[0015] The utility model relates to a pouring hopper for double-sealing top block production of a segment mold, which solves the technical problems in the prior art, and the overall idea is as follows:

[0016] Embodiment one:

[0017] Please refer toFigure 1 The pouring hopper for the production of double-sealing top block of segment mold comprises a concrete conveying frame assembly 3 and a plurality of double-sealing top block molds 6 placed on the concrete conveying frame assembly 3, the top of the concrete conveying frame assembly 3 is movably provided with a hopper main frame 1, a hopper is arranged in the hopper main frame 1, a hopper power system 2 is arranged on both sides of the hopper main frame 1, which is used to drive the hopper main frame 1 to move on the concrete conveying frame assembly 3, a discharging opening and closing system 4 is arranged at the bottom of the hopper, and a vibrating discharging system 5 is arranged at the bottom of both sides of the hopper, the hopper power system 2, the discharging opening and closing system 4 and the vibrating discharging system 5 all adopt an electrical control system and are accurately positioned.

[0018] In specific implementation, tracks are arranged on both sides of the top of the concrete conveying frame assembly 3, the hopper power system 2 comprises a motor, a driving gear connected with the output shaft of the motor, roller frames are symmetrically installed on both sides of the hopper main frame 1, rollers are rotatably installed on the roller frames and rollingly fit with the tracks on the top of the concrete conveying frame assembly 3, a driven pulley meshing with the driving gear is installed on one of the roller frames, the driving gear is driven to rotate by the motor, the driven pulley is driven to rotate, and the rollers are driven to rotate, thereby realizing the movement of the hopper main frame 1 on the concrete conveying frame assembly 3.

[0019] In specific implementation, the discharging opening and closing system 4 comprises air cylinders installed on the bottom of the two side walls of the hopper, the piston rod ends of the air cylinders are both connected with a blocking plate, the two blocking plates are oppositely arranged and can be spliced together to block the discharging opening at the bottom of the hopper, when the air cylinders act, the piston rods drive the blocking plates to move, so that the two blocking plates are separated or spliced, thereby realizing the opening and closing of the discharging opening.

[0020] In specific implementation, the vibrating discharging system 5 is a vibrating motor, the vibration frequency and amplitude of which can be appropriately adjusted according to actual production requirements, for different slump of concrete, the parameters of the vibrating motor can be adjusted to achieve the best discharging effect. When the slump of concrete is large, the vibration frequency and amplitude can be appropriately reduced to avoid the segregation of concrete due to excessive vibration; when the slump of concrete is small, the vibration frequency and amplitude can be appropriately increased to enhance the vibration effect on the concrete and ensure the smooth falling of the concrete.

[0021] The detailed connection means is a known technology in the art, and the working principle and process are mainly introduced below, and the specific work is as follows:

[0022] In the pouring hopper work for the segment mould double sealing top block production, first, the hopper main frame 1 is driven by the hopper power system 2 to move on the concrete conveying frame assembly 3. After the motor is started, the motor output shaft drives the driving gear to rotate, the driving gear drives the driven gear to rotate, the driven gear is installed on one side of the roller frame, and then the roller is driven to rotate, the roller rolls along the track on the top of the concrete conveying frame assembly 3, so that the hopper in the hopper main frame 1 can be accurately moved above each double sealing top block mould 6.

[0023] When the hopper main frame 1 moves to the specified position, the discharging opening and closing system 4 starts to work. The cylinder installed at the bottom of the two side walls of the hopper acts, and the piston rod of the cylinder drives the sealing plate to move. When the piston rod is extended, the two sealing plates are separated, the discharge opening at the bottom of the hopper is opened, and the concrete starts to fall into the double sealing top block mould 6 below; when it is needed to stop discharging, the piston rod of the cylinder is retracted, the two sealing plates are spliced together to block the discharge opening, and the falling of the concrete is stopped.

[0024] During the concrete discharging process, the high-frequency vibration generated by the vibration motor of the vibration discharging system 5 plays an important role when working. The vibration is transmitted to the bottom of the two sides of the hopper, and then transmitted to the concrete in the hopper, through the vibration, the internal friction of the concrete can be effectively reduced, the relative movement between the concrete particles is easier, so that the concrete is prevented from accumulating and caking at the bottom of the hopper, the discharge opening is prevented from being blocked, the concrete is promoted to flow out from the discharge opening more smoothly and quickly, and the discharging speed is improved.

[0025] The above description of the embodiments is for the convenience of the ordinary skilled in the art to understand and use the present application, and the person skilled in the art can easily make various modifications to the embodiments, and apply the general principles described herein to other embodiments without creative labor, therefore, the present application is not limited to the above embodiments, the improvements and modifications made by the person skilled in the art without departing from the scope of the present application should be within the protection scope of the present application.
