Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0027] Please refer to Figures 1-5 , the construction decoration waste bag-breaking machine provides two technical solutions:

The bag-breaking mechanism includes: a driving motor 5, a plurality of cutting knives 7;

[0029] A detachable drive shaft 6, the detachable drive shaft 6 includes a main shaft 61 and a sub-shaft 62. A plurality of cutting knives 7 are all installed on the main shaft 61 through an installation component 8. A spline shaft 63 is fixedly connected to the left end of the main shaft 61. A spline shaft sleeve 64 is sleeved on the surface of the sub-shaft 62. A return spring 65 is fixedly connected between the spline shaft sleeve 64 and the sub-shaft 62. The main shaft 61 is rotatably connected to the left side of the right slider 92. The driving motor 5 is fixedly connected to the right side of the right slider 92, and the output end of the driving motor 5 is fixedly connected to the main shaft 61. The sub-shaft 62 is rotatably connected to the right side of the left slider 92;

[0030] The installation component 8, the installation component 8 includes two circular pressing blocks 81 on the left and right. Locking bolts 82 are threadedly connected to the surfaces of the two circular pressing blocks 81, and the locking bolts 82 penetrate through the circular pressing blocks 81. The two circular pressing blocks 81 clamp the left and right sides of the cutting knife 7, and gaskets 84 are arranged between the opposite sides of the two circular pressing blocks 81 and the cutting knife 7. Four ball head rods 83 are fixedly connected to the right side of the inner wall of the right circular pressing block 81 at equal intervals in the circumferential direction. A buckle component 85 for cooperating with the gasket 84 is arranged inside the left circular pressing block 81;

[0031] The buckle component 85 includes a U-shaped seat 851. The U-shaped seat 851 is fixedly connected to the left side of the inner wall of the left circular pressing block 81. An intermediate rod 852 is fixedly connected between the front and back of the inner wall of the U-shaped seat 851. Two upper and lower arc-shaped plates 853 are rotatably connected to the surface of the intermediate rod 852. A torsion spring 854 is sleeved on the surface of the intermediate rod 852. The two ends of the torsion spring 854 are respectively fixedly connected to the outer sides of the two upper and lower arc-shaped plates 853.

[0032] After the cutting knife 7 is damaged, with the cooperation of the detachable drive shaft 61 and the installation component 8, the cutting knife 7 can be quickly removed and replaced, avoiding affecting subsequent bag breaking and improving the practicability of the device during use.

[0033] The second embodiment mainly differs from the first embodiment in that: the adjustment component 9 is used to adjust the height of multiple cutting knives 7, and the adjustment component 9 includes two left and right slide grooves 91 opened on the double-rod support frame 3, and the inner surfaces of the two slide grooves 91 are slidably connected with sliders 92, and the bottoms of the inner walls of the two slide grooves 91 are rotatably connected with screw rods 93, and the screw rods 93 penetrate the double-rod support frame 3 and extend to the top of the double-rod support frame 3. The top end of the right screw rod 93 is fixedly connected with a handle 95, and the left and right sliders 92 are respectively threadedly connected to the surfaces of the two screw rods 93, and the surfaces of the two screw rods 93 located above the double-rod support frame 3 are fixedly connected with pulleys 94, and the two pulleys 94 are connected by belt transmission.

[0034] The height of the cutting blade 7 can be adjusted by adjusting the component 9, so that it can be suitable for breaking bags of construction waste of different sizes, which improves the convenience of using the device.

[0035] When in use, the construction waste is placed on the material plate 10, the driving component 4 is started to move the construction waste bag, and the driving motor 5 is started to rotate the main shaft 61, thereby driving the cutting knife 7 to rotate, so as to break the bag of construction waste. When the thickness of the construction waste is large, the screw rod 93 can be rotated by turning the handle 95, and the screw rod 93 rotates and drives the pulley 94 to rotate, and the two screw rods 93 are rotated at the same time under the transmission of the belt, thereby adjusting the height of the cutting knife 7. When the cutting knife 7 is damaged and needs to be replaced, the two locking bolts 82 are loosened, and the cutting knife 7 and the mounting component 8 are moved to the left. When it is close to the spline sleeve 64, the spline sleeve 64 is moved so that the spline sleeve 64 is separated from the spline shaft 63. At this time, a gap is formed, and the cutting knife 7 and the mounting component 8 can be removed from the main shaft. When the cutting knife 7 is installed, the two round pressing blocks 81 are aligned, so that the ball head rod 83 passes through the cutting knife 7, and the ball head rod 83 is aligned with the buckle assembly 85, so that the head of the ball head rod 83 enters between the two arc plates 853. When the head of the ball head rod 83 enters, the two arc plates 853 move away from each other, and after the arc plates 853 completely enter the inside of the two arc plates 853, the two arc plates 853 are stuck on the head of the ball head rod 83 under the action of the torsion spring 854, and then the cutting knife 7 and the installation assembly 8 are integrally mounted on the main shaft 61, and finally the locking bolt 82 is rotated to make the locking bolt 82 and the surface of the main shaft 61 tightly.
