Abstract

PURPOSE:To eliminate the possibility of a roll silage being deteriorated rapidly, by inserting a folding opening frame into a soft bag, unfolding the same to open the bag so as to be packed with the roll silage, connecting an air suction machine with the bag to temporarily close the opening thereof and permanently closing this opening after the air in the bag has been evacuated by operating an air suction machine. CONSTITUTION:After inserting a folded opening frame 1 into a bag 2, said frame 1 is unfolded into a circular shape by spreading out the opening frame 1 with an operation rod 4 being held by hand. The bag is thereafter packed with a roll silage (r) to the full by a self-propelled packing machine, while a suction hose 303 of an air suction machine 3 is inserted into the bag 2 for connection therewith and a bag opening is temporarily closed with a fastening means 7. The bag 2 is then evacuated by the air suction machine to be reduced in volume. Upon the formation of a vacuum of the bag 2, the area of the bag 2 near the roll silage (r) is permanently closed with the fastening means. The bag 2 thus kept at a vacuum prevents the deterioration of the roll silage packed therein and is also more convenient to handle due to a reduction in the volume thereof.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application - The present invention relates to an improvement in the method of stuffing rolled silage (dried grass clippings into rolls) into flexible stuffing bags.

Prior Art A thin, flexible stuffing bag is manually opened and fitted into a circular mouth frame fixed to a movable frame with wheels, and after the rolled silage is packed, it is removed from the circular mouth frame and the inside of the stuffing bag is removed. The mouth is tightened without letting the air out.

Problems to be Solved by the Invention In the prior art, thin and flexible stuffing bags are opened by hand, which makes it difficult to perform the opening operation efficiently.

In particular, in most cases, the stuffing bag is tightly attached, so it must be opened by peeling it off by hand, which makes the tearing process time-consuming and the opening process even more inefficient. After bagging roll silage, when removing the stuffing bag from the circular mouth frame, the opening of the stuffing bag is in close contact with the circular mouth frame, so the opening of the stuffing bag should be removed from the circular mouth frame. The bag must be removed while being peeled off, and this tearing and removing operation is time consuming and inefficient, and there is a risk that the bag may be torn during this removal operation. Furthermore, since the air inside the stuffing bag filled with rolled silage is not vented,
There is a risk that the rolled silage during storage will deteriorate rapidly due to the air inside the bag, and the air inside the bag will expand and become bulky, making it inconvenient to transport and store. There is a risk of it easily bursting due to an unexpected accident.

The present invention has been made in view of the above circumstances, and by expanding the opening frame which can be folded and expanded freely, it is possible to quickly and easily open a thin and flexible stuffing bag. By folding the opening frame, the stuffing bag can be closed quickly and easily, and furthermore, the risk of the roll silage stuffed in the stuffing bag deteriorating quickly is eliminated, and it is easy to handle. The purpose of the present invention is to propose an excellent and convenient method for packaging silage.

Means for Solving the Problems The means achieved by the present invention to achieve the above object is to fold a mouth frame that can be folded and expanded, insert it into a flexible stuffing bag, and then expand it. After opening the stuffing bag and stuffing rolled silage into the opened stuffing bag, connect an air suction device to the stuffing bag and temporarily tighten it, and operate the air suction machine to remove the air inside the stuffing bag. This means tightening the pickled water opening.

After the working opening frame is folded and inserted into the stuffing bag, it is expanded and the stuffing bag is opened, so that the stuffing bag opens wide and roll silage can be easily stuffed. Then, I connected an air suction machine to the stuffing bag filled with roll silage and temporarily closed it.
The air suction machine becomes difficult to detach from the stuffing bag after starting operation.

Furthermore, since the air inside the stuffing bag filled with rolled silage is removed and the graft opening is tightened, the inside of the bag is vacuumed and the bulk is reduced.

Explaining the structure of each member and the packing means in the order of the drawings of the embodiment, the mouth frame (1) has a pair of semicircular frame rods (101) with both ends mutually connected as shown in the first and second drawings. It is configured so that it can be pivoted and folded and expanded.

A pair of semicircular frame rods (101) constituting the mouth frame (1) are
The frame rods (101) are configured to have a circular cross section, and both ends of the frame rods are formed into a flat crushed shape, and the flat portions are pivotally connected to each other. (4) are provided oppositely and protrudingly, and are constructed so that folding and unfolding operations can be performed by grasping their operating levers.

The reason why the semicircular frame rod (101) has a circular cross-sectional shape is that the opening frame (1) does not close to the stuffing bag (
2) This is to prevent the stuffing bag from getting caught, and to prevent damage such as perforation or tearing of the stuffing bag. The mouth frame (1) has a semicircular shape when folded, and a perfect circle when expanded. The stuffing bag (2) is a thin, flexible, air-impermeable and moisture-impermeable bag made of soft vinyl or other materials, and is a well-known structure.

The air suction machine (3) has a structure that sucks in air from one side and exhausts it from the other side like a vacuum cleaner, and has a rotatable fan (302) inside the machine box (301), and Suction hoses (303) are installed on both sides of the machine box (301).
) and an exhaust hose (304). The air suction machine (3) is connected by inserting the suction hose (303) into the stuffing bag (2) filled with roll silage, and placing the exhaust hose (304) outside the stuffing bag (2). do. The air suction machine (3) is powered by the engine (1) of the tractor (1).
In order to determine
The pulley (601) is connected with a belt or chain and attached to the transmission shaft of the 27th pulley.
(6) The first pinion pulley (602) for the fan (
A belt hook or chain hook is connected to the second binion pulley (305) of the input shaft of the tractor (302).
When the engine of 1) is started, the fan (302) rotates at an increased speed to suck the air inside the stuffing bag (2) and exhaust it.

Next, the means for packing roll silage will be explained.

First, two workers facing each other insert the folded opening frame (1) into the stuffing bag (2), grip the operating lever (4), and hold the opening frame (
1) Expand it into a perfect circle (Figure 1).

The stuffing bag (2) has a large, perfectly circular opening when the opening frame (1) is expanded (see Fig. 2). When the stuffing bag (2) is opened, roll silage (R) is stuffed to the depths inside the bag using a self-adjusting stuffing machine (well-known stuffing machine, not shown) (not shown), and then an air suction machine ( 3) The suction hose (303) is stuffed into a bag (
2) Connect the air suction device (3) to the stuffing bag (2) by inserting it into the stuffing bag (2), and attach the stuffing bag (2) to the suction hose ( 303), while connecting the air suction machine (3) to the output shaft (t') of the engine of the tractor (1) via the speed increaser 1 (6) (see Fig. 3). Then, when the engine of the tractor (1) is started, the fan (3) of the air suction machine (3)
02) is rotated at increased speed by the speed increaser (6), and the stuffing bag (2
) The air inside is removed and a vacuum is created, reducing the bulk. Once the air inside the stuffing bag (2) has been removed, tighten the main opening of the stuffing bag (2) near the rolled silage (r) with the same fastener (not shown) as above, and release the temporary opening. and the suction hose (3
03) from the stuffing bag (2). The stuffing bag (2) that has been evacuated in this way has a vacuum inside, which prevents deterioration of the stuffed roll silage, and at the same time reduces the bulk, making it easier to handle.

In addition, when tightening the main opening of the stuffing bag (2), if the fastener (7) used for temporary closing is an elastic band, use the suction hose (303).
After pulling it out from the stuffing bag (2), the fastener (7) may be automatically deflated and the main end may be tightened as is.

Effects of the Invention In the present invention, as described above, the stuffing bag that has been folded and inserted into the stuffing bag is expanded and the stuffing bag is opened, so that the stuffing bag opens wide and roll silage can be easily stuffed. Therefore, roll silage can be packed easily and efficiently. Since the air suction machine is connected to the stuffing bag filled with roll silage and temporarily tightened, the air suction machine becomes difficult to come off from the stuffing bag after the start of operation. Therefore, the connection between the air suction machine and the stuffing bag will not come off during the process of removing air from the stuffing bag.
Air purge work can be carried out efficiently. Roughly speaking, the air inside the stuffing bag filled with roll silage is removed and the graft opening is tightened, creating a vacuum inside the bag and reducing its bulk. Therefore, the rolled silage packed in the stuffing bag is prevented from being quickly deteriorated by air, and is convenient for transportation, storage, etc. Also, when scooping out the mouth frame after filling the stuffing bag with rolled silage, you can easily make a mistake by folding it. Therefore, the opening of the stuffing bag can be quickly closed, and the next air suction machine connection operation can be easily completed.
