Description

TECHNICAL FIELD

[0001] The utility model relates to heat -resisting component processing equipment technical field, concretely relates to a kind of pouring hopper for producing cover. BACKGROUND

[0002] When producing heat -resisting components such as ladle cover, tundish cover, due to the position of stirring equipment and pouring construction is not in the same place, it needs to use hopper to transfer and pour the high-temperature resistant material slurry stirred into steel structure mold for pouring forming. When using existing hopper to discharge, the operator needs to stand beside the hopper to manually control the flap valve, and use the self-weight of slurry to discharge. Since the weight of slurry is large, it needs to use large force to pry the locking pin of flap valve to open the valve plate. Moreover, after the discharge starts, the valve plate cannot be closed, and it needs to manually lift the valve plate to re-insert the locking pin after the slurry in the hopper is discharged. The pouring operation is more complicated and has poor controllability. At the same time, since the slurry of high-temperature resistant material has adhesion and solidification, if the slurry adhered to the inner wall of the hopper is not cleaned in time after the discharge is completed, it will solidify on the inner wall of the discharge hopper, affecting the use of the hopper. SUMMARY

[0003] The main purpose of the utility model is to overcome the defects in the above background technology, and provide a pouring hopper for producing cover.

[0004] To achieve the above purpose, the pouring hopper for producing cover provided by the utility model comprises a hopper body, a discharging assembly and a scraping assembly.

The discharging assembly is arranged at the discharging port, and the scraping assembly is arranged in the hopper body. The discharging assembly comprises fan-shaped gates and a driving member. Two groups of fan-shaped gates are arranged, and the two side walls of the two groups of fan-shaped gates are rotatably connected to the discharging port through shafts. Gears are coaxially arranged on the shafts, and the two gears on the same side are meshed and connected. The output end of the driving member is connected to the shaft. The scraping assembly comprises a scraping support, a scraping shaft, a scraping plate and a transmission member. The scraping support is fixedly arranged at the top of the hopper body. The scraping shaft is vertically and rotatably connected to the scraping support. The scraping plate is fixedly connected to the scraping shaft through a scraping plate support, and the scraping plate abuts against the inner wall of the hopper body. The scraping shaft is connected to the output end of the driving member through the transmission member. One driving member can drive the fan-shaped gates to rotate to open and close, discharge the high-temperature resistant material stored in the hopper body, or close the high-temperature resistant material. The scraping plate can also be driven to rotate to scrape the high-temperature resistant material residues adhered to the inner wall. Manual control of the flap valve for opening and closing and manual cleaning of the adhered high-temperature resistant material residues are not required, and the work efficiency is effectively improved.

The second transmission shaft is horizontally positioned at the top of the hopper body, with one end meshing with the top of the first transmission shaft via the bevel gears, and the other end meshing with the top of the scraper shaft via the bevel gears. By changing the transmission direction through the bevel gears, transmission can be achieved between the intersecting shafts, eliminating the need for multiple drive motors.

[0007] Further optimization of the technical solution includes a support frame. The hopper body is housed within the support frame, which comprises several vertical and horizontal bars. The vertical bars are vertically fixed around the outer wall of the hopper body, and the two ends of the horizontal bars are fixedly connected to the bottom ends of two adjacent vertical bars. The support frame supports the hopper body off the ground, preventing the bottom of the hopper body from being placed directly on the ground and damaging the bottom discharge assembly.

[0008] To further optimize the technical solution, a first support rod is fixedly connected to the bottom of a set of fan-shaped gate plates, and a second support rod is fixedly connected to the support frame.
