Auger conveying mechanism for dust or granular material storage and transportation container

Abstract

The auger conveying mechanism of the dust or granular material storage and transportation container disclosed by the present invention comprises a conveying trough arranged at the bottom of the storage and transportation container, an auger assembly arranged in the conveying trough, and a mechanism connecting the storage and transportation container with the conveying trough A strip-shaped slot or several communicating holes arranged in a row, wherein the length direction of the strip-shaped slot or the arrangement direction of the communicating holes is consistent with the transport direction of the auger assembly, and at least one cover plate is provided on the strip-shaped slot or each communicating hole , the cover plate can close or open the bar-shaped groove or communication hole under the action of the control component. In this way, in the actual operation process, the cover plate close to the discharge port can be closed, and the cover plate at the end far away from the discharge port can be opened, so as to avoid the material close to the discharge port in the process of first sending out the material at the end far away from the discharge port. The material exerts pressure on the auger assembly through the strip groove or the communication hole, thereby generating certain resistance to the movement of the auger assembly, so as to improve the conveying efficiency of the auger assembly and save energy.

Description

technical field [0001] The invention relates to a storage and transportation container for storing and transporting dust or granular materials, in particular to an auger conveying mechanism for the storage and transportation container of dust or granular materials. Background technique [0002] The auger conveying mechanism is a common conveying device for conveying dust or granular materials. For containers storing such materials, if the auger conveying mechanism is arranged at the bottom of the container along the length direction of the auger, and the auger is fed through a long through hole or a series of alternately arranged through holes along the length direction of the auger. The conveying pipe communicates with the inner cavity of the storage and transportation container. As disclosed in Chinese patent document CN101164850A, a new type of cement tank with controllable discharge includes a tank body and a screw conveyor at the bottom of the tank body. One end of the...

Problems solved by technology

However, when this type of auger conveying mechanism needs to unload the material, the material at the end far away from the auger outlet will be emptied first, and the other parts of the material will not be discharged obviously. This is because: in the screw of the auger When the rod is rotating, the material entering the spiral groove from the end of the screw rod away from the outlet of the auger moves along the spiral groove toward the outlet; since this part of the material always occupies the spiral groove, the material close to the outlet can hardly enter the spiral groove again. That is to say, the material relatively close to the outlet of the auger can only be unloaded after the material farther away from the outlet of the auger is unloaded; Large pressure, turning these pressures into resistance will consume a lot of energy, and such resistance is constantly changing with the discharge of materials, which also makes the driving source of the screw rod work in an unideal working condition for a long time
