Description

Technical Field

[0001] This utility model relates to the field of building materials equipment, specifically to an automated material transfer system. Background Technology

[0002] Currently, mortar production mainly uses separate conveyor lines to transport main materials and auxiliary materials to a mixing mill for mixing. Since the main and auxiliary materials only begin mixing after entering the mixing mill, there is a lack of pre-mixing. Without prior mixing, the auxiliary materials are difficult to disperse evenly within the mixer, resulting in uneven particle distribution in the mortar mixture. This necessitates longer processing time in the mixer and easily leads to uneven component distribution within the mixed mortar. Furthermore, traditional mixing processes cannot adjust the moisture content of various materials in real time, resulting in unstable moisture content in the mixed mortar and difficulty in controlling the moisture content during the mixing process. Therefore, to solve these problems, an automated material handling system is needed. Utility Model Content

[0009] To better realize this utility model, the auxiliary material feeding device may be further described as follows: the auxiliary material feeding device includes a support frame, a feeding hopper, and a control component. The support frame supports the feeding hopper above the primary transmission device, and the control component is used to adjust the valve opening in the feeding port of the feeding hopper.

The U-shaped conveyor belt cross-section allows auxiliary material particles to be evenly distributed on the surface of the main material. Vibration during transport helps to ensure uniform distribution of the auxiliary material particles. A spraying device is located near the discharge end of the primary conveyor, precisely adding liquid during sand and gravel transport. A mixing drive assembly uses gear pairs to drive the active and driven mixing shafts to work collaboratively. A sampling section is designed in the secondary conveyor for real-time sampling and feedback of the pre-mixed material to the control system, achieving closed-loop control.

The spraying device is located near the outlet end of the primary conveying device 1.
