The utility model solves the problem of low bag-breaking efficiency of the bag-breaking device in the prior art.

[0004] However, the above patent still has certain disadvantages when in use: the existing bag-breaking device is large in volume, heavy in weight, high in cost, and not convenient for personnel to carry. Moreover, the disassembly and assembly of the tool are also rather troublesome, which is not convenient for subsequent cleaning, maintenance or replacement of the tool. Finally, due to the fixed position of the tool and mostly exposed to the outside, there are certain safety hazards when the device is not in use.

[0005] For the problems in the related art, no effective solution has been proposed yet. Content of the Utility Model

[0026] To further illustrate the embodiments, the present invention provides accompanying drawings, which are part of the disclosure of the present invention. They are mainly used to illustrate the embodiments and can cooperate with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those of ordinary skill in the art should be able to understand other possible implementation manners and the advantages of the present invention. The components in the drawings are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0027] According to an embodiment of the present invention, a bag-breaking device for chemical fertilizer raw materials is provided.

[0028] Now, the present invention will be further described in combination with the accompanying drawings and specific implementation manners. As Figures 1-3 shown, a bag-breaking device for chemical fertilizer raw materials according to an embodiment of the present invention includes a storage rod 1. Second sliding grooves 14 and third sliding grooves 15 are respectively formed on both sides inside the storage rod 1. A connecting seat 6 and a lifting rod 10 are respectively slidably connected in the second sliding groove 14 and the third sliding groove 15. A first sliding groove 13 is formed inside the connecting seat 6. A cutting blade 7 is slidably connected in the first sliding groove 13. A pyramidal puncturing head 9 is fixedly connected to the top of the lifting rod 10. The cutting blade 7 is used to cut the flat packaging bag, and the pyramidal puncturing head 9 is used to puncture the bottom of the packaging bag lifted to a high place by tools such as manual labor or a crane.

[0029] In one embodiment, an insertion hole 11 is formed at the top end position on the surface of the cutting blade 7.

[0030] In one embodiment, when the cutting blade 7 is completely inserted into the first sliding groove 13, it is fixed to the connecting seat 6 through a fastening bolt 8. A threaded hole 12 for connecting the fastening bolt 8 is formed at the top end position on one side surface inside the connecting seat 6. The fastening bolt 8 is passed through the insertion hole 11 formed at the top end of the cutting blade 7 and then screwed into the threaded hole 12 to fix the cutting blade 7 on the connecting seat 6. And when the fastening bolt 8 is tightened, the nut of the fastening bolt 8 is located in the circular hole formed at the top end position on one side surface of the connecting seat 6, so as to prevent the nut from protruding when the connecting seat 6 moves in the second sliding groove 14, resulting in the connecting seat 6 not being able to be completely received in the second sliding groove 14.

[0031] In one embodiment, through grooves 3 are formed on the front end face and the right side surface of the storage rod 1, and a plurality of fixing holes 2 are equidistantly formed on the surface of the storage rod 1 on one side of the through groove 3.

[0032] In one embodiment, moving rods 5 are fixedly connected to the bottom end position of one side surface of the connecting seat 6 and the bottom end position of one side surface of the lifting rod 10. One end of each moving rod 5 passes through the corresponding through groove 3 and is fixedly installed with a positioning component 4. By pushing the moving rod 5, the connecting seat 6 or the lifting rod 10 is driven to move, so as to adjust the unfolding length of the cutting blade 7 and the height of the pyramidal puncturing head 9, and then the adjusted connecting seat 6 or lifting rod 10 is fixed by the positioning component 4.

[0033] In one embodiment, the positioning component 4 is composed of a positioning frame 16 and a movable piece 18. The movable piece 18 is rotatably connected to the inside of the positioning frame 16. One end of the bottom surface of the movable piece 18 is fixedly connected with a positioning rod 19, and the other end of the bottom surface of the movable piece 18 is fixedly connected with a spring 17. By pressing one end of the movable piece 18, the spring 17 connected to one end of the bottom surface of the movable piece 18 is contracted downward, thereby driving the positioning rod 19 at the other end of the bottom surface of the movable piece 18 to lift upward. After that, when the connecting seat 6 or the lifting rod 10 moves to a suitable height, the movable piece 18 is released, and the positioning rod 19 is driven to reset downward under the elasticity of the spring 17, so as to insert it into the corresponding fixing hole 2 to fix the connecting seat 6 or the lifting rod 10.

[0034] Working principle: During actual use, when it is necessary to break the bag of the flat packaging bag, press one end of the movable piece 18, so that the spring 17 connected to one end of the bottom surface of the movable piece 18 contracts downward, thereby driving the positioning rod 19 at the other end of the bottom surface of the movable piece 18 to lift upward. After that, push the moving rod 5 to drive the connecting seat 6 to move upward and unfold. When the cutting blade 7 connected in the connecting seat 6 exposes a suitable length, release the movable piece 18, and the positioning rod 19 is driven to reset downward under the elasticity of the spring 17, so as to insert it into the corresponding fixing hole 2 to fix the cutting blade 7, and then quickly cut the packaging bag through the blade. When the raw material packaging bag is lifted to a high place by tools such as manual labor or a crane, then move the lifting rod 10 upward to drive the pyramidal puncturing head 9 to move out of the third sliding groove 15, and then aim the pyramidal puncturing head 9 at the bottom of the packaging bag and pierce it for bag breaking operation. Finally, when the bag breaking is over, the connecting seat 6 or the lifting rod 10 is stored in the second sliding groove 14 and the third sliding groove 15, which not only reduces the space occupation but also avoids the blade or the puncturing head being exposed to the outside and bringing potential safety hazards to personnel; the cutting blade 7 can be quickly disassembled and assembled through the first sliding groove 13, and the cutting blade 7 can be fixed on the connecting seat 6 through the fastening bolt 8 and the threaded hole 12, which is convenient for subsequent personnel to clean, maintain or replace the blade. The whole device has the advantages of small volume, easy to carry, reducing potential safety hazards, and convenient disassembly and assembly of the blade.
