Description

Technical Field

[0001] The utility model relates to the technical field of conveying hoppers, in particular to a cement conveying hopper. Background Art

[0002] Cement is a powdery hydraulic inorganic gelling material. Cement becomes a slurry after being mixed with water. It can harden in the air or better in water, and can firmly bond sand, stone and other materials together. After hardening, cement not only has high strength, but also can resist the erosion of fresh water or salt water. For a long time, cement, as an important gelling material, has been widely used in civil engineering, water conservancy, national defense and other projects. The production process of cement mainly consists of limestone crushing, screening, raw material preparation and homogenization, preheating and decomposition, uniform mixing, cement clinker burning and cement grinding and packaging.

[0003] The existing Chinese utility model patent with reference announcement number CN216470724U discloses a cement conveying hopper, which can drive the rotation of the rotating shaft through the forward and reverse motors, so that the driving gear installed on the outer wall of the rotating shaft can rotate synchronously with the rotation of the rotating shaft, so that the driven gear meshing on the top of the driving gear can also rotate accordingly. At this time, the screw installed in the inner wall of the driven gear will rotate in the same side direction as the driven gear rotates, so that the ball nut sleeve threaded on the outer wall of the screw can move back and forth horizontally on the outer wall of the screw as the screw rotates. At this time, the fixed frame installed on the top of the ball nut sleeve can also move back and forth horizontally on the bottom surface of the filter plate, so that the bristles of the cleaning brush plate itself can clean the impurities and particulate matter attached to the filter holes, thereby ensuring the filtering effect of the filter plate on impurities and particulate matter in cement, thereby increasing the cement conveying capacity.

[0004] When the above-mentioned cement conveying hopper is in use, its upper part is in an open state. When the external sunlight is strong, it is easy to cause direct sunlight to solidify the cement inside, affecting the normal use of the cement. In addition, it is not convenient to discharge the material evenly during discharge, which may cause discharge blockage. Therefore, those skilled in the art provide a cement conveying hopper to solve the problems raised in the above-mentioned background technology. Utility Model Content
