Abstract
Description
Technical Field
[0001] The present application relates to the technical field of chutes, and in particular to a splash-proof chute for concrete pouring. Background Art
[0002] In the construction process of some foundation construction surfaces, concrete pouring is often required. The concrete is mixed by a mixer truck and then discharged. Due to the large height difference between the concrete discharge position of the mixer truck and the mold entry position of the concrete foundation construction surface, direct pouring is not possible, so a chute is needed to pour the concrete.
[0003] In the case of a large height difference, the concrete flows too fast in the chute. When the concrete falls into the target position, the large height difference will cause the concrete to splash everywhere. After the operation is completed, the splashed concrete requires a lot of manpower, physical and time to clean up. Utility Model Content

[0015] By adopting the above technical solution, when the telescopic cylinder adjusts the angle between the slow flow plate and the inner wall of the slow flow section by extending or retracting its own piston rod, the slider slides along the guide rod in the slide groove, so that the piston rod of the telescopic cylinder will not be stuck during movement.
[0016] Optionally, the end of the telescopic cylinder piston rod is ball-jointed to the slider.
[0017] By adopting the above technical solution, the angle between the telescopic oil cylinder piston rod and the sliding block is flexible, so that the telescopic oil cylinder piston rod moves smoothly.
[0018] Optionally, a through slot is provided in the sliding block for the guide rod to pass through, and the sliding block is ball-jointed with a ball in the sliding slot.
[0019] By adopting the above technical solution, the sliding friction between the slider and the guide rod is replaced by rolling friction, thereby reducing the friction between the slider and the guide rod, thereby making the slider move smoothly.

DETAILED DESCRIPTION
[0032] The following is combined with Figure 1-4 This application is described in further detail.
[0033] The embodiment of the present application discloses a splash-proof chute for concrete pouring.
[0034] refer to Figure 1A splash-proof chute for concrete pouring includes a chute body 1, which includes a slow flow section 11 and a discharge section 12. The slow flow section 11 and the discharge section 12 are both arranged along an inclined direction, and the inclination angle of the discharge section 12 is greater than the inclination angle of the slow flow section 11. A slow flow component 3 is arranged in the slow flow section 11, and a splash-proof cover 2 is provided on the discharge section 12, which is fixed to the discharge section 12.
[0035] After the concrete enters the tank body 1, the kinetic energy of the concrete is reduced after being buffered by the slow flow component 3, thereby reducing the splashing of the concrete. Then the concrete enters the discharge section 12, and the splashing is further reduced by the splash shield 2, and finally the concrete falls into the target position.
[0036] refer to Figure 1 The slow flow assembly 3 includes a plurality of slow flow plates 31, and the plurality of slow flow plates 31 are distributed in two rows. The two rows of slow flow plates 31 are respectively arranged on both sides of the slow flow section 11, and the slow flow plates 31 in the two rows are aligned one by one. The length of each row of slow flow plates 31 increases successively along the inclined direction of the slow flow section 11, and one end of the slow flow plate 31 is rotatably connected to the inner bottom wall of the slow flow section 11.
[0037] refer to Figure 2 and Figure 3 A slide groove 313 is provided on the side wall of one side of the slow flow plate 31, and a slider 314 is slidably connected in the slide groove 313. A guide rod 315 is fixedly connected to the slow flow plate 31 in the slide groove 313. The guide rod 315 passes through the slider 314 and the two are slidably adapted. A through groove 3141 is penetrated in the slider 314 for the guide rod 315 to pass through. The slider 314 is ball-hinged with a ball 3142 in the slide groove 313, and the ball 3142 abuts against the outer wall of the guide rod 315.
[0038] refer to Figure 1 and Figure 2 The slow flow assembly 3 also includes a telescopic cylinder 32. The number of the telescopic cylinders 32 is the same as the number of the slow flow plates 31 and corresponds one to one. The piston rod end of the telescopic cylinder 32 is ball-jointed with the slider 314. The telescopic cylinder 32 is installed on the slow flow section 11, and the telescopic cylinder 32 is installed on the side of the slow flow plate 31 facing the slide groove 313.
[0039] refer to Figure 1 A first baffle 311 and a second baffle 312 are fixedly connected to one side of the slow flow plate 31 facing the telescopic cylinder 32. The first baffle 311 and the second baffle 312 are integrally formed, and an outer wall of the slow flow section 11 is provided with an avoidance groove 111 for allowing the first baffle 311 and the second baffle 312 to move.
[0040] The telescopic cylinder 32 is started to drive its own piston rod to extend or retract. The movement of the piston rod of the telescopic cylinder 32 drives the slider 314 to slide along the guide rod 315 in the slide groove 313. At the same time, the piston rod of the telescopic cylinder 32 drives the slow flow plate 31 to rotate, thereby adjusting the angle between the slow flow plate 31 and the inner wall of the slow flow section 11; during the movement of the slow flow plate 31, the slow flow plate 31 drives the first baffle plate 311 and the second baffle plate 312 to slide in the avoidance groove 111. During the pouring operation, the first baffle plate 311 and the second baffle plate 312 prevent concrete from falling easily onto the surface of the telescopic cylinder 32; during the movement of the slider 314, the slider 314 drives the ball 3142 to roll along the guide rod 315, thereby reducing the friction between the slider 314 and the guide rod 315.
[0041] After adjusting the angle between the slow flow plate 31 and the inner wall of the slow flow section 11 to the required angle, the pouring operation is started. After the concrete enters the slow flow section 11 , it is intercepted by the slow flow plate 31 , thereby reducing the kinetic energy of the concrete when it enters the discharge section 12 .
[0042] refer to Figure 1 and Figure 4 An inspection port 316 is provided through the outer wall of the slow flow section 11. The number of the inspection ports 316 is the same as the number of the telescopic cylinders 32 and corresponds one to one. The inspection port 316 is covered with a door panel 317. The top of the door panel 317 is hinged to the slow flow section 11. A torsion spring 318 is installed at the hinge between the door panel 317 and the slow flow section 11. The bottom of the door panel 317 is fixedly connected to a limit plate 3171, and the limit plate 3171 and the slow flow section 11 are fixed by bolts.
[0043] After the staff removes the bolts, the torsion spring 318 releases its elastic force to drive the door panel 317 to rotate, thereby opening the inspection port 316, thereby exposing the telescopic cylinder 32 to the field of vision of the maintenance personnel, making it easier for the maintenance personnel to inspect and replace it.
[0044] The implementation principle of the splash-proof chute for concrete pouring in the embodiment of the present application is as follows: the telescopic oil cylinder 32 is started to drive the slow flow plate 31 to rotate through the slider 314, thereby adjusting the angle between the slow flow plate 31 and the inner wall of the slow flow section 11, and the pouring operation is started after the angle between the slow flow plate 31 and the inner wall of the slow flow section 11 is adjusted to the required angle. After the concrete enters the slow flow section 11, the slow flow plate 31 intercepts it, thereby reducing the kinetic energy of the concrete when it enters the discharge section 12; at the same time, after the concrete enters the discharge section 12, the splash-proof cover 2 plays a protective role to reduce the concrete from splashing to the outside. Through the above structure, the effect of reducing the splashing of concrete is achieved.
[0045] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
