TECHNICAL FIELD
[0001] The utility model relates to a granular ammonium nitrate ton packaging bag bottom breaking device belongs to metallurgical industry manufacturing equipment technical field. BACKGROUND
[0002] Ammonium nitrate is the main raw material of civilian explosive production. At present, the ammonium nitrate used by domestic civilian explosive production enterprises is mostly granular, and the capacity of each bag is one ton. Through investigation, the current domestic civilian explosive production enterprises use ton bags of ammonium nitrate to produce raw materials, first use a forklift to pick the granular ammonium nitrate ton packaging bag to the top of the feeding port, and then manually cut the ammonium nitrate packaging bag with a knife. This method of manually cutting the ammonium nitrate packaging bag has the following problems:
[0003] (1) Since the ton packaging bag is made of PVC material and is relatively thick, it is difficult to cut a suitable opening at the bottom with a handheld knife at one time. At least two times are needed to cut a "cross" opening. Occasionally, multiple cuts must be made due to dull knives or improper knife angle control, thereby increasing labor intensity;
[0004] (2) Due to the influence of the operator's technique, the size of the cut is not uniform, which leads to unstable feeding speed. If the opening is too large, the feeding speed will be too fast, which may cause ammonium nitrate to spill. If the opening is small, the feeding speed will be slow, thereby affecting production efficiency;
[0005] (3) When manually cutting the packaging bag, the worker needs to stretch his arm to the lower part of the packaging bag due to the size limitation of the knife, cannot see the cutting state of the knife, and can only control the knife by feeling, which may cause personal injury.
[0006] In view of the above factors, a granular ammonium nitrate ton packaging bag bottom cutting device is proposed to improve the ton granular ammonium nitrate feeding efficiency, reduce the labor intensity and personal injury risk of workers, and improve the intrinsic safety level of the explosive production process. CONTENT OF THE UTILITY MODEL
[0007] The utility model aims to provide a granular ammonium nitrate ton packaging bag bottom breaking device, which can realize fast breaking and feeding of the ton packaging bag from the bottom, effectively reduce labor intensity and personal injury accident risk, improve production efficiency and the intrinsic safety level of the production process, and solve the problems in the background technology.
[0008] The technical solution of the utility model is:
[0009] A granular ammonium nitrate ton packaging bag bottom breaking device comprises three blades and three knife holders. The knife holder is long strip-shaped, the upper ends of the three knife holders are fixed together to form a tripod, one blade is fixed in the length direction of each knife holder, and the knife edges of the three blades all face the outside of the tripod.
[0010] The lower end of each knife holder in the tripod is provided with a foot.
[0011] The adjacent two knife holders in the tripod are provided with a reinforcing beam.
[0012] The angle between each knife holder in the tripod and the horizontal plane is 60-75 degrees.
[0013] The utility model discloses the beneficial effect is: the utility model discloses simple structure, convenient to use can replace manual granular ammonium nitrate ton package bag bottom breakage, the operation of feeding operation, has the advantages such as high breakage efficiency, regular incision, zero operation accident hidden danger, can realize ton package bag from the bottom fast breakage, the purpose of fast feeding, can effectively reduce the labor intensity and personal injury accident risk, improve production efficiency. BRIEF DESCRIPTION OF DRAWINGS
[0014] Figure 1 It is the schematic diagram of the utility model;
[0015] In the drawing: blade 1, knife holder 2, reinforcing beam 3, foot 4. DETAILED DESCRIPTION
[0016] The utility model will be further described by examples in connection with the drawings.
[0017] Referring to the accompanying Figure 1 A granular ammonium nitrate ton package bag bottom breakage device contains three blades 1 and three knife holders 2, the knife holder 2 is long strip shape, the upper end of three knife holders 2 is fixed together to form a tripod, the length direction of each knife holder 2 is fixed with one blade 1, and the cutting edge of three blades 1 is all towards the outside of the tripod.
[0018] In the embodiment, referring to the accompanying Figure 1 The breakage device contains three blades 1, three knife holders 2, three reinforcing beams 3 and three feet 4, wherein:
[0019] Three blades 1 and three feet 4 are all made of stainless steel plate material of appropriate thickness, three knife holders 2 and three reinforcing beams 3 are all made of stainless steel profile, and the components are combined together by welding, forming a tripod.
[0020] Three blades 1 are welded on three knife holders 2 respectively, the upper end of three knife holders 2 is welded together, the lower end of three knife holders 2 is welded with one foot 4 respectively, reinforcing beam 3 is welded between the adjacent two knife holders 2 of three knife holders 2, and the angle between each knife holder 2 and the horizontal plane is 60-75 degrees, and the whole is a stable tripod structure.
[0021] When using, first, use the forklift to lift the ton bag granular ammonium nitrate to the top of the device, and the bottom of the bag is slightly higher than the device. Then, operate the forklift to lower the ton bag. The bottom of the ton bag is cut into a "Y" shape by the three blades 1 in the device. The ammonium nitrate in the ton bag falls into the receiving port below by gravity, and the feeding operation is completed.
