Description

Technical Field

[0001] The utility model relates to the technical field of grain drying, in particular to a grain drying device with a dust removal mechanism. Background Art

[0002] With the rapid development of the national economy, people have put forward higher requirements on the taste and quality of grain, especially for the rice made from finished rice, which is required to have a smooth appearance, a fragrant smell, and moderate softness and hardness. If the grain is dried by traditional methods such as turning it over and drying it on the road, the quality of the grain cannot be guaranteed. At present, most of the grain is dried in a drying tower, thus ensuring the quality and taste of the grain.

[0003] When using the existing drying tower, it is difficult to scrape off the grain attached to the bottom surface and inner wall of the tower body, which is not only not conducive to the rapid drying of the grain, but also easily causes grain waste. Moreover, when the grain is poured into the drying tower, a large amount of dust will be generated. The existing drying tower lacks a corresponding dust removal mechanism to effectively remove the dust.

[0004] The prior art discloses a patent with a publication number of CN215113683U. In this solution, a motor is fixedly connected to the interior of the fixed seat. The driving end of the motor movably penetrates the bottom of the fixed seat and the top of the tower body and is connected to a rotating shaft. A stirring rod is fixedly connected to both sides of the rotating shaft. A cleaning mechanism is installed at the bottom of the rotating shaft, and a dust removal mechanism is sleeved on the exterior of the tower body. The cleaning mechanism can scrape off the grain attached to the bottom surface and inner wall of the tower body, allowing the grain to roll quickly, which is conducive to rapid drying of the grain. This not only reduces grain waste, but also improves the drying efficiency of the grain at the bottom of the tower body. The dust removal mechanism can suck in the dust in the tower body and attach it to the sponge pad, thereby achieving the purpose of dust removal. In addition, the sealing cover is easy to disassemble and assemble, making it convenient to replace and clean the sponge pad in the threaded tube.

[0005] As the existing devices are used, the shortcomings of the existing technology are gradually exposed, which are mainly manifested in the following aspects:
