Abstract
Description
Technical Field
[0001] This utility model relates to the field of rice processing technology, and in particular to automatic feeding and anti-clogging equipment in rice processing production lines. Background Technology
[0002] As an important food crop, rice processing typically involves multiple stages, including cleaning, impurity removal, hulling, milling, polishing, grading, and packaging. To improve production efficiency and automation in rice processing, modern rice processing lines are generally equipped with automatic feeding and anti-blocking devices. These devices automatically replenish raw materials during processing and prevent blockages during transport or processing, ensuring continuous and stable operation of the production line and improving processing efficiency and product quality.
[0003] Existing feeding and anti-blocking equipment in rice processing production lines typically utilizes a combination of structures such as hoppers, conveying pipes, vibrators, and arch-breaking devices to transport and prevent blockages in the rice raw materials. For example, vibrators or arch-breaking rods are used to prevent rice from forming blockages or bridging within the hopper. Some equipment also utilizes technologies such as screw conveyors and pneumatic conveyors to further optimize material flow and achieve automatic feeding and anti-blocking functions. However, existing technologies still have some shortcomings, lacking effective guiding and pushing mechanisms, resulting in unstable feeding processes and a tendency for rice to accumulate or slip, thus affecting output efficiency. Therefore, this paper proposes an automatic feeding and anti-blocking device for rice processing production lines to address these issues. Utility Model Content
