Abstract

PURPOSE:To provide a bag for grain with durability by a constitution wherein a handle is provided at an opening on the top of the bag, at which a fastener is fitted. CONSTITUTION:A bag 3 which has an opening 2 on the top is constituted of a flexible material 1 such as synthetic resin material, fabric and others, and an input/discharge port 6 for grain is formed by fitting a fastener 5 which can be opened or closed by an opening/closing tool 4, at the opening 2 of the bag 3, and a handle 7 is attached at least on one side of the front and rear both surfaces of the input/discharge port 6 so that the bag can be held by being hung, for the constitution. The title bag for grain is constituted in such a manner that at both ends or one end of the fastener 5, the front and rear both surfaces of the bag material are unseparatably joined.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a grain bag such as a combine harvester and can be used not only in combine harvesters but also in harvesters.

2. Description of the Related Art As shown in, for example, Japanese Utility Model Publication No. 1-10359, a conventional grain bag of the above type is suspended for insertion into a bag supporting rod having a narrow space between the front and back sides of an upper charging / discharging port. Some have a string. This grain bag is convenient to handle because it can be carried by holding the hanging string, but if you hold only one of the upper strings and lift it with the grain filled, it will be damaged and the fastener section will be damaged. It is often a problem.

[0004] That is, this seed grain bag is to carry about 30 kg of grain, and as described above, the lower handle and the hanging string on only one side of the upper part are grasped and held horizontally. If you lift it while holding it, the weight of the grain will be fastened.
There were many cases where the opening and closing device was concentrated and damaged from that part.

[0005]

The grain bag has a handle on the lower part and an upper part for easy carrying, but the input / discharge port on the upper part has a handle on both front and back sides, or only on one side. I put a handle on. In such a configuration, the grain bag, when the lower handle and the handle on one side of the upper part are grasped and lifted with the grain filled,
Occasionally, the fastener parts of the fastener were heavily loaded and damaged.

In particular, in a grain bag used for a long period of time, the fasteners and the opening / closing tools were often fatigued and damaged.

[0007]

The present invention takes the following technical means in order to achieve the above object.
That is, a synthetic resin material, cloth, or other flexible material 1 constitutes a bag 3 having an opening 2 at an upper portion thereof, and the opening 2 of the bag 3 is a fastener 5 which can be freely opened and closed by an opening / closing tool 4.
Is formed to form a grain charging / discharging port 6, and a handle 7 is attached to at least one side of both the front and back sides of the charging / discharging port 6 so as to be capable of being suspended, and both ends of the fastener 5 Alternatively, the grain bag is formed by joining the front and back both sides of the bag inseparably at one end.

[0008]

EXAMPLE First, the structure will be described. Grain bag 3
Is made by cutting a material 1 such as a cylindrical synthetic resin material to an appropriate size, folding the lower part and sewing it together to form a bottom part, and a fastener 5 which can be freely opened and closed by an opening / closing tool 4 in the upper opening part 2. An attachment and discharge port 6 for the grain is configured.

The material 1 is not limited to the above synthetic resin material, and may be a soft material such as cloth.
The handles 7 and 7'can be sewn on the upper and lower surfaces of the grain bag 3 on both sides of the grain input / discharge port 6 and lifted up. The handle 7 is
It may be configured to be attached to only one of the front and back sides.

The grain bag 3 has a structure in which the front and back surfaces are sewn together at one end portion of the fastener 5 so that they cannot be separated, and a safety zone a for the opening / closing tool 4 is formed. The safety zone a may be provided on both sides of the fastener-5. Reference numeral 8 indicates a lower handle. An eyelet 9 is configured to be inserted through and supported by a bag support rod 10 of the combine.

The combine is as shown in FIG.
A threshing machine 13 is mounted on a chassis 12 having a crawler 11, and a cutting and conveying device 14 is provided in the front part.
Next, the operation will be described. In carrying out the combine work, first, the grain bag 3 is attached by inserting the eyelets 9 into the bag support rod 10 and attaching a plurality of sheets at the same time, and the opening 2 of the foremost one is located below the grain discharge port. Peek into.

When the combine work is started, the grain culms in the field are mowed along with the forward movement of the chassis 12 and supplied to the threshing machine 13 by the mowing and conveying device 14 to be threshed. Next, the grain is conveyed from the thresher 13 to the grain tank and is sequentially filled into the grain bag 3 from the outlet. The bag 3 filled with grains in this way is pulled out to the front with the work of loading the next empty bag, and the fastener 5 is closed by operating the opening / closing tool 4 to pull it out from the bag support rod 10 and put it in a field scene. Be lowered.

Next, when the worker carries the grain bag 3 from the field to the truck waiting on the farm road, the grain bag 3 is carried by grasping one side of the upper handles 7 and 7'and the lower handle 8. Since the opening / closing tool 4 of the fastener 5 is located in the safety zone a where the front and back of the bag 3 are sewn together,
The weight of the grain is hardly applied to the part of the opening / closing tool 4 of the fastener 5 in the direction of tearing up and down, and the damage can be prevented in advance.

Next, even when the grain bag 3 is collected, brought back to the barn of the farmer, and transferred to the hopper of the dryer, the opening / closing tool 4 is used.
When the fastener 5 is opened by pulling from one side to the other side, the opening / closing tool 4 is within the range of the safety zone a. The grain bag 3 is held by the lower handle 8 and the handle 7 on one side of the upper portion and lifted up, and the weight of the grain is held at the joint portion where the front and back are sewn together, and the opening / closing tool 4
Therefore, the fastener 5 can be prevented from being damaged in advance.

[0015]

As described above, according to the present invention, a bag having an opening in the upper portion is formed of a synthetic resin material, cloth, or other flexible material, and the opening of the bag is opened and closed by an opening / closing tool. A free fastener is attached to form a grain charging / discharging port, and a handle can be attached to at least one side of the charging / discharging port on either side of the charging / discharging port so that both ends can be suspended. Or, at one end, it is constructed by joining the front and back both sides of the bag inseparably, so that the grain bag filled with grain is lifted for carrying or discharging the grain and vice versa. In doing so, since the opening / closing tool is located in the safety zone, even if the handle on one side of the upper opening is lifted, the force acting to tear up and down does not act on the opening / closing tool part.

Therefore, the fastener is hardly damaged, and has the effect of providing a durable value.
