Description

Technical Field

[0001] The utility model relates to the technical field of stirring type grain dryers, and more particularly to a stirring type grain dryer. Background Art

[0002] In the field of modern agricultural machinery, the stirring grain dryer is an important equipment in the grain processing process. Its drying efficiency and quality are directly related to the storage quality of the grain. However, the stirring grain dryers currently on the market generally adopt a single side wall air intake method. Hot air can only enter the drying cavity through the side wall of the equipment. This traditional air intake method makes it difficult for hot air to penetrate evenly into the grain. Especially in the process of drying large quantities of grain, due to the uneven distribution of hot air, the grain near the side wall is overheated, while the grain in the center area may not be fully dried.

[0003] More importantly, this drying method that relies solely on side wall air intake cannot fully utilize the functional advantages of the stirring blades. Since the stirring blades themselves fail to integrate the air conduction function, the efficiency of hot air conduction in the grain layer is greatly reduced. Even if the stirring blades continuously turn the grains, it is still difficult to ensure that each grain is fully exposed to the hot air at the appropriate temperature. This design limitation not only prolongs the drying time and increases energy consumption, but may also lead to uneven grain drying quality, affecting the storage quality and market value of the grain. At the same time, during the drying process, due to uneven heat distribution, local overheating may also occur, increasing the risk of damage to grain quality. Utility Model Content

[0013] Beneficial effects:

[0014] Compared with the prior art, the present invention provides a stirring type grain dryer with the following beneficial effects:

[0015] 1. The drying mechanism is equipped with a matching structure of a drying shell and a transmission shaft, and multiple drying tubes are arranged inside the transmission shaft. Multiple drying holes are opened on each drying tube, so that hot air can fully contact the inside of the grain. At the same time, by installing a paddle on the drying tube, the grain can be continuously turned over during the drying process, increasing the contact area between the grain and the hot air and ensuring uniform drying effect. The cooperation of the inner nesting and the rotating sleeve ensures the stability of the transmission structure and improves the overall drying efficiency.

[0016] 2. The sealing mechanism realizes the smooth sliding of the intermediate disk by setting an intermediate disk in the rotating sleeve and installing multiple guide strips on the side wall of the intermediate disk to cooperate with the guide grooves on the inner wall of the rotating sleeve. By setting the coaxial cooperation between the sealing rod and the through hole, and combining with the design of the transverse bolts and internal blocks, the intake volume of hot air can be accurately controlled to avoid heat loss, while ensuring the sealing effect and improving the utilization rate of thermal energy.

[0017] 3. The stirring mechanism adopts the transmission mode of motor, belt and pulley. The motor drives the transmission shaft to rotate, so that the paddle can continuously stir the grain. Combined with the design of the feed port and discharge port, the continuous feeding and discharging of grain is realized, so that the entire drying process can be carried out continuously, which improves the work efficiency. At the same time, the stirring process can prevent the grain from agglomerating, ensuring the drying quality. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] In this embodiment, when drying the grain, first rotate the transverse bolt 15 to drive the middle disk 10 to move backward, and then release the connection between the sealing rod 13 and the through hole 14. Since the air intake pipe 17 is connected to the external air intake device, hot air is introduced through the air intake pipe 17 and the through hole 14, and then enters the drive shaft 3 through the rotating sleeve 7, and then the hot air is introduced into the grain through the drying holes 9 on the multiple drying tubes 4.
