[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Reference Figure 1-6 The utility model provides an embodiment: a dust-proof conveying device for limestone processing, comprising a workbench 1, a processing cover 2 is fixedly connected to the top of the workbench 1, a bellows shell 3 is fixedly connected to the left side of the top of the processing cover 2, a controller 4 is fixedly connected to the front end of the processing cover 2, a connecting pipe 5 is fixedly connected to the right end of the bellows shell 3 and penetrates, a plurality of suction fans 6 are installed on the left end of the bellows shell 3, an electric conveying platform 7 is installed on the inner wall of the workbench 1, a dust filter net 8 is connected to the inner wall of the bellows shell 3 through a dust suction component, a second motor 10 is fixedly connected to the top of the inner wall of the workbench 1, and a first motor 9 is connected to the top of the processing cover 2 through a material discharge component. When the electric conveying platform 7 is started, the controller 4 controls the electric conveying platform 7 to convey materials, and the suction fan 6 is started to generate negative pressure in the bellows shell 3, so that the connecting pipe 5 can collect dust generated during the transportation of the electric conveying platform 7 through the dust collecting hopper 12.

[0028] Specifically, a lower hopper 14 is fixedly connected to the right side of the top of the processing cover 2 and penetrates through it. The driving end of the first motor 9 is fixedly connected to the first conveying wheel 11. The outer wall of the first conveying wheel 11 is connected to the second conveying wheel 13 through a transmission group. The front and rear sides of the bottom end of the lower hopper 14 are fixedly connected to an arc ring 17. The right side of the bottom end of the lower hopper 14 is rotatably connected to a lowering plate 16 through a return spring 18. The top of the return spring 18 is fixedly connected to the bottom sides of the front and rear ends of the lowering plate 16. The bottom ends of the return spring 18 are respectively fixedly connected to the bottom ends of the inner wall of the arc ring 17. The top of the lowering plate 16 is tightly attached to the bottom end of the conveyor belt 15. The second conveying wheel 13 and the outer walls of the dust collecting hopper 12 are meshed with the conveyor belt 15. The front and rear ends of the second conveying wheel 13 are respectively rotatably connected to the front and rear parts of the inner wall of the bottom right end of the lower hopper 14. When the limestone is transported, After being placed in the discharge hopper 14, the first motor 9 is started to rotate the first conveying wheel 11, so that the first conveying wheel 11 and the second conveying wheel 13 cooperate to rotate the conveyor belt 15. When the conveyor belt 15 rotates again, the protrusions on its outer wall squeeze the discharge plate 16 when rotating, so that the limestone in the discharge hopper 14 is lowered. During the rotation of the conveyor belt 15, when the protrusions at the conveyor belt 15 leave the discharge plate 16, the return spring 18 uses its own elastic force to make the discharge plate 16 fit again to the discharge hopper 14, so that the limestone in the discharge hopper 14 is discharged intermittently, avoiding dust generated when a large amount of limestone is discharged. After reducing dust, the working environment of the operator is cleaner and more comfortable, which helps to improve work efficiency and satisfaction, and can reduce failures caused by dust, ensuring continuous and stable production operation.

[0029] Specifically, a threaded rod 19 is fixedly connected to the driving end of the second motor 10, and a moving block 20 is threadedly connected to the outer wall of the threaded rod 19. The right end of the moving block 20 is rotatably connected to a connecting plate 21, and the right end of the connecting plate 21 is rotatably connected to a dust hopper 12. The outer wall of the top end of the dust hopper 12 is fixedly connected to the other end of the connecting pipe 5 and penetrates through it, and the left side of the top end of the dust hopper 12 is rotatably connected to the top of the inner wall of the processing cover 2. When the second motor 10 is started to rotate, the second motor 10 drives the threaded rod 19 to rotate, and the threaded rod 19 drives the moving block 20 to move, so that the moving block 20 pulls the dust hopper 12 through the connecting plate 21 to deflect, so that the dust suction angle at the dust hopper 12 is adjusted. By adjusting the angle of the dust hopper 12 and accurately locating the source of dust generation, dust can be more effectively captured and eliminated, and it is ensured that the dust hopper 12 covers a larger area and captures more dust particles.

[0030] Working principle: when the electric conveying platform 7 is started, the controller 4 controls the electric conveying platform 7 to convey materials, and the suction fan 6 is started to generate negative pressure in the bellows shell 3, so that the connecting pipe 5 can absorb the dust generated by the electric conveying platform 7 during transportation through the dust collecting hopper 12. When the limestone is transported, the limestone is placed in the lower hopper 14, and then the first motor 9 is started to rotate the first conveying wheel 11, so that the first conveying wheel 11 and the second conveying wheel 13 cooperate to rotate the conveyor belt 15, and when the conveyor belt 15 rotates again, the protrusions on its outer wall rotate to squeeze the lower plate 16, so that the limestone in the lower hopper 14 is lowered, and during the rotation of the conveyor belt 15, when the protrusions on the conveyor belt 15 leave the lower plate 16, the return spring 18 makes the lower plate 16 stick to it again through its own elastic force. The dust collecting hopper 12 is pulled by the connecting plate 21 to deflect the dust collecting hopper 12, and the dust collecting hopper 12 is adjusted. By adjusting the angle of the dust collecting hopper 12, the dust collecting hopper 12 is accurately located at the source of the dust, which can more effectively capture and eliminate the dust, and ensure that the dust collecting hopper 12 covers a larger area and captures more dust particles.
