Description

TECHNICAL FIELD

[0001] The utility model relates to mechanical technical field, concretely is a kind of small granular grain conveying device. BACKGROUND

[0002] Grain refers to the seed of plant that can obtain starch and is suitable for food (such as wheat, corn and rice); also refers to the seed of seed or food plant produced. Grain can be used as staple food in daily life, and can play the role of satiety, in addition to this, grain is also good for human health.

[0003] Most of the grains are in the form of particles, which need to be conveyed by a conveying device during processing. However, since most of the grains are small in size, the grains are prone to sliding along the conveying belt during the conveying process by the traditional belt conveyor, which results in the inability to efficiently convey the grains. Even if some conveying belts are provided with blocks to prevent the grains from sliding, the position where the conveying belt contacts the transmission roller will present a curved arc structure. When the blocks are fixedly bonded to the conveying belt, the arc structure will cause the position where the blocks are connected to the conveying belt to separate, thereby causing the blocks to easily fall off. When the blocks are movably embedded in the conveying belt, the arc structure will cause a gap between the blocks and the conveying belt, and the small particles of the grains will fall into the gap.
