The present invention relates to a grain bagging device that includes a bag storage section on the proximal end side of each of the left and right pair of bag support rods, and further includes a grain filling location on the tip side of the bag support rod.

[Conventional technology]

In the above-mentioned grain bagging device, conventionally, as shown in Japanese Patent Publication No. 48-38958, a feeding body that feeds out a bag from a bag storage section of a bag support rod to the tip side is freely rotatable to the side of the bag support rod. In addition, an opening for opening the bag from the feeding body is rotatably provided above the tip of the bag support rod, thereby making it possible to automatically take out and open the bag.

[Problem to be solved by the invention]

In the conventional case, a separate device for bag removal and a device for bag opening were required, making the entire bag filling device large and complicated in structure.

An object of the present invention is to enable automatic bag removal and automatic opening while reducing the size of the device and simplifying the structure.

[Means to solve the problem]

The present invention is characterized in that, in the above-mentioned grain bagging device, (a) each of the bag support rods is attached so as to be rotatable around the rod axis, and the bag support rods are attached from the bag storage section to the bag support rods; A threaded portion for locking and transferring the bag is provided on the tip end side of the rod, and the direction of the slope of the bag transferring lead of the threaded portion is formed to be the same on the left and right sides.

[B] The bag is provided with an opening tool at each of the left and right ends of the opening.

[c] The opening tool is provided integrally with an eyelet through which the bag support rod is inserted, and with respect to the eyelet,
It also includes an opening operation piece extending toward the center in the bag width direction.

[d] The opening operation piece is provided on the inner surface side of the opening edge of the bag, and the opening operation pieces are provided on one inner side of the front opening edge and the back opening edge, which are reversed from each other. It's in being. The functions and effects thereof are as follows.

[Effect]

When the bag support rod is driven, it causes a rotating threaded portion to transfer the bag from the bag storage section to the distal end side. When the bag is sent to the grain filling location on the tip side of the bag support rod, the eyelet of one opening tool engages with the threaded part, and its posture is regulated in the direction of the lead inclination of that threaded part. . Then, the opening operation piece that is integrated with the eyelet is restricted in the reed inclination direction, so the front opening edge or back opening edge where this opening operation piece is provided takes a posture along the reed inclination direction, and the opening The back side opening edge or the front side opening edge where no operating piece is provided maintains a posture substantially perpendicular to the rod axis. Then, the front opening edge and the back opening edge are separated from each other. This separation of the front and back opening edges occurs at both ends of the bag opening, and as a result, the bag is in an open state.
In other words, just by driving the bag support rod, the threaded part rotates and acts, and the left and right opening tools are tilted and operated by the threaded part, and the bag is automatically opened. be.

〔Effect of the invention〕

By using the bag support rod as the member for opening the bag, all you need to do is modify the bag support rod to a drive rotation type and add a screw part and an opening tool, making it smaller and more structured than before. It is easy to make and installation is advantageous both in terms of space and economy.

Moreover, the opening of the bag mouth can now be made properly due to the action of the opening tool and the threaded portion.
