Description

Technical Field

[0001] The utility model belongs to the technical field of material conveying, and in particular relates to a material conveying mechanism. Background Art

[0002] Application No. 202321081503.7 provides a multifunctional material conveying mechanism. Driven by a motor, the conveyor belt can drive the raw materials to move. When the raw materials are transported to the bottom of the conveyor belt, the scraper plate can drive the raw materials to continue to move, so that the raw materials can be conveniently transported to the designated position; through the rotation of the rotating shaft, the toggle plate is driven to lift one end of the cross bar, so that the knocking hammer at the other end is away from the screen plate. When the toggle plate is separated from the cross bar, the knocking hammer hits the screen plate under the pull of the spring, so that the screen plate can vibrate. When the raw materials pass through the screen plate, the raw materials can be screened, thereby, screening can be achieved during the transportation of the raw materials;

[0003] However, the material is transported between the two scraper plates. When the material moves to the top of the screen plate, the material that meets the screening conditions is easily on top of the material that does not meet the screening conditions, causing the material that meets the screening conditions to be transported backward along the scraper plates, and the material that meets the screening conditions is discharged through the discharge port, resulting in inaccurate material screening, affecting the subsequent use of the material, and poor practicality.
