Description

Technical Field

[0001] The utility model relates to the technical field of concrete pouring, in particular to a pouring mechanism for gangue concrete construction. Background Art

[0002] As an industrial solid waste, coal gangue is a black-gray rock with a low carbon content and harder than coal that accompanies coal seams during the coal-forming process. As one of the industrial waste residues with the largest emissions and the lowest utilization rate, coal gangue is mainly used in construction paving and coal gangue bricks, etc., and its utilization rate is relatively low. However, as a coarse aggregate, it is a good substitute for traditional concrete aggregates, and can save resources and protect the environment.

[0003] When pouring concrete, the traditional pouring method is to set up a pipe bracket and then have workers pour the pipes by hand. This method is more troublesome and increases the labor intensity of workers. At present, since the pouring speed of concrete is difficult to control during the pouring process, the concrete pouring speed is often too fast and the concrete splashes outside the wall, resulting in a waste of concrete.

[0017] Please refer to the attached Figure 1-Figure 4 Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0018] The utility model proposes a pouring mechanism for gangue concrete construction. Before use, the discharge port of the discharge pipe 4 is perpendicular to the handle of the vehicle body 2, the discharge pipe 4 is at the highest position, and the output ends of a pair of electric push rods 6 are in a retracted state. Figure 1As shown, when using the device, first put the mixed coal gangue concrete into the truck bucket 1, and the concrete enters into one end of the discharge pipe 4 through the discharge pipe 3 and the lifting cylinder 5 under the action of gravity, push the car body 2 to the construction site, start a pair of electric push rods 6, the output ends of the pair of electric push rods 6 extend to drive the discharge pipe 4 to slide downward, and the discharge pipe 4 drives the lifting cylinder 5 to slide downward along the discharge pipe 3. When the discharge port of the discharge pipe 4 drops to a position close to the pouring position, close the pair of electric push rods 6, start the motor 1 8, the motor 1 8 drives the worm 7 to rotate, the worm 7 drives the worm gear 10 meshing therewith to rotate, the worm gear 10 drives the discharge pipe 4 to rotate through the pair of electric push rods 6, the discharge pipe 4 drives the lifting cylinder 5 to rotate along the discharge pipe 3, when the angle of the discharge pipe 4 is rotated to an angle suitable for mud discharge, close the motor 1 8, start the motor 2 9, the motor 2 9 drives the spiral blade shaft 11 to rotate along the discharge pipe 4, and the spiral The blade shaft 11 rotates to transport the concrete in the discharge pipe 4 toward the outlet at a uniform speed. The discharge pipe 4 is located close to the pouring position, and cooperates with the spiral blade shaft 11 to keep the concrete discharging at a uniform speed, effectively avoiding the serious problem of concrete splashing during pouring and reducing the loss of concrete. When the device is in use, there is no need to install an additional mud discharge pipe, nor is there any need to manually hold the pipe to pour the concrete. It is more convenient to move and pour, and reduces the labor intensity of manual labor. If the amount of concrete to be poured is greater than the capacity of the bucket 1, the hopper discharge pipe filled with concrete can be clamped and fixed in the bucket 1 of the vehicle body 2 to achieve the purpose of continuous pouring. When the pouring is completed, turn off the motor 2 9, and start a pair of electric push rods 6 again to raise the discharge pipe 4 to avoid collision of the lower discharge pipe 4 when moving the vehicle body 2. After pushing away the vehicle body 2, clean the device to avoid concrete solidification in the device, and restore the device to its initial state.
