DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] Reference Figure 1-Figure 4 , a construction waste crushing equipment, including a box body 1, a fixed jaw plate 2 is welded on the inner wall of one side of the box body 1, and a movable jaw plate 3 is rotatably connected to the top of the box body 1, and the movable jaw plate 3 is arranged opposite to the fixed jaw plate 2. A hydraulic cylinder 5 is fixed to the inner wall of one side of the box body 1 by bolts, and one end of the piston rod of the hydraulic cylinder 5 is rotatably connected to a connecting rod 4, and the other end of the connecting rod 4 is rotatably connected to the movable jaw plate 3. Driven by the hydraulic cylinder 5, the connecting rod 4 rotates, thereby driving the movable jaw plate 3 to rotate, and then the construction waste is squeezed and crushed by the coordinated use of the movable jaw plate 3 and the fixed jaw plate 2, so as to perform preliminary crushing of the construction waste. Two crushing rollers 6 are rotatably inserted between the inner walls on both sides of the box body 1, and a first motor 7 is fixed to the inner wall of the bottom of the box body 1 by bolts. The output end of the first motor 7 is keyed to a main shaft 8, and a plurality of blades 9 are fixed to the top of the main shaft 8 by bolts. Driven by the first motor 7, the main shaft 8 rotates, thereby driving the blades 9 to rotate, and then the construction waste is crushed three times. A discharge port 10 is provided at the bottom of one side of the box body 1.

[0025] One end of the crushing roller 6 is key-connected with a gear 11, and the two gears 11 are meshed with each other. A fixing bracket 12 is fixed to the outer wall of one side of the box body 1 by bolts, and a second motor 13 is fixed to the top of the fixing bracket 12 by bolts. The output end of the second motor 13 is fixedly connected to one end of one of the crushing rollers 6. The crushing roller 6 is driven to rotate by the second motor 13 and the meshing of the two gears 11, thereby performing secondary crushing of the construction waste. The bottom of the box body 1 is fixed with a base 14 by bolts, and the base 14 is fixed to the bottom of the box body 1 by bolts. Two baffles 15 are welded on the top, and a storage box 16 is slidably inserted on one side of the base 14. Construction waste falls into the storage box 16 for collection. The storage box 16 is located below the discharge port 10. A handle is fixed to the outer wall of one side of the storage box 16 by bolts. One side of the fixed jaw plate 2 and one side of the movable jaw plate 3 are integrally formed with multiple protrusions 17. The protrusions 17 on the fixed jaw plate 2 and the movable jaw plate 3 can better crush the construction waste. Inclined plates 18 are welded to the inner walls of both sides of the box body 1, and the blade 9 is located between the two inclined plates 18.

[0026] The working principle of this embodiment is as follows: when in use, construction waste is put into the box body 1. In the box body 1, first, the connecting rod 4 is rotated under the drive of the hydraulic cylinder 5, thereby driving the movable jaw plate 3 to rotate, and then the construction waste is squeezed and crushed through the coordinated use of the movable jaw plate 3 and the fixed jaw plate 2, so that the construction waste is initially crushed, and then the initially crushed construction waste falls on the crushing roller 6, and then driven by the second motor 13 and the meshing of the two gears 11, the crushing roller 6 is driven to rotate, so that the construction waste is secondarily crushed, and the construction waste after the second crushing falls on the blade 9, and then, driven by the first motor 7, the main shaft 8 is rotated, thereby driving the blade 9 to rotate, and then the construction waste is crushed for the third time, and then the construction waste after the third crushing is discharged from the box body 1 from the discharge port 10, and then the construction waste falls into the storage box 16 for collection.
