[0026] The crane 1 drives the bagged solid particulate hazardous waste to move and transport it to the feeding mechanism 2. The packaging bag enters the opening 30, and the crane 1 contacts the moving block 39 to push the moving block 39. The moving block 39 can be retracted into the sliding groove 38, thereby driving the transmission bevel gear 2 34 to move. The transmission bevel gear 2 34 drives the transmission rod 1 35 to move, so that the transmission bevel gear 3 36 reaches a position where it can mesh with the transmission bevel gear 4 37. The lifting mechanism 2 55 drives the lifting plate 56 to rise, to drive the transmission rod 2 43 to move upward, so that the transmission bevel gear 4 37 rises and meshes with the transmission bevel gear 3 36. At this time, the driving motor 2 57 drives the driving bevel gear 62 to rotate, and the driving bevel gear 62 drives the transmission rod 2 43 to rotate through the transmission bevel gear 8 60 and the transmission bevel gear 7 54. The transmission rod 2 43 drives the transmission bevel gear 3 36 to rotate through the transmission bevel gear 4 37 and the transmission bevel gear 3 36, and the transmission bevel gear 3 36 drives the driving rod 1 33 to rotate through the linkage bar 1 42, and then drives the screw rod 2 31 to rotate through the transmission bevel gear 2 34 and the transmission bevel gear 1 32. When the screw rod 2 31 rotates, it drives the screw slider 2 29 to move, so that the two clamping blocks 27 are relatively close to each other to clamp the packaging bag. The support block 28 below the clamping block 27 can support the packaging bag, making the fixing of the packaging bag more stable. There is a gap between the two support blocks 28, which can allow the cutter 52 to pass through, and will not affect the cutting of the bottom of the packaging bag by the cutter 52.

[0027] The cutting edge of the cutter 52 faces away from the packaging bag. When the cutter 52 moves, the opening of the packaging bag is located at the rear side of the moving direction of the cutter 52, so that the solid particles of hazardous waste falling from the opening of the packaging bag will not collide with the cutter 52 and bounce up, and the cutter 52 will not affect the discharge of the solid particles of hazardous waste.

[0028] The lifting plate 56 drives the transmission rod 2 43 to descend, so that the transmission bevel gear 5 44 is meshed with the transmission bevel gear 6 45. The transmission rod 2 43 rotates to drive the transmission bevel gear 4 37 to rotate, thereby driving the moving seat 49 to move through the screw slider 3 48. The moving seat 49 drives the cutter 52 to move below the packaging bag. The lifting mechanism 1 51 drives the cutter 52 to rise, so that the cutter 52 contacts the bottom of the packaging bag. With the reversal of the transmission rod 2 43, the screw 3 47 is driven to rotate in the opposite direction, so that the moving seat 49 moves back. The cutter 52 can cut off the bottom of the packaging bag, so that the solid particles of hazardous waste inside fall down.

[0029] After the moving seat 49 returns to its original position, the lifting mechanism 2 55 drives the lifting plate 56 to rise, and adjusts the height of the transmission rod 2 43, until the transmission bevel gear 4 37 is not meshed with the transmission bevel gear 3 36, and the transmission bevel gear 5 44 is not meshed with the transmission bevel gear 6 45. And part of the linkage bar 2 53 is inserted into the screw 1 24. At this time, when the driving bevel gear 62 drives the transmission rod 2 43 to rotate, the screw 1 24 can be driven to rotate through the linkage bar 2 53, and then the height of the receiving hopper 19 can be adjusted through the screw slider 1 21. The receiving hopper 19 can be close to the packaging bag, and can better receive the solid particle hazardous waste in the packaging bag to prevent the solid particle hazardous waste from scattering. The receiving hopper 19 and the moving seat 49 are driven to move separately so that the two will not interfere with each other.

[0030] The clamping mechanism 26, the bag breaking mechanism and the lifting and lowering of the receiving hopper 19 can be driven by the driving motor 2 57, thereby reducing the number of power sources and effectively reducing costs.

[0031] Furthermore, two rollers 15 are rotatably arranged in the lower hopper 13. The rollers 15 are coaxially connected with a driving gear 18. The driving gear 18 is located outside the lower hopper 13. The two driving gears 18 are meshed with each other. A support frame 16 is arranged on the outer periphery of the lower hopper 13. A driving motor 17 is mounted on the support frame 16. The driving motor 17 drives one of the rollers 15. Through the meshing driving gears 18, when the driving motor 17 drives one of the rollers 15 to rotate, the other roller 15 rotates in the opposite direction. The solid particulate hazardous waste that falls into the lower hopper 13 is squeezed by the two rollers 15, and the solid particulate hazardous waste with a larger diameter can be broken into solid particulate hazardous waste with a smaller diameter. Distributors 14 are arranged above and below the rollers 15 in the lower hopper 13.

[0032] A vibrator 9 is provided outside the silo 4, and the vibrator 9 continuously vibrates the silo 4 to prevent the material from accumulating and clogging in the silo.

[0033] Furthermore, the motor of the screw feeder 5 is a variable frequency motor, and the speed of the screw feeder can be adjusted and the conveying can be uniform through frequency conversion.

[0034] Furthermore, the pipe chain conveyor 6 includes a conveying pipeline, and a feed port and a discharge port are respectively arranged at both ends of the conveying pipeline. A conveying chain, a driving mechanism and a tensioning mechanism are arranged in the conveying pipeline. The conveying chain is arranged along the closed pipeline, and a chain piece is connected to the conveying chain. Under the traction of the driving mechanism, the conveying chain moves the material coming in from the feed port in a circular manner along the inner wall of the conveying pipeline to the discharge port for discharge, thereby completing the in-pipe transportation of the material. In the conveying pipeline, the chain piece is used as a transmission component to drive the material to move along the pipeline; when conveying horizontally, the material particles are thrust by the chain piece in the direction of movement. When the internal friction between the material layers is greater than the external friction between the material and the pipe wall, the material moves forward with the chain piece to form a stable material flow.

[0035] When starting the pipe chain conveyor 6, it is strictly forbidden to feed materials first and then start the machine. After the feeding of the pipe chain conveyor 6 is completed, the machine will run for a period of time until there is no material discharged from the discharge port before stopping. If there is an emergency stop and restart, it is necessary to perform jog operation several times or discharge the material in the machine in an appropriate amount before running.

[0036] Furthermore, a brush 10 is provided at the discharge port of the tube chain conveyor 6, and the brush 10 cleans the material adhering to the chain. A brush motor is installed to drive the brush to rotate. The brush motor is interlocked with the motor of the screw feeder. When the brush stops working, the screw feeder stops to prevent the material from accumulating on the tube chain conveyor and damaging the chain. The screw feeder can be frequency-controlled to control the conveying speed and uniform addition of the material.

[0037] Furthermore, the feed port and the discharge port of the tube chain conveyor 6 are provided with an observation port and an emergency processing port. The observation port is sealed with a transparent material (tempered glass, etc.), and the emergency processing port is a quick disassembly port.

[0038] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
