Description

TECHNICAL FIELD

[0001] The utility model relates to a grain drying tower that uniformly feeds grain. BACKGROUND

[0002] The grain drying tower is an industrial equipment for drying grain. A grain drying tower feeding mechanism is disclosed in Chinese patent No. 202221316663.0, which includes a grain distribution box. A grain inlet is arranged at the top of the grain distribution box, and a grain outlet is arranged at the bottom of the grain distribution box. One of the grain outlets is provided with a first grain distribution branch pipe, and the other grain outlet is provided with a second grain distribution branch pipe. The distance between the grain outlets of the first and second grain distribution branch pipes is greater than the distance between the grain inlets, so as to scatter the falling grain to the two sides of the length direction of the grain storage part of the drying tower. The grain drying tower feeding mechanism can scatter the falling grain to the two sides of the length direction of the grain storage part of the drying tower through the first and second grain distribution branch pipes, so that the grain can fall on the two sides, thereby maximizing the distribution area of the grain in the grain storage part of the drying tower and avoiding the lack of grain on the two sides of the tower. However, the grain feeding mechanism scatters the grain to the two sides of the drying tower with a rectangular cross section through the first and second grain distribution branch pipes to meet the requirement of uniform grain feeding of the drying tower with a rectangular cross section. It is not suitable for the drying tower with a square or circular cross section, which may cause the lack of grain in the local area without the grain distribution branch pipe. SUMMARY
