[Industrial applications]

 The present invention relates to a mechanism for discharging contents in a large-sized grain storage bag. More specifically, in recent years, the grain storage bag tends to be large in size in order to improve the efficiency and labor saving of harvesting in agricultural work. Since these large-sized grain storage bags were to be dried immediately after harvesting, the storage bag was lifted and the bottom opening was opened and it was moved to the pit of the dryer. Many small and medium-sized farmers who do not have pits or hoisting equipment have found it difficult to use large grain storage bags, but this is an attempt to improve all at once.

[0002]

[Prior art]

 The grain storage bag according to the present invention is intended for many grains such as rice and wheat, but for simplicity of description below, the storage target will be limited to raw rice. The conventional storage bag for raw rice, etc. faces the opening of the raw rice discharge duct attached to the combine, and a relatively small storage bag for raw rice (hereinafter referred to as “small combine bag”) made of net is used as a combine. It is detachably attached via a hanging rod provided, and when it is full, the opening of the bag is closed and it is thrown down one by one on the field, and the bag on the field is later collected and transported to the drying facility. there were.

On the other hand, in recent years, with the development of a combine tank containing a large-capacity (0.7 to 1 ton) Glen tank, the combine bag has also become large in size of 1 ton class, and it is It has contributed to a significant speedup and labor saving of harvesting and drying operations.

[0006] Thus, in such a large combine bag, one or a plurality of empty bags are usually mounted on the bed of a truck so as to be self-supporting, and the raw rice stored in the grain tank of the combine is sequentially combined. The procedure was to transfer it to a rice center or a home drier, but in order to empty it in a drying facility, a full combine bag should be kept separately by a hoist or hawk lift. It was essential that the work was to be lifted up to the height of the floor and then to open the bottom opening.

[0005]

[Problems to be solved by the device]

 Generally, unhulled rice before threshing (same for other cereals) has an angle of repose that causes natural flow of 40 to 50 °, and in order to naturally discharge the unhulled rice in the bag of convenin using gravity. It is a requirement that the Conban-in bag be lifted up and discharged from the bottom opening, or that the bag be installed beforehand at a fairly high position on the truck bed. However, the former requires a lifting facility above the pit at the same time as the pit is recessed below the ground level, and the latter requires the height of the bag to be installed on the loading platform because of the combine rice unloading cylinder. Due to restrictions, natural emissions were not possible.

As described above, in the large combine bag, since the bag filled with raw paddy had to be hoisted by using a hoist or other appropriate means, it was dried like a rice center or a full-time farmer. There is no problem in a place where there is a pit leading to the machine and a lifting facility, but for small and medium-sized farms such as part-time farmers, there is no room in the resources and space to have such equipment, and to the dryer. Since the loading position is above the level, it is difficult to use a large combine bag, and it is necessary to rely on a small old combine combine bag, which is highly efficient and labor-saving. The problem was that they could not utilize the Nine-bag.

[0007]

[Means for Solving the Problems]

 In view of such circumstances, as a result of diligent research and improvement, the present inventor can efficiently transfer the contents without lifting the bag for discharging the raw rice stored in the large combine bag. The purpose is to develop a device, and especially for small and medium-sized farmers to use large combine bags to improve efficiency and save labor.

That is, in order to achieve the above-mentioned object, the present invention provides an opening into which a small and high-speed belt conveyor can be inserted in advance on the bottom circumference of a large combine bag, and a tubular cloth of a certain length is provided in the opening. It was extended and mounted so that the tip side of the conveyor (the transfer direction = the same applies hereinafter) was mounted so as to be exposed outside the bag for a predetermined length.

Further, a means of laying spacers whose upper surface is inclined toward the upper edges of both side plates of the conveyor is also used on both sides of the conveyor at the bottom of the bag.

[0010]

[Action]

 The device of the present invention configured as described above is mounted on an empty bag in advance, and the front end of the conveyor exposed from the circumference of the bottom of the bag is mounted so that it slightly projects from the trailing edge of the truck bed, and then the combine delivery container is installed at the site. Transfer the raw rice through the bag into the bag, carry it into the home dryer, and back the track so that the protruding end of the conveyor faces the inlet of the dryer, and then drive the conveyor. With the movement of the paddy moving on the conveyor at high speed, the upper paddy moves on the conveyor in sequence, and almost all the raw paddy in the combine bag can be discharged quickly.

Further, in the case where a spacer such as an air bag is laid, as the paddy moves on the conveyor at a high speed, the paddy on the upper side directly or along the slope of the paddy falls on the conveyer one by one, and then the combine is carried out. It has a special effect that the whole amount of raw rice in the bag is discharged quickly.

【Example】

 Hereinafter, the structure of the present invention will be described in more detail with reference to the embodiments shown in the drawings. In the drawings, 1 is a truck bed, 2 is a large combine bag having a height of 1300 mm and a diameter of 1200 mm, which is mounted on the bed, and 3 are It is a tubular cloth extended into a through hole 3'opened at one place around the waist close to the bottom of the bag, and the through hole 3'and the tubular cloth 3 are both side plates 4'of a small conveyor 4. The shape is such that it can be inserted in close contact.

Reference numeral 5 denotes an inner bottom surface of the combine bag 2, which is a semi-circular (accurately speaking) plane-shaped air bag whose upper surface when inflated is inclined toward the upper edges of both side plates 4'of the conveyor. The spacer 5 according to the present invention is not limited to the above-mentioned air bag, but may be made of any material and structure as long as it is, for example, a foamed polystyrene molded body that can effectively guide raw paddy on a conveyor. It's not a question.

In the figure, 6 is an upper opening of the combine bag 2, 7 is a combine carrying-out tube in which the discharge port 7 ′ is movable facing the upper opening of the combine bag, and the combine bag 2 shown is a self-supporting type. An example is shown in the figure, 9a is a supporting ring that is provided in a row in several places around the bag body, and 9b is a column made of glass fiber, etc., so that the bag main body can be opened without using other holders. It can be self-sustaining.

Next, a description will be given of how to use the large combine bag of the present invention having the above-described structure. An empty bag of the large combine bag 2 is mounted on the rear part of the loading platform 1 of the truck in a self-supporting manner. From the tubular cloth 3 provided around the circumference, the belt conveyor 4 is inserted with the front end side facing toward the back to a position reaching the inner surface of the bag, and about 30 to 50 cm on the front end side is exposed to the outside of the bag.

On the other hand, the two inflated airbags 5 and 5 are laid so that the upper surfaces thereof are inclined downward toward both side plates of the belt conveyor 4, and the exposed tip end side of the conveyor. Is set so that it projects about 30 cm from the rear edge of the loading platform 1.

Then, the truck is moved to the harvesting site to wait until the combine grain tank is full.

On the other hand, when the combine tank in which the Glen tank is full comes to the truck position, the discharge port 7 ′ of the carrying-out cylinder 7 is exposed to the upper opening 6 of the combine bag, and the raw rice 8 in the Glen tank is removed. In this case, when the combine bag is filled with raw rice, in this case, the truck is operated as it is to return to the private drying area, and the tip side of the conveyor 4 protruding from the trailing edge of the cargo bed is placed in the dryer. By arranging it on the input port and driving the conveyor, the entire amount of paddy in the bag is quickly discharged.

The conveyor 4 in the present invention is not limited to a belt conveyor, and a chain conveyor, a screw conveyor, or the like may be freely selected, but a high speed drive is preferable.
