates to drive the rotating disk 41 to rotate, and the rotating disk 41 drives the traction rod 42 to rotate, so that the traction rod 42 drives one end of the rocker 43 to move up and down, and a support plate 34 is fixedly installed on the outer surface of the support foot 3, and a rotating rod 35 is rotatably connected to the inner side of the support plate 34, and the end of the rotating rod 35 away from the support plate 34 is hinged to the rocker The plate 43 is fixedly connected, a side wall of the support leg 3 is provided with a slide groove 33, the inner wall of the slide groove 33 is slidably connected to the seesaw 43, a No. 1 spring 45 is fixedly connected between the seesaw 43 and the bottom wall of the slide groove 33, and a knocking stick 44 is fixedly installed on the end of the seesaw 43 away from the support plate 34. When one end of the seesaw 43 slides downward along the inner wall of the slide groove 33, it squeezes the No. 1 spring 45. At the same time, due to the limitation of the rotating rod 35 on the support plate 34, the other end of the seesaw 43 is tilted upward. At this time, the other end of the seesaw 43 drives the knocking stick 44 to lift and hit the bottom of the U-shaped groove plate 1.
[0019] Reference Figure 3As shown, in this embodiment: the other end of the shaft 21 is provided with a dredging device 5, and the dredging device 5 includes a half gear 56, and the half gear 56 is fixedly connected to the shaft 21. A limit frame 52 is fixedly installed on the side of the U-shaped groove plate 1 away from the knocking device 4, and a rack 51 is slidably connected inside the limit frame 52. The rotation of the driving wheel 2 can also drive the half gear 56 to rotate, and the rotation of the half gear 56 is meshed with the rack 51. A limit plate 521 is fixedly installed at the bottom of the rack 51, and a second spring 53 is fixedly installed between the limit frame 52 and the limit plate 521. The inner wall of the U-shaped groove plate 1 is slidably connected to the dredging plate 55, and one end of the dredging plate 55 is connected to the limit A traction line 54 is fixedly connected between the plates 521, and the movement of the rack 51 drives the traction line 54 to pull the dredging plate 55 up to the middle section of the U-shaped groove plate 1. When the half gear 56 is not engaged with the rack 51, the rebound force of the second spring 53 causes the rack 51 to quickly reset. At this time, the dredging plate 55 descends to its original position along the inner wall of the U-shaped groove plate 1 by its own gravity, and relies on the rotation of the half gear 56 to engage with the rack 51 to pull the rack 51 and reset the rack 51 when it is not engaged, so that the dredging plate 55 can move repeatedly up and down on the inner wall of the middle and lower sections of the U-shaped groove plate 1, and the half gear 56 and the rack 51 are engaged with each other.
[0020] Working principle: When the staff operates the chute, the angle of the U-shaped trough plate 1 is adjusted by rotating the adjusting bolt 32. When concrete is poured on the U-shaped trough plate 1, the impact force of the concrete causes the driving wheel 2 to rotate, and the rotation of the driving wheel 2 drives the shaft rod 21 to rotate, and the rotation of the shaft rod 21 drives the turntable 41 to rotate, and the turntable 41 drives the traction rod 42 to rotate, so that the traction rod 42 drives one end of the seesaw 43 to move up and down. When one end of the seesaw 43 slides downward along the inner wall of the chute 33, it squeezes the No. 1 spring 45. At the same time, because of the limit of the rotating rod 35 on the support plate 34, the other end of the seesaw 43 is tilted upward. At this time, the other end of the seesaw 43 drives the beating stick 44 to rise and hit the bottom of the U-shaped groove plate 1, so that the upper part of the concrete of the U-shaped groove plate 1 can speed up the flow speed, and it will not stagnate and cause blockage. The rotation of the driving wheel 2 can also drive the half gear 56 to rotate. The rotation of the half gear 56 is meshed with the rack 51, so that the rack 51 slides along the inner wall of the limit frame 52, and the movement of the rack 51 The traction line 54 drives the dredging plate 55 to rise to the middle section of the U-shaped groove plate 1. When the half gear 56 is not meshed with the rack 51, the rebound force of the second spring 53 causes the rack 51 to quickly reset. At this time, the dredging plate 55 descends to its original position along the inner wall of the U-shaped groove plate 1 by its own gravity, and relies on the rotation of the half gear 56 to mesh with the rack 51 to pull the rack 51 and reset the rack 51 when it is not meshed, so that the dredging plate 55 can move up and down repeatedly on the inner wall of the middle and lower section of the U-shaped groove plate 1 , so that the concrete in the middle and lower sections of the U-shaped trough plate 1 will not stagnate and will not cause blockage. The impact force brought by the pouring of concrete allows the driving wheel 2 to serve as a power, and the beating rod 44 repeatedly beats the middle section of the U-shaped trough plate 1 to generate a vibration force to prevent the concrete from stagnation, and the dredging plate 55 repeatedly moves along the inner wall of the middle and lower sections of the U-shaped trough plate 1 to dredge the concrete to prevent stagnation. There is no need to inject other power, which saves energy, has a high degree of automation, and improves the working efficiency and practicality of the chute.
