Description

Technical Field

[0001] The utility model relates to the technical field of alumina powder feeding, in particular to an alumina powder bag dumping device. Background Art

[0002] Currently, when feeding alumina powder into a silo, workers usually pour bags of alumina powder into the silo from the top, which not only increases the labor intensity of the workers but also reduces the feeding efficiency.

[0003] In order to reduce the labor intensity of workers, a flippable hopper is set on the loading platform. Workers place the alumina powder bag in the hopper and pour the alumina powder by flipping the hopper. Although this reduces the labor intensity of workers to a certain extent, more than two workers are still required to hold the two corners of the alumina powder bag during the flipping process of the hopper to prevent the alumina powder bag from slipping, and efficiency cannot be improved. Summary of the Invention

[0006] As a preferred technical solution of the present invention, the shape of the strip groove is an inverted trapezoidal structure, and the shape of the pressure plate is adapted to the shape of the strip groove.

[0007] As a preferred technical solution of the present invention, the distance from the strip groove to the hopper opening is greater than the length of the alumina powder bag.

[0008] As an optimal technical solution of the present utility model, the driving flipping mechanism includes a first hydraulic telescopic rod and a support, the fixed end of the first hydraulic telescopic rod is connected to the side of the support bar, the support bar is fixed on the upper surface of the loading platform, the support is fixed on the lower surface of the hopper, and the telescopic end of the first hydraulic telescopic rod is hinged to the support.

[0009] As an optimal technical solution of the present invention, two bases are symmetrically arranged on the upper surface of the support bar, each base is composed of two fixed blocks and a rotating shaft, the two ends of the rotating shaft are respectively rotatably connected to the fixed blocks, and a connecting rod is fixed to the bottom of the hopper, and the connecting rod is fixedly connected to the rotating shaft.

[0010] Compared with the prior art, the beneficial effects of the utility model are: the alumina powder bag dumping device is reasonably designed and ingeniously conceived. By setting a strip groove at the inner bottom of the hopper, when the alumina powder bag is placed, the extra bag body at the tail is located at the upper end of the strip groove, and then the second hydraulic telescopic rod pushes the pressure plate down to press the extra bag body into the strip groove. During the flipping process of the alumina powder bag, there is no need for workers to fix the bag body, which greatly reduces the labor intensity of the workers and improves the loading efficiency.
