Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is directed to a pair of left and right bag support rods that hang and support a grain bag, and drive a spiral portion that locks and transfers the grain bag on the tip side thereof. The present invention relates to a bag support structure of a grain bagging device, which is provided with a mechanism capable of being driven and rotated freely, and is provided with a grain filling boot that can be raised and lowered to fit into the opening of a grain bag that is suspended and supported.

[Conventional technology]

Conventionally, in the above-mentioned grain bagging apparatus, the left and right bag support rods have been fixed in a parallel state, resulting in the following disadvantages.

[Problem to be solved by the invention]

In other words, if the spacing between the support rods is set so that the helical portion of the bag support rod and the bag portion on which it acts are well engaged so that they do not come off, and the bag is transferred with high accuracy by the helical portion, the grain bags will be When the bag is transferred to and supported by the tip of the support rod, the gap between the support rods makes it difficult to open the filling port of the bag, making it difficult to lower and insert the filling boot of the bagging hopper into the grain bag.

SUMMARY OF THE INVENTION An object of the present invention is to enable the bag to be transferred with high accuracy using the spiral portion, and to facilitate the opening of the bag transferred to the tip end side of the support rod.

[Means to solve the problem]

A characteristic configuration of the present invention is that in the bag support structure of the grain bagging device described above, at least one of the bag supports is arranged in a state in which the distance between the tip sides of the bag support rods changes in the width direction of the grain bag. The rod is mounted so as to be swingable in the horizontal direction about the vertical axis, and a spring is provided on the side where the gap between the leading ends widens to swing the bag support rod. The functions and effects thereof are as follows.

[Effect]

The bag supporting rod spacing at which the spiral portion and the grain bag can be satisfactorily engaged is revealed by the rocking bias of the spring, so that the bag transfer by the spiral portion can be carried out with high precision.
However, when an operating force is applied, such as by installing and activating a support rod, the spring is elastically deformed, and the distance between the support rod tips becomes narrower than the bag support rod distance, and both sides of the grain bag are By coming together, the filling port can be opened wide.

〔Effect of the invention〕

Due to the rocking bias of the bag support rod, the bag can be transferred with high precision, and the filling port can be opened easily or widened by bringing both sides of the grain bag together. It was possible to insert the filling port boot into the bag securely and fully, thereby making it possible to efficiently fill the grain.
