[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. 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 in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0027] Since the traditional dust removal device adsorbs and removes the dust on the ore while transporting the ore, and the ore is in a static transportation state, in the actual dust removal process, it is difficult to completely suck away the dust on the bottom surface of the ore, resulting in incomplete dust removal of the ore. In order to enhance the dust removal effect of the dust removal device on the ore and improve the practicability of the dust removal device, with reference to Figures 1-5 , a dust removal device for ore selection is provided, which is composed of a dust removal barrel 1, a feeding hopper 2 and a dust removal mechanism 3. The feeding hopper 2 is fixedly connected and communicated with the top of the dust removal barrel 1, and the dust removal mechanism 3 is arranged on the dust removal barrel 1 and is used to remove the dust attached to the surface of the ore.

[0028] In order to remove all the dust on the surface of the ore during the falling process and improve the dust removal efficiency of the dust removal device, it is achieved by setting up a dust removal mechanism 3, which includes two receiving nets 31 that are fixedly installed inside the dust removal barrel 1 at intervals, and blanking nets 32 respectively arranged at the tops of the two receiving nets 31. The receiving net 31 is set in a funnel shape so that the ore can roll downward when it falls on the receiving net 31, and the blanking net 32 is set in a conical shape so that the ore rolls downward onto the receiving net 31 when it falls on the blanking net 32. Air outlets 33 are respectively opened on both sides of the dust removal barrel 1. A support frame 34 fixed to the dust removal barrel 1 is rotatably arranged at the bottom of the blanking net 32, and the support frame 34 is used to support the blanking net 32. When the ore falls on the blanking net 32, it can maintain stable rotation. A dust suction component 35 is arranged on one side of the dust removal barrel 1 to suck out the dust on the surface of the ore through the air outlet 33. A driving component 36 is also arranged inside the dust removal barrel 1 to synchronously drive the two blanking nets 32 to rotate. The dust removal mechanism 3 further includes a blanking component 37 arranged at the bottom of the feeding hopper 2 to prevent the blockage of the falling of gold ore fragments.

[0029] When dust-removing the ore, through the rotation of the blanking net 32, the ore on the blanking net 32 can be dropped onto the receiving net 31, which can extend the process of the ore rolling and falling. The driving component 36 includes a rotating vertical shaft 361 arranged inside the dust removal barrel 1, and the top end of the rotating vertical shaft 361 penetrates through the two blanking nets 32 and is fixedly connected to them. A scraping bar 362 rotatably arranged on the receiving net 31 and fixedly connected to the rotating vertical shaft 361 is also included. The scraping bar 362 rotates on the receiving net 31 to prevent the ore stuck on the receiving net 31 from not falling. The bottom end of the rotating vertical shaft 361 penetrates through the dust removal barrel 1 and is fixed with a worm gear. A servo motor 363 is fixedly installed at the bottom of the dust removal barrel 1, and a worm meshing with the worm gear is fixedly arranged on the output shaft of the servo motor 363. The transmission of the worm gear and the worm belongs to a speed reduction transmission, which can slow down the rotation speed of the rotating vertical shaft 361.

[0030] By starting the servo motor 363, the output shaft of the servo motor 363 drives the worm gear to rotate through the worm, the worm gear drives the rotating vertical shaft 361 at its top to rotate, the rotating vertical shaft 361 drives the two blanking nets 32 at its top to rotate. At the same time, the ore enters the dust removal barrel 1 from the feeding hopper 2. The ore first falls on the rotating first-layer blanking net 32, then rolls onto the first-layer receiving net 31, then rolls from the first-layer receiving net 31 onto the rotating second-layer blanking net 32, and then rolls from the second-layer blanking net 32 onto the second-layer receiving net 31. Finally, the ore falls to the bottom of the dust removal barrel 1 and is discharged through the discharge port. During the process of the ore rolling and falling, the dust on all surfaces of the ore is stirred up.

[0031] To avoid blockage between the feeding hopper 2 and the dust removal barrel 1 and improve the dust removal efficiency of the ore dust removal device, a feeding component 37 is provided, including a support baffle 371 fixedly arranged at the top of the dust removal barrel 1, and a rotating baffle 372 arranged on the top of the support baffle 371 and rotatably connected to the bottom of the feeding hopper 2. The top end of the rotating vertical shaft 361 penetrates through the support baffle 371 and is fixed to the rotating baffle 372. A number of feeding slots one 373 are arranged on the support baffle 371 in a circumferential array, and a number of feeding slots two 374 are arranged on the rotating baffle 372 in a circumferential array. The number of the feeding slots one 373 and the feeding slots two 374 is set to be the same and they are arranged staggeredly. When the rotating vertical shaft 361 rotates, it drives the rotating baffle 372 to rotate, and the feeding slots two 374 correspond to the feeding slots one 373, so that the ore can fall at intervals and prevent blockage.

[0032] When the ore rolls and falls, the dust stirred up is sucked away by the dust suction component 35 to ensure the dust removal effect. The dust suction component 35 includes a ventilation pipe 351 arranged on one side of the dust removal barrel 1, and a connecting pipe 352 fixedly connected to both ends of the ventilation pipe 351 and detachably arranged with the dust removal barrel 1. The two connecting pipes 352 are respectively matched with the two air discharge ports 33. A filter screen 353 matched with the air discharge port 33 is detachably arranged at the inner end of the connecting pipe 352. The filter screen 353 can prevent some ore debris from being adsorbed together with the dust, resulting in waste, and it is also convenient to disassemble and clean after long-term use. An air suction pump 354 is arranged at the bottom of one side of the dust removal barrel 1, and the output end of the air suction pump 354 is fixedly connected to the bottom end of the ventilation pipe 351. When the air suction pump 354 is started, the air suction pump 354 pumps air into the ventilation pipe 351, thereby driving the air flow in the storage barrel, sucking the dust stirred up in the storage barrel into the connecting pipe 352 through the air discharge port 33 and the filter screen 353, and then entering the ventilation pipe 351, so as to remove the dust on the surface of the ore.

[0033] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
