Description

Technical Field

[0001] The utility model relates to the technical field of material chute devices, in particular to a material chute device for cement production. Background Art

[0002] Cement is a powdery, hydraulic, inorganic cementitious material. After adding water and stirring, it becomes a slurry, which can harden in the air or in water, and can firmly bond materials such as sand and stone together. The early mixture of lime and volcanic ash is very similar to modern lime volcanic ash cement. It is used to bond concrete made of crushed stone. After hardening, it not only has high strength, but also can resist the erosion of fresh water or salt water. For a long time, it has been widely used in civil engineering, water conservancy and other projects as an important cementitious material.

[0003] When cement passes through the feeding chute, due to the different environments, the cement will clump and other phenomena, which will affect the use. The existing feeding chute device cannot effectively deal with the caking of cement, which affects the quality of cement production. Based on the above problems, we provide a cement production feeding chute device. Utility Model Content

[0006] The utility model is further configured that a second servo motor is bolted to the lower portion of the back side of the slot body, and the rear portion of the rotating rod passes through the slot body and is bolted to the output end of the second servo motor.

[0007] By adopting the above technical solution, the second servo motor can be used as a driving source to drive the rotating rod to rotate in the inner cavity of the slot body.

[0008] The utility model is further configured that a feed hopper is bolted to the upper portion of the left side of the trough body, and a discharge pipe is connected to the center of the bottom of the trough body.
