つた。 A conventional grain culm conveying chain has a protrusion 2 for feeding grain culms formed on a chain plate 1 as shown in Fig. 1.
The width of the chain plate 1 was determined by a single curve centered on the pin hole 3. However,
In the structure of the grain culm conveying chain in which the chain plates 1 are chained together, the protrusion 2 of the chain moves around the grain culm at the sprocket at the end of the conveying device, making it easy for the grain culm to get caught.As a countermeasure, various guide rods are installed or Entanglement prevention plates, etc. were extended from the sides of the chain. However, none of the above measures are structurally satisfactory because the grain culms are narrowed between the protrusions of the guide rod or entrainment prevention plate and the chain plate, causing them to become stuck or wrapped around each other. It wasn't blooming.

エンを提供するものである。 This idea was made based on the above-mentioned circumstances, and the shape of the conveying chain was changed.The straight part of the grain culm conveying device is no different from the conventional conveying chain, but the sprocket part at the end of the grain culm conveying device is changed. To provide an entrapment-preventing conveyance chain which prevents grain culms from becoming jammed or entwined when carried around.

る。 Here, the grain culm conveyance chain 20 is rotated by the drive wheel 21 at the terminal end, and the conveyed grain culm group A is about to be rolled up by the protrusion 24c at the bending start end of the grain culm conveyance chain 20. is slid down by the smooth rear end of the chain plate 24. Therefore, in the straight section of the grain culm conveying chain 20,
Grain culm group A is the protrusion 24c of the chain plate 24,
However, as the grain culm is further rotated from the bending start end, the projection 24c of the chain plate 24 is covered by the rear end of the chain plate 24 connected to the front, and the grain culm is not transported by the projection 24c. It is released, and the grain culm group A is sequentially slid down.
