Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and in particular to a grain dryer. Background Technology

[0002] Grain is an organic organism, and moisture is essential for its survival. However, excessive moisture can induce the growth of insects and microorganisms, easily causing grain to heat up, ferment, spoil, and reduce germination rates. Currently, the main methods for controlling grain moisture content are natural sun-drying and drying with grain dryers. Natural sun-drying is easily affected by weather and space constraints. In major grain-producing areas, due to large yields and insufficient drying space, grain purchased by grain depots often has a moisture content exceeding the safe level, which is a major factor leading to mold growth, especially during periods of continuous overcast weather when grain is being purchased. Furthermore, even if the moisture content of the grain does not exceed the safe level when it enters the warehouse, natural re-dampening necessitates regular sun-drying to prevent mold growth.

[0003] According to Chinese Patent Publication No. CN112484440A, a grain dryer is disclosed, relating to the field of agricultural machinery technology. It includes a mounting plate, a support frame fixedly mounted on the upper part of the mounting plate, a drying chamber mounted on the upper part of the support frame, a feed inlet at the top of the drying chamber, a sealing cover at the top of the feed inlet, a fixed frame mounted at the left opening of the drying chamber, and a rotating shaft mounted on the right side of the fixed frame via a bearing. A first pulley is mounted on the right end of the rotating shaft, passing through the drying chamber. A motor is also mounted on the mounting plate, and a second pulley is mounted on one end of the motor's right output shaft. The first and second pulleys are connected by a belt drive. Fixed rods are evenly spaced on the outer wall of the rotating shaft, and stirring blades are mounted on the other end of the fixed rods. A hot air duct is mounted on the upper right side of the drying chamber, and an exhaust fan is mounted on the left side of the support frame. Its structure is relatively simple, with low manufacturing and operating costs, while ensuring drying efficiency.

[0004] The aforementioned patent has the advantages of a relatively simple structure and low manufacturing and usage costs. However, the overall drying effect is not complete, and there are more blind spots. Furthermore, the adjustment method of the overall device is not flexible and convenient enough.
