Abstract

To prevent the incursion of poisonous gas in the skin plate by blocking a ring shaped gap in the incursion of the poisonous gas is detected during the excavation. When the concentration of poisonous gas in a tunnel becomes higher than a certain value in the course of forming the tunnel by excavating a bedrock, while the concentration is indicated in a concentration indicator 15, an alarm is raised from an alarm system 16. In the case the concentration becomes further higher, a starting signal is transmitted to a compressor 12 from the alarm system 16 to operate it, a tube 11 is expanded by injecting compressed air in the tube 11, and the inside thereof is brought into close contact with the outside of segments S in an adherable manner. The inside of the tunnel and inside of skin plate 2 are completely cut off by blocking a ring- shaped gap A between the skin plate 2 and segments S in an air-tight state inside the tube 11, the poisonous gas G flowed inside the tunnel is prevented from flowing in the skin plate 2.

Description

Bag for storing grains

The present invention relates to a kind of novel additional strengthening that is mainly used in the bag for storing grains upper limb peristome that is called the combine bag.

The widely used in the past bag for storing grains that constitutes by the cloth quality, it is of a size of vertical 80cm usually, and about horizontal wide 58cm, the upper limb of bag is provided with the peristome that fastener etc. can open and close, and two side corner sections of while at this peristome are sewed with reinforcement cloth, have and run through buttonhole.

In recent years, also there are as everyone knows in the middle of the upper limb of above-mentioned bag pros and cons and lower edge cooresponding to be sewed with the bag for storing grains of handle with it.

Above-mentioned well-known bag for storing grains, during with the paddy of results such as combination machine, its loaded weight is about 30kg in collection, so when its upper limb is made handle, must be sewed with the banded reinforcement cloth that is prefabricated into of interpolation at the inward flange of peristome, to strengthen the force part of handle.Yet take time and energy when so not only making, the manufacturing cost height, and only make when strengthening cloth, also can make the hard straight degree of edge of opening portion not enough, when causing the paddy that collection sent by combination machine passage wind, because influences such as its vibration and blast make peristome disengaging passage, paddy scatters and disappears outside bag, and this has become a research topic.

At above-mentioned situation, the present invention is when strengthening the edge of opening of above-mentioned bag for storing grains, do not use other cloth, just the total length severing of the bag blank that is made of cloth quality etc. is become than the lengthwise of bag main body usually to prolong 10-15cm, fold this prolongation more than 2 times to the inside or laterally along its opening, thereby constitute the upper limb folded part, make the fastener of regulation in opening edge two inboards of this folding part respectively, and make top handle etc. in each outside central authorities.

Bag for storing grains by above-mentioned formation, with make at the peristome periphery other reinforcement cloth before bag relatively, when the work of making of this position is obviously simplified, because it is folding, the overlapping cloth material of peristome periphery is reached more than three layers, thereby it is suitable straightforward firmly that this part is had, and played fastener and handle that this part is installed and made crash-resistant special result.

Bag for storing grains of the present invention, different with the additional strengthening of rim openings portion on the former bag main body, have the peristome operation of making is on every side simplified significantly, work capacity alleviates to be become possible the time, fastener and handle that this part is made can be firm fully, thereby make manufacturing cost be kept cheap remarkable result.

In addition, at above-mentioned edge of opening because the folding above cloth that haves three layers, have suitable straightforward firmly, so this bag for storing grains, particularly as the combine bag in collection during from paddy that the escape route of combination machine is discharged, even be subjected to its vibration and influence of blast, this bag main body yet can not come off and causes the accident from passage, helps very much the raising of yield rate.

Fig. 1 is the bag for storing grains front view of embodiment.Fig. 2 is the local amplification profile of the bag for storing grains upper limb folded part of embodiment.Fig. 3 is the bag for storing grains front view that changes.Fig. 4 is the bag for storing grains front view of another variation.

Explain details of the present invention below in conjunction with an embodiment shown in the drawings.1 is the bag main body of being made by the cloth quality among the figure, the 2nd, along bag upper limb folding part of the width that requires of main body upper opening edge 1 ' total length setting, the 3rd, near the inboard upper limb of above-mentioned folding part 2 by the fastener of base cloth 3 ' make, the 4th, on top run through on two side corner sections of edge folding part 2 suitable reinforced sheet 4 ' buttonhole, the 5th, on the pros and cons of bag main body 1, be positioned at the top handle that the central authorities of above-mentioned folding part 2 make respectively.

6 is lower edge folding parts of bag main body 1 among the figure, the 7th, and the bottom handle of making in the central authorities of this folding part 6 relative with top handle 5.

As shown in Figure 2, the bag main body 1 of present embodiment is by normally used storing grains bag material, be that the cloth quality constitutes, the length severing of the upper edge side of bag blank is become than bag desired lengthwise of main body to many 10cm, then this part is inwardly folded twice along the peristome periphery, each folding 5cm, along its bottom in addition sewing machine lignilite 2 ', thereby form the upper limb folding part 2 that overlaps 3 layers of cloth altogether.

Like this, after the edge of opening of bag main body 1 is strengthened, its edge of opening 1 ' two medial surfaces sew up the base cloth 3 of fastener 3 ', then in the middle of the outside of this folding part 2 with computer controlled sewing machine etc. sew up two foots 5 of handle 5 ', 5 ', and then the reinforced sheet 4 made such as the leather of two side corner sections by above-mentioned folding part 2 ' offer and run through buttonhole 4.

The folding times of the blank of above-mentioned upper limb folding part 2, be not limited to 2 times of present embodiment, thickness according to the bag blank, intensity etc., also collapsible more than 3 times, be not limited only to inwardly foldingly simultaneously, folded-outly also can, in order to keep the installation strength of fastener 3 and handle 5, folding times is wanted more than 2 times at least.The folding width of upper limb folding part 2 (up and down long) also is not limited to the 5cm of present embodiment in addition, according to two foots 5 of top handle ' sewing position can change at any time.

In the above-described embodiments, top handle 5 is the U font, makes in the folding part 2 central authorities, and is outstanding outside bag main body 1.Also can be as shown in Figure 3, the top handle 50 of " I " font its two foot 50 ', 50 ' locate to make in the folding part 20 central authorities.So, top handle 50 is just outwards outstanding from bag main body 10, so when bag for storing grains inserted the escape route of combination machine etc. as the combine bag, top handle 50 can not be in the way.

In addition, as shown in Figure 4, top handle 500 is the U font, is positioned at the central authorities of folding part 200, and is outstanding in bag main body 100, its two foot 500 ', 500 ' to make in the folding part 200 central authorities also passable.Like this, top handle 500 is outstanding outside bag main body 100, so the same with the situation of Fig. 3, top handle 500 can not be in the way, even when a bag main body 100 is filled, hand also rides on the top handle 500 easily.
