Detailed Description of the Invention [Industrial Application Field] The present invention provides a bag storage section for storing grain bags suspended from the proximal end of a bag support rod, and also provides a bag storage section for storing grain bags suspended from the bag support rod. The present invention relates to a structure of a bag take-out portion of a grain bagging device, in which the bag support rod is provided with a spiral portion that locks and transfers a grain bag on the tip side of the rod.

[Conventional technology]

Conventionally, in the above-mentioned grain bagging apparatus, the engaged state of the grain bag and the helical portion has been maintained only by the grain bag's own weight.

[Problem to be solved by the invention]

Conventionally, when a bag is taken out by a spiral part, the grain bag floats up from the bag support rod due to vibrations caused by the rotation of the spiral part, and the bag part that should be located between the spiral parts ends up on the spiral part. There were cases in which the feeder was stuck or moved to another location between the spiral parts, making feeding impossible, or causing a transfer error that caused a difference in the left and right feed strokes.

An object of the present invention is to make transfer errors less likely to occur.

[Means to solve the problem]

The present invention is characterized by the fact that the above-mentioned structure of the bag take-out portion of the grain bagging device is provided with a bag presser for suppressing the lifting of the grain bag from the bag support rod. , its functions and effects are as follows.

[Effect]

By suppressing the lifting of the grain bag from the bag support rod, the bag portion where the spiral portion transfers is prevented from coming off from between the spiral portions, and the bag portion rides on the spiral portion. Movement to other locations between spiral portions can be prevented.

〔Effect of the invention〕

Due to the action of the bag presser, the above-mentioned transfer errors due to the bag portion riding up or moving are less likely to occur, and the bag can be taken out accurately and smoothly.
