[0019] Intelligent bulk material sorting module includes liftable support 7, lifting slide 3, lifting slide 3 is installed at the top of liftable support 7.Lifting slide 3 is slidably connected with bulk hopper 2 in the inside, and the bottom of lifting slide 3 is transversely penetrated with conveying belt 6, and the top of lifting slide 3 is equipped with receiving hopper 1.The liftable support of intelligent bulk material sorting device and track, can be walked on the garbage 25 ° below the heap, and the height of conveying belt is adjusted according to needs.Stale garbage is excavated by on-site excavation equipment and is put into receiving hopper 1, garbage falls into bulk hopper 2, bulk hopper 2 moves up and down on liftable slide, and then garbage in bulk hopper 2 is impacted and scattered, to facilitate subsequent intelligent sorting and fine sorting.Electric valve is arranged at the bottom of bulk hopper 2, after bulk hopper completes the scattering of stale garbage, by opening the electric valve at the bottom, stale garbage is put on the conveying belt 6 below.

[0020] The shell of the lifting slide 3 is internally provided with a pull rope cavity 15, and the inner wall of the shell of the lifting slide 3 is vertically provided with a sliding groove 18, both ends of the bulk hopper 2 penetrate through the sliding groove 18 and extend into the pull rope cavity 15, and both ends of the bulk hopper 2 are in sliding connection with the sliding groove 18. Both sides of the outside of the lifting slide 3 are provided with a motor 12, and the output shaft of the motor 12 is provided with a winding wheel 13, and the winding wheel 13 is wound with a pull rope 17, and the other end of the pull rope 17 extends into the pull rope cavity 15 and is fixedly connected with the end of the bulk hopper 2. The outside of the lifting slide 3 is provided with a first guide pulley 14, and the inside of the pull rope cavity 15 is provided with a second guide pulley 16, and the pull rope 17 passes through the first guide pulley 14 and the second guide pulley 16. The two motors 12 run synchronously and at the same speed, and when the two motors 12 rotate, the winding wheel 13 rotates to pull the pull rope 17 upward, and when it reversely rotates, the gravity of the bulk hopper 2 itself pulls the pull rope 17 downward. The motor 12 frequently reverses, so that the bulk hopper 2 is lifted and shaken to scatter the garbage in the hopper. The lifting frequency and rate are adjusted according to the identification accuracy of the stale garbage by subsequent artificial intelligence. The transmission belt 6 is made of rubber material, which is 500-800mm wide and 8-12mm thick. The bottom of the transmission belt is provided with a weight sensor, and the sensor transmits signals to the artificial intelligence control end.

[0021] The fine screening module includes a variable frequency bouncing screen 9 and a variable frequency flip-flow screen 10, the variable frequency bouncing screen 9 is located on the upper side of the variable frequency flip-flow screen 10, and the conveying end of the transmission belt 6 is located on the upper middle of the variable frequency bouncing screen 9.

The variable frequency bouncing screen 9 and the variable frequency flip-flow screen 10 are both inclined. The bottom of the variable frequency flip-flow screen 10 is provided with a conveyor belt. The resolution of the camera is 1080P, and the shape, color, size, texture and other information are transmitted to the artificial intelligence control end through the sensor. The intelligent gripper is 500-700mm wide and can grasp large pieces of garbage and long strip fabrics. The artificial intelligence algorithm analyzes the shape, color, size, texture and weight information of the garbage, converts the analysis result into a grasping instruction, and thus controls the intelligent gripper. The scattered stale garbage is conveyed on the transmission belt 6 to the rear, the high-definition camera 4 shoots the stale garbage in real time to obtain shape, color, size, texture and other information; the weight sensor on the transmission belt 6 obtains weight information, and then the artificial intelligence algorithm quickly identifies and classifies the stale garbage. The artificial intelligence algorithm converts the analysis result into an instruction to control the intelligent gripper 5 to grasp the identified large pieces of garbage, long strip fabrics and the like and send them to the external other corresponding receiving hopper. The stale garbage such as large pieces of garbage and long strip fabrics is sent to the fine screening device through the transmission belt 6.

The bounce screen frequency can be adjusted according to the particle size and processing requirements of the composted garbage. The bounce screen moves up and down through the eccentric shaft driving the screen plate. Due to the different densities and shapes of the composted garbage, the light material has a poor rebound effect and is separated out through the upper end; the large block material has a good bounce effect and is transported to the receiving hopper through the lower end of the bounce screen; and the small block material falls into the variable frequency flip-flow screen through the screen mesh.

The movement frequency of the flip-flow screen can be adjusted according to the particle size of the small block material.

[0023] The variable frequency bounce screen 9 realizes the separation of light material, large block material and small block material through fine screening equipment. The upper end and the lower end of the variable frequency bounce screen 9 are provided with corresponding receiving hoppers. The light material is transported from the upper end of the bounce screen to the light material receiving hopper, and the large block material is transported from the lower end of the bounce screen to the corresponding receiving hopper. The small block material enters the variable frequency flip-flow screen 10 through the screen mesh. The small block material is separated into small particle material, fine light material and humus through the variable frequency flip-flow screen 10. The variable frequency flip-flow screen 10 is provided with an air blower 11. The fine light material such as fine plastic sheet on the screen is transported out from the upper end of the variable frequency flip-flow screen to the corresponding receiving hopper under the action of the air blower 11. The small particle material is transported to the corresponding receiving hopper through the lower end, and the humus enters the conveying belt at the bottom and is transported to the rear station through the screen mesh of the flip-flow screen.
