Abstract
The invention discloses a kind of massive asphalts just to unload rectangular bag body made of packaging bag, including bag body and bottom cover enclosing, and bag body is double-layer structure, including outer layer bag body and inner bag；Bag body lower position is equipped with sandwich composite construction, sandwich composite construction is made of support plate fixed in inner bag, outer layer bag body and the interlayer that is arranged between inner bag and outer layer bag body, bottom cover is equipped with the groove being made of outside raised line and inside raised line, groove corresponds to the support Board position, is detachably connected bag body and bottom cover by way of concave-convex grafting；Bottom cover is connect by hasp with bag body；Hasp includes fixed part and latch portion, and fixed part is fixed on the outside of bottom cover on raised line lateral wall, and latch portion cooperation is fixed on the sandwich composite construction periphery wall；The present invention increases detachable bottom cover, while the catch assembly by being welded on bottom cover and bag body for traditional packaging bag, realizes being detachably connected between bottom cover and bag body, and unloading efficiency is high.
Description
Technical field
The present invention relates to packaging bag technical fields, just unload packaging bag more particularly to a kind of massive asphalt.
Background technique
Staple product of the pitch as petrochemical industry, has been widely applied to the fields such as road and engineering construction, and China is every
At 25,000,000 tons or so, Zhejiang blueness has two kinds of storage forms of liquid and solid-state, solid-state and splitting dress, barreled, bulk for year bituminous production
Deng；It is wherein blocky that special requirement is packaged with to it due to the features such as shape is irregular, size is uneven, carrying is inconvenient；Iron
Barreled general cost is larger, takes up space also more, and need to often heat repeatedly when in use, and transportation cost increases, and cannot
Leakage accident is avoided, and pitch can be often adhered on asphalt barrel, causes to waste；And packaging bag generally uses bag in the prior art
The discharge port discharging of body top, is not easy to the discharging of massive asphalt, causes the decline of hauling operation efficiency.
Summary of the invention
The purpose of the present invention is to solve the above the deficiencies in the prior art, proposes a kind of massive asphalt and just unload packaging
Rectangular bag body made of bag, including bag body and bottom cover enclosing, the bag body are double-layer structure, including outer layer bag body and inner layer bag
Body；
Bag body lower position be equipped with sandwich composite construction, the sandwich composite construction by inner bag, outer layer bag body with
And support plate composition fixed in the interlayer between inner bag and outer layer bag body is set,
The bottom cover is equipped with the groove being made of outside raised line and inside raised line, and the groove corresponds to the support plate
Position is detachably connected the bag body and bottom cover by way of concave-convex grafting；Bottom cover is connect by hasp with bag body；It is described
Hasp include fixed part and latch portion, the fixed part is fixed on the outside of bottom cover on raised line lateral wall, and latch portion cooperation is solid
It is scheduled on the sandwich composite construction periphery wall；
Elastic beam mouth is sewed at the bag body sack, the elastic bundling port end portion forms feed inlet, elastic beam mouth
End is equipped with draw-string hole, is additionally provided with top drawstring in the draw-string hole.
Preferably, there are four the hasp is set, it is uniformly arranged on bag body four sides respectively.
Preferably, the bag body four corners are equipped with across angle suspender belt.
Preferably, it is provided with multi-turn stiffener at across the foot suspender belt, the stiffener is fixedly connected with bag body.
Beneficial effects of the present invention are as follows: the present invention increases detachable bottom cover, together for traditional packaging bag
When by the catch assembly that is welded on bottom cover and bag body, realize being detachably connected between bottom cover and bag body, material automatically from
Bag body lower part is drawn off, and keeps entire discharge process simple and quick, and unloading efficiency is high；Bumps between the bottom cover and bag body of bag body lower part
Inserting mode brings preferable sealing function to packaging bag, and packaging bag can be repeated as many times and utilize, energy conservation and environmental protection.
