Description

Technical Field

[0001] This utility model belongs to the technical field of grain processing equipment, specifically a feeding device for a grain dryer. Background Technology

[0002] Grain drying is an important step after grain harvesting and a crucial condition for the safe storage of grain through the summer. Existing grain dryers generate a significant amount of dust during the drying process. When this dust is also being dried inside the machine, it can negatively impact the taste of the grain. Directly expelling the dust from the outside of the machine would harm the environment, and cleaning the dust inside the machine is extremely inconvenient.

[0003] Existing grain dryers use a screw feeder to feed the grain into the dryer for drying. Since there is no grain cleaning device, when grain cleaning is required, an additional grain cleaning machine needs to be purchased, which increases the operating cost. Without purchasing an additional grain cleaning machine, grain mixed with waste such as stones and straw cannot be cleaned. The waste in the grain can easily cause wear and tear on the equipment and affect its service life. Utility Model Content
